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.

        I am an occasional, but not a frequent or regular user. This October was an exception and last time in August or September one time with a larger amount but nothing crazy. Otherwise, before August and September, it would have been a very long time l. I sometimes make bad decisions. The week of October 4th, I did two bumps on two occasions, two different nights. I did a larger amount on the night of October 13 after heavy drinking and probably has two or three more drinks will doing it. I continued to drink October 14-16. From 17-20, I only had 1.5 glasses of wine combined on Monday, otherwise totally sober during these 4 days. Then started drinking again until the test on 26th. All together 12.5 days from last use, heavier drinking during these 12.5 days with exception of 4 or 5 nights. Drink plenty of water on daily bases. I have bad diet, I am 5.10 and weight 270 pound so super overweight and in early 40s. I also
        am on two prescriptions for Wellbutrin and adderall. Will I pass a urine test for cocaine? I know I will positive for adderall, but that’s okay.

    I have to say, clearly a lot of people depend on your advice and it brings them comfort. Myself included.
    So, thank you for all the work that is put in here. I appreciate it and I’m sure many others do too.

    People make stupid mistakes and don’t think about the consequences. I could potentially destroy my career with a couple of lines on a night out. Cocaine is so overrated, it never really improves my enjoyment of a night, I end up doing the classic more more more thing and it costs too much.

    I need to learn, and I reckon (by the amount of posts here) a lot of others do too, if you have something to lose then think about the consequences and don’t do it.

    I really am kicking myself for being such an idiot.

    Anyway, thank you for your advice.

    Athlete with possible testing in about a month and a half. Drank about 10beers and very stupidly decided a bump on a key was a good call. Didn’t feel any effect and actually fell asleep within an hour of it. One-time use/last use was end of March and consisted of probably just under .25g but again with heavy alcohol

    I’m assuming I’m being overly paranoid but should I be worried about the metabolite by the end of August? Obviously complete abstinence from today onwards.

    Hi Doctor. I may be up for a random on Thursday. Over the past month (on 4 separate occasions) I may have done between .75 gram – 1 grams. I have been drinking alcohol for roughly half of days out of the month, as I was unaware that it delayed the cleaning process until now. I am in good health, weight 165 lbs, in my early 30’s. I have been going to the gym roughly 2 days out of the week and drink a decent amount of water. By the time I may test, the last occasion would have been 18.5 days. What are my odds of passing this test if I’m selected?

        Thank you for your reply. I have a little bit more information for accuracy sake (learned a lot reading this site). The test is for Benzoylecgonine with initial test cutoff of 150 ng/mL and confirmation at 100 ng/mL. I have partaken, with small amounts as I described above, off and on throughout the year. Also have had been taking caffeine on a regular basis during this time (I’ve only been able to clean out part of yesterday and today before possible random tomorrow). Do you still believe my chances are good?

    Hi,

    I stupidly did a gram or a bit more while quite drunk last Thursday night and into Friday morning. I finished up at 6.00 am on Friday morning.

    Now I have found out I need to do a medical with a drug screen on Wednesday (tomorrow) at 3.30 pm.

    I’ve drank loads of water since Friday, no more alcohol, coffee, tea or other crap. I’ve eaten reasonably well to and done some serious exercise.

    I wouldn’t be a regular user but have used very infrequently before but not in a number of years at least.

    Have I any chance of passing. It will be roughly 130 hours since my last hit by the time of the test. It’s a urine sample I think.

    Need help please.

    I’m a chronic pain patient currently prescribed norco and Xanax, also non narcotics. I’m in pain management and have a very extensive urine drug screen coming up that checks for all metabolites. After having 2 glasses of wine and a shot of alcohol after a night out, I stupidly was persuaded into snorting a half a line of cocaine. I regretted it instantly and can’t stop crying. I’ll never do it again and I’m so scared I’ve ruined my life. August 5th was when I had consumed the alcohol and cocaine, my test will be in 12 days or less. I’m 5’6 140 lbs, lightly active only a couple days a week. Went to a sauna today and trying to keep drinking water

        Since all these medicines get metabolized in the liver, drug excretion may slightly delay with these medications. However, this delay is not much.

    Hola!

    I had a random hair test yesterday 8/28/18. It is a Phychmedics 5 Panel Test. I did .2 grams (2 lines from a $20) of cocaine with some alcohol in my system on 5/2/18. Prior to this i had a few key bumps mid-March & a few lines on NYE 12/31/17. This makes me 118 days clean when sample was taken. I cut my hair to 3/4″ at the 60 day mark and cleaned it up to about 1″-1 1/2″ around the 90 day mark. I had also done various methods in-between that had some success stories (macujo, bleaching, etc.). I stopped trying to “clean it up” around the 70 day mark because some of that stuff just doesn’t belong in your hair haha.

    The sample(s) they took yesterday were about 1″ to 1 3/4″ long as my haircut in that spot is different lengths.

    I’m 5’10”, 170 pounds, dark brown hair & a fast metabolism. Active from work to sports but do enjoy a few beers with buds every so often.

    I am prescribed to multiple pills for pain management but only use Tramadol here & then. I also had some Penicillin about a month back for strep throat.

    I feel like I’m in the clear (hopefully) but would like your opinion please?

    Will update when I receive results!

