Dr Sam Gandy is involved with cutting-edge research into psychedelics and nature connectedness. He's worked with the Beckley Foundation, Onaya Science and the Centre for Psychedelic Research at Imperial College London. In this conversation, Sam explores the capacity of psychedelics to influence human relationships with nature. The research suggests that the psychedelic experience can enhance nature connectedness: We consider the evidence and the factors that might underpin this phenomenon. We explore connectedness, mysticism, ego dissolution and how we might use ecotherapy to enhance psychedelic-assisted therapy.
