General Statute--Mississippi has a voluntary testing law that regulates alcohol and drug testing of applicants and employees, requires employers that test to have a written policy, and specifies testing procedures. MS Code Sec. 71-7-1 et seq. - CHAPTER 53 DRUG AND ALCOHOL TESTING REGULATIONS

Mississippi Code for Drug Testing – MS Code § 71-7-1

Workers Comp Discount – §71-3-207

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.
