It depends on what information is needed. Hair tests can give a longer history of drug use than urine or blood. Urine tests can detect certain substances from anywhere to several hours or up to a month after use. Blood tests show what substances are currently active in the bloodstream and in what amount.
Also, there are many types of urine drug tests, some more accurate than others. Most of the urine tests that are used for employment and for law enforcement (including court officer testing) have a a larger margin for false negative and false positive than is common knowledge.
