The Commission on Narcotic Drugs (CND) was established by the Economic and Social Council (ECOSOC) resolution 9(I) in 1946, to assist the ECOSOC in supervising the application of the international drug control treaties. In 1991, the General Assembly (GA) further expanded the mandates of the CND to enable it to function as the governing body of the UNODC, and to approve the budget of the Fund of the United Nations International Drug Control Programme, which accounts for over 90 per cent of the resources available to the United Nations for drug control. In ECOSOC resolution 1999/30, the CND was requested to enhance its functioning by structuring its agenda into two distinct segments: a normative segment, during which the CND discharges its treaty-based and normative functions; and an operational segment, during which the CND exercises its role as the governing body of UNODC.
