Are there actually documented pages about people developing schizophrenia right after taking psilocybin mushrooms?

Yes, but rare: Psylocibin and lsd can trigger acute psychotic-like episodes but fortunately cases of ongoing schizophrenia afterwards are quite rare. Most authorities believe that those who have schizophrenia triggered by hallucinogens were predisposed to it and likely would have developed it anyway, but no one knows for sure.See http://www.Psychforums.Com/schizotypal-personality/topic26065.Html and my comment:.
