I don't think so.
No I had to stop smoking for my boyfriend because he said he could never date a smoker. If she likes you then you will win over her smokes
Not if the smoke is coming out of her ears and she is growling at you.
Umm... I don't think so. Think of it this way: Is it wrong to ditch a girl because she damages your health?
If she does it because she thinks it's cool then na it ain't but I've smoked a few times but not because I thought it looked cool, there were other reasons! x
That could be a reason if you feel strongly enough about it.
