How long does cocaine stay in your system?

How long does cocaine stay in your system?

Cocaine levels peak in the blood about 30 minutes after you take it.  But cocaine’s action in and on the body depends upon several factors. Dosage, mode of administration, single vs. multiple use. But in general, cocaine and its metabolites stay in the system and can be detected 2-4 days after use.

More on cocaine half life, peak levels, and drug testing for cocaine here. Please leave your questions or feedback about cocaine in your system in the comments section below.

What is cocaine used for?

When applied topically, cocaine can be used as a local anesthetic. Traditionally, coca leaves are chewed as a stimulant or brewed into a tea for refreshment and to relieve fatigue. Recreationally, cocaine is used to increase alertness, relieve fatigue, feel stronger and more decisive, can become highly addictive due to its intense euphoric effects (a strong feeling of well-being). Getting high on cocaine is possible because cocaine blocks the removal of the neurotransmitter dopamine in the brain. This result in an accumulation of dopamine that causes continuous pleasurable stimulation of brain cells.

Peak levels and half life of cocaine

The high you get on a single dose of cocaine depends upon how you take it. In general, the effects of an ingested dose of cocaine lasts about 20-30 minutes. Peak levels of cocaine in blood plasma also vary by mode of administration. When snorting cocaine, levels peak around 30 minutes. In comparison, oral administration of cocaine usually results in peak plasma concentrations at 1 hour. Single intravenous doses of cocaine produced an average peak plasma concentration within 5 minutes. Smoking cocaine base peaks at 45 minutes.

Intravenous = 5 min
Snorting cocaine = 30 minutes
Smoking cocaine base = 45 minutes
Oral cocaine = 60 minutes

The apparent half life for cocaine is short, roughly 1 hour. That means that the time required for cocaine levels to decrease by half in the body is somewhere around 60 minutes. However, with chronic use, cocaine accumulates in the body and resulting a prolonged terminal elimination phase for cocaine and its metabolites.

Cocaine drug testing

How long does cocaine stay in the body?  Drug tests called immunoassays aim to detect the main metabolite benzoylecgonine when testing for cocaine. Cocaine drug tests generally use a cut-off of 300 ng/mL to indicate positive use. Very low concentrations of cocaine may be detected in urine during the initial few hours after use. In general, cocaine metabolites like benzoylecgonine can be detected in urine 2–4 days after use for sporadic users and up to 12 days after use for chronic users or following a binge.

Still, another factor in the detection of cocaine in the system is mode of administration and doseage. For example, an intravenous dose of 20 mg cocaine can be detected for 1.5 days while street doses of cocaine (administered via different routes) can be detectable up to 1 week. Extremely high doses of cocaine can be found in the system up to 3 weeks after last use.

Still dose answer when smoking cocain in a cigar rite how long does it last

5:56 am November 30th, 2011

Hi Ray. If you’re asking how long does the high last when you smoke cocaine, the effects and blood levels of cocaine peaks at 45 minutes when you are smoking cocaine base. If you’re asking how long does cocaine stay in your system when you smoke it, it’s about the same for smoking as it is for snorting or oral ingestion. Small levels of cocaine or cocaine metabolites can stay in your system for days or weeks after you take.

How long have your been smoking cocaine?

And how much do you smoke?

Some time ago I lost my methadone script because when I was tested, the results showed that I had taken coke. I was really surprised as it must have been at least a month. I’m not too fond of ‘white’ and only used it once or twice a year. I don’t touch it at all now, it’s more trouble than it’s worth.

11:57 am July 8th, 2012

How long does it stay in your system if i just touched it for a sec with 1you finger?

5:50 pm July 9th, 2012

Hi Jay. If you touched cocaine, and did not snort, smoke, lick, or inject it…it never entered your system. So you don’t have to worry about detection.

I am not really what you would call a coke head, far from it. But I must confess that over the years I have kinda dabbled now and then.
My experience is only at street level, if that makes sense, but each time I score, it is utter crap, cut with bi’carb or any rubbish. Yea ! I can almost hear you saying, “If the stuff is so bad, why does he keep buying it”. and you are absolutely right, got no answer, suppose like most druggies, my brain’s not wired up right. What I can say without fear of contradiction, when I did enjoy ‘charlie’, it wasn’t like todays crap. It glisttened like the snow on the window sill on christmas morning and was as white. You knew it was ok by the return when you washed it. Now days it fizzes up like Alka Seltza coss it’s got a load of baking soda(bi-carbonate soda) cut into it.

