HALT Fentanyl Act

The HALT Fentanyl Act (S 1141) creates a new, broader definition for "fentanyl-related substances" under the Controlled Substances Act, making many chemical variations subject to Schedule I restrictions without needing individual listing. It establishes streamlined research registration procedures for scientists studying these substances, allowing single registrations for multi-site research within institutions and creating expedited processes for new research applications. The bill also includes provisions to allow ongoing research on substances newly added to Schedule I, with specific timelines for researchers to transition to full registration. These changes aim to balance strict controls on fentanyl-related substances with the need for medical research on these compounds.
