Abstract
Cigarette smoking puts individuals with or at risk for developing cardiovascular disease (CVD) in jeopardy of experiencing a major cardiovascular event. Contingency management (CM) for smoking cessation is an intervention wherein financial incentives are provided contingent on biochemically verified smoking abstinence. Conventional CM programs typically require frequent clinic visits for abstinence monitoring, a potential obstacle for patients with medical comorbidities who may face barriers to access. This preliminary study examined the feasibility and comparative efficacy of (a) usual care (UC; advice to quit smoking, self-help materials, quitline referral) versus (b) UC plus home-based CM for smoking cessation (UC + HBCM). HBCM entailed earning monetary-based vouchers contingent on self-reported 24-hr smoking abstinence biochemically verified by a breath carbon monoxide (CO) sample ≤ 6 ppm. Participants were 20 outpatients with a CVD diagnosis or qualifying CVD risk factor randomly assigned 1:1 to the two conditions. Intervention participants received 14 in-home abstinence visits over 6 weeks. Voucher monetary value started at $10 and escalated by $2.50 for each subsequent negative sample (maximum earnings: $367.50). Positive samples earned no vouchers and reset voucher value to $10, but two negative samples following a positive allowed participants to continue earning vouchers at the prereset value. Primary outcome was point-prevalence smoking abstinence at Week 6 assessment. More participants assigned to UC + HBCM than UC were smoking abstinent at that Week 6 assessment (90% vs. 30%), χ²(1, N = 20) = 7.5, p < .01. These results provide initial evidence that HBCM can effectively promote smoking abstinence in CVD outpatients. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Abstract
BACKGROUND Black adults who smoke and have HIV experience immense stressors (eg, racial discrimination and HIV stigma) that impede smoking cessation success and perpetuate smoking-related health disparities. These stressors also place Black adults who smoke and have HIV at an increased risk of elevated interoceptive stress (eg, anxiety and uncomfortable bodily sensations) and smoking to manage symptoms. In turn, this population is more likely to smoke to manage interoceptive stress, which contributes to worse HIV-related outcomes in this group. However, no specialized treatment exists to address smoking cessation, interoceptive stress, and HIV management for Black smokers with HIV. OBJECTIVE This study aims to test a culturally adapted and novel mobile intervention that targets combustible cigarette smoking, HIV treatment engagement and adherence, and anxiety sensitivity (a proxy for difficulty and responsivity to interoceptive stress) among Black smokers with HIV (ie, Mobile Anxiety Sensitivity Program for Smoking and HIV [MASP+]). Various culturally tailored components of the app are being evaluated for their ability to help users quit smoking, manage physiological stress, and improve health care management. METHODS This study is a pilot randomized controlled trial in which Black combustible cigarette smokers with HIV (N=72) are being recruited and randomly assigned to use either (1) the National Cancer Institute's QuitGuide app or (2) MASP+. Study procedures include a web-based prescreener; active intervention period for 6 weeks; smartphone-based assessments, including daily app-based ecological momentary assessments for 6 weeks (4 ecological momentary assessments each day); a video-based qualitative interview using Zoom Video Communications software at week 6 for participants in all study conditions; and smartphone-based follow-up assessments at 0, 1, 2 (quit date), 3, 4, 5, 6, and 28 weeks postbaseline (26 weeks postquitting date). RESULTS Primary outcomes include biochemically verified 7-day point prevalence of abstinence, HIV-related quality of life, use of antiretroviral therapy, and HIV care appointment adherence at 26 weeks postquitting date. Qualitative data are also being collected and assessed to obtain feedback that will guide further tailoring of app content and evaluation of efficacy. CONCLUSIONS The results of this study will determine whether the MASP+ app serves as a successful aid for combustible cigarette smoking cessation, HIV treatment engagement, and physiological stress outcomes among Black people with HIV infection. If successful, this study will provide evidence for the efficacy of a new means of addressing major mental and physical health difficulties for this high-risk population. If the results are promising, the data from this study will be used to update and tailor the MASP+ app for testing in a fully powered randomized controlled trial that will evaluate its efficacy in real-world behavioral health and social service settings.

Abstract
Background High prevalence (more than 80%) rates of tobacco smoking have been found both in, opioid-dependent subjects and among opioid-dependent subjects on opioid substitution treatment (OST) with buprenorphine or methadone. Aim We aimed to explore the efficacy of combined nicotine replacement therapy (NRT) and individual counseling (IC) when compared to NRT alone in subjects on OST with buprenorphine. Methods This study was carried out in a tertiary medical care center. It was an open-label randomized clinical trial. A total of 57 buprenorphine maintained smokers were recruited and randomized into two groups. They were assigned nicotine gum for 4 weeks plus either (1) a baseline IC session, and a second IC session after 1 week, or (2) simple advice to quit. In the first group, 31 subjects received NRT with IC and in the second group, 26 subjects received NRT plus simple advice to quit. The primary outcomes of this study were seven days point prevalence abstinence, biochemically confirmed by carbon monoxide (CO) breath analyzer, and reduction in smoking (mean no. of cigarettes or bidis/day). The smoking behavior during the 4 weeks follow-up period was assessed by the timeline follow-back (TLFB) method and confirmed by the CO breath analyzer. Results The group of subjects who received NRT with IC showed higher rates of smoking cessation at the end of treatment (51%) as compared to the NRT and simple advice group where smoking cessation rates were around 8% (P < 0.001). Conclusion A multi-component approach (pharmacotherapy and counseling) enhances treatment outcomes and enhances rates of abstinence from smoking.

Abstract
This pilot study tested the effect of a brief nicotine education messaging exposure on beliefs about nicotine, nicotine-replacement therapy (NRT), and e-cigarettes. Participants ages 18 and older were recruited via Amazon Mechanical Turk to complete a 20-min online survey in April/May 2020 to assess relationships between opioid use, smoking, and other behaviors. Participants with past-month extra-medical opioid use completed questions on background characteristics and literacy and then were randomized in a 2:1 ratio of two conditions: nicotine education (n = 362) or no message control (n = 181). Beliefs about nicotine, NRT, and e-cigarettes were asked of all participants; this occurred after message exposure for the nicotine education condition. Bivariate and multivariable analyses examined differences in beliefs by study condition. Brief nicotine messaging increased the probability of a correct response to "Nicotine is a cause of cancer" (false, 63% vs. 36%) and reduced the probability of a don't know response (9% vs. 17%) compared to the no message control condition. Nicotine education also reduced false beliefs about harms of long-term NRT use compared to cigarettes (p < .05). In adjusted models, participants in the nicotine education group had lower mean false beliefs about nicotine (p < .001) and to a lesser extent NRT (p = .053) compared with the control group; there was no difference in mean false beliefs about e-cigarettes (p = .547) between groups. A brief education intervention produced similar changes in nicotine beliefs in adults with past-month extra-medical opioid use as in a general adult sample. Findings support the potential for impact of nicotine public education messaging in vulnerable populations. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Abstract
BACKGROUND Black smokers have greater difficulty in quitting and higher rates of smoking-related diseases and disabilities than the general population. The smoking disparities experienced by this group are, in part, a consequence of multiple chronic life stressors (eg, racial discrimination) that engender increased exposure to interoceptive stress symptoms (eg, anxiety), which can ultimately lead to smoking as a means of immediate emotion regulation. OBJECTIVE This study aimed to culturally adapt and initially test a novel mobile intervention (ie, Mobile Anxiety Sensitivity Program for Smoking [MASP]) that targets anxiety sensitivity (AS; a proxy for difficulty and responsivity to interoceptive stress) among Black smokers. The MASP intervention is culturally informed to address interoceptive stress management difficulties among Black smokers and is thus hypothesized to facilitate smoking cessation. METHODS In phase 1, a total of 25 Black smokers with elevated AS will be administered MASP for 6 weeks. Following the completion of phase 1, we will further refine the MASP based on qualitative and quantitative data from participants to produce the final MASP iteration. In phase 2, a total of 200 Black smokers with elevated AS will be enrolled and randomly assigned to receive nicotine replacement therapy and either the smartphone-based National Cancer Institute QuitGuide app for standard mobile smoking cessation treatment or the MASP intervention. All participants in phases 1 and 2 will be enrolled remotely and will complete a web-based study screener; smartphone-based baseline assessment; daily smartphone-based ecological momentary assessments for 6 weeks; phone-based end-of-treatment qualitative interviews; and smartphone-based follow-up assessments at postbaseline weeks 1, 2 (quit date), 3, 4, 5, 6, 28, and 54 (weeks 28 and 54 follow-ups will be completed by phase 2 participants only). The MASP intervention is intended to offset barriers to treatment and encourage treatment engagement via smartphones. RESULTS This project was funded in September 2020. Phase 1 data collection began in January 2022. Phase 2 data collection is scheduled to begin in July 2022. CONCLUSIONS If successful, data from this study will support culturally informed treatment approaches for Black smokers and, pending findings of efficacy, provide an evidence-based mobile intervention for smoking cessation that is ready for dissemination and implementation.

