I know
I understand that heroin is a prodrug, my point still stands. 
Codeine was for me......havent done Morphine yet & I heard you can get it pretty bad. I never get the itches with Oxy or Hydro.
Have you done heroin? If yes, then that's how the morphine itches are.
Because when you take heroin, morphine is what binds to the receptors and gets high. Heroin is just a prodrug for morphine.
6-MAM has activity of it's own
Very, very minor activity and 6MAM itself is quickly converted to morphine aswell. There's no way of getting around it, heroin is a morphine prodrug (it says it in all pharmacopoeia's). You think a pharmaceutical company wouldn't be badgering the DEA to place heroin on the market in the US (bring it to CII - why not? they got way more potent opioids on CII like fentanyl, hydromorphone, oxymorphone, levorphanol, etc). They can't because it's the exact same thing as morphine. It would make no sense. No pharmaceutical company would have a case. Morphine is the most active metabolite and the one that fills the opioid receptors when you do heroin.
oh im not disagreeing with you.. and trust me, I know all how heroin works... lol
i was just saying, it's funny how the "itchiness" factor defers between morph and dope with me
