Chemical Names of Previously Controlled Fentanyl-Related Substances
The Drug Enforcement Administration (DEA) is providing additional descriptive information with respect to five specific substances already covered by a temporary scheduling order that appeared in the Federal Register on February 6, 2018. That order placed fentanyl-related substances temporarily in schedule I of the Controlled Substances Act. The order further stated that if and when DEA identifies a specific new substance that falls under the definition of a fentanyl-related substance, the agency will publish in the Federal Register, and on the agency website, the chemical name of such substance. Consistent therewith, this document provides the chemical names of five substances that fall within the definition of fentanyl- related substances that were temporarily controlled under the scheduling order issued February 6, 2018.
