Smoking?

Was in the middle up typing up the app for my new character on Bad Romance when I realized something.

Nicotine from cigarettes passes into the bloodstream from the capillaries in the lungs, and from there heads into the brain and localizes in various nerve clusters. Now, since vampire hearts don't beat and cause blood to flow, nicotine technically won't really affect them. Which means the benefits of smoking are negligible as the smoke will not reach the brain.
Of course, the detriments of smoking don't really hurt them either. I mean, what kind of vampire would die from lung cancer?

So, my question is this, besides looking sexy as hell, why would a vampire take up smoking after his turning? o.O
