Shrooms helped me quit alcohol. Drank for 10 years every night, took shrooms twice in my life, never drank again after the second time. That was many years ago. I guess there are some things more useful than an accurate model of reality?
Ketamine is a great anti-depressant for people who are resistant to all other treatments, yet you don't see people going around indiscriminately praising the effects of ketamine like you do with LSD or shrooms.
