Study suggests high levels of skunk use may affect the brains white matter, attaining communication between the right and left hemispheres less efficient
High-strength cannabis may injury nerve fibers that handle the flow of messages across the two halves of the brain, scientists claim. Brain scans of people who regularly smoked strong skunk-like cannabis revealed subtle differences in the white matter that connects the left and right hemispheres and carries signals from one side of the brain to the other.
The changes were not seen in those who never employed cannabis or smoked only the less potent forms of the narcotic, the researchers found.
The study is thought to be the first to look at the effects of cannabis effectivenes on brain structure, and been shown that greater use of skunk may cause more damage to the corpus callosum, attaining communications across the brains hemispheres less efficient.
Paola Dazzan, a neurobiologist at the Institute of Psychiatry at Kings College London, said the effects appeared to be linked to the level of active ingredient, tetrahydrocannabinol( THC ), in cannabis. While traditional different forms of cannabis contain 2 to 4% THC, the more potent assortments( of which there are about 100 ), can contain 10 to 14% THC, according to the DrugScope charity.
If you look at the corpus callosum, what were seeing is a significant difference in the white matter between those who use high effectivenes cannabis and those who never use the narcotic, or use the low-potency narcotic, said Dazzan. The corpus callosum is rich in cannabinoid receptors, on which the THC chemical acts.
