A member asked:

Does a perscription of ibuprofen 600 or 800mg come up as a false positive for marijuana on a drug test?

See below: I have heard that Ibuprofen can test falsely positive on an initial tox but I have not seen it in thousands of tests that I have performed. It certainly will not be positive on gcms confirmation.
