SIMSA Act of 2024

The SIMSA Act of 2024 creates a new Schedule A for controlled substances in the U.S. Controlled Substances Act, targeting imported substances with chemical structures similar to existing controlled substances that produce comparable effects on the central nervous system. The Attorney General can temporarily place substances in Schedule A for up to 5 years (with possible 180-day extensions), requiring a review for permanent scheduling within 3 years. The bill increases penalties for violations involving Schedule A substances (up to 20 years in prison for first offenses, 30 years for repeat offenses) and requires specific labeling using IUPAC nomenclature. It also includes provisions for research on substances newly added to Schedule A and allows for sentencing review if such substances are later descheduled.
