The Madison Chatham Coalition was founded in 2015 as the result of a need identified by the existing municipal alliances; Madison Alliance Addressing Substance Abuse (MAASA) and the Municipal Alliance Committee of the Chathams (MACC). The Madison Health Department which serves Madison and the Chathams, identified that the three towns were struggling with similar substance abuse issues, mostly related to alcohol and marijuana, particularly in the 12-17-year old population. The Madison Health Department and municipal alliances believed it would be beneficial to combine prevention efforts to have a larger impact on reducing youth substance use. After discussing this with the county agency, Morris County Prevention is Key, the Madison Chatham Coalition became a Drug-Free Communities mentee coalition. In 2017, the Coalition was awarded the Drug-Free Communities federal grant which will help the Madison Chatham Coalition expand its reach and further reduce youth substance use in Madison and Chatham.
