hmm. the guys i know who smoke pot outnumber the girls, as is usually the case, but i'm female and smoke several times a week. about half my female friends smoke, and 3/4 of the guys.
being a girl is a beautiful thing. i get smoked up for free all the time; the only time i've ever paid for weed was when i bought 1/4th to bring on a two-week vacation. i suppose guys are just hoping we'll eventually fuck them, though i've never given a sexual favor to someone who's smoked me up. ;b
also, it's funny that guys think girls are somehow less apt at smoking pot. i don't know how many times i've had someone who doesn't normally smoke with me say, 'whoa, she takes mad bong hits for a girl.' psh.
