Kratom is often found at gas stations and convenience stores and is marketed as a natural supplement for pain and anxiety. Gov. Kim Reynolds is calling for a total ban of the product and other synthetic varieties, alleging dozens of kratom-related deaths in Iowa since 2024.

On this episode, highlights from a wide-ranging conversation with David Axelrod at Hancher Auditorium in Iowa City earlier this year.

This event, recorded live on April 28, 2026, was part of the Levitt Lecture series presented by Hancher Auditorium and the University of Iowa College of Law.
