The Demand Treatment! project includes nationwide support to help drive up the demand for brief interventions and treatment by using the World Wide Web, as well as a City Partners initiative to support teams from up to 12 cities as they implement strategies to increase the demand for treatment in their communities. In the fall of 2001, Demand Treatment! will host regional conferences in Maryland, California, Texas, and Missouri to explore ways communities can drive up demand for substance abuse treatment. Further, the project will develop and share extensive new Web resources that will help individuals and their families understand and act on their own drug and alcohol problems. Additional web-based information and tools will also be developed to help employers, health care professionals, providers, and other community institutions implement more effective alcohol and drug treatment policies and practices. This paper outlines the reasons why the project was established, describes the nature of the regional conferences and how to register for them, provides guidelines for becoming a project city partner, and gives details on using Web resources. 13 resources and a conference registration form