11:56 pm July 12th, 2012

Hello Michael. I’d agree with you – there’s not way to check the quality of street cocaine unless you take a sample with you for lab analysis. Very dangerous!

9:58 am September 11th, 2012

hi i have a urientest on wensday n i had a very vey small hopt n i did that on monday nite wil i piss dirty on wensday?i never do crack i just tried it..

12:10 pm September 11th, 2012

Hi Shelly. Yes. It is possible that you test positive for cocaine use if you’re testing within 48 hours of use.

1:41 pm September 12th, 2012

I bit down on a dirty baggy and it had coke residue in it. I was given a test approximately 36 hours after. Would it still be in my system

10:03 pm September 18th, 2012

Hey how long does cocaine last in ur system and what can I do so it can go way

9:17 pm October 5th, 2012

Hey i did a 20 bag with freinds two weeks ago and havent done coc since is the trace of metabolites still in my system

1:45 pm October 6th, 2012

Hi Faye. Cocaine metabolites will stay in your hair for quite some time, until you cut it down short. Cocaine binges can be detected for 1-2-3 weeks after use depending on dosage. The best way to know whether or not cocaine is still present in your system would be to try an at home test for cocaine weekly until the test reads NEGATIVE.

8:36 pm October 12th, 2012

Ya I had a question I was drinking last Saturday night heavily and I did 2 normal key bumps at around midnight and had to take a drug test for work on Monday just wanted to know if it will come out

12:53 pm October 15th, 2012

Hi Josh. It’s possible that your drug use is within the 2-4 day detection window for a cocaine urinalysis test. You’ll have to wait for the results to know for sure whether you’ve passed, or not, but it’s possible that Saturday night’s use is detected.

4:16 pm October 15th, 2012

I detect from some of the posts here, no one is hard core coke heads. taking that into account, you shouldn’t have a build up in your system and with any kind of luck, you may be ok.
Depending on your situation with whoever is testing you, and if you are more or less sure you will test positive, maybe you could tell them that you used and how you regret doing it. Like I say, depending on who is doing the test and why. If you are going for a job interview and you know they will test you for coke or smack, the best thing you can do is call in sick, fake a bad dose the flu.
Whatever way you decide to go, good luck and I hope that these tests put you off hard drugs.

2:32 pm October 16th, 2012

My question is if my last use of crack was saturday at 1:30 in the morning will I pass a urine drug screen on monday at 7:00pm.

5:10 am October 17th, 2012

Hi Dee. Your drug use is within the detection window for cocaine…so it’s difficult to predict whether or not the drug screen will test dirty. Maybe yes, maybe no.

11:16 pm October 21st, 2012

i need help quiting

7:08 am October 22nd, 2012

Hi Carlos. Thanks for reaching out for help. You can call the 24 hour national drug hotline at 1-800-662-HELP. This is a free government service which is sponsored by the Substance Abuse and Mental Health Services Administration. They can refer you to the next steps you can take to get clean. There is also a National Cocaine Hotline at 1-800-COCAINE.

You may want to think about going to a medical detox and then rehab. Psychotherapy also works quite well to address the underlying issues which compel someone to use cocaine over and over again. And remember: you are not alone! There are thousands of people in the same boat, and many who have gotten better!

4:11 pm October 23rd, 2012

Hi, A friend of mine (really!)… used some cocaine three weeks ago;
(one line and an end of a Mini Spoon). He now has to go for a medical for a new job in a weeks time. He is terrified. (he NEVER uses any drugs and this was something that just happened). what can be detected??

Thank you in advance.

7:41 am October 24th, 2012

Hello MaXxX. Most medical exams use urinalysis or blood tests to detect RECENT drug use. Hair samples are often ordered by drug courts or opiate/opioid-prescribing doctors when long-term detection of certain drugs is important. In the case of a urine or blood test, your friend’s cocaine use will highly probably go undetected. Too much time (one month!) has passed between use and screening for cocaine metabolites to be present in measurable amounts. On the other hand, even one time use of cocaine can be detected in a hair sample taken one months after use.

Does this information help?

