Prohibition Party
The Prohibition Party's proudest moment came in 1919, with the passage of the 18th Amendment to the United States Constitution, which outlawed the production, sale, transportation, import and export of alcohol. The era during which alcohol was illegal in the United States is known as "Prohibition".
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.
