Combined Treatment for Tobacco and Alcohol Use

The specific aims are to: * Develop a "Motivational Relapse Prevention Plus Alcohol Risk Reduction" (MRP+) approach to simultaneously treating both smoking and "at-risk" alcohol use among smokers attempting to quit smoking. * Estimate the effect size for MRP+ relative to Motivational Relapse Prevention without a focus on alcohol (MRP) with respect to alcohol at-risk behaviors. The estimated effect size will be utilized to help guide sample size estimates for a potential clinical trial.
