Lester Grinspoon, born on 24 June 1928 in Newton, Massachusetts, USA, founded the Annual Review of Psychiatry and the Harvard Mental Health Letter, of which he was editor in chief for 15 years.
His interest in cannabis dates back to the 1960s, when recreational use of the plant was on the rise. Grinspoon's research began in 1967 under the assumption that cannabis was a very dangerous drug. He hoped to write a book in which the many dangers of cannabis were scientifically supported. As he learned more about the plant, its long history and unique properties, his plan changed.
Since the publication in 1971 of his by now classic book Marihuana reconsidered he has lobbied tirelessly for rehabilitation and against criminalization of the plant.
