Abstract
INTRODUCTION AND AIMS Tranquilizer use is associated with negative health outcomes among people who use drugs. This paper aims to estimate the incidence rate (initiation) and identify predictors of tranquilizer misuse (TM) among cocaine users. DESIGN AND METHODS A prospective cohort study was conducted in Montreal, Canada. Interviewer-administered questionnaires were carried out at 3-month intervals. Initiation was defined as misusing a tranquilizer for the first time during follow-up. 'Lasting-initiation', defined as reporting TM at the next visit following first use, was also examined. Cox proportional hazard regression analyses were carried out to assess predictors of initiation to TM. RESULTS Among the 245 participants who were eligible for the initiation analyses, 123 started TM during follow-up for an incidence rate of 40.49 per 100 person-years (95% confidence interval, CI: 33.80-48.15). Of the 123 initiates, 35.7% were still using at the interview following initiation for an incidence rate of 14.70 per 100 person-years (95% CI: 10.82-19.56). Multivariate models showed that independent predictors of initiation and 'lasting initiation' were identical as having had a criminal activity as the main source of income, having been recently in treatment for a substance use disorder (SUD) and reporting non-medical use of prescription opioids. DISCUSSION AND CONCLUSIONS The incidence rate of TM initiation was high among a sample of cocaine users. Initiation was predicted by a problematic drug use pattern involving polydrug use, involvement in the street economy and having been in treatment for a SUD. These findings have implications for prevention and harm reduction strategies.

