FDA Tackles Underage E-cigarette Use.

In recent weeks, the FDA has taken steps to address underage use of e-cigarettes: The agency has identified and warned retailers selling to minors, issued warning letters to companies selling e-cigarette cartridges in adolescent-appealing packaging, and requested information from e-cigarette companies. The steps are part of the FDA's ongoing effort to prevent middle- and high-school students from using e-cigarette products.
