during the psychedelic era. Research and publishing In the 1990s, Mason met and studied with the author and scholar, Terence McKenna. Mason intensively studied the work of Jonathan Ott, the ethnobotanist, whom he knew personally. Mason knew and frequently met with many experts and academics in the fields of ethnobotany, archaeology and psychopharmacology. In Oxford, Mason met the Professor of Archaeology Andrew Sherratt and the anthropologist, Marlene Dobkin de Rios. In the late 1990s, Mason worked with the author, Brian Barritt, a colleague of Timothy Leary. In 1998, Mason published Barritt's autobiographical psychedelic odyssey, The Road of Excess, to critical acclaim. Personal life Mason's first marriage to Virginia Lee was dissolved in the 1970s, and he remarried in 1980. Mason is survived by his wife, Ginny Mason, and his children, Paul, Carla and Nik. Cultural and political impact Mason's impact was to heighten the public's awareness to the injustice of the drug laws and to present alternatives for a better and more humane future. An inveterate campaigner for the human right to cognitive liberty, he will be remembered for the fight for civil rights denied to citizens in the 20th and 21st centuries. That Mason's impact came at a time when moderate drug policy reform was achieved was encouraging for him, but he continued to lobby and protest for full cognitive liberty as a basic human right in any civil society.
