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
Heavy drinkers and alcoholics were among the most affected groups during Prohibition. Those who were determined to find liquor could still do so, but those who saw their drinking habits as destructive typically had difficulty in finding the help they sought. Self-help societies had withered away along with the alcohol industry. In 1935 a new self-help group called Alcoholics Anonymous (AA) was founded.
