The “gateway” effect of e-cigarettes may be explained by a genetic liability to risk-taking

Abstract

E-cigarettes have become a popular method of smoking cessation and a long-term reducedharm alternative to tobacco smoking in countries that allow their sale There is reasonable evidence of their effectiveness for smoking cessation In Australia, concern about this putative gateway effect has led health regulators to ban the sale of e-cigarettes to adult smokers without a medical prescription [5]. In surveys, most adolescents and young adults who have used e-cigarettes have smoked cigarettes (although fewer have done so before than after smoking) Some authors have seen these findings as evidence that e-cigarettes are a gateway to smoking
