Hallucinogenic Experiences Vary By Age: Dr. Thomas Roberts with Dave Asprey

In this brief exchange, Dr. Thomas Roberts and Dave Asprey explore why hallucinogenic substances produce different outcomes across individuals. They argue that a combination of personality, current emotional state, and biological health—particularly age-related liver and kidney function—affects how psychedelics are experienced. Roberts suggests that LSD (acid) may be easier on the liver than psilocybin mushrooms, making it a preferable choice for older adults. The conversation also touches on more speculative ideas, such as Stan Grof’s theory that planetary positions (e.g., Saturn) could influence psychedelic experiences, which Roberts acknowledges but remains uncertain about. Overall, the dialogue highlights both physiological and potentially metaphysical variables that modulate psychedelic effects.
