## Abstract

The Drug Enforcement Administration places 1-(1,3-benzodioxol- 5-yl)-2-(ethylamino)pentan-1-one (known as N-ethylpentylone or ephylone) and its optical, positional, and geometric isomers, salts, and salts of isomers whenever the existence of such salts, isomers, and salts of isomers is possible, in schedule I of the Controlled Substances Act. This action makes permanent the current 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 N-ethylpentylone.
