#260 Tommaso Barba — The Science of Psychedelics: 5-MeO-DMT, Brain Aging & Mental Health
What happens when the brain temporarily lets go of the identity, memories, and personal story that make you feel like “you”? In this episode of the Longevity & Lifestyle Podcast, Claudia speaks with Tommaso Barba, psychedelic researcher at Imperial College London, whose work explores consciousness, ego dissolution, 5-MeO-DMT, mental health, relationships, and the nature of the self. Tommaso explains why psychedelics are returning to mainstream science after decades of prohibition, how psilocybin, LSD, DMT, 5-MeO-DMT, MDMA, ketamine, and ibogaine differ, and why pharmaceutical companies are now investing heavily in psychedelic medicine. They examine the limitations of conventional psychiatric treatment, including the idea that depression is simply a chemical imbalance, and explore why psychedelic experiences may reach psychological, emotional, social, and spiritual dimensions that existing medications often do not address. Tommaso also shares his personal high-dose psilocybin experience, describing the dissolution of his identity, a sense of boundless awareness, and the challenge of returning to ordinary life after experiencing profound presence and connection. This conversation does not present psychedelics as casual shortcuts. It explores the importance of preparation, set and setting, skilled facilitation, integration, contraindications, and the cultural structures needed to support these powerful experiences safely.
