Actually, to be technical, yes and no. It will show up on a standard opiate test, but if it is a GC/MS test (the most advanced/prescise drug test to date) then it wont show up. The GC/MS test for opiates only picks up your natural opiates and their metabolites, and Oxycodone is a semi-synthetic opiate, so it would not show up on the GC/MS test.
But thats besides the point. Im sure it will show up on any standard opiate drug test you can buy from Walgreens/CVS.
