The Drug Abuse Warning Network (DAWN) is a nationally representative public health surveillance system that continuously monitors hospital drug-related ED visits. DAWN uses a probability sample of hospitals to annually produce estimates of drug-related ED visits for the United States and selected metropolitan areas. Any ED visit related to recent drug use is included in DAWN and all types of drugs (licit and illicit) are covered, including all alcohol involvement in patients under age 21 and alcohol involvement in combination with other substances in those age 21 and older.

The Substance Abuse and Mental Health Services Administration (SAMHSA), U.S. Department of Health and Human Services (HHS) is the agency responsible for DAWN.

The 2006 through 2009 DAWN public-use data and documentation files are also available on the SAMHDA Web site for download and online analysis. SAMHDA plans to release the 2010 DAWN in the upcoming weeks.