Abstract
BACKGROUND Benzodiazepines (BZDs) have a sedative and hypnotic effect upon people. Short term use can be beneficial but long term BZD use is common, with several risks in addition to the potential for dependence in both opiate and non-opiate dependent patients. OBJECTIVES To evaluate the effectiveness of psychosocial interventions for treating BZD harmful use, abuse or dependence compared to pharmacological interventions, no intervention, placebo or a different psychosocial intervention on reducing the use of BZDs in opiate dependent and non-opiate dependent groups. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL- the Cochrane Library issue 12, 2014) which includes the Cochrane Drugs and Alcohol Group Specialized Register; PubMed (from 1966 to December 2014); EMBASE (from 1988 to December 2014); CINAHL Cumulative Index to Nursing and AlliedHealth Literature (1982 to September 2013); PsychINFO (1872 to December 2014); ERIC (Education Resources Information Centre, (January 1966 to September 2013); All EBM Reviews (1991 to September 2013, Ovid Interface); AMED (Allied & Alternative Medicine) 1985 to September 2013); ASSIA (Applied Social Sciences Index & Abstracts (1960 to September 2013); LILACS (January 1982 to September 2013);Web of Science (1900 to December 2014);Electronic Grey Literature Databases: Dissertation Abstract; Index to Theses. SELECTION CRITERIA Randomised controlled trials examining the use of a psychosocial intervention to treat BZDs versus pharmacological interventions,no intervention, placebo or a different psychosocial intervention on reducing the use of BZDs in opiate dependent and non-opiate dependent groups. DATA COLLECTION AND ANALYSIS We used the standard methodological procedures outlined in Cochrane Guidelines. MAIN RESULTS Twenty-five studies including 1666 people met the inclusion criteria. The studies tested many different psychosocial interventions including cognitive behavioural therapy (CBT) (some studies with taper, other studies with no taper), motivational interviewing (MI),letters to patients advising them to reduce or quit BZD use, relaxation studies, counselling delivered electronically and advice provided by a general practitioner (GP). Based on the data obtained, we performed two meta-analyses in this Cochrane review: one assessing the effectiveness of CBT plus taper versus taper only (575 participants), and one assessing MI versus treatment as usual (TAU) (80 participants).There was moderate quality of evidence that CBT plus taper was more likely to result in successful discontinuation of BZDs within four weeks post treatment compared to taper only (Risk ratio (RR) 1.40, 95% confidence interval (CI) 1.05 to 1.86; nine trials, 423 participants) and moderate quality of evidence at three month follow-up (RR 1.51, 95% CI 1.15 to 1.98) in favour of CBT (taper)for 575 participants. The effects were less certain at 6, 11, 12, 15 and 24 months follow-up. The effect of CBT on reducing BZDs by> 50% was uncertain for all time points examined due to the low quality evidence. There was very low quality evidence for the effect on drop-outs at any of the time intervals; post-treatment (RR 1.05, 95% CI 0.66 to 1.66), three month follow-up (RR 1.71, 95% CI0.16 to 17.98) and six month follow-up (RR 0.70, 95% CI 0.17 to 2.88).Based on the very low quality of evidence available, the effect of MI versus TAU for all the time intervals is unclear; post treatment(RR 4.43, 95% CI 0.16 to 125.35; two trials, 34 participants), at three month follow-up (RR 3.46, 95% CI 0.53 to 22.45; four trials,80 participants), six month follow-up (RR 0.14, 95% CI 0.01 to 1.89) and 12 month follow-up (RR 1.25, 95% CI 0.63 to 2.47).There was very low quality of evidence to determine the effect of MI on reducing BZDs by > 50% at three month follow-up (RR 1.52,95% CI 0.60 to 3.83) and 12 month follow-up (RR 0.87, 95% CI 0.52 to 1.47). The effects on drop-outs from treatment at any of e time intervals between the two groups were uncertain due to the wide CIs; post-treatment (RR 0.50, 95% CI 0.04 to 7.10), three month follow-up (RR 0.46, 95% CI 0.06 to 3.28), six month follow-up (RR 8.75, 95% CI 0.61 to 124.53) and 12 month follow-up(RR 0.42, 95% CI 0.02 to 7.71).The following interventions reduced BZD use - tailored GP letter versus generic GP letter at 12 month follow-up (RR 1.70, 95%CI 1.07 to 2.70; one trial, 322 participants), standardised interview versus TAU at six month follow-up (RR 13.11, 95% CI 3.25 to 52.83; one trial, 139 participants) and 12 month follow-up (RR 4.97, 95% CI 2.23 to 11.11), and relaxation versus TAU at three month follow-up (RR 2.20, 95% CI 1.23 to 3.94).There was insufficient supporting evidence for the remaining interventions.We performed a 'Risk of bias' assessment on all included studies. We assessed the quality of the evidence as high quality for random sequence generation, attrition bias and reporting bias; moderate quality for allocation concealment, performance bias for objective outcomes, and detection bias for objective outcomes; and low quality for performance bias for subjective outcomes and detection bias for subjective outcomes. Few studies had manualised sessions or independent tests of treatment fidelity; most follow-up periods were less than 12 months.Based on decisions made during the implementation of protocol methods to present a manageable summary of the evidence we did not collect data on quality of life, self-harm or adverse events. AUTHORS' CONCLUSIONS CBT plus taper is effective in the short term (three month time period) in reducing BZD use. However, this is not sustained at six months and subsequently. Currently there is insufficient evidence to support the use of MI to reduce BZD use. There is emerging evidence to suggest that a tailored GP letter versus a generic GP letter, a standardised interview versus TAU, and relaxation versus TAU could be effective for BZD reduction. There is currently insufficient evidence for other approaches to reduce BZD use.

Abstract
The psychiatric care of opioid users receiving agonist therapies is often complicated by high rates of illicit drug use (Brooner et al., 2013). The present study evaluates if illicit drug use (i.e., opioids, cocaine, sedatives) detected at the start of psychiatric care affects treatment response. Methadone maintenance patients (n = 125) with at least one current psychiatric disorder completed a 3-month randomized clinical trial evaluating the efficacy of financial incentives on attendance to on-site integrated substance abuse and psychiatric services (Kidorf et al., 2013). The present study re-analyzes the data set by grouping participants into one of two conditions based on the 4-week baseline observation: (1) no illicit drug use (baseline negative; n = 50), or (2) any illicit drug use (baseline positive; n = 75). All participants received a similar schedule of psychiatric services, and had good access to prescribed psychiatric medications. The Global Severity Index (GSI) of the Hopkins Symptom Checklist-Revised was administered monthly to evaluate changes in psychiatric distress. Results showed that while both conditions evidenced similar utilization of on-site psychiatric services, baseline negative participants remained in treatment somewhat longer (80.7 vs. 74.8 days, p = .04) and demonstrated greater reductions in GSI scores than baseline positive participants at month 3 (p = .004). These results have implications for interpreting previous studies that have shown inconsistent efficacy of pharmacotherapy and other psychiatric treatments, and for providing clinical care for patients with co-occurring substance use and psychiatric disorders.

