Relating to designating certain substances as Schedule IV controlled substances under the Texas Controlled Substances Act.

HB 151 designates carisoprodol (a muscle relaxant), mifepristone, and misoprostol as Schedule IV controlled substances under Texas law. This change would subject these substances to stricter regulation, including prescription requirements and penalties for unauthorized possession or distribution. The bill takes effect January 1, 2026, applying only to offenses committed on or after that date, with prior offenses governed by existing law. It directly affects individuals and providers handling these substances in Texas, requiring compliance with Schedule IV controls.
