Wonderful that your freind has found the correct mushroom to use for that. What often happens with novice users of mushrooms is they choose poorly. I read of a case last year where this karate teacher ate ‘the wrong mushrooms’ and ended up trapped in a dream state, then ripping his friends heart out of the body. He is about 30 years old now, most likely to be locked up for life.
I still find it hard to believe people are stupid enough to do that stuff.... then again look who people elect
