Smoking prevalence in addiction treatment: a review

Examining the relationships between posttraumatic stress disorder symptoms, positive smoking outcome expectancies, and cigarette smoking in people with substance use disorders: a multiple mediator model

Cigarette smoking is highly prevalent in people with substance use disorders (SUDs) and is associated with significant physical health problems. Posttraumatic stress disorder (PTSD) is also highly associated with both SUDs and cigarette smoking and may serve as a barrier to smoking cessation efforts. In addition, people with PTSD are more likely to hold positive smoking outcome expectancies (i.e., beliefs that smoking cigarettes results in positive outcomes); these beliefs may contribute to cigarette smoking in people with SUDs experiencing PTSD symptoms. The present study examined the relationship between PTSD symptoms and typical daily cigarette smoking/cigarette dependence symptoms in a sample of 227 trauma-exposed current smokers with SUDs (59.9% male, 89.4% Caucasian) seeking detoxification treatment services. Additionally, the indirect effects of multiple types of positive smoking outcome expectancies on these relationships were examined. Participants completed questionnaires assessing PTSD symptoms, positive smoking outcome expectancies, cigarette consumption, and cigarette dependence symptoms. Results indicated that PTSD symptoms were not directly related to cigarette consumption or cigarette dependence symptoms. However, negative affect reduction outcome expectancies were shown to have a significant indirect effect between PTSD symptoms and cigarette consumption, while negative affect reduction, boredom reduction, and taste-sensorimotor manipulation outcome expectancies were all found to have significant indirect effects between PTSD symptoms and cigarette dependence symptoms. The indirect effect involving negative affect reduction outcome expectancies was statistically larger than that of taste sensorimotor manipulation outcome expectancies, while negative affect reduction and boredom reduction outcome expectancies were comparable in magnitude. These results suggest that expectancies that smoking can manage negative affective experiences are related to cigarette smoking in people with SUDs experiencing PTSD symptoms and suggest that effective smoking cessation treatments should take into account these expectancies.

Comparison of Caffeine and d-amphetamine in Cocaine-Dependent Subjects: Differential Outcomes on Subjective and Cardiovascular Effects, Reward Learning, and Salivary Paraxanthine

Due to indirect modulation of dopamine transmission, adenosine receptor antagonists may be useful in either treating cocaine use or improving disrupted cognitive-behavioral functions associated with chronic cocaine use. To compare and contrast the stimulant effects of adenosine antagonism to direct dopamine stimulation, we administered 150 mg and 300 mg caffeine, 20 mg amphetamine, and placebo to cocaine-dependent vs. healthy control subjects, matched on moderate caffeine use. Data were obtained on measures of cardiovascular effects, subjective drug effects (ARCI, VAS, DEQ), and a probabilistic reward-learning task sensitive to dopamine modulation. Levels of salivary caffeine and the primary caffeine metabolite paraxanthine were obtained on placebo and caffeine dosing days. Cardiovascular results revealed main effects of dose for diastolic blood pressure and heart rate; follow up tests showed that controls were most sensitive to 300 mg caffeine and 20 mg amphetamine; cocaine-dependent subjects were sensitive only to 300 mg caffeine. Subjective effects results revealed dose × time and dose × group interactions on the ARCI A, ARCI LSD, and VAS 'elated' scales; follow up tests did not show systematic differences between groups with regard to caffeine or d-amphetamine. Large between-group differences in salivary paraxanthine (but not salivary caffeine) levels were obtained under both caffeine doses. The cocaine-dependent group expressed significantly higher paraxanthine levels than controls under 150 mg and 3-4 fold greater levels under 300 mg at 90 min and 150 min post caffeine dose. However, these differences also covaried with cigarette smoking status (not balanced between groups), and nicotine smoking is known to alter caffeine/paraxanthine metabolism via cytochrome P450 enzymes. These preliminary data raise the possibility that adenosine antagonists may affect cocaine-dependent and non-dependent subjects differently. In conjunction with previous preclinical and human studies, the data suggest that adenosine modulating drugs may have value in the treatment of stimulant use disorders.

