WHO Expert Committee on Drug Dependence: forty-fifth report

Overview

At its forty-fifth meeting, the ECDD critically reviewed nine new psychoactive substances, comprising one synthetic cannabinoid receptor agonist (ADB-BUTINACA), two benzodiazepines (adinazolam, bromazolam) four novel synthetic opioids (protonitazene, etazene, etonitazepyne, 2-methyl-AP-237) and two cathinones/stimulants (a-PiHP and 3-Methylmethcathinone). A critical review was undertaken of data on the use of each substance and its effects, so that
the Expert Committee could determine whether the information available on these substances justified scheduling in the 1961 or 1971 Convention. In addition, the meeting pre-reviewed zopiclone, to determine whether the current information justified a critical review.
