Relating to the creation of a grant program to assist local law enforcement agencies in testing certain substances suspected of containing delta-9 tetrahydrocannabinol.

SB 2451 creates a grant program for Texas local law enforcement agencies to test substances suspected of containing THC (delta-9 tetrahydrocannabinol) above 0.3% concentration. Agencies must have qualified peace officers and a written agreement with state attorneys to evaluate evidence for potential prosecution before receiving funds. Grants can only pay third-party labs to conduct THC testing, not cover other costs. Recipients must report details like the number of tests, substances tested, costs, and case outcomes to the criminal justice division. The program requires annual reporting to the state and includes data aggregation by region in the division's biennial report.
