Helping young adults stop opioids after an emergency visit
This study offers an engagement program for young people who tested positive for opioids and meet criteria for opioid dependence. The goal is to help participants stop opioid use safely and learn whether this approach works well in the real-world emergency setting.
Houston, TexasAges 13–17 - NCT06218706Recruiting
Focused ultrasound for severe opioid addiction
This trial uses focused ultrasound (sound waves aimed at a specific part of the brain) to help people who have severe opioid addiction that hasn't gotten better with other treatments. It may help reduce cravings and support recovery.
Morgantown, West VirginiaAges 22–60 - NCT06207162Recruiting
Brain scans and methadone treatment for opioid recovery
This study uses MRI scans over time to track brain changes in people with opioid use disorder who recently started methadone treatment. You can help researchers understand recovery patterns if you are early in your methadone journey and can commit to repeated visits.
New Haven, ConnecticutAges 18–50 - NCT06160284RecruitingPhase 1
Psilocybin for brain healing in opioid recovery
This study tests whether psilocybin, a psychedelic substance, can help change brain connections in people recovering from opioid use disorder. It involves brain scans and careful medical monitoring to explore new treatment options.
New Haven, ConnecticutAges 25–55 - NCT06157840Recruiting
Sleep program for people on buprenorphine treatment
