Can an employer in Maryland discipline a medical marijuana patient who tests positive for marijuana? – Yes, if the requirements of state drug testing law are met.

Workers’ Compensation intoxication defense to a claim exists. However there is a presumption that intoxication or drugs did not cause the injury.

Maryland Occupational Safety and Health regulations requires employers with safety-sensitive employees to undergo mandatory drug testing that must meet DOT and Maryland drug testing regulations. The following positions are deemed safety-sensitive: crane operators, signal persons, riggers, and crane operator trainees.

Intoxication Defense – Denial of Workers Compensation Claim - 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.