Abstract
The field of applied behavior analysis (ABA) has produced powerful changes and improvements to the lives of many. However, the field is not immune from criticism. One criticism from those outside the field is that the goal of ABA therapy is to make Autistic people appear "indistinguishable" from their peers. This paper examines "indistinguishability" and its implications by defining "indistinguishable" in behavior analytic terms, exploring how the term was used in two notable studies in the field (Lovaas, 1987, Journal of Consulting and Clinical Psychology, 55[1], 3-9; Rekers & Lovaas, 1974, Journal of Applied Behavior Analysis, 7[2], 173-190), and providing a review of the social validity and ethical implications of having "indistinguishability" as an explicit or implied goal. This is partially accomplished by incorporating concerns from the Autistic self-advocate community. We argue that the Autistic self-advocate community's concerns surrounding "indistinguishability" as a goal have a degree of legitimacy and need to be given due consideration. Suggestions for addressing these concerns in ABA degree programs and research are discussed, emphasizing the importance of considering stakeholder values, taking criticisms seriously, and making changes when necessary.

Abstract
INTRODUCTION AND AIMS Tobacco smoking prevalence in opioid addiction patients is approximately six times that of the general population, highlighting the need for novel interventions. A pilot/feasibility study was conducted to investigate whether a contingency management (CM) intervention could be added to UK standard smoking cessation treatment. The aim of this report is to describe the challenges experienced during the implementation of this CM intervention. DESIGN AND METHODS A two-armed, randomised, pilot/feasibility study of a 5-week escalating with reset CM intervention, conducted as an adjunct to smoking cessation treatment in an outpatient drug and alcohol treatment centre. RESULTS Forty participants were recruited, but only 19 attended the baseline session. Ten participants attended all treatment sessions (25% retention), with only one contactable at 6-month follow-up. While smoking cessation clinic engagement was higher than previously, implementation issues included limited operating hours of the smoking treatment clinic, ineffective biochemical verification of abstinence and overly restrictive inclusion criteria. DISCUSSION AND CONCLUSIONS This study highlighted not only the difficulty of integrating CM interventions into standard smoking cessation treatment for this population, but also the potential of CM to engage this group with smoking cessation treatment. Future research in this area should consider increasing the availability and flexibility of smoking cessation treatment, and relaxing inclusion criteria to be more reflective of the opioid-treatment-seeking population. This study is registered on ClinicalTrials.gov (NCT03015597, https://clinicaltrials.gov/ct2/show/NCT03015597).

Abstract
BACKGROUND Socioeconomic disadvantage is associated with a reduced likelihood of smoking cessation. Smartphone ownership is increasing rapidly, including among low-income adults, and smartphone interventions for smoking cessation may increase access to smoking cessation treatment among socioeconomically disadvantaged adults. OBJECTIVE This study aimed to evaluate the feasibility of an automated smartphone-based approach to delivering financial incentives for smoking cessation. METHODS Socioeconomically disadvantaged adults initiating tobacco cessation treatment were followed from 1 week before a scheduled quit attempt through 26 weeks after the quit date. Participants received telephone counseling and nicotine replacement therapy. Smoking cessation was verified 5 times per week via smartphone prompts to self-report smoking status and submit a breath sample via a portable carbon monoxide (CO) monitor that was connected with participants' smartphones. Identity was verified during smoking status assessments using smartphone-based facial recognition software. When smoking abstinence and identity were verified, an automated credit card payment was triggered. Participants were incentivized for abstinence on the quit date and up to five days per week during the first 4 weeks after the scheduled quit date, with additional incentives offered during postquit weeks 8 and 12. In total, participants had the opportunity to earn up to US $250 in abstinence-contingent incentives over the first 12 weeks of the quit attempt. RESULTS Participants (N=16) were predominantly female (12/16, 75%) and non-Hispanic white (11/16, 69%), black (4/16, 25%), or Hispanic of any race (1/16, 6%). Most participants (9/16, 56%) reported an annual household income of <US $11,000. During the first 4 weeks after the scheduled quit date, participants completed a median of 16 (out of 21; range 1-21) mobile smoking status assessments, and they earned a median of US $28 in abstinence-contingent incentives (out of a possible US $150; range US $0-US $135). Median earnings did not change during the 8- and 12-week incentivized follow-up periods (total median earnings over 12 weeks=US $28; range US $0-US $167). During the first 4 weeks after the scheduled quit date, participants abstained from smoking on a median of 5 (out of 21) assessment days (range 0-20). At the in-person follow-up visits, the expired CO-confirmed 7-day point prevalence abstinence rates were 19% (3/16) and 13% (2/16) at 12 and 26 weeks postquit, respectively. Overall, most participants reported that the system was easy to use and that they would recommend this treatment to their friends and family. CONCLUSIONS Preliminary data suggest that this smartphone-based approach to verifying identity and smoking status and automating the delivery of abstinence-contingent incentives to a credit card is feasible for use among socioeconomically disadvantaged adults. However, continued refinement is warranted.

Abstract
While prevalence of tobacco use in the US general population is declining, prevalence among those with opioid use disorder (OUD) remains high and results in excessive tobacco-related disease and premature mortality. Among smokers with OUD, tobacco cessation rates are negligible without treatment. However, both low-intensity behavioral interventions and more intensive motivational interventions yield negligible cessation rates. While contingency management has potent short-term cessation effects, effects are not maintained at post-intervention follow-up. Evidence-based smoking cessation pharmacotherapies, such as nicotine replacement therapy, bupropion, and varenicline, result in very modest cessation rates among smokers with OUD. Intensification of pharmacotherapy, such as high-dose and combination nicotine replacement therapy or extended medication treatment, has failed to improve cessation outcomes compared with standard treatment regimens. Targeting the unique challenges faced by smokers with OUD, including nicotine-opioid interactions and poor medication adherence, has potential to improve cessation outcomes, but further research is needed to optimize intervention efficacy among smokers with OUD.

Abstract
Smoking rates are high among people with psychiatric illness. Smoking cessation interventions are rarely available in inpatient psychiatry settings. Smokers with psychiatric illness are just as interested in quitting smoking.
Background Tobacco-related diseases are a leading cause of death among individuals with severe mental illness (SMI), yet interventions to address tobacco cessation are rare in inpatient settings where persons with SMI are hospitalized. While cigarette smoking rates have declined in the general population, they remain high in persons with SMI. Inpatient settings would be a prime location to intervene on tobacco consumption among persons with SMI. The objective of this review was to examine evidence of smoking cessation interventions in psychiatric inpatient facilities. Method Using narrative overview guidelines, we searched PubMed, PsycINFO, and CINAHL for smoking cessation RCT studies published between 1950 and 2018. Studies included had to have at least started in inpatient psychiatry settings. Examples of search terms included: smoking cessation in inpatient psychiatry, smoking cessation in inpatient mental health treatment facilities, and smoking cessation and mental health. Results Following the inclusion criteria, eight RCT studies were reviewed. One study was among adolescent psychiatric inpatient smokers ages 13–17, and 7 were among adult psychiatric inpatients with mean age 41 years. Treatment periods lasting 8 to 12 weeks started in inpatient settings and continued post discharge. A combination of behavioral and pharmacological interventions were used. Pharmacological interventions were nicotine replacement therapies, and at least one study used varenicline. At baseline, participants smoked an average of 18.1 cigarettes per day. Conclusion Smoking cessation in inpatient psychiatry settings is rare or delayed. There is a need for more tailored treatments among this population to help them quit smoking.

Abstract
BACKGROUND Financial incentives, monetary or vouchers, are widely used in an attempt to precipitate, reinforce and sustain behaviour change, including smoking cessation. They have been used in workplaces, in clinics and hospitals, and within community programmes. OBJECTIVES To determine the long-term effect of incentives and contingency management programmes for smoking cessation. SEARCH METHODS For this update, we searched the Cochrane Tobacco Addiction Group Specialised Register, clinicaltrials.gov, and the International Clinical Trials Registry Platform (ICTRP). The most recent searches were conducted in July 2018. SELECTION CRITERIA We considered only randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to smoking cessation incentive schemes or control conditions. We included studies in a mixed-population setting (e.g. community, work-, clinic- or institution-based), and also studies in pregnant smokers. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods. The primary outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up (at least six months from the start of the intervention). In the trials of pregnant women we used abstinence measured at the longest follow-up, and at least to the end of the pregnancy. Where available, we pooled outcome data using a Mantel-Haenzel random-effects model, with results reported as risk ratios (RRs) and 95% confidence intervals (CIs), using adjusted estimates for cluster-randomised trials. We analysed studies carried out in mixed populations separately from those carried out in pregnant populations. MAIN RESULTS Thirty-three mixed-population studies met our inclusion criteria, covering more than 21,600 participants; 16 of these are new to this version of the review. Studies were set in varying locations, including community settings, clinics or health centres, workplaces, and outpatient drug clinics. We judged eight studies to be at low risk of bias, and 10 to be at high risk of bias, with the rest at unclear risk. Twenty-four of the trials were run in the USA, two in Thailand and one in the Phillipines. The rest were European. Incentives offered included cash payments or vouchers for goods and groceries, offered directly or collected and redeemable online. The pooled RR for quitting with incentives at longest follow-up (six months or more) compared with controls was 1.49 (95% CI 1.28 to 1.73; 31 RCTs, adjusted N = 20,097; I2 = 33%). Results were not sensitive to the exclusion of six studies where an incentive for cessation was offered at long-term follow up (result excluding those studies: RR 1.40, 95% CI 1.16 to 1.69; 25 RCTs; adjusted N = 17,058; I2 = 36%), suggesting the impact of incentives continues for at least some time after incentives cease.Although not always clearly reported, the total financial amount of incentives varied considerably between trials, from zero (self-deposits), to a range of between USD 45 and USD 1185. There was no clear direction of effect between trials offering low or high total value of incentives, nor those encouraging redeemable self-deposits.We included 10 studies of 2571 pregnant women. We judged two studies to be at low risk of bias, one at high risk of bias, and seven at unclear risk. When pooled, the nine trials with usable data (eight conducted in the USA and one in the UK), delivered an RR at longest follow-up (up to 24 weeks post-partum) of 2.38 (95% CI 1.54 to 3.69; N = 2273; I2 = 41%), in favour of incentives. AUTHORS' CONCLUSIONS Overall there is high-certainty evidence that incentives improve smoking cessation rates at long-term follow-up in mixed population studies. The effectiveness of incentives appears to be sustained even when the last follow-up occurs after the withdrawal of incentives. There is also moderate-certainty evidence, limited by some concerns about risks of bias, that incentive schemes conducted among pregnant smokers improve smoking cessation rates, both at the end of pregnancy and post-partum. Current and future research might explore more precisely differences between trials offering low or high cash incentives and self-incentives (deposits), within a variety of smoking populations.

