With the issuance of this final rule, the Drug Enforcement Administration places 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, bk-MBDB e); 2-(methylamino)-1-phenylpentan-1-one (pentedrone); 1-(1,3-benzodioxol-5-yl)-2-(methylamino)pentan-1-one (pentylone, bk-MBDP); 4-fluoro-N-methylcathinone (4-FMC, flephedrone); 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, whenever the existence of such salts, isomers, and salts of isomers is possible, into schedule I of the Controlled Substances Act. This 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. This rule continues the imposition of the regulatory controls and administrative, civil, and criminal sanctions applicable to schedule I controlled substances 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 4- MEC, 4-MePPP, [alpha]-PVP, butylone, pentedrone, pentylone, 4-FMC, 3- FMC, naphyrone, or [alpha]-PBP.
