Samhita of Feministing asks, "Is smoking weed a feminist act?" She cites an article from Seattle's The Stranger about male-dominated mainstream pot culture in which, "Men are allowed to be lazy" but women are held to a more ambitious standard.
I have to agree, I never thought of pot as a male activity, probably because many of the women I knew in college were just as likely -- if not more likely -- to toke up as our male classmates. On the other hand, when pot is depicted in popular culture (Road Trip, Half Baked) it's depicted as a male activity. You almost never see women toking up on screen unless it's some kind of cheesy after-school special.
I think this may be one of many instances where popular culture inaccurately reflects real life. Thoughts?
