While overall alcohol consumption and alcohol-related automobile deaths have declined, rates of alcohol dependence, liver cirrhosis, and alcohol-related problems remain high among adults, and binge drinking continues as a major health risk for high school and college students. Some individual-level downstream interventions have been evaluated with sufficient rigor to recommend widespread dissemination, and widened availability of new pharmacotherapies could further increase effectiveness. Midstream population-based programs, such as screening and brief interventions in hospitals and managed care organizations, may have greater public health impact than tertiary treatment because of early identification and low cost. Upstream programs and policies that place limits on alcohol availability (e.g., higher legal purchasing age) have the greatest potential to reduce morbidity and mortality at the least cost to society.
