The Orthodox Christian Coalition for Healthy Youth (or OCCHY)  is a unique national alliance founded and supported by the Department of Youth and Parish Ministries  of the Antiochian Archdiocese, involved in establishing, training and leading substance abuse prevention and intervention coalitions across America. The Healthy Youth initiative, sponsored by OCCHY, offers communities an opportunity to heighten awareness of how to combat substance abuse, prevent bullying, encourage sexual abstinence outside of marriage, and encourage respect for the sanctity of the human body. Recent updates on the Hookah Prevention initiative, the Healthy Youth ministry of Tucson, AZ, and the Cicero/Chicago based group, are available on OCCHY's Website. 
OCCHY is developing local community networks to address substance abuse prevention and healthy living in parishes of each diocese. Each local chapter is trained in coalition building in their community. Chairman of the Department of Youth and Parish Ministries Fr. Joseph Purpura, and Kh. Kathleen Purpura, Youth Consultant and Executive Director of OCCHY, work with the White House Director of the Drug Free Communities Program, the Substance Abuse and Mental Health Services Administration (SAMHSA), the staff of the Community Anti-Drug Coalitions of America (CADCA), and local coalition leaders to establish substance prevention coalitions across America.
