## Abstract

The Drug Enforcement Administration proposes placing 10 synthetic cathinones: 4-methyl-N-ethylcathinone (4-MEC); 4-methyl- alpha-pyrrolidinopropiophenone (4-MePPP); alpha- pyrrolidinopentiophenone ([alpha]-PVP); 1-(1,3-benzodioxol-5-yl)-2- (methylamino)butan-1-one (butylone); 2-(methylamino)-1-phenylpentan-1- one (pentedrone); 1-(1,3-benzodioxol-5-yl)-2-(methylamino)pentan-1-one (pentylone); 4-fluoro-N-methylcathinone (4-FMC); 3-fluoro-N- methylcathinone (3-FMC); 1-(naphthalen-2-yl)-2-(pyrrolidin-1-yl)pentan- 1-one (naphyrone); alpha-pyrrolidinobutiophenone ([alpha]-PBP) and their optical, positional, and geometric isomers, salts and salts of isomers into schedule I of the Controlled Substances Act. This proposed scheduling action is pursuant to the Controlled Substances Act which requires that such actions be made on the record after opportunity for a hearing through formal rulemaking. If finalized, this action would impose the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances on persons who handle (manufacture, distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle 4-MEC, 4-MePPP, [alpha]-PVP, butylone, pentedrone, pentylone, 4-FMC, 3-FMC, naphyrone, or [alpha]-PBP.
