The Food and Drug Administration today proposed a new set of rules that will make selling e-cigarettes to minors illegal, regulating the $2 billion industry for the first time.

The public has 75 days to comment on the proposed rules, which would require e-cigarette manufacturers to report ingredients to the FDA and affix a label warning that they contain nicotine, which is addictive, to each product. The FDA would also prevent companies from selling e-cigarettes in vending machines (unless they are in a place where minors are not permitted entry) or distribute free samples, and set the national minimum purchasing age of e-cigarettes at 18.

The proposed regulations would constitute a huge and much-needed change, according to FDA Commissioner Margaret Hamburg, who said that "we will have the authority as a science-based regulatory agency to take critical actions to promote and protect the health of the public." Mitchell Zeller, head of the FDA's Center for Tobacco Products, added that "We call the current marketplace for e-cigarettes the Wild Wild West... we will be in a position to ensure that the products are as safe as they could possibly be."
