I like a girl that experiments with pot some times...i agree it shows they are outgoing and whatnot.
But if a girl smokes cigs to look cool, and she does it around me, I tell her to her face right before she lights up:
"Before you light that up, realize that if you do I will not kiss or touch you in any way tonight. Girls like you do not need to smoke to look attractive or cool."
I never like telling a girl that she is attractive or hot all AFC like, but in this situation that's what I prefer to say. Makes me sound more wise and mature, most girls, especially younger ones, get turned on by that stuff.
By getting with a girl that smokes, or even worse dating a girl that smokes, I feel I am lowering my requirements. I tell the girl if she wants to be around me, she's not going to smoke cigs.
And yes, if they smoke they are usually more open to physical stuff, although I don't like a mouth full of tar and cig chemicals sloshin around on my ****.
My 8 cents...
