Come November, at least nine states will vote on marijuana initiatives. Five of those states, including California, will decide whether to legalize the recreational use of pot.

Who might vote in favor of such laws? Perhaps you picture the typical stoner types like Cheech and Chong, Jeff Spicoli, or the Dude from The Big Lebowski. Pop culture has certainly fostered stereotypes about marijuana users. Now, a new study published this month in the Journal of Drug Issues gives us a more accurate picture of who really uses pot.

Steven Davenport co-authored the study. He's also a Ph.D. student at Pardee RAND Graduate School. Alex Cohen talked to him about what he learned from the working on the study.
