[1] DAWN was discontinued in 2011,[1] but its creator, the Substance Abuse and Mental Health Services Administration (SAMHSA), continues to develop other sources of data on drug-related emergency visits.
All data are collected through a retrospective review of patient medical records and decedent case files.
[5] SAMHSA has contracted with Westat, a private research corporation, to manage the New DAWN on the agency's behalf.
A report released by DAWN in 2002 [9] claims that marijuana overdose alone resulted in documented deaths in Atlanta and Boston, respectively.
However, there is no known record or evidence to support the existence of a case of human fatality by result of marijuana overdose.
