This doesn't seem as unreasonable as your incredulity makes it sound. Alcohol is uncontroversially wayyy more dangerous than a handful of illegal drugs, and it's in incredibly wide usage. Same for cigarettes in the past: it took a sui generis effort to dramatically shift culture to lower cigarette's popularity (in the US), and it was fragile enough that a rebranding to "Juul" is starting to undo a lot of that work. FWIW, from a selfish perspective, I wish most drugs were legal: ; I used marijuana responsibly before it was legal and continue to use psychedelics responsibly, and the reason I don't do meth or cocaine isn't because it's difficult to get, but because I'm aware of how dangerous they are. But I'm genuinely curious as to what could make you think that, for the average person, legality doesn't drive a substantial amount of their attitudes towards usage of a given drug.
