The University of Kentucky recently received $3 million from the National Institute on Drug Abuse and National Institute on General Medical Sciences to fund new opioid-related research in the criminal justice system. Known as the Geographic variation in Addiction Treatment (GATE) study, the five-year project is led by Carrie Oser, professor of sociology in the UK College of Arts and Sciences. Oser and her colleagues will be focusing on the factors that influence a person’s decision to use one of the three FDA-approved medications for the treatment of opioid use disorder (OUD) — methadone, buprenorphine and extended-release naltrexone.
