Based on combined data from the 2002–2004 National Surveys on Drug Use and Health, it is estimated that 7.6% (18.2 million) of persons age 12 years or older met the criteria for alcohol dependence or abuse in the past year. Data from the national Epidemiologic Catchment Area (ECA) study of the late 1980s indicate that lifetime prevalence of alcohol dependence is as high as 14.7% (Regier et al. 1990). Estimates of financial impact from loss of productivity due to alcohol-related illness, premature deaths, and alcohol-related crimes are greater than $134 million per year (U.S. Department of Health and Human Services 2000).
