SIMSA Act of 2025

This bill creates a new drug category, called Schedule A, for imported substances that are chemically similar to existing controlled drugs and have similar or stronger effects on the brain but are not yet listed in any schedule. The Attorney General could add a substance to Schedule A by temporary order lasting up to 5 years, and could make the listing permanent after 3 years unless federal health officials find the substance does not have enough potential for abuse. Importing Schedule A substances illegally would carry prison terms of up to 20 years, or up to life if death or serious injury results, and products would need labels using standard chemical names. The bill also sets registration rules for importers, exporters, and researchers, and lets people sentenced under it ask for a sentence reduction if a substance is later removed from Schedule A or moved to a lower-penalty schedule.
