River to River, hosted by Ben Kieffer

Psychedelic drugs like psilocybin and MDMA have become a very active area of medical research.

Psychedelic-based therapy shows great promise in treating disorders ranging from depression and anxiety, to chronic pain and PTSD. One of the populations that could benefit greatly from these treatments is U.S. veterans.

On this episode of River to River, host Ben Kieffer speaks with a Marine Corps veteran who now advocates for psychedelic-based therapy. Also, University of Iowa professor emeritus of psychiatry Dr. Michael Flaum and research scientist Candida Maurer discuss their research and an upcoming clinical trial. And an Iowa lawmaker discusses legislation related to the use of psychedelics.

This episode was originally produced March 16, 2023.
