## Abstract

This rulemaking corrects Title 21 Code of Federal Regulations (CFR) by deleting regulations which list the substances benzylfentanyl and thenylfentanyl as being temporarily subject to schedule I controls under the emergency scheduling provisions of the Controlled Substances Act (CSA). The temporary scheduling of benzylfentanyl and thenylfentanyl expired on November 29, 1986. DEA determined that these compounds were both essentially inactive, with no evidence of abuse potential. As such, these compounds are no longer schedule I controlled substances and all references to these compounds are being deleted from DEA regulations.
