Eighteenth Amendment to the United States Constitution. The Eighteenth Amendment (Amendment XVIII) of the United States Constitution effectively established the prohibition of alcoholic beverages in the United States by declaring the production, transport, and sale of alcohol (though not the consumption or private possession) illegal.
Prohibition in the United States was a nationwide constitutional ban on the sale, production, importation, and transportation of alcoholic beverages that remained in place from 1920 to 1933.ost economists during the early 20th century were in favor for the enactment of the Eighteenth Amendment. Simon Patten, one of the leading advocates for prohibition, predicted that prohibition would eventually happen in the United States for competitive and evolutionary reasons.
