Relating to the scheduling of certain controlled substances in response to certain actions by the United States Food and Drug Administration with respect to those substances.

HB 4813 requires Texas to automatically align its controlled substance schedules with federal changes made by the U.S. Food and Drug Administration (FDA) for certain drugs. Specifically, if a substance in Texas' Schedule I is FDA-approved for medical use (under Section 505 of the Federal Food, Drug, and Cosmetic Act), gets rescheduled federally to a lower category, or is deleted from federal schedules, Texas must delete or reschedule it "as soon as practicable" after notice. This applies only to substances affected by federal actions on or after the bill's effective date (September 1, 2025). The bill ensures Texas law follows federal medical approvals without requiring new state hearings for these specific changes, directly affecting the Texas Health and Safety Code commissioner and entities handling these substances.
