Cocaine Clearance Time in Long Term Users

Q: I am 32, 5’4 about 180 lbs. I was a “few times of week” user of cocaine. I would smoke it, mixed with tobacco. Last time I used was 10 days ago. I have to take a urine test. I have been drinking water and cranberry juice. How likely is it that I will pass this urine test tomorrow?

After a one time session of the drug, cocaine and its metabolite usually take 4 to 5 days to get eliminated from the body.

However, since, you have been a chronic user of the drug, nothing can be said for sure.

With repeated doses of cocaine, the elimination time gets doubled. This happens with each dose. So, after the second dose taken, the elimination time is a week, after the third dose it is two weeks and so on.

Why Does This Happen?

In chronic (long term) users, the drug gets deposited in different organs of the body, like the liver etc. The drug has a tendency to get deposited or dissolved in fatty tissue present in the liver, subcutaneous fat and elsewhere. This deposited drug is difficult to eliminate.

Usually, a drug free time period of 45 days is required to assure that the drug would not show up in the urine test of chronic user.

Blood tests are even more accurate. Hair tests are sometimes done which show every drug ever taken when that hair was growing.

    If a person just sniffs cocaine just to try it for 1 time only, for how long will it appear in his body? If it still appears on his hair for 3 to 6 months can he cut his hair really short or it’s useless?

      For one time users, excretion is usually quick. The exact duration would depend upon the amount of cocaine takenand whether alcohol was taken along.

      Alcohol, beer and caffeine delay cocaine excretion. They hold back the drug in the body.

      Speaking generally, you are likely to be drug free (for the urine test) in about 10 days. However, blood test may still show the drug. It would take another 5 to 7 days for the drug to get out from blood.

      Hair test are sometimes done. Every hair that grows in the period when the drug was present in the body is likely to show the drug. So, to get the drug out of your hair, you need to get yourself shaved off repeatedly or carry very small hair. Repeated cutting of hair is required for a month or two.

      Passing the drug test is dicey, since the amount taken was quite a bit.

      Home drug tests are quite accurate, around 90 to 95%. You may try one at home to assess yourself.

      Drug tests are of many kinds. The urine testing is the commonest of all, done by most institutions and employers. Blood test are more specific and the drug shows in blood for a longer time.

      If you stay absolutely drug free now and have a healthy diet rich in seasonal fruits and vegetables on a daily basis, you are likely to get cleaned by 3 to 4 months.

      This is the time required by your liver to detoxify you. Do go for being drug free!

      Read above for the time estimate to be drug free.

      Detoxification is basically a process involving mainly the liver and the kidneys. The aim is to mobilize all deposited toxins from the body and finally excrete them out.

      In a natural way, this happens when you consume plenty of fresh fruits and vegetables in your meals on a daily basis.

      Avoid alcohol and caffeine, as they help these toxins to staying inside the liver. Drink lots of water. It also help if you stay physically active throughout the day.

    I used cocaine, I say frequently but on the weekends and not every one for about 15 years and have been clean for about 6 months. I went to the bar and snorted a total of about 1.5 grams over 2 weekends about 30 days ago. Very low quality. I now have to take a hair follicle test for a job. What are the probabilities of passing this test? 35yrs old 5’11 290lbs. I know I’m fat. Total time being clean before test will be about 5 weeks.

      Since you have been a chronic user, it is very difficult to predict the results of your hair test.

      The blood of chronic users continue to carry the drug even after leaving its use for around 6 months. This is because the drug stored in the fatty tissues, like liver and body fat, keeps releasing the drug in small quantities.

      This drug, present in blood, goes to all the organs along with blood and may show its presence there.

      Hair shows every speck of drug present in blood till at least three months of use.

        I thought that it only stayed in your blood from 5 to 10 days, so my question is that with that theory if I took a blood test 4 months later then it would still show use of the drug?

        1. Buddy M.D. Post author

          It’s 5 to 10 days in one time users only. In regular users, the drug is deposited in the liver and other fatty tissues on a regular basis.

