Gwern compiled an excellent assessment of nicotine as a supplement. https://www.gwern.net/Nicotine https://www.gwern.net/Nicotine This regulation is disingenuous and misinformed, if only because vaping solutions don't contain nicotine as a necessary component any more than bubble gum or throat lozenges do. The regulation seems to try to cover for this by including new rules for only other optional ingredients: its flavorings. Conflating it with tobacco smoking is their basis for passing as a protection measure for children, but it bears little in common, chemically or medically, with it. When ultrasonic models appear, they'll piggyback off of existing regulation to include them, but it'll be a bankrupt argument.
