Depends on test type: Confirmatory test with gas or liquid chromatography will give a definitive result. Heroin is metabolized to 6-AM and eventually to morphine. Codeine is metabolized directly to morphine. If your test was done with a test strip, I would challenge it's results. If it was GC or HPLC then you're guilty.