          This stored drug is released into the blood stream in minuscule amounts on a continuous basis. This may continue for a long period of time.

    My boyfriend is on probation and must submit to a drug test once a month for use of cocaine. He has had two drug tests and has tested positive for both. As a result they have determined him in violation of probation. The truth is he has not used cocaine since he was put on probation. I have read your articles explaining the presence of the metabolite benzoylecgonine for quite some time after a person stop using cocaine. In an effort to argue the validity of being determine in violation, my question to you is how long do you think (best guess) my boyfriend will continue to test positive even though he has not used cocaine. He is 59 years old and weighs 230 pounds. He has been using cocaine for over 40 years. Up until the time he quite he did a minimum of 2 grams a day, everyday for 40 plus years.

      Let us know exactly, since how many days has he left using the drug.

      In chronic users like him, it may take around a month for the drug to not show in urine test.

      The drug stays longer in blood. It may take another 15 to 20 days for it to not show in blood.

        It has been approximately 18 days since he had used the drug. In your reply you said it might take a month not to show up in a urine test. Now I’m a little confused. I read the facts and info your website provides on cocaine. It said that chronic users could take up to 4 months after no longer using the drug before the metabolite, Benzoylecgonine, stored in the fat cells and the liver are actually eliminated. It also said during that time the body is releasing the metabolite into the system. I assume that is because the body is being deprived of drug and is trying to compensate. Could this time frame come into play in this situation or were there other factors considered in your assessment of time for a Chronic User?

        1. Buddy M.D. Post author

          Yes, it may take longer than a month for cleaning. It may take around 3 to 4 months.

          Exact approximation is difficult, as many factors come into play when the excretion of the drug is assessed. Was he taking alcohol with the drug, what is his rate of metabolism, his overall health status etc.

          The drug stored in the fatty tissues, when it was being taken by him on a regular basis, is resistant to excretion. This drug stays sticking to fatty tissues and is slowly released in the blood stream. This may give a constant level of the drug in blood, though he is not taking the drug anymore.

      Have you been using the drug often? If yes, it’s difficult to be clean so soon.

      If not, you have chances to pass. Drink plenty of water to wash off the drug from the body. Avoid alcohol, smoking and caffeine.

    If I have used cocaine 3 times in a month but every time I used it I did like a .2 or .3 at most would I be considered a chronic user? I have a test in 3 days and did a .2 of a gram 5 days ago iv been drinking water and sweating a little more than normal also I smoke cigarettes every day I weight 160, and 5″11 what is my chance to pass? Also would laxatives help get it out my system and faster?

      Laxatives donot help in excreting out this drug.

      Flushing it out via kidneys can be does by drinking plenty of water. Avoid tea, coffee and alcohol.

      Though not a heavy use, this cannot be taken as a one time use.

      How many days do you have after the last usage of the drug?

      Results would depend upon how much you managed to flush the drug out of your body during those 9 days. If you’ve been aggressive enough, you’re likely to pass.

    Hello, my friend is an athlete and very active with cardio+weight training and sweats a lot regularly through rigorous exercise. He also consistently maintains a healthy diet. He has an athletic and muscular lean body. He’s about 5’9 and 170 pounds.
    He made a mistake and did about .5 of cocaine with some alcohol about 2 days ago at a concert. He has a blood and urine drug test in about 1-2 months for a government agency. He has done cocaine in the past recreationally. Would he be able to pass both drug tests with no trace amounts in this amount of time? Remember that he is extremely physically active and eats clean with lots of water. Thank you for your time.

        For the past month or so he would do it about once or twice a week. Before that he had stopped completely for about six months. But prior to those six months he was a regular user for about a year. He’s on a mission to get rid of any trace amounts lingering in his system and is aggressive with his approach to cleanse and detox. Is it possible for him to pass his government urine and blood drug test with absolutely no trace amounts of cocaine in his system at all? His drug test will be in about 1 1/2 – 2 months. Thank you again for your time.
