This sounds like he had some severe mental health issues that a really bad trip exacerbated. Also, one shouldn’t mix mushrooms with other substances unless you already know how it will affect you or at least in limited amounts, like a hit of weed to calm you down during the intense ‘come up’ of the shroom trip.

Also for every story of shroom induced psychosis resulting in injury, there’s thousands of pleasurable/therapeutic trips that take place without recognition. I think this guy may have a history of sexual abuse resulting in some serious issues. Gotta microdose my man!
