72 hours: Cocaine is a relatively short-acting drug and does not tend to accumulate in the body. The amount used has little effect on how long it stays detectable in urine. The method of testing (dipstick tests like RIA and eia) vs. More complex methods (thin layer or gas chromatography, mass spectrography) also can make a little bit of difference. But in general its about 3 days. If you need help, get it.
