This briefing reviews the changes that are occurring to services for young people at the local level in the UK and considers the potential impact of these for drug problems. It draws on interviews with 27 people working in a range of different types of young people’s services in nine local case study areas, a one-day event attended by people from statutory and voluntary organisations working with young people, as well as relevant published reports. The main focus of this report is on services for adolescents, generally those under 18, which tends to be the threshold for transition into adult services.
