Ayahuasca Beyond the Amazon: the Benefits and Risks of a Spreading Tradition

Abstract

Ayahuasca, a hallucinogenic plant brew from the Amazon basin used as part of healing ceremonies by the region’s indigenous people for centuries, is now consumed by growing numbers of people throughout the world. Ayahuasca consumption has moved from strictly being part of indigenous shamanic healing ceremonies, to being a key component of the Brazilian syncretic churches formed in the last century, to most recently being part of ‘‘New Age’’ rituals conducted throughout the Western world. The discovery of ayahuasca by the Westerners, has resulted in a growing body of research suggesting that participants who take part in ayahuasca ceremonies experience significant spiritual and psychotherapeutic effects. Along with these potential benefits, however, the adoption of indigenous practices into Western cultures brings simultaneous challenges. As participation in ayahuasca ritual spreads into Western cultures, it becomes necessary to examine how to integrate these spiritual healing rituals into contemporary Western concepts of psychological health and ethical conduct.

Changes in Spirituality Among Ayahuasca Ceremony Novice Participants

Abstract

Ayahuasca, a hallucinogenic plant brew from the Amazon basin used as part of healing ceremonies by the local indigenous people of the region for centuries, is now being consumed by growing numbers of people throughout the world. Anecdotal evidence and previous research suggest that there are spiritual effects experienced among participants who take part in ayahuasca ceremonies. The current study examined whether novice participants’ spirituality was affected through participation in an ayahuasca ceremony, and if so, how. A mixed-design method was used, comparing those participating in an ayahuasca ceremony to those who did not participate. This investigation used the Peak Experience Profile, the Spiritual Well-being Scale, and the Mysticism Scale as quantitative measures. Participant interviews and written accounts of ceremony experiences were analyzed. Results showed that neither the SWB score nor the M-Scale score increased significantly after participating in an ayahuasca ceremony. However, it was found that the higher the PEP score, the greater the positive change in SWB and MScale scores. Qualitative data revealed common spiritual themes in many of the participants’ interviews and written accounts. Experiential differences were displayed within the ayahuasca ceremony group, warranting continued investigation into, and identification of, various confounding variables that prompt reported changes in spirituality within some participants while not in others.
