“…However, it should be noted that prior work has demonstrated that a substantial number of Canadian youth have tried using e-cigarettes and that never-smokers comprise the largest population of youth. 24 25 Furthermore, our findings clearly demonstrate that never-smokers who reported using e-cigarettes in the past 30 days were at an increased risk of transitioning to cigarette smoking after 2 years. As such, continued surveillance and monitoring of e-cigarette use and its relationship with cigarette smoking among youth populations should be considered a public health priority.…”

ObjectivesGiven that many adolescent e-cigarette users are never-smokers, the possibility that e-cigarettes may act as a gateway to future cigarette smoking has been discussed in various studies. Longitudinal data are needed to explore the pathway between e-cigarette and cigarette use, particularly among different risk groups including susceptible and non-susceptible never-smokers. The objective of this study was to examine whether baseline use of e-cigarettes among a sample of never-smoking youth predicted cigarette smoking initiation over a 2-year period.DesignLongitudinal cohort study.Setting89 high schools across Ontario and Alberta, Canada.ParticipantsA sample of grade 9–11 never-smoking students at baseline (n=9501) who participated in the COMPASS study over 2 years.Primary and secondary outcome measuresParticipants completed in-class questionnaires that assessed smoking susceptibility and smoking initiation.ResultsAmong the baseline sample of non-susceptible never-smokers, 45.2% of current e-cigarette users reported trying a cigarette after 2 years compared with 13.5% of non-current e-cigarette users. Among the baseline sample of susceptible never-smokers, 62.4% of current e-cigarette users reported trying a cigarette after 2 years compared with 36.1% of non-current e-cigarette users. Overall, current e-cigarette users were more likely to try a cigarette 2 years later. This association was stronger among the sample of non-susceptible never-smokers (AOR=5.28, 95% CI 2.81 to 9.94; p<0.0001) compared with susceptible never-smokers (AOR=2.78, 95% CI 1.84 to 4.20; p<0.0001).ConclusionsFindings from this large, longitudinal study support public health concerns that e-cigarette use may contribute to the development of a new population of cigarette smokers. They also support the notion that e-cigarettes are expanding the tobacco market by attracting low-risk youth who would otherwise be unlikely to initiate using cigarettes. Careful consideration will be needed in developing an appropriate regulatory framework that prevents e-cigarette use among youth.

“…More commonly assessed in youth surveys is use of e-cigarettes in the past 30 days. Across countries rates of 30-day e-cigarette use are considerably lower than for ever-use [ 21 , 22 , 23 ]. Youth who report past-30 day use are consistently more likely to also report use of tobacco products.…”

Concern has been expressed about the use of e-cigarettes among young people. Our study reported e-cigarette and tobacco cigarette ever and regular use among 11–16 year olds across the UK. Data came from five large scale surveys with different designs and sampling strategies conducted between 2015 and 2017: The Youth Tobacco Policy Survey; the Schools Health Research Network Wales survey; two Action on Smoking and Health (ASH) Smokefree Great Britain-Youth Surveys; and the Scottish Schools Adolescent Lifestyle and Substance Use Survey. Cumulatively these surveys collected data from over 60,000 young people. For 2015/16 data for 11–16 year olds: ever smoking ranged from 11% to 20%; regular (at least weekly) smoking between 1% and 4%; ever use of e-cigarettes 7% to 18%; regular (at least weekly) use 1% to 3%; among never smokers, ever e-cigarette use ranged from 4% to 10% with regular use between 0.1% and 0.5%; among regular smokers, ever e-cigarette use ranged from 67% to 92% and regular use 7% to 38%. ASH surveys showed a rise in the prevalence of ever use of e-cigarettes from 7% (2016) to 11% (2017) but prevalence of regular use did not change remaining at 1%. In summary, surveys across the UK show a consistent pattern: most e-cigarette experimentation does not turn into regular use, and levels of regular use in young people who have never smoked remain very low.

“…14 In Canada, approximately 17% of youth nationally reported having ever tried an e-cigarette. 15,16 In Ontario and Alberta, about 7.2% of grade 9 to 12 students were considered current e-cigarette users in 2013/2014 17 and 9.75% in 2014/2015. 18 However, although e-cigarettes might aid in smoking cessation among adults, 19 e-cigarette use among youth has been associated with a higher susceptibility to cigarette smoking 20 and it is not clear that they are not a gateway to use of cigarettes 21 or a means of renormalizing tobacco smoking.…”
