DEA Temporarily Adds All 'Fentanyl-Related Substances' to Schedule I of Drug List

The Drug Enforcement Administration is extending its listing of all “fentanyl-related substances” to Schedule I of the Controlled Substances Act, it said. The agency's temporary scheduling order, which covers “any substance not otherwise controlled in any schedule,” including substances not yet developed as of publication of DEA's notice, “that is structurally related to fentanyl” in certain ways, had been set to expire Feb. 6, 2020. But a law passed that day extended the temporary listing until May 6, 2021, the DEA said.
