This report presents the results of Australian Institute of Criminology (AIC) research on issues and challenges of policing alcohol and illicit drug use among Aboriginal and Torres Strait Islander people in metropolitan environments. This report is a companion to the 2006 National Drug Law Enforcement Research Fund (NDLERF) project, The policing implications of cannabis, amphetamine and other illicit drug use in Aboriginal and Torres Strait Islander communities (Delahunty and Putt 2006b). The main purpose of both pieces of research was to contribute to police service knowledge of substance use by Indigenous people and to provide a framework for good practice policing of the issues associated with alcohol and drug misuse.
