I don't smoke but my wife does. She recently tried to quit and even resorted to trying Chantix but it didn't work for her. I even tempted her with the bribe of getting her cosmetic surgery if she quit (no plastic surgeon would do that kind of operation with someone who hasn't quit for at least a month and stayed smoke free for a month afterwards) but it didn't work.
She likes a smoke and that's all there is to it. I'm pretty sure if someone doesn't find her attractive because she smokes then so be it. We joined the lifestyle to have fun but mostly be ourselves and won't change because someone else has standards that are different than ours.
