I think that the nature of Lemmy attracts people who are drawn to seek out new experiences and alternative lifestyles, so it’s less that psychs are widely popular and more this community has a higher percentage of users. That said, I don’t know anybody that does acid on the regular anymore, it was pretty uncommon when I was a teen, and the people who I know who like to trip (usually hippies, ravers, and punks) are typically doing shrooms. Might also be because I live in shroom country so they’re easy to find and cheap if you have to buy them. Gotta say, a few days in the middle of the backcountry with a dose it nice, I can’t imagine doing it and going to the bar on a weekend.
