简要总结
The purpose of the study is to evaluate how limiting the nicotine content in regular cigarettes affects choices for regular cigarette and e-cigarette products. Eligible participants will be of legal age to purchase tobacco products and regularly use both e-cigarettes and regular cigarettes.
详细描述
Participants in this study will undergo an in-person screening session where the study will be explained in detail and participants will answer questions and provide a breath sample. During the screening session, participants will also be asked to complete surveys. Eligible participants will then complete the training procedures during which they will select an e-cigarette device to use for future preference sessions. During the 4 preference sessions, participants will sample puffs from an e-cigarette and regular cigarette and answer questions about their experience with each. They will also complete a task during which they can choose to earn puffs from the e-cigarette or regular cigarette, or choose to not take any puffs. The 4 sessions will be the same except that a different combination of e-cigarette and regular cigarette is used at each session.
