ABSTRACT
OBJECTIVES: Combined smoking and heavy drinking is a significant health burden. Varenicline, an efficacious tobacco pharmacotherapy that also shows promise for drinking, has yielded mixed results among heavy-drinking smokers. This pilot study investigated integrated tobacco and alcohol counselling plus varenicline for this vulnerable group. DESIGN: Twelve-week parallel, randomized controlled pilot trial of two behavioural interventions in combination with open-label varenicline. Participants were randomized using computer-generated tables, stratified by sex. SETTING: Outpatient academic medical centre research clinic. PARTICIPANTS: Volunteers who reported smoking and heavy drinking and sought tobacco or alcohol treatment (N = 26). Intervention. (1) Integrated tobacco + alcohol counselling (INT; n = 13) or (2) counselling focused on their presenting concern (i.e., tobacco or alcohol) (SINGLE; n = 13), plus varenicline (2 mg) for 12 weeks. MAIN OUTCOMES: Feasibility/acceptability, smoking quit rates and heavy drinking. RESULTS: INT feasibility/acceptability was high among men but not women. More participants quit smoking in INT than SINGLE. This outcome was only in men, not significant, but had a medium effect size. Both conditions yielded significant drinking reductions. CONCLUSION: Integrated tobacco and alcohol behavioural counselling plus varenicline may be feasible and promote smoking cessation among men who smoke and drink heavily, but a larger sample is needed to replicate this finding.
ABSTRACT
INTRODUCTION: Sleep disturbance is common among cigarette smokers and predicts smoking cessation failure. AIMS: The purpose of this study was to conduct a pilot test of whether provision of a sleep intervention might bolster smoking cessation outcomes among this vulnerable group. METHODS: Smokers with insomnia (N = 19) seeking smoking cessation treatment were randomly assigned to receive 8 sessions over 10 weeks of either: (1) cognitive-behavioural therapy for insomnia + smoking cessation counselling (CBT-I+SC; n = 9) or (2) smoking cessation counselling alone (SC; n = 10). Counselling commenced 4 weeks prior to a scheduled quit date, and nicotine patch therapy was also provided for 6 weeks starting on the quit date. RESULTS: There was no significant effect of counselling condition on smoking cessation outcomes. Most participants had difficulty initiating and maintaining smoking abstinence in that 7-day point prevalence abstinence rates at end of treatment (CBT-I+SC: 1/7, 14%; SC: 2/10, 20%) and follow-up (CBT-I+SC: 1/7, 14%; SC: 0/10, 0%) were low for both conditions. CBT-I+SC participants reported improvements in sleep efficiency, quality, duration and insomnia symptoms. Sleep changes were not associated with the likelihood of achieving smoking abstinence. CONCLUSIONS: This randomised pilot study suggests that behavioural interventions may improve sleep among smokers with insomnia, but a larger sample is needed to replicate this finding and evaluate whether these changes facilitate smoking cessation.
