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 can see this happening - maybe once marijuana or other recreational drugs become state or federally legalized.
