According to the FDA, the price is worth paying to prevent teenagers from using e-cigarettes. But that goal is itself questionable on public health grounds.

FDA Commissioner Scott Gottlieb, who announced the flavor restrictions four months before he revealed that he'd be leaving the agency in April, said he worried that vaping might be a gateway to smoking. Yet there is little evidence of that.

A study published by the Journal of the National Cancer Institute in January, based on a sample of 12,000 12- to 17-year-olds who were surveyed on two occasions one year apart, confirmed that teenagers who try e-cigarettes are more likely than those who don't to subsequently try conventional cigarettes.
