Cannabis Use Linked to Higher Heart Attack Risk
Two studies published in March 2025 found that cannabis users are more likely to suffer a heart attack, with younger adults facing a six-fold increased risk. The findings, based on a retrospective study of 4.6 million people and a meta-analysis of 12 previous studies, suggest a 50% increased risk among cannabis users. The studies' implications for public health and policy are being debated.
Key points
- The American College of Cardiology published two studies in March 2025 linking cannabis use to a higher risk of heart attack.
- A retrospective study of 4.6 million people found that cannabis users under 50 were over six times more likely to suffer a heart attack.
- A meta-analysis of 12 previous studies showed a 50% increased risk of heart attack among cannabis users.
- Researchers recommend that clinicians ask about cannabis use to assess patients' cardiovascular risk.
- The findings have sparked debate on public health and policy implications, with no clear warnings or regulations in place.
Cannabis Use Linked to Higher Heart Attack Risk
Two studies published in March 2025 by the American College of Cardiology have found a significant link between cannabis use and an increased risk of heart attack. The findings, based on a retrospective study of over 4.6 million people and a meta-analysis of 12 previous studies, have sparked debate on public health and policy implications.
Study Findings
The retrospective study found that cannabis users under 50 were over six times more likely to suffer a heart attack compared to non-users. The meta-analysis, which is the largest pooled study to date examining heart attacks and cannabis use, showed a 50% increased risk among cannabis users.
Implications
The researchers recommend that clinicians ask about cannabis use to assess patients' cardiovascular risk, similar to asking about smoking cigarettes. However, there are currently no clear warnings or regulations in place for cannabis use, particularly in states where it is legal to buy, sell, and use recreationally.
Next Steps
The findings have significant implications for public health and policy. As the use of cannabis continues to rise, it is essential to understand the potential risks and develop strategies to mitigate them. Further research is needed to fully understand the relationship between cannabis use and heart attack risk.
