To clarify to everyone, I was talking about all drugs. Pharmaceuticals are bullshit for the most part as well, IMO. As someone who has used assorted ADHD, anti-anxiety, anti-depressant, and anti-psychotic medication for years, on top of extreme psychedelic abuse at points in my life, I think my viewpoint is legitimate. I've had numerous mental and physical problems from taking all classes of drugs, and the only thing that has consistently made me better is completely abstaining from everything and dieting/exercising correctly. I'm not saying taking a bunch of drugs doesn't work for some people, but certainly not for me.
Also, I'm well aware of the studies regarding cluster headaches and psilocybin, but I think it's a bad idea to experiment with such a new-fangled techniques especially when both drugs in question are affecting neurotransmitters similarly. As liquid sunshine said, cluster headaches are pretty damn uncommon (wiki says less than 0.1% of the population) and I don't think that a couple of uses of a drug could be a catalyst for them. I feel like it's more likely that there is something else insidious about the hardly researched JWH class of drugs and we just don't know about it yet.
Also, mushroom potency is highly, HIGHLY variable. I don't think the OP wants to take .5 and trip his nuts off while he's having an episode, sounds like a recipie for disaster. Also, OP mentioned not smoking weed (a much more mild and less axiogenic psychedelic) anymore ever since because of the pain; I don't see how taking a stronger psychedelic with variable potency is a great idea.
Am I really alone here?
