Weed impacts the cerebellum, the part of the brain responsible for motor functions, and may harm its development.
Our motor functions are regulated by the cerebellum in our brains.
One study on the effects of cannabis on adolescent brain development showed that chronic weed exposure can affect one's cognitive impairment. Cognitive impairment means having trouble with thinking, remembering, or concentrating. It makes it harder to focus, solve problems, learn new things, or remember information. It's like when your brain isn't working as clearly or quickly as it normally does.
Scientists compared the attention maturation of people who use weed with that of participants who had not used weed. People who used weed had “less age-expected improvements on tests assessing sustained attention, visuospatial working memory, and executive functioning” than nonusers. The cerebellum is responsible for these motor functions, and weed may harm its development as shown in this study.
