We are proud to announce the return of the COD Conference.
Join us October 4–6, 2026 for three days of shared learning, emerging research, and meaningful connection around co-occurring disorders.
This year carries special significance as we mark the 40th anniversary of the Co-Occurring Conference — a milestone that reflects decades of dedication from clinicians, researchers, advocates, and the communities we serve together.
