Heavy cannabis use linked to a significant increase in dementia risk, study finds.
A new study in JAMA Neurology shows that heavy cannabis use can sharply increase the risk of dementia.
The research, which analyzed data from over six million Ontarians aged 45 and older, found that individuals requiring hospital care due to cannabis use had a 72% higher risk of dementia within five years, compared to the general population.
Even those visiting emergency departments due to cannabis use had a 23% increased risk.
While the study suggests that heavy cannabis use might affect brain structure and raise dementia risk, further research is needed to establish a direct cause-and-effect relationship.
