That shouldn't be a problem to any rescuer who is prejudiced against smokers as the majority swear that smokers stink so bad they can tell they're a smoker from 20 feet away!
I'm anti smoking but there are a lot of people I know who smoke but you can't smell it on them...unless they just had one.
One colleague who used to work at our place and smoked quite a lot informed me one day that her husband didn't know she was a smoker. I was quite surprised that he didn't know and that it was secret although I must admit she didn't smell of smoke. She knew he'd go mad if he found out. She chewed sugar free gum all the time to prevent the smokey breath and he obviously never smelt it on her clothes.
I read up not long back too some article where loads of people smoke and hide it successfully from their partners....!!!
