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 - NCT06103370Recruiting
HIV prevention via telemedicine and peer networks
This study tests how well a program combining telemedicine (virtual doctor visits) and peer support can help prevent HIV among people who inject drugs. You'd get trained, attend weekly group sessions, and invite a friend or partner to also take part.
Baltimore, MarylandAges 18 years+ - NCT05829655RecruitingEarly Phase 1
Measuring drug cravings in people with opioid use disorder
This study tests whether the medication suvorexant can reduce drug cravings in people with opioid use disorder. You will take either suvorexant or a placebo and have your cravings measured in a safe setting.
Baltimore, MarylandAges 18–65 - NCT05807139RecruitingPhase 1
Spironolactone for alcohol use disorder
This Phase 1 study tests whether spironolactone (a medicine that affects salt and hormone balance) is safe and potentially helpful in people with alcohol use disorder. You may be eligible if you are currently drinking heavily, have low alcohol withdrawal symptoms, and meet several lab and medication safety rules.
Baltimore, MarylandAges 21–99 - NCT04998916Recruiting
Brain stimulation to reduce heavy drinking in alcohol use disorder
This trial tests a type of noninvasive brain stimulation to see if it can reduce drinking and related “wanting” to drink. It may help people with alcohol use disorder who are currently drinking heavily.
Charleston, South CarolinaAges 21–65 - NCT04197921Recruiting
Brain-focused ultrasound for opioid addiction-related substance use
This trial studies Exablate, a non-surgical brain treatment that aims to change activity in a specific brain area involved in cravings and substance use. It is meant for people in structured opioid or substance use treatment who are currently abstaining from opioids and other illicit drugs.
Tampa, FloridaAges 18–60 - NCT04141202Recruiting
Exercise program during short inpatient treatment for substance use
This trial tests a structured exercise program for people receiving short-term inpatient treatment for substance use. It may help improve health and recovery support during your stay.
TrondheimAges 18 years+ - NCT05899660Recruiting
Omega-3 for alcohol use disorder during withdrawal
This trial studies whether taking omega-3 supplements during a hospital alcohol-withdrawal program can improve recovery for people with alcohol use disorder. It may help by changing inflammation and how the body responds to stopping alcohol.
BrusselsAges 18–70 - NCT07825818RecruitingEarly Phase 1
Brain scan study for heavy drinkers
This study uses a special brain scan to look at how alcohol use affects energy production in brain cells. It may help researchers find new ways to treat alcohol use disorder.
Pittsburgh, PennsylvaniaAges 18–55 - NCT07612631RecruitingEarly Phase 1
Brain imaging study of alcohol and stress response
This research uses brain imaging to understand how two brain systems—one involved in stress and one involved in reward—interact in people with alcohol use disorder. The goal is to find new ways to help people reduce heavy drinking.
Pittsburgh, PennsylvaniaAges 18–55 - NCT07490600Recruiting
Testing brain stimulation and rewards for quitting cocaine
This trial combines deep transcranial magnetic stimulation (TMS) with a reward program (contingency management) to help people stop using cocaine. It may help if you are struggling with moderate to severe cocaine use and want a non-drug treatment.
Houston, TexasAges 18–65 - NCT07325266RecruitingPhase 2

Los Angeles, CaliforniaAges 21 years+ - NCT06870110Recruiting
Brain training for opioid use disorder
This trial tests a brain-training program for people with opioid use disorder. It uses an EEG headset to measure brain activity while you do computer exercises, and aims to see if this training can help recovery.
Minneapolis, MinnesotaAges 18–65 - NCT07313371RecruitingPhase 4
Clonidine for reducing cravings in cocaine and crack users
This trial tests whether the medication clonidine can help reduce cravings for people hospitalized with cocaine or crack use disorder. You must be staying in a specific hospital ward and be able to take pills by mouth.