Abstract
We conducted a cross-sectional study investigating the extent of addictive disorders within a workers' compensation (WC) clinic. We also examined the feasibility of substance abuse screening within the same clinic. In 2009 , 100 patients were asked to complete the World Health Organization's Alcohol, Smoking, Substance Involvement Screening Test (WHO-ASSIST) and the Current Opioid Misuse Measure (COMM). According to the WHO-ASSIST, we found that 46% of WC patients required intervention for at least one substance-related disorder (25% tobacco, 23% sedatives, 8% opioids), and according to the COMM, 46% screened positive for prescription opioid misuse. Importantly, the addition of this screening was brief, economical, and well accepted by patients. Further research should analyze the costs and benefits of detection and intervention of substance-related disorders in this setting.

Abstract
OBJECTIVE Cross-sectional studies show that considerable proportions of opiate dependents in methadone maintenance treatment (MMT) consume benzodiazepines (BZD). The longitudinal patterns of BZD use over time were described here. METHODS After admission to MMT, patients from two outpatient MMT clinics (n = 345) were observed for up to 2 years whilst in treatment. The use of BZD, cannabis, opiates and cocaine was assessed by urine sampling carried out twice a month. RESULTS For the whole sample, the mean BZD-positive urine specimen rate was 0.36 during the first 3 months. Rates slightly decreased during the first year and remained stable afterwards (last observation carried forward). For study completers (n = 152), the rate decreased over time, from 0.31 (first 3-month period) to 0.19 (last period; p < 0.001). According to a longitudinal cluster analysis, 26% of all patients showed a pattern of constantly high BZD-positivity rates, mostly in combination with other substances. Inpatient detoxifications from BZD (carried out in 18% of cases) did not have a sustained effect on levels of BZD use. CONCLUSIONS BZD consumption in MMT is often part of a polydrug consumption pattern and is associated with poorer treatment retention. It is necessary to further investigate the reasons for BZD use in MMT patients and to develop effective interventions to reduce levels of BZD consumption.

Abstract
OBJECTIVE We sought to investigate the association between chronic pain and self-reported prescription drug abuse in a large cohort of patients referred from primary care for a behavioral health assessment. DESIGN We performed a cross-sectional analysis of responses to a telephone assessment administered to patients referred for a behavioral health evaluation between April 25, 2005 and October 31, 2007. We conducted descriptive statistics and investigated multivariable associations. Multivariable analyses included age, gender, race, financial status, employment, current smoking, drinking problem, past-year illicit drug use, depression, and chronic pain. PATIENTS Veterans referred from primary care (N = 6,377). RESULTS Mean age of the sample was 56.5 years with a range of 19-97. The majority of respondents was white, unmarried, and was unemployed. Nearly 5% of the sample reported past 6-month prescription drug abuse. On multivariable analysis, younger age, possible depression (odds ratio [OR] 1.9; 1.3-2.8), probable depression (OR 2.4; 1.6-3.4), smoking (OR 1.4; 1.1-1.8), illicit drug use (OR 2.8; 2.2-3.7), and chronic pain (OR 1.9; 1.4-2.5) were associated with prescription drug abuse. CONCLUSIONS We have identified specific variables associated with self-reported prescription drug abuse in primary care patients. Chronic pain is associated both with an indication for prescribing opioids and with abuse of prescription medications. Clinicians are encouraged to follow treatment algorithms when managing patients with chronic pain as a method for reducing misuse.

Abstract
The relations among psychiatric and substance dependence disorders and treatment utilization are of interest both for their clinical management and for health services. We examined these relations using six self-reported indices of cocaine dependence severity and three self-reported measures of treatment utilization and self-help group participation for cocaine dependence. The sample consisted of dyads: namely, a cocaine-dependent adult proband (N=449) and a cocaine-dependent sibling (N=449). Psychiatric and substance use disorders were assessed with the Semi-structured Assessment for Drug Dependence and Alcoholism. We controlled for the nesting within families of proband-sibling dyads and for demographic features using generalized estimating equation linear and logistic regression analyses. We found that psychiatric disorders were associated with an increased likelihood of cocaine dependence treatment or self-help group participation, but with only one of six indices of cocaine dependence severity. Bipolar disorder and antisocial personality disorder were associated with greater past heavy cocaine use, and with utilizing self-help but not treatment. Major depressive disorder and posttraumatic stress disorder were associated with treatment utilization and overall services utilization, respectively. The presence of other substance use disorders (SUDs) was the strongest correlate of cocaine dependence severity. Results suggest that co-occurring substance dependence and psychiatric disorders warrant attention in cocaine dependence assessment, treatment, and self-help.

