FYI, same goes for SSRIs. The scientific consensus is that the serotonin deficiency theory of depression was wrong. When SSRIs actually work, we still don’t know why.
I’ve had bad trips, too. Very bad, but I still think that psilocybin (in a controlled, supportive setting) is a better bet. My bad trips were all due to being in bad settings and being completely unprepared for what could go wrong. I was young and dumb and just fucking around. But tripping in positive supportive settings was incredibly helpful. And if we do find a way to do this right, then people don’t have to take drugs for the rest of their lives. Psychiatric drugs are generally lifelong sentences, and negative side effects tend to compound over time, which often leads to polypharmacy, and more side effects.
