Having successfully completed two month-long ayahuasca intensives at Wasiwaska (http://www.wasiwaska.org), Luis Eduardo Luna's facility in Brazil, I recommend the experience to anyone with a serious interest in this traditional Amazonian medicine. My partner and I had initially experienced Luna's version of the ayahuasca ceremony at the Psychointegrator Plants Seminar in Manaus in July 2000, and attended the first Wasiwaska intensive in October 2001.