4:37 am October 27th, 2012

I take some on monday late in the night like 3:00am of tuesday it wasnt that much but i have test on tuesday in the morning ( one week later) . I’ve running and drinking much water even has a 7 day product to clean my system. Do I test positive?

3:59 pm October 30th, 2012

I smoked crack once, then shot it once all last night. I hadn’t touched that stuff in almost a year. I have a possible drug test coming up on Thursday morning. It was one in the morning last night when I did the last little bit. I was wondering if there’s anything I could do to pass the test say like drinking a whole bunch of water and possibly get ready clean?(which is a detoxify drink)

Hey i used cocaine about 2 weeks ago and ima get drug tested(blood samples) in 2 weeks or less will it show up? I made a dumb call and snorted 2 small lines, i never do it juss that time. pls give me info im really scared my life depends on this test!

8:20 am November 5th, 2012

Hi prince m. Thanks for your question.

Blood tests for cocaine use are mostly used to test for current use. The detection period for cocaine blood tests is really short and is generally less than one (1) day after use. Some blood tests for cocaine cannot even detect cocaine use eight (8) hours after use. So waiting for 2-3 weeks before testing for cocaine in the blood should result in a NEGATIVE test result.

11:26 pm November 11th, 2012

so i have been shooting cocaine and heroin approximatly 2 bags each a day for the past week and a half. i have a drug test on thursday it is sunday today havent used since yesterday afternoon. if i have used close to everyday for over a week or so but i dont use for 5 days will i pass a 5pannel urine test?

2:27 pm February 13th, 2013

Hello helpless. I’d suggest that you call Al-Anon and go to a support group meeting. Also, call 1-800-662-HELP, the national drug use hotline for support and more answers. You are not alone!

8:46 am February 27th, 2013

Well I took 3.5 grams last Saturday late night (Sunday) and I passed drug test today (Tuesday)

6:47 am February 28th, 2013

I did 3 lines on Monday night and I have a drug test the next Monday so 1 week. what should i think?

6:41 pm February 28th, 2013

@ Joe Is it a urine,blood,saliva or hair test? If it is blood or urine test your safe but a hair strand test will show you’ve used for over 1 year. Also it depends if you’re an occasional, regular or chronic user. Many people don’t realize it isn’t the actual drug that laboratories test for. They look for the Benzoylecgonine in which is a metabolite that your body makes when doing cocaine. Depending on liver and kidney function, cocaine metabolites are detectable in urine. Benzoylecgonine can be detected in urine within four hours after cocaine intake and remains detectable in concentrations greater than 150 ng/mL typically for up to eight days after cocaine is used. I have used in the past and did a urine test 3 days later and passed. Increase water intake and pee a lot it should help you pass. If you can afford it go and get your own drug test at a smoke shop and see if you will pass. Then you will know if you are already clean that is what I did and that is how I knew after 3 days I was clean. Hope this helps

4:56 am March 25th, 2013

my close friend snorts about a gram of coke every other week, she used about a gram 60 hours prior to a mouth swab test. should she pass or fail?

12:48 am March 26th, 2013

@ Greg A saliva test will show a positive result within the day of use up to 5 days. I have yet to be given a saliva drug test but I’ve had urine tests. The nurse that took my urine sample told me that urine tests are typically of the same detection time of 3 to 5 days. 5 days is more for chronic users. Your friend is still within the window of detection but will likely be a NEGATIVE result being that 72 hours is 3 days. Hope this helps.

1:57 am March 27th, 2013

i did a 20 sack of cocaine on Friday afternoon, got busted by cops on Saturday, was givin a blood test at 7:30 on Saturday nite, will I fail?

6:02 pm March 28th, 2013

@ Worried The detection time in blood is usually less than one day.

4:21 pm April 3rd, 2013

Hi everyone my sister was at one point in time addicted to Crack Cocaine and she got better without going to rehab or anything like that she worked really hard though. As long as you work hard you dont really need any ones help I learned that from my sister it is really hard to do it, but never ever give up. It is worth it to get off of this drug.

Hi took coke three weeks ago I have a drus test tomorrow will I pat how long will take get out my system

10:45 pm June 28th, 2013

hey,i used a gram of coke on Thursday night(snorted betwenn 3 people)I have a pee test the following Friday,,,will I be clean???

