At Zoom Testing we are often asked about detection times for cocaine. A detection period is the amount of time after consuming a drug that a particular testing method can still show a positive result. So, for how long does cocaine stay in your system?
Benzoylecgonine is the main metabolite of cocaine. A urine drug test for cocaine will actually screen for that metabolite. Many factors determine how quickly it gets cleared from the body.
How Long Does Cocaine Stay In Your System?
- The amount of drug taken.
- How frequently the drug is being taken
- Individual body weight and height.
- Overall rate of metabolism, which depends on an individual’s levels of activity and health status.
How long does it take for cocaine (or crack) to clear out of urine?
Detection times for cocaine in urine are significantly greater than detection times in saliva. When urine is being screened for the presence of cocaine, it is actually benzoylecgonine, a metabolite of cocaine, that is being measured. The widely accepted time period for benzoylecgonine to be cleared from the urine is three to five days. However, the time period for heavy users of cocaine can be longer, with one study suggesting that benzoylecgonine can be detected in chronic cocaine users for 10-14 days.
How long can cocaine (or crack) be detected in saliva?
Typically cocaine can be detected by a saliva drug test over a period of 24 to 48 hours after the last use. Once again, this time may vary according to each person’s metabolism, as well as the quantity and quality of the drug that was consumed.
