How Long Does Cocaine Stay in Your System? Benzoylecgonine Drug Detection Test

Cocaine becomes detectable within 2 to 3 hours of its intake in our body, and may be seen till around 3 days. So, its clearance takes around 72 hours, though it depends upon many factors. The elimination time may be much long if the amount consumed is heavy or you’re a frequent user.

Benzoylecgonine is the main metabolite of cocaine. It is also its signature metabolite. 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.

Benzoylecgonine may be visible in your system longer than cocaine itself.

Factor Affecting Time Taken For Drug Clearance

How much time a drug takes to get eliminated out of the system would depend upon:
  • The amount of drug taken
  • The purity or quality of drug consumed
  • How frequently or regularly you are taking it
  • Individual body weight and height
  • Level of physical activities
  • Eating and drinking habits
  • Your overall rate of metabolism
  • Condition of your vital organs, particularly the liver and kidneys.

When a person takes cocaine (chemically benzoylmethylecgonine), it circulates in blood to reach all body organs.  It reaches the liver to get metabolized and gets converted into a metabolite called, benzoylecgonine. The metabolite is, finally, excreted out in urine via the kidneys.

Cocaine Elimination From Your System

Cocaine elimination starts as soon as it enters the blood stream. The chemical is recognized as hazardous by our live, which quickly breaks it down into smaller metabolites.

If the dose taken is very small and you are one time user of the drug, you may get rid of it in less than 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.

Cocaine And Alcohol- A Deadly Combination

It is common among users to drink heavy while they use cocaine. This Combination potentiate the effects of cocaine. Toxicity of the drug is increased and effects last much long.

Liver metabolizes the two chemicals in combination, to give out Cocaethylene as a metabolite. This chemical is very difficult to eliminate from the body. It stays much long than cocaine and its metabolites.

For a one time user of the drug, who has also taken alcohol, it may take 5 days, as opposed to 3 days for cocaine alone, to cleanse the body enough to pass a urine test.

Coke Metabolite – Benzoylecgonine

Benzoylecgonine takes longer to get eliminated than cocaine. Even if the 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 as long as 10 days. If you are a regular user, even if you take little amounts, elimination time is around 20 days. This happens because when the drug is used frequently, a portion of it gets stored in the fatty tissues of our body. This stored drug is very difficult to clear off.

Again, if alcohol is also being taken along, then around 25 days or even a month are required for complete elimination of the drug.

Dos To Speed Up Cocaine Clearance

  • Drink Plenty of water. This would help your kidneys filter out the toxins more efficiently.
  • Stay physically active. This helps you sweat out and also increases the baseline metabolic rate. Both these factors would help in speedy cleansing.
  • Include fresh fruits and vegetables in each your daily meals. They work are excellent detoxifiers.

Don’ts That Delay Cocaine Clearance

  • Abstain from alcohol, while you’re cleansing yourself off the drug.
  • Limit intakes of caffeine, this means avoiding excess tea, coffee and caffeinated soft drinks. These chemicals interfere with the breakdown of the drug in the liver, delaying its clearance.
  • Avoid fatty food stuff,  junk food, processed foods, chips etc. This is to avoid any extra load over your liver and let it concentrate on cocaine excretion more efficiently.
  • Avoid any other drug or pills you’re taking, unless prescribed for some medical illness.

Threshold Value for Detection

Usage is detected by screening for Benzoylecgonine. A threshold level set at 150 ng/mL is used by most labs.

More precise testing may set the cut-off is set at 100 ng/mL.

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 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.

Why Do Chronic Users Take Longer To Cleanse?

In long-term or regular users, the drug is stored in the fatty tissues, especially that of the liver and subcutaneous fat that we have under our skin. 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 hasn’t taken the drug for some time.

Total cleansing of the user may take as long as 5 to 6 months, after which he may 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 is certainly possible. 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 is not that reliable.

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 those 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?

If you’re sure that you don’t have cocaine in your system, immediately request for a confirmation test.

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

      You have 7 days in hand. If you continue observing all precautions mentioned above, you have fair chances of passing the test.

      Keep drinking plenty of water. Have vegetables and fruit juices with your meals. Stay physically active.

