H.B. No. 1339 amends the Texas Controlled Substances Act by designating certain substances as Schedule IV controlled substances. The bill specifically adds carisoprodol, mifepristone, and misoprostol to the list of Schedule IV substances, replacing the previous designation of only carisoprodol. This change aims to regulate these substances more strictly under Texas law.

The bill stipulates that the changes will only apply to offenses committed on or after the effective date of September 1, 2025. Offenses that occurred before this date will be governed by the law in effect at the time of the offense, ensuring that individuals are not retroactively penalized under the new regulations.
