Sooyong Kim, Arielle S Selya
"Our findings show that the apparent relationship between e-cigarette use and current cigarette smoking is entirely attributable to shared risk factors for tobacco use."
Jan 04, 2021
Arielle S. Selya, Floe Foxon
Using data simulations, these researchers have concluded that the "gateway" effect (that youth who vape will progress to smoking) does not align with the real-world data reported in the CDC's National Youth Tobacco Surveys. In fact, they find that the most likely scenario is that vaping diverts youth from smoking.
March 18, 2021
Wayne Hall, Gary Chan
"E-cigarette use has also not been accompanied by increased cigarette smoking among young people in the United States, as would be the case if e-cigarette use were a major gateway to cigarette smoking. The latter findings suggest that any gateway effect of e-cigarettes is small at the population level because smoking prevalence has continued to decline, despite an increased uptake of e-cigarettes among young adults in countries that allow their sale."
May 15, 2021
Natasha A Sokol, Justin M Feldman
"Vaping is largely concentrated among non-smoking youth who would likely have smoked prior to the introduction of e-cigarettes, and the introduction of e-cigarettes has coincided with an acceleration in the decline in youth smoking rates."

Regulatory Effects

Dhaval Dave, Bo Feng, Michael F. Pesko
"...our findings suggest a possible unintended effect of e-cigarette MLSA laws-rising cigarette use in the short term while youth are restricted from purchasing e-cigarettes."
Dec 13, 2019
Henry Saffer, Michael Grossman, Daniel Dench, Dhaval Dave
"Estimates suggest that the e-cigarette tax increased adult smoking and reduced smoking cessation in Minnesota..."
May 5, 2021
Amanda Katchmar, Adrian Gunawan, Michael Siegel
"These results suggest that the Massachusetts flavor ban and tax did not reduce e-cigarette consumption in the Greater Boston area, and that messaging questioning the safety of e-cigarettes led to an increase in combustible cigarette use."
