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.

        Hi, thank you so much for make me able to ask you a question, I’m on formal probation. I don’t know why but I did around 0.8g of coke between 3 days. 18 days ago was last use, I took a drug test today and it still came up positive!! But it’s strange because a week after I did some I tested almost negative, and it seem that it’s not going down. I have no idea what to do. I need to take a drug test Friday at 1 pm. Right now it’s tuesday. Since 6am I drank half a gallon of cranberry juice, a gallon of water, if I keep doing this till Friday would I be clean finally after 21 days? Thanks you. Hope you will respond me ASAP.

    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.

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.

    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?

        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 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.

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.

    Hi I’m 160lbs 6’2 and I have a high metabolism. I never did cocaine in months but 2 days ago I was drinking liquor and beer and did 3 bags of cocaine and the other day I never drank but did 5 bags in the morning and stopped doing it around 6:00 pm and I never ate nothing all that day. Since today, I drank 6 liters of cranberry juice and planning on drinking pickle juice and water and I may have a drug test tomorrow will I have a chance of passing? Thank you.

    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%

    Hi doc,

    I have a urine test upcoming tomorrow at 1:30PM. Last time I used was the 7th – 2 grams and the 8th – 1 1/2 grams. Before that I did roughly 3 grams on 7/1. All with alcohol involved.

    I’ve been detoxing the last few days drinking a ton of water. I also took 3 drugs tests over the last few days (2 first check, 1 quick screen). All came back negative and the first one was taken on Saturday evening (it’s now Monday). I know all of these tests are designed to pick up at 300 ng/ml but I heard my test is going to be at 150 ng/ml at Labcorp?

    What are the chances that I will pass? How long does it usually take to drop the metabolite levels from 300 to 150?

          It depends upon your rate of metabolism which is also affected by amount of physical activities and diet.

          In general, with plenty of exercises and continuous fluid intake, it may take 2 to 3 days to make it low to 150.

            Lastly, the 2-3 days to get from 300 to 150/100 is taking into account that I had been a weekend user for some time now. Most likely 3 grams a weekend for a two years and a moderate physique?

            I had my test pushed back till Friday (a total of 12+ days clean) to ensure I am clear. It’s for an important job that I can’t afford to not get.

            Again, clean home tests with faint lines on Saturday evening, Sunday afternoon, and Monday and Tuesday morning. I think I am good but just need to ensure that is the case

            I truly appreciate your expertise and knowledge! Thank you!

          3. Buddy M.D. Post author

            12 days should be enough. However, after hearing about your weekend usage of the drug, it’s suggested that you be aggressive about cleaning all those 12 days!

            Abstain from alcohol. Drink plenty of water, fruit juices throughout the day. Fresh fruits and veggies are the best detoxifiers.

          4. Monty

            Thank you and I understand your point on the weekend usage. It is very concerning overall and I can confidently say that the stress of this is leading me to make various changes, including eliminating this devilish substance from my life!!!

            What are your thoughts though on passing the 4 at home tests that I had taken, even though they were testing at 300 ng/ml, I did in fact pass. Saturday evening was the first one that I took and I passed that, then subsequently on Sunday, Monday AM and Tuesday AM. Passed all of them and purchased 2 different brands to verify those results.

            I know my test will be looking for 150 ng/ml, but I felt confident that I would be able to pass after I passed the test cleanly for 300 on Saturday (leaving me roughly 5 days from the time of that test) as well as Sunday, Monday and Tuesday.

            Again if the elimination time of 5 days isn’t enough to get from 300ng/ml to 150 ng/ml, that’s the only possible way that I would fail.

            Thoughts and thank you again for your time and expertise!!!

          5. Buddy M.D. Post author

            Home tests are quite accurate!

            Hi doc,
            I’m trying to determine what percentage of cocaine is broken down into metabolites and what are their corresponding percentages, when estimating a users half life.

            I’ve read that the main metabolite, BE equates to ~30%-40% of the total amount of the cocaine taken. If that is the case and we are trying to determine half life of BE for a urine test, would it look like this…

            Hypothetical:
            1 gram of cocaibe = .3 – .4 grams of BE.

            When calculating estimated half life should the .3-.4 amount be utilized for the half life calculation? (Assuming a half life of BE at 6 hours on average). Meaning, instead of entering 1 Gram as the amount taken, should .3G-.4G be entered instead into the half life calculator equasion?

            Looking forward to your reply!

