"A five-year national study by researchers at UF and the University of Minnesota found regular police checks of businesses that sell alcohol strongly deter alcohol sales to minors and are far more effective than programs that simply train bar and restaurant staff to identify minors and refuse them alcohol.
The study, published in the March issue of Addiction, included 942 establishments that sold alcohol in 20 Midwestern U.S. cities."
