Drug and Alcohol Testing in the Workplace Act (privacy safeguards)

Allows workplace drug, alcohol, and cannabis testing only under a written policy and only in listed situations (post-offer applicant testing, annual physicals with notice, random testing for safety-sensitive jobs, reasonable suspicion, and treatment follow-up). Laboratories may tell employers only whether substances were present, and test results are private and confidential, not usable in criminal cases against the employee.
