I've had a similar experience; a mild dose of oxycodone had no high, no withdrawal, and unremarkable pain relief. Individual variability is pretty high with opioids, both in efficacy and in metabolism speed. It's more pronounced with things like tramadol, but also true of oxycodone. At a guess, you might just be seeing much less impact from a given dose than other patients (and likely addicts might well be seeing more).
