The Harris Project, started in 2013 at Stephanie’s kitchen table, empowers youth to make positive decisions through an understanding of paths to substance misuse and addiction such as mental health challenges, sports injury, wisdom tooth removal and, supports the creation of best practices in early identification and intervention. the Harris Project’s CODA movement (Co-Occurring Disorders Awareness) is a youth-led effort to create a community culture built on caring and compassion. Together Graham and Stephanie discuss the challenges of co-occurring disorders and the unique ways the Harris Project and the CODA movement are addressing the needs and providing resources for young people in an effort of prevention.
