The procedure involves analyzing a biological specimen to detect the presence of specific substances, or their metabolites, that indicate drug use. This assessment is often a component of pre-employment screening processes. For example, a prospective employee might be required to provide a urine sample which is then tested for substances such as marijuana, cocaine, and opioids.
The practice serves to maintain workplace safety and mitigate potential risks associated with impaired employees. Historically, such evaluations have become increasingly common across various industries as employers strive to foster a secure and productive environment. A drug-free workplace is often seen as essential for reducing accidents, improving employee morale, and minimizing liability.
