Are electronic cigarettes approved by the FDA and the TTB?
The Alcohol and Tobacco Trade Bureau (TTB) and the Food and Drug Administration (FDA) have formally stated that Crown7 (one brand of electronic cigarettes) is not a product that warrants the involvement or oversight of either government entity. The FDA notes that Crown7 do not fit the classification of products it governs. The TTB (Tobacco and Taxation Bureau, formally the ATF, Alcohol Tobacco and Firearms) has formally determined that the TTB has no regulatory interest in Crown7 because it does not contain tobacco.
