The FDA is tied in knots over e-cigarette use. On the one hand, the FDA does not want people to smoke. But, on the other hand, the FDA does not want people to use smoking alternatives that could help them quit, such as e-cigarettes. To that end, the FDA recently signaled its interest in increasing regulation of e-cigarettes including Altria's MarkTen and British American Tobacco's Vuse, with an eye towards protecting teens from potential health effects.
