There is growing emphasis in public policy on involving young people in the development of health promotion campaigns and information resources on substance misuse. To date there has been little literature that explores the level and nature young people's involvement in such initiatives. This paper reports on an evaluation of a substance misuse communications campaign that sought to involve young people in the project process and the production of locally focused media products. The findings from this study indicate potential benefits in terms of the production of credible and locally appropriate messages on substance misuse. It also found that there were wider benefits associated with the promotion of young people's citizenship and participation in local service delivery. Young people's involvement needs to be understood as part of a process across a range of different types of activities. Participation by young people vulnerable to substance misuse may contribute to agendas on inclusion and targeted welfare, however it requires a high level of commitment by local agencies and strategic authorities. The key to realizing young people's potential is the use of experienced facilitators, well-informed advisors and dedicated media experts who can work alongside young people in a range of settings within their communities.
