Study of MRI brain scans in cannabis smokers over time
Part of Mental health clinical trials.
This study follows people who currently or used to smoke cannabis to see how cannabis use may change certain MRI scan signals in the brain over time. You may help researchers understand the effects of cannabis smoking and how brain imaging changes can be measured safely.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 85 years old
- You currently smoke or used to smoke cannabis (with or without tobacco)
- You can sign consent and understand the study instructions
- You can do breathing tests (spirometry) that are consistent, with good lung function (FEV1 and FVC above set limits)
- You can hold your breath for about 16 seconds during the scan
- You can safely do an MRI: no metal/implants that can’t be removed, and you’re not severely claustrophobic

This study looks at how cannabis affects your lungs when you inhale it. It is for people who currently use both cannabis and tobacco and want to help researchers understand how these substances impact breathing and overall lung health.
This study looks at how a cannabis extract affects brain activity in healthy young adults who use cannabis occasionally. It uses brain scans to understand changes and may help guide future 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 compares people who smoke cannabis daily with people who have never used cannabis. It looks at how cannabis smoke affects lung stress and the lungs’ immune defenses, using health tests and urine screening to keep participants safe.
This Phase 1 study tests how inhaled THC and a natural plant chemical called myrcene affect behavior, thinking, and safety in healthy adults. You may help researchers understand potential brain/behavior effects before larger studies.
