An electronic cigarette (or e-cigarette) is designed to look like a cigarette.
When you puff on it, instead of inhaling smoke, you inhale a mist of liquid, flavorings, and nicotine.
There is no published research to suggest that these products work for helping an individual quit smoking.
Since 2009, FDA has regulated cigarettes, smokeless, and roll-your-own tobacco. Effective August 8, 2016, FDA has finalized a rule to regulate all tobacco products to include: hookah, e-cigarettes, dissolvables, smokeless tobacco, cigarettes, all cigars, roll-your-own tobacco, pipe tobacco, and future tobacco products that meet the statutory definition of a tobacco product.
