What is a drug test and why is it required?

A drug test is a technical analysis of a biological specimen — such as urine, hair, oral fluid (saliva), or blood — to determine the presence or absence of specified drugs or their metabolites. Drug testing is commonly required by employers for pre-employment screening, random workplace testing, post-accident investigations, reasonable suspicion, and return-to-duty situations. It is also used in legal, medical, and rehabilitation settings.
