  :You're right, the drugs you mentioned are opiates since they're synthesized from thebaine.  But, as it has been explained to me, the lab can legally report ONLY three opiates for a NIDA test.  That is morphine, codeine, and 6-acetylmorphine.  There are plenty of other opiates and metabolites, but legal guidelines for the NIDA panel are in the way, not the technology.  The federal government decides which drugs are *allowed* to be reported on this test.  So even though the lab may see a bunch more drugs on the confirmation result, federal guidlines require they only report those three.  So even if the person has a bunch of hydromorphone, hydrocodone, or oxycodone the lab can't legally report it.  It's silly I know, but hey, that's the government for you.   :So yeah, the lab has the ability to report all the drugs in the sample, but the federal government sets the rules for the NIDA panel, and the labs go by it.
