Prohibition in the United States - Doctors earn $40 million for whiskey

Prohibition in the United States was a nationwide constitutional ban on the sale, production, importation, and transportation of alcoholic beverages that remained in place from 1920 to 1933.

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.
