Following a 2014 informal scientific consultation facilitated by NIDA Director Nora D. Volkow, M.D., and requests by United Nations member states, the United Nations Office on Drugs and Crime (UNODC) has created an Informal International Scientific Network to enhance collaboration between member states and scientists on the issues of drug use and addiction. NIDA International Program Director Steven W. Gust, Ph.D., and two former NIDA Hubert H. Humphrey Drug Abuse Research Fellows will serve on the panel and participated in the inaugural meeting of the network March 10–11, 2015, in Vienna, Austria. The former NIDA Humphrey fellows are Suzan Ben Ezra, who leads the Treatment and Rehabilitation Division of the Israeli Anti Drug Authority, and Jallal Toufiq, who directs the Moroccan National Centre on Drug Prevention, Treatment, and Research. The network will serve as a resource for UNODC, the Commission on Narcotic Drugs, and member states as they prepare for the 2016 United Nations General Assembly Special Session on the world drug problem. The Network members represent a wide range of drug abuse research disciplines and global regions.
