I'm interested in a scientific study of how it was somehow linked to spiritual. I'm aware of drugs in general changing mental states of people that suffer from different illnesses. I've tried shrooms before and the high was similar to cannabis for me. I'm not a spiritual person at all and maybe that is why I didn't really care for it. I can imagine psilocybin helping a person in general from the effects but I just don't understand why someone would link it to spiritual unless they were deluded.
