Pre-employment and ongoing substance screenings, encompassing both illicit drugs and alcohol, are common practices in many industries. For example, transportation, healthcare, and manufacturing sectors often implement these procedures to maintain safety standards and ensure a productive workforce. These screenings typically involve urine, blood, or breath tests, and are conducted by certified laboratories following established protocols.
Such testing contributes to safer work environments by mitigating risks associated with substance impairment. It can also deter substance abuse, promote employee well-being, and protect company reputation. Historically, the use of substance testing in the workplace emerged alongside growing awareness of the impact of substance use on safety and productivity. Legislation and court rulings have shaped current practices, establishing guidelines for legality and employee rights.
