A recent study has revealed that cannabis use negatively impacts brain function, particularly in young adults at risk of psychosis. Researchers at McGill University found that cannabis use reduces brain connectivity and decreases synaptic density, which is crucial for effective brain communication. The study, published in November, involved 49 participants aged 16 to 30, including individuals with recent psychotic symptoms.
The study suggests that lower synaptic density is linked to social withdrawal and lack of motivation, symptoms difficult to treat. The researchers emphasize that cannabis disrupts the brain’s natural process of synaptic pruning, which is essential for brain development.