Abstract
The purposes of this study were to examine predictors of benzodiazepine use among methadone maintenance treatment patients, to determine whether baseline benzodiazepine use influenced ongoing use during methadone maintenance treatment, and to assess the effect of ongoing benzodiazepine use on treatment outcomes (i.e., opioid and cocaine use and treatment retention). A retrospective chart review of 172 methadone maintenance treatment patients (mean age = 34.6 years; standard deviation = 8.5 years; 64% male) from January 1997 to December 1999 was conducted. At baseline, 29% were "non-users" (past year) of benzodiazepine, 36% were "occasional users," and 35% were "regular/problem users." Regular/problem users were more likely to have started opioid use with prescription opioids, experienced more overdoses, and reported psychiatric comorbidity. Being female, more years of opioid use, and a history of psychiatric treatment were significant predictors of baseline benzodiazepine use. Ongoing benzodiazepine users were more likely to have opioid-positive and cocaine-positive urine screens during methadone maintenance treatment. Only ongoing cocaine use was negatively related to retention. Benzodiazepine use by methadone maintenance treatment patients is associated with a more complex clinical picture and may negatively influence treatment outcomes.

Abstract
The relationship between pre-treatment illicit benzodiazepine use (days of use in the last 30) assessed on the Addiction Severity Index (ASI) and treatment outcome was investigated by retrospective analysis of data from two controlled clinical trials in 361 methadone maintained cocaine/opiate users randomly assigned to 12-week voucher- or prize-based contingency management (CM) or control interventions. Based on screening ASI, participants were identified as non-users (BZD-N; 0 days of use) or users (BZD-U; >0 days of use). Outcome measures were: urine drug screens (thrice weekly); quality of life and self-reported HIV-risk behaviors (every 2 weeks); and current DSM-IV diagnosis of cocaine and heroin dependence (study exit). In the CM group, BZD-U had significantly worse outcomes on in-treatment cocaine use, quality-of-life scores, needle-sharing behaviors, and current heroin dependence diagnoses at study exit compared to BZD-N. In the control group, BZD-U had significantly higher in-treatment cocaine use but did not differ from BZD-N on psychosocial measures. Thus, in a sample of non-dependent BZD users, self-reported illicit BZD use on the ASI, even at low levels, predicted worse outcome on cocaine use and blunted response to CM.

Abstract
BACKGROUND The purpose of this study was to examine whether rural inhabitants were more likely than urban inhabitants to meet the criteria for comorbid mental health and substance abuse or dependence disorders. METHODS Data were from the National Comorbidity Survey, and included 5185 (532=rural; 4653=urban) persons age 14-54 years of age who were interviewed using the Composite International Diagnostic Interview (CIDI). Logistic regression that accounted for the complex survey data and weighting scheme was utilized. RESULTS Participants residing in rural areas were more likely to meet the DSM-III-R criteria for past month alcohol abuse or dependence if they also met the diagnostic criteria for past month major depressive disorder (MDD) or lifetime antisocial personality disorder (ASPD), adjusting for age, race, gender, education and income. Similarly, rural participants were more likely to meet the criteria for comorbid drug abuse or dependence in the past month if they met the diagnosis for either past month MDD, generalized anxiety disorder or lifetime ASPD, controlling for demographic characteristics. Rural residents with any current mental disorder also were less likely to seek treatment than their urban counterparts. LIMITATIONS Data were collected in 1991 and do not capture changes in prevalence of comorbidities. Also, the small number of rural residents sampled resulted in small cell sizes for some comorbidities. CONCLUSIONS Rural residents were significantly more likely to meet the criteria for substance disorders given they also met the criteria for a mental disorder, and those with any current mental disorder were less likely to seek treatment. Since the overall prevalence of these disorders does not differ between rural and urban inhabitants, findings suggest that rural persons may lack access to adequate treatment for their mental health disorders and subsequently may be self-medicating with alcohol and/or drugs.

