The VNGOC is a coordinating body for non-governmental organizations (NGOs) around the world concerned with problems related to substances controlled under the three international drug control treaties. The purposes of the Committee include, inter alia:

a) Supporting the activities of NGOs, and promoting contacts and collaboration with the United Nations Office on Drugs and Crime (UNODC), the International Narcotics Control Board (INCB), the UN Commission on Narcotic Drugs (CND), and other relevant UN agencies, offices and fora.
b) Promoting activities that lead to enhanced communication, cooperation and scientific, cultural and social exchanges between NGOs, UN agencies and member states.
c) Promoting increased awareness about issues relating to controlled substances through the dissemination of news and information.
d) Facilitating the representation of NGOs reflecting the broadest possible range of perspectives and groups involved, including affected populations. The VNGOC was established in 1983, and is a legally registered not-for-profit corporation under Austrian law. The VNGOC office is registered in Vienna, although the Committee operates globally.
