Naproxen is an nonsteroidal anti-inflammatory (NSAID) drug and is not a controlled substance so therefore should not cause you to fail a drug screen.
Naproxen (Aleve) - Can cause false positive for THC (marijuana).

I took a drug test yesterday and it tested for THC. I DO NOT SMOKE AND THE ONLY THING I TOOK WAS NAPROXEN. I DO NOT UNDERSTAND HOW HEAD ACHE MEDS CAN DO THAT. GOOD LUCK TO EVERYONE ;-)
I'm prescribed 800 milligrams of naproxen twice a day or 1600 milligrams a day I just failed my work UA for thc so I asked if naproxen can cause a false positive and was told yes it can if taken chronically (over 1000 milligrams a day )
