Nicotine in e-cigarettes

When ever-users of e-cigarettes were asked whether the last one they used contained nicotine, nearly half (47.8%a) said it did, despite nicotine-containing e-cigarettes not being approved for sale in Canada.xviii This represented a significant increase from 2013,157 when 26.4%b of users reported that their last e-cigarette contained nicotine. One-third (34.5%c) said the last e-cigarette they used did not contain nicotine. Nearly one in five users (17.7%d) did not know whether their last e-cigarette contained nicotine, highlighting the importance of clear product labelling. Use of nicotine-containing e-cigarettes varied by significantly by smoking status158 (Figure 12.20); more than half of current smokers used e-cigarettes containing nicotine, as well as half of former smokers, compared to one-quarter of never smokers.

 Responses to "The last time you used an e-cigarette, did it contain nicotine?" among ever users of e-cigarettes, by smoking status, 2015. Daily smoker: responded "every day" to "at the present time do you smoke cigarettes every day, occasionally or not at all?"; Non-daily smoker: responded "occasionally" to "at the present time do you smoke cigarettes every day, occasionally or not at all?"; Former smoker: smoked "not at all" at the time of the survey, but had smoked 100+ cigarettes in lifetime. Data source: Canadian Tobacco, Alcohol and Drugs Survey, 2015. See data table with 95% confidence intervals below.

As shown in Figure 12.21, it appears that more male smokers used e-cigarettes containing nicotine, while slightly more female non-smokers used e-cigarettes with nicotine; however, neither difference was statistically significant.159,160
