Cocaine can remain in your hair follicles for up to 90 days or longer, depending on how much you had and how frequent your use was. So it would not be uncommon for it to show up 4 months after using it if your body has a difficult time detoxing itself.

If you are expecting any other surprise tests, then I would highly recommend doing some sort of total body cleanse or fasting for a number of days on just water, in order to help your body heal itself.

I hope this helps!

Cocaine metabolites can linger in your hair for a very long time, so there is a chance that it was caused by your prior use, even if it was months ago. This is especially true if you have longer hair, or use gentle shampoos and etc.

Otherwise, there are several things that can cause false positives and it would be easier if you list anything you have taken, so I can check them for you.

I had a hair drug test done and it came back positive, then I had another one did 20 days later, which came back negative. What could have change the out come. and is it not true that you can not get drugs out of your hair unless you cut it bald.

I'm a veteran and take a variety of medication to help with pain, & PTSD. I recently had deviated sectum surgery by an ENT MD. I took a body hair test an it's showing cocaine of 81.2 pg. I never used cocaine. Also, took uranalysis - negative for cocaine.
Anyone know how this is possible. I requested the body hair test results & scheduled an appt with my Primary Care Physician to get to the bottom of this test result. As I stated earlier, I take a lot of difference medication (to many to list), and just wondering if it's possible that one of the medications could have caused this false positive?

I took hair test with DISA, came back positive for cocaine. As soon as I found out, I took other hair test with LabCorp (negative cocaine). I tried everything to have DISA re-run a test. They would not, I even took a 3rd hair test with a DISA certified lab (negative). I truely believe the 1st test was contamination.

Any advice?

My name is Felicia from Aurora IL. I had a problem with dcfs (catholic charities) And i was dropping for 1 year for them and everything was fine .then one day i got a call from the caseworker saying i had a dirty drop. I was so upset because i knew i was clean and they stopped all visits with my children. Well i paid out of my pocket at the same place to do a blood test and a hair test and they both came back negetive. The Lord knows i am innocent and i need someone to help me please.

Felicia, I am a retired social worker and understand just what you are going through and ask that you never stop praying and believing God knows you are clean and keep testing or do whatever they ask if possible. I know money may cause problems if you are asked to do the testing but I am sure your church family will be there for you. There are reasons for positive test results, medications, UTI, Kidney problems and in my case a friend came back from a mission trip with this really great tea! Helped my energy, weight and just a all around better me until I found out the hard way it was made with coco leaves. Just look at all you have intake in medication or any extra you may be surprised. Good Luck

I pee twice a week with a nurse in the bathroom standing right in front of me.I haven't used anything since early September and it's almost the end of February now.Anyway every time I pee it's negative for everything except methadone which I am prescribed. Occasionally the clinic send our urines out to a lab and my most recent one was positive for metabolites for cocaine...wtf...now I will be screwed on my next hair test involving family court...the only new products I have used are voltaren gel,a new secret deodorant and this face primer by hard candy....now I think my doctor thinks I am up to something.How can I be negative twice a week for coke but positive for metabolites....help!! Need advice on where to go from here..need a way to prove I am innocent

Megan..I totally get it.im in the same boat as u as far as children etc...I did a hair test in Han that showed positive for opiates..my last dirty pee was August so I guess it's possible but....then I paid again for another test which still showed opiates and cocaine as well.i am just a mess now! My nerves are so bad! I haven't used since my dirty pee in August which was opiates anyway and I cannot figure out for the life of me how cocaine has suddenly re-entered my life..without my knowledge! I used coke pretty heavily for about 5 years but none at all for ages..there's no reason for it to suddenly pop up! Damn.

Can cocaine show up in a hair follicle drug test from touching it? And how long will it take to go away?

I've recently come to find out that MY hair tests have most likely come back dirty for coke because of " passive exposure" ...I haven't used in over a year and couldn't figure it out,talked to a couple of doctors and they just said " well it's there so u did it"... I'm on methadone so thank God I've been going to my clinic and peeing clean for a year plus so I have that on my side....maybe that might give u somewhere to look....PS. I was dirty for coke but it didn't have any metabolites in it

Was it a pretty detailed test? I did a couple that just said either negative or positive and when it showed positive for coke after about a year of not using I nearly s*** myself. I ended up finding another lab that does segmented and quantitative testing...anyway this time it came back positive still for coke BUT it showed that I hadn't ingested it because it had no benzoglyconines or metabolites or whatever in it. Therefore it was determined that I somehow came into contact with it somehow.

It happened to me to I have been clean for 140 days from cocaine and it came back up positive for the three months I think wat u should do is pay for your own test or get it done in the programs and don't agree to it if u really didn't do it

The only substances I've taken within the last 5 months were norco 10 and percocet due to an auto accident. My last dose was 3 months ago. I've never taken cocaine.

I had a false positive for cocaine & suboxone. A true positive benzo & methadone. I'm on methadone split dose 80x80 morning/night. I've NEVER had coke (truthfully haven't & I don't see myself better for not). I took a xanax a couple days beforehand and paid to have a breakdown retest. I was NOT positive for suboxone or coke. With suboxone obviously I would have deathly ill withdrawal bcuz the false positives were from having sex with my husband that morning before I was dropped. This IS A TRUE FACT.

I have never done cocaine but it showed up in my hair follicle test. I am on clonidine, hydrochlorothiazide, metoprolol & hydralazine for blood pressure. Plus I have a prescription Flonase nasal spray to use as needed. I have a bad knee, for which I take otc Tylenol. At one point I was taking them like 6 a day for 15 days for pain because I fell down the stairs at home. Would that cause a positive hair follicle?

Can someone please help? I've been to the doctor twice and take an oral drug test where they put something in my mouth with cotton as well as a urine drug test, both supervised. My test results came back showing high levels of cocaine metabolite in my oral swab, but negative in my urine. I would never do cocaine. Can anyone tell me how this is possible? I've taken a blood test that came back negative also.

I'm on Lidocaine Hydrochloride, Baclofen, Meloxicam, Oxycodone and Oxycontin. My urine came back positive for Cocaine or Benzoylecgonine.

What I had read about is that some of the Medication {Lidocaine Hydrochloride, Baclofen, Meloxicam} that I'm on, could make my urine false positive for Cocaine. I'm no Doctor, that is just what I have read on-line. I don't know WHY I can not get an answer for this.
