Dr. Kevin Sabet explains the impact of marijuana legalization in states that approved it. Legalization has led to a steep rise in marijuana potency and increases in marijuana-related car crashes and poisonings, especially among very young children who eat marijuana-infused candies accidentally, he says. He spoke at Let’s Be Clear Georgia: A Collaborative to Prevent Marijuana Use, sponsored by the Council on Alcohol and Drugs on November 19, 2014.
