The Food and Drug Administration’s legal rationale for regulating e-cigarettes as “tobacco products,” even though they do not contain tobacco, is that they deliver nicotine derived from tobacco. But e-cigarettes do not always do that. There are many varieties of nicotine-free e-liquids, sold in disposable e-cigarettes, replaceable cartridges and bottles for refilling vaporizer tanks. Do those liquids and the systems in which they are used also qualify as tobacco products?
