If you're curious about the ties between religion, shamanism and psychedelics theres a great book by Terrence McKenna on this subject called Food of the Gods: https://www.amazon.com/dp/0553371304?psc=1&ref=ppx_yo2_dt_b_...

Terrance McKenna entertained us with the theory that psilocybin catalyzed human language "on the mushroom dotted plains of Africa".

I recommend “Food of the Gods” https://www.amazon.com/Food-Gods-Original-Knowledge-Evolutio... to anyone that’s interested in what role magic mushrooms may have played in the evolution of humans. It also does an interesting job in talking about what drugs are legal and what drugs are illegal (and the somewhat arbitrary demarcation line between what’s socially acceptable (alcohol, caffeine, sugar, tobacco) and what is not and will put you behind bars).

Take it w/ a grain of salt but it’s definitely thought provoking.

Also keep in mind that it was written in 1993 but does a pretty good job of anticipating the legalization of marijuana and the eventual decriminalization of moslty all drugs on Schedule I that were put there without any kind of research or backing data (psilocybin, DMT and friends)
