This is Dr. David
ibuprofen and naproxen medications have been known to cause false positives for marijuana or cannabis in your urine.
I included a medical article about this.
Vimovo contains Naproxen in it
show your doctors this article
any urine screening positive results have to be confirmed with MS/GC Mass Spectroscopy/Gas Chromatography confirmatory tests which will test negative if you haven't used marijuana.
let me know if you have other questions.
