Effects of e-Cigarettes on Perceptions and Behavior - Substudy 1

Effects of e-Cigarettes on Perceptions and Behavior - Substudy 1

This project will assess the ways in which e-cigarette product diversity impacts the user experience to inform potential regulations by identifying product characteristics that may: (1) put young adults at risk for tobacco product use; and (2) facilitate adult smokers switching to e-cigarettes. There are three primary objectives to the study: (1) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect product appeal across young adult e-cigarette users and middle-age/older adult smokers; (2) Determine which dimensions of e-cigarette product diversity differentially affect product appeal in the overall population of tobacco product users as well as affect abuse liability in young adult e-cigarette users and the ability to resist smoking in adult smokers; (3) Determine the affect of product characteristics on e-cigarette nicotine delivery profile. For this substudy, young adult vapers (N=100) and adult smokers (N=100) will attend one laboratory session in which they will self-administer e-cigarette products varied according to within-subject e-cigarette factors (e.g., flavor, nicotine formulation).
