Is it possible to test positive for cocaine in a hair sample drug test without using cocaine?

I tested positive for cocaine even though I do not use any illegal drugs. This test was taken for employment. I've had my urine checked and no cocaine was found. Should I get a blood test or take another hair sample test and challenge the first results?

yes, it is possible. You can get things in your hair just by being in the are or around someone who had it. Thats why in most places a hair test is not considered reliable, because you can get false positive results. The blood and urine tests are the only two reli9able ones.

Yes it is. You need to get your prescription history from your pharmacist or physician and present this to the utility who did the test. Many prescriptions will make you test positive for opiates, especially pain relievers.

I would challenge the results it sounds like they screwed up on your first test.

Is it possible to test positive for cocaine in a hair sample drug test without using cocaine?

yes, certain foods will cause a drug test to come back positive. Also, certain medicines (I'm on a heartburn medicine that comes back as pot). Don't eat alot of poppy seeds (bagels, muffins, etc...) as that comes back as opium. I would challenge the results as the urine test came back fine, maybe a blood test would also validate that. Ask a clinic or a doctor.
