Many smokers drink alcohol to excess, resulting in numerous health problems and lower likelihood of quitting smoking. Smoking cessation counseling that addresses heavy drinking can reduce alcohol use and improve smokers’ chances of quitting. Delivering this kind of intervention via the Internet can reach large numbers of smokers with much less cost than in-person counseling. Led by Dr. Christopher Kahler at Brown University, this project adapted a proven smoking cessation counseling approach for heavy drinkers to be delivered via the Internet (BecomeAnEX). Usability testing and feedback from smokers about the intervention was incorporated into the final design, which was tested among 120 current smokers who enrolled on BecomeAnEX in a pilot randomized trial. Data analysis is currently underway.
