When liquor was banned in 1920, hospitalizations for alcoholism and related diseases plummeted; in 1933, when Prohibition was repealed, alcohol-related illnesses rose sharply again. Legalization of cocaine, heroin, and marijuana would not curb abuse of those substances.

a) true beyond a reasonable doubt
b) probably true
c) possibly true or possibly false