Climate for innovation, 12-step orientation, and tobacco cessation treatment

This study examined the relationship between (1) three indicators of climate for innovation (clinician skills, absence of program obstacles, policy-related incentives) and adoption extensiveness of both behavioral treatments for tobacco cessation (TC) and system-level support for TC in substance use disorder treatment programs, (2) a program's 12-step treatment orientation and adoption extensiveness, and (3) whether 12-step treatment orientation moderates the relationship between climate for innovation and adoption extensiveness. Data were obtained from a random sample of 1006 program administrators. Hierarchical regression results showed that both absence of program obstacles and policy-related incentives are positively related to adoption extensiveness. Twelve-step treatment orientation is neither related to adoption extensiveness nor a moderator of the relationship between climate for innovation and adoption extensiveness. Although the adoption of both behavioral treatments for TC and system-level support for TC is not extensive, we conclude that a 12-step treatment orientation neither hampers nor promotes adoption extensiveness.

Expectancies for smoking cessation among drug-involved smokers: implications for clinical practice

Drug-involved smokers may be less motivated to quit smoking because they expect smoking cessation to occasion adverse outcomes (e.g., exacerbation of drug use). Non-treatment-seeking adult smokers from the community (N=507) reported drug involvement, expectancies for smoking abstinence via the Smoking Abstinence Questionnaire (SAQ), and motivation to quit smoking (desire to quit and abstinence goal). Mediation analyses evaluated the indirect effects of binge drinking, marijuana, cocaine, other stimulant, opiate, and barbiturate/other sedative involvement on motivation to quit smoking through the SAQ Adverse Outcomes scale. Adverse outcomes expectancies accounted for a reduced desire to quit smoking and a lower likelihood of endorsing a goal of complete smoking abstinence among those involved with binge drinking, marijuana, cocaine, other stimulants, opiates, and barbiturates/other sedatives. Drug-involved smokers' greater expectancies for adverse outcomes upon quitting smoking may deter smoking quit attempts. Interventions are encouraged to counteract the notion that smoking cessation jeopardizes sobriety.

The prevalence and correlates of single cigarette selling among urban disadvantaged drug users in Baltimore, Maryland

BACKGROUND

Selling of single cigarettes, also known as loosies, is a public health concern. Loosies allow for those with fewer resources to buy cigarettes without having to purchase a pack. Selling of loosies may cue smoking behaviors. In the US, socioeconomically disadvantaged populations have high rates of smoking and illicit drug use and the selling of loosies appears to be linked to the urban informal economy. We examined the proportion and frequency of cigarette selling and roles in the informal economy associated with selling loosies among a sample of urban drug users.

METHODS

There were 801 participants, recruited by community outreach, assessed at baseline, who were enrolled in an HIV prevention intervention for drug users.

RESULTS

Most (89%) smoked cigarettes in the prior 30 days, of whom 92% smoked daily. Self-reported selling of cigarettes was common with 58% reporting that they had sold cigarettes within the last six months; 20.4% reported selling cigarettes a few times a week and 7.4% reported daily selling of cigarettes. In a stepwise regression model, four sources of income were associated with frequent cigarette selling: providing street security (OR=2.214, 95% CI 1.177-4.164), selling food stamps (OR=1.461, 95% CI 1.003-2.126), pawning items (OR=2.15, 95% CI 1.475-3.135), and selling drugs (OR=1.634, 95% CI 1.008-2.648).

CONCLUSION

There is a high rate of selling loosies among urban substance users. The wide availability of loosies may promote smoking. Smoking cessation programs with drug treatment and economic development programs may help to reduce economic pressures to sell loosies.

Characterizing smoking, cessation services, and quit interest across outpatient substance abuse treatment modalities

The majority of individuals seeking treatment for substance use disorders are cigarette smokers, yet smoking cessation is rarely addressed during treatment. Conducting a detailed smoking-related characterization of substance abuse treatment patients across treatment modalities may facilitate the development of tailored treatment strategies. This study administered a battery of self-report instruments to compare tobacco use, quit attempts, smoking knowledge and attitudes, program services, and interest in quitting among smoking patients enrolled in opioid replacement therapy (ORT) versus non-opioid replacement (non-ORT). ORT compared with non-ORT participants smoked more heavily, had greater tobacco dependence, and endorsed greater exposure to smoking cessation services at their treatment programs. Favorable attitudes towards cessation during treatment were found within both groups. These data identify several potential clinical targets, most notably including confidence in abstaining and attitudes toward cessation pharmacotherapies that may be addressed by substance abuse treatment clinics.

