A major psychedelics conference wraps up in Denver today. Its mission is to get more people, especially policy makers, comfortable with what has previously been underground. We speak with the founder of MAPS, the Multidisciplinary Association of Psychedelic Science, about the science and what's left to learn as Colorado licenses psilocybin healing centers. Plus a company in clinical trials, and an awareness campaign about the potential risks. Then, nurse Tara Rynders used to hold in all the trauma of the job. But through music and movement, she's managed to change that for herself and for other practitioners. Now she has a one-woman show, "A Nurse is Calling."
