A study of Grade 9 to 12 students in Ontario and Alberta points to a "strong and robust" linkage between so-called vaping and subsequent tobacco use. The study, which suggests teenagers who use electronic cigarettes are at risk of graduating to tobacco smoking, classified students into six categories: current daily smokers, current occasional smokers, former smokers, experimental smokers, puffers; and those who had never tried smoking. The study finds teens who vaped in the 30 days prior to the start of the study were more likely to start smoking cigarettes and to continue smoking after one year. Among the findings:
- Past 30-day e-cigarette use increased from 2013/14 to 2014/15 (7.2% v. 9.7%);
- Past 30-day cigarette smoking decreased slightly (11.4% v. 10.8%).; and
- Past 30-day use of e-cigarettes at baseline was associated with initiation of smoking a whole cigarette (adjusted odds ratio 2.12) and with initiation of daily smoking (adjusted OR 1.79) at follow-up.
A federal bill under consideration, Bill S-5, would:
- Create new regulations governing e-cigarettes,
- Outlaw the sale of vaping products to minors;
- Prohibit the promotion of e-cigarettes containing flavours that appeal to youth; and
- Restrict advertising of these products.
