Since 1992, CADCA has demonstrated that when all sectors of a community come together, social change happens. CADCA represents over 5,000 community coalitions that involve individuals from key sectors including schools, law enforcement, youth, parents, healthcare, media and others. We have members in every U.S. state and territory and more than 30 countries around the world. The CADCA coalition model emphasizes the power of community coalitions to prevent substance misuse through collaborative community efforts. We believe that prevention of substance use and misuse before it starts is the most effective and cost-efficient way to reduce substance use and its associated costs.
