Very interesting. I've smoked DMT, which I made from instructions on Erowid.org. Pretty easy to do. I'm sure an ayahuasca trip would be amazing. Traditionally, I think the songs/chanting done by the shaman and his crew are a core part of the experience. I'd definitely prefer to do it in that kind of setting, as opposed to making it myself.
Of the people who've done it in South America, or in a traditional setting, do you have any tips about finding a good shaman? I think with the growing popularity, there are a lot more scammy folks trying to cash in on the gringos going to the Amazon looking for an ayahuasca ceremony. That's definitely on my bucket list of things to do.
One of the most interesting things about ayahuasca is that it's ingesting DMT orally, and requires the mono-amine oxidase inhibitor to be orally active. Of all the thousands of plants in the Amazon, they figured out which two to mix together to make it work. How's that come about?
Erowid has some good stuff on DMT, and check out the book DMT: The Spirit Molecule by Rick Strassman, who's a psychiatrist from New Mexico who did the only clinical studies in the U.S. Also, lots of stuff by Terrence McKenna, if you're not familiar with him.
