Drawing on stress and life-course perspectives and using panel data from 1,286 south Florida young adults, we assess three critical questions regarding the role of marijuana in the "gateway hypothesis."

We hypothesized that VB teens would manifest a higher crash rate than Chesapeake teens. METHODS The Virginia Department of Motor ...
