Not under any circumstances.
No. Hydrocodone will only test positive for opiates. Hydrocodone will not test positive for cocaine metabolites.
Yes, Hydrocodone will test positive on a drug test for opiates and opiates are narcotics. If you have a drug test and you are being prescribed hydrocodone just take your bottle with you to the drug test and let the examiner see it . If you are not prescribed hydrocodone then you will fail the test.
Hydrocodone is an Opiate based painkiller, so no, It cannot test positive for Amphetamines - but it will on the other hand, Test positive for Opiates (Heroin, Morphine, Oxycodone ect.)
Yes. Hydrocodone is an opiate class drug and will test positive for opiates.
I'm not sure if the test would specifically test for Hydrocodone, it would most likely test for opiates, which are in both Hydrocodone and Morphine. So in short, yes, if the drug test is testing for opiates in your system, both Hydrocodone and Morphine will cause a positive for opiates.
Yes. Now I gotta know: why do this?
No. They are not even in the same category of drug. Hydrocodone is an opioid, Pristiq is an antidepressant.
No, hydrocodone is an opiod(which it will show up as on most test) and unrelated to amphetamine.
No, Vicodin will not test positive for cocaine. Vicoden (containing hydrocodone) will test positive for a narcotic. Hydrocodone and cocaine produce different metabolytes, which is what the drug test actually reacts to. A metabolyte is what the drug turns into after your body uses it. Each drug produces different metabolytes.
Nothing will.
In short, Yes. You will test positive for opioids.
hydrocodone can show up but diphenhydramine can't. they don't interact with each other to show a false positive for anything.