Abstract
The present study evaluated the effects of psychiatric comorbidity on substance use disorder prevalence, HIV risk behavior, and other problem severity in male and female out-of-treatment injection drug users newly registered at a syringe exchange program. Participants (N = 338) were administered the Structured Clinical Interview for the DSM-IV, the Addiction Severity Index, and the Risk Assessment Battery, and classified into one of four diagnostic groups: (1) no antisocial personality disorder (APD) or Axis I psychiatric disorder (N = 162), (2) APD only (N = 74), (3) Axis I psychiatric disorder only (N = 55), or (4) APD plus Axis I psychiatric disorder (N = 47). Psychiatric comorbidity was associated with higher rates of substance use disorder and more HIV risk and other problem severity. In general, participants with both APD and an Axis I disorder exhibited the most problem severity. APD was uniquely associated with higher prevalence for each substance use disorder assessed in this study and with elevated HIV risk. These results support and extend studies conducted with opioid-dependent individuals recruited from treatment and community settings, and reinforce the need to develop interventions to encourage syringe exchange program participants to enroll in treatment.

Abstract
Concomitant consumption of benzodiazepines (BZDs) and opioids is a major problem in patients with opioid dependence. It may have substantial impact on morbidity, mortality and clinical course. The current retrospective study aims to determine whether there are differences in the additional use of BZDs among addicts regularly taking methadone or codeine medications in treatment and untreated addicts injecting heroin. The records of 1,685 patients admitted for detoxification were analyzed using bivariate analysis and multiple logistic regression analysis. Demographic and drug related variables were considered, both as possible confounders and predictors of concomitant BZD use. Daily intake of BZDs was reported in 44.4% of the patients. Patients treated with methadone or codeine medications report daily intake of BZDs significantly more often than the heroin-dependent patients (p < 0.01). Using multiple regression analyses, the results were confirmed as independent from the assessed possible confounders. Further we found that daily use of alcohol or barbiturates, early onset of opioid use (p < 0.01), unemployment, having a substance dependent family member with, and a history of imprisonment (for all p < 0.05) were associated with concomitant daily consumption of BZDs in opioid dependent subjects. These finding underline the need to further explore the causes, interactions and consequences of concomitant BZD and opiate use.

Abstract
This review of negative reinforcement models of drug dependence is part of a series that takes the position that a complete understanding of current concepts of dependence will facilitate the development of reliable and valid measures of the emergence of tobacco dependence. Other reviews within the series consider models that emphasize positive reinforcement and social learning/cognitive models. This review summarizes negative reinforcement in general and then presents four current negative reinforcement models that emphasize withdrawal, classical conditioning, self-medication and opponent-processes. For each model, the paper outlines central aspects of dependence, conceptualization of dependence development and influences that the model might have on current and future measures of dependence. Understanding how drug dependence develops will be an important part of future successful tobacco dependence measurement, prevention and treatment strategies.

Abstract
Knowledge about co-occurring personality disorders in drug users is important for planning therapy and prevention. The objective of this study was to assess whether the SCID-II (Structured Clinical Interview for DSM-III-R) Screen for antisocial personality disorder was feasible and acceptable in a population of opioid users. A qualitative study on veridicality and emotional quality in responses to SCID-II Screen was carried out by personal interview in a multifunctional addiction centre. The subjects were 10 outpatient participants (six female, four male) in methadone substitution treatment. The SCID-II Screen triggered a high level of emotions. Some questions were mainly interpreted from a victim's perspective, even though the intention was the perpetrator's view. Questions were seen as sex-biased. Provision of support to deal with potential emotional problems should be supplied. Potential revision should be considered to include the female perspective in the screen.

Abstract
Relatively little is known about the prevalence and clinical characteristics of dependence on sedative-hypnotics, and almost nothing has been published regarding abuse. This report relates information on Diagnostic and Statistical Manual of the American Psychiatric Association (DSM-IIIR) sedative-hypnotic use disorders among subjects from the Collaborative Study on the Genetics of Alcoholism (COGA). A standardized interview was used to generate data on 407 men and women in Group 1 with sedative-hypnotic dependence (4.4% of the COGA sample), 34 in Group 2 with abuse (0.4%), and 3,426 comparison subjects in Group 3 with alcohol dependence in the absence of a sedative-hypnotic use disorder (36.7%). The remaining COGA subjects (48.5%) were not included as they had neither alcohol nor sedative-hypnotic dependence or abuse. Those with sedative-hypnotic abuse or dependence were more likely to be Caucasian individuals with abuse or dependence on marijuana, cocaine, amphetamines, or opioids. Subjects in Groups 1 and 2 were also more likely to have histories of independent major depressive and panic disorders, as well as substance-induced mood disorders. Those with dependence, compared to abuse, were likely to be women, reported staying intoxicated for a day or more, but noted less abuse of opioids or amphetamines, although Group 2 members also had high rates of difficulties with sedative-hypnotics. These results highlight notable rates of sedative-hypnotic dependence in the COGA families, and indicate that while sedative-hypnotic abuse does occur, and while the clinical course can involve relatively serious problems, it is less common than dependence.

