As you may know, all ciggies are either mentol or regular - she should try one of each to get to know what she likes. They're both very different...ignore other things on the packs like lights, wides, special blend etc...all you need to know is regular and menthol.

If I were you, when I talk her I'd emphasize that this is just for a few years - so that you can at least know what it's like.

Tell her that some guys have a 7 year itch and want to sleep with other woman....but it's no so with you. SHE is the focus of your desire and all you want is to see her smoke for a few years.

Make sure she understands how important it is to you - i might even hint at leaving at her if she says no...but thats up to you. Laying out a hint like that requires great subtelty and alot depends on how the talk is going...don't say it if you're not prepared for the consequences.

Above all, if she agrees make her feel comfortable when she tries smoking. Make her feel good about it - not annoyed or disturbed or anything like that.
