The true pioneer in the field of psychedelic research, Bill Richards has been working with psychedelics since the 1960s. Trained as both a psychologist and a theologian, he played a key role in the revival of psilocybin research at Johns Hopkins. In this interview, filmed at the Psychedelic Science 2025 conference in Denver, we look back on the early days of psychedelic science, explore the healing power of mystical experience, and reflect on what it means to walk the paths of both science and spirit.
