The current study examined the relation between drinking and smoking abstinence in a community-based sample from the Working Well Trial (WWT). At baseline, drinking level was related to smoking history (never, former, or current smoker; P < .0001) and abstinence history. Mean monthly alcohol consumption increased linearly with decreases in duration of recent abstinence (i.e., longest period quit in the past year among current smokers; P < .05) and current abstinence (i.e., time since quitting among former smokers; P < .0001), even controlling for relevant demographic factors. Among baseline smokers, lower beer consumption predicted smoking abstinence at 4-year follow-up (P< .01). A trend towards significance was found for total alcohol consumption (P = .06). The results suggest (a) a dose-response relation between baseline drinking and duration of smoking abstinence, and (b) that heavier drinkers are less likely to quit smoking over a 4-year period.

Tobacco and alcohol use are linked behaviors that individually and synergistically increase the risk for negative health consequences. This study was a two-group, randomized clinical trial evaluating the efficacy of a behavioral intervention, "Motivation And Problem Solving Plus" (MAPS+), designed to concurrently address smoking cessation and the reduction of at-risk drinking. Targeted interventions may promote coaction, the likelihood that changing one behavior (smoking) increases the probability of changing another behavior (alcohol use). Puerto Ricans (N=202) who were smokers and at-risk drinkers were randomized to standard MAPS treatment focused exclusively on smoking cessation (S-MAPS), or MAPS+, focused on cessation and at-risk drinking reduction. Drinking outcomes included: number of at-risk drinking behaviors, heavy drinking, binge drinking, and drinking and driving. MAPS+ did not have a significant main effect on reducing at-risk drinking relative to S-MAPS. Among individuals who quit smoking, MAPS+ reduced the number of drinking behaviors, the likelihood of meeting criteria for heavy drinking relative to S-MAPS, and appeared promising for reducing binge drinking. MAPS+ did not improve drinking outcomes among individuals who were unsuccessful at quitting smoking. MAPS+ showed promise in reducing at-risk drinking among Puerto Rican smokers who successfully quit smoking, consistent with treatment enhanced coaction. Integrating an alcohol intervention into cessation treatment did not reduce engagement in treatment, or hinder cessation outcomes, and positively impacted at-risk drinking among individuals who quit smoking. Findings of coaction between smoking and drinking speak to the promise of multiple health behavior change interventions for substance use treatment and chronic disease prevention.
