How Long Does Cocaine Stay in Your Urine?

Cocaine dependence can cause drug withdrawal if you’ve gone a certain amount of time without taking more cocaine. Effects of cocaine, such as increased heart rate and euphoria, are short-lived, usually lasting anywhere from a few minutes to an hour at most. There are several scenarios that could call for a person to get tested for cocaine use. how long does cocaine stay in your system Cocaine, also known as coke or blow, is a powerful stimulant drug that can cause a rush of euphoria, as well as other physical and psychological side effects. If you believe you have a false positive test, ask for a second test to verify the result. These tests are easy to administer, more secure, and harder to “cheat” than urine tests.

And the more manageable the detoxification process is, the higher the likelihood will be for staying off of cocaine for good. It does take almost one week for signs of coke use to show up in the hair. This is because drugs are not stored in the hair until completely broken down. However, the more comprehensive method also comes at a greater cost to employers.

Here’s a quick overview to help break down the various onset times and durations of the different methods of abuse.

Whether you’re snorting, smoking, injecting, or taking cocaine orally. Drug screens can be ordered as a precaution, or to follow up on suspected substance use. The criminal justice and legal systems also use drug testing during the course of some criminal investigations, motor vehicle accidents, and court cases. Cocaine may be eliminated more slowly when combined with alcohol. The combination produces the metabolite cocaethylene, which not only eliminates more slowly but enhances the cardiotoxic effects of cocaine and alcohol.

  • Cocaine is a fast-acting central nervous system stimulant that can cause a short-term rush and euphoric high that lasts from a few minutes to less than an hour.

  • Naturally, this can make it hard to figure out how long cannabis stays in your system.


Because hair and blood samples are somewhat costly, they are rarely administered by employers. Of course, the window of detection depends largely on the general health of the patient’s main filtration organs (the liver and the kidneys) as well as their past cocaine abuse habits. Chronic users will tend to accumulate deposits of the drugs within their actual tissues. Cocaine stays in the bloodstream for a much shorter period compared to the urine. In fact, most traces of the drug itself will be undetectable after just an hour and a half. The most easily detectable metabolite of cocaine is called benzoylecgonine.

And in most cases, a drug test of any kind (urine, blood, hair, saliva) will be designed to detect this metabolite in particular. Saliva tests usually detect cocaine consumption within 24 hours to 2 days after consumption. This will, of course, depend on the volume consumed and individual metabolism rate. As such, most people testing positive on a blood test did so within 24 hours of their last use.

  • If they’ve only done coke one time, the drug probably hasn’t had time to accumulate in the tissues yet.
  • After all, it’s impossible to know exactly how long weed will show up in your system.
  • Cocaine—also known as crack, coke, and blow—is an illegal stimulant drug that takes the form of a white, crystal powder.
  • And because both of these metabolites are only present in the body after an individual has been abusing cocaine, spotting these is a solid indication that they’ve been using recently.
  • The length of time cocaine stays in urine depends on several factors, including the amount of cocaine used, the frequency of use, and the individual’s metabolism.

Cocaine Drug Tests & Benzoylecgonine

As the liver works hard to rid your system of coke, it floods your sweat glands with the chemicals and toxins that have built up over the course of an addiction. And that can mean that cocaine and its metabolites can end up remaining detectable in their bloodstream for far longer compared to a casual user. If you are being tested for cocaine, crack or other substances in your system, the lab may be looking for cocaethylene in addition to benzoylecgonine and cocaine itself. This is because the two substances, when combined, actually create a new chemical. Unlike other metabolites of cocaine like benzoylecgonine, cocaethylene is an active metabolite, meaning it has a direct effect on the body and its organs.

Positive results indicate levels that are above the cutoff, which may trigger the need for confirmatory testing. Immunoassay tests use antibodies that are designed to bond specifically with cocaine’s metabolites. When a sample is introduced to the test, the color will change (or some other signal is given) if the drug’s metabolites are present. Confirmatory tests use gas chromatography-mass spectrometry (GC-MS) or liquid chromatography-mass spectrometry (LC-MS). Cocaine is a powerful stimulant drug that is derived from the leaves of the coca plant, which is native to South America. It has been used for centuries in various forms, such as chewing the leaves or brewing them into tea, for their stimulant effects.

Cocaine Detection in Urine

However, some laboratories with less accurate technology available sometimes obtain false positives. Certain medicines produce metabolites with a somewhat similar structure to benzoylecgonine while some other substances may cause a false positive. Benzoylecgonine happens to have a much longer half-life than cocaine; it can reach six hours, sometimes more. So it takes much longer to get eliminated from the body than cocaine.
