I happened to come across an interesting show on the travel channel last night called Madventures. I guess it's a new show but anyhow the first one is these two guys and they go somewhere in Brazil and drink Ayahuasca. The part where they trip isn't all that interesting but the show itself was and it was pretty clear that they knew what they were talking about. They definately did their homework on the subject and it was pretty informative. Not to me or probably anyone else here but they did produce an informative show on the subject of ayahuasca and had nothing bad to say about it and even shot down some stereotypes of Hallucinogens.
I didn't see any other threads on this subject in the few forums I thought that it would be found so if there is one I apologize.
Here is the entire clip. Not with english subtitles though which are helpful because he is a bit hard to understand.
