If your problem is the smell, try to convince her to start smoking handmade cigarettes.
There are good brands of tobacco that dont include ammonia or coccoa in the mixture (do some research to why those substance are added), and generally the hand made cigarette tobacco is a lot less smelly of the factorymade cigarettes, for many reasons.
I use mainly the "Drum" brand. a lot of non smokers tell me that it almost dont smell or has a good smell.
And use Rizla papers, thin type.
Quit smoking, is a whole different beast (dont tell her this: ).
It's one of the stronger and harder phisical and mental adductions existing.
It can be said that after quitted, nobody is completely safe.
The worst periods are during the first 2-3 years, when the phisical reactions are still strong, and one may wrongly guess to be out and safe.
Oh, judging to the people that I know that have quitted smoking, the only real way to do it, is to.... well..... DO IT.
Just that.
And stick with the decision made.
(And you can tell her the above part).
