Illinois State Drug Testing Laws

Workplace Drug Testing Issues – Illinois State Laws

Illinois requires employers on State public works projects to maintain a drug-free workplace.

General Statute--This state has no known statutes restricting workplace drug or alcohol testing. A separate law in Illinois exists that mandates and regulates drug testing by public works employers.

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.

State and local law varies greatly; therefore, you are advised to consult experienced legal counsel during the design of your actual substance abuse testing program and with any questions that follow.
