Success story about 10 mental health treatment facilities in Connecticut and Massachusetts that tested out a new Approach to Addressing Tobacco Use Through Organizational Change (ATTOC) – a 10-step process designed to help organizations change their culture and systematically improve their tobacco addiction treatment for clients and staff through staff training, improvement of clinical services, and program development. As a result of the initiative, 7 of the 10 facilities testing ATTOC established tobacco-free grounds.
