Is it possible to fail a UA from a false positive and have 105ng of thc in your system?

Question

I heard it's possible to fail a UA because of a false positive but can that make 105ng of thc in my system? I failed a UA for probation and was wondering what the cut off limit is for saying it was a false positive! Is it fair to say I had too much naproxen?

Answer 1

naproxyn doesn't cause false positive marijuana tests. It's an anti-inflammatory drug.

The cutoff limit is whatever the probation department says it is ... and depends on exaclty which test they use.
