#030 Roland Griffiths, Ph.D. on Psilocybin, Psychedelic Therapies & Mystical Experiences
Dr. Roland R. Griffiths, a Johns Hopkins clinical pharmacologist, discusses his research on psilocybin for treating depression and anxiety in cancer patients, its effects on the default mode network, and its potential for addiction treatment. He also highlights the importance of meditation for mental well-being.

5 Key Concepts
Classic Psychedelics
A category of serotonergically mediated hallucinogens like LSD, psilocybin, DMT, and mescaline, known for producing deeply personal and spiritually meaningful experiences that are valued long after the event.
Mystical-Type Experiences
Profound states of consciousness characterized by a sense of unity, interconnectedness of all things, sacredness, truth value, positive mood, and transcendence of time and space, often described as ineffable and leading to personal reorganization.
Default Mode Network (DMN)
A brain network associated with rumination and self-referential processing, which shows increased activity in depression. Psilocybin and long-term meditation appear to decrease activity and connectivity within this network.
Hard Problem of Consciousness
The fundamental question of why and how we are conscious, and whether consciousness can be fully explained or reduced to neurophysiological processes, highlighting the immense complexity of understanding subjective experience.
Neuroplasticity
The brain's capacity to change and reorganize its connections, which is believed to be affected by psilocybin, potentially underlying the 'reorganizational experiences' and long-term changes observed.
9 Questions Answered
Psilocybin experiences are deeply valued months or years later, with people reflecting on them daily and attributing long-term changes in attitudes, moods, and behavior.
Yes, studies show psilocybin can produce large and sustained decreases in anxiety and depression in patients with life-threatening cancer, with effects lasting up to six months after a single treatment.
Psilocybin primarily binds to serotonin 2A receptors, but its major effects are likely downstream and glutamate-mediated, potentially involving neurogenesis and changes in brain connectivity.
Acutely, psilocybin appears to decrease activity and connectivity within the default mode network, which is associated with rumination and self-referential processing, similar to the effects observed in long-term meditators.
A pilot study showed an 80% abstinence rate at six months for cigarette smokers treated with psilocybin embedded in cognitive behavioral therapy, suggesting its potential for radical reorganization.
Risks include immediate physical harm (e.g., putting oneself or others at risk) during 'bad trips,' and enduring psychological problems requiring professional help, especially if taken without support, in uncontrolled settings, or by vulnerable individuals with pre-existing psychiatric conditions.
Yes, the effects, including the probability of mystical-type experiences and challenging experiences, are dose-dependent, with higher doses increasing the likelihood of very difficult experiences.
No, while psilocybin can be a 'crash course' in exploring the nature of mind, it does not lead to the stability of awareness that meditation provides, which is considered the tried and true path for understanding mind.
Salvinorin A is a short-acting dissociative hallucinogen that produces a profound altered reality experience, sometimes with other entities, but generally does not lead to mystical experiences or the reorganizational meaning seen with classic hallucinogens.
11 Actionable Insights
1. Maintain Daily Meditation Practice
Engage in a daily meditation practice, as exemplified by Dr. Griffiths, to explore the nature of mind and foster mental well-being over the long term.
2. Explore Mind Through Meditation
Utilize meditation as a tried and true method to turn attention inward, observe mental processes, and become familiar with how your mind works.
3. Develop Thought Management with Meditation
Practice meditation to cultivate the ability to watch thoughts arise and then release them, a skill that helps untangle you from self-referential rumination.
4. Decrease Default Mode Network Activity
Engage in long-term meditation to decrease activity in the default mode network, which is associated with rumination and self-referential processing linked to depression.
5. Use Sauna for Stress Relief
Incorporate sauna sessions into your routine to potentially improve stress handling, lower anxiety, and experience lasting positive effects on your mood and well-being.
6. Don’t Substitute Psilocybin for Meditation
Understand that psilocybin is not a substitute for meditation, as it does not provide the stability of awareness states necessary for a deep, sustained understanding of the mind.
7. Avoid Casual Psilocybin Use
Refrain from casual or unsupported use of psilocybin, as it carries risks including physical harm, enduring psychological problems, and potential danger for vulnerable individuals.
8. Recognize Psilocybin’s Context Dependence
Be aware that psilocybin’s effects are profoundly influenced by the context (set and setting) and pharmacology, making casual use without proper support and preparation risky.
9. Screen for Psychotic/Bipolar History
Note that individuals with any even second-degree relative having a history of psychotic or bipolar disorder are screened out of psilocybin trials due to potential vulnerabilities to negative effects.
10. Consider Psilocybin Dose Effects
Understand that the probability of both mystical and challenging experiences with psilocybin increases with dose, with very difficult experiences significantly increasing at higher doses (e.g., between 20 and 30 milligrams per 70 kilograms).
11. Respect Traditional Hallucinogen Use
Acknowledge that indigenous cultures historically use hallucinogens in highly controlled cultural contexts for religious, healing, or divination purposes, not casually, underscoring the importance of structured use.
8 Key Quotes
psilocybin, under conditions in which people are very carefully selected, they're supported, they're prepared, has effects that are deeply and profoundly personally and spiritually meaningful to people.
Dr. Roland Griffiths
these experiences are deeply valued well after the experience has finished. So months later, people continue to reflect back on that experience and opine that it's among the most personally meaningful and spiritually significant of their lives.
Dr. Roland Griffiths
The central feature is this sense of the interconnectedness of all people and things. It's a sense of unity.
Dr. Roland Griffiths
it's more real and more true than everyday waking consciousness.
Dr. Roland Griffiths
it's reorganizational to how they hold themselves and other people in the world.
Dr. Roland Griffiths
psilocybin looks very much like meditation in that regard. So there's decreases in the default mode network.
Dr. Roland Griffiths
personality theorists would tell you that doesn't happen. You know, those personality characteristics are, are locked in kind of from mid twenties. And if anything, openness decreases then across the lifetime. And here you see an increase in openness.
Dr. Roland Griffiths
psilocybin might be the crash course in that.

1 Protocols
Psilocybin Session Protocol (Johns Hopkins)
Dr. Roland Griffiths- Spend at least eight hours of preparation with volunteers to develop rapport and trust, ensuring they feel safe during a high-dose experience.
- On the session day, volunteers take a capsule of synthesized psilocybin.
- Volunteers lay down on a couch with eye shades and headphones, listening to a program of music.
- Volunteers are invited to direct their attention inward on their inner experience.
- Two facilitators are present to provide reassurance if needed and ensure safety, making people feel secure despite potential anxiety or fear.
