Prohibition
Prohibition in the United States focused on the manufacture, transportation, and sale of alcoholic beverages; however, exceptions were made for medicinal and religious uses. Alcohol consumption was never illegal under federal law. Nationwide Prohibition did not begin in the United States until January 1920, when the Eighteenth Amendment to the U.S. Constitution went into effect. The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Prohibition in the United States
However, some scholars have attributed the crime during the Prohibition era to increased urbanization, rather than to the criminalization of alcohol use. In some cities, such as New York City, crime rates decreased during the Prohibition era. Crime rates overall declined from the period of 1849 to 1951, making crime during the Prohibition period less likely to be attributed to the criminalization of alcohol itself.