Promoting smoking abstinence among patients with chronic obstructive pulmonary disease: Initial feasibility. Prev Med Rep 2018; 11:176-179.

Abstract
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the U.S., with the majority of COPD deaths attributable to cigarette smoking. Despite this, individuals with COPD have a higher prevalence of smoking, poorer quit rates, and higher relapse rates compared to smokers without a COPD diagnosis. We examined the feasibility of an incentives-based intervention for producing an initial period of biochemically-verified smoking abstinence among daily smokers with COPD. Participants were randomly assigned to a Contingent (n = 13) or Noncontingent (n = 16) incentives condition and visited the clinic for 14 consecutive days. Contingent participants earned vouchers with monetary value contingent on breath carbon monoxide (CO) levels during Study Days 1–5 and urinary cotinine during Days 6–14. Voucher earnings began at $9.00 and increased by $1.50 with each subsequent negative sample for maximum possible of $362.50. Noncontingent participants received vouchers of comparable value independent of smoking status. Differences between conditions varied across study days for daily smoking abstinence (X2 = 45.27, p < 0.0001), CO (F(13, 280) = 1.95, p = 0.025), and cotinine (F(13, 279) = 2.20, p = 0.010), with generally higher rates of abstinence and lower CO and cotinine levels observed in the Contingent vs. Noncontingent conditions. Results from this randomized pilot study support the potential efficacy of an incentives-based intervention for reducing cigarette smoking among individuals with COPD. Further research efforts should seek to promote and evaluate longer-term abstinence and associated changes in respiratory function.

Abstract
Prevalence of cigarette smoking among opioid-dependent individuals is 6-fold that of the general U.S. adult population and their quit rates are notoriously poor. One possible reason for the modest cessation outcomes in opioid-dependent smokers may be that they experience more severe tobacco withdrawal upon quitting. In this secondary analysis, we evaluated tobacco withdrawal in opioid-dependent (OD) smokers versus smokers without co-occurring substance use disorders (SUDs). Participants were 47 methadone- or buprenorphine-maintained smokers and 25 non-SUD smokers who completed 1 of several 2-week studies involving daily visits for biochemical monitoring, delivery of financial incentives contingent on smoking abstinence, and assessment of withdrawal via the Minnesota Nicotine Withdrawal Scale (MNWS). Prior to quitting smoking, OD smokers presented with higher baseline withdrawal scores than non-SUD smokers (1.7 ± 0.2 vs. 0.7 ± 0.2, respectively; F[1, 63] = 7.31, p < .001). Withdrawal scores in both groups decreased over the subsequent 2-week period with no group differences, F(1, 910) = 0.50, p = .48. A similar pattern was observed on craving (i.e., Desire to Smoke item of MNWS), although the trajectory of decrease over time on this item was also moderated by gender. Overall, there was no difference in withdrawal during biochemically verified smoking abstinence between OD and non-SUD smokers, suggesting that elevated withdrawal severity following quitting may not be a major factor contributing to the poor cessation outcomes consistently observed among OD smokers. Further scientific efforts are needed to improve our understanding of the high smoking rates and modest cessation outcomes in this challenging population. (PsycINFO Database Record

Abstract
Introduction Abstinence reinforcement is efficacious for improving smoking treatment outcomes, but practical constraints related to the need for multiple in-person carbon monoxide (CO) breath tests daily to verify smoking abstinence have limited its use. This study tested an mHealth procedure to remotely monitor and reinforce smoking abstinence in individuals' natural environment. Methods Eligible treatment-seeking smokers (N = 90) were randomized to (1) usual care and ecological monitoring with abstinence reinforcement (mHealth reinforcement) or (2) without reinforcement (mHealth monitoring). Usual care was 8 weeks of transdermal nicotine and twice-weekly telephone counseling. Following training, an interactive voice response system prompted participants to conduct CO tests 1-3 daily at pseudorandom times (7 am to 10 pm) for 4 weeks. When prompted, participants used a study cell phone and CO monitor to complete a CO self-test, video record the process, and submit videos using multimedia messaging. mHealth reinforcement participants could earn prizes for smoking-negative on-time CO tests. The interactive voice response generated preliminary earnings immediately. Earnings were finalized by comparing video records against participants' self-reports. Results mHealth reinforcement was associated with a greater proportion of smoking-negative CO tests, longest duration of prolonged abstinence, and point-prevalence abstinence during the monitoring/reinforcement phase compared to mHealth monitoring (p < .01, d = 0.8-1.3). Follow-up (weeks 4-24) analyses indicated main effects of reinforcement on point-prevalence abstinence and proportion of days smoked (p ≤ .05); values were comparable by week 24. Conclusions mHealth reinforcement has short-term efficacy. Research on methods to enhance and sustain benefits is needed. Implications This study suggests that mHealth abstinence reinforcement is efficacious and may present temporal and spatial opportunities to research, engage, and support smokers trying to quit that do not exist with conventional (not technology-based) reinforcement interventions.

Abstract
INTRODUCTION Smoking rates among individuals in treatment for opioid addiction are close to five times that of the general public. Moreover, drug-addicted smokers have a premature mortality rate four times greater than drug-addicted non-smokers. The aim of this pilot study was to investigate whether contingency management (CM) can be successfully added to evidence-based stop smoking treatment in individuals undergoing treatment for opioid addiction and assess preliminary evidence for its impact. PARTICIPANTS Forty tobacco smokers currently undergoing treatment for opioid addiction. INTERVENTION Escalating with reset CM as an adjunct to standard smoking cessation treatment. Financial incentives will be administered over a 5-week period for either biochemically verified abstinence from smoking or attendance at the clinic. Participants will be randomised to conditions stratified on current levels of smoking (high or low). OBJECTIVES AND ANALYSES To assess whether a CM intervention can be successfully added to standard stop smoking services treatment, in patients undergoing outpatient treatment for opioid addiction. This will be measured as the number of people completing the 5 weeks of the intervention. ETHICS AND DISSEMINATION Ethics approval for the study was granted on the 16 June 2016 by the London-city and east (reference 16/LO/0990) ethics committee. The pilot study was retrospectively registered on clincaltrials.gov in January 2017 (ID: NCT03015597). A SPIRIT checklist and figure are available for this protocol. It is planned that the results of this study will be published in an academic journal.

Abstract
BACKGROUND Contingency management (CM) has demonstrated its efficacy in treating many drug addictions, including nicotine. However, one of the most commonly perceived limitations with regard to its dissemination into community settings is whether this protocol could be equally effective for treating patients across different income levels. OBJECTIVE This study aimed to examine whether individuals' income levels affect treatment success in a cognitive behavioral treatment (CBT) that included a voucher-based CM protocol for smoking cessation. METHODS A total of 92 treatment-seeking smokers in a community setting were randomly assigned to a CBT group (N = 49) or to a CBT plus CM group (N = 43). The CM procedure included a voucher program through which smoking abstinence was reinforced on a schedule of escalating magnitude of reinforcement with a reset contingency. We analyzed the impact of self-reported monthly income, alone and in combination with treatment condition, on short-term (treatment retention) and long-term (self-reported number of days of continuous smoking abstinence at 6-month follow-up) results. RESULTS Income had no effect on treatment retention and continuous abstinence outcomes at 6-month follow-up in either treatment condition. Treatment modality emerged as the only significant predictor of treatment success. CONCLUSIONS Our findings suggest that treatment-seeking smokers from the general population respond equally well to CM regardless of their income levels. The results of this randomized controlled trial support the generalizability of this evidenced-based program into community settings.

Abstract
Substantial reductions in U.S. cigarette smoking and associated chronic diseases over the past 50 years have benefited health. Unfortunately, those reductions have distributed unevenly throughout the population. Smoking remains prevalent and even increasing among certain vulnerable populations: economically disadvantaged groups, those with other substance-use disorders or mental illness, certain ethnic and racial minorities, and gender and sexual minorities. Moreover, other unhealthy behavior patterns (physical inactivity, unhealthy food choices, risky sexual behavior, poor adherence to medical preventive regimens) and associated chronic diseases are also overrepresented in many of these same populations. Disparities in unhealthy behavior patterns contribute to health disparities and escalating health care costs, underscoring the need for more effective behavior-change strategies. This report reviews research on the efficacy of financial incentives for reducing smoking in vulnerable populations, while also touching on applications of that behavior-change strategy for promoting other health-related behavior changes in vulnerable populations.

