The World Health Organization (WHO) has concluded one of the most significant processes in recent years in the field of international drug policy: the critical review of the coca leaf. The result confirms its continued classification in Schedule I of the 1961 Single Convention, the most restrictive level of the international control system. The recommendation, issued by the Expert Committee on Drug Dependence (ECDD), thus consolidates a framework that many actors considered susceptible to correction after decades of scientific, legal, and cultural questioning.
