The goal of this research is to understand how different types of e-cigarettes affect tobacco use. Participants will either be assigned to a control group that does not receive an e-cigarette or be assigned to receive one of two different types of e-cigarettes to sample in the lab and at home. We will measure participants' smoking and smoke exposure during the study.
The purpose of this project is to understand how different e-cigarettes influence their likeability and use among current smokers who try using e-cigarettes. Participants will receive an e-cigarette to sample over a three week period. During this time period they will complete daily electronic diaries and weekly lab visits. The results from this information will help us understand how different types of e-cigarettes are likely to influence cigarette and e-cigarette use.
