DOT drug tests require laboratory testing for the following five classes of drugs: 1  Marijuana. 2  Cocaine. 3  Opiates - opium and codeine derivatives.  Amphetamines and 1  methamphetamines. Phencyclidine  â PCP.
A federal mandate requires that drug tests screen for all five of these types of drugs. Time Frame Hair drug tests can detect drugs that have been in the system for 90 days, or three months.

The hair test can also detect drugs that have been in the system for a much longer period of time than a urine test.
