The Acting Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic cannabinoids (SC), ethyl 2-(1-(5-fluoropentyl)-1H- indazole-3-carboxamido)-3,3-dimethylbutanoate (trivial name: 5F-EDMB- PINACA); methyl 2-(1-(5-fluoropentyl)-1H-indole-3-carboxamido)-3,3- dimethylbutanoate (trivial name: 5F-MDMB-PICA); N-(adamantan-1-yl)-1- (4-fluorobenzyl)-1H-indazole-3-carboxamide (trivial names: FUB-AKB48; FUB-APINACA; AKB48 N-(4-FLUOROBENZYL)); 1-(5-fluoropentyl)-N-(2- phenylpropan-2-yl)-1H-indazole-3-carboxamide (trivial names: 5F-CUMYL- PINACA; SGT-25); and (1-(4-fluorobenzyl)-1H-indol-3-yl)(2,2,3,3- tetramethylcyclopropyl) methanone (trivial name: FUB-144), and their optical, positional, and geometric isomers, salts, and salts of isomers in schedule I. This action is based on a finding by the Acting Administrator that the placement of these SCs in schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, 5F-EDMB-PINACA, 5F-MDMB-PICA, FUB- AKB48, 5F-CUMYL-PINACA or FUB-144.
