Cigarette Smoking, Tobacco Use
Conditions
Brief summary
This one-year pilot study of 30 non-treatment seeking young adult e-cigarette/combustible tobacco product dual users (15 males/15 females) will use smartphone-based ecological momentary assessment (EMA) to gather real-time data of e-cigarette and combustible tobacco product behaviors during a 1-week cigarette/e-cigarette dual use period .(1) Participants will respond to daily random prompts assessing in-the-moment use of e-cigarettes/cigarettes and the subjective factors (ratings of satisfaction and withdrawal) and contextual factors (location, activity, social cues) associated with each episode of use. Participants will also complete daily electronic diaries to document e-cigarette use episodes/day, and satisfaction with the e-cigarette experience during the study.
