Note: In order to better serve the residents of Nassau County, this Agency is being merged into:
"Mental Health, Chemical Dependency and Developmental Disabilitites Services"

Welcome to the Nassau County Department of Drug and Alcohol Addiction (NCDDAA).  The department serves the citizens of Nassau County in many ways by targeting issues of chemical abuse, promoting healthy behaviors, and attempting to prevent the start of deleterious actions in our children and youth.  Many services are provided directly by the department while others are a result of collaborations with other health and human service agencies, sub-contracts with community and hospital-based agencies, and school prevention programs.

We hope that as you browse through this website, you’ll find it informative and helpful.  We’ve provided information on drugs of abuse, department newsletters, crisis contacts, frequently asked questions, and links to many other sites that will give you additional information about the addiction field and the services that are available.  Our staff of professionals is here to assist you with any questions you may have.
