An economist named michael andrews, who pulls data on wet and dry counties during prohibition. And i think he was able to show pretty conclusively that the number of new s were reduced by 15 % annually in counties that went from wet to dry in the early years the prohibition. E noted, people didn't stop drinking. They went near they turnd to boot leg liquor, or they made stuff at home. But what they couldn't do any more is go to saloons and talk over alcohol.
