Understanding Illegal Drug Use: How Long Does Cocaine Stay In Your System?

How long does cocaine stay in your system? The answer to that question depends on what type of cocaine you use and the type of test being conducted to identify signs of cocaine use. Therefore, it may be difficult to test positive for the substance even if you’re a heavy user. However, the nature of cocaine may also make it possible to test positive for the substance weeks after use.

How Long Does Cocaine Stay In Your System?

The cocaine itself will metabolize through the bloodstream within 48 hours after use. Therefore, a blood test may come up negative if it isn’t conducted soon after you’ve used the substance. However, there could be traces of benzoylecgonine in the blood for several hours or days if you’re a chronic user, as the substance will accumulate over time. Benzoylecgonine is a metabolite that forms after cocaine enters the body.

A urine test may be able to detect this substance or the metabolite up to four days after cocaine has been used. Chronic users may test positive up to a week or more after the last use. In some cases, positive urine tests could occur up to three weeks after you’ve used cocaine. However, the concentration of cocaine in the body tends to go down after you use the restroom. Generally, a positive test is confirmed only if there’s 300 g/mL or more in the blood or urine.

How Long Does Cocaine Stay In Your System With Follicle Testing?

Like most drug tests involving hair follicles, you may test positive up to 90 days after the substance has been ingested. Unlike other substances, cocaine residue may be found at the root of the hair. This means that a positive test could occur at any time until the hair either falls out or is cut off. Therefore, it’s possible that a positive test could occur months after you stop using if you’ve not gotten a haircut or the hair is still on your head.

How Long Can Cocaine Stay In Saliva or Other Bodily Fluids?

As cocaine tends to metabolize quickly, it generally won’t be found if saliva testing is conducted more than 12 hours or so after last using the drug. In some cases, cocaine has been known to stick around in saliva for as long as 19 hours, depending on the concentration of cocaine and the concentration of cocaine being tested. If other fluids such as sweat are tested, the substance could be detected up to 24 hours after it has entered your body. Typically, the odds of detection are highest in sweat four hours after cocaine has been ingested.