9:25 pm July 1st, 2013

,@Ralph You should pass as it was a very small amount that you had. I know that it takes 3 days to a maximum of 5 days but for chronic users it can take longer. If you drink plenty of fluids and urinate a lot you have a better chance of getting it out of your system quicker. When I used in the past I bought an at home test and passed at barely 3 days clean. I also used quite a lot more than you on a regular basis when I took my actual test. Good luck!

9:16 am July 7th, 2013

Hello, I did roughly a line of coke (maybe a little bit more (it would have been 2 at the most) on saturday around 9-930pm. How long would that take to flush from my system? I drank quite a lot of water throughout the night and am continuing to do so today. I am worried that if i got a drug test done i would fail, are there anyways to help me speed up the flushing process?

9:38 am July 7th, 2013

Oh also take prescribed tramadol hydrochloride, although not recently could this help mask the cocaine? I am very worried as if i failed a test it would completely mess things up for me at the moment…

7:23 pm July 17th, 2013

I used 1g of cocaine on a Friday, 12 days later I had a urine test, it is possible that I get caught?

9:50 pm July 20th, 2013

@ Hanson If I understood right you have a test in 12 days? If you have a regular urine test you will pass so long as you don’t use anymore. The window of time for detection in urine is usually 3-5 days depending on whether you are an occasional user or chronic user . If it was a hair strand test you would positively fail but since it’s a urine test you’ll be fine! Good luck

8:05 pm July 22nd, 2013

@ Cris that made ​​the drug test 12 days after using 1g of cocaine, and the test is urine, and after chronic User is one who uses one every day or once a week?

4:44 pm July 24th, 2013

hi.. im on probation and slipped up I was on crack real bad for yrs but workin hard to get clean, I slipped the other nite and used I have a drug test in 12 days if its positive im goin to jail HELP how do I pass?? what can I do??

8:03 pm July 24th, 2013

I’m not here to judge anyone because I don’t know you. But I do know the effects of crack on a family. My husband has struggled with a crack addiction for a little over 10 years. He got addicted immediately. He has never had to face legal consequences, but the financial, relational, and emotional consequences have been devastating at times. For those of you who are concerned about whether or not you’ll pass a drug test based on amount of cocaine used, how long ago, your weight, etc, I encourage you to be more concerned about how your usage (and likely addiction) will affect you long term. That stuff messes you up and will lead you to destruction. Please get help to stop using, for you and for the people who love you and care about you.

7:26 am July 30th, 2013

@ Hanson Sorry for the delay in responding to your question.

A chronic user uses daily, everyday. A casual user is probably 1 time per week or less. Although, using 1 time per week isn’t a chronic user it is considered to be a regular user. Of course though, you know you must stay clean with absolutely no using until after the test. Or better yet,not ever using again! Easier said than done,right?! Anyway I’m here for support if you need me. Good luck I hope this gets to you in time!

7:36 am July 30th, 2013

@ Madea If it is a urine test, you do not use anymore from today until test day, you will pass. It takes 3-5 days to pee clean. Anything beyond the 5 days is for chronic users. You can read my previous and other posts on here for more tips. Good luck!

12:40 am September 17th, 2013

I did cocaine for 10 years and spent 200 a week I went for a drug test for a job and have been clean for 80 days at the time of the test .do you think I will pass the urine test?i haven’t heard back from them in a long does it take to become completely clean?any help would be greatly appreciated..

4:34 am October 4th, 2013

Hi I just barely got probation for 4years..I get tested on the 20th of next month and were the 21st today..if I do a 20 of cocaine will it come out on my probation piss test ?? Please help I am concerned about this issue..

5:26 am November 23rd, 2013

Dianne… You will be fine

8:15 pm December 3rd, 2013

@Martin I know this post is really late but I just got it now. You will be fine if it is a urine test. It takes 3-5 days normally to pee clean. I know it’s a hard habit. to quit but maybe lay off the stuff until your off probation because you never know when your probation officer may spring a surprise urine test. I have no idea where you’re from but where I live they can randomly make you come in and do one. Good Luck!!

@J bird Yes, you should pass since it will be the 6th day clean and usually it takes 3 -5 days to pee clean. In the past when I used I’d pee clean by the 3rd day.

Hello there, I was curious about a drug testing coming up recently and wanted to know if a person drinks lot and lots of water plus also using a prescription fluid removal pill 48 hours before the actual drug test..Would they pass the test ?.This person was using $100.00 worth of crack cocaine prior and nothing else. Thank You, Susan R.

