Beer in the United States
On January 16, 1919, the Eighteenth Amendment to the United States Constitution was enacted into law, creating the Prohibition era, wherein the production, sale and transportation of alcoholic beverages was made illegal. All legal American brewing came to a halt when prohibition was imposed, though the earlier temperance movement had already reduced the number of breweries significantly. Only a few breweries, mainly the largest, were able to stay in business by manufacturing near beer, malt syrup, or other non-alcohol grain products, in addition to soft drinks such as colas and root beers. Production and shipping of alcohol was largely confined to illegal operations that could deliver compact distilled beverages—smuggled rum and domestic moonshine—more efficiently and reliably than bulkier products such as beer.
Prohibition in the United States
At the same time, songs emerged decrying the act. After Edward, Prince of Wales, returned to the United Kingdom following his tour of Canada in 1919, he recounted to his father, King George V, a ditty he had heard at a border town:
Prohibition became highly controversial among medical professionals, because alcohol was widely prescribed by the era's physicians for therapeutic purposes. Congress held hearings on the medicinal value of beer in 1921. Subsequently, physicians across the country lobbied for the repeal of Prohibition as it applied to medicinal liquors. From 1921 to 1930, doctors earned about $40 million for whiskey prescriptions.
