Opiates make me itchy

And it's fun to scratch. But generally speaking. Why do they make me itch? I've snorted about 40mg oxycontin, and I'm starting to get the comedown...i hate comedowns.

i have only been on an opioid once (morphine, and it was being administered to me in a hospital for actual pain) and i was itchy too. as far as i know, opioids simply release a chemical that activates the itch response. exciting, huh? :)

Histamine, probably. Yeah, opiates make you itch, but not in a bad way.
