This study aims to develop a better tool for recalling and tracking opioid use patterns, especially with fentanyl. It may help people who use opioids outside of medical settings to more accurately report their use.
Baltimore, MarylandAges 18–99 - NCT05408247RecruitingPhase 4
N-acetylcysteine to help people cut back on alcohol
This trial tests whether N-acetylcysteine (a supplement-like medicine) can help people with alcohol use disorder reduce or stop drinking. You may be randomly assigned to receive N-acetylcysteine or a comparison treatment, and you’ll complete interviews during the study.
Sydney, New South WalesAges 18–70 - NCT05995769RecruitingPhase 2
Psilocybin therapy with talk therapy for alcohol problems
This trial tests whether psilocybin (the active ingredient in magic mushrooms), given with talk therapy, can help people who want to reduce their heavy drinking. It is for people with at least moderate alcohol use disorder who are motivated to change.
Calgary, AlbertaAges 22–65 - NCT07829263Recruiting
Brain stimulation with talk therapy for cocaine use disorder
This study tests whether a non-invasive brain stimulation method (high-definition transcranial direct current stimulation, or HD-tDCS) combined with cognitive behavioral therapy (a type of talk therapy) can help people reduce cocaine use. It explores if this combination is safe and practical.
Richmond, VirginiaAges 18–65 - 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 - NCT07665502Enrolling by invitation
Smartphone app to boost opioid treatment for women facing violence
This study tests a smartphone app (WINGS+++) to help women who have experienced intimate partner violence and trauma improve their engagement with medication for opioid use disorder (MOUD). The goal is to see if the app makes it easier to start and stay on treatment.
New York, New YorkAges 18 years+ - NCT07654205Recruiting
Smartphone intervention for young adults with ADHD and heavy drinking

New Haven, ConnecticutAges 21–60 - 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 - NCT07464613Recruiting
Social thinking in severe alcohol use disorder
This study looks at how people with severe alcohol use disorder process social information, like understanding others' emotions or intentions. It uses brain imaging (MRI) and tests on a smartphone. The goal is to learn more about social cognition in recovery.
Reims, ReimsAges 18–65 - NCT05997212Recruiting
Can brain stimulation help with thinking skills in alcohol use disorder?
This study tests if a noninvasive brain stimulation technique called repetitive TMS (rTMS) can improve thinking skills like decision-making and focus in people recovering from alcohol use disorder. You must have been alcohol-free for 8 weeks to 5 years.

- How do I know if I qualify for a substance use disorders trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a substance use disorders trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