Abstract
This article introduces the special issue on contingency management (CM), an efficacious intervention for the treatment of substance use disorders with low uptake in clinical settings that is not commensurate with evidence for efficacy. In this special issue of the Journal of Substance Abuse Treatment, we present 16 articles representing the latest research in efficacy, implementation, and technological advances related to CM. Combined, this collection of articles highlights the diverse populations, settings, and applications of CM in the treatment of substance use disorders. We conclude by highlighting directions for future research, particularly those that may increase CM's appeal and uptake in routine clinical care.

Abstract
BACKGROUND Smoking rates in people with alcohol and other drug dependencies are two to four times those of the general population. Concurrent treatment of tobacco dependence has been limited due to concern that these interventions are not successful in this population or that recovery from other addictions could be compromised if tobacco cessation was combined with other drug dependency treatment. OBJECTIVES To evaluate whether interventions for tobacco cessation are associated with tobacco abstinence for people in concurrent treatment for or in recovery from alcohol and other drug dependence. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and clinicaltrials.gov databases, with the most recent search completed in August 2016. A grey literature search of conference abstracts from the Society on Nicotine Research and Treatment and the ProQuest database of digital dissertations yielded one additional study, which was excluded. SELECTION CRITERIA We included randomised controlled trials assessing tobacco cessation interventions among people in concurrent treatment for alcohol or other drug dependence or in outpatient recovery programmes. DATA COLLECTION AND ANALYSIS Two review authors independently assessed study risk of bias and extracted data. We resolved disagreements by consensus. The primary outcome was abstinence from tobacco use at the longest period of follow-up, and the secondary outcome was abstinence from alcohol or other drugs, or both. We reported the strictest definition of abstinence. We summarised effects as risk ratios and 95% confidence intervals (CI). Two clustered studies did not provide intraclass correlation coefficients, and were excluded from the sensitivity analysis. We used the I2 statistic to assess heterogeneity. MAIN RESULTS Thirty-five randomised controlled trials, one ongoing, involving 5796 participants met the criteria for inclusion in this review. Included studies assessed the efficacy of tobacco cessation interventions, including counselling, and pharmacotherapy consisting of nicotine replacement therapy (NRT) or non-NRT, or the two combined, in both inpatient and outpatient settings for participants in treatment and in recovery. Most studies did not report information to assess the risk of allocation, selection, and attrition bias, and were classified as unclear.Analyses considered the nature of the intervention, whether participants were in treatment or recovery and the type of dependency. Of the 34 studies included in the meta-analysis, 11 assessed counselling, 11 assessed pharmacotherapy, and 12 assessed counselling in combination with pharmacotherapy, compared to usual care or no intervention. Tobacco cessation interventions were significantly associated with tobacco abstinence for two types of interventions. Pharmacotherapy appeared to increase tobacco abstinence (RR 1.60, 95% CI 1.22 to 2.12, 11 studies, 1808 participants, low quality evidence), as did combined counselling and pharmacotherapy (RR 1.74, 95% CI 1.39 to 2.18, 12 studies, 2229 participants, low quality evidence) at the period of longest follow-up, which ranged from six weeks to 18 months. There was moderate evidence of heterogeneity (I2 = 56% with pharmacotherapy and 43% with counselling plus pharmacotherapy). Counselling interventions did not significantly increase tobacco abstinence (RR 1.33, 95% CI 0.90 to 1.95).Interventions were significantly associated with tobacco abstinence for both people in treatment (RR 1.99, 95% CI 1.59 to 2.50) and people in recovery (RR 1.33, 95% CI 1.06 to 1.67), and for people with alcohol dependence (RR 1.47, 95% CI 1.20 to 1.81) and people with other drug dependencies (RR 1.85, 95% CI 1.43 to 2.40).Offering tobacco cessation therapy to people in treatment or recovery for other drug dependence was not associated with a difference in abstinence rates from alcohol and other drugs (RR 0.97, 95% CI 0.91 to 1.03, 11 studies, 2231 participants, moderate evidence of heterogeneity (I2 = 66%)).Data on adverse effect of the interventions were limited. AUTHORS' CONCLUSIONS The studies included in this review suggest that providing tobacco cessation interventions targeted to smokers in treatment and recovery for alcohol and other drug dependencies increases tobacco abstinence. There was no evidence that providing interventions for tobacco cessation affected abstinence from alcohol and other drugs. The association between tobacco cessation interventions and tobacco abstinence was consistent for both pharmacotherapy and combined counselling and pharmacotherapy, for participants both in treatment and in recovery, and for people with alcohol dependency or other drug dependency. The evidence for the interventions was low quality due primarily to incomplete reporting of the risks of bias and clinical heterogeneity in the nature of treatment. Certain results were sensitive to the length of follow-up or the type of pharmacotherapy, suggesting that further research is warranted regarding whether tobacco cessation interventions are associated with tobacco abstinence for people in recovery, and the outcomes associated with NRT versus non-NRT or combined pharmacotherapy. Overall, the results suggest that tobacco cessation interventions incorporating pharmacotherapy should be incorporated into clinical practice to reduce tobacco addiction among people in treatment for or recovery from alcohol and other drug dependence.

Abstract
OBJECTIVE An unsettling aspect of the US opioid epidemic is the high rate of in utero exposure, especially since most of these pregnancies are unintended, due in part to low rates of effective contraceptive use among opioid-using women. This study tested an intervention informed by behavioral economic theory and aimed at promoting effective contraceptive use among opioid-maintained women at risk of unintended pregnancy in the Burlington, VT, area between 2011 and 2013. METHODS Thirty-one women were assigned (initial 5 consecutively, subsequent 26 randomly) to either usual care or an experimental intervention. Participants in usual care received condoms, a dose of emergency contraception, and referral to local providers. Participants in the experimental condition received usual care plus the World Health Organization's contraception initiation protocol, including free prescription contraceptives, and financial incentives for attending 13 follow-up visits over 6months to help manage side effects and other issues. RESULTS Significantly more women in the experimental vs. usual care control conditions initiated prescription contraceptive use (100% vs. 29%) and reported prescription contraceptive use at 1-month (63% vs. 13%), 3-month (88% vs. 20%), and 6-month (94% vs. 13%) assessments. None of the experimental condition participants became pregnant during the 6-month protocol vs. three women (20%) in the control condition. CONCLUSIONS These results provide the first experimental evidence supporting the efficacy of an intervention for increasing prescription contraceptive use among opioid-maintained women at risk of unintended pregnancy.

J Subst Abuse Treat 2016; 72:72-79. [PMID: 27658756 DOI: 10.1016/j.jsat.2016.08.012] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2016] [Revised: 06/23/2016] [Accepted: 08/08/2016] [Indexed: 10/21/2022]
Abstract
Treatment for substance use disorders (SUD) provides an opportunity to use voucher-based treatment for smoking. Nicotine replacement (NRT) could improve outcomes previously observed with vouchers without NRT. METHODS A randomized controlled trial compared contingent vouchers (CV) for smoking abstinence to noncontingent vouchers (NV), when all received counseling and NRT. Smokers who had not sought smoking treatment (n=340) in residential SUD treatment were provided 14days of vouchers for complete smoking abstinence per exhaled carbon monoxide (CO) after a 5-day smoking reduction period, or vouchers only for breath samples, plus brief advice (four sessions) and 8weeks of NRT. RESULTS Within treatment, 20% had complete abstinence with CV, 5% with NV (p<.001), and participants showed 50% of days abstinent in CV compared to 22% in NV (p<.001). Across 1, 3, 6 and 12months after randomization, CV resulted in significantly fewer cigarettes per day (p<.01) and fewer days smoking (p<.01), but with small effects. Point-prevalence abstinence differences across follow-up (e.g., 4% CV, 2% in NV at 6 and 12months) were not significant. No differences in substance use were seen. CONCLUSIONS Within-treatment effects on abstinence are stronger than in a prior study of the same CV with BA but without NRT, but NRT does not improve abstinence after vouchers end. Implications for voucher-based treatment include investigating effects when combined with stronger smoking medications and using motivational interviewing. Smoking treatment does not harm SUD recovery.

Abstract
INTRODUCTION This randomized clinical trial was designed to evaluate the efficacy of contingency management (CM) for smoking cessation for smokers with alcohol abuse or dependence delivered concurrently with intensive outpatient alcohol treatment. The study also explored the indirect effects of CM smoking treatment and smoking cessation on alcohol and drug use outcomes. METHODS Alcohol abuse/dependent smokers were randomized to cognitive behavioral therapy plus nicotine replacement therapy plus contingency management (CBT+NRT+CM) or to cognitive behavior therapy plus nicotine replacement therapy (CBT+NRT) delivered concurrent with a three-week intensive outpatient alcohol treatment program. RESULTS Participants in the CBT+NRT+CM condition were significantly more likely to be cigarette abstinent at the end of treatment (χ2(1)=8.48, p=.004) with approximately double the carbon monoxide confirmed quit rate (60%) compared with the CBT+NRT condition (29%). At the one-month and six-month time-points there were nonsignificant differences in smoking abstinence outcomes by condition. Smoking treatment condition did not directly affect alcohol abstinence outcomes, but we observed an indirect effect of smoking treatment on alcohol and drug abstinence at one-month follow-up that was mediated by smoking cessation at the end of treatment. CONCLUSIONS Adding CM to an evidence-based smoking cessation treatment that included medication and behavioral counseling doubled the quit rate at the end of treatment. This finding provides strong evidence for the efficacy of CM for helping alcohol dependent smokers reach the milestone of initial smoking abstinence.

