How long after use can Cocaine be detected by a urine test?
Q: I have accepted employment and will soon undergo drug testing and am concerned about the length of time cocaine may be detected. Information I have found says 2-4 days since last use, but I also found something saying the half life of Benzoyl-ecgonine in urine is LONGER. What does this mean? What's the bottom line on detecting cocaine in blood or urine in pre-employment screening?


A: Depending on your body size and metabolic rate, cocaine should not take more than a few days to clear your system for a urinalysis. The standard safety margin is 3-5 days for infrequent use. If you have been a regular or heavy user it may take slightly longer. Refer to the Drug Testing Vault for more information.
