On this week's episode of Issues and Ideas , we talk with author and journalist Michael Pollan about his latest book on psychedelic drugs, and the resurgence of research into how these substances can be used to treat addiction, depression and help us understand consciousness. We'll also hear part two of a recent documentary exploring the proposed Chumash Heritage National Marine Sanctuary , with interviews of various stakeholders in the waters off the Central Coast. We'll have more on a California State Parks plan to make significant changes to the Oso Flaco Natural Area and Oceano Dunes SVRA in San Luis Obispo County. And we get a history lesson on San Luis Obispo County's missions and libraries.
