Due to Timothy Leary's highly publicized advocacy of the beneficial properties of LSD, the authorities were hoping to find legal means to incarcerate him. Richard Nixon called Leary "the most dangerous man in America," and when in 1966 his car was stopped crossing the Mexican border, Leary's daughter was arrested for the possession of marijuana. Leary took the rap and was sentenced to ten years in prison. He escaped in 1970, sought asylum in Switzerland, but was recaptured by DEA agents in 1973. His conviction was overturned in 1976. Jail Notes was written during the first seven months of incarceration, before Leary escaped and fled to Switzerland.
