We conduct and support substance use research to inform evidence-based care and improve patient health and treatment outcomes. In addition to providing data and guidance to CODA, the program publishes in peer-reviewed journals, presents at national and international conferences, and participates in federally and privately funded research.

CODA research

CODA’s nationally recognized Research Program has randomized over 2,000 study participants in 20 funded trials. We have collaborated with Oregon Health & Science University (OHSU), Geisel School of Medicine at Dartmouth College, University of Pittsburgh, University of Washington, Virginia Commonwealth University, Kaiser Permanente, and other institutions on research funded by the National Institute on Drug Abuse (NIDA), National Institute on Alcohol Abuse and Alcoholism (NIAAA), and other foundations and companies. Earlier clinical trials examined the use of extended-release naltrexone and buprenorphine, leading CODA to be early adopters of these FDA-approved medications for opioid use disorders.

Current studies

UPDATE: The CODA Methamphetamine Use Disorder Study (Accelerated Development of Additive Pharmacotherapy for the Treatment of Methamphetamine Use Disorder — ADAPT-2) is now closed to recruitment. Thank you to all who contacted us concerning this important work. CODA has recently been awarded the opportunity to participate in two new trials. One is starting later this Spring and one this Fall.  Please check back here for more information.
