Contact Congress about S. 331: HALT Fentanyl Act

The bill would put many fentanyl-like drugs under the strictest federal drug rules. It would also make some research approvals faster and more flexible. Most changes would start right away.

Modern Action explains legislation in plain English, helps you choose whether to support, oppose, or ask for changes, and drafts a message tied to the bill, your stance, and the elected officials who can act on it.

HALT Fentanyl Act is a Senate bill signed into law. The latest recorded action: Became Public Law No: 119-26.

Latest action on S. 331: Became Public Law No: 119-26.

Who this affects: This bill mainly affects people who make, sell, import, or export fentanyl-like drugs, because more substances would fall under strict federal drug rules. It also affects federal law enforcement and prosecutors, who would have clearer authority over many fentanyl variants. Researchers who study fentanyl or other Schedule I drugs could see faster approvals and fewer separate registrations. The Attorney General and the Drug Enforcement Administration would have to write and run the new process.

Why this matters: Fentanyl-like drugs can appear faster than drug laws can name them one by one. This bill tries to close that gap by controlling a whole class of related substances. That could help law enforcement act sooner against new fentanyl variants. It could also bring harsh penalties to more substances before their risks or possible medical uses are fully known. For researchers, the bill could reduce delays, but the final process will depend on later federal rules.

Key provisions in S. 331

  • The bill creates a new Schedule I category for fentanyl-like drugs. A substance fits if it is chemically related to fentanyl in the listed ways, unless another federal rule already controls it differently.
  • The Attorney General may publish a public Federal Register list of fentanyl-related substances. But a drug does not have to be on that list to be controlled if it fits the definition.
  • Fentanyl-related substances would face the same federal trafficking and import-export penalties as fentanyl analogues. These penalties are in the federal drug laws for trafficking and drug imports or exports.
  • Some Schedule I research could use a faster notice process. This applies to Food and Drug Administration investigational drug work, or research run or funded by Health and Human Services, the Defense Department, or Veterans Affairs.
  • A new researcher who sends a complete notice must get an answer within 45 days. The Attorney General must either grant the research registration or start a formal process to challenge it.
