Motivators of e-cigarette use among Australian adolescents, young adults, and adults

There is limited research examining motivators of e-cigarette use among never smokers, a group for whom vaping has no benefits and many harms. To inform programs and policies that aim to prevent initiation and encourage cessation of e-cigarette use, this study investigated reasons for intended use, initiation, and continued use of e-cigarettes among various age and user groups in Australia. An online survey was administered to 4617 respondents. Never users of e-cigarettes and never smokers who reported intending to try e-cigarettes (n = 348), current e-cigarette users and never smokers (n = 121), and current e-cigarette users and current smokers (n = 354) were of interest to this study. Among never smokers, curiosity was the most commonly reported reason for intended use and use initiation, whereas the taste of e-cigarettes and their appealing flavours were the most frequently reported motivators of current e-cigarette use. Among smokers, taste and flavourings were the most commonly reported motivators of current use, not smoking cessation. Adolescents and young adults in most user groups were more likely than adults to report using e-cigarettes out of curiosity and because they taste good, whereas adults were more likely to use for smoking cessation purposes and because they perceived e-cigarettes to be more acceptable and cheaper than tobacco cigarettes. Results suggest that (i) prohibiting flavourings and (ii) restricting advertising that highlights the pleasurable effects of e-cigarettes could constitute potential means of preventing e-cigarette initiation and encouraging cessation among never smokers, especially adolescents.
