Who has legal authority to establish marijuana law and regulations — the federal, state or local government? How should the law treat motorists who drive while high? Should employers test workers for marijuana use in jurisdictions where the drug is legal?

Those are a few of the questions Vanderbilt University Law School students will tackle in professor Robert Mikos' marijuana law and policy seminar next semester — one of a growing number of law school classes focused on marijuana.

“For most students, this is an inherently interesting topic,” Mikos said. “They read about it in the media all the time, and so many are curious about it. As more states confront this issue, the interest will only grow.”