Addiction 2016; 111:903-12. [PMID: 26638126 PMCID: PMC4826799 DOI: 10.1111/add.13264] [Citation(s) in RCA: 24] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2015] [Revised: 11/20/2015] [Accepted: 11/23/2015] [Indexed: 11/27/2022]
Abstract
BACKGROUND AND AIMS Prior studies by our group demonstrated the efficacy of a brief but intensive behavioral intervention for producing initial smoking abstinence among opioid-dependent patients. In the present study, our aim was to promote longer-duration abstinence in this population. Following an initial 2-week incentive intervention for smoking abstinence, we examined whether a 10-week maintenance arm involving continuation of contingent reinforcement will produce greater smoking abstinence than a similar duration of noncontingent reinforcement. DESIGN Randomized, 12-week, parallel-group study. SETTING Out-patient research clinic in Burlington, Vermont, USA. PARTICIPANTS Opioid-maintained smokers (n = 88) who provided breath carbon monoxide and urinary cotinine specimens and received contingent reinforcement for smoking abstinence during weeks 1-2 (phase 1), with 63 randomized on day 14 to an extended contingent (EC; n = 31) or extended noncontingent (EN; n = 32) experimental condition for weeks 3-12 (phase 2). INTERVENTION AND CONTROL The EC condition consisted of voucher values that escalated across consecutive negative samples until they reached $30, after which they remained at $30 per negative sample. A positive or a missing sample resulted in no vouchers for that day and reset the value of the next negative same to $9. Two consecutive negatives returned the schedule to the pre-reset value. The EN control condition consisted of vouchers delivered for providing scheduled samples, but independent of smoking status. MEASUREMENTS The primary outcome was percentage of biochemically abstinent samples during phase 2. Secondary measures included abstinence status at final study visit, complete abstinence, participants' longest duration of continuous abstinence, cotinine and carbon monoxide (CO) levels and self-reported cigarettes per day. FINDINGS EC participants achieved greater smoking abstinence during phase 2 than EN participants [46.7 versus 23.5% negative samples, respectively; odds ratio (OR) = 2.98, 95% confidence interval (CI) = 1.16-7.65, χ(2) 1 (=) 5.0, P = 0.02]. When longest duration of continuous abstinence was compared between experimental groups, EC participants achieved twice the mean duration of continuous abstinence compared with EN participants (3.31 versus 1.68 weeks; t61 = 1.83, P = 0.07). An effect of experimental condition was also seen on mean cotinine levels (42.5 versus 210.6 ng/ml, respectively; F1,61 =5.9, P = 0.02). CONCLUSIONS Among opioid-maintained smokers receiving an initial period of daily contingent incentives, a contingent reinforcement intervention appears to be more effective at extending smoking abstinence than noncontingent reinforcement over 10 weeks.

Blunted striatal response to monetary reward anticipation during smoking abstinence predicts lapse during a contingency-managed quit attempt. Psychopharmacology (Berl) 2016; 233:751-60. [PMID: 26660448 PMCID: PMC5330670 DOI: 10.1007/s00213-015-4152-2] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/20/2015] [Accepted: 11/10/2015] [Indexed: 10/22/2022]
Abstract
RATIONALE Tobacco smoking is associated with dysregulated reward processing within the striatum, characterized by hypersensitivity to smoking rewards and hyposensitivity to non-smoking rewards. This bias toward smoking reward at the expense of alternative rewards is further exacerbated by deprivation from smoking, which may contribute to difficulty maintaining abstinence during a quit attempt. OBJECTIVE We examined whether abstinence-induced changes in striatal processing of rewards predicted lapse likelihood during a quit attempt supported by contingency management (CM), in which abstinence from smoking was reinforced with money. METHODS Thirty-six non-treatment-seeking smokers participated in two functional MRI (fMRI) sessions, one following 24-h abstinence and one following smoking as usual. During each scan, participants completed a rewarded guessing task designed to elicit striatal activation in which they could earn smoking and monetary rewards delivered after the scan. Participants then engaged in a 3-week CM-supported quit attempt. RESULTS As previously reported, 24-h abstinence was associated with increased striatal activation in anticipation of smoking reward and decreased activation in anticipation of monetary reward. Individuals exhibiting greater decrements in right striatal activation to monetary reward during abstinence (controlling for activation during non-abstinence) were more likely to lapse during CM (p < 0.025), even when controlling for other predictors of lapse outcome (e.g., craving); no association was seen for smoking reward. CONCLUSIONS These results are consistent with a growing number of studies indicating the specific importance of disrupted striatal processing of non-drug reward in nicotine dependence and highlight the importance of individual differences in abstinence-induced deficits in striatal function for smoking cessation.

Abstract
While rates of smoking in the general population have decreased in recent years, dramatic disparities remain among disadvantaged subgroups of smokers, particularly those with concurrent substance abuse. Prevalence rates of smoking among opioid-dependent patients, for example, are fourfold those of the general population. While pharmacotherapies are recommended as a first-line treatment for nicotine dependence, the few studies that have investigated their effectiveness in this population have shown dramatically poorer outcomes compared to the general population. Indeed, these findings have led some researchers to suggest that pharmacotherapies may simply be ineffective in opioid-maintained smokers. In this commentary, we briefly summarize the extant literature on pharmacotherapies in opioid-maintained smokers and contribute new data investigating the contribution of bupropion on smoking outcomes in 81 methadone- and buprenorphine-maintained participants from two randomized trials of financial incentives for smoking cessation. We also discuss several important parameters (ie, timing of the quit attempt, medication adherence, nicotine withdrawal) that may be leveraged to strengthen smoking pharmacotherapy outcomes in opioid-dependent patients. Taken together, an improved understanding of these issues will aid efforts to reduce tobacco-related health disparities in this group of challenging smokers.

Abstract
A high percentage of patients relapse within months following an attempt to quit smoking. For this reason, greater understanding of the determinants of successful smoking cessation is needed. The present study assessed the effect of Contingency Management (CM) combined with Cognitive-Behavioral Treatment (CBT) on certain in-treatment behaviors (treatment retention, in-treatment smoking abstinence, and weekly decrease of cotinine levels) and examined the effects of these in-treatment behaviors on smoking status at a 6-month follow-up. A total of 154 treatment-seeking patients in a community setting were randomly assigned to a CBT, CBT plus CM for Abstinence (CMA) or to a CBT plus CM for Shaping cessation (CMS) group. Both CBT + CM procedures improved the in-treatment behaviors compared to CBT alone. These in-treatment behaviors (particularly in-treatment smoking abstinence) were associated with long-term abstinence. The effect of CM on in-treatment behaviors may partially explain the positive long-term outcomes of this procedure. Our findings extend previous knowledge about the effect of CM on smoking behavior.

Abstract
Residential drug treatment provides an opportunity to intervene with smokers with substance use disorders (SUD). A randomized controlled clinical trial compared: (1) contingent vouchers (CV) for smoking abstinence to noncontingent vouchers (NCV), crossed with (2) motivational interviewing (MI) or brief advice (BA), for 184 smokers in SUD treatment. During the voucher period, 36% of carbon monoxide readings indicated smoking abstinence for those receiving CV versus 13% with NCV (p < .001). Post-treatment (3-9 months) point-prevalence abstinence rates were low (3-4% at each follow up), with more abstinence when CV was combined with MI (6.6% on average) than with BA (0% on average). No differential effects on drug use or motivation to quit smoking occurred. Thus, CV had limited effects on long-term smoking abstinence in this population but effects were improved when CV was combined with MI. More effective methods are needed to increase motivation to quit smoking and quit rates in this high-risk population.

Abstract
INTRODUCTION Smoking rates are 80% among persons who are homeless, and these smokers have decreased odds of quitting smoking. Little is known about relapse rates among homeless smokers. More information is needed regarding both quit rates and innovative methods to treat smoking cessation among homeless smokers. Web-based contingency management (CM) approaches have been found helpful in reducing smoking among other difficult-to-treat smoker populations but have been generally limited by the need for computers or frequent clinic-based carbon monoxide (CO) monitoring. This open pilot study builds on a web-based CM approach by evaluating a smartphone-based application for CM named mobile CM (mCM). The study was conducted from January 1, 2013-April 15, 2014. METHOD Following a 1-week training period, 20 homeless veteran smokers (≥ 10 cigarettes daily for 1 year or more and a CO baseline level ≥ 10 ppm) participated in a multicomponent smoking cessation intervention including 4 weeks of mCM. All smokers received 4 smoking cessation counseling sessions, nicotine replacement, and bupropion (if medically eligible). Participants could earn up to $815 ($480 for mCM, $100 for CO readings showing abstinence [ie, 6 ppm or less] at posttreatment and follow-up, and $35 for equipment return). RESULTS Mean compensation for the mCM component was $286 of a possible $480. Video transmission compliance was high during the 1-week training (97%) and the 4-week treatment period (87%). Bioverified 7-day point prevalence abstinence was 50% at 4 weeks. Follow-up bioverified single assessment point prevalence abstinence was 55% at 3 months and 45% at 6 months. CONCLUSIONS Results of this open pilot study suggest that mCM may be a useful adjunctive smoking cessation treatment component for reducing smoking among homeless veterans.

