Benzoylecgonine / Cocaine Drug Testing

Benzoylecgonine is the main metabolite of cocaine. It is used in Drug Screening Test. Many factors determine how quickly it gets cleared from the body.

It is also used medically as a topical analgesic and muscle relaxant, as in prescription drug Esterom, which is used for myalgia.

When a person takes cocaine (chemically benzoylmethylecgonine), it gets metabolized in the liver to form benzoylecgonine. The metabolite is then excreted out of the body via urine.

The presence of this metabolite is almost a certain indication that a person has consumed the drug.

Therefore, in cocaine users, benzoylecgonine testing in urine is commoner than testing of cocaine itself.

Time Taken by a Drug to Get Eliminated From the Body

How much time a drug takes to get eliminated out of the system would depend upon:
  • The amount of drug taken.
  • How frequently or regularly you are taking it?
  • Individual body weight and height.
  • Your overall rate of metabolism, which depends on your levels of activity and health status.

How long does cocaine stay in your system and urine?

Cocaine usually gets eliminated from urine in 12 hours. However, if the dose is heavy, it may take about 72 hours. After this period it is usually not detected in urine.

However, there is an exception. If a large quantity of alcohol has also been consumed with cocaine, it takes even longer to eliminate- 5 days approximately. It also leads to the formation of a metabolite called Cocaethylene.

And how long does coke metabolite benzoylecgonine stay in your system and urine?

Benzoylecgonine takes longer to get eliminated. Even if amount of cocaine was very less, minimum time for it to get eliminated is 4-5 days. In case of heavy use, it may take around 10 days. If you are a regular user, even if you take little amounts, elimination time is around 20 days. Again, if alcohol is also being taken along, then around 25 days or even a month are required for complete elimination of the drug.

Taking adequate water helps in speedy elimination. On the other hand, alcohol and caffeinated drinks hold back this metabolite in the body and delay the elimination process.

Threshold Value for Detection

Levels of 2 ng/mL or more produce a positive drug test result.

Half Life

Around 30 to 40% of cocaine or crack is metabolized by enzymes in the liver to form ecgonine methyl ester. Another 30 to 40% is hydrolyzed spontaneously without enzymes to form benzoylecgonine.

Both of them are water soluble compounds and are active. While cocaine has a half life of 1 hour, benzoylecgonine has a half life of 6 hours.

Types of Drug Screening

Saliva test- Cocaine is detectable in saliva after 5 to 10 minutes of taking the drug. It may be detected in saliva till 2 to 4 days.

Urine test- Detectable after 2 to 5 hours of use, till a period of 3 to 4 days.

Blood testing is more specific. The presence of the drug is detected after 5 to 6 hours till around 5 to 7 days or even more.

Hair test- The drug starts showing in hair after 5 to 7 days till around 80 to 90 days.

Urine testing is most popular because it is painless, easy and inexpensive. Home kits available in the market are also based on urine testing.

Detection in Chronic Users

In long-term or regular users, the drug is stored in the fatty tissues, especially of the liver. After each use, a fraction of the drug consumed is stored, adding up to the stock each time.

This stored drug is released on a continuous basis into the blood stream. So the user is detected positive even if he doesn’t take the drug for some time.

Total cleansing of the user takes 5 to 6 months, after which he can be called drug-free.

False Positive Test Results

People often complain of positive results with urine drug testing for cocaine, when they have not taken this drug at all.

This may happen. False positives do occur.

Firstly, it is not cocaine itself that is screened in urine. Actually it gets out of urine in as little as 12 hours, so its testing would be a waste.

The metabolite of cocaine, benzoylecgonine, is screened by most of the testing labs. This shows in urine till 3 to 5 days, or even a month if the dose intake was heavy.

It’s a fingerprint metabolite of cocaine. No other drug or prescription medicine produces exactly the same metabolite as benzoylecgonine.

However, certain medicines produce metabolites that are similar in structure. So labs with cruder instruments may label you as ‘positive’, if you are consuming these medications.

Some of the medications that may produce false positive test results include local anesthetics that are used by dentists, including lidocaine, novocain and tonic water.

Apart from these, patients with chronic liver or kidney diseases may also show altered results.

What to Do If You Get a False Positive Result?

Immediately request for a confirmation test.

The standard EMIT test used by most labs can be confirmed by GC/MS (gas chromatography/ mass spectrometry) test. This detects the benzoylecgonine structure with more specificity, screening out similar looking compounds.

      As said above, the metabolite of the drug, benzoylecgonine, is measured. This metabolite takes around 4 to 5 days to get eliminated from the body.

      The time may be increased when alcohol is taken along. Also, elimination time is more in overweight individuals.

