HR 27 United States House · 119th Congress

HALT Fentanyl Act

The HALT Fentanyl Act (HR 27) creates a new category of Schedule I controlled substances for "fentanyl-related substances" defined by specific chemical modifications to fentanyl. This law directly affects researchers, medical professionals, and law enforcement by expanding the legal definition of fentanyl-related substances to include many structurally similar compounds. Key provisions include streamlined registration processes for research on these substances, allowing researchers to conduct studies with expedited procedures if related to FDA-approved drug development or government-funded research. The bill requires the Attorney General to issue implementing rules within six months and includes penalties for violations involving these substances.
