Changes in access to and availability of alcohol in the United States: research and policy implications.

Recent changes in alcohol availability and access in the United States are reviewed and the role public policy research played in such changes are discussed. The paper finds that there are two concurrent trends, i.e. increased alcohol availability through changes in wine and spirits structural availability, lower prices and increased outlet densities, and decreased availability and access through higher minimum drinking ages, server intervention and training, server liability, low- and no-alcohol beverages, and warning labels on alcohol containers. This paper discusses these trends and the implications for policy development to which research is an input.
