In this episode, Martin talks to author Murray Carpenter about his new book Caffeinated: How Our daily Habit Helps, Hurts, and Hooks Us. Caffeinated leads us on a fascinating, sometimes disturbing tour of America's favorite drug, with stops at the coffee farms of central Guatemala, a synthetic caffeine factory in China, an energy shot bottler in New Jersey, and beyond. A well-researched look at the additivie that flows under the radar, Carpenter delivers a compelling compendium of facts and figures on this largely unregulated drug.
