First of all, I didn't compare Heroin IV with Codeine, I simply said that all opiates have the same effect spectrum and thus all of them get you hooked sooner or later you illiterate dimwit. Secondly, there is no fentanyl in our Heroin 910o. here in Germany my dear little dummy. There have been cases of fent ODs, but they are extremely rare and not the norm, so before you try to educate me about Heroin and fent, do some homework. I am aware that IV Heroin is quite a different animal but I haven't talked about that aspect in my post.
