The California/Arizona Node joined the Clinical Trials Network in September 2002. Participating CTPs, several of which have multiple sites, include hospital-based and community-based programs, and include residential, outpatient, and methadone treatment approaches. Collectively, these CTPs serve a racially and ethnically diverse population of more than 16,000 patients per year.

The California/Arizona Node combined with the Oregon/Hawaii Node in 2010 to form the Western States Node.
