Drug Testing in Michigan: State Laws, Marijuana Laws, and Employer Compliance
When workplace safety, legal compliance, and dependable drug screening matter, Michigan employers trust National Testing Services (NTS) as the nation’s leading provider of professional drug and alcohol testing services.

While marijuana legalization has expanded personal use rights, employers still maintain significant authority to enforce workplace drug policies. National Testing Services helps Michigan employers, legal professionals, and individuals stay compliant with accurate, confidential, and legally defensible drug testing solutions.
