Three wide-ranging reports describe what is known about treatment and prevention within diverse communities, including LGBT groups, disabled people and BME communities. The aim of the review was to encourage greater consideration of the needs and challenges of drug problems for minority groups, by bringing together a variety of evidence in one place. The study suggests that mainstream services are not always meeting the needs of diverse communities. The reports present challenges for commissioners of and practitioners within drug services, as well for the criminal justice system and wider drug policy makers.