        I licked very little residue from my finger about 5 hours before a dipstick test and the line was faint enough they sent it to the lab. I had not drank hardly anything that day and my urine was very yellow. My question is will the test show up above the limit for such a small amount or will the urine being not watered down at all have caused the line to be so faint?

      It takes around a week to 10 days for elimination. However, if the intake is on a regular basis, even if the amount is small, the metabolite may accumulate in the body.

      In such cases, it may take 15 to 20 days for elimination of the metabolite.

      There is no evidence that vitamin B12 helps in the elimination of cocaine.

    I did about 3 grams of cocaine and I fell asleep around 3 am on Tuesday morning. I woke up around 1 pm Tuesday and started drinking water. I peed once every hour for about six hours. I also consumed about 20 oz of water after each urination.

    Then around 7 pm I bought blueberry pomegranate 100% juice. I drank it all about 2 liters worth. Also around 7 pm I was peeing about every half an hour till 3 am Wed morning.

    I fell asleep and woke up with diarrhea and I threw up. Since then, I have drunk about 20 oz of the same juice and I ate a small fry from McDonald and a liter of water. Note I ate one time on Tuesday.

    I have a drug test on Friday. If I continue with my rate of water and juice consumption, will I be clean ? I consumed no alcohol during the cocaine consumption or afterwards.

      It’s disastrous to take cocaine during pregnancy. Encourage her to leave it completely. Women are advised to abstain from cocaine completely both during pregnancy and lactation.

      It cannot be said if she will be able to clear the urine test. This is because, this drug and its metabolite have a tendency to get deposited in different parts of the body, like the liver, of chronic users. This deposited or stored drug is difficult to get eliminated.

      Since your friend has been a chronic user, things are more difficult for her. Read here about factors that may aid in early elimination of the drug.

      You previous questions have been answered here.

      You have just a weeks time. Take the following precautions. These will aid you to pass the test;
      Drink a lot of water.
      Abstain from alcohol, caffeinated drinks, smoking during this period.
      Stay active. Eat lots of fresh fruits and vegetables.

      It is quite likely that you will pass the test. However, if you have been a chronic (regular) user, nothing can be said. This is so because in regular users, the drug has a tendency to get collected in various organs like the liver. This collected drug is difficult to eliminate.

      It is a blessing that you have decided to stay away from cocaine forever. This is a recreational drug which makes you its prey in a very short duration. The drug is very toxic, especially for the liver, kidney and nervous system.

      You have not taken any cocaine since a month now. This time period is enough for its excretion from the body. Read above in detail about elimination of cocaine and its metabolite.

      However, you may still do the following to eliminate any drug left:

    2. Drink a lot of water. Water is the best cleanser for the body.
    3. Abstain from alcohol. Alcohol has a tendency to hold back cocaine in the body.
    4. Quit smoking for some time.
    5. Avoid caffeine containing beverages for a few days.
    6. Eat plenty of fresh fruits, juices and vegetables.
    7. Since it is our liver which handles elimination of the drug, keep your liver healthy and detoxified to ensure removal of many toxins from the body, like cocaine.

    Hi Buddy. Quick question.
    I took 2 lines of cocaine 2 Saturday nights in a row then 7 days later (the following Saturday night) I was tested. I have been assured by everyone that the metabolite (benzoyleconine) would be out of my system in under 3 days as I am extremely fit. 6’2 weighing 76 kg and have a great metabolism. I am still worried when I doubt I really have to be. This should be enough time (7 days) for such a small amount for someone like me to be clean correct?
    Thanks

      It is quite likely that you will pass the urine test. The drug doesn’t usually show up in urine after 5 to 7 days. Also, there are ways to help you clear the drug quickly from the body.

      Screening is usually done by testing urine. However, there are other more accurate tests too, like blood test and hair test.

      Blood screening may catch the drug. Hair tests show every drug ever taken when that hair was growing.

      Cannot quantify like this. Whatever amount you take, levels rise in the initial few hours. Then, as your system starts metabolizing and excreting the the drug out of your body, the levels would decline.

      Benzoylecgonine, the main metabolite of cocaine, is used for screening. This is detectable in urine in concentrations greater than 150 ng/mL, typically till eight days of the drug taken.

      After quitting the drug completely, your body needs at least a month to clear off the drug. Hair growing within this month would also show cocaine.

      It would depend upon the type of testing done. Commonly, urine testing is done and cocaine along with its metabolites is tested.

      As you may read above, it takes 4 to 5 days for Benzoylecgonine (cocaine metabolite) to get out and not show up in the urine. Blood tests are even more specific and may show it for around 10 days.

      Alcohol holds back this drug in the body and delays its excretion. So, avoid alcohol and take lots of water to aid in early excretion.

      If you can avoid alcohol, caffeine, and other stimulants altogether, there are fair chances of passing the test.