Abstract
OBJECTIVES We evaluated the effectiveness of offering adjunctive financial incentives for abstinence (contingency management [CM]) within a safety net hospital smoking cessation program. METHODS We randomized participants (n = 146) from a Dallas County, Texas, Tobacco Cessation Clinic from 2011 to 2013 to usual care (UC; cessation program; n = 71) or CM (UC + 4 weeks of financial incentives; n = 75), and followed from 1 week before the quit date through 4 weeks after the quit date. A subset (n = 128) was asked to attend a visit 12 weeks after the scheduled quit date. RESULTS Participants were primarily Black (62.3%) or White (28.1%) and female (57.5%). Most participants were uninsured (52.1%) and had an annual household income of less than $12 000 (55.5%). Abstinence rates were significantly higher for those assigned to CM than UC at all visits following the quit date (all Ps < .05). Point prevalence abstinence rates in the CM and UC groups were 49.3% versus 25.4% at 4 weeks after the quit date and 32.8% versus 14.1% at 12 weeks after the quit date. CM participants earned an average of $63.40 ($150 possible) for abstinence during the first 4 weeks after the scheduled quit date. CONCLUSIONS Offering small financial incentives for abstinence might be an effective means to improve abstinence rates among socioeconomically disadvantaged individuals participating in smoking cessation treatment.

Abstract
BACKGROUND Material or financial incentives are widely used in an attempt to precipitate or reinforce behaviour change, including smoking cessation. They operate in workplaces, in clinics and hospitals, and to a lesser extent within community programmes. In this third update of our review we now include trials conducted in pregnant women, to reflect the increasing activity and resources now targeting this high-risk group of smokers. OBJECTIVES To determine whether incentives and contingency management programmes lead to higher long-term quit rates. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. The most recent searches were in December 2014, although we also include two trials published in 2015. SELECTION CRITERIA We considered randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. We include studies in a mixed-population setting (e.g. community-, work-, institution-based), and also, for this update, trials in pregnant smokers. DATA COLLECTION AND ANALYSIS One author (KC) extracted data and a second (JH-B) checked them. We contacted study authors for additional data where necessary. The main outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up, and at least six months from the start of the intervention. In the trials of pregnant smokers abstinence was measured at the longest follow-up, and at least to the end of the pregnancy. MAIN RESULTS Twenty-one mixed-population studies met our inclusion criteria, covering more than 8400 participants. Ten studies were set in clinics or health centres, one in Thai villages served by community health workers, two in academic institutions, and the rest in worksites. All but six of the trials were run in the USA. The incentives included lottery tickets or prize draws, cash payments, vouchers for goods and groceries, and in six trials the recovery of money deposited by those taking part. The odds ratio (OR) for quitting with incentives at longest follow-up (six months or more) compared with controls was 1.42 (95% confidence interval (CI) 1.19 to 1.69; 17 trials, [20 comparisons], 7715 participants). Only three studies demonstrated significantly higher quit rates for the incentives group than for the control group at or beyond the six-month assessment: One five-arm USA trial compared rewards- and deposit-based interventions at individual and group level, with incentives available up to USD 800 per quitter, and demonstrated a quit rate in the rewards groups of 8.1% at 12 months, compared with 4.7% in the deposits groups. A direct comparison between the rewards-based and the deposit-based groups found a benefit for the rewards arms, with an OR at 12 months of 1.76 (95% CI 1.22 to 2.53; 2070 participants). Although more people in this trial accepted the rewards programmes than the deposit programmes, the proportion of quitters in each group favoured the deposit-refund programme. Another USA study rewarded both participation and quitting up to USD 750, and achieved sustained quit rates of 9.4% in the incentives group compared with 3.6% for the controls. A deposit-refund trial in Thailand also achieved significantly higher quit rates in the intervention group (44.2%) compared with the control group (18.8%), but uptake was relatively low, at 10.5%. In the remaining trials, there was no clear evidence that participants who committed their own money to the programme did better than those who did not, or that contingent rewards enhanced success rates over fixed payment schedules. We rated the overall quality of the older studies as low, but with later trials (post-2000) more likely to meet current standards of methodology and reporting.Eight of nine trials with usable data in pregnant smokers (seven conducted in the USA and one in the UK) delivered an adjusted OR at longest follow-up (up to 24 weeks post-partum) of 3.60 (95% CI 2.39 to 5.43; 1295 participants, moderate-quality studies) in favour of incentives. Three of the trials demonstrated a clear benefit for contingent rewards; one delivered monthly vouchers to confirmed quitters and to their designated 'significant other supporter', achieving a quit rate in the intervention group of 21.4% at two months post-partum, compared with 5.9% among the controls. Another trial offered a scaled programme of rewards for the percentage of smoking reduction achieved over the course of the 12-week intervention, and achieved an intervention quit rate of 31% at six weeks post-partum, compared with no quitters in the control group. The largest (UK-based) trial provided intervention quitters with up to GBP 400-worth of vouchers, and achieved a quit rate of 15.4% at longest follow-up, compared to the control quit rate of 4%. Four trials confirmed that payments made to reward a successful quit attempt (i.e. contingent), compared to fixed payments for attending the antenatal appointment (non-contingent), resulted in higher quit rates. Front-loading of rewards to counteract early withdrawal symptoms made little difference to quit rates. AUTHORS' CONCLUSIONS Incentives appear to boost cessation rates while they are in place. The two trials recruiting from work sites that achieved sustained success rates beyond the reward schedule concentrated their resources into substantial cash payments for abstinence. Such an approach may only be feasible where independently-funded smoking cessation programmes are already available, and within a relatively affluent and educated population. Deposit-refund trials can suffer from relatively low rates of uptake, but those who do sign up and contribute their own money may achieve higher quit rates than reward-only participants. Incentive schemes conducted among pregnant smokers improved the cessation rates, both at the end-of-pregnancy and post-partum assessments. Current and future research might continue to explore the scale, loading and longevity of possible cash or voucher reward schedules, within a variety of smoking populations.

Abstract
INTRODUCTION Individuals with substance use disorders (SUDs) experience increased smoking-related morbidity and mortality but severely compromised smoking treatment benefits. Residential SUD treatment settings may be particularly positioned to target smoking, with ever-increasing smoking bans and culture shifts, but most smokers continue smoking. This study examined the effects of contingency management (CM) for increasing smoking abstinence in residential patients. METHODS Smokers interested in quitting were recruited from a residential SUD program for men and were randomized to frequent smoking monitoring with behavioral support (monitoring; n = 21) or that plus smoking abstinence-contingent (expired carbon monoxide [CO] ≤ 6 ppm; urinary cotinine ≤ 30ng/ml) incentives (CM, n = 24) for 4 weeks. After setting a quit date, procedures included daily behavioral support and smoking self-reports, 2 CO samples (a.m./p.m.) Monday through Friday, and cotinine tests on Mondays. CM participants received escalating draws for prizes ($1, $20, and $100 values) for negative tests; positive and missed samples reset draws. Follow-ups involved samples, self-reported smoking, and self-efficacy (weeks 4, 8, 12, and 24). RESULTS Percent days CO-negative was higher with CM (median [interquartile range] 51.7% [62.8%]) compared to monitoring (0% [32.1%]) (p = .002). Cigarettes per day declined and point-prevalence abstinence increased through follow-up (p < .01), without significant group by time effects (p > .05). Abstinence self-efficacy increased overall during the intervention and more with CM compared to monitoring and was associated with abstinence across conditions through follow-up. CONCLUSIONS CM improved some measures of response to smoking treatment in residential SUD patients.

Abstract
Background Even after quitting illicit drugs, tobacco abuse remains a major cause of morbidity and mortality in former injection drug users. An important unmet need in this population is to have effective interventions that can be used in the context of community based care. Contingency management, where a patient receives a monetary incentive for healthy behavior choices, and incorporation of individual counseling regarding spirometric “lung age” (the age of an average healthy individual with similar spirometry) have been shown to improve cessation rates in some populations. The efficacy of these interventions on improving smoking cessation rates has not been studied among current and former injection drug users. Methods In a randomized, factorial design study, we recruited 100 active smokers from an ongoing cohort study of current and former injection drug users to assess the impact of contingency management and spirometric lung age on smoking cessation. The primary outcome was 6-month biologically-confirmed smoking cessation comparing contingency management, spirometric lung age or both to usual care. Secondary outcomes included differences in self-reported and biologically-confirmed cessation at interim visits, number of visits attended and quit attempts, smoking rates at interim visits, and changes in Fagerstrom score and self-efficacy. Results Six-month biologically-confirmed smoking cessations rates were 4% usual care, 0% lung age, 14% contingency management and 0% for combined lung age and contingency management (p = 0.13). There were no differences in secondary endpoints comparing the four interventions or when pooling the lung age groups. Comparing contingency management to non-contingency management, 6-month cessation rates were not different (7% vs. 2%; p = 0.36), but total number of visits with exhaled carbon monoxide-confirmed abstinence were higher for contingency management than non-contingency management participants (0.38 vs. 0.06; p = 0.03), and more contingency management participants showed reduction in their Fagerstrom score from baseline to follow-up (39% vs. 18%; p = 0.03). Conclusions While lung age appeared ineffective, contingency management was associated with more short-term abstinence and lowered nicotine addiction. Contingency management may be a useful tool in development of effective tobacco cessation strategies among current and former injection drug users. Trial registration Clinicaltrials.gov

Abstract
BACKGROUND Contingency management (CM) is an efficacious intervention for reducing cigarette smoking. However, CM is rarely adopted as a smoking cessation treatment in the community. This study analyzed the effectiveness of a CM procedure in combination with a cognitive-behavioral treatment (CBT) for smoking cessation among treatment-seeking patients from the general population. METHODS A total of 92 patients were randomly assigned to one of two treatment conditions: CBT (N=49) or CBT+CM (N=43). The CM procedure included a voucher program through which nicotine abstinence was reinforced on a schedule of escalating magnitude of reinforcement with a reset contingency. Self-reported smoking status was confirmed with both carbon monoxide (CO) level in expired air and cotinine levels in urine. RESULTS Of the patients who received CBT+CM 97.7%, completed 6 weeks of treatment, versus 81.6% of those who received CBT (p=.03). At the post-treatment assessment, 95.3% of the patients assigned to the CBT+CM condition achieved abstinence in comparison to the 59.2% in the CBT group (p=.000). At the one-month follow-up, 72.1% of the patients who received CBT+CM maintained smoking abstinence, versus 34.7% in the CBT group (p=.001). At the six-month follow-up, 51.2% of the patients who received CBT+CM maintained smoking abstinence in comparison to the 28.6% in the CBT group (p=.04). CONCLUSIONS Results from this randomized clinical trial showed that adding CM to a CBT is effective, and is feasible as an intervention approach with treatment-seeking patients in a community setting.

