I took a lot of psychedelics over 30 some years, LSD, psilocybin, mescaline, peyote, mushrooms, morning glory seeds, and ayahuasca. I have no regrets. On balance, although I obviously overdid it, I believe it was good for me, but that may not be true for everyone.
I do believe psychedelics can be an effective treatment for despair, but I no longer believe they are a path to enlightenment. The bottom line is that psychedelics are neither necessary nor sufficient for salvation.
