Relating to the testing of evidence for controlled substances by the Department of Public Safety.

This bill requires the Texas Department of Public Safety (DPS) to test all evidence containing suspected controlled substances (drugs) in criminal cases using approved laboratory methods. It applies only to evidence submitted to DPS on or after September 1, 2025, by state attorneys prosecuting criminal cases. DPS must complete testing within 180 days; if not, they must return the evidence and reimburse the state for independent testing. This affects criminal drug cases by ensuring timely, standardized evidence processing.
