Recruiting studies
- NCT04972136Recruiting
Brain stimulation treatment for depression in young adults with autism
This trial studies a noninvasive brain stimulation (rTMS) to help reduce depression symptoms in young adults who have autism. It aims to find out if this treatment can improve mood and daily functioning without requiring recent changes to medications.
Toronto, OntarioAges 16–35 - NCT04812613Enrolling by invitation
Study of cannabis use and mental health support for Ottawa youth
This study looks at tobacco use alongside other addictions in young people in Ottawa who have unstable housing and mental health concerns, and who use cannabis or have used it before. It may offer support or new approaches aimed at reducing health risks related to tobacco and substance use.
Ottawa, OntarioAges 16 years+ - NCT04613791Recruiting
Alcohol and addictive behaviors in people with obesity
This study looks at how often people with obesity struggle with alcohol or other addictive behaviors, and how these issues change over time. Understanding this connection may help doctors better support patients managing obesity.
NîmesAges 18 years+ - NCT04379115Recruiting
Brain stimulation study for people with opioid addiction
This study tests a non-invasive brain stimulation approach to reduce opioid cravings in people who are actively using non-prescribed opioids while on stable methadone. It may help people feel less craving and improve recovery support.
Hinsdale, IllinoisAges 18–85 - NCT04478838RecruitingPhase 4
Alternate-day antipsychotic dosing for schizophrenia
This trial looks at whether taking an antipsychotic every other day can keep symptoms controlled in adults with schizophrenia or another psychotic disorder. It may help some people avoid daily dosing, but it requires specific medication stability and screening checks.
Toronto, OntarioAges 18 years+ - NCT04325958Recruiting
Test how cannabis affects driving in different age groups
This study looks at how smoked cannabis changes driving performance when compared across two age groups. It may help researchers understand safety risks and differences by age.
Toronto, OntarioAges 19–45 - NCT04356274Enrolling by invitation
Improving access to addiction and mental health care at VA clinics
This study tests an approach to help VA clinics reach more Veterans with proven treatments for addiction and mental health conditions. It focuses on clinic-level processes (not individual medications) to increase how widely evidence-based care is delivered.
Palo Alto, CaliforniaAges 18 years+ - NCT02535702Recruiting
Brain scan study to measure addiction biology
This study uses brain imaging (MRI) and tasks to better understand what’s happening in the brain in addiction. It may help researchers improve how addiction is studied and measured using brain-based methods.
Bethesda, MarylandAges 18 years+ - NCT02639702RecruitingPhase 4
Switching from twice-daily to once-daily clozapine for schizophrenia
This trial tests whether taking clozapine once a day (instead of twice a day) works safely for people with schizophrenia. It may help by simplifying your dosing schedule while closely monitoring your wellbeing.

- How do I know if I qualify for a addiction 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 addiction 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.
