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?