      Cocaine and other similar drugs get deposited or stored in the liver tissues after each use. This stored drug is slowly released in to the blood stream with time. Alcohol helps in holding back the drug in the liver and impedes its excretion.

      It is this stored portion of the drug that is difficult to wash away in chronic users. So, chronic users are usually more difficult to cleanse than one time users.

      You may pass the test if the drug is sufficiently out of your system. This would depend upon many factors like:

      Your metabolic rate
      Overall health
      Whether alcohol was taken along
      Amount of water or healthy fruit juices consumed for cleansing
      Level of physical activity
      Overall caffeine intake, this chemical impedes the excretion of cocaine

    I did consume alcohol with it but I’ve been to the gym several times. Since I do have a fast metabolism and don’t consume a lot of caffeine, it is just strange I’ve been reading a lot of blogs on this subject and there is a lot of people in my shoes asking questions but there is nobody saying they have failed a drug test after that amount of time which leads me to believe that the 2-5 day timescale is near enough right, although that is just me being hopeful.

      It’s nearly five days for one time users. But for repeat users, the time scale may be anywhere from 10 days to a month!

      It’s all about how clean your overall system is. All recreational drugs are stored in the liver and are hepatotoxic.

      Blood tests are more specific. Blood may contain cocaine for a longer time.

    I went to a new pain clinic. I just had 3 brain surgeries due to an aneurysm. The docs had me on a pic line of vancomycin and oral cipro for 3 months. On top of that I took 80mg OxyContin 2x a day and 40 mg oxycodone 4 times a day. I also take lyrica, neurontin, Effexor, Xanax, centrum, norvasc 20 mg, and lidoderm patches. I have Arnold chiari malformation, brain aneurysm, cervical fusions, stenosis, degenerative disc, arthritis in spine, and at the time due to pneumonia was on penicillin NyQuil mucinex DayQuil and my albuterol inhaler. I also just found since all of the antibiotics I was on I have too much protein and blood in my kidneys and I have to go to a nephrologist (renal) doctor because they say it’s serious. Somebody please tell me how in the HELL my pain doc tells me there was cocaine in my system? Honestly I can’t even get out of bed or off the couch. Let alone do cocaine? I have a damn aneurysm and hbp. I demanded it was not feasible and asked for a retest. Also, they sent me a letter of dismissal. I have my lawyer involved now. And I just want to know how the hell this can happen??!! I’m in shock and am now treated like dirt. Somebody please help me. I’m a very sick woman and I need answers..? Thank you and God Bless

      Cocaine is detected by checking the presence of its metabolite, benzoylecgonine, in urine.

      Unfortunately, some of the medicines you are taking, including lidoderm patch and xanac, are metabolized in a similar way as cocaine and the metabolite formed is also the same.

      It is quite likely that your medicines are the reason why you got a positive drug test. Talk to your pain clinic about it. Tell them that lidoderm and cocaine are metabolized to produce the same metabolite, benzoylecgonine.

      Since you are taking all precautions, there are chances you may pass the test.

      Just abstain completely from alcohol, limit to caffeine. Such drinks may hold back cocaine and impede its excretion.

      If you are a chronic user, excretion would be even slower.

      You don’t have much time in hand. The drug requires a week to 10 days to get excreted from urine.

      However, it would be good to try your best. Keep drinking lots of water. Abstain from alcohol and stay active physically. This will accelerate the excretion of the drug from the body.

      There’s a pretty good chance that you would pass if the drug test screens cocaine. Cocaine usually gets out of the urine in a week’s time.

      However, drug tests are of different kinds. There are some which screen benzoylegconine (metabolite of cocaine), instead of cocaine.

      Benzoylegconine takes around 10 to 12 days to get out of urine.

I did one small line on Saturday night, and took a urine test to be sent to a lab this morning (Tuesday) approximately 11 days after. I consumed 8 beers with it and haven’t drank since. Will the metabolite likely show? Or am I fairly clear? Thanks!

      It is unlikely that the drug or the metabolite will show up in your test.

      However, if you are a regular user (chronic user), it may still show. This is because the clearance time for the drug is much more in chronic users than single time users.

    Hi there,

    I am hair tested regularly for legal reasons (child contact etc). I used a large amount of crack-cocaine in October 2012 but metabolites of cocaine were still found in my hair some 9 months later. I have categorically not used cocaine in period. In fact, when you look at the results you can see that the amount of benzoylecgonine drops in a linear fashion over the 9 month period but the doctor says that this is evidence of continued drug use, and now I am not allowed to see my son.

    I am on sertraline and mirtazipine for depression, take the odd paracetamol or ibuprofen, smoke a lot of rolled tobacco (not weed!!) and drink 1-2 cups of strong coffee a day. I don’t use hair products but my hair grows real fast. Thanks. Peter

    Reply
    1. Buddy M.D. Post author

      Very sorry for your situation.

