Smokers' dual use of cigarettes and alternative tobacco products such as electronic cigarettes (e-cigarettes) may impact motivational and behavioral factors that affect smoking cessation success.  The goal of this project is to clarify the relationship between dual use and various health related outcomes. Researchers will recruit 150 daily smokers (75 who smoke cigarettes exclusively and 75 dual users of cigarettes and e-cigarettes) who will generate real-time data during periods of ad libitum tobacco use and periods of reduced smoking and abstinence.  Specific aims are to compare dual users and exclusive smokers on the following measures: ratings of liking cigarettes, cigarette use, daily patterns of tobacco product use, mood, suppression of cigarette withdrawal, contexts of use, and exposure biomarkers.  Dual users will also be examined with regard to e-cigarette use and ratings of liking.  This information may be used to inform regulatory actions regarding alternative tobacco products.
