TX HB5412

Expands the definition of "intoxication" under the Texas Workers' Compensation Act by removing the requirement that substance introduction be "voluntary" and changing "resulting from" to "by reason of" for impaired mental or physical faculties

Updates terminology from "abusable glue or aerosol paint" to "abusable volatile chemical" to align with current Health and Safety Code definitions

Creates a rebuttable presumption of intoxication when autopsy specimens (blood, urine, or other bodily fluids) show the presence of alcohol, controlled substances, dangerous drugs, or other regulated substances

Requires that the presumption of intoxication can only be rebutted by "credible and objective evidence" that the person was not intoxicated

Applies only to workers' compensation claims for injuries occurring on or after September 1, 2025
