Medical Marijuana –  Texas Compassionate Use Act (Senate Bill 339) – Texas Occupations Code §169.001

Intoxication Defense – Texas Labor Code 406.032(1)(A).

Intoxication Defense – States vary in their willingness to allow employers to use an injured worker’s intoxication as a defense against a claim for compensation.  State laws’ intoxication defenses generally fall into one of three rough categories: defenses that do not depend on causation; defenses that require some form of proximate causation between intoxication and injury; and defenses that require that intoxication be the sole cause of injury.  Always check with your insurance company and your attorney when you have a positive post-accident test after an injury.
