but what about the health benefits? isn't that the real bottom line we care about? not something arbitrary and meaningless like whether people completely stop smoking? isn't reducing smoking a good thing too? it does need some regulating though. the volume of nicotine in the default over the shelf vaping kit... you never get anywhere near to consuming as much as that smoking 20 a day of the strongest brands.

The volume of nicotine may be higher, but note that the 'nicotine content' marked on cigarettes is generally the amount considered to be available/absorbed, whilst the content marked on e-liquids is the total present. Whether the amount absorbed is higher I'd be interested to know. I suspect it depends quite strongly on the mechanism (tiny vape pen vs mech setup, how long vapour is held before exhaling, etc).

> the volume of nicotine in the default over the shelf vaping kit... I did the calculation myself and was shocked at how much nicotine was in the liquids, but after looking into it, I believe the nicotine absorption rate from vaping is much lower than from traditional cigarettes[0]: > Compared to smoking one tobacco cigarette, the EC devices and liquid used in this study delivered one-third to one-fourth the amount of nicotine after 5 minutes of use. New-generation EC devices were more efficient in nicotine delivery, but still delivered nicotine much slower compared to tobacco cigarettes. The use of 18 mg/ml nicotine-concentration liquid probably compromises ECs' effectiveness as smoking substitutes; this study supports the need for higher levels of nicotine-containing liquids (approximately 50 mg/ml) in order to deliver nicotine more effectively and approach the nicotine-delivery profile of tobacco cigarettes.

And it's not only about nicotine. Think about all the other harmful chemicals you inhale when you smoke a regular cigarette, and not when you smoke an e-cigarette. Such as tar, ammonia and arsenic.
