If the public benefit is that current tobacco-smokers will switch, then the experience only needs to be better than cigarettes - broad appeal beyond that is only a net negative for society.
I put up with it like I accept that people fart. Being around “vape smoke’ is something between discomfort and disgust (smell, smoke, etcetera), Ugggh. Yes: I have close friends that vape. No: I don’t complain to them or make faces or anything.
Even if I were hypothetically shown it was a purely nonsensical psychological dislike, that doesn’t mean I could stop disliking it.
I think there is great value in considering this possibility, and all others. The problem I am trying to get at is that people have a tendency to not be terribly interested in what is true.
