Substance screening prior to hiring often includes testing for both illicit drugs and alcohol. This process typically involves analyzing a urine, blood, or breath sample to detect the presence of alcohol or specific drug metabolites. For example, a urine test might screen for amphetamines, cocaine, marijuana, opiates, and phencyclidine, while a breathalyzer would measure blood alcohol content (BAC).
These screenings aim to ensure a safe and productive work environment by identifying potential safety risks associated with substance use. Historically, concerns about workplace accidents and productivity losses led to the adoption of these practices. A drug and alcohol-free workplace can minimize accidents, especially in safety-sensitive positions, and potentially reduce absenteeism and improve overall productivity. This benefits both the employer and employees by fostering a healthier and more focused working atmosphere.
