This report describes and evaluates four projects within the Partnership Drugs Initiative. Two of the projects are designed to intervene with young people who are engaged in substance misuse, one provides support for young carers from families in which a parent is misusing drugs or alcohol and one seeks to reduce the impact of parents’ drug use upon their children. The purpose of the report is 1) to describe and assess the impact of the four projects upon their various client groups and 2) to review what we can learn from them.
