Prohibition in the United States
Research shows that prohibition reduced overall alcohol consumption by half during the 1920s, and consumption remained below pre-Prohibition levels until the 1940s, suggesting that Prohibition did socialize a significant proportion of the population in temperate habits, at least temporarily. Rates of liver cirrhosis "fell by 50% early in Prohibition and recovered promptly after Repeal in 1933." Criticism remains that Prohibition led to unintended consequences such as a century of Prohibition-influenced legislation and the growth of urban crime organizations, though some scholars have argued that violent crime did not increase dramatically, while others have argued that crime during the Prohibition era was properly attributed to increased urbanization, rather than the criminalization of alcohol use. As an experiment it lost supporters every year, and lost tax revenue that governments needed when the Great Depression began in 1929.
Prohibition
After several years, prohibition failed in North America and elsewhere. Rum-running or bootlegging became widespread, and organized crime took control of the distribution of alcohol. Distilleries and breweries in Canada, Mexico and the Caribbean flourished as their products were either consumed by visiting Americans or illegally exported to the United States. Chicago became notorious as a haven for prohibition dodgers during the time known as the Roaring Twenties. Prohibition generally came to an end in the late 1920s or early 1930s in most of North America and Europe, although a few locations continued prohibition for many more years.
