A recent study in 2025 suggests that individuals diagnosed with cannabis use disorder—characterized by an inability to stop using cannabis despite its negative effects—face a nearly threefold increase in mortality rates compared to those without the condition over a five-year period. The research indicates that people with this disorder are ten times more likely to die by suicide than the general population. Additionally, they have a higher risk of death from trauma, drug poisoning, and lung cancer. In a separate study researchers found an increase in schizophrenia and psychosis cases in Canada linked to cannabis use disorder following the drug’s legalization.
