How cannabis affects the aging brain
Treatments studied
Part of Brain & nervous system clinical trials.
This study uses brain scans (fMRI) to see how THC (the active ingredient in cannabis) affects the brain as people age. If you are a cannabis user without current dependence or health issues, you may help researchers understand these effects.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have used cannabis (marijuana) in the past 2 years and felt 'high' at least once.
- You are comfortable reading and speaking English.
- You do not currently have problems with cannabis use, like strong cravings or trying to quit.
- You have never had a bad reaction to cannabis.

This study tests whether THC, the active compound in cannabis, changes how the brain processes information during memory tasks. It uses brain scans (MEG and EEG) to see these effects in healthy adults who have used cannabis before.
This study tests different ratios of CBD to THC to see how CBD can change the effects of THC. It may help people who use cannabis occasionally understand how CBD can reduce unwanted side effects.
This trial studies how a single dose of THC (the active ingredient in cannabis) affects older adults. It aims to understand the effects in this age group, which may help guide safe use.
This early study measures how a THC dose (by mouth or vaporized form) moves through the body and how it affects the body’s responses. It mainly looks at safety and how THC behaves in older adults, including people who have used cannabis before.
This early-stage study compares how people in different age groups respond to THC taken by smoking versus by mouth. It aims to understand age-related differences in effects and safety, which could help guide safer use in the future.
This study looks at how cannabis affects thinking and mood. If you join, you'll have a session where you use cannabis and then do some thinking and mood tasks, to see how it affects you.
