In the context of the alternative which was “nobody really smokes or vapes” it’s not really a good outcome.
Sure, smoking rates cratered. It was great. But now vaping rates have gone up and it just didn’t have to happen that way at all.
Go back a few years and less people vaped with similarly low smoking rates. Vaping didn’t replace smoking, its net new usage.
I'm not sure this is actually bad. Nicotine, when divorced from the tar of burning cigarettes, has a number of desirable affects on alertness and appetite (as well as less desirable effects like increasing blood pressure) - it's not clear to me that avoiding nicotine as a stimulant is always desirable.
As well, vaping is so much less obnoxious to the people around you than traditional smoking (either tobacco or marijuana). I'm in favor of a lot of the social and legal pressure that has been put on smoking tobacco in public (and I think it should apply to weed as well despite being pro-legalization). But most of the actual issues go away if it's vaping and of smoking (and all of them go away if you're getting your tobacco via a pouch).
