while opiates may show up on drug screening test if you are prescribed them for a medical problem disclose this up front this should not be considered a "failed" test. if you taking these drugs recreationally without a valid medical prescription this would considered a failed test.
will i fail my hair drug test because of my perscription medication? . i took lortab for over a year. i do not abuse my perscriptions but a few months ago the dr put me on percocet. recently i went back to dr and got norco. sometimes i take more than my perscribed dosage will they detect that in my hair drug test and fail me?
