In Oregon and Colorado, you can book an appointment for psilocybin therapy, where a licensed therapist takes you on a guided trip using the drug that makes “magic” mushrooms hallucinogenic.
Under federal law, psilocybin is illegal. But within the past few years, both states greenlit the drug for supervised medical use, and New Mexico may soon follow. It’s being used to treat certain conditions, including drug-resistant depression and PTSD. With a lot more people taking the drug under state supervision, what are we learning about its safety and efficacy? Who is taking it, and can clinics make money?
Host Flora Lichtman checks in on the state of these programs with Colorado Public Radio journalist Alejandro Galva. Then, she sits down with geriatric and palliative care specialist Stacy Fischer for a research update on the therapeutic use of the drug, and the nation’s largest clinical trial for psilocybin use for advanced cancer patients facing mental health challenges.
Guests:
Alejandro Galva is the afternoon editor at Colorado Public Radio. He’s also the editor of their series “The Trip,” which covers the psychedelic therapy landscape in the state.
Dr. Stacy Fischer is a geriatric and palliative care specialist at UCHealth University of Colorado Hospital.

With so many dating apps—and so many people using them—why are a record number of American adults single? Is marriage as important as it was a generation or two ago? Evolutionary biologist and sex researcher Justin Garcia joins Host Flora Lichtman to talk about dating and mating, and what evolutionary biology can tell us about our need to form a “pair bond” … or not.
Read an excerpt from Justin’s new book, The Intimate Animal: The Science of Sex, Fidelity, and Why We Live and Die for Love.
Guest: Dr. Justin Garcia is an evolutionary biologist and executive director of the Kinsey Institute. He is the author of The Intimate Animal.

Our ability to imagine is part of what makes us who we are—not just as individuals, but also as humans. It turns out, though, that we may not be the only species capable of playing pretend. In a string of experiments, scientists sat down, set the table, and hosted pretend tea parties with a bonobo named Kanzi to see if he’d play along—and he did.
Producer Kathleen Davis chats with study author Amalia Bastos about Kanzi, what it means to imagine, and how our definition of “humanness” keeps changing.
Guest: Dr. Amalia Bastos is a cognitive scientist at the University of St. Andrews in Scotland.

Screens are ubiquitous in today’s world, and concerns about how they affect kids are mounting. Last month, Australia banned social media use for kids under 16, with some European countries poised to follow. But what’s the science on how neverending YouTube videos or TikToks affect kids’ brains and bodies? 
Joining Host Flora Lichtman to discuss are neuroscientist John Foxe and behavioral developmental pediatrician Jenny Radesky.
Guests:
Dr. John Foxe is Director of The Del Monte Institute for Neuroscience at the University of Rochester in New York.
Dr. Jenny Radesky is a developmental behavioral pediatrician at the University of Michigan in Ann Arbor. She’s also co-Medical Director of the American Academy of Pediatrics Center of Excellence on Social Media and Youth Mental Health.
