What will cause a false positive cocaine result on a urine test?

Poppy Seed bagels can cause a false positive (Mythbusters proved it)...if you've eaten these it's probably why, but good luck trying to convince someone of that. When you take a drug test you are supposed to list all current medications you are taking. This should eliminate the possibility of false positive from them. Slight chance your sample was mixed/switched with someone else...but I doubt it.What will cause a false positive cocaine result on a urine test?
There are vitamins and pills out there that maybe the culprit. I know if you take sudifed it gives the result of marijuana, tg2000 (a vitamin in the early 90's) that I use to take had the same effect and I almost didn't pass a life insurance test. Figure out what's in the prescriptions you are taking, call the companies to find out what could be causing this effect, let your life insurance company know what prescriptions you are taking if you haven't done so already, they should have a break down of chemicals in the drugs that maybe causing this reaction. Best wishes to you.
There are a number of drugs that can setoff a false positive.





When you applied for coverage, the examiner would have asked for a list of the medications you take. Take a look at each medication to see if it could cause a false positive.





You then need to alert the insurance company if there was a drug that may have caused result and ask what steps they require to prove false positive.





Hurry up though as your MIB record will probably cause problems for you until this is resolved. If not taken care of, you will get declined every time you apply.
I am not sure about the medications, but it is pretty hard to get a false positive on Coke. Maybe someone you are intimate with used and while love making it got into your system. But honestly I am not sure?
