Did the rate of marijuana use meaningfully change, though? It's been abundantly available on the west coast for decades. The only thing that changed is who you buy it from, and to a certain degree who you have to hide it from.

Pot is very very different from lsd. And also I doubt legalization had a meaningful impact in usage rates.

For that matter, I suspect even if lsd were legal, I don’t think a lot of people would do it.

Back in the 90s when lsd was super cheap and everywhere on the east coast, most people didn’t do it. Even when I was going to raves a lot and hanging around with people who did a lot of drugs and sold drugs, most people did not do lsd very often. It’s an intense experience and a lot of people don’t find the idea appealing and don’t enjoy it when they try it.

Cannabis is not psychedelic, at least to the same degree that classical psychedelics are (Psilocybin, Mescaline, DMT).
