Stopping Overdoses of Fentanyl Analogues Act

This bill amends the federal Controlled Substances Act to automatically classify all fentanyl-related substances as Schedule I drugs. It defines "fentanyl-related substances" to include any compound structurally similar to fentanyl through specific chemical modifications (like changes to rings or groups), covering isomers, salts, and derivatives. This means any new fentanyl analogues created by manufacturers would be immediately illegal without needing separate scheduling. The law directly affects drug manufacturers, distributors, and anyone possessing these substances, aiming to prevent new fentanyl variants from entering the market and causing overdoses.
