Conclusion: …”We also see that about one third of former smokers and over 7% of never smokers report having tried e-cigarettes, and current use is 10% and 2% in these groups, respectively. Similar findings have led others to raise concerns that e-cigarette use is a threat to public health because it can lead to combustible tobacco use, presumably among those who otherwise would not have become smokers [2]. However, it is extremely rare for e-cigarette use to be the first exposure to nicotine in young adults. It was reported by fewer than 0.4% of the never smokers, and none of the current and former smokers. This may be a cohort effect, and e-cigarette use as the initial exposure to nicotine may become more common as younger cohorts, who are experimenting with vaping at higher and higher rates, mature [19]. Nevertheless, in this cohort, 99.6% of young adult never-smokers who tried e-cigarettes had previously used or experimented with another form of tobacco, suggesting that in these young adults tobacco is a gateway to e-cigarettes, rather than the reverse.”... | Conclusion: …”We also see that about one third of former smokers and over 7% of never smokers report having tried e-cigarettes, and current use is 10% and 2% in these groups, respectively.

===2020: [https://onlinelibrary.wiley.com/doi/10.1111/add.15099 Electronic cigarettes, nicotine use trends and use initiation ages among US adolescents from 1999 to 2018]=== | |||
*Electronic cigarettes may have offset conventional smoking among US adolescents between 2010 and 2018 by maintaining the total nicotine use prevalence and diverting them from more harmful conventional smoking. Additionally, electronic cigarette users appear to initiate at older ages relative to conventional smokers, which is associated with lower risk. | |||
