CTN Pacific Northwest Node
The Pacific Northwest Node joined the National Drug Abuse Treatment Clinical Trials Network in January 2001, with the goal of forging partnerships to improve the quality of substance use disorder treatment and improve the lives of people affected by substance use in our region and throughout the nation. The Node is a collaboration among researchers at the University of Washington Addictions, Drug & Alcohol Institute and Washington State University, as well as affiliated community partners across Washington, California, and Alaska.
The Pacific Northwest Node is also the home of the CTN Dissemination Library, a digital library of journal articles and other publications created by and about the work of the NIDA CTN.