      It is possible for the drug to show up in the hair test even after long periods. This is because the drug and its metabolites are lipophilic (attracted to fatty tissues) and so they stay attached to many fatty tissues in the body.

      This stored drug is slowly released into the blood stream with time. So, the body doesn’t become drug free till all of this drug is released and washed away.

      You need to be strong. Keep patience till the drug is completely out of your system.

      Every hair that grows in the period, when your body had cocaine in its blood stream, would show the drug. So, cutting an inch of hair is not adequate.

      A rough estimate is around 3 months!

      Though the drug would stop showing in your urine in about 20 days, it may show up in your blood, hair etc. It takes 3 months for an overall detoxification of the body and complete elimination of the drug.

    I had a hair test and tested positive for coke, but at a lower level of cocaine than the cut off point. But the metabolite is in there too, thing is I haven’t done any drug what so ever and the only thing I had was prescribed a course of amoxicillin back in Feb, and I know amoxicillin can cause you to test positive for cocaine and that really can be the only thing it can be, I have had a previous hair test and that was negative, and only when I had amoxicillin it went positive and showed in my hair for 5 months but under the cut off level ,any idea you might have.

      If it is the urine drug screening, which is the commonest form of lab testing, you are safe after 20 days or more!

      It is quite likely that the drug is accumulated in your liver, since you have been a chronic user. This drug stays attached to fatty tissues there, and is difficult to excrete out. It takes time to go.

      Abstain completely from the drug. It would be helpful to avoid alcoholic drinks and excess of tea and coffee.

    I recently unknowingly kissed someone who had just had done cocaine. At the time I was also drinking. And after finding out, I did a home test which tested positive for the drug after 8 hrs. I have a hair follicle drug test coming up sometime in March, so that would give me a 90 day window. However, my hair grows very slow, I really do not think a 90 day window would be enough. My question would be, if I have never done it before, and it had to be trace amounts that entered my body, would the metabolites still be in-bedded into my hair? What is the threshold limit that would cause deposition? It had to be less than 1mg because it went undetected to me at the time, but the home urine drug test gave a positive. I know detection limits are very precise for a hair test, however, would such small amounts of cocaine still cause deposition into the hair follicles? I am very nervous regarding this. I have been hydrating myself in the past 3 days, but I do not think that will help. Any suggestions would be helpful.

      No, furosemide cannot be used for this purpose. Taking this pill would just speed up the the excretion of water and certain electrolytes from the body, not cocaine.

      Cocaine takes its time, getting metabolized in the liver first and then getting out of the system via urine. Until it is metabolized, it cannot be excreted.

      Furosemide may disturb your system and make you feel weak, due to loss of essential ions from the body.

      The drug starts appearing in your hair in 2 to 3 days and continues to do so upto 90 days. Variations are there, depending upon the rate of growth of your hair.

      It won’t benefit if you trim your hair. This is so because the drug will start appearing in the part of the hair closest to the scalp. This portion is the newest growth.

    In late November I tested positive for cocaine on a 5 panel hair test. I have never taken cocaine. I was told by the lab’s medical review officer that the only thing that will test positive for cocaine – is cocaine. He also said it appeared that I was a longtime user. After being terminated, I had my own tests done. In December I passed a hair test, urine test and blood test. What on earth would have caused the first test to be so wrong? I have taken Ritalin daily for 15 years. I asked the medical review officer if that could be what the test was picking up. He said no – only cocaine – and called me a liar. I have a million questions but the two big ones are 1. What would cause a false positive for cocaine? Regardless of what the technician said, something had to. 2. Why didn’t the test detect the Ritalin?
    I hope someone can provide some insight.

      Cocaine and methylphenidate (Ritalin) are chemically very similar. Also, their mechanism of action in the body is the same, both target the dopamine system.

      They block the ability of nerve cells to take in dopamine, thus flooding the brain with this joy-inducing chemical.

      Though their metabolites are similar, they are not exactly the same. You can request for a more precise testing (involving gas chromatography), which will be able to differentiate between the two chemicals.

        Thank you. I am told they in fact used GC testing. Since Nov. 26, I have passed 3 five panel hair tests, one of which used body hair instead of head hair. I have also passed a urine test and an extensive blood exam. In addition to the fact that I know I did not take cocaine, these other tests lead me to one logical conclusion – the hair taken from my head in Texas on Nov. 13 was not the hair that was tested in the Kansas lab two weeks later. Instead of asking for the re-test, I should have asked for a DNA test. Do you suppose all of the hair samples would have been destroyed by now? Is there a chance that there would be some remaining strands? Enough to run a DNA test?
        Thank you again for this website. It is truly helpful.

          It’s difficult to say whether all the hair samples are destroyed or not, as it depends upon the lab protocols. Though, most of the labs keep the samples for a pretty long time!