11:04 pm May 23rd, 2014

Hi there, I havent used cocaine or had any alcohol for almost two weeks. Last night I had 5 lines and 8 drinks. I have test on Monday. I train eat well drink alot of water I weight 82kgs lean. Will tge cocaine be in my system?

9:09 pm May 24th, 2014

Hello Susan,
What kind of drug test is it? If it is a simple urine test, it can takes anywhere between 3-5 days to pee clean. Do you mean that the person smoked $100.00 daily or just the one time previous to this post? It can take longer for chronic users but if you are an otherwise healthy individual and only an occasional user 3-5 days is usually the window of detection. Drinking water most definitely helps get the drug out of your system quicker. The fluid removal pill is a VERY bad idea as it causes false positives. Water and time are the only answer. So,my advise is to simply drink plenty of water and pee a lot. Of course, don’t drink too much water people can die from overdoing it with the water. In my experience there are no special pills or drinks that help pass a drug test even though these products promise to help they simply don’t. Good luck!

7:56 pm June 17th, 2014

I’ve been taking about a gram of cocaine most days this past 3 weeks,I have to go to my doctor for a routine blood test soon and was wondering how long cocaine would be detectable in my blood?

5:20 am June 23rd, 2014

I would like to quit using cocaine

2:01 pm July 2nd, 2014

Experimented with some lines for no longer than a month about 9 months ago. I have to say it was the stupidest thing I have ever done, no problematic reasons to turn to cocaine, but I became aware of its effects during the process of experimentation including the highs and immediate lows, the drug business (why would you want to exchange the sanity of your life and not to mention how it affects or costs the lives of other people in your circle to some drug dealer in the supply chain to make money off your misery) and the potency of its addiction. Those who do it for the highs and the sense of well-being, it’s all psychological and it can be achieved through other ways and one more thing i got to say is that most things in life are solid and they decay over time all there is left are the gestures and impressions left behind. What is yours?

1:09 am July 8th, 2014

I have used for a year and a half and have a huge tolerance. I last used at 10pm, July 4th. I have a drug test for a new job that has to be done by noon tomorrow. I took a 40.00 home test an hour ago and it came back negative. Should i believe that test?

6:23 am July 28th, 2014

I had used it hard core for the last 10 years can’t feel no side effects apart from making me smoking lots of cigarettes that I hate it when I start smoking and maybe I don’t realise side effects much but all depends on quality maybe! I just started to feel paranoid when using it but feeling okay when I’m off of it I feel normal maybe next day at the most I feel bit agresive but I know where is coming from so I’m in control of my self

1:34 am August 17th, 2014


4:21 am August 19th, 2014

Today is Monday. Not last Saturday but the Saturday before last I snorted a very small line of coke. I’ve been paranoid ever since so I went and purchase a urine test and the result was negative last Sat. ( one week later from date of use). Today I got randomed for a saliva test….my question; is it possible to test negative on one type of test and positive on saliva???

10:00 pm August 19th, 2014

My son is trying to kick coke and heroin at the same time. He shoots both. Can he do this sawfly and what can I do to get him through this. He has suboxson but he says he can not use it because he has coke in him.

9:49 pm August 22nd, 2014

Hi people who ever has a drug addiction problem please remember that no medication will help you guys get of the drug. Methadone is a drug itself, by taking methadone it simply means you are substituting a drug for another drug. In other words it’s called cross addiction. And remember there is no cure for addiction, addiction is something that you have to live with for the rest if your life, especially those that are on the drugs and don’t get immediate help.

So please seek help asap before it is too late.

I am planning on travelling overseas where upon departure I may be subjected to drug screening. It is possible I will be using small quantities of cocaine orally, Any idea of how they test for drug use and how long before should I stop before leaving the country? Thanks guys!

8:10 pm December 9th, 2014

We’re desperate. My ex-husband uses cocaine. He has Diabetes and doesn’t properly follow treatment. He has been “found out” by his family and doctors and now wants to “be left alone and die alone.” His eyesight is poor; his health is obviously dangeeously poor. Looks like he’s hit rock bottom. Our young adult child is scared for the dad’s life. Is there anything we can do for ex-husband? (I’m recommending to our child to look into getting into therapy to help cope with this). Any suggestions will be appreciated.

