Stopping Overdoses of Fentanyl Analogues Act

Sponsored by Scott FitzgeraldRep. Scott Fitzgerald (R-WI)
Introduced March 26, 2021

AI-Generated Summary

Updated February 8, 2026 at 1:05 AM UTC

The Stopping Overdoses of Fentanyl Analogues Act amends the Controlled Substances Act to place a range of fentanyl‑related chemicals into Schedule I, the category for substances with high abuse potential and no accepted medical use. It adds several specific fentanyl analogues to the schedule and creates a broad definition that captures any material containing these substances or their salts, isomers, or derivatives. The change affects manufacturers, distributors, and anyone handling these chemicals, making them subject to the strictest regulatory controls.

Key Provisions

  • Adds five named fentanyl analogues (Isobutyryl fentanyl, Para‑Methoxybutyrylfentanyl, Valeryl fentanyl, Cyclopentyl fentanyl, Para‑Chloroisobutyryl fentanyl) to Schedule I.
  • Defines “fentanyl‑related substances” to include any compound structurally related to fentanyl by specified chemical modifications and lists additional specific analogues (e.g., 4'-Methyl acetyl fentanyl, Crotonyl fentanyl, etc.).
  • States that any material, mixture, or preparation containing any fentanyl‑related substance—or its salts, isomers, or salts of isomers—is automatically placed in Schedule I unless specifically exempted.