    I recently moved to a new state and am on pain management which includes a prescription of oxycodone. I found a doctor and made an appointment to get refill since I moved to different state. Naturally, since I’m on a high narcotic, he did a urine test to determine misuse of medication. He said that the test had a very faint line for cocaine and has sent it to lab for further testing. Is it possible to have possibly consumed by smoking marijuana out of a friends glass bowl who may have smoked crack/cocaine out of it? I am worried because it could result in not being able to be prescribed my medication. I guess my question is if the line was faint and I did unknowingly ingest it through a piece that could have been used for smoking what should the ng/mg be so when I get my results I can discuss it further with my doctor ( I did mention smoking a few bowls with a friend that could possibly have cocaine residue in it) since I did not snort or smoke crack/cocaine and was shocked to hear that even a faint positive result appeared in my urine.

    1. Buddy M.D. Post author

      Yes. it is possible to get the faint line from specks of cocaine residues in the bowl. Drug testing these days has become very precise and detects minute quantities of the drug taken.

      Alternatively, it may be that you tested positive for marijuana. Some clinics use immunoassay method to simultaneously test the presence of both, marijuana and cocaine. If the patient tests positive, his sample is sent for further, more specific, testing to exactly define which drug was present.

      For most of the labs, the cut off concentrations for morphine metabolite is 50 ng/ml and for cocaine metabolite it is 150 ng/ml.

      It takes 3 to 5 days to be clean in urine testing, if you are a one time user. If they check blood, it stays positive for longer, around 10 days.

    Hi! I’ve read nearly every comment/reply on this web page :) I’d like to thank you in advance for your response to my question and for your responses to all of the other comments~

    15 days ago, my friend snorted 1 “key/bump” of coke. My friend also consumed a considerable amount of alcohol with that “key/bump.” My friend has not ingested coke since, but consumes alcohol daily. After educating myself and my friend of the fact that alcohol does prolong the metabolites produced with coke and alcohol consumption (though we are unclear as to how much this is prolonged), my friend is worried that a pending urine test will result in a positive for the drug/metabolites. The urine test is scheduled for tomorrow. My friend occasionally works out, eats healthy, drinks a moderate amount of water, is a little over weight, and consumes alcohol daily. So our question is this: will the metabolites and/or parent drug show on a urine test after 15-16 days of inhalation?

    Reply
    1. Buddy M.D. Post author

      Though it is quite unlikely to show up after 15 days, nothing can be said for sure.

      There are many variables like, the quality of cocaine inhaled, its purity, whether he had been a chronic user of the drug or was this a one time use, his metabolic rate etc.

    I was a moderate user last year but slowed down to a couple lines a week, not high quality. Last time I had a small key bump was 5 weeks prior to urine test. Also was drinking moderately but also drinking lots of water and eating all vegetarian food. I passed the at home test but the tests get sent to a lab for my job. Think I am clear?

      Drink plenty of water daily. Eat a healthy diet rich in fruits and veggies.

      Till you have drug in your body, evrey hair growing in that period would show the presence of the drug. The body takes around 2 to 3 months for complete cleansing.

      All that can be said is that the drug takes around 5 to 7 days to get eliminated to not show up in the urine test.

      It is difficult to predict the exact period required for elimination of the drug. This is because, this period is variable. It depends upon many factors like your activity levels, health status of your liver and kidney and the type of cocaine preparation taken.

      Anyhow, drinking water and taking fruits helps a great deal. Role of creatinine is not clinically proved.

      If this was a one time use of the drug, there are chances you may pass the test. It may take 5 to 7 days for the body to wash off the drug enough to not show up in urine testing.

      However, in people who take the drug on a regular basis, the drug gets deposited in the fatty tissues inside the body, mainly in the liver. Due to this accumulated drug, cleansing becomes slow.

      The stored drug is continuously released in to the blood stream and this keeps showing in the urine for a month or so.

      The metabolite benzoylecgonine is very specific for cocaine. In all likelihood, you have taken the drug in some form, may be mixed in your drink.

      Since you are a one time user, the drug would be out of your system, enough to not show up in the drug test, in about a week.

      It’s not easy to hide cocaine use, as the metabolite they check in the urine test is very specific for cocaine.

      Apart from this, there are other tests too, like the hair test, that reveal the drug intake even when it is out of urine.

      There is no clinically proven role of Lipozene in the excretion of cocaine. It cleans the gut, not the blood. Cocaine is present in your blood and the only way to wash it out is through the kidneys. We expedite excretion through kidneys by drinking more of water and fresh fruit juices.

      Take only the prescribed dose of lipozene. Too much of it can lead to diarrhea, making you weak. Also, it may give you swallowing problems if taken in larger doses.

      The drug may take a maximum of 3 months time to get excreted out of the system.

