Justipedia explains Prohibition
In the United States, prohibition was enforced through the United States Constitution. Specifically, the Eighteenth Amendment of the United States Constitution completely banned alcohol from entering into the United States. During the time of prohibition, there was a great push to make the public aware of addictive illnesses. During this time period, the government took a progressive approach on trying to cure these addictive illnesses such as alcoholism. However, on December 5, 1933, the United States repealed the Eighteenth Amendment.
