The Peyote Cult [EPUB ebook] 

A short book about the peyote drug. The book covers experiences of peyote users, their conversions, the ceremonies, and accounts of the leaders of the peyote. "In the middle of the night we were to eat peyote. We ate it and I also did. It was the middle of the night when I got frightened, for a live thing seemed to have entered me. "Why did I do it?" I thought to myself. I should not have done it, for right at the beginning I have harmed myself. Indeed, I should not have done it. I am sure it will injure me. The best thing will be for me to vomit it up. Well, now, I will try it. After a few attempts I gave up. I thought to myself, "Well, now you have done it. You have been going around trying everything and now you have done something that has harmed you. What is it? It seems to be alive and moving around in my stomach. If only some of my own people were here! That would have been better. Now no one will know what has happened to me. I have killed myself."
