Urine Test for Cocaine Clearance

Q: I’m 24 years old. I am in very good shape and I do exercises every day. My metabolism I think is way too fast and I eat healthy. I did some cocaine for first time in my life and 13 days later I took a urine test. I’m very concerned about it because I can’t loose my career if something goes wrong. I regret that. Do you think that the result may show up positive after 13 days of it’s intake?

It is quite unlikely that the test would show positive. 13 days are usually adequate for the drug to get eliminated from the body.

However, there are condition which impede the clearance of the drug. They are:
  • The amount of drug taken was big.
  • Consuming alcohol on a daily basis. Alcohol, when taken, holds the drug back in the body.
  • Any liver or kidney disease.
If you have any of the above conditions, the results of the test cannot be assured.

    I was drunk and did a small bump of coke. This was the only time I’ve done it in 7 years. I was so drunk I immediately threw up after the line I did. Will it show positive on a hair test 6 weeks later? I didn’t feel anything from it. My nose and throat weren’t numb and I didn’t get high.

      Usually, this test is done very precisely and shows every speck of the drug taken.

      Alcohol, when taken along the drug, tends to hold it in the body and delay it’s excretion.

    I have done cocaine on and off for the past three months. The most recent would be two bumbs 4 days ago with lots of alcohol. The last time I had it would be one month ago but it was a little over a gram with lots of booze. I want to get a new job but the pre-screen using hair. I am 29, 6 foot, decent metabolism, and have thin blond hair. My hair is currently 2 inches long. I plan to get it cut to 1/2 inch and let it grow out for a month before the test. What else should I do to make sure I pass?

        Difficult to quantify! The assimilated drug depends upon the form in which it is taken and the mode of administration (oral, inhalational) of the drug. Also, small doses taken over a long period can give the same levels like a single large dose.

      Abstain yourself completely from cocaine. Also, avoid drinking as much as possible, as alcohol has a tendency to hold back the drug in the body.

      Try detoxifying your body by drinking plenty of plain water, and consuming fresh fruits and vegetables.

      In a month of clean diet, your system would be quiet clean.

      As for the hair, you would have to shave them off completely to be sure they are drug free.

        Hi there, I did 2 small lines of cocaine last Wednesday night and drank a lot of alcohol with it. I have not done the Drug in a very long time. I will be having a drug test on Thursday morning, so it is about 8 days time. The test is a simple urine kit test not a lab one. I am active and am about 6 foot tall and 220 pounds, mostly muscle. Been drinking lots of water and cranberry juice. Do you think I will pass? Thanks.

    Saturday night I was out and drank a few beers along with maybe 6-8 small cups of hot sake. Maybe another 2-3 shots of alcohol too. A lot of friends were doing cocaine and I never have done it in my life but sometimes I will put my finger in it and rub it on my gums. A very small dab is all I did and by that time it was around 3 or 4am. It is now two days later I have been drinking lots of water and I have a drug test in about 10 hours. Should I be OK?

      Rubbing on the gums may also be called ingestion, as the drug does go into the system.

        Not first time user, last time used was on New Years, so hefty break and was tested previous Tuesday and passed with 2 very dark blue lines. Also consumed a fair amount of alcohol during the time of consumption, do you have any other advice? Ever heard of Certo working the fruit pectin? Thanks a bunch.

        1. Buddy M.D. Post author

          Certo fruit pectin is not medically used for any kind of detoxification.

          However, people have been using it before drug testing. Basically, certo fruit pectin does not detoxify or clear the cocaine metabolites. It may just act as a masking agent. It may bind with certain radicals and mask the results.

          Since you are not a regular user, it is very likely that you actually clean yourself by the precautionary steps you are taking and clear the drug test. No masking agent is required.

    Did some coke about 15 days ago, small amount prob .5 with a lot of alcohol. Did a liver cleanse for 4 days by drinking a crazy amount of water and different juices. Also going in a Sauna/hot tub for 2 hours a day. I’m super active work out all the time but I was a chronic user for about 1yr three years ago. Off and on since small amounts. I’m 25 years old and been drinking alcohol almost everyday. What are my odds if my test is in 2 days? 17 days total.

      It is difficult to comment on the results of your test, since you have been a chronic user. Long term users usually have stored drug in their liver, which is released on a slow basis in the blood stream.

      Since you are taking all possible precautions to detoxify your body. You do have a chance to pass the urine test.

        Thanks for your comment.. I’m looking into the first check home drug test and it’s saying 2-4 days max with cut-off level at 300ng/ml. This test can detect in urine. When they process my urine at a lab is it more accurate? How much more than first check? And is this first check home test really worth it, and as accurate as they say? And being that I’m in good shape, and super active, it should really speed up the process on eliminating the drug? I’m 6ft 180 and 17/18 days seems like more than enough time? For a small amount.

