Cannabis, brain waves, and attention study
Treatments studied
Part of Mental health clinical trials.
This study looks at how cannabis use affects brain activity and attention. It compares heavy users and non-users to understand the effects on memory and focus.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 21 and 40 years old
- You are right-handed
- You are either a heavy cannabis user (using at least 4 days per month for a year) or a non-user (no cannabis for 6 months but have tried it at least once)
- You have not used other recreational drugs (like cocaine, MDMA, or non-prescribed sedatives) in the past 30 days
- You are not a regular nicotine user (using 4 or fewer days per week) and can avoid caffeine and nicotine for 4 hours before appointments
- You are not pregnant, not in treatment for substance use or certain mental health disorders, and not taking psychotropic medications (some antidepressants, anti-anxiety, and ADHD meds are okay with adjustments)

Other trials that look related to this one.
This Phase 2 study looks at how THC (from cannabis) changes brain signals during working memory tasks. It uses EEG and MEG (noninvasive brain recording) to understand changes in “neural noise” and how well information moves through memory networks.
This study looks at how a single session of exercise affects brain function and memory in regular cannabis users compared to non-users. You will exercise on a bike or watch a movie, and then do memory tests and a blood draw.
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 early-stage study tests whether THC and CBD affect memory in people who have used marijuana only occasionally in the last year. You may be asked to complete memory-related tasks and screening tests, including a urine test and an MRI scan if you can safely have one.
This trial tests whether a treatment called repetitive transcranial magnetic stimulation (a non-surgical magnetic stimulation to the brain) can help people reduce or stop cannabis use. You may be eligible if you have cannabis use disorder and meet specific safety and symptom criteria.
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.
