People suffering from Parkinson's disease have a high rate of psychosis, which may be induced or worsened by drugs used to treat the illness. A recently published study in the Journal of Psychopharmacology suggests that a marijuana component called cannabidiol (CBD) may be a helpful treatment for this condition.
This was a small, uncontrolled pilot study, but CBD produced rapid and fairly dramatic reductions in psychotic symptoms. And the growing body of evidence regarding CBD's anti-psychotic properties has important implications beyond Parkinson's patients. For example, there is some evidence that THC can worsen psychotic symptoms, but at least one study has implied that CBD, if present in sufficient quantities, can counter this effect.
