The Trump administration proposed charging user fees to e-cigarette makers in its fiscal year 2020 budget released Monday, hoping to stop what outgoing Food and Drug Administration Commissioner Scott Gottlieb has called “an epidemic” of tobacco use among young people.

The proposal would add e-cigarette manufacturers and importers to the list of companies required to pay user fees to the FDA, and raise the amount of user fees that companies could be required to pay. Traditional tobacco companies already pay the fees.