Abstract
AbstractTobacco dependence is the most common substance use disorder in adults with mental illness. The prevalence rates for tobacco dependence are two to four times higher in these patients than in the general population. Smoking has a strong, negative influence on the life expectancy and quality of life of mental health patients, and remains the leading preventable cause of death in this group. Despite these statistics, in some countries smokers with mental illness are disadvantaged in receiving intervention and support for their tobacco dependence, which is often overlooked or even tolerated. This statement from the European Psychiatric Association (EPA) systematically reviews the current evidence on tobacco dependence and withdrawal in patients with mental illness and their treatment. It provides seven recommendations for the core components of diagnostics and treatment in this patient group. These recommendations concern: (1) the recording process, (2) the timing of the intervention, (3) counselling specificities, (4) proposed treatments, (5) frequency of contact after stopping, (6) follow-up visits and (7) relapse prevention. They aim to help clinicians improve the care, health and well-being of patients suffering from mental illness.

Abstract
INTRODUCTION Smokers with posttraumatic stress disorder (PTSD) smoke at higher prevalence rates and are more likely to relapse early in a quit attempt. Innovative methods are needed to enhance quit rates, particularly in the early quit period. Web-based contingency-management (CM) approaches have been found helpful in reducing smoking among other difficult-to-treat smoker populations but are limited by the need for computers. This pilot study builds on the web-based CM approach by evaluating a smartphone-based application for CM named mobile CM (mCM). METHODS Following a 2-week training period, 22 smokers with PTSD were randomized to a 4-week mCM condition or a yoked (i.e., noncontingent 4-week mCM condition). All smokers received 2 smoking cessation counseling sessions, nicotine replacement, and bupropion. Participants could earn up to $690 ($530 for mCM, $25.00 for assessments and office visits [up to 5], and $35.00 for equipment return). The average earned was $314.00. RESULTS Compliance was high during the 2-week training period (i.e., transmission of videos) (93%) and the 4-week treatment period (92%). Compliance rates did not differ by group assignment. Four-week quit rates (verified with CO) were 82% for the mCM and 45% for the yoked controls. Three-month self-report quit rates were 50% in the mCM and 18% in the yoked controls. CONCLUSIONS mCM may be a useful adjunctive smoking cessation treatment component for reducing smoking among smokers with PTSD, particularly early in a smoking quit attempt.

Abstract
In contingency management (CM), monetary incentives are contingent on evidence of drug abstinence. Typically, incentives (e.g., "vouchers" exchangeable for goods or services) are contingent on individual performance. We programmed vouchers contingent on group performance to investigate whether these contingencies would promote brief abstinence from cigarette smoking. Thirty-two participants were divided into small teams (n = 3 per team). During three 5-day within-subject experimental conditions, participants submitted video recordings of breath carbon monoxide (CO) measures twice daily via Motiv8 Systems, an Internet-based remote monitoring application. During the interdependent contingency condition, participants earned vouchers each time they and their teammates submitted breath CO samples indicative of abstinence (i.e., negative samples). During the independent contingency condition, participants earned vouchers each time they submitted negative samples, regardless of their teammates' performance. During the no vouchers condition, no monetary incentives were contingent on abstinence. In addition, half of the participants (n = 16) could communicate with their teammates through an online peer support forum. Although forum access did not appear to promote smoking abstinence, monetary incentives did promote brief abstinence. Significantly more negative samples were submitted when vouchers were contingent on individual performance (56%) or team performance (53%) relative to when no vouchers were available (35%; F = 6.9, p = .002). The results show that interdependent contingencies can promote brief abstinence from cigarette smoking. Moreover, the results suggest that these contingencies may help lower treatment costs and promote social support.

Abstract
Although applied behavior analysts often say they engage in evidence-based practice, they express differing views on what constitutes "evidence" and "practice." This article describes a practice as a service offered by a provider to help solve a problem presented by a consumer. Solving most problems (e.g., increasing or decreasing a behavior and maintaining this change) requires multiple intervention procedures (i.e., a package). Single-subject studies are invaluable in investigating individual procedures, but researchers still need to integrate the procedures into a package. The package must be standardized enough for independent providers to replicate yet flexible enough to allow individualization; intervention manuals are the primary technology for achieving this balance. To test whether the package is effective in solving consumers' problems, researchers must evaluate outcomes of the package as a whole, usually in group studies such as randomized controlled trials. From this perspective, establishing an evidence-based practice involves more than analyzing the effects of discrete intervention procedures on behavior; it requires synthesizing information so as to offer thorough solutions to problems. Recognizing the need for synthesis offers behavior analysts many promising opportunities to build on their existing research to increase the quality and quantity of evidence-based practices.

Abstract
OBJECTIVE Cigarette smoking is the leading cause of preventable death in the United States and world. Despite the availability of numerous therapies for smoking cessation, additional efficacious interventions are greatly needed. We provide a narrative review of published studies evaluating financial incentives for smoking cessation and discuss the parameters important for ensuring the efficacy of incentive interventions for smoking cessation. METHODS Published studies that evaluated the impact of incentives to promote smoking cessation and included an appropriate control or comparison condition were identified and reviewed. RESULTS Incentives are efficacious for promoting smoking abstinence across the general population of smokers as well as substance abusers, adolescents, patients with pulmonary disease, patients with serious mental illness and other challenging subgroups. To develop and implement an effective incentive treatment for smoking, special attention should be paid to biochemical verification of smoking status, incentive magnitude and the schedule of incentive delivery. CONCLUSION Consistent with the extensive literature showing that incentives are effective in reducing illicit drug use, a large body of evidence supports their effectiveness in reducing smoking. Continued efforts are warranted to further develop and disseminate incentive-based treatments for smoking cessation across clinical settings and populations.

Abstract
BACKGROUND In contingency management (CM) interventions, monetary consequences are contingent on evidence of drug abstinence. Typically, these consequences are contingent on individual performance. Consequences contingent on group performance may promote social support (e.g., praise). METHODS Thus, to combine social support with the monetary incentives of CM, we integrated independent and interdependent group contingencies of reinforcement into an Internet-based intervention to promote smoking abstinence. Breath carbon monoxide (CO) measures were compared between treatment conditions and a baseline control condition. Thirteen participants were divided into 5 groups or "teams" (n=2-3 per team). Each participant submitted video recordings of CO measurement twice daily via the Internet. Teammates could monitor each other's progress and communicate with one another through an online peer support forum. During a 4-day tapering condition, vouchers exchangeable for goods were contingent on gradual reductions in breath CO. During a 10-day abstinence induction condition, vouchers were contingent on abstinence (CO≤4ppm). In both treatment conditions, concurrent independent and interdependent group contingencies were arranged (i.e., a mixed contingency arrangement). RESULTS Less than 1% of CO samples submitted during baseline were≤4ppm, compared to 57% submitted during abstinence induction. Sixty-five percent of participants' comments on the online peer support forum were rated as positive by independent observers. Participants rated the intervention favorably on a treatment acceptability questionnaire. CONCLUSION The results suggest that the intervention is feasible and acceptable for promoting abstinence from cigarette smoking.

Abstract
BACKGROUND Background Material or financial incentives may be used in an attempt to reinforce behaviour change, including smoking cessation. They have been widely used in workplace smoking cessation programmes, and to a lesser extent within community programmes. Public health initiatives in the UK are currently planning to deploy incentive schemes to change unhealthy behaviours. Quit and Win contests are the subject of a companion review. OBJECTIVES To determine whether competitions and incentives lead to higher long-term quit rates. We also set out to examine the relationship between incentives and participation rates. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Specialized Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. Search terms included incentive*, competition*, contest*, reward*, prize*, contingent payment*, deposit contract*. The most recent searches were in November 2010. SELECTION CRITERIA We considered randomized controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. DATA COLLECTION AND ANALYSIS Data were extracted by one author (KC) and checked by the second (RP). We contacted study authors for additional data where necessary. The main outcome measure was abstinence from smoking at least six months from the start of the intervention. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Where possible we performed meta-analysis using a generic inverse variance model, grouped by timed endpoints, but not pooled across the subgroups. MAIN RESULTS Nineteen studies met our inclusion criteria, covering >4500 participants. Only one study, the largest in our review and covering 878 smokers, demonstrated significantly higher quit rates for the incentives group than for the control group beyond the six-month assessment. This trial referred its participants to local smoking cessation services, and offered substantial cash payments (up to US$750) for prolonged abstinence. In the remaining trials, there was no clear evidence that participants who committed their own money to the programme did better than those who did not, or that contingent rewards enhanced success rates over fixed payment schedules. There is some evidence that recruitment rates can be improved by rewarding participation, which may be expected to deliver higher absolute numbers of successful quitters. Cost effectiveness analysis was not appropriate to this review, since the efficacy of most of the interventions was not demonstrated. AUTHORS' CONCLUSIONS With the exception of one recent trial, incentives and competitions have not been shown to enhance long-term cessation rates. Early success tended to dissipate when the rewards were no longer offered. Rewarding participation and compliance in contests and cessation programmes may have potential to deliver higher absolute numbers of quitters. The one trial that achieved sustained success rates beyond the reward schedule concentrated its resources into substantial cash payments for abstinence rather than into running its own smoking cessation programme. Such an approach may only be feasible where independently-funded smoking cessation programmes are already available. Future research might explore the scale and longevity of possible cash reward schedules, within a variety of smoking populations.

