| Description | Adolescents who regularly smoke marijuana risk damaging a key brain pathway associated with language development and some predisposed to schizophrenia may contract the illness early, researchers said on Wednesday.
Brain scans revealed microscopic abnormalities in a region of the brain that governs higher aspects of language and listening functions in adolescents who are heavy marijuana smokers.
Similar damage to the bundle of fibers, called the arcuate fasciculus, that connect the Broca's area in the left frontal lobe and the Wernicke's area in the left temporal lobe was found in the brains of marijuana smokers and schizophrenics studied. |
