Relating to a study on establishing testing and scientific standards for determining tetrahydrocannabinol intoxication.

HB 198 directs Texas' Department of State Health Services to study scientific methods for testing tetrahydrocannabinol (THC) intoxication, similar to blood alcohol content standards. The study must evaluate existing testing methods, develop a scientifically valid intoxication threshold for legal use, and create legislative recommendations. It specifically aims to support prosecutions under Texas Penal Code Chapter 49 (DUI offenses), civil liability cases, and workplace safety regulations. The department must submit a final report with recommendations by October 1, 2026, to state leadership. This bill creates a study process but does not enact new laws or directly affect residents.
