Willis–Campbell Act

The Willis–Campbell Act of 1921, sponsored by Sen. Frank B. Willis (R) of Ohio and Rep. Philip P. Campbell (R) of Kansas, specified that only "spirituous and vinous liquors" (i.e. spirits and wine, thus excluding beer) could be prescribed medicinally, reduced the maximum amount of alcohol per prescription to half a pint, and limited doctors to 100 prescriptions for alcohol per 90-day period. It was commonly known as the "beer emergency bill".[1][2]

The Act kept in force all anti-liquor tax laws that had been in place prior to the passage of the Volstead Act in 1919, giving authorities the right to choose whether or not to prosecute offenders under prohibition laws or revenue laws, but at the same time guaranteeing bootleggers that they would not be prosecuted in both ways.
