You are 14, you still have time to grow. As Zach said, you won't grow amazingly tall, but chances are you will be average height. If not then a little bit shorter than average, but that doesn't really matter. Women are naturally shorter than men so not growing a few inches won't disadvantage you that majorly.
As far as I am aware of, smoking doesn't greatly stunt growth. I can't see it helping you grow either. Stopping smoking is a very good thing as it reduces other health risks, so congrats on cutting down. Let's just hope you can quit completely!