      Theoretically speaking, traces of the drug are still there in the body and may take years to go away.

      However, these traces are much much below the threshold levels, and go undetected.

I am 1 week clean off of cocaine as of today and would like to know how long it will take until I am able to pass a drug screen. I do not drink alcohol or use any other drugs, but I drink a can of redbull just about every day. What do you think?

    Another thing or two I thought I might add is that I am a 28 year old male, am in good health, and the drug screen will most likely be a urine test.

    Thank you!

      Since you have been a chronic user of the drug, it’s going to take time before you are clean.

      In people who take the drug on a regular basis, the drug gets stored in the liver and other fatty tissues of the body.

      This stored drug is released on a slow basis into the blood. This maintains a constant level of the drug in blood.

      It takes around three months of drug free interval to clean your system enough to pass the drug test.

      Also, drink lots of fluid. Avoid caffeine and abstain completely from alcohol. Red bull contains substantial amount of caffeine. Try avoiding it.

    ******UPDATE*****
    So I asked on April 7th 2014 what were the chances of passing a drug test from doing a really small amount of coke ( probably 0.1 just one small line) And I went today April 22 2014 and had a pre-employment medical and I passed the test. I drank lots of water but didn’t over do it to the point were I felt nauseous. I also had some sweat exercises like riding on an exercise bike with sweat pants and a hoodie about 4 times ( 5 miles each) also I tried to stay away from alcohol but gave in about 3 times during this period ( a bottle of rum each time) stayed away from caffeine as much as I could, ate lots of fruit cups and bananas. So if your reading this, there’s a good chance you will pass if you have the time and stay healthy and productive after last use. Hope this helps you all.

    I was just curious because I used to be in excellent shape for 10 years straight and my body fat was always around 5-6%. I know it will take longer to get it out of my system but I don’t know if I still fall under that 3 month category. Thanks for the input though Richard.

      It takes around 7 to 10 days to become clean, enough to not show up in the urine test.

      However, the drug may still appear in the blood testing.

    I did coke twice, and the last time I did it was 35 days ago.

    I am overweight and I drink a lot of coffee (like 3-5 cups a day). Even though I’m overweight, I barely eat because I’m drinking coffee all the time. After I did the coke, I felt bad for doing it and didn’t want to even think about the whole drinking lots of water thing, so I just kept on drinking lots of coffee as I usually do and didn’t go out of my way to drink lots of water at all.

    I am going to a rehab in about 3 weeks (for marijuana problems) and I do not want them to find out that I did coke.

    That means it would be a total of 50 days since I last did coke. But taking into account my coffee habit, and being overweight, I would like to ask your opinion if you think I will pass the test. Thank you so much for your help.

      17 days is enough a time for washing off the drug from the body. You just need to take the right steps.

      If you are continually taking all precautions, you have chances of passing the test.

    I snorted about half a gram of coke on Sunday (5/25), morning and drank tons of water while doing so. I did drink some alcohol Saturday night, but only a few beers and a shot. I also, have been drinking wine every night since I did the coke. I may be getting drug tested on Monday (6/2) and I’m somewhat concerned since reading the info on this site. I do drink lots of water and workout everyday as well. However, I am a bit over weight. I’m 5’4 and weigh 180 lbs. I’m wondering what my chances are that I’ll pass the test on Monday? Now knowing what I know from this site I will be cutting out alcohol and drinking a lot more water. If I do this will my chances of passing be pretty good? Also, I hardly ever use cocaine. This is my first time in about a year.

      Cocaine metabolizes and gets converted into benzoylecgonine in the body. This conversion starts in about 2 hours and by 12 hours almost all the cocaine gets converted.

      If they are measuring benzoylecgonine (cocaine metabolite) in your urine, it is unlikely that you pass. However, if they are measuring cocaine itself in the urine, you have chances of passing the test.

    Hi, so I snorted a small line .1-.2 grams 13 days ago while quite drunk. I have a urine drug test later today. I’ve been drinking a lot of water each day, and exercise every other day. Only caffeine has been through some chocolate, and no alcohol since then. Looking at other posts, 7-10 days seems to be the norm, so hopefully I’m in the clear. I’m 6’3″ and 215. I’ll definitely post my results to help everyone else out, since this website is a godsend. Thank you guys so much!

    I had one question though, would drinking coffee on the day of the drug test help in any way? I know it prevents the excretion of benzoylecgonine, but wouldn’t that be a help the day you’re taking your urine test?

    Hello, I consumed about 0.3 g of cocaine, not on purpose, during a night when I had about 10 drinks. I have a drug test in 6 days and I may try to push it back to 10. I have never done cocaine before in my life and wasn’t planning on ever doing it. I have been prescribed adderal, but I stopped taking it after I was reading about cleansing your body etc. Would it be more beneficial to take the adderall to increase my BMR or to try to keep my body completely clean?
    The test is at a hospital, but I believe it is just a screening test. I have read up about diluting urine and putting in vitamins etc., but I don’t want to set off any red flags for them to take it to the lab and perform a GC/MS. Please help, this is a nightmare.

