Sacred Weeds was a four-part television series of 50 minute documentaries investigating the cultural impact of psychoactive plants on a broad array of early civilisations. The series was filmed at Hammerwood Park by the producer, Sarah Marris, and her production company TVF. It was broadcast in the summer of 1998 on Channel 4, a British television network. The Reader in European Pre-History at the University of Oxford, Dr Andrew Sherratt, was the series host. Prior to his resignation from the University of Oxford, Sherratt was appointed Professor of Archaeology. Each episode began and ended with Sherratt inscribing his diary with his reflections on the series' scientific and cultural investigations. In each episode the series investigated one psychoactive plant and its cultural significance. Three specialists of various scientific disciplines were invited to monitor two volunteers who had taken each plant. After the four episodes, Sherratt assigned considerably more significance to the psychoactive properties of plants in ancient civilization and the prehistoric period than expert knowledge hitherto.

scientists:
Michael Carmichael, Ethnobotanist/Anthropologist
Dr Cosmo Hollstrom, psychiatrist and lecturer at Imperial College
Dr Joanna Iddon, from CeNeS Cognition
volunteers: Ed Turpin, Johnny Green Memorable moments include a long haired participant in baggy clothes, athletically climbing a large tree and yelping with excitement. The clinical and skeptical approach of Dr. Cosmo contrasted with the psychological and forensic approach of Michael Carmichael. The two scholars debated the significance of research into altered states of consciousness.
Dr Susan Duty, pharmacologist at King's College London
volunteers: Robert Barnes, Marie McCartney The series ended with the investigation of the psychoactive effects of the Blue Lily, a sacred plant in ancient Egypt. Michael Carmichael suggested that the psychoactive effects of the blue lily and other psychoactive plants established a new foundation for understanding the origins of philosophy and religion in ancient Egypt. Alan Lloyd, the Egyptologist took a more cautious approach. After witnessing the effects of the plant in two volunteers, all parties agreed that it was a psychoactive plant. Sherratt accepted the new paradigm for the origins of ancient philosophy and religion in his summation of the series.
