Episode Details

In this episode of the Psychedelic Medicine Podcast, Dr. Joel Castellanos and Jim Harris join to discuss the possibilities of addressing spinal cord injuries using psychedelic medicine. Dr. Castellanos is a board certified physical medicine and rehabilitation and pain management physician and an associate professor in the department of anesthesiology at University of California, San Diego School of Medicine. Jim Harris is a National Geographic photographer who suffered a spinal cord injury during one of his adventures who became notable in the psychedelic space with the article in Outside "Jim Harris Was Paralyzed. Then He Ate Magic Mushrooms."

Jim starts off by sharing his own backstory of how he broke nine vertebrae in his spine during a 2014 ski expedition in Patagonia, Chile, leading to significant loss of motion and sensation. After some promising success in traditional rehabilitation and physical therapy settings, Jim details his surprising experience of healing with psilocybin.

In this vein, Dr. Castellanos discusses the importance of neuroplasticity in healing for spinal cord injury patients. He talks about how forming new neural pathways can help a patient regain function and sensation in a part of the body that had previously been paralyzed, and leveraging this neuroplasticity using psychedelics and other tools may be a promising way to improve outcomes among these traditionally underserved patients.

Considering the unique needs of spinal cord injury patients, Jim wonders whether lower doses of psychedelics may be more beneficial for this population, as it would allow them to maintain a greater degree of sobriety and groundedness to pursue physical therapy and rehabilitation activities while under the influence of the substance.

Dr. Castellanos expresses excitement about the possibilities of psychedelic therapies for these patients, as not only does early anecdotal evidence such as Jim's story suggest that these substances may be effective in helping to facilitate regain of function and sensation, but also because of the mental changes brought on by a psychedelic experience. Patients may feel more optimistic and eager to apply themselves following a psychedelic experience, which will facilitate healing beyond just what occurs as a result of the effects of the substance itself. He is also encouraged by current research into different forms of neuroplasticity which have different mechanisms. Dr. Castellanos suggests employing these in combination, such as using psychedelic therapy alongside vagus nerve stimulation, may offer more effective treatment options for spinal cord injury patients.

At the end of this conversation, Jim poses Dr. Castellanos a fascinating question: whether there may be any downsides to over-encouraging neuroplasticity. Dr. Castellanos responds that there could be certain risks of increasing pain in patients, as neuroplasticity encourages new connections to be formed in the brain, but it matters what specifically becomes more interconnected. As such, there is reason to proceed with caution even as neuroplasticity offers significant benefits.

In closing, Jim shares some hard reduction tips for other spinal cord injury patients interested in exploring psychedelic healing. Both he and Dr. Castellanos are optimistic at the possibilities of psychedelic therapies used in conjunction with other treatments for patients like Jim.
