Hello from JustAnswer. This is Dr. Love.

It depends upon what type of urine test was done. There are various medicines that can cause a false positive urine screening test for THC, but they would not cause a false positive confirmatory test. None of the medicines that you list are reported to cause a false positive screening test for THC, but there are several medicines that have been shown to cause a false positive screening test. The most common are various anti-inflammatory medicines, including the over the counter anti-inflammatory medicines, ibuprofen and naproxen.

It is also possible that there could be a false positive urine screening test in someone that is not taking any medicines, because the technology will have a false positives in a fair percentage of cases. This is why it is recommended that any positive screening test should then be confirmed by a more accurate test, such as GC/MS.

If I can provide any additional information, please let me know.