Abstract
Cigarette smoking is highly prevalent among patients who are being treated for opioid-dependence, yet there have been limited scientific efforts to promote smoking cessation in this population. Contingency management (CM) is a behavioral treatment that provides monetary incentives contingent upon biochemical evidence of drug abstinence. This paper discusses the results of two studies that utilized CM to promote brief smoking cessation among opioid-maintained patients. Participants in a pilot study were randomly assigned for a 2-week period to a Contingent group that earned monetary vouchers for providing biochemical samples that met criteria for smoking abstinence, or a Noncontingent group that earned monetary vouchers independent of smoking status (Dunn et al., 2008). Results showed Contingent participants provided significantly more smoking-negative samples than Noncontingent participants (55% vs. 5%, respectively). A second randomized trial that utilized the same 2-week intervention and provided access to the smoking cessation pharmacotherapy bupropion replicated the results of the pilot study (55% and 17% abstinence in Contingent and Noncontingent groups, respectively; Dunn et al, 2010). Relapse to illicit drug use was also evaluated prospectively and no association between smoking abstinence and relapse to illicit drug use was observed (Dunn et al., 2009). It will be important for future studies to evaluate participant characteristics that might predict better treatment outcome, to assess the contribution that pharmacotherapies might have alone or in combination with a CM intervention on smoking cessation and to evaluate methods for maintaining the abstinence that is achieved during this brief intervention for longer periods of time.

Abstract
There is growing interest in using patient-directed incentives to change health-related behaviors. Advocates of incentive programs have proposed an ambitious research agenda for moving patient incentive programs forward. The unique cognitive and psychological features of older adults, however, present a challenge to this agenda. In particular, age-related changes in emotional regulation, executive function, and cognitive capacities, and a preference for collaborative decision-making raise questions about the suitability of these programs, particularly the structure of current financial incentives, for older adults. Differences in decision-making in older adults need to be accounted for in the design and implementation of financial incentive programs. Financial incentive programs adjusted to characteristics of older adult populations may be more likely to improve the lives of older persons and the economic success of programs that serve them.

Abstract
Individuals with attention deficit hyperactivity disorder (ADHD) smoke at rates significantly higher than the general population and have more difficulty quitting than nondiagnosed individuals. Currently, there are no evidence-based approaches for reducing smoking specifically in individuals with ADHD. Adult regular smokers with or without ADHD participated in a study of extended smoking withdrawal where monetary incentives were used to promote abstinence. Participants were paid according to an escalating schedule for maintaining abstinence measured as self-report of no smoking and an expired air carbon monoxide (CO) level of <or=4 parts per million. Sixty-four percent (14/22) of smokers with ADHD and 50% (11/22) of smokers without ADHD maintained complete abstinence for the 2-week duration of the study. Twenty-two percent (5/22) and 9% (2/22) of smokers with ADHD and without ADHD, respectively, maintained continued abstinence for up to 10 days following the removal of the contingencies. Though abstinence rates were higher for the smokers with ADHD, the group differences were not statistically significant. Results suggest that monetary incentives may be a useful approach for promoting abstinence in adult smokers with ADHD, perhaps owing to altered reinforcement processes in these individuals.

Abstract
Prevalence of cigarette smoking among opioid-maintained patients is more than threefold that of the general population and associated with increased morbidity and mortality. Relatively few studies have evaluated smoking interventions in this population. The purpose of the present study was to examine the efficacy of contingency management for promoting initial smoking abstinence. Forty methadone- or buprenorphine-maintained cigarette smokers were randomly assigned to a contingent (n = 20) or noncontingent (n = 20) experimental group and visited the clinic for 14 consecutive days. Contingent participants received vouchers based on breath carbon monoxide levels during Study Days 1 to 5 and urinary cotinine levels during Days 6 to 14. Voucher earnings began at $9.00 and increased by $1.50 with each subsequent negative sample for maximum possible of $362.50. Noncontingent participants earned vouchers independent of smoking status. Although not a primary focus, participants who were interested and medically eligible could also receive bupropion (Zyban). Contingent participants achieved significantly more initial smoking abstinence, as evidenced by a greater percentage of smoking-negative samples (55% vs. 17%) and longer duration of continuous abstinence (7.7 vs. 2.4 days) during the 2 week quit attempt than noncontingent participants, respectively. Bupropion did not significantly influence abstinence outcomes. Results from this randomized clinical trial support the efficacy of contingency management interventions in promoting initial smoking abstinence in this challenging population.

Abstract
RATIONALE Experimental research is needed in investigating how early smoking abstinence affects relapse risk. OBJECTIVE The present study assessed the feasibility of promoting smoking abstinence using once- rather than thrice-daily abstinence monitoring and the relationship between different durations of initial abstinence and changes in smoking preference. METHODS Participants were 34 adult smokers randomized into one of two conditions: 14-day (14C) and 1-day (1C) contingent payment for smoking abstinence. Smoking status and participant ratings were assessed daily; a delay discounting task involving hypothetical money and an inter-temporal choice task involving hypothetical money and cigarettes were administered at baseline and days 7 and 14; a direct test of preference for smoking versus money was assessed on day 14. RESULTS Once-daily monitoring gained robust experimental control over smoking abstinence. No differences in delay discounting for hypothetical money were observed between the two conditions. Compared to the 1C condition, participants in the 14C condition (1) showed significant increases in the mean percent of delayed hypothetical money over cigarettes choices in the inter-temporal choice task, (2) were significantly less likely to ever choose the smoking option in the direct test of preference for smoking versus money, and (3) reported greater ease of abstaining from smoking and lower nicotine withdrawal and craving. CONCLUSIONS These results offer a more efficient procedure for experimentally promoting smoking abstinence, while providing further evidence that an initial period of sustained abstinence produces a profile of changes consistent with an overall lowering of relapse risk.

Abstract
Opioid treatment program patients and staff often have concerns that smoking cessation may jeopardize abstinence from illicit drug use. In this study, we evaluated whether smoking abstinence produced with a two-week contingency-management (CM) intervention was associated with relapse to illicit drug use among patients enrolled in opioid maintenance. Opioid-maintenance patients who were stable in treatment and abstinent from illicit drugs were enrolled in a 14-day smoking-cessation study. Participants were dichotomized into Abstainers (> 90% smoking-negative samples, n=12) and Smokers (< 10% smoking-negative samples, n=16). Illicit drug assays included opioids, oxycodone, propoxyphene, cannabis, amphetamines, cocaine and benzodiazepines. There were no differences between the Abstainers and Smokers, with 99% and 96% of samples testing negative for all illicit drugs in each group, respectively. Data from this study provide no evidence that smoking cessation among stable opioid-maintained patients undermines drug abstinence and lend support for programs that encourage smoking cessation during drug abuse treatment.

Abstract
Extensive evidence from the laboratory and the clinic suggests that drug addiction can be viewed as operant behavior and effectively treated through the application of principles of operant conditioning. Contingency management interventions that arrange for the direct reinforcement of drug abstinence or of other therapeutically important target behaviors (e.g., regular use of drug abuse treatment medications) are among the most studied type of operant treatments. Behavior analysts have contributed to the substantial and rapidly growing literature on operant treatments for drug addiction, but the publications of this work usually appear in medical, clinical psychology, or drug abuse journals. This special issue of the Journal of Applied Behavior Analysis represents an effort to bring this important work to the attention of the behavior-analytic community. The articles in this special issue illustrate both the enormous potential of contingency management interventions to address the serious and seemingly intractable problem of drug addiction as well as the real challenges involved in attempting to develop and disseminate treatments that will produce substantial and lasting changes in the lives of individuals plagued by the chronic problem of drug addiction.

Abstract
Fifty-eight smokers received abstinence-contingent monetary payments for 1 (n=15) or 14 (n=3) days. Those who received contingent payments for 14 days also received 0, 1, or 8 experimenter-delivered cigarette puffs on 5 evenings. The relative reinforcing effects of smoking were assessed in a 3-hr session on the final study day, when participants made 20 choices between smoking or money. The reinforcement contingencies exerted robust control over smoking, and programmed smoking lapses produced few discernible effects. These results further illustrate the robust control that reinforcement contingencies can exert over cigarette smoking and suggest that any effects of lapses on the relative reinforcing effects of smoking are modest under conditions involving abstinence-contingent reinforcement contingencies.
