Electronic Cigarette Trial and Use among Young Adults: Reasons for Trial and Cessation of Vaping

This paper identifies predictors of trial and current use, and reasons for trying and ceasing use of electronic cigarettes (e-cigarettes) among young adults, with particular attention to former and never smokers. Data are from a mail survey of a population-based sample of adults aged 18 to 35 (N = 4740) in three U.S. metropolitan areas. Survey items assessed trial and use of e-cigarettes, cigarette smoking status, and reasons for trial and for ceasing use of e-cigarettes. Almost 23% reported trial of e-cigarettes, and 8.4% reported using them in the past month. Current smokers were much more likely to have tried e-cigarettes (70.2%) than both former (32.3%) and never smokers (7.6%; p < 0.001) and to have used them in the past month (30.8%, 10.1%, 2.0% respectively; p < 0.001). Smoking status and scores on sensation seeking were significant independent predictors of both trial and current use of e-cigarettes. Never-smokers cite curiosity as the reason for trying e-cigarettes and also that their friends used them. The most frequent reason for ceasing use among never and former smokers was health concerns. For virtually none of them were e-cigarettes their first exposure to nicotine.