      Having a bladder full before you give your sample urine may help. This is because it dilutes the urine sample.

    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!

      The drug and its metabolites take around 5 to 7 days to get out of the system, enough to not show up in the urine test.

      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.

      Since she has been a regular user of the drug, her body and her baby’s body is fully contaminated with the drug.

      The fatty tissues in the body tend to catch and store the drug in them. This stored drug is difficult to wash off. It is released into the blood stream on a slow basis, to give a constant level of the drug, even if it’s not being taken.

      Ask her to abstain completely from the drug. Also, no alcohol, beer to be taken.

      She’ll take around 2 to 3 months to become clean. She has to be very aggressive in detoxification, if she desires to be clean by labor.

      She needs to take plenty of fruits and vegetables in her diet. Avoid tea and coffee. Drink plenty of water.

            OK, so I was gambling that I wouldn’t be tested or, that the head shop solutions weren’t reliable, for my initial interview assessment for the DWI SATOP program (otherwise known as SROP; serious repeat offenders program) for 3rd DWI offenders. That didn’t go so well. I last used on Fri 11/7 and gave a urine sample today, Mon 11/10. It wasn’t a rapid, they sent it of to a pee-pee specialist. I’ll find out in a few days if I passed but (since this site has informed me that most tests search for Benzoylecgonine). I’m not counting on it. It’s OK, the counselor said they don’t hold the initial drug screen against you, they just want to see that your contaminants are decreasing in levels. I’ll keep you updated when I get the results. My next test is hopefully an employment test for Friday 11/14 (which means a full week for detox)! I had a few glasses of wine after meeting with the SROP counselor tonight and bought a cleansing solution at the local head shop for $35. I’ll keep that handy for the pre-employment drop. I’m going to follow all Dr recommendations from here on out. Niacin and Riboflavin here I come! Thanks a million for the advice, doc! Stay tuned for more updates.

    I had about 1 gram of cocaine on the 5th October, then on the 25th I had about .5 of a gram. I had a urine test on the 10th of November. Do you think I will pass? I’m 6,2 and 107kg, go the the gym daily and drink plenty of fluids but I drink energy drinks and beer a couple of times a week.

    I had 1.5 grams of cocaine on 11/10/14 and like 6 or 7 beers the last time I have done cocaine was 10/6/13 so I have been clean for well over a year. I am currently on vacation from my job but we get random tests. Should I be clean when I return to work on 12/1/14?

        O believe me I’m not lol but since I’ve been clean for a year this one time use would be as if I’ve only have done it once and that it won’t store in my body like as if I were a chronic user. I’m also 26 years old if that helps.

      Is the first check 12 panel home test reliable? I tested myself Wednesday, 8 days after I did cocaine and the results came back negative (strong red lines across the board for both control and drug). And I called and asked if it tested for Benzoylecgonine. The threshold for the cocaine section is 300 nano grams/ml

      Reply
        1. Anthony

          If your under the 300ng threshold for Benzoylecgonine, are you also most likely under the threshold for Cocaethylene since it has a half life of 2.5 hrs which is much shorter then Benzoylecgonine with 6 hrs.

          OK thank you, so if I tested negative Wednesday on day 8 and I took another one this morning and tested negative again, is it smart for me to drink today ( 3 am would have been 12 days since last use). I haven’t drank since use over 12 days and I’m going to a football game and I still have off till December 1st. Do you believe it is unwise if I drink today?

            All I’ve been doing is drinking a gallon and a half of water a day and eating vegetables and fruits and blending vegetables and fruits in a 72oz blender and drinking that too. I would only drink today and then continue this regiment until my next test which could be any day after Dec 1.

    On Tuesday the 11 at 9:00pm, I smoked 60 dollars of some weak cut up crack with two beers. Done by 11pm. Someone told my boss on Tuesday the following week so on Tuesday at 4pm my boss has a guy waiting on me to take a suspicion of coke pee test. I am pretty sure it’s a dot grade test. I never expected it and never prepared. Do you have a percentage of pass or fail based on your experience. Should I be looking for another job or do I stand a chance of flying in under the radar.

