Ayahuasca is a psychoactive substance that has long been associated with indigenous Amazonian shamanic practices. The recent rise of the drink's visibility in the media and popular culture, and its rapidly advancing inroads into international awareness, mean that the field of ayahuasca is quickly expanding. This expansion brings with it legal problems, economic inequalities, new forms of ritual and belief, cultural misunderstandings, and other controversies and reinventions.

In The World Ayahuasca Diaspora, leading scholars, including established academics and new voices in anthropology, religious studies, and law fuse case-study ethnographies with evaluations of relevant legal and anthropological knowledge. They explore how the substance has impacted indigenous communities, new urban religiosities, ritual healing, international drug policy, religious persecution, and recreational drug milieus. This unique book presents classic and contemporary issues in social science and the humanities, providing rich material on the bourgeoning expansion of ayahuasca use around the globe.
