the jage letters

I have just finished the book the yage letters by William Buroughs and Allen Ginsberg. This is a book of letters between Burroughs and Allen as they search for yage in South America. Yage is some kind of vine that is used as a drug. When Burroughs first finds and takes it, he starts vomiting and almost ODs. Scoring yage didn't look to be so much fun, but I guess that these things have to be experienced. I now want to travel in South America, but I doubt that it is very safe. I should do more research than watching the film city of god. (None of the yage letters is set in Brazil). The junkies in the 1950s were very literate, almost stylish.
