today i went to watch a documentary called little saints, eat a mushroom, this was produced by the friend of a friend of mine, the documentary is about the ritual of mushroom intake that happen in Oaxaca, mexico, i didnt knew that this healers as they are called have a mixed ritual based on catholicism and they suggest you pray to god and other saints while you are under mushy effect, this approach was very weird to me because results in a paradox where religion says you shall not use any substance that may harm or alter your conciousness and this healers mixing mushymushy with god.
the documentary focus on the very ritual on 5 persons ans is very explicit of how they react to it and the healer helping them to go through this experience, it does not have a scientific part of how does the psylocibin interact with the body, but if you are interested in knowing more about how mushrooms are procured by the healer to an unexperienced user, you might take a look at this.
