I’m modeling it after the drug-discussion parts of the now-dead website 420chan.org, which I used a lot when I was younger. (Which, I feel like I have to give the disclaimer every time, was nothing like 4chan.)

c/Drugs is the main community, but for example from the perspective of me as a potential browser, I really only care about cannabis and psychedelics. So having specific communities for those substances is beneficial imo. Plus it’s so low-effort to moderate on Lemmy anyway, at least for now, that it’s really no struggle. Plus the community already exists anyway, might as well get it in working order.
