This is about the extract CBD, NOT THC or the whole plant….
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.
The impact of the substance has raised hopes that medical preparations of pure cannabidiol, or new drugs based on the compound, may be turned into effective treatments for young people who develop psychosis but do not respond to existing therapies.
While high strength cannabis is suspected of raising the risk of mental health problems in some frequent cannabis users, cannabidiol or CBD appears to have opposite, antipsychotic properties. In illicit cannabis, there is too little CBD to have much beneficial effect, but researchers have long wondered whether doses of pure CBD may help to protect against psychosis.
“We knew from previous studies that CBD had antipsychotic effects, but we didn’t know how it worked,” said Bhattacharyya.
