Has anybody come across any studies with adverse outcomes with psilocybin? I've heard of HPPD (hallucinogen persisting perception disorder) though it's somewhat rare. The benefits seem overwhelmingly positive.
Obviously the benefits is a fleeting and difficult to pin down thing. Outside of a clinical setting, experiences with psychedelics range from life-changing to life-destroying, with most people seemingly in the middle with "it's just fun". It certainly does not seem reliable.
I had actual HPPD for about a year after my trip, e.g. I could reproduce certain visual effects by looking in a certain way. I think it also caused my tendency to experience pretty strong open-eye hallucinations while meditating, which are called "makyo" in Japanese.
Of course, maybe none of this is due to the LSD usage, but I think some of it probably is.
After my 2 LSD trips with 100ug and very good setting (and I thought at the time good enough set) I slowly became very depressed and suicidal and had a total crisis. I actually had to seek out religion (which I always hated as a life long atheist) to be able to cope and not kill myself. It got close at some point and basically every since suicide has been lingering over my head. It made it a possibility: before LSD if I had stress I would lament at the world being unfair or something, after LSD if I have stress (even just minor work stress) I just can't stop thinking about killing myself. I'm on a waiting list for therapy but it is very long.
The absurd part about the LSD community is that even after telling other psych users all that, the response of about 50% of people is that I should take more at a higher dose...
