WHO Expert Committee on Drug Dependence: forty-fourth report

Overview

The Forty-fourth WHO ECDD critically reviewed five new psychoactive substances: including one synthetic cannabinoid receptor agonist (4F-MDMB-BICA), two novel synthetic opioids (brorphine; metonitazene), and two cathinones/stimulants (eutylone; benzylone). A critical review to consider international scheduling measures was undertaken for each substance so that the Expert Committee could consider whether information about these substances may justify the scheduling or a change in scheduling of a substance in the 1961 or 1971 Conventions.
