*Using a simple model of competition between traditional cigarettes and e-cigarettes for users, we predict the change in smoking prevalence due to the introduction of vaping in the U.S. Vaping products appear to decrease the prevalence of smoking among both adult and adolescent populations. Because the long-term health risks of vaping are currently unknown, the public health cost and/or benefit of e-cigarette is less clear. However, as suggested by our model, it is possible that the introduction of e-cigarettes will have positive effects for both adult and youth populations depending on the relative health risk of smoking and vaping. | *Using a simple model of competition between traditional cigarettes and e-cigarettes for users, we predict the change in smoking prevalence due to the introduction of vaping in the U.S. Vaping products appear to decrease the prevalence of smoking among both adult and adolescent populations.

===2021: [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8145156/ A Difference-in-Differences Analysis of Youth Smoking and a Ban on Sales of Flavored Tobacco Products in San Francisco, California]=== | |||
*San Francisco’s ban on flavored tobacco product sales was associated with increased smoking among minor high school students relative to other school districts. While the policy applied to all tobacco products, its outcome was likely greater for youths who vaped than those who smoked due to higher rates of flavored tobacco use among those who vaped. This raises concerns that reducing access to flavored electronic nicotine delivery systems may motivate youths who would otherwise vape to substitute smoking. Indeed, analyses of how minimum legal sales ages for electronic nicotine delivery systems are associated with youth smoking also suggest such substitution. | |||

*Young adult e-cigarette users indicate low support for e-cigarette sales restrictions (both for flavored products and complete restrictions). Moreover, if vape product sales were restricted to tobacco flavors, 39.1% of users reported being likely to continue using e-cigarettes but 33.2% were likely to switch to cigarettes. If vape product sales were entirely restricted, e-cigarette users were equally likely to switch to cigarettes versus not (~40%). | |||

*In the event of a ban on other flavours, 20% of the NZ residents said they would probably go back to smoking (see Table 3). A majority (57%) indicated they intended to circumvent the ban, by mixing their own liquids and/or buying from overseas or the black market. Only 29% indicated they would change their vaping consumption to comply with the ban, as is typically implicitly assumed will happen. Nine percent would try to stop vaping and 35% would buy only the legal products (which includes the 18% who were already buying only products that would not be banned). | |||

*Among the 18–24 age group, there was a significant increase in cigarette smoking. | |||
*Cigarette smoking increased among 25–34 years old. | |||
*'''Banning flavors in e-cigarettes can push some e-cigarette users to turn to cigarette smoking''' and could prompt some youth to initiate into smoking instead of e-cigarette use. | |||
*The proportions of e-cigarettes, cigarettes, and cigars obtained over the internet increased after the ban, and the proportions obtained from retailers outside of San Francisco also increased overall. | |||