3:20 pm December 10th, 2014

ok so I snorted about a gram of very strong coke last Thursday . It is now the following Wednesday . Can I pass a urine test today at lunch ? Or is that what is considered a binge and can stay in my system for up to 10 days ?

6:13 pm December 11th, 2014

Hi Kerry. Isn’t there anyone that can be there by your side? You need care, fluids, and food. Have you seen a doctor? It’s also smart to search for NA meetings or other counseling sessions in your area, after you get physically better.

6:55 pm December 13th, 2014

Hey, i shared a little less than a gram of cocaine with 2 other people last saturday December 6th. I snorted about 3 small lines. I have a drug test monday, will it show?

10:08 pm December 18th, 2014

I’m an idiot. Succumbed to “Try it!” to the tune of 2 lines at a conference last Monday, totally forgetting I have to test for workers compensation. In a common pain mgmt docs’ test, does a 200 lb 6′ guy who regularly works out and consumes a lot of water while drinking moderately (1-3 servings daily, I broker wine) fall in that 2-4 day demo? And is there a home drug test you recommend? Thanks so much for what you do here. I’ve never looked into any of this stuff before and it seems like you help a lot of people. Please let me know if there’s any way I can donate/support.

10:29 am December 23rd, 2014

Hey I was drinking Friday night and did two keys bump on midnight for my first time. That coming Monday night did a swap test. Is it possible that it will show?


2:11 pm December 23rd, 2014

Hello Jim. Depends on the test. If it’s a regular urine drug test, you’ll be fine. In general, cocaine and its metabolites stay in the system and can be detected 2-4 days after use. Seems like enough time has passed by now. You can go into the pharmacy section in a supermarket and gt a home drug test.

5:11 am January 7th, 2015

Over a four day bindge which lasted from miday Friday to late Monday night. I smoke maybe about a quarter ounce of is Tuesday of the following week and I have not smoked in & days. Have a drug test tomorrow. is the crack out my system. someone experienced please reply. It will be * total days.

1:59 am January 16th, 2015

I have a question…. my sister does alot of bad stuff, stuff we don’t agree with but the things she does makes it so she can support her kids :(
It’s only her and I as we have no family… she works 2 jobs and goes to school full time, she’s had 6 surgeries all of which has left her on percocet for 10 years and she’s only 25…

My question is, she has a drug test coming up for her Dr app to get her script, just yesterday she touched heroin SHE DOES NOT USE, can this seep threw her skin, can she test posture for heroin on a drug test if she only touched it? She’s freaking out because someone told her that it seeps threw the skin….

12:12 pm January 16th, 2015

Hi Nina. Your sister has nothing to worry about. Heroin absolutely cannot enter your organism by just a touch.

I have never use coke a day in my life but I can’t seem to stop catching dirty coke urine. I find it very amusing that “licesned” technicians don’t seem to know this. My question is from touching it, how long will I be dirty?

what about breastfeeding and coke? Can a nursing mom party with of lines or not? Thanks

3:38 am February 9th, 2015

How long does coke take to get out of your system after regular use through say a 3-6 months steady. Intakeing aproximately a gram a week?

12:31 pm February 9th, 2015

Hello Elisa. Because of cocain’s chemical nature, high concentrations of cocaine are expected in milk. Be especially careful if your baby’s a newborn, since a newborn has not yet developed the enzyme that inactivates cocaine and serious adverse reactions can follow. After taking a single dose of cocaine it can be present in breast milk, and transfered to your baby’s organism for up to 36 hours. So, if you do choose to party, don’t breastfeed for about 36 hours. Of course, it would be best if you don’t do coke at all while breastfeeding.

9:57 pm February 10th, 2015

Hey im freaking out because I did cocaine sunday at about 2 am and I had a urine test today (which is Tuesday) will i come out positive for cocaine p.s i only took one hit and that’s it very little

12:50 am February 11th, 2015

Thank you so very much! Is definitely not worth it, I appreciate your information, I will wait for a better time to party! I would never put in risk the life of my little one.

11:20 am February 11th, 2015

Glad we could help, Elisa. Feel free to contact us again if you have any other questions. Have a blast and enjoy motherhood!

7:16 pm February 11th, 2015

i did 2 lines of cocaine last night .. And had a random drug test the next day at work will it show up in urine for the drug test ?

