Cannabis medicines to treat ADHD appear to be moderately effective and can help patients focus, though it remains a debated form of medication for young patients.1
Studies have shown that ADHD may be caused by an underlying dysfunction of the dopamine transmitter system.2 There is a profusion of cannabinoid receptors in the areas of the brain associated with attention deficit (the amygdala and hippocampus), and the CB1 receptor seems to be an important therapeutic target. While there is limited data looking at CBD specifically, CBD’s anti-anxiety effects could conceivably be helpful to patients, and CBD might also be helpful for treating side effects like nausea that are often caused by prescription drugs.
