In this study, the researchers combined evidence from 17 studies that had investigated e-cigarette use and subsequent smoking, where an odds ratio could be calculated, to explore whether e-cigarette use, compared to non-use, in young non-smokers is associated with subsequent cigarette use.

Jasmine Khouja [...] said: "Policymakers have used the findings of studies, including the studies we reviewed in this research, to support the heavy regulation of e-cigarettes, including restrictions on flavours and even total bans, but the evidence that e-cigarette use might cause young people to take up smoking is not as strong as it might appear."
