Planet Youth was introduced in the West of Ireland in 2018 and following a successful ethical approval process with the RCPI – Royal College of Physicians is being introcuded to North Dublin, along with Cavan and Monaghan in a research collaboration with the RCSI. There are currently three regional Drug & Alcohol Task Force areas in Ireland that are implementing Planet Youth. The Western Regional DATF ( Galway, Mayo and Roscommon), the North East Regional DATF in collaboration with the ETB(Cavan & Monaghan) and the North Dublin Regional DATF (North Dublin). These five-year pilot programmes have been initiated and developed in each area with a diverse range of partners in each of the regions. Each area has its own Steering Committee and substructures and these consist of funders and strategic and implementation partners, all of whom are committed to the development of Planet Youth to improve the health and wellbeing of young people in their areas. Planet Youth is an international evidence-based primary prevention model, developed by the Icelandic Centre for Social Research and Analysis (ICSRA) at Reykjavik University. It was initially developed in order to reduce substance use rates amongst young people. The model uses a whole population approach and offers the opportunity to improve health and life outcomes for young people in many areas. It works by directly targeting the risk and protective factors that determine their substance use behaviours and enhancing the social environment they are growing up in. By reducing the known risk factors and strengthening the known protective factors the problems associated with adolescent substance use can be reduced or stopped before they arise.
