Stopping Overdoses of Fentanyl Analogues Act

New federal controls on fentanyl-like drugs

This bill would add a broad class of fentanyl-related chemicals to federal Schedule I. It would use five structural tests to define which chemicals are covered. Any material, compound, mixture, or preparation with any amount of those substances—including isomers, esters, ethers, and salts—would be treated as Schedule I unless specifically exempted or already listed in another schedule. If enacted, the change would take effect one day after enactment.
