How Long Does Cocaine Stay in Your System? What to Expect

These tests often look for unchanged cocaine, crack, and benzoylecgonine, cocaine and crack’s most prominent metabolite. Metabolites are the parts of drugs that stay in the body as the substance breaks down or metabolizes. Crack and cocaine share many of the same metabolites because crack is a derivative of cocaine. However, crack cocaine can stay in your system for a much longer length of time, or anywhere between 3 to 7.5 hours after last use. Cocaine is typically detectable in urine for up to three days after use.

This means that a person will enter withdrawal shortly after stopping cocaine and that a blood, saliva, or urine test will only show the presence of cocaine for a few days. Because cocaine can linger in the hair longer, a hair test may be positive for months or years. However, in general, Cocaine will be detectable in your system for up to 72 hours after last use.

Factors That Can Affect Cocaine Detection Times

Cocaine is a stimulant drug, which means that it increases activity in the central nervous system. This can make a person feel more energetic and may also cause anxiety or aggression. Cocaine metabolism begins when a chemical in the blood plasma called plasma butyrylcholinesterase (BChE) breaks down cocaine into a chemical called ecgonine methyl ester (EME).

If a more sensitive and reliable test is required, lab tests are administered. Regardless, positive results should always be sent to a lab to confirm accuracy. They mix together in the body to produce a toxic chemical called cocaethylene. This affects the cardiovascular system and increases the risk of overdose.

How long do the effects take to kick in?

It should not be used to replace the suggestions of your personal physician or other health care professionals. Getting the right help for cocaine addiction is important because this drug can cause serious harm to a person’s health. No one should have to go through the excruciating detoxification process on their own.

In some studies, BE is detectable for up to 106 hours or 4.5 days after the last ingestion of cocaine. Most commercial urine cocaine tests have a detection window of 3–5 days. Cocaine is a stimulant that makes a person feel euphoric and gives them energy. Because it’s so short-acting, people will often use it over and over in a short period.

Risks of mixing cocaine with other substances

A hair analysis is useful because there is a wider window of detection with a strand of a person’s hair. 72 hours after a person uses cocaine for the first time it is undetectable in a urine test. Compared to a urine test, a hair test can detect cocaine over the course of days or even months. It is 6-10 times or 85 percent more effective in identifying abused drugs than a urine analysis. This guarantees that a person who uses the substance cannot trick the test by simply abstaining from the drug for a few days. A few other advantages are it is a non-intrusive test, a person can’t tamper with the test, and the test can be repeated so there is greater accuracy.

All hair testing can detect substances for the same length of time, about 90 days. The reason is that the testing window is based on how quickly the hair usually grows. Substances are deposited in the hair after use and can be detected for up to three months. This type of testing is expensive and hard to perform, so it is less common.

Is it safe to use with alcohol?

Approximately 30-50% of cocaine is metabolized by hepatic esterases and plasma pseudocholinesterase (both enzymes are produced in the liver). These enzymes break cocaine down into a water-soluble metabolite. Another 30-40% is broken down into benzoylecgonine, another major metabolite, which has been known to induce seizures and can be detected for hours to days following the last use. These tests look for the presence of both cocaine and its metabolites. These metabolites are the chemicals that the body makes to process cocaine. Rapid screening tests can provide results in minutes, so they are generally used in clinics or offices.

  • If a person uses cocaine repeatedly and at increasingly higher doses, they may start to feel increasingly irritable and restless.
  • Unfortunately, the more serious problems like brain bleeding can go unnoticed by a person using cocaine.
  • The cocaine saliva test is a quick and easy test for cocaine use.

Additionally, both substances are illegal in the United States, and you may face legal, financial, or vocational consequences if you test positive for either of them. However, suppose you have used Cocaine recently and are facing an upcoming drug test. In that case, there are a few things you can do to try to reduce your chances of testing positive. If Cocaine is present in the saliva, the solution will change color.

Bloodborne infections

That’s not to say fetal cocaine exposure isn’t harmful, but it’s hard to identify risks that are specific to cocaine exposure alone. Cocaine does cross into the placenta, meaning it reaches the fetus. When used in the early months of pregnancy, cocaine can increase the chance of miscarriage and placental abruption.

For regular users of moderate doses, benzoylecgonine can take 20 days to fade. Saliva tests can involve either a cheek or tongue swab or a device used to extract saliva from the mouth. Unchanged cocaine or crack, as well as benzoylecgonine, can be found in saliva for up to 2 days after the last dose. Drug tests try to detect various types of substance use, including cocaine use.
