This process facilitates unscheduled substance use verification, triggered by specific events or reasonable suspicion. For example, an employer might request immediate screening following a workplace accident or observable behavioral changes in an employee.
Such immediate evaluation offers a significant advantage in maintaining safety-sensitive environments and upholding company policies. Its implementation can deter substance abuse, provide evidence for disciplinary actions, and contribute to a safer, more productive work setting. Its utility has grown alongside increasing societal awareness of workplace safety and substance abuse prevention.
