S. 331: HALT Fentanyl Act

119th Congress · Sponsored from Louisiana · Became law

What this bill does

Halt All Lethal Trafficking of Fentanyl Act or the HALT Fentanyl ActThis act permanently places fentanyl-related substances as a class into schedule I of the Controlled Substances Act. A schedule I controlled substance is a drug, substance, or chemical that has a high potential for abuse; has no currently accepted medical value; and is subject to regulatory controls and administrative, civil, and criminal penalties under the Controlled Substances Act.Under the act, offenses involving fentanyl-related substances are triggered by the same quantity thresholds and subject to the same penalties as offenses involving fentanyl analogues (e.g., offenses involving 100 grams or more trigger a 10-year mandatory minimum prison term).Additionally, the act establishes a new, alternative registration process for certain schedule I research.The act also makes several other changes to registration requirements for conducting research with controlled substances, includingpermitting a single registration for related research sites in certain circumstances,waiving the requirement for a new inspection in certain situations, andallowing a registered researcher to perform certain manufacturing activities with small quantities of a substance without obtaining a manufacturing registration.Finally, the act expresses the sense that Congress agrees with the interpretation of the Controlled Substances Act in United States v. McCray, a 2018 case decided by the U.S. District Court for the Western District of New York. In that case, the court held that butyryl fentanyl, a controlled substance, can be considered an analogue of fentanyl even though, under the Controlled Substances Act, the term controlled substance analogue specifically excludes a controlled substance.