I have a drug test on the 29th. Today is the 17 and I had been clean for two weeks until last night where I did half a gram with no alcohol. I’m a 6’0 245 lbs male, quite a bit over weight.

    Doctor, I drank a drink that was apparently “spiked” with some cocaine. Definitely less than 0.5 g. I have a pre-employment drug screening coming up tomorrow @ 3 pm. I was drinking a fairly heavy amount on the night I did it. I am in very good shape and work out every day. I have never done cocaine before. I bought 2 drug tests for home, the First Check test and the at Home drug test for cocaine and I pass them both.

    Drug test will be about 132 hours after ingestion, 5 1/2 days. I passed the first drug test around 84 hours after and the second at about 100 hours. They listed their screening at 300 ng of BZ. Even though I consumed alcohol, isn’t BZ the longest lasting metabolite to be eliminated after cocaine ingestion? Please help!

    Okay here’s the Thanks for last year. I’ve been smoking crack on Saturday nights. I got a lab test coming up. It will be between 20 and 40 days since last use. It will be a urine test for probation. Will that be enough time for me to pass the test? If I pass, I’m off probation. I smoke pot but I can’t smoke pot because I’m on probation. So I smoke crack cause I thought they didn’t take that long to get off for test. So what pass or not? Thank you for you time.

      Since you have been a chronic (regular) user of this drug, it is likely that your body has focal reserves of the drug at various locations.

      These focal reserves keep releasing the drug slowly into the blood stream, maintaining a constant level of the drug in blood, and hence in the urine.

      You need to detoxify your body completely to assure that your urine is clean. Read above about the various precautions to be observed for detoxification.

      You need to abstain completely from alcohol and caffeine containing beverages. Let fresh fruit juices and plain water be your beverage all the day.

      Eat plenty of fruits and vegetables in your diet. Stay active physically.

      It may take around a month or two for your system to get cleaned.

      Since this was not a one time use, you have used the drug earlier this year, it may take a little longer for your system to cleanse it.

      With all the precautions being taken, it may take around 5 to 7 days for the drug to not show up in urine and around 10 to 12 days for it to not show up in blood test.

    Hi,
    I would like to know what my chances are for passing a random urine drug test that I had to do on Friday morning 08/15/2014 for my employer.
    Here’s the details: I was out partying with a co-worker on Wednesday 08/06/14. I ended up doing 2 lines of cocaine that night. Both lines were approximately 1.5 – 2 inches long. The first line was snorted around 10-11:00pm on Wednesday night 08/06/14, and the second was snorted on Thursday morning 08/07/14 around 12-1:00am. I am a first time user, and I was drinking some Bacardi/Coca Cola that same night. I am 5’7″ approximately 150lbs. I drink plenty of water on a daily basis, take vitamins, but I’ve also been taking 1-2 shots of 40% liquor every night since the night that I did cocaine, up until the night before my test. Hopefully I can get answer before my results come in. Thanks!

      However, consuming alcohol during the cleansing time window would retard the excretion of the drug and its metabolites.

    Hi, I took 2 small lines (.1-.2 max) through Saturday night (12 AM) to Sunday Morning (8AM). Never used cocaine before. I took a test for Probation today (Thursday, 11:30 AM). I did take the cocaine with alcohol but stopped drinking at 3AM Sunday. Haven’t a drink and only a diet coke or two since, the rest water, but not excessively. I took 3 “easy@home” drug tests over a 12 hour span before the probation test. Each test came back negative with bold lines for cocaine. They say 99% accurate and use the same technology as the labs and are FDA approved. My question is, do these home kits test for the metabolite? And do you think if the lab tested for the metabolite, that I would pass? Thanks.

    Your post is really helpful but it lacks references to medical studies. Is it possible for you to cite or give me some information related specially to the part where you say that it may take more than 10 days to completely eliminate the benzoylecgonine from the system. Maybe link the research or give me the name and authors. I have being looking for this info for a while and haven’t been able to find the medical studies to back up a motion to the court.

    Good day,
    I am glad I stumbled upon this post. Your information is very useful.
    I snorted about a .5 grams on (12th sept) Friday night and have a 5 panel drug test to take Saturday (20th sept ).
    my conditions : 1. never did coke for this year
    2. I’m 21 years, 150lbs, 6 ft
    3. moderately active, gym 3-5 times a week and run once a week .
    What do you think my chances are if they test for cocaine and if they test for the metabolite benzylecgonine?
    For both urine and a blood test.

