Well, I guess it’s not only that. Psychedelic drugs can really fuck you up, if you aren’t prepared. People talk about set and setting a lot.
I suspect that these drugs sure help a lot of people, but can also fuck a lot of people up really badly. It’s like, people who don’t go along well with these substances, avoid them instinctively.
Now, if someone would prescribe them, I’m pretty sure that a lot of people who are simply not prepared for it mentally (instead blindly trust the medics), would take them and get hurt pretty badly because of that.
