Interesting places for inspiration

I was watching a doc on the History Channel about psychedelic drugs and the film maker was studying a Native American tribe that uses peyote in some of their rituals. The film maker was influenced by a mentor of his, an anthropologist who did the same thing in the 1930's. The film maker interview people from the tribe and then participated in the ritual which consisted of him getting into a sweat tent, then take peyote. Because the rituals were so sacred, they did not allow cameras to film them. The film maker was very respectful with everyone and I did not get the impression that he was exploiting anyone. He respected their wishes about what can be filmed and not filmed. I was watching this with my sister and I comment that this is the kind of issues we studied in our Tools for World Theatre class, and explained to her that in the class we examined how we approach people and cultures different from us. She couldn't understand at first why I was interested in a culture that advocates using psychedelic drugs as part of their religion. I explained that I am interested as a theatre artist in a accurate portrayal of another culture and how I could use it as a theatrical piece since the rituals were indeed a piece of theatre.
