Workplace Drug Testing Laws in Montana

Montana's workplace drug testing laws are outlined in the Montana Workforce Drug and Alcohol Testing Act (Mont. Code Ann. §§ 39-2-205 to 39-2-211). Drug testing is required for employees in hazardous or high-risk jobs, but employers in non-hazardous industries can also create drug testing policies. Employers with a drug testing program must follow their written policy and ensure it complies with state law.

Although Montana has legalized cannabis for both medical and recreational use, the law does not require employers to allow marijuana use or possession in the workplace. Employers can also take disciplinary action against employees who violate workplace drug policies or are impaired at work.
