Very cool writeup on witchcraft. I was watching TV last night and ran across a show about mushrooms. I learned something interesting which I thought I would pass on as it seems like it would fit well... There is a mushroom in Russia (it's a bright red mushroom with white spots on it... funny enough, looks like the mushrooms that little garden gnomes sometimes hold). Anyway, it has three active substances... two are psychoactive and another is slightly poisonous. The shaman would eat the mushroom. His liver (or maybe it was his kidney) would filter out the toxic substance and his disciples/apprentices would drink his urine so that they could get the benefits of the psychoactive substances without the ill effects of the toxins... just thought that was cool. :)
