The forty-first meeting of the World Health Organization (WHO) Expert Committee on Drug Dependence (ECDD) was held from 12–16 November 2018 at WHO headquarters in Geneva, Switzerland.

Mr Justice Tettey made a statement on behalf of the UNODC. Scheduling of substances under the three international drug control conventions continues to be a cornerstone of the rule-based system of ensuring access to substances for medical and scientific use, while preventing their abuse. UNODC’s role in scheduling has been to facilitate Member States’ understanding of the procedures, and the scientific and technical reasons behind the recommendations of the treaty bodies. This is vital to ensuring effective implementation of scheduling decisions. UNODC continues to find value in engaging in the risk assessments carried out by WHO with regard to the 1961 and 1971 Conventions, and the International Narcotics Control Board (INCB) with regard to the 1988 Conventions, with support from their respective scientific advisory groups or expert panels, as appropriate and where possible. Since 2015, the CND has taken decisions to schedule 39 substances under the 1961 and 1971 Conventions, and to schedule two precursors of fentanyl and its analogues under the 1988 Convention.
