Those biscuit and cornbread posts made me think of this for some reason. When I was in high school, I heard and read about people in prison making hallucinogens from rye bread.
The process, as I understood at the time, was to take a peice of rye bread, put on some kind of citrus fruit, and let it mold. I remember trying this with rye and orange juice concentrate, but only ended up with moldy bread stomach ache (suprised thats all I got).
I suppose this is all based on extracting erogot from the rye? Has anyone else heard of these myths/folklore tales? Is it possible to make a hallucinogen in this manner?
