In the United States, 33 states and the District of Columbia have passed medical marijuana laws (MMLs), while 10 states and the District of Columbia have legalized the recreational use of marijuana. Policy makers are particularly concerned that legalization for either medicinal or recreational purposes will encourage marijuana use among youth. Repeated marijuana use during adolescence may lead to long-lasting changes in brain function that adversely affect educational, professional, and social outcomes.1
