The half-life of the drug represents the amount of time it takes for levels of the drug to be reduced by half of their original concentration. According to one study, the average half-life of cocaine is about 1.5 hours in blood, 1.2 hours in saliva, and 4.1 hours in urine. how long does cocaine stay in your system But after binges in chronic users, it can be detectable for up to two weeks. Urine testing is the preferred approach for screening coke use if there is no medical emergency. The conversion to other cocaine metabolites detectable in urine is much broader and longer.

  • Cocaine is a powerful and addictive drug that can damage a person’s health and well-being.
  • Whenever in doubt, it is advisable that health care providers (HCPs) contact their laboratory to investigate tampering.

  • We conclude that values above 100 ng/mL are indicative of recent use.

It will be very hard to tell if cocaine is still detectable in your blood or not because there have been cases where it wasn’t detected even after using for a long time. There also have been cases where it was detected easily after using it only once or a few times. The only way to https://ecosoberhouse.com/ know for sure is to test for it yourself using at-home drug testing kits. Urine tests may test for cocaine itself or its metabolite, benzoylecgonine. A urine test can directly test for cocaine for a day or less but will detect cocaine metabolites for a few days — usually 1–2 days.

Does Method of Use Affect How Long Cocaine Stays in Your System?

In a second study, the results of three patients monitored over several weeks are presented in Tables 1, 2, and 3. The patient in Table 1 demonstrated an extended elimination of benzoylecgonine, with detectable levels after 12 days. For all the studies a very sensitive dilute and shoot assay for benzoylecgonine was developed using a Sciex 6500 instrument with a lower limit of quantitation of 5 ng/mL.

  • It’s possible for cocaine to be present in urine, blood, saliva and hair.
  • It is also possible that the study conclusions are confounded by measured or unmeasured variables that may differ between cocaine-positive and cocaine-negative patients.
  • Chromatography generally is reserved for confirmatory or definitive testing when the initial UDM by IA results are unexpected.1 Unlike IA, chromatography can detect the presence of specific drugs and/or metabolites.
  • Therefore, a blood cocaine test is really just a test to measure if someone is currently under the influence of cocaine, not whether they have recently used it.

Cocaine can be detected in the urine for up to four days after use, on average. Going on a cocaine binge, using multiple drugs, or having a slow metabolism can affect detection time. Cocaine is a highly addictive drug that can be detected in urine samples for some time after the effects of the drug have worn off. Although the length of time cocaine stays in the system can vary, urine tests can generally detect cocaine for up to four days after your last use. An essential composite resulting from the breakdown of coke is benzoylecgonine.

How Long Is Cocaine in Urine?

The College may, at its discretion, reassess this position at any time if and when new relevant data emerges. The length of time that cocaine will remain in a person’s system depends on a number of factors. Also, some substances can create a false positive, including coca tea, some cold medications and second-hand smoke from marijuana. If you know you’re clean and test positive, request a secondary test.

Cocaine also elevates temperature, heart rate, blood pressure, and stimulates stress systems throughout the body changing or damaging vital organs and system. Cognitive-behavioral therapy is a treatment for cocaine abusers that can be taken at rehabilitation or separately. It’s common for cocaine users to use the stimulant drug repeatedly in short timeframes to maintain the high. This is known as a binge, which often concludes with an unpleasant crash. How long it hangs around and how long it can be detected by a drug test depends on several factors.

Cocaine

The metabolites created by the metabolization process travel to the urine, hair, saliva, and bloodstream, eventually leaving the body. A blood cocaine test looks for cocaine or its metabolite in the blood plasma. This means that false positives or negatives for cocaine use are very rare.
