excessive alcohol consumption. I'm not saying I think there will be prohibition, but maybe it won't be so normal to get almost blackout drunk, or everyone drinking at parties to be the norm.
I think the increase in really good tasting non alcoholic beer and spirits is telling.
I quit drinking last September and it was the best thing for my mental and physical health I ever did. Lemmy.world/c/stopdrinking has so many people who quit drinking for reasons other than hitting rock bottom.
I would say also the rise of really good alcoholic drinks too. Less mindless drinking, less alcoholism. I agree with this answer, the trend is already started. But think people will always want to get high in some way, do not think total sobriety is likely.
It's one small thing to be thankful for. At the same time that I started losing my tolerance and drinking went from "yea!" to straight "blech", sober curious became more of a trend. Any decent bar/restaurant will have a (good!) mocktail or two, and non-alcoholic beer really has lagers and IPAs figured out.
And I don't feel like there's any social pressure or scrutiny over what I'm (not) drinking.
