Federal rules expected to be released soon — more than three months after President Donald Trump promised a crackdown on vaping amid a pair of related public health crises — include new carveouts that will allow some products to remain on the market. The Wall Street Journal first reported the news.

The Food and Drug Administration will ban major retailers, gas stations and convenience stores from selling all fruit- and sweet-flavored vapes, which have been blamed for the sharp rise in teen use. However, in a major reversal, the agency will allow menthol-flavored e-cigarettes to be widely available, and open tank vapes commonly sold in vape shops will also be excluded from the ban, an HHS official confirms.

The decision is a win for some of Trump’s conservative allies, who warned a more sweeping ban on flavored vaping products would alienate the president’s base and weaken his reelection effort. However, the carveouts have angered public health groups.
