The recipient proposes to develop training materials on screening for substance use and assessment and treatment strategies that will meet the needs of community partners who engage with youth who are involved in the justice system. The training materials will be developed by a team that will consist of an addictions clinical consultant, a youth justice consultant, a youth engagement and community development consultant and young people who have been involved with the youth justice system. The team will establish a network of community justice partners, affiliated community partners and youth. A review of best practices and other evidence-based materials will also be conducted. Community partners and youth will then assist in the design and testing of the training materials to ensure they meet community needs.
