Within ancient religions the use of drugs were to tap into the spiritual realm. Psychotropics hallucinogenic plants were only used in religious ceremonies. Some ancient civilizations guarded these herbs, fungi, and potions with strict laws. Prohibiting the use or handling by anyone other than the priest or priestess of the group. While some may come to give reasons for the benefits of these drugs, the truth is this, they open gateways to places where almighty God didn't intend us to go. Even the ancient Shaman would be agast, to see a people using these substances without their religious guidance. Yet, Christianity isn't a religion which uses the vehicle of the psychotropic hallucinogen. We pray, we reach out to God without the "shortcut" of the psychotropic hallucinogen. Which the shortcut doesn't take us to the God, but to a god, or gods which don't help us get better, but worse.
