Study: High-Potency Marijuana Linked With Neural Damage

GREAT BRITAIN:  In scanning the brains of drug users, researchers at Kings College London found smokers of high-potency pot had smaller amounts of white brain matter inside their corpus callosum, a neural pathway connecting the left and right halves of the brain.

While pot smokers generally showed more damage to the corpus callosum than non-smokers, those who smoked super strong weed known as ‘skunk’ showed more significant white matter loss.

Scientists performed MRI scans on the brains of 56 patients who had visited a London hospital reporting a first episode of psychosis. The brains of 43 healthy participants were also scanned. All the participants were surveyed about their drug habits.
