Summary
This study follows 180 adults aged 30–75 with chronic pain who are prescribed medical cannabis. Researchers test memory, attention, and problem-solving skills, and use brain scans to see how cannabis compounds affect brain structure and activity. Participants are tracked for four months to compare the effects of CBD-dominant versus THC-dominant products.
