Sorry, no. There is no chemical solution to the mess our world is in. Alcohol is at least as natural as the psychedelics you advocate. I'm not advocating for alcohol either, incidentally. I don't drink.

"The risks associated with drug induced spiritual experiences are too great so it is advisable that people use natural methods to achieve such states. There is no spiritual experience that is produced by drugs that can’t be induced naturally. The problem that most people have with following a natural method is that it takes a good deal of time and energy. This is actually beneficial though, because it ensures that the individual is more ready for these experiences when they happen."
