For some time, people have known that using cannabis during adolescence increases the risk of developing cognitive impairment and mental illness (e.g. depression, anxiety or schizophrenia) later in life. Importantly however, the mechanisms responsible for this vulnerability are not well understood. A new study, published in Brain, shows that long-term cannabis use that starts during adolescence damages the neural pathways connecting brain regions, and that this may cause the later development of cognitive and emotional problems.
