Abstract: Ayahuasca is a medicinal plant mixture utilized by indigenous peoples throughout the Amazon River basin for healing purposes. This medicine contains a combination of monoamine oxidase inhibitors (MAOI’s) and N,N-dimethyltryptamine (DMT). When ingested together, these medicines produce profound alterations in consciousness. Ayahuasca is increasingly being explored as a treatment for addictions. However, the possible mechanisms of action by which ayahuasca treats addictions remain unknown. We propose four hypotheses regarding ayahuasca’s biochemical, physiological, psychological, and transcendent effects that may help explain ayahuasca’s anti-addiction effects.
