In response to claims made in 2010 by the United Nations International Narcotics Control Board (INCB) regarding the serious health risks that would entail the use of ayahuasca, psychologist and ayahusaca researcher Jose Carlos Bouso has compiled a document with all the scientific studies into the short, medium and long term effects of ayahuasca. No study supports the claims of the INCB, and some of these studies even indicate a possible therapeutic potential of ayahuasca.
The document was published by the International Center for Ethnobotanical Education, Research and Service (ICEERS), and can be downloaded here.
