What is cannabidiol?

The plant cannabis sativa contains over 70 different constituents, including tetrahydrocannabinol (THC) and cannabidiol (CBD), which are the most concentrated substances found in cannabis extracts. Recreational cannabis use during adolescence is a well documented risk factor for schizophrenia, particularly cannabis with high THC content. While THC induces symptoms in healthy volunteers that resemble psychosis, CBD interferes with the detrimental actions of THC in terms of psychotic proneness. Therefore, there is potential for CBD to act as an antipsychotic agent.

What is the evidence for cannabidiol?

Low quality evidence is unable to determine the benefits of cannabidiol for the symptoms of schizophrenia.
