Kudos to this comment for pointing out the addiction angle. There are definitely much more dangerous products being sold than even traditional cigarette, but hardly there is a legally marketed product more addictive than nicotine. The sale of such products should be strictly regulated, not only it because of the human costs but because it undermines the the principle of free market exchange when a customer is not at will to buy or not buy the product or alternatives. On the other hand the benefit of converting traditional smoker to e-cigs is undisputed.
