As the debate over the health risks of e-cigarettes rages on, the FDA is stepping in to "improve public health and protect future generations." To do that, the US government will regulate e-cigs and vaping gear like it does any other tobacco product. Until now, these products haven't been subject to government oversight. With the FDA's changes, the federal law that already forbids tobacco sales to people under 18 will now apply to vaping as well. Sure, this age limit was already being enforced in some places, but this more formal announcement makes it a nation-wide law.