    Hi,
    Stupidly, I snorted a line of cocaine on a Saturday evening around 10pm, consumed with 2 bottles of lager in the same night. From the morning after, I trained every day since, sweating buckets, eaten healthily, drank loads of water, no further alcohol or cocaine. My last use before this was approx. a year ago.
    I had a urine drug test for pre-employment on the Thursday afternoon following the Saturday, so roughly 5 days later, I drank loads of water before the test on the day too. I had a migraine the night before so I’d consumed 4 Paracetomal/Codeine tablets and an Ibuprofen in the 18 hours leading up to test. The test came back 24 hours later as ‘inconclusive’ and has been sent to the lab for further analysis. What do you think this could mean? Are they testing further for drugs? Do you think the cocaine/benzoylecgnonine would have shown as positive in the initial test if it was still present? Thanks for your help.

          It’s unlikely for cocaine to show up after 5 days of cleansing, in your case.

      Only water is sufficient. Fasting is not required .You may take normal food, preferably containing plenty of fruits and stewed vegetables to aid detoxification of the drug in the liver.

      Likely to be clean in 3 to 4 days.

    I’ve snorted between 1.5g and 2g in the last week. Before last use was a little over a month ago. I’m 5’3 & 143lbs. Not the best eating habits lately, and minimal alcohol use with and in between. Possible UA the 13th or 15th it’s morning of the 9th ( used last .5 last night into this morning) …. pass?

    Hey Buddy,

    I did approximately 2 key bumps of coke while on vacation while consuming a lot of alcohol. I haven’t done coke in 10 years prior. Currently, it’s been approximately 16 days from the time of consumed the cocaine. I have not had alcohol and have been drinking a gallon of water a day since then. If I had to take a urinalysis in another week, 23 days, would I pass???

    I been using pretty regularly on weekends for about a little less than 6 months. Started light- maybe .5 gram a week for first couple months, then I gram a week. Now for past couple months it’s usually ~ 2 day binge of ~ 1-2 grams. It’s fairly low grade, prob cut several times- if that matters. Last use was an excessive binge over the holiday of ~ 3 grams that started 11/23 ended evening 11/27. I drank lots of water, but did have a couple glasses of red wine evening of 12/3- although that’s the first drink I’ve had in almost a year- if that lapse even matters. My diet is reasonable but metabolism is not great due to hypothyroid… and I’m not overly active. I’m overweight at 5’7- 180lbs. I also take rx clonazepam 1mg (not mixed w come, but on off days- if that matters) …this is sounding worse and worse as I’m writing it. I didn’t realize that if I used often, the elimination timeframe expanded- nor was I expecting to be drug tested. At this point, I’m DONE- this whole thing is a ridiculous situation to put myself in and makes me realize it’s def not worth this stress!! … but that doesn’t change what I’ve already done. To the point- I completed the 9 panel Drug screen on the 7th Around noon. Do I have ANY chance of passing this (Other than the clonazepam that I provided the RX for…) or do I just try to salvage my reputation and resign??
    Thoughts please!!

    How many days would it take to pass a saliva test having done 3 lines of cocaine mixed with lots of alcohol? I’m 35, 6’0 feet tall and 180 pounds. I drink plenty of water and eat healthy food. Haven’t drink alcohol nor caffeine since then but don’t exercise a lot. It was the first time I tried it and the last one. The test has a cut of 20ng/ml and I’m really concerned because I understand cocaethylene takes a really long time to get it completely out of your system. Thanks

I have a urine test 1/14. I’m not consuming anymore alcohol or drugs before then, I drink a minimum of a gallon of water a day, I drink herbal detox teas, cranberry juice, and make two cups of hot lemon water daily ( full lemons ).

      Since the passing out levels at low, it’s difficult to assure you about the results. However, one time users are usually quick at cleansing themselves. Would also depend upon your basal metabolic rate and present activity levels.

    Im 5’8″ tall, 145 lbs, and generally have a fast metabolism. I have been doing .5g-.75g cocaine on the weekends for the last 2 months, along with drinking heavily on weekends, the most recent line I took was 6am sat morning. I have a urine test on thursday. I could delay this until monday. Does it flush out of your system weekly? Or does continuous weekend use make the enzymes build in your system? Chances of passing?

      Since you’re a regular user of the drug, it needs more time to clear out the drug. Weekly usage builds up the drug stock in our body, making clearance more difficult.

      Since you’re using marijuana, your liver may take more time to clear out all other drugs as well. So, cocaine clearance may be slower than expected.

      However, one time use goes is your favor. More likely to pass a urine test for cocaine.

    Hi,
    I was drinking on the night of the 5th and stopped at 2 am on the 6th. At around 4am I did one line of coke but then remembered I had a drug test coming up so started drinking lots of water. I also ordered a lot of home drug tests but they don’t detect cocaethylene i guess. I tested negative on the home test at hour 50. It has been 6 days now that I’ve been going on walks and drinking lots of water. I am 6,1″ 190 lbs. In fairly good shape. I also eat healthy. I have not had a sip of alcohol since then.

He has struggled with substance abuse problems in the past including marijuana, alcohol and cocaine, but he functions. He uses vitamins, drinks lots of water. His diet is moderately healthy eating at least a couple vegetables or fruits each day. He past a urinalysis drug screen with two weeks notice in about December 2020.

    Hello,

    Please can you help?

    I have been taking cocaine weekly (around 0.6) for the past few months (with around 2/3 weekends off) and drinking heavily when taking/not taking. The last time I took was a 2 day binge on the 15th and 16th September, having about 1 gram. I have a pre-employment drug test on the 3rd October with a cut off of 150ng for screening and 100ng for confirmation.

    I have been cleansing since my last binge (16th sept), drinking about 3L water a day, lots of fruit and veg, exercising daily and only a sporadic drink twice. Is there anything else I can do to help detox?

    What is the likely hood of me passing this pre-employment drug test?

      Bze is a metabolite of cocaine. So, it’s concentration would increase simultaneously with decrease in levels of cocaine. Rise in levels is usually very sharp.
