If the smoking habit interfere or not in the relationship in the future, is a different thing.
I smoke rarely, but when I do, I try to not do in front of people who don't like smoking, so I do not smoke in closed areas with them, or I don't know. Is just a respect thing.
sometimes i like woman that smoke, but i don't want her to be my GF or wife. At least i tolerate if she is just a social smoker and she should be smoke it right (not like that b**tches that just smoke to look cool so she just faking smoke)
