It doesnt matter to me wether they smoke tobacco or not, although some men look super hot smoking a cigarette, but I'd rather they smoke weed than tobacco.
Except for ocassional bud, I hate the smell of any smoke on my man, whether it's his breath or clothes. He showers as soon as he gets home from work, for that reason.
I smoke, so it would be hypocritical of me to judge a man for doing it. I'd be turned off by a man that dips (chewing tobacco) though....spit cups ain't sexy!
