Purpose:

The goal of this study is to evaluate the effects of exposure to standard smoking environments on ability to resist smoking as measured with a Delay to Smoking Task. The results of this study will inform whether the Delay to Smoking Task is a sensitive measure for evaluating environment-provoked craving and smoking behavior.


Study summary:

Adult smokers (n=25) will complete 4 visits and a 6 month follow-up phone call. Participants will complete a Delay to Smoking Task following 6 hours smoking abstinence. The task involves viewing pictures of smoking and non-smoking locations and participants will have the choice to smoke a cigarette at any time during the session. A monetary reinforcer will be provided for each 6-minute period that a participant resists smoking. Once participants stop the task they can choose to smoke as much or a little as they want for the next 30 minutes. Participants will be provided with a smoking tab. Each cigarette they light will cost them from their tab. Measurements of tobacco craving, emotion ratings, and nicotine withdrawal will be assessed.
