Nearly 75 years after the United Nations called for the abolition of coca leaf chewing, the world will have an opportunity to correct this grave historic error. The World Health Organization (WHO), at the Plurinational State of Bolivia’s request, and supported by Colombia, will conduct a ‘critical review’ of the coca leaf over the next year.
Based on its findings, the WHO may recommend changes in coca’s classification under the UN drug control treaties. The WHO recommendations would be submitted for approval by the UN Commission on Narcotic Drugs (CND), with voting likely in 2026. The Washington Office on Latin America (WOLA) and the Transnational Institute (TNI) will be monitoring the coca review process closely and examining key aspects of the debate. As part of this we are producing a series called “Coca Chronicles”.
The first issue of the Coca Chronicles discussed the current classification of the coca leaf in Schedule I of the 1961 UN Single Convention on Narcotic Drugs (or its effective ban) and Bolivia’s initiation of the WHO critical review process.
The second issue highlighted three developments during the March 2024 CND session: (1) support for the coca review from the UN High Commissioner for Human Rights; (2) Bolivia’s call to protect the coca leaf as a genetic resource; and (3) an update on the WHO’s preparations for the review.
In this third issue, Anthropologist Wade Davis gives us a deep dive into the history and significance of the coca leaf in the Andean Amazon region.
Wade Davis is a Canadian cultural anthropologist, ethnobotanist, photographer, and writer. He is professor of anthropology and the BC Leadership Chair in Cultures and Ecosystems at Risk at the University of British Columbia. He is a multiple award-winning author of more than 25 books, and has done extensive research into coca leaf, among many other ethnobotanic explorations.
