“Two major constituents of cannabis are Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the main psychoactive component; CBD may buffer the user against the harmful effects of THC.
We examined the effects of two strains of cannabis and placebo on the human brain’s resting-state networks using fMRI.
THC disrupts the DMN, and the PCC is a key brain region involved in the subjective experience of THC intoxication. CBD restores disruption of the salience network by THC, which may explain its potential to treat disorders of salience such as psychosis and addiction.”
“CBD in cannabis could reduce psychosis risk from high strength skunk, study shows. Buffer effect could point to a protective mechanism that may help ‘treat disorders like psychosis and addiction’. Cannabidiol (CBD), a chemical derived from the cannabis plant, can counteract the effects of high strength “skunk” strains and may help to reduce the risk of serious mental health conditions like psychosis, according to a new study.” https://www.independent.co.uk/news/health/cannabis-skunk-cbd-thc-psychosis-addiction-ucl-a8882991.html
