The “noble experiment” of Prohibition was instituted by this amendment, only to be repealed 14 years later by the 21st amendment. Source: U.S. Senate
Ratified on January 16, 1919, the Eighteenth Amendment prohibited the making, transporting, and selling of alcoholic beverages. Adopted at the urging of a national temperance movement, proponents believed that the use of alcohol was reckless and destructive and that prohibition would reduce crime and corruption, solve social problems, decrease the need for welfare and prisons, and improve the health of all Americans. During prohibition, it is estimated that alcohol consumption and alcohol related deaths declined dramatically.
But prohibition had other, more negative consequences. The amendment drove the lucrative alcohol business underground, giving rise to a large and pervasive black market. In addition, prohibition encouraged disrespect for the law and strengthened organized crime. Prohibition came to an end with the ratification of Amendment XXI on December 5, 1933.
