Shrooms

This is from an article about amanita mushrooms, and it reminded me of the Fremen Water of Life ritual in Dune...but way grosser...

"In eastern Siberia, the shaman would consume the mushrooms, and others would drink his urine. This urine, still containing active hallucinogens may actually be more potent than the A. muscaria mushrooms with fewer negative effects, such as sweating and twitching, suggesting that the initial user may act as a screening filter for other components in the mushroom."
