About the Survey

The Substance Abuse and Mental Health Services Administration (SAMHSA) conducts the annual National Survey on Drug Use and Health (NSDUH), a major source of information on substance use, abuse, and dependence among Americans 12 years and older. Survey respondents report whether they have used specific substances ever in their lives (lifetime), over the past year, and over the past month (also referred to as "current use"). Most analyses focus on past-month use.

National estimates on drug-related visits to hospital emergency departments (ED) are obtained from the Drug Abuse Warning Network (DAWN),1,2 a public health surveillance system managed by the Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Health and Human Services (HHS). DAWN data* are based on a national sample of general, non-Federal hospitals operating 24-hour Emergency Departments (EDs).
