No, but if that was all there was to heroin I don't think we'd be seeing people destroying their families and literally throwing their lives away for it. Quitting smoking was a few weeks of feeling a bit shitty followed by a few months of constant cravings followed by almost forgetting you ever smoked.
Ah, I see. I was thinking more about the neurological side, which seems to suggest that similar mechanisms apply in addiction and withdrawal between nicotine, heroin and cocaine. (see for example [1])
As far as sociological consequences go, there's of course no comparison for various reasons. I don't know the role withdrawal plays, though, which is why it would interesting to get some first hand account.
