Cocaine never triggered mania with me. Neither have shrooms, which I tried maybe 3 times. Marijuana has induced psychosis, so I stay away from it, at least for now. The few times I have tried shrooms, I absolutely loved it. To me, it was like a short-lived hypomania, I only tried maybe 2 grams, I didn't hallucinate or anything, just saw colors very vividly, music was very intense, trees were amazing to look at. I believe magic mushrooms even helped with my depression freshman year. I opened up, and seemed to improve in my communication for the time. After I tried shrooms the first time, I even ended up in a girls dorm, I don't even know how it happened.
I would love to try it again, but idk.
As for lsd, I am afraid to touch that. I don't know if I'd be able to handle it and fear a bad trip. I've never had a bad trip on shrooms.
I have read much on Timothy Leary and when they were experimenting with psychedelics to improve mental health issues such as depression and whatnot. It's amazing what they can do. He said the first time he tried shrooms, in 5 hours he written two books, and discovered more about himself then he had his whole life up to that point. If interested, it's a good read.
