Workplace drug impairment cases often hinge on the relationship between observed on-the-job behavior and the results of drug testing that may be delayed, limited in scope, or legally restricted. While employers face significant safety and liability concerns, evolving laws and regulations increasingly constrain how and when employees may be tested for impairing substances.
As a result, drug test results frequently fail to capture real-time impairment, particularly in cases involving novel psychoactive substances, prescription medications, or off-duty use. This disconnect creates legal risk on both sides—ranging from wrongful termination and discrimination claims to overlooked impairment that contributes to workplace incidents.
