In this episode of Made for Health, Dr. Aaron Hartman sits down with Dr. James T. Leathem, DO, a board-certified anesthesiologist and psychedelic integration coach, to explore ketamine therapy, psychedelic medicine, and a different way of thinking about mental health. Dr. Leathem shares his unconventional path from business to medicine, how a near-death experience helped redirect his life, and how his background in anesthesia eventually led him into ketamine-assisted care. The conversation focuses on depression, PTSD, trauma, chronic pain, neuroplasticity, and the importance of pairing the medicine with meaningful integration work.
Dr. Leathem explains that ketamine is a dissociative anesthetic used at sub-anesthetic doses in this setting. He describes how ketamine interacts with the glutamate system through NMDA receptor blockade, which can influence AMPA signaling and brain-derived neurotrophic factor, or BDNF. He connects these mechanisms to synaptic plasticity, dendritic spine formation, and a period of increased neuroplasticity that may create an opportunity for new patterns and behaviors.
But for Dr. Leathem, the medicine itself is only part of the process. He emphasizes preparation, intention, integration coaching, mindfulness, journaling, sleep, and daily practices after treatment. His analogy is simple: ketamine may help put out the fire in your "mental health house," but it cannot rebuild the house for you. That rebuilding requires active participation after someone becomes unstuck.
The conversation also expands into the default mode network, spiritual experiences, stellate ganglion blocks, autonomic dysregulation, traumatic brain injury, and the wider landscape of psychedelic medicine. Throughout the episode, Dr. Leathem emphasizes individualized treatment rather than a cookie-cutter approach.
