Ask her out on a date, if you get on ask her if she could cut down on her smoking and give up one day soon as you want her to live for as long as possible and not deny the world her beauty and talents through slow suicide with a stupid toxic substance
OR
if she's hot and you really want her. Then well, there are mints and if she's sitting up on top you won't smell her too much/ from behind, face down.
Just don't kiss her too much
