The Hoasca Project
This project took place in Manaus, Brazil, in 1993. The study investigated 15 long term users of ayahuasca and 15 matched controls. The Hoasca Project established a model and precedent for the biomedical investigation of ayahuasca in it’s natural setting.
All the long term ayahuasca using subjects reported they had undergone a personal transformation following regular participation in ritual ayahuasca use. They reported a radical restructuring of their personal conduct and value system. Subjects emphasized the importance of “doing good deeds”, “watching ones words”, and having respect for nature. Subjects also reported having improvement in memory and concentration, persistent positive mood states, fulfillment in day-to-day interactions and a sense of purpose, meaning and coherence to their lives.
“improvement in memory and concentration, persistent positive mood states, fulfillment in day-to-day interactions and a sense of purpose, meaning and coherence to their lives.”
All subjects were members of the UDV church, and it is unclear how much influence the structure of their organization had on the results. However, the results showed only positive long term effects of consuming ayahuasca on a regular basis.
