By 1916, over half of the U.S. states already had statutes that prohibited alcohol. In 1919, the 18th Amendment to the U.S. Constitution, which prohibited the sale and manufacture of alcohol, was ratified. It went into effect on January 16, 1920.
For instance, the 18th Amendment did not mention the actual drinking of liquor. Since Prohibition went into effect a full year after the 18th Amendment's ratification, many people bought cases of then-legal alcohol and stored them for personal use.
