"…Nearly every delinquent is a cigarette smoker."
Letter from Alva P. Jones, Superintendent, National Cigarette Law Enforcement League to President Herbert Hoover Stating that Crime is Due the Use of Cigarettes, 05/25/1929
President Hoover established the National Commission on Law Observance and Enforcement in May 1929 in an effort to identify causes of criminal activity. Thousands of citizens wrote to offer information and to express opinions about the causes of crime in the United States.
Alva P. Jones, Superintendent of the National Cigarette Law Enforcement Leagues wrote to President Herbert Hoover on May 25, 1929 suggesting that he stop the manufacture and sale of cigarettes. Jones argues that cigarette smoking is the cause of a great crime wave and a prohibition of cigarettes will solve it.
