What shows up as an opiate on a drug screen?

Answer 1

A false negative! Usually people claim the results are a false positive. I suppose the drug could have been metabolized enough not to show up on a screen.

It is possible the test was done incorrectly or the test kit itself was faulty (old or somehow damaged).

Answer 2

Usage of heroin does. So does vicodin, percocet, tylenol-3 with codeine, oxycontin, or other opiate type painkiller requiring a prescription.

Answer 3

pain meds:percocet,vicodin, lortab, dilauded

Answer 4

Nothing, if you get a positive show, you have opiates in you.
