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 The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Tequilero
The term "tequilero" also refers to Mexicans who helped to smuggle alcohol into the United States during the Era of Prohibition from 1920 to 1933, a time when the United States outlawed the sale, manufacture, and transportation of non-religious alcohol.
