Drug testing in the workplace is a practice employers often use to promote safety, productivity, and compliance with legal or regulatory standards. It is particularly common in industries where safety is critical, such as transportation, construction, and healthcare. Employers may implement pre-employment, random, or post-incident drug testing as part of their policies to ensure a drug-free workplace. However, it is essential to balance these practices with employee rights and privacy considerations, as well as compliance with federal, state, and local laws. A clear, consistently applied drug-testing policy that aligns with legal requirements and includes resources for employee education and support can help foster a safe and effective work environment.