        50/50 chance? I guess if they believe this guy then they may try a hair test in a week so they are going to get me one way or another. If I do pass. Guessing, maybe because I had the test at 5ish in the afternoon and has urinated several times during the day and an hour before I tested my chances will be better. If I get off of this I’m never doing it again. Lesson learned. I have too much at stake.

      Be very aggressive about cleaning your system. You still have time in hand. No alcohol, limit to tea and coffee. Avoid smoking as well. All these chemicals may hold back the drug in the body.

      Instead, your body needs plenty of fresh fruits and vegetables. Lots of water and physical activities.

      With all those steps, you are likely to pass.

      Adderal metabolism adds on to the overall liver burden. However, it’s unlikely to make a considerable delay in excretion.

      If you are a regular user of coke since months, it may be difficult to pass. However, if this usage of a one time event, you’re likely to pass by 20th October.

Since 10am on 10/22 I have been consuming a gallon of water/day, taking detox pills, stopped smoking, stopped consuming alcohol, started eating veggies/fruits, and very little fats at all.

    I have a test for a job I really want on 10/27. I am 35 yrs old, 6’3″, and 225lbs. I’ve consumed 1-2 times per year for past several years. Can you give me a percentage to pass based on your experience. ALSO, what can I do to boost my odds above what I’m doing.. Does drinking lemon juice work? What if I take a detox drink the day of? Are these detectible? I’ve heard they work.

    My sister is somewhat a regular user (although can you define what would qualify as regular as opposed to heavy or chronic) I believe and has binges as well as periods of abstaining from cocaine. She has a lot of chronic pain and as such, has been prescribed oxycodone and ms contin as well as gabapentin meds for nerve pain and cyclobenzaprine for muscles She has recently been asked to provide for a UA, which she has passed each time. She is somewhat active, very slim and very little body fat with a fast metabolism. She doesn’t drink but does smoke and drinks caffeine. Recently I have found out she has been using a lot since her last UA approx 2 months ago (not sure how much or how often or what quality) other than I know she used approx 5-6grams last week. she does not use any other drugs. She has to see her doc every 3 months for refills. I don’t know why she would risk losing her meds for being stupid but she has. How long will she need to abstain with aggressively following your suggestions for the metabolite to be below level of detection? And how much do the other meds interfere in the detox process?

    Hey Doc,

    So this past Saturday night I used cocaine, also had quite a bit of alcohol in my system over the course of about 9 hours. I used about 4-5 lines of cocaine and it was the first time in a long time. I am 6 feet and 185 pounds. I get over 30 minutes to an hour of exercise everyday, have never had any issues with my liver blood pressure or anything. I used until about 3 am Sunday, my drug test will be this coming Monday. This gives me about 9 days to prepare. I have been drinking water non stop, I am doing a 7 day rapid cleanse detox, eating regularly healthy and normal, the odd fast food meal, am drinking zero alcohol. I am so SO stressed about this friggen test as it could possibly revoke my offer of employment for a new job. I am peeing non stop and feel hopeful. Should I be worried, what are my chances?

      A very good oral hygiene, practiced on a daily basis. Plus, it’s better to start detoxifying the body whole for better results.

      Drink lots of water. Refrain from alcohol and limit to caffeine. Include plenty of fresh fruits and vegetables in your daily diet.

    I went on a 3 day coke binge probably snorting around 6 to 7 grams in that short period. I never used before though. My last intake was Thursday morning at 5 am and I have a drug test next Tuesday. Is that enough time for the coke to be out of my system so I can pass the test? That’s 12 days in between.

    Timeline of use:

    Used on the weekends for about 6 months prior to these dates. Then I did about a half gram on
    October 27th
    November 24th

      Ones using the drug on a regular basis since weeks, months or year. If it’s a weekly usage of the drug for more than 3 week, the user will qualify as being a chronic one. People taking more than this amount are definitely more difficult to treat.

        I am roughly 190 pounds, Male, late 20s, prescribed d-amphetamine salt combo 20mg twice daily. Done 2.8 grams stretched from Saturday, Monday, Wednesday. Alcohol intake was 4.2% beer which I consumed maybe a quarter to a half can each time (tallboy) late into the moment.

