Workplace Drug Testing Issues – Minnesota State Laws

These categories do not affect DOT-regulated drug testing. Government employers should always call for potential additional restrictions on employee drug testing.

A written drug-free workplace policy is required in Minnesota. See also Minnesota's Drug and Alcohol Testing Act; AUTHORIZED DRUG AND ALCOHOL TESTING – 181.951

Important to Note: In Minnesota, employers are required to notify employees and applicants in writing of both positive and negative results within three days of receipt of the results from a laboratory.

Intoxication Defense – Denial of Workers Compensation Claim – States vary in their willingness to allow employers to use an injured worker's intoxication against a compensation claim. State laws' intoxication defenses generally fall into one of three rough categories: reasons 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.

Instant or POCT drug testing is prohibited in Minnesota for workplace drug testing, and this would also include breath alcohol testing in non-DOT workplace situations.
