How Long Does Cocaine Stay in Your System?

In this blog post, we attempt to answer the common question “How Long Does Cocaine Stay in Your System?”.  This is a common question we get asked at our drug rehab clinic. By using the word “system”, we define this as meaning your blood, your urine and your hair. If you have asked this question, it is highly likely you have consumed cocaine recently and you are perhaps worried you may become subject to drug testing. If this is the case, we feel for you. By the time you have read this article, you will roughly know how long cocaine stays in your system.

So how long?

If you are an occasional cocaine user, cocaine typically remains in your body for around 2-4 days following consumption.  Drug tests generally will not detect cocaine in your urine following this amount of time. If you are a long-term cocaine user, then it’s difficult to say how long cocaine will remain in your system. The drug could, for instance, be detectable in your urine after 7+ days of non-use.

The amount of time cocaine remains in your system is also influenced by how you consume the drug. Cocaine may be consumed orally, by inhalation, by snorting (intranasal) and intravenously (injecting).  When cocaine is consumed intranasal, the drug is then absorbed into the blood via the nasal tissue.  When you inject cocaine, the drug is obviously allowed to directly enter the bloodstream. Injecting cocaine causes the user to experience heightened intensity when compared to snorting cocaine nasally.

If you smoke cocaine, the drug is vaporised. Vaporised cocaine enters the blood through the lungs. Smoking cocaine is comparable to injecting in terms of the amount of time it takes to enter the bloodstream. This means snorting cocaine is perhaps the most inefficient way of consuming cocaine in terms of the amount of time it takes to enter the bloodstream.

Why do people use cocaine?

The vast majority of people choose to consume cocaine for social and recreational reasons. Cocaine keeps people alert and helps to fight off fatigue. This is particularly beneficial for people who want to continue to drink alcohol into the small hours of the night. Cocaine is also a favourite amongst people who attend sex parties since the drug helps to improve their sexual performance.

Cocaine also allows the user to experience a sense of euphoria. This allows the user to forget all about his or her problems. This is why cocaine is highly addictive from a psychological standpoint.  Cocaine was originally consumed as a tea to relieve fatigue similar to modern day coffee. Also, people chewed cocaine as a means of relieving fatigue.

The half-life of cocaine

Cocaine is classed as a stimulant. Cocaine is manufactured from leaves of coca plants. Scientifically, cocaine’s ‘half-life’ is around 0.2 to 0.8 hours. This means the amount of cocaine in the bloodstream will half during this period until it is finally filtered out altogether.

Benzoylecgonine is the central metabolite (a byproduct) of cocaine. Benzoylecgonine is formed in the liver when cocaine is metabolised. Benzoylecgonine is one of the substances that’s detected when you undergo a drug test. Benzoylecgonine has a half-life of 6 hours.

Another metabolite of cocaine is formed when cocaine is mixed with alcohol. This metabolite is known as Cocaethylene. Cocaethylene has a longer half-life than benzoylecgonine and cocaethylene is also much more toxic.

How cocaine is consumed

The manner in which cocaine is consumed also impacts the amount of time cocaine remains in your system. If you consume 140 mg of cocaine by snorting the drug, the amount of cocaine in your system will peak at 30 minutes and benzoylecgonine will peak at around 3 hours following consumption. In contrast, if you consume cocaine orally, the same amount of the drug will peak at around one hour.  If you consume cocaine intravenously, the amount of cocaine in your blood will peak at 5 minutes after consumption.

Should I worry about cocaine drug testing?

The answer to this question is a categorical YES! If your employer carries out drug testing, it’s never worth the risk of getting caught. Furthermore, cocaine kills hundreds of thousands of people each year, so it’s never worth the risk because you could ultimately end up losing something much more valuable than just your job.

When cocaine is metabolised, it is transformed into a number of by-products that are entirely inactive and harmless. The vast majority of cocaine is metabolised within as little as 4 hours after use. However, the remaining byproducts may remain in your body for days. In some instances, these byproducts may be detected many months after cocaine was last consumed.

How long does cocaine remain in my hair?

Cocaine traces remain in the hair for around three months after consumption. In some instances, cocaine may remain in the hair until the hair falls out or is cut. Some drug tests require you to submit a hair sample for this reason.

How long does cocaine remain in my urine?

Unfortunately, it’s hard to pin down an exact time frame for how long cocaine remains in the urine. In some instances, cocaine’s by-products such as benzoylecgonine have been detectable in urine when cocaine was consumed several weeks ago. For this reason, urine tests are popular amongst companies offering drug test facilities to employers.  If you have consumed small doses of cocaine, expect the drug’s byproducts to remain in your urine for around 2-4 days. If you are a heavy user, the drug may remain in your urine for several weeks following a period of abstinence.

How long does cocaine remain in my saliva?

Cocaine is eliminated from saliva after around 2 hours after use. For this reason, saliva testing for cocaine use is generally not commonly used for drug testing.
