The ancient, mystical, psychedelic drugs were likely very instrumental in human development. As the supplies of our early ancestors dwindled, due to ice ages and such, armies and borders had to be formed to protect the remaining ??sacraments?.

Alcohol replaced the mushrooms, and other natural chemical mind-enhancers. Things have been going downhill for humankind ever since, in many ways.

Terrence McKenna has written some very interesting books about this subject, which are detailed above ?? I have several of them, including True Hallucinations and Food of the Gods. I've read parts of his book, The Archaic Revival, also.

This man gave his life for inner-mind exploration - he probably overdid it with "heroic" doses of DMT, but was very serious about it.

I read The Sacred Mushroom and the Cross, by R. Gordon Wasson, many years ago. This was an interesting one, also. Wasson was a VP on Wall Street when he took up magic mushrooms as an interest!
