Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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 understand how different types of e-cigarettes are likely to influence cigarette and e-cigarette use.
