New study: CBD diminishes THC-associated impairment


In a new study from the University College London (UCL), a group of researchers focused on the distinction amongst consuming cannabis strains that have higher levels of THC, and strains that have important quantities of each THC and CBD.

The precise effects on the brain have been monitored by an fMRI (functional magnetic resonance imaging), which measures alterations in blood flow and neural activity.

Brain scans of the 17 participants showed that the higher-THC strain impaired the functionality of the default mode network, in particular in the posterior cingulate location.

The dysfunctionality of the posterior cingulate location closely corresponded with the sensation of “getting higher”, displaying that the effects of THC on this section are connected with the cerebral intoxication of cannabis.

The higher-THC strain also brought on disruption to the salience network, which determines what sensory or emotional facts we concentrate on at a offered time.

Improper functioning of the salience network was currently connected with psychosis and addiction prior to this study.

In contrast to the strain which only contained higher levels of THC, the strain that also had higher levels of CBD brought on minimal disturbances to these regions of the brain.

The outcomes of this study assistance the theory that the CBD cannabinoid (when made use of in mixture with THC) diminishes the adverse effects of THC, like the psychoactivity brought on by tetrahydrocannabinol, even though adding to the medicinally advantageous effects.

Dr. Matt Wall (the major author of the study), comments:

“Over the final two decades, prices of addiction and psychosis linked to cannabis have been on the rise, even though at the similar time stronger strains of cannabis with additional THC and significantly less CBD have come to be increasingly popular.

“We have now discovered that CBD seems to buffer the user against some of the acute effects of THC on the brain.”
