Electronic cigarettes in Canada: prevalence of use and perceptions among youth and young adults.

OBJECTIVES The goal of this study was to examine the prevalence and perceptions of electronic cigarette use among Canadian youth and young adults. METHODS A sample of 1,188 youth and young adults age 16-30 years were recruited from an online panel of Canadians in 2012. After viewing an image of an e-cigarette, respondents answered questions regarding their use and perceptions of e-cigarettes. RESULTS Close to half of respondents (43.4%) had seen e-cigarettes advertised or for sale. A total of 16.1% reported trying an e-cigarette (5.2% nonsmokers, 18.9% former smokers, and 34.5% current smokers), and 5.7% reported use in the past 30 days (0.8% non-smokers, 1.4% former smokers, and 15.0% current smokers). Compared to non-smokers, former smokers and current smokers were more likely to have tried e-cigarettes (OR=4.25 and OR=9.84, respectively), and current smokers were more likely to have tried e-cigarettes than former smokers (OR=2.32). Current smokers were also more likely to be current users of e-cigarettes than both former smokers (OR=15.15) and non-smokers (OR=4.43). Smokers were interested in trying e-cigarettes to help them quit smoking (80.4%), as a long-term replacement for cigarettes (77.8%), or to use in places where they cannot smoke (80.9%). CONCLUSIONS Awareness of e-cigarettes among surveyed youth and young adults is quite high. Almost one fifth (16.1%) of participants reported trying e-cigarettes, with evidence of use among non-smokers.
