Prohibition
Prohibition in the United States focused on the manufacture, transportation, and sale of alcoholic beverages; however, exceptions were made for medicinal and religious uses. Alcohol consumption was never illegal under federal law. Nationwide Prohibition did not begin in the United States until January 1920, when the Eighteenth Amendment to the U.S. Constitution went into effect. The 18th amendment was ratified in 1919, and was repealed in December 1933 with the ratification of the Twenty-first Amendment.
Pardon My Scotch
"Pardon My Scotch" was filmed on April 11-15, 1935, four months after the ratification of the Twenty-first Amendment to the United States Constitution which ended the American experiment with Prohibition. This event is an integral part of the storyline, with the drugstore owner (Al Thompson) frantically attempting to lay in a stock of liquor in anticipation of the imminent end of Prohibition.
