How well do you know her? Thats a big factor in this problem, if its just some girl you've observed in classes, and haven't really talked to, you can probably become friends w/ her but nvr mention anything about toking.. It can really mess up relationships (my last one was cut off partly because she wasn't ok with mj).. Or if your already good friends with her, you can warm up to her, talk to her and maybe ask her some personal-ish questions about what she likes in guys etc, to show her that you want to get to know her (date).

But if your sure shes pretty anti-mj, just take it slow and leave her in the dark, at least for the initial stages of dating, it could hurt worse if you don't ever tell her, and then a year later she finds out you smoke...

Blah blah rambling. :thumbsup:
