The Pacific Northwest Node (formerly the "Washington Node") joined the CTN in January 2001, and includes Washington and Alaska, with dissemination partners in Nevada and Oregon. Its CTPs provide a mix of settings including: urban and rural, private and public sector, in-patient/residential and outpatient, and drug free and methadone maintenance programs. The CTPs provide a wide range of treatment services to nearly 12,000 clients per year. All available services are also targeted to specific groups having special needs such as women, the elderly, Native Americans and Alaska Natives, dual disorder clients, homeless populations, and adolescent clients.

In 2010, the Pacific Northwest Node added several Dissemination Partners:
