Minor Vapists

The Yale School of Medicine reports on some of the benefits of vaping and some of the costs of bans:

More than 40 states have banned the sale of electronic cigarettes to minors, but a new study out of the Yale School of Public Health indicates that these measures have an unintended and dangerous consequence: increasing adolescents’ use of conventional cigarettes.

Using data from the National Survey on Drug Use and Health, the research finds that state bans on e-cigarette sales to minors yield a 0.9 percentage point increase in rates of recent conventional cigarette use by 12 to 17 year olds, relative to states without these bans.

“Conventional cigarette use has been falling somewhat steadily among this age group since the start of the 21st century. This paper shows that bans on e-cigarette sales to minors appear to have slowed this decline by about 70 percent in the states that implemented them,” said Abigail Friedman, assistant professor of public health and the study’s author. “In other words, as a result of these bans, more teenagers are using conventional cigarettes than otherwise would have done so.”

The paper by Abigail Friedman is forthcoming in the Journal of Health Economics (working paper version).
