Cocaine generally stays in your system for about 2-4 days. In fact, this is the detection window for urine for most casual users. However, chronic or heavy cocaine users may have a much longer detection window.

If you want to learn more about cocaine drug testing and your chances to pass a urine, blood, hair, or saliva drug test, continue reading. Main cocaine uses, detection time frames and other aspect of cocaine use here. And if you still have questions about cocaine in your system, you are more than welcome to ask them in the comments section at the end.

How do you take cocaine?

The principal routes of cocaine administration are oral, intranasal, intravenous, and inhalation. Snorting cocaine occurs when the cocaine powder is inhaled through the nose. There, cocaine is absorbed through the nasal tissue to the bloodstream.

Injecting cocaine, or IV cocaine use, releases the drug directly into the bloodstream and heightens the intensity of its effects. Smoking involves inhaling the cocaine vapor or smoke into the lungs. The absorption after smoking cocaine is as fast as by injection.

Main cocaine uses

Cocaine is used mainly for recreational purposes to increase alertness, relieve fatigue, feel stronger and more decisive. Often, cocaine is abused for its intense euphoric effects.  Rarely or seldom is cocaine used as a topical local anesthetic for ear, nose and throat surgery. Traditionally, the coca leaves are chewed or brewed into a tea for refreshment and to relieve fatigue.

Peak levels and half life of cocaine

Cocaine is a powerfully addictive stimulant drug made from the leaves of the coca plant.Cocaine has a short half-life of about 0.8 to 0.2 hours. The half-life of benzoylecgonine, the main cocaine metabolite though is 6 hours.

However, the most important factor for cocaine performance in the body is the route of administration. For example, snorting 160 mg of cocaine results in peak levels at 30 minutes; the peak of benzoylecgonine, is around 3 hours. After oral administration of 140 mg cocaine, peak levels occur in plasma concentrations at 1 hour. And while a single dose of 32 mg IV injected cocaine produces peak plasma concentration within 5 minutes, smoking reaches the peak at 45 minutes.

Cocaine drug testing: How long does cocaine stay in the body?

Cocaine is extensively metabolized to a variety of compounds which are centrally inactive. Most of it metabolizes within 4 hours. But cocaine is still detectable on most drug tests up to a week later and can be “visible” for up to three months in other specific kinds of drug testing.

How long does cocaine stay in blood?

Small part of a cocaine dose may stay in the system and be detected in blood for 48 hours after use. Many users may develop cocaine tolerance, and the changes in cocaine concentrations in storage are also crucial for blood testing. Unlike other drugs, cocaine has a large overlap between toxic, lethal and therapeutic concentrations. There are cases when no cocaine presence in the blood was measured, even after prolonged use.

How long does cocaine stay in hair?

As with other drugs, cocaine concentrations in hair are visible for at least 90 days after dosing. However, cocaine does not leave its marks at the root of the hair, but to specific areas. That means that it is there until the hair falls out or is cut off.

How long does cocaine stay in urine?

As with other drugs, there is no exact window of detection for cocaine in urine. Cocaine metabolites may be excreted in the urine for up to several weeks after use.

Very low concentrations may be detected during the initial few hours, however, benzoylecgonine persists in urine at detectable concentrations from 2-4 days.  Chronic, heavy use of cocaine can result in detectable amounts for up to 10 days following a binge use.

How long does cocaine stay in saliva or sweat?

Saliva elimination of cocaine has a half-life of 2 hours, while some cases have reported cocaine concentrations in the saliva even after 19 hours. Generally. the peak level of cocaine concentrations in sweat is at 4.5 to 24 hours.

Cocaine and addiction

People often underestimate how cocaine can be addictive. Defined as a desire for more of the drug despite the negative consequences, cocaine addiction happens very often to drug users, including all routes of administration.

  46. I have a friend on probation who is randomly being tested for the presence of cocaine in his urine in order to succesfully complete his probation. He has tested 2 or three times and all were positive, however, the program directors were aware that he was a long term heavy user and it wasn’t abnormal to have a few more positive tests than the average recreational user. He stopped using cocaine 60 days ago today (6/3/2018) and tested himself on the last day of May and still showed positive for cocaine. How is this possible. He does take prescription medication which includes weakened kidney function as a side effect and I read that a situation like that could definately influence the time to test clean. Is this even possible? How can abstaining from cocaine for 2 months still show positive on a urine test. Help! He has explained the situation to his probation officer, but he’s going to have to have some kind of justification for this or it will sound like the standard b.s. that they are fed all day from people. Any help would be appreciated!

How long will this take to leave my system? There is a possibility that I will have to take a drug test in 36hrs from now. It will probably be a saliva drug screen. However, out may be a urine test. So, how long do I need to pass eithet of these tests? Our any I just screwed?

  57. How would you define or quantify Chronic, heavy use of Cocaine? for instance.. if a person used about 3 times per week for a month, would that be considered heavy use or somewhere in between? Also, you say that metabolites can be excreted in the urine for up to several weeks, but that heavy, chronic users could be positive for up to 10 days. are those metabolites detectable creating a positive test result for several weeks after use? Or would 10 days be about the maximum window? Lastly, are there any other factors besides frequency and amount of use such as bad liver or kidneys, or any other possible outside factors that would change the expected window of a positive result?

What is considered the amount for heavy usage in grams if you will. For a 5’2 145 pound person, how long would it take.

  104. The key to getting it out of your system is to start by drinking water early. Like as soon as you wake up the next day. Dont over do it. Just make sure are pissing quite frequently. Water is your best weapon above all else. You should have it cleared for a urine screen in 72 hours whether you consumed alcohol with it or not.

  105. How long will the metobolites of cocaine stay in your urine if you used on the second of june and you have a test on July 12th?

  107. I last used cocaine about a month ago. Prior to that it has been years. However, if I have to take a hair test it seems as though I will not pass. However, because you mentioned that cocaine resides in the shaft of the hair and not the actual folicle then it would seem that if I shaved my entire body from head to toe then the new hair would not show signs of cocaine use correct? Thanks in advance for your response.

    1. Hey Ayani. Not to give you any false hope, but if it was a small dose and you only did it that one time, you just might have a chance at not testing positive. It all depends on the sensitivity of the hair follicle test and the amount you used.

  210. Last year I was recreationally using cocaine. I started to take college classes and wasn’t working anymore. My job was doing regular urine test so I never took a chance with excess drug use. After resigning though I started to use ore than before. Before that, use was sporadic throughout my years. Maybe once a year I would do a couple of lines since the age of about 35 I am now 47. I have not used any type of street drugs since Dec of 2015. Due to the fact the field of study I am going in to, they required a hair follicle. I did a hair follicle on Aug of 2016 and cocaine was detected in my hair. I was so sure that they would only go back 3 months and I did not understand how this could be still in my system. This is very devastating because I worked so hard to stay clean for 8 months I will continue to be clean, but how long will it take for my system to be clean for hair follicle?

  264. Hi. Thank you for this detailed article, it was very helpful. I’ll be very specific in my question, so that you can answer more specifically. I used to do cocaine regularly, but have not used it in 5 years. 3 weeks ago, I got a hold of some coke. Over the past 3 weeks, I have been snorting small amounts (a dot the size of a pea) throughout the day – about 5-8 times a day. I have to take a urine test in 4 days (aprox. 85 hours from now) when I go to my suboxone doctor. I weigh 160 and have a medium metabolism. If I stop using the coke now, drink lots of water, and work out daily, is there a good chance I will pass the test? Is there anything else I can do to help rid my body of the drug? I would really really appreciate someone answering. Thank you sooo much!!!!