Smoking and opioid detoxification: behavioral changes and response to treatment

INTRODUCTION

The relevance of tobacco use in opioid addiction (OA) has generated a demand for available and more effective interventions. Thus, further analysis of less explored nicotine-opioid clinical interactions is warranted.

METHODS

A post-hoc analysis of OA participants in a double-blind, randomized very low dose naltrexone (VLNTX) inpatient detoxification trial evaluated measures of opioid withdrawal and tobacco use. Intreatment smokers were compared with nonsmokers, or smokers who were not allowed to smoke.

RESULTS

A total of 141 (81%) of 174 OA participants were smokers, all nicotine-dependent. Inpatient smoking was a predictor of opioid withdrawal discomfort. Intreatment smokers (n = 96) showed significantly higher opioid craving (F = 3.7, p < .001) and lower detoxification completion rate (χ(2) = 7.9, p < .02) compared with smokers who were not allowed to smoke (n = 45) or nonsmokers (n = 33). Smoking during treatment was associated with more elevated cigarette craving during detoxification (F = 4.1, p < .001) and a higher number of cigarettes smoked at follow-up (F = 3.6, p < .02). Among intreatment smokers, VLNTX addition to methadone taper was effective in easing opioid withdrawal and craving more than other treatments, whereas the combination VLNTX-clonidine was associated with significantly reduced cigarette craving and smoking during detoxification.

CONCLUSIONS

Failure to address tobacco use may negatively affect pharmacologically managed opioid discontinuation. Opioid detoxification may offer a window of opportunity to expand smoking cessation treatment, hence improving OA outcomes. The observed effects support testing of VLNTX-clonidine in smoking cessation trials among individuals with or without substance abuse.

Interventions for tobacco use cessation in people in treatment for or recovery from substance abuse

This is the protocol for a review and there is no abstract. The objectives are as follows: To evaluate the effectiveness of tobacco cessation therapy offered concurrently with treatment for drug and alcohol addiction.

Nicotine dependence among clients receiving publicly funded substance abuse treatment

BACKGROUND

Smoking and nicotine dependence (ND) are prevalent among substance abusers but little is known about characteristics of ND in this population. This information would help identify those most in need of smoking cessation programs. This study evaluated the associations of socio-demographic, tobacco- and substance use-related, and health/mental health factors to ND in adults receiving publicly funded substance abuse treatment in Tennessee.

METHODS

All Tennessee residents who received federal block grant-funded substance abuse treatment during July-December, 2004 were invited to participate in a 6 month post-intake telephone follow-up interview. Socio-demographic characteristics, perceived health and mental health, tobacco use history and patterns, and ND, assessed by the Fagerstrom Test of Nicotine Dependence (FTND), were obtained at follow-up. Alcohol and illicit drug use and smoking status prior to treatment were assessed at intake. This paper analyzes data for 855 clients who were current cigarette smokers at both intake and follow-up.

RESULTS

Sixty three percent of smokers were ND (FTND score ≥ 4). Correlates of ND included older age, poorer self-rated overall health, earlier age of onset of cigarette smoking and substance abuse, fewer smoking quit attempts in past year, single substance use (alcohol or illicit drug, vs. multiple substances) at intake, use of opiates/narcotics and sedatives, and past month self-reported depression.

CONCLUSION

ND was highly prevalent and correlated with specific types and patterns of substance abuse and depression. These results suggest that intensive smoking cessation interventions, involving behavioral support, pharmacotherapy, and mood management, are needed to effectively assist this population.

The New York policy on smoking in addiction treatment: findings after 1 year

OBJECTIVES

We assessed changes in smoking prevalence and other measures associated with the July 2008 New York Office of Alcoholism and Substance Abuse Services tobacco policy, which required that all publicly funded addiction treatment programs implement smoke-free grounds, have "no evidence" of smoking among staff, and make tobacco dependence treatment available for all clients.

METHODS

In a random sample of 10 programs, staff and clients were surveyed before the policy and 1 year later. Measures included tobacco-related knowledge, attitudes, and practices used by counselors and received by clients.

