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 The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Repeal of Prohibition in the United States
Specifically, "rates for cirrhosis of the liver fell by 50 percent early in Prohibition and recovered promptly after Repeal in 1933." Moore also found that contrary to popular opinion, "violent crime did not increase dramatically during Prohibition" and that organized crime "existed before and after" Prohibition. The historian Jack S. Blocker Jr. stated that "Death rates from cirrhosis and alcoholism, alcoholic psychosis hospital admissions, and drunkenness arrests all declined steeply during the latter years of the 1910s, when both the cultural and the legal climate were increasingly inhospitable to drink, and in the early years after National Prohibition went into effect." In addition, "once Prohibition became the law of the land, many citizens decided to obey it". During the Prohibition era, rates of absenteeism decreased from 10% to 3%. In Michigan, the Ford Motor Company documented "a decrease in absenteeism from 2,620 in April 1918 to 1,628 in May 1918."
