Long-Term Effects of the Ritual Use of Ayahuasca on Mental Health
José Carlos Bouso, PhD
Abstract: Over the last decades, ayahuasca use has expanded throughout the world. An uncountable number of people are being exposed to this potent hallucinogenic beverage. At the same time, little is known regarding the long-term effects of ayahuasca use. The few studies published until now conclude that ayahuasca seems not to be deleterious at the long term. In this presentation, data will be presented from a longitudinal study where different areas of mental health have been assessed in a large sample of regular ayahuasca users (N = 127) and controls (N = 115). The assessment included potential drug abuse-related problems, personality, psychopathology, life attitudes, and neuropsychological performance. Results are in line with previous studies. Potential biases shared by all the published studies will also be discussed.

He also has been conducting neuropsychological research into the long-term effects of drugs such as cocaine and cannabis. He has done transcultural research, extensively studying the long-term effects of ayahuasca use in different cultures and ecosystems, both in Spanish and in Brazilian communities.
