Nicotine in e-cigarettes

When ever-users of e-cigarettes were asked whether the last one they used contained nicotine, nearly two-thirds (64.4%a) said it did, despite nicotine-containing e-cigarettes not being approved for sale in Canada at the time of the survey.xx This represented a significant increase from 47.8%b of users in 2015.174 In 2017, 23.8%c said the last e-cigarette they used did not contain nicotine. Approximately one in eight users (11.8%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 significantly by smoking status175 (Figure 12.19); three-quarters (75.0%e) of current smokers used e-cigarettes containing nicotine, as well as the majority (64.1%f) of former smokers, compared to less than half (42.7%g) of never smokers.

 As shown in Figure 12.20, while it appears that slightly more male smokers and non-smokers (vs. females) used e-cigarettes containing nicotine, neither difference was statistically significant.176,177