      If you take all precautions, as mentioned above (no alcohol, lots of fruits and vegetables, limited tea/ coffee, plenty of water), you have fair chances of passing the urine test.

      As for the blood test, the results are difficult to predict. However, aggressive detoxification would definitely increase your chance.

    I did a key bump and a line on Saturday, a small line on Friday, and a 2 small lines the weekend prior. Before that, I would take an occasional key bump here and there at the bar.

    How long would it take before I could conceivably pass a urine test? I don’t know when it will occur and I also have synthetic urine on hand for the period of time in between no and not being detected.

      If you take all precautions, like complete abstinence from the drug and alcoholic beverages, you may be able to clean yourself (just enough to clear the urine test) in 15 to 20 days.

      Do drink a lot of water. Consume plenty of fruits and vegetables in your meals. They are the best detoxifiers.

      If you are clean since six months, you are likely to pass the hair test.

      Just trim down your hair as small as possible, so that the sample taken is fresh and free from the drug. The older the hair, more are the chances that it contains the drug.

    I did some cocaine last weekend about 2-2.5 grams over 2 days with alcohol, and I have a urine test in 19 days, and the last time I consumed it was about a month ago before that. I am trying to drink lots of water and eat fruit. I am 5’10 about 175, and I am wondering if I will pass or if I should try to delay it as long as possible. Thankyou very much.

      Just keep taking all precautions during these 19 days. Drink plenty of water. Include lots of fruits and vegetables in your diet.

      Avoid alcohol, tea or coffee.

      If you are aggressive in detoxifying your system by taking all above mentioned precautions, the metabolite is likely to get eliminated.

    I did 3 to 4 grams over a 48 hour period. I drank alcohol the whole time. I stopped on Sunday at about 8AM (10/19), since then I went to the sauna on Sunday. I have worked out cardio based weight training for 1.5 hours Monday and Tuesday followed by 25 minutes of sauna. Each day, I have consumed 2 gallons of water and no caffeine or alcohol.

    I am 5’6″ and I weigh 155 with very low body fat. I plan on working out for the rest of the week. I have a test on (10/29). Will I pass?

    Also, is cardo or is weight training a better way to speed benzoylecognine elimination?

      You have good chances of passing the test.

      Exercises of any type would mobilize the drug. You may do cardio, walking, swimming, aerobics or any other form.

        Thank you Buddy MD –

        Last question. I just took a urine home test with a 300ng/mL cutoff and the negative line was moderately faint, but there. The only problem is I think my test may be on Monday (10/27).

        I will continue my workout routines. Do you think I’ll be okay?

    I’m 26 years old, 270lb. I use cocaine and in 7 days I have drug test. Do you think that I will become clean in those 7 days?

      You need to be very agressive about taking all precautionary steps for cleaning. Then only, you’ll have a chance.

      Drink plenty of water. Avoid alcohol, tea, coffee and other stimulants. Include lots of fruits and vegetables in your daily diet. They are the best detoxifiers.

    Hello!

    I used crack heavily for around 8 months. I have been completely clean for more than 5 years. I will be having an extensive physical test for a job I’m applying and my concern is that there will be any trace of it in my lungs, liver or heart. Do you think I am at risk of my drug use to show in my physical after all these years? If so, is there anything I can do to try to correct it and pass my test? They won’t do hair follicle test, but I’m scared that my physical will give away my past drug use.

      You are not at any risk. All chances that you’ll pass the test.

      It is very difficult to detect drug abuse done 5 years back.

    If a person smoked a ten dollar piece of crack cocaine on Friday, will my saliva test be clean on a Tuesday or is 60 hours enough time?

      If this was a one time use of the drug and you have been aggressive in detoxifying your body during these 60 hours, you may pass.

      However, if you are a chronic user of the drug, it is difficult to detoxify yourself in 60 hours.

        I’m not a chronic user, but I did smoke before. Then I smoked a 20 piece that on Monday. Will I have a chance of being clean?

    I just hit a crack pipe for the first time in 40 days. How soon before it is detected in my system, if I urinate within an hour after smoking it can it be detected?

      If you are a regular user of the drug, detoxifying so early is difficult.

      However, if this was a one time use of the drug, you have chances to pass. Keep taking all precautions, read above.

      Though you have a very small time window, detoxification is still possible.

      Take all precautions. Abstain from alcohol. Limit your intake of tea and coffee. Let water be your beverage each time. Drink plenty of it.

      Eat lots of fruits and vegetables in each of your diet.

    I kissed and has sex with a girl who had just done cocaine. I had a urine test the next day. Would that show up?

      If she had cocaine specks in her mouth that may have entered yours while kissing, the drug may have entered your system.

      However, there are more chances that you’ll be tested clean.

      Hair test are very precise. If it’s showing you positive, may be you took the drug unknowingly. May be from contaminated utensils etc.
