Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Cannabidiol (CBD) is another cannabis plant derivative for which, like THC, there has been extensive research. Unlike THC however, CBD is non-intoxicating and non-psychedelic. CBD has antipsychotic effects. Logically, if CBD opposes THC effects, it may be a potential antipsychotic treatment. The purpose of this pilot research is to show target engagement of the hippocampus with the study drug (CBD versus placebo) in patients who have been diagnosed with schizophrenia, schizoaffective disorder, or bipolar disorder with psychosis compared to healthy controls.
