Now that Californians have legalized recreational marijuana, Davis is deciding how that change will play out here. Are retail dispensaries OK? How about outdoor growing? Cities and counties across the state face similar decisions. Two weeks ago we talked about Davis’ efforts to collect ideas and comments as City Hall begins to write the city ordinance. Two weeks from now, we'll present an interview with a marijuana advocate. For today's program we talk with Dr. Ron Chapman, Yolo County public health officer, to get his take on legal pot—what research says, lessons from Colorado (which legalized marijuana before California did), the importance of education in keeping marijuana away from kids and youths, ideas for local ordinances, and more.
