From The Verge:
"Not only is it a problem overall, but really specifically with respect for children," Trump told reporters. He continued, "We may very well have to do something very, very strong about it."
It's unclear whether the FDA has undertaken rule-making to effect such a ban, but some kind of regulatory action appears likely. A pool report described the effort by saying, "They're trying to ban all non-tobacco flavored vaping products from the market." The FDA did not immediately respond for a request for clarification.
Looks like they want a ban on anything that is not tobacco flavored....which kinda ruins the product. Should be interesting to see the pushback from the tobacco industry.
