Yes you can test positive. The percent of folks won’t. With any NSAID and Prilosec things for GERD or acid reflux also can cause a false positive for THC
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 )
Yes
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 ;-)
Do not feel bad, I took a drug test today and came up positive foe THC. I am on prescription strength Ibuprofen and naproxen, and I do not take any illegal drugs period. Employers are really becoming cheap when it comes to urinary drug test. The specimen test they performed on me cost $4.75 cents. How accurate can being cheap actually be!!! If my test were sent to a lab, I would of passed it no problem because when you list the medications you are currently taking, it helps the lab tech compare the two meds to the actual cannabinoids found in using marijuana.
okay. so. I took neproxen Wednesday and the. again Monday. I got drug tested Tuesday and I passed
I took one and it was sent to a lab. THC in it and I don't use. I took naproxen, that's it.
It only happens 2.5% of the time, not always but it does happen. It happened to me
Me too, look at all the idiots that don't know what they are talking about.

Maso does know his stuff! He often offers great advice! Some of those things on the list are a little outdated though. Like poppy seeds causing false positives for opiates. They have actually changed lower limits on the tests so that poppy seeds wont fail you anymore unless you are eating them by the pound! They have changed quite a few of the tests and they are a lot better than even a few years ago but sometimes they do still see false positives. If one gets a false positive and the false positive will cause you to lose a job or go to jail then it should be confirmed by a GC-MS test. GC-MS (gas chromatography-mass spectrometry) tests are very accurate. They are VERY expensive though so they are not usually used as a first line test. Not meaning to dis you or anything Maso! I think you are great and you do know your stuff! :)
Dzoobaby, to be very frank I have read all your posts , and they are very good... you do know your stuff as well.
Thanks Maso!
You are very welcome DzooBaby.-
Naproxen (Aleve) - Can cause false positive for THC (marijuana).
Take care.
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.
ok thanks!!!
TY (((((((((((((((((((((((((((DzooBaby))))))))))))))))))))))))
u lightened things up
lol janymak ia m just feel so less alone u know what I mean?
Yes u can!! B4 u answer something, make sure u know what u are talking about!
This is incorrect. Read any medical journal and you will find that high concentrations of naproxen 1000mg+ chronic use daily, has the possibility of giving false positive results for THC.
For that matter, most common OTC NSAIDS can do this as well.
