> it got out of control, then people quit

Can confirm, that's how it went for me and at least a few friends who I've talked to about it. I went from rarely drinking to heavily drinking to now drinking even more rarely. I let it get way too out of control (mostly in frequency, nothing life-destroying or dangerous to anything/anyone but my body potentially) and even after admitting it was an issue it took a while before I kicked it. Glad I did. It made me look at drinking in a whole new light, especially about just how pervasive it is in society. The joke I've heard a number of times before along the lines of "It'd never get approved if it was introduced today" feels pretty apt. Even something like marijuana seems many times safer than alcohol.