Abstract
OBJECTIVE To determine the prevalence and correlates associated with sedative use and misuse in the general population. METHOD Data were drawn from the National Comobidity Survey (n = 8098), a representative sample of adults in the community. Multivariate logistic regression analyses were used to identify correlates of sedative use, non-prescription use and self-perceived dependence. RESULTS The life-time prevalence of self-perceived sedative dependence was 0.5%, 7.1% reported non-prescribed sedative use and 17.0% had been prescribed sedatives and denied misuse. Individuals who used sedatives without a prescription were more likely to be male (OR = 0.61 (0.44, 0.86)), have lower income (OR = 0.71 (0.54, 0.94)), more education (OR = 1.51 (1.17, 1.96)), major depression (OR = 1.47 (1.04, 2.08)), agoraphobia (OR = 1.59 (1.09, 2.32)), ASPD (OR = 5.29 (3.42, 8.20)) and suicide ideation (OR = 1.91 (1.23, 2.94)), compared with those who did not use sedatives. Individuals with self-perceived dependence on sedatives were older (OR = 1.05 (1.02, 1.08)), had less education (OR = 0.2 (0.1, 0.7)) and were more likely to have a parent who abused prescription medications (OR = 4.3 (1.03, 18.03)), compared with those without sedative dependence. CONCLUSIONS Almost one in 10 adults report misuse of sedatives in their lifetime. Sedative use and misuse are associated with high levels of psychopathology and suicide risk, and show a specific association with parental abuse of prescription medications in the general population. Future work to understand more effectively the nature of these associations may ultimately lead to improved effectiveness of preventive interventions.

Abstract
Patients with heroin dependence frequently present to internists and other physicians for heroin-related medical, psychiatric, and behavioral health problems and often seek help with reducing their heroin use. Thus, physicians should be familiar with the identification and diagnosis of heroin dependence in their patients and be able to initiate treatment of heroin dependence both directly and by referral. Recent research has provided much information concerning effective pharmacologically based treatment approaches for managing opioid withdrawal and helping patients to remain abstinent Methadone maintenance and newer approaches using L-alpha acetylmethadol and buprenorphine seem to be particularly effective in promoting relapse prevention. Although these treatments are currently provided in special drug treatment settings, recent and ongoing research indicates that the physician's office may be an effective alternative site for these treatments.

Abstract
This study examined the efficacy of a urinalysis-based contingency management program for preventing relapse to abused drugs following a brief residential detoxification. Fourteen methadone maintenance patients who were chronic benzodiazepine users were enrolled in a 7-day inpatient benzodiazepine detoxification and randomly assigned to receive Contingency Management (N = 7) or Standard Care (N = 7) therapy upon return to outpatient methadone treatment. In the Contingency Management condition, a methadone take-home dose or a US $25 voucher (patient's choice) could be earned for each urine sample submitted on a Monday, Wednesday or Friday that was free of opiates, cocaine and benzodiazepines. Data analysis and interpretation focused on within-group post-hoc differences due to group differences on employment and legal status, potentially confounding baseline variables. Repeated measures analysis of variance showed that Contingency Management patients submitted significantly more drug-free urine samples during the intervention compared to pre-detoxification (p < 0.01), whereas no significance changes were observed from pre- to post-detoxification in the Standard Care patients. Employment and legal status of patients may have facilitated response to contingency management procedures, but did not prevent relapse when contingency management procedures were withdrawn. Overall, these preliminary results suggest that abstinence-based contingency management is a promising strategy for preventing relapse to multiple drugs of abuse in a subset of methadone maintenance patients when abstinence has been initiated through brief inpatient treatment.
