PET scan study to image cannabinoid receptors in the brain
Part of Mental health clinical trials.
This study uses a special brain scan (PET) to measure cannabinoid receptors—areas in the brain that interact with cannabis-like chemicals. It may help researchers better understand how these receptors relate to conditions such as schizophrenia, PTSD, opioid use disorder, or early psychosis risk.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be a male between 18 and 55 years old
- You must fit one study group: cannabis use, schizophrenia/schizoaffective, prodrome for psychosis, PTSD, or opioid use disorder
- If you’re in the cannabis group, you must be willing to stop all cannabis for 4 weeks before the scan
- You must have no metal or device in your body that could be unsafe for scanning (like certain metal or a pacemaker)
- You must not be claustrophobic (fear of enclosed spaces)

This study uses brain scans to understand opioid use disorder better. If you have opioid addiction, you might be eligible to help researchers learn more about how the brain is affected.
This study uses a special brain scan (PET) and MRI to look at how a protein in the brain, called CB1 (part of the body's natural pain and reward system), changes when people start treatment for opioid use disorder. It may help doctors understand how buprenorphine works and improve addiction treatments.
This study looks at how a specific type of brain receptor (dopamine-3) works in people with schizophrenia using special brain scans (PET). Researchers want to see how these receptors behave when you are not taking antipsychotic medication, which may help guide future treatments.
This early (Phase 1) study uses a special brain scan to look at synapses—the contact points between brain cells—in people with schizophrenia-related conditions. It helps researchers understand brain activity and connection patterns, which may guide future tests or treatments.
This study uses brain imaging to understand how thinking works in people who use cannabis, comparing those with psychosis to people without psychosis. It may help researchers learn what brain patterns relate to thinking difficulties and how cannabis use fits in.
This study looks at the brains of teenagers who use cannabis using an MRI scanner. It aims to understand how cannabis affects the developing brain, which might help improve treatment options.
