The proposal will be subject to public comment and further review by the agency before becoming final. But once that happens the rule would impose new restrictions, including:
A ban on the sale of e-cigarettes to minors.
A prohibition on distributing free samples.
A ban on selling e-cigarettes in vending machines unless they are in places that never admit young people.
A requirement that e-cigarettes carry warnings that they contain nicotine, which is addictive.
E-cigarette manufacturers would be required to disclose the ingredients in their products.
