“Psychedelics and Civilisation, Light and Darkness”

Graham Hancock investigates the possibility that by demonising and criminalising the use of psychedelics, rather than seeking out ways to harness their power for altering consciousness in safe and nurturing spaces, our society may have set itself on a profoundly negative path — a path that might even deny us the next step in our own evolution as a species.

Horizons: Perspectives on Psychedelics is an annual forum that examines the role of psychedelics in science, healing, culture and spirituality. Website:
