Cannabigerol for Attention-Deficit/Hyperactivity Disorder (ADHD)

This study is looking at whether Cannabigerol (CBG) can help with symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD). Researchers want to see if a single dose of 80mg CBG reduces ADHD-related indicators compared to a placebo (an inactive substance). They will measure your attention and thinking skills using specific tests about 75 minutes after you take the CBG or placebo. You might be able to join if you are between 18 and 55 years old, have a certain body mass index (BMI), and meet specific criteria for ADHD symptoms. The study aims to enroll 76 participants, but its current status is unclear.