        I have a test coming up Monday possibly which is at random. I have started taking multivitamin men’s one a day(regular dose) , emergen C(1 packet), Nician(not exceeding 1500mg stretched throughout day) B12 Mcg, Vitamin E 1000 IU.

        Been avoiding caffeine, fats, and oils. Drinking tons of water. Sexually active and will be going to the gym Saturday & Sunday. Will incorporate cranberry juice & steamed vegis immediatly.

        First question is my prescription going to interfere with this detox and two do you think I will be fine. Stupid move on my part should’ve thought it through.

    Dr. I am 5’9 310lbs i have done cocaine every saturday for 2 Months i would be clean 6-7 days and then do some. During the 6-7 days i would just drink water no alcohol.

      you have good chances of passing the test. Drink plenty of water throughout the day. Exercising would be a good idea, as you sweat more and drink more water.

      Consume plenty of fruits and vegetables in your daily diet.

    Is it possible to pass a urine test after 19 days while drinking coffee and energy drinks every day. The test is in 3 days. Took home test and was clean with a solid negative test line. I have been drinking a gallon of water every day. No past usage did around a gram. I’m very worried it’s causing me some anxiety I have to pass this drug test. They are going to test me with a instant test cutoff 150 they won’t send it to the lab unless it comes up dirty. I can’t wait for this to be over I hope I pass and never be so stupid again to put everything at risk.

    All the info online is not reliable. Even after single usage, taking lots of remedies, cleansers, detoxs, vitamins, niacin, creatine, cranberry juice, cranberry pills, gatorade, water, zinc, magnesium, and more for 10 days, still failed the test (benzoylecgonine). I think constipation and other medications can also slow down the process. I have never tried the pectin method. Apparently, removing the metabolites from the fatty tissue and pushing toxins out of the stool is a method. It doesnt seem to matter. Maybe add sweating, steam rooms, exercise, long hot baths with epsom salt might help?? Also creatine is supposed to help because pH level is important on urine tests.

          I did one small line of cocaine on Saturday 4/7 at 10:30 pm. I am not a frequent user, the last time I had done it before that was 2 Weeks earlier. I had a few beers and a glass of whiskey after the 1 line. The next day Sunday 4/8 I drank some coffee and some water and just went about my day. The next day Monday 4/9 I sweat perfusely three different times of the day I biked with multiple layers on and I have a fast metabolism as it is. I drank tons of water and was peeing all day and night and ate fruits and vegetables and drank detoxifying drinks. I drank water up until about 3:30 AM on Tuesday 4/10. I went in at 6:30 AM that morning to take a urine test. This is for college sports drug testing so I do not know if they test for Benzoylecgonine in a urine sample? They said my pee was very diluted but that it just made the requirements for the pee sample. Do you think I can pass that urine test having only done 1 small line and going through all of that detoxing? Overall was about 32 hours from the one line to the test. But from what i have read since I did so little cocaine and did all of that detox and sweating and I have a fast metabolism at 6’ 170 pounds. Is it possible for me to pass the urine test? There is no way so little can be in my urine after all my efforts. Please let me know what you think!

    I have not used any mind altering substances since January but I was urine tested I passed the initial test but it was sent to the lab where they are saying I tested positive for cocaine. I don’t understand how this is possible. The only thing I can think is that I work at a gas station and handle money on a daily basis. I personally know 50% of our customers are active users.

    First off I am not a chronic user of any drug I work out 4-6 days a week. I’m 69 inches tall and weight from 160-165.
    Saturday got a little out of hand. I drank a bunch and took about 2-4 bumps up the nose of cocaine. Sunday and Monday I drank nothing but water. Don’t know exactly how much.

    Monday around 6pm I took 2 diuretic pills as well. Tuesday I woke up took my morning piss and got ready. On my way to work I took two more diuretic pills and drank a little bit more water before showing up to work.

    At 0710 I took my piss test. I used the last bit of my stream and it came out clear. I was still paranoid so I went to Walmart and bought a first check drug test. I came up negative for THC and cocaine. Cocaine line was pretty faint.

