A urine drug test, also known as a urine drug screen or a UDS, is quick and painless. It tests your urine for the presence of certain illegal drugs and prescription medications. The urine drug test usually screens for alcohol, amphetamines, benzodiazepines, marijuana, cocaine, PCP, and opioids (narcotics).
The most common type of drug tests performed is a urinalysis which tests for the presence of marijuana in your urine. Urinalysis tests account for about 75% of drug tests; hair tests and blood tests make up for the other 24 % with about 1% of tests being saliva based.
