Varenicline and Motivational Advice for Smokers With SUD
The purpose of this study is to evaluate the effects of 12 weeks of varenicline as compared to nicotine replacement therapy for smoking cessation among outpatients in treatment for substance use disorders.
The intervention also incorporates counseling (Brief Advice), (adapted for sobriety settings), skills training and medication management.

Description détaillée
People with substance use disorders (SUD) have a high prevalence and rate of smoking with little success in quitting, so stronger approaches are needed to encourage attempts to quit smoking. Brief advice (BA), to motivate cessation, produced some benefit but low abstinence rates for smokers with SUDs while adding free transdermal nicotine replacement therapy (NRT) improved short-term cessation rates. Varenicline has been found to produce higher rates of short and long-term abstinence than bupropion or placebo. However, a comparison between the efficacy of varenicline and NRT has not yet conducted with people with SUDs. Given the lack of effectiveness for standard smoking treatments for this population, what needs to be known is whether varenicline would increase the smoking abstinence rates relative to NRT when all receive motivational counseling.
The primary aim of this study is to evaluate the effects of 12 weeks of varenicline as compared to NRT, using a two-group randomized placebo-controlled design on smoking cessation rates for 12 months among 274 outpatients in treatment for SUD. The counseling incorporates BA (adapted slightly for sobriety settings by directly addressing barriers and concerns expressed by substance abusers), skills training and medication management. Confirmed point-prevalence and sustained abstinence will be assessed at 3 and 6 a months after the start of treatment. Secondary aims will examine potential mediators of effect including within-treatment abstinence, craving, and nicotine withdrawal levels.
The potential significance is to add to knowledge about the most effective ways to maximize smoking cessation among substance abusers, important given that no methods are known to work with this difficult population. No study published to date has compared varenicline to NRT for efficacy with patients with SUD.

Nicotine replacement treatment (NRT) will follow the clinical practice guidelines for nicotine patch for people smoking at least 10 cigarettes per day (USDHHS, 2000), modified to allow 12 weeks use (tapering recommended for people with AUDs by Hughes et al., 2003b): 21 mg/day for 4 weeks, 14 mg/day for 4 weeks, 7 mg/day for 4 weeks.
Autres noms:
The counseling consists of 10 sessions of Brief Advice (BA).BA is a simple smoking cessation counseling strategy: Assess smoking and initial interest in cessation, advise patient to quit smoking, assist patient in quitting, discussion of sobriety specific concerns, and cognitive-behavioral skills training.
Medication management is conducted in every session, smoking cessation pamphlets are available.
Session 1 (60 min, in-person) will be 1 week before Quit Day.Session 2 (30 min, in-person) takes place on Quit Day.
Session 3 (10 min, in-person) will be 1 week later.
Sessions 4-10 will be 5-10 min.
telephone contacts at Weeks 2, 3, 4, 6, 8, 10, and 12 after Quit Day.
