## Abstract

The Drug Enforcement Administration proposes placing beta- hydroxythiofentanyl (N-[1-[2-hydroxy-2-(thiophen-2-yl)ethyl]piperidin- 4-yl]-N-phenylpropionamide) also known as N-[1-[2-hydroxy-2-(2- thienyl)ethyl]4-piperidinyl]N-phenyl-propanamide including its isomers, esters, ethers, salts, and salts of isomers, esters and ethers, in schedule I of the Controlled Substances Act. 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 beta-hydroxythiofentanyl.
