However, there is quite a bit of research available [0, 1] that suggests that an addiction to one substance can prime the brain's neurological pathways to more easily become addicted to a second, unrelated substance.
By reducing the use of addictive substances overall, it might produce some decrease in addictions to more damaging substances (i.e. meth, heroin, etc).
Of course, the same argument could be said about alcohol or caffeine, and I don't think we're likely to see those go away any time soon. However, I think that's a false dilemma fallacy, as we're much closer (in % of population, at least) to reducing the use of nicotine than either of those.

Got any evidence for that assertion? Just saying it doesn't make it true, and the big problem with this research area is there are two different powerful groups (tobacco copmanies and public health policy makers). So the entire literature needs to be treated with great care. David Nutt, the british addiction specialist is a sober, sensible guy, and I'd go to what he has to say about it as a first port of call.
So, we worked for decades to eliminate cigarette dependency, made huge progress, and now kids largely don't smoke. And then vaping came along, and a company is receiving billions from investors to get kids addicted to nicotine.
Vaping is healthier, but I can't think of a conceivable reason why this is a good idea.
If a kid picks up a nagging but ultimately harmless nicotine habit, is that really the end of the world? Given what we know so far about vaping and its safety, I'd say you could make an argument for the pleasure of flavored nicotine outweighing the annoyance of addiction.
Even if there was, traditional cigarettes are on their way out, and what we are left with is something as dangerous as coffee and a bit more expensive.
Do you have evidence of this? From what I've read (the report I saw last had data in 2016), e-cig use is way up but general tobacco use among youth hasn't significantly changed.
But doea the harm reduction to pre-existing smokers outweigh the increased uptake in youth populations?
I think this was the initial hope for e-cigs, but reality has turned out differently. These things are leading to a whole new generation of nicotine addicts at a time when smoking has fallen to all time lows in the US. Juul particularly is getting kids hooked that otherwise would have never touched tobacco, and they're getting a lot of heat over their advertising tactics now.
