Hello. I am in a heated custody battle for my son in which I am winning. Then after months of hearings my exwife decided to allege that I was a cocaine addict. I admittedly (as did she) experiment with the drug many years ago. To put her mind at ease, I voluntarily said I would undergo urine testing as every 48 hours (within reason) for 30 days. Going into the second week, every test was negative. On the third week I took a test on Tuesday, Wednesday and Friday. Based on the sample times, the 3 samples were submitted in less than 72 hours. For reasons I cannot xplain, the Wednesday test came back with low level traces of cocaine (450). So 15 of 16 tests within 30 days were negative. I haven't done any recreational drugs in a long time. I'm currently taking Klonopin for stress, Aderall for ADHD, and Lexipro for depression. I'm not looking to attack the testing standards or the lab, I'm just looking for any and all reasons that might have casused that one test to show positive.
What are all the possible causes of a positive cocaine result in a urine test?

Antioxidants (amoxicillin) also the prescription drug Nuvigil
Hey JedKampe,
There are numerous drugs and conditions that can cause a false positive for cocaine not to mention human error.
"Substances that can cause a false positive drug test result:
Amoxicillin is an antibiotic in the penicillin group of drugs. It fights bacteria in your body. Ampicillin is another antibiotic similar to amoxicillin. Local anesthetics obtained from cocaine, excluding lidocaine and Novocain
Tonic water
Conditions that can cause a drug test to be a false positive
Liver infection or disease
kidney infection or disease
diabetes"
Do you drink tonic water by chance? Taken a penicillin type antibiotic or have diabetes?
Hope you find your answer,
Laurie
I know for a fact amoxicillin tests you positive for cocaine , I had a positive test and the only thing I took was amoxicillin I was prescribed by the doctors , its on my records , and the only bit of the test that showed up positive was when I took the amoxicillin , the other bit is clear , I think people going in for hair and urine tests , need to get a full list off their doctor of what they have been prescribed in the past 6 months , it should be company policy with drug testing companies , people need to be made aware that by taking a simple thing as a antibiotic will show u up as a drug taker when ur not , these tests need to be revised , because innocence people are having their lives ruined for as a simple thing as a antibiotic , and there quite a difference between taking cocaine and taking a antibiotic , if a test can not distinguish between a antibiotic and a street drugs then the test is not valid and should not be used
There should be something that can be done about this same thing just happen to me I'm going to go and see a lawyer next week to see what can be done about this