9:10 am February 12th, 2015

I think that this is not well known but I’ve done some reading to confirm this. Cocaine is very hard on the kidneys and can cause kidney failure. Within hours of use i had pain in my kidney the next morning, the dr confirmed a kidney infection. I said nothing of the coke. 3 & 4 days later later i used again and within hrs was in pain again. When i returned to the ER this time i was honest. So they did extra tests and told me of the severe risk of kidney failure and likely the infection want clearing up because i was using and stressing my kidneys.

6:39 pm February 12th, 2015

If an individual does 3 key bumps on a Friday night/sat morning around 230am, will it show up on a urinalysis on Tuesday at 1030am? Saturday was a half water, half beer day, in bed around 3am Sunday. Water consumption was adequate two days being Sunday and Monday accompanied with at least 2 vitamin drinks those days. Monday involved an hour workout session with 20 mins of steady cardio. 2-3 days?

6:41 am February 15th, 2015

The last time I snorted cocaine was today around 4 am I have to take a drug test Monday at 11:30am I would like to know if I would be clean for that test if drink a lot of water

I just got out of jail I did 8 days got out nd smoked gram nd half of crack I am 115 lbs I am 5 feet 2 inches how long do u think until Its out of my body I have test on Thursday????

6:15 pm February 18th, 2015

If you used less than a gram on a Saturday and was tested on a Tuesday and you don’t use regularly will it show up on a test?

4:59 pm February 19th, 2015

Hi thanks in advance for your help!
I haven done any coke in past 15 months, I did a very very small line of very high quality coke on sunday night(around 11:30pm) & I have a urine test at 12:30pm on Saturday & I’m worry if I will be clean or no?
I started drinking a lot of water since Wednesday morning, yes it will be almost 6 days and i saw I should be clean in 3-5 days but I’m thinking what if some coke left in my nose for a day or two after snorting! Will it effect on those 3-5 days ? I also snort Opana every day and would those opana that gel up a little would hold some coke in it after I snort the line of coke ? These are what make me worry about being clean on the day of my urine test! I had snorted some Opana before taking the coke & I didnt blow/clean my nose until late monday so does that mean I still had some coke up in my nose and when exactly that 3-5 days start from ? Thank & please let me know your opinion. Thank you.

5:05 pm February 19th, 2015

Hi Donzell
It’s possible that your drug use is within the 2-4 day detection window for a cocaine urinalysis test. You’ll have to wait for the results to know for sure whether you’ve passed, or not, but it’s possible that Saturday night’s use is detected

6:00 am February 22nd, 2015

FYI I just thought about everyones asking how long will it take to clean my body pr this drug takes 3 days that drug takes 4 days to leave your system and on & on, I think these are all base on a normal person with a normal daily diet like eating 3-4 meals per day drink 8 glasses of water and enough fruits and Vitamins so if u did couple of lines and having a test in 5-6 days lets say you dont drink not even 2 glasses of water or one meal a day basically having a bad diet like me then it will take you a lot longer to become clean I guess, Its my opinion. Good luck

4:35 pm February 23rd, 2015

last time i used it was saturday (2 days ago) and on friday (in four days) i am getting tested for it via blood. will it show up?

When a person does what is called a ‘bump’ up their nose, how long does it stay in their system? (Cocaine)

3:06 pm April 20th, 2015

Hi Karol. No matter how cocaine is administered, it goes into the blood and through the blood to the brain. The various modes of administration only provide you with a different time period for the onset of effects. Still, the drug will be broken down and metabolized by the body before it’s eliminated. And drug testing labs don’t actually test for the drug itself, but for it’s metabolites. So, I’d say that the detection window of 2-4 days for a single time use is a realistic estimate. In habitual and frequent users, cocaine metabolites can be detected through drug tests for a month.

3:19 am May 2nd, 2015

Hey, I have a fairly important question.. I’m in a methadone program, and they recently started testing for cocaine. My question is, I’m not expecting a test for 12 days. I don’t use often, I used to use fairly often but I quit when they began testing and penalizing for positive tests. I’ve apparently done about 2 lines, less than 1/4 gram altogether in a drunken blackout, came to about an hour ago and was told about this. I’m afraid I’ll lose another carry, will it still be detectable in my urine after 12 days?

4:37 am May 3rd, 2015
