Hard to say. I used to be a cigarette smoker. Nowadays, I only smoke weed (but I roll my joints with tobacco). I actually quit smoking cigarettes, by and large, by replacing each cigarette I'd smoke with a joint or a bong hit. The tobacco in there, for me, is just a mixer and does not make me crave cigarettes at all.
You can minimize the effects of the nicotine by lightly "toasting" your tobacco beforehand.
But the tobacco in weed, for me, was always separate from, well, cigarette tobacco. However, I was never really addicted to nicotine, but smoking (and that's why replacing cigarettes with joints was so effective).
