“…8–11 Nevertheless, studies that have evaluated the effectiveness of e-cigarettes for smoking cessation have produced mixed results. 5,12 Moreover, longitudinal studies in the US, Canada and the UK indicate that e-cigarette use among non-smoker adolescents substantially increases the risk of initiating cigarette use, 13–18 raising concerns that e-cigarettes may promote cigarette smoking among youth who would not have otherwise become smokers. Indeed, a recent longitudinal study of Mexican adolescents found similar results; 19 however, more research is sorely needed to better understand the patterns of use and potential public health impact of e-cigarettes in low- and middle-income countries (LMICs).…”

“…Our finding that, regardless of school type, the association between tobacco use and e-cigarette use, as well as morning craving, is consistent with existing findings that e-cigarette use was associated with morning smoking urge 20 and ever tobacco use 11,20 . No longitudinal study has explored the causal relationship between tobacco and e-cigarette use 7 . Our finding implies that e-cigarette control programs should also include elements targeting tobacco use simultaneously.…”

“…A British survey found that about a tenth to a fifth of those aged 11-16 years had tried e-cigarettes 6 . In Canada, about 20% of youth aged 15-19 years reported 'ever tried' e-cigarettes, of whom 14% were non-smokers 7 . In South Korea, about 9-10% of adolescents were found to be e-cigarette users, of whom 75-76% also used tobacco 8 .…”

“…A number of studies have examined factors associated with e-cigarette use among adolescents. E-cigarette use has been strongly linked to smoking and susceptibility to smoking 7 . A study found curiosity was the most commonly cited reason among less frequent e-cigarette users, while the desire to quit smoking and the opportunity for indoor use were the most commonly cited reasons among more frequent users 11 .…”

INTRODUCTION Studies examining e-cigarette use among adolescents in Shanghai, China, have focused largely on middle school students. Given the vast differences between vocational and traditional schools, we aimed to explore school-type differences in e-cigarette use and correlates among adolescents in Shanghai. METHODS The study was conducted in September 2017 through multistage and stratified cluster random sampling, which consisted of 10699 adolescents aged 13-17 years attending traditional and vocational schools in Shanghai. Descriptive statistics and multivariate logistic regressions were conducted to assess the weighted prevalence and correlates of ever e-cigarette use stratified by school type. RESULTS The weighted prevalence of e-cigarette use was 5.21% among all respondents. Although e-cigarette use was more prevalent among students attending vocational schools (p<0.001), its correlates were similar across both school types. Among vocational school students, ever tobacco use (OR=3.10; 95% CI: 2.36-4.08) was the most significant correlate, followed by having most friends as smokers (OR=2.97; 95% CI: 1.84-4.81) and having morning cravings (OR=1.90; 95% CI: 1.64-2.20). Among traditional school students, having most friends as smokers (OR=4.87; 95% CI: 2.78-8.54) and ever tobacco use (OR=3.78; 95% CI: 2.68-5.34) were the most significant correlates, followed by knowledge of pro-tobacco advertisements (OR=2.12; 95% CI: 1.54-2.91).

“…ENDS may act as a gateway to cigarette smoking . There is no doubt that ENDS companies, many of whom have been acquired by ‘big tobacco’, are targeting youth through direct advertising and promotion of sweet flavoured ENDS, which are preferred by children .…”

E‐cigarettes, or electronic nicotine delivery systems (ENDS), have been suggested as a potential aid for smoking cessation, but many questions about their efficacy and safety remain unanswered. Until very recently, the evidence for ENDS in smoking cessation was largely based on observational studies or randomised controlled trials with methodological flaws and did not provide adequate evidence to support strongly ENDS for smoking cessation. Concerns about the uptake of ENDS by nonsmoking populations (such as adolescents) remain. More recent evidence may indicate the effect of ENDS in smoking cessation, but many questions remain unanswered. In this article, we address recent claims that failure to recommend ENDS for smoking cessation represents unethical practice. We strongly dispute this claim, analysing the many complex issues that clinicians working in smoking cessation should consider.