          Home drug tests are quite accurate. Most of the lab tests are similar to home drug tests and check the cocaine levels till a max cut off at 300ng/ml.

          However, some sophisticated labs may check the levels till the cut off 150ng/ml.

          It does matter if you are physically active. Just continue with all precautions you are taking and stay active throughout the day.

          You have fair chances of passing the test.

    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.

    Is it possible to test positive for cocaine from a limited exposure of second hand crack smoke. I had very minor exposure in a large room and not sitting close to another user. On two occasions in the prior three days. I tested positive for cocaine on a dip test and now my urine is being sent out. I have also been taking medications for bronchitis including 100 mg benzonatate. Could this compromise the test?

      Regular users have this drug stored in their fatty tissue deposits. This stored reserve of the drug is slowly released into the blood stream on a constant basis, maintaining a certain blood level of the drug in blood.

      Blood, at no point of time, is absolutely clear of drug.

    I keep testing positive for cocaine during my last 2 urine tests. I’ve been clean for months so the positive results are disturbing, however I’ve just looked on the Internet and the findings are obvious why the positive results. Firstly, I’m diabetic and secondly, I drink lary amounts of water including tonic water, both of these says the net can give positive results, any explanation from yourself, thank you.

      The metabolite of cocaine tested during the urine test is very specific for cocaine. Being diabetic or taking tonic water is unlikely to give a positive test. Most of these test check benzoylecgonine, produced only when cocaine is metabolized.

      May be you inhaled the drug unknowingly, or used utensils contaminated with cocaine for cooking.

    Hey there doctor, So I went out with my boys drinking alcohol and on Friday at 7 p.m. I snorted 2-3 small lines adding up to maybe .2 or .25 grams of cocaine. I continued drinking Saturday and Sunday, but was eating large amounts of food and water throughout this time. Monday I spent the entire day drinking Pedialyte and water, and throughout the entire night waking up every hour to chug 6-12 Oz of water peeing every 5-20 minutes. I’m 25, about 180 lbs, 5’8?. I’m a first time user, as well as in very good shape (gym everyday with runs every morning). I’d say my metabolism is very fast as I’m in the military. I took a urinalysis Tuesday at 10:30 A.M after peeing several times that day. Many people have told me I should pass no problem after 87 hours even with Alcohol involved. Could you please give me your professional opinion as I’m freaking out over this considering I never do drugs. Thanks again.

      First time users have a better chance of passing the test than regular users. You have been very aggressive in detoxification.

      Since you have been taking lots of water, you have some chance of passing. However, it cannot be said for sure.

        Okay, so even with the combination of alcohol it’s feasible for me to pass at this time? What would you say about it in terms of percentages? Technically, the alcohol slows down the processing of the metabolite of cocaine?

        Thanks again.

          Taking alcohol is definitely a negative factor in your case. It retards the excretion of the drug by around 10%

    I did a small line of coke on Oct 4 and another on Oct 18. The last time I did the drug was 20 years ago. I have liver problems and I have a drug test tomorrow. Do you think I will pass?

    I snorted less than a gram earlier this evening (Friday). The earliest I would have to take a UA would be Monday at 7pm. I have been drinking water and taking milk thistle and I plan to drink lots of water for the next two days. will I pass?

      If this was a one time use of the drug, you have a chance to pass.

      Just be aggressive about detoxification.

    About 2 months ago, I snored cocaine about I would say .8 grams maybe a little more. It has been about 2yrs I haven’t touch cocaine since I last did it, but just this 2 months ago. I am expecting to do a hair test tomorrow would it come out?

    I smoked about $500.00 worth of crack cocaine and need to know if I shave all of my hair (head and body) 15 days after I last used, will the new growth of hair be drug free if tested?

      The new hair that would grow back may still show the drug!

      It takes around 3 months for the drug to be washed away from the body, enough to not show up in the drug test.

    I am 130 lbs female over age 50 smoked $300 of crack 7 days ago. Will it show in a 10 panel drug screen? I drink lots of Pepsi, coffee and hot tea no water. I have several small loose bowel movements a day. Not sure if it will be urine or blood test.

    I have used a lot of cocaine in the last 3 weeks. I haven’t used since Friday morning. I have to drug test Thursday morning. How do I get the cocaine out of my system? I have to pass this urine test.

      It’s difficult to detoxify in such a small time window, since you have being a regular user of the drug for 3 weeks.

      Read above about measures to be taken for cleansing.
