General Statute

Pennsylvania has no law addressing drug testing in private employment.

Unemployment Denial - § 802. Ineligibility for compensation

Workers Comp Discount - 77 P.S. § 431

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 refusal or positive post-accident test after an injury.
