Surgeon General calls youth vaping a public health threat

There's no scientific consensus on the risks or advantages of vaping, including how it affects the likelihood of someone either picking up regular tobacco products or kicking the habit.

Earlier this year, the Food and Drug Administration issued new rules that, for the first time, will require makers of nicotine-emitting devices to begin submitting their ingredients for regulators to review.

The vaping industry argues the regulations will wipe out small companies in favor of more harmful products, and likely will lobby the incoming Trump administration to undo the rules.
