Drug Misuse: Most States Have Good Samaritan Laws and Research Indicates They May Have Positive Effects, Report to Congressional Committees [open pdf - 2MB]
From the GAO (Government Accountability) Highlights: "Since 1999, more than 800,000 people have died from a drug overdose in the United States, with over 86,000 occurring during the 12-month period ending in July 2020, according to the most recent provisional data available from the Centers for Disease Control and Prevention's National Center for Health Statistics. In recent years, some states have enacted Good Samaritan and Naloxone Access laws to help reduce overdose deaths and respond to opioid overdoses. The Comprehensive Addiction and Recovery Act of 2016 included a provision for GAO to review these laws. This report addresses the following: (1) the efforts ONDCP [Office of National Drug Control Policy] has taken to collect and disseminate information on Good Samaritan and Naloxone Access laws, (2) the extent to which states, territories, and D.C. have these laws and the characteristics of them, and (3) what research indicates concerning the effects of Good Samaritan laws."
