oxycodone is like 3x more potent.... pretty sure. It's 2-3x morphine orally and I think that is roughly equal to hydrocodone's potency mg for mg.
hydrocodone most seem to agree is more sedating, however I think we all can agree that oxycodone is far more potent in regards to it's ability to induce a nod. It's stimulating at lower to moderately high doses but it's all based on many many many factors that we can't speculate on, but to be blunt, high dose oxycodone is way stronger, more dangerous, and tends to be the DOC of more long-term opioid abusers and is a decent breakthrough medication for chronic pain, can't say that for hydrocodone...
Anyways, we don't allow these types of comparison threads, check the OD guidelines and perform a search because we have covered this topic many many many times.
