Fascinating... But... I am very squiffy about this kind of stuff.
What stuff?
Psychadelics in general. Just because humans have been getting high for a really long time doesn't mean that it is a good thing to do so.
they are powerful openers but don't have the durability of meditation and prayer
they can actually become a liability to a person's advancement because they literally are reset switches for your paradigms, and very many contexts in which people take them are either random or maliciously crafted
