Here's What Potent Pot Does to Your Brain
Study finds damage in white matter used to send signals
Guardian. The alteration in this region, called the corpus callosum, "reflects a problem in the white matter that ultimately makes it less efficient," says neurobiologist Paola Dazzan.
The brains of people who had never used cannabis or smoked less potent forms looked normal, leading researchers to conclude that high-strength versions, like skunk, may damage nerve fibers.
The UK Times reports the damage is similar to the effects of a concussion. "We don't know exactly what it means for the person, but it suggests there is less efficient transfer of information," Dazzan says, per Yahoo.
So what's doing the damage? Dazzan believes it's the THC in cannabis; less potent varieties contain 2% to 4% THC, while more potent forms contain 10% to 14%. The chemical acts on the cannabinoid receptors found in the corpus callosum, according to a release. Though researchers haven't proven cannabis is responsible for the changes, "it is extremely important to gather information on how often and what type of cannabis is being used," Dazzan says.
