Brain scans show how cannabis extract may help people with psychosis

Cannabidiol reduces the brain activity linked to hallucinations, delusions and other forms of psychosis, research has found

Brain scans have revealed for the first time how a substance found in cannabis plants may help people with psychotic disorders by dampening down abnormal brain activity that arises in the patients.

A single dose of cannabidiol, an non-intoxicating extract of the plant, reduced unusual patterns of neural behaviour linked to hallucinations, delusions, and other symptoms of psychosis, researchers found.
