WHO Expert Committee on Drug Dependence. Thirty-second report.

This report presents the recommendations of a WHO Expert Committee responsible for reviewing information on dependence-producing drugs to assess the need for their international control. The first part of the report contains a general discussion of the new guidelines for the review of dependence-producing psychoactive substances and their implications for the scheduling of ephedrine and of the guidelines that were drafted to clarify the scope of control of stereoisomers. A summary follows of the Committee's evaluations of six substances (4-bromo-2,5-dimethoxyphenethylamine (2C-B), 4-methylthioamphetamine (4-MTA), gamma-hydroxybutyric acid (GHB), N-methyl-1-(3,4-methylenedioxyphenyl)-2-butanamine (MDBD), diazepam and zolpidem), four of which (2C-B, 4-MTA, GHB and zolpidem) were recommended for international control. The report also discusses the substances that were pre-reviewed by the Committee, five of which (amfepramone, amineptine, buprenorphine, dronabinol and tramadol) were recommended for critical review at a future meeting.