RESULTS

Client smoking decreased from 69.4% to 62.8% (P = .044). However, response to the policy differed by program type. Outpatient programs showed no significant changes on any of the staff and client survey measures. In methadone programs, staff use of tobacco-related practices increased (P < .01), client attitudes toward tobacco treatment grew more positive (P < .05), and clients received more tobacco-related services (P < .05). Residential clients were more likely to report having quit smoking after policy implementation (odds ratio = 4.7; 95% confidence interval = 1.53, 14.19), but they reported less favorable attitudes toward tobacco treatment (P < .001) and received fewer tobacco-related services from their program (P < .001) or their counselor (P < .001).

CONCLUSIONS

If supported by additional research, the New York policy may offer a model that addiction treatment systems can use to address smoking in a population where it has been prevalent and intractable. Additional intervention or policy supports may be needed in residential programs, which face greater challenges to implementing tobacco-free grounds.

Addressing Tobacco Through Organizational Change (ATTOC) in residential addiction treatment settings

BACKGROUND

Smoking prevalence among persons in addiction treatment is 3-4 times higher than in the general population. However, treatment programs often report organizational barriers to providing tobacco-related services. This study assessed the effectiveness of a six month organizational change intervention, Addressing Tobacco Through Organizational Change (ATTOC), to improve how programs address tobacco dependence.

METHODS

The ATTOC intervention, implemented in three residential treatment programs, included consultation, staff training, policy development, leadership support and access to nicotine replacement therapy (NRT) medication. Program staff and clients were surveyed at pre- and post-intervention, and at 6 month follow-up. The staff survey measured knowledge of the hazards of smoking, attitudes about and barriers to treating smoking, counselor self-efficacy in providing such services, and practices used to address tobacco. The client survey measured knowledge, attitudes, and tobacco-related services received. NRT use was tracked.

RESULTS

From pre- to post-intervention, staff beliefs became more favorable toward treating tobacco dependence (F(1, 163)=7.15, p=0.008), NRT use increased, and tobacco-related practices increased in a non-significant trend (F(1, 123)=3.66, p=0.058). Client attitudes toward treating tobacco dependence became more favorable (F(1, 235)=10.58, p=0.0013) and clients received more tobacco-related services from their program (F(1, 235)=92.86, p<0.0001) and from their counselors (F(1, 235)=61.59, p<0.0001). Most changes remained at follow-up.

CONCLUSIONS

The ATTOC intervention can help shift the treatment system culture and increase tobacco services in addiction treatment programs.

Alcohol and marijuana use in the context of tobacco dependence treatment: impact on outcome and mediation of effect

INTRODUCTION

Alcohol and marijuana are among the most commonly used substances together with tobacco worldwide, but their relationship to smoking cessation is unclear. Although alcohol use decreases the likelihood of abstinence from tobacco, mechanisms of this effect have not been identified. Moreover, a small literature has yielded inconsistent findings regarding the effect of marijuana use on tobacco dependence treatment outcome. The aims of this study were to test increased positive-reinforcement smoking urge as a mediator of the relationship between alcohol and cigarette use and evaluate the impact of marijuana use on abstinence from tobacco.

METHODS

Participants were adult cigarette smokers (N = 739) from 3 randomized clinical trials of smoking cessation treatment. Alcohol consumption and marijuana use were assessed at pretreatment and postcessation. Biochemically verified, 7-day point prevalence smoking abstinence was determined at Weeks 12, 24, 36, and 52, as were urges to smoke as measured by the Questionnaire of Smoking Urges.

RESULTS

Increased positive-reinforcement urge mediated the effect of postcessation alcohol use on smoking abstinence. Although pretreatment alcohol use was associated with a decreased likelihood of abstinence from tobacco, increased positive-reinforcement urge did not account for this relationship. Marijuana use was not associated with abstinence from tobacco.

CONCLUSIONS

Smoking cessation treatments should provide those who drink during a quit attempt techniques designed to mitigate positive-reinforcement urge to smoke. Additional research is needed to determine how pretreatment alcohol consumption exerts its effect on cigarette use. Modifying the use of marijuana might not be critical to the success of tobacco interventions.
