Hi there, welcome to BDD. Please read the guidelines at the top of the forum. We don't do comparison threads as they tend to go nowhere and are a matter of opinion - consult Erowid or read Trip Reports here if you're after that information. If you have a HR-related question about either oxycodone or opium then feel free to make a new thread. If your initial post just says "..." then it's going to get closed though, you need to give us a bit more than that!
Closed - PM me with any queries.
