According to a new study, smoking high-potency skunk-like cannabis can significantly damage white matter, which is responsible for connecting different areas of the brain.
The team explored the impact of cannabis potency in inducing psychosis. They used an MRI technique to look at the white matter of 99 people, 56 of which had reported a first psychotic episode. They found that white matter damage was significantly greater among heavy users of high-potency cannabis compared to occasional or low-potency users.
Dr. Paola Dazzan, reader in neurobiology of psychosis from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King’s College London, and senior researcher on the study, said in a statement: “We found that frequent use of high potency cannabis significantly affects the structure of white matter fibres in the brain, whether you have psychosis or not. This reflects a sliding scale where the more cannabis you smoke and the higher the potency, the worse the damage will be.”
