Youth e-cigarette bans increase youth cigarette smoking
Friedman used smoking data from the National Survey on Drug Use and Health from 2002 to 2013. She accounted for other youth-smoking factors that vary among states, such as cigarette taxes, smoke-free air laws and medical marijuana laws. Friedman concludes:
Across the board, this paper’s analyses find that reducing e-cigarette access increases smoking among 12 to 17 year olds. The effect is large: over the eight years preceding the first bans on e-cigarette sales to minors, smoking in this age group fell an average of 1.3 percentage points per two year period. The estimated 0.9 percentage point rise in smoking due to bans on e-cigarette sales to minors counters 70 percent of the downward pre-trend in states with such bans.
This paper’s findings will prove surprising for many: policy discussions to date have not considered that banning e-cigarette sales to minors might increase teen smoking. Assuming that e-cigarettes are indeed less risky to one’s health than traditional cigarettes, as suggested by existing evidence on the subject, this result calls such bans into question.

Friedman makes a bold suggestion – one that is sensible and defensible: ban e-cig “sales to those younger than 16 instead of 18, as initiation of regular smoking first spikes at the former age.”
E-cigarette companies and advocates support bans on e-cig sales to minors. While health organizations like the American Cancer Society and Heart Association object to youth e-cig use, they oppose bans for two reasons:
- E-cig companies support them; and
- According to the health groups, youth bans are not as effective as higher sales taxes and smoke-free or clean-air laws (discussed here).
E-cigarette opponents have been quick to challenge the Yale study. In a Winston-Salem Journal article, Dr. John Spangler of Wake Forest Baptist Medical Center called the study flawed because it “does not account for unmeasured factors, such as racial and ethnic population mix in states.” This is a false charge, as the researchers adjusted “for the percent of [each] state’s population identifying as Black, as a different racial minority, and as Hispanic.” These factors were noted in all three results tables.
Other e-cig prohibitionists support the bizarre logic of University of California-San Francisco professor Stanton Glantz, who has argued in the past that banning e-cigarette sales to kids only makes teens want them more. Friedman’s study turns this argument on its head: banning e-cig sales increases teen smoking.
