"Elimination of cocaine is predominantly controlled by its biotranformation. Very low concentrations of cocaine may be detected in urine during the initial several hours, but benzoylegonine persists in urine at detectable concentrations for 48 hrs."
---Onsite Drug Testing

Long term habitual users may have traces of cocaine remain in their system for longer than the standard 3 days. (See Reference)

Test Information
The standard cocaine tests are a one step rapid, qualitative immunoassay for the detection of beonzoylecgonine, a hydrolytic degradation product, in urine. The cutoff concentration for the immunoassay test is 300 ng/ml, as recommended by the Substance Abuse and Mental Health Services Administration (SAMHSA) (NIDA). The cutoff for GC-MS is 150 ng/ml.

Cocaine is one of the "NIDA 5". The five drugs tested for in the standard NIDA approved drug test.

Illinois State Appellate Court for the Circuit Court of Cook County found that drinking coca tea without knowledge that it contains cocaine cannot be grounds for being fired as a police officer under "zero-tolerance drug testing" policies. See Garrido v Cook County Sheriff's Merit Board, June 9 2004.