    Plus I know the cutoff level for cocaine is 300ng/ml for first check and I think DOD uses cutoff level of 150ng/ml for cocaine. Overall, I am 90% sure that I had 50-56 hours before my drug test

    So my question is, did I pass the DOD drug test or should I expect a positive results in a few weeks?

    Smoked maybe .3-.5 grams of crack cocaine since last night around 10:30p.m. (counting today it was a total of 4 small hits) I haven’t touched it but one other time a little over 6 months ago. Was smoked. I’m 5’10 and 190lbs. I get random mouth swabs once a week, possibly have one on Monday after 12p.m. at the earliest. Will I pass? I stay active and drink water. I wouldn’t say alot of water but I drink it. Any idea how long it will take to not show on a mouth swab and any tips to cleanse my system? Again it is a mouth swab that is sent to a lab and the earliest I would have it would be on this next coming monday.

      You have around two days with you. Keep drinking plenty of water. Abstain from all alcoholic beverages and smoking. Limit to tea and coffee. These chemicals hold the drug back in the body.

      Include fresh fruits and stewed vegetables in each meal. These serve as best detoxifiers. Maintain a good oral hygiene. Proper brushing, flossing and a lot of mouth rinsing to wash off all specks of the drug from it.

      You have good chances of passing a saliva test on Monday.

    I took about half a gram just under two weeks ago whilst drinking, about another half a gram over a week ago while drinking, then probably over half a gram 4 days ago after drinking a couple of beers (I stopped drinking when I knew I was gonna take it). Since then I haven’t touched alcohol, have been eating vegetables and stews, hardly any fatty foods and have been doing a fair amount of walking. I have drunk a couple of coffees and teas though. I could be tested anytime in the next week. What are my chances of passing?

          4 days may be inadequate. Cleanse yourself aggressively to give it a better chance.

    I’m sorry to keep asking questions but it’s really playing on my mind about getting tested.
    How many days would you say I’d probably be in the clear by?

    Thanks for all your help.
    It’s been 6 days now and I don’t see myself being randomly tested over the weekend so with any luck I should be fine.
    I will add I’m 6’2” and 175 lbs with good metabolism. Hopefully that helps my case should I be tested from today onwards.

    So it will be roughly 11 days since I last used cocaine now. I’m assuming if I get tested from any point onwards I should be ok?

    I was drinking with an old friend and after 4 beers did a small line of cocaine, est. @ 0.2 grams or less. I have not used cocaine or any illegal drug in 6 or 7 years. My work hair tests once yearly and randomly. I am 6′, 180lbs, drink lots of water, stay active, and take vitamins. Will this cause a positive result on a hair follicle test were it performed within the next 3 months? Could this be eliminated from my hair quicker?

      Your hair may show up the drug. Unfortunately, there’s no way of quicker cleansing.

      Hair grow and take up blood all the time .When your blood stream was carrying cocaine and its metabolites, some hair strands in your body may have nourished themselves with blood containing the drug. Those hair strands may give positive.

      Trimming your hair to the shortest possible length may help. Be cautious, they sometimes check body hair.

    It’s very interesting that when factual information is posted here regarding cocaine metabolite urine excretion and urinalysis rather than these nonsensical claims of 25-30 day or any other claim of detection beyond 5-7 days, it is not refuted or debated with any scientific fact or publication, but rather the post is deleted… Wonder why?

    Hello, I did one small line of coke, and haven’t used before. Will that show up in a hair test? Or will it be below the levels?

      Though, in most cases as yours, people pass. However, theoretically, the drug may show up. This test is very precise.

      Cleanse up flush out as much drug as possible from your body. Trimming your hair short helps in most cases.

    Hi, I did about .2 or maybe .25 of Coke at 11pm last night (Monday). I also drank 2 cocktails and did 1 shot. I haven’t done cocaine in 3 years, and I rarely drink (1st drink in over a year at least). I’m female, 5’10” and about 125-30 lbs. I exercise everyday ranging from 1 hour to 3 hours (intense cardio, running, circuit training, boxing). I have a drug test Friday afternoon. Will I pass? I’m worried I’m a poor metabolizer of the drug because i had an oral swab done by a doctor to do genetic testing on liver function and i tested poor for cocaine and some other substances
