I've done video's on the Ayahuasca topics you discuss with Max. I've been down to Peru 3x for an apprenticeship with my Shipibo Maestro. The tourism was started by literally just 2 guys in the 90's. One of the 2 was a journalist that wrote for a big magazine..like BIG. After an article or 2 being written about it, BOOM, tourism abounds. I hung out with those 2. One runs a small(er) Ayahuasca center outside of Iquitos and the other runs trips from the states to the jungle, down the rivers to a tribe he has a special relationship with. I've seen the inside of the ayahuasca industry and it's full of fucked up people...and strangely enough, they've all drank, a lot. Ayahuasca doesn't change someone that doesn't want to do the work on themselves. Hell, Brujo's drink Ayahuasca and they're considered to be the "evil" wizards/sorcerers/witch doctors - doesn't make them any more morally sound or "enlightened" in a good way. Ayahuasca is BEAUTIFUL but she is generally a catalyst for the passajaro...she'll damn sure help people to shift their perspective. peace!!
