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 The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.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
In 1930 the Prohibition Commissioner estimated that in 1919, the year before the Volstead Act became law, the average drinking American spent $17 per year on alcoholic beverages. By 1930, because enforcement diminished the supply, spending had increased to $35 per year (there was no inflation in this period). The result was an illegal alcohol beverage industry that made an average of $3 billion per year in illegal untaxed income.