    Im worried because when I was in Peru one day for vacation with a group of students I had altitude sickness and the tour guide of our group gave us all coca tea this has the alkaloid for cocaine, I took less than a half of a sip, barely a half of a sip, more so just wet my lips, with it…

    but this was before he told me that it had coca in it.

    I literally ran to bathroom a few minutes later and made myself throw up for 20 minutes bc I was scared about having ingested any form of the metabolites from cocaine since coca leaves are used to make coke. This was 8 days ago, however I may have a urine or hair test on September 7th (in 3 days). Im wondering if I have any thing to worry about? The total time since the incident before the drug test will be 11 days. Also, not even sure if the tea had time to soak in the water because as soon as he gave it is when i took a baby sip. Thanks again.

        Did 4 bullet bumps .2 g while drunk on night of September 8, after exercise everyday ran 3 miles or worked out, drank plenty of water at least half or a gallon of water a day, however I take preworkout of 350mg of caffeine and I drank alcohol during the cleansing period at least 3 times just a beer or 2. It now has been 12 days.. I have been drinking a lot of water that I’m pissing every 25 min. I’m 36 5’9 160. What are my chances passing a 150/ml test

    I did roughly 2g of coke on Wednesday night early Thursday. That was 62 hours ago. I might have a urine test by next Thursday which is 5 days away. I exercise regularly and drink lots of water. Last time I used was 10 months ago. I drank about 15 beers while doing it. Is that enough time to pass?

    Did a finger tip of cocaine on my gums on Saturday night while drinking. Have a drug test Thursday of Friday. Haven’t used cocaine in about 4 months before that. What are the chances of passing a 150 ng urine dip stick test for cocaine?

    Done about 3 grams of coke the past 3 weekends. Workout everyday very intense and take pills that speed up metabolism. Had a test about 110 hours after last use and passed a home test later on that same day. What are my chances of passing?

    I rubbed about a fingertip of cocaine on my gums & tongue last night and taking a home urine test in the morning, less than 12hrs apart, maybe like 6 hours in between tasting & testing. Do you think I used enough for it to show positive?

    I had a small dab of coke and rubbed it on my gums Tuesday morning. If I have to take a 150ng/ml drug test on Thursday afternoon, is it likely that I’ll pass?

    I’m 35yoa, 182lbs, athleticly healthy. And panicking out of my mind. I don’t indulge in cocaine or any drugs with the exception of alcohol. On Sunday morning around 345am I licked the tip of my pinky finger and put a very small amount of cocaine on it then rubbed my gums with it. I ended up having a pop urine drug test at 1145am Tuesday morning approximately 32hrs later. Would I pass that test?

    Monday I smoked about 0.2 gm or less. (2 hits). I’ve drank tons of water. I drank 2 beers Tuesday, a gallon of water Wednesday and half gallon water today thursday. Took a test going to the lab this afternoon. So it’s been about 70 hours. Am I likely to pass.

        Would depend upon whether or not you’re a regular user of the drug. If not, you’re likely to pass a urine test.

    I saw from other posts that you would like more information about my use history I would not call myself a heavy user that last time I used coke was a month ago and like the above-mentioned question I only use a gram at a time spread out over the weekend. I guess you can say I use once a month but have only used three grams in the last six months like I said I’m not a heavy user so if I use my regular amount of one gram over a three-day weekend and have 108 hours of clean time then take a pee test will I be able to pass

            It has been 7 days since I have taken the pee test and I haven’t heard anything from the office yet I was told that I would be notified if they got a positive results so I think I passed is it true they only contact you if it’s positive

      Would also depend upon how well to tried to flush out the drug from your body after the last use.

      Since time available was very less, it may be difficult to pass.

        Get your hair trimmed to shorter lengths, as the older hair may show up the drug.

        You’re likely to pass.

    A friend did roughly less than half a gram of cheap street stuff the other day and had a 150ng UA roughly 52 hours later. She is not a regular user. What’s the likelyhood she passed?

    It should have read.. Friend is 5’8? and 175lbs. Did 1 gram of cocaine while drinking. He hasn’t been drinking a ton of water but also hasn’t been drinking any alcohol since the day he consumed the alcohol/cocaine. No exercise done. He has a drug test 216 hrs (9 days) after the day he did it. Will he pass?

      Since he didn’t take any alcohol during those nine days, it’s quite likely that he’ll pass a urine test. Blood clearance may take longer.

      Do update us about his result.
