The Alcohol Research Group (ARG) has been engaged in epidemiological studies of alcohol and health services research since 1959. ARG is the home of one of sixteen National Alcohol Research Centers funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). While the majority of ARG grants are funded by NIAAA, other grants have been awarded from the National Institute on Drug Abuse, the National Institute for Mental Health, the Centers for Disease Control, the Center for Substance Abuse Treatment, and the Robert Wood Johnson Foundation. Current research focuses on alcohol and drug use and related problems, health services research, policy analysis, and the study of community responses and interventions. Groups studied include the general population and specific populations, such as individuals in treatment, welfare recipients, pregnant women, emergency room patients, and homeless persons.
