WHO Critical Review of Coca Leaf A Comprehensive Overview
Nearly 75 years after the United Nations called for the abolition of coca leaf chewing, a real opportunity to correct this is now underway. The World Health Organization (WHO), at Bolivia’s initiative and supported by Colombia, is currently conducting a ‘critical review’, a procedure designed to reassess if coca is appropiately scheduled in the 1961 UN Single Convention, and its findings may result in changing the coca leaf’s classification. The WHO recommendations will be submitted for approval to the UN Commission on Narcotic Drugs (CND), with voting likely taking place in March 2026. Here you can find all relevant information and documentation related to this review.

Consultations in Bolivia, Colombia and Peru
During 2024 TNI and its partners in Bolivia, Colombia and Peru, organised consultations on the critical review of coca by the WHO and its potential consequences. A total of 10 meetings were organised, with around 400 participants. The participants consisted of coca farmers, most with native indigenous roots, academics and coca experts, human rights activists and representatives of Indigenous Peoples of the Andean-Amazon region. In the case of Peru several initiatives were taken, by farmers organisations and academics, to call on the government to support the efforts to declassify the coca leaf.

Legal status and criminalisation
In the neighbouring countries of Peru and Bolivia, where coca has been part of daily life for centuries, coca use has increased over the last decades. In Argentina in particular coca chewing has a firm place amongst the population of the Northern provinces, and also Chile has coca consuming Indigenous and non-Indigenous populations. In other Latin American and European countries migrants from the Andean region bring their habits of coca use with them when moving across borders and are regularly confronted with criminalisation.
