In early 1920, Stone helped organize the enforcement machinery in the District of Columbia, Maryland, Ohio, and West Virginia, and supervised enforcement efforts in Alabama, Florida, Georgia, Michigan, New York, and Tennessee. From 1920 to 1921, Stone served as a Prohibition Unit enforcement agent, chief of the enforcement division for the District of Maryland and Ohio, and supervising national prohibition agent His position as supervising agent was abolished in 1921, and he was placed in charge of the Atlanta division of the Income Tax Unit. Stone remained in that position at least until 1924. When mass corruption was uncovered in the Wisconsin district in 1924, Stone left Atlanta and was appointed Acting Director of Prohibition for the state, where he remained at least until the end of the year.

Congress reorganized Prohibition enforcement efforts on March 3, 1927, with the Bureau of Prohibition Act. The act established a new Bureau of Prohibition in the Department of the Treasury, to be overseen by the existing Commissioner of Prohibition. As part of this reorganization, an enforcement district covering just the state of Michigan was created. Stone was appointed administrator for Michigan and for a time took up residence in the city of Detroit. In 1928, Stone spent $400,000 on
