Following nearly two decades of regulatory reform in the states, marijuana law and policy has
emerged as a robust and fascinating field of study. Abandoning the strict prohibitions that
dominated the previous seven decades, and that are still in effect at the federal level, more than
forty states have legalized marijuana in at least some circumstances. The reforms have sparked
lively debates about the content of marijuana regulations, the wisdom of competing regulatory
approaches, and the authority of different government actors to choose among them. Who may use
and supply marijuana under state law? Does legalization increase use of the drug? Could the
President legalize marijuana without the passage of new congressional legislation? May the states
legalize the drug while Congress forbids it? Even so, are state licensing requirements and similar
regulations preempted by federal law? May lawyers provide legal services to state-licensed
marijuana shops? These are a just a few of the intriguing questions that are now being confronted
in this field and that will be addressed in the course.
