Differences in young adults' perceptions of e-cigarettes by history of use

Objective: The current study examined group differences in college students' views on e-cigarettes in terms of safety, popularity, health risks, social acceptability, efficacy as a cessation aid, and promoting combustible cigarette use. Participants: 337 undergraduates (M_age = 20.84, SD = 3.79; 72.1% female; 68.5% White) divided into three groups: Never Users (n = 178), Ever Users (n = 108), and Current Users (n = 51). Methods: Participants completed questionnaires for course credit. Results: Compared to Ever and Never Users, Current Users believed e-cigarettes were safer, healthier, a useful tool to quit smoking, did not lead to combustible cigarette smoking, and that nicotine was less dangerous. Current Users also were less likely to endorse boosting social image as a motive for use. Conclusions: Public health campaigns could benefit from targeting current users' positive beliefs about e-cigarettes to reduce the prevalence of e-cigarette use among college students.
