Recent findings presented at the American Heart Association’s Scientific Sessions suggest that regular cannabis consumers might face elevated risks of cardiovascular disease and stroke. Researchers at Tulane University analyzed nationally representative survey data to examine the health habits and trends of nearly half a million adult respondents collected between 2020 and 2024 through the Centers for Disease Control and Prevention.
The study found that individuals who reported regular cannabis use were roughly 20 percent more likely to report a history of cardiovascular issues compared to non-users. Interestingly, the data revealed a non-linear relationship regarding frequency. The elevated risk did not scale predictably with heavy consumption, as occasional users actually showed a higher reported risk of stroke compared to heavy daily users.
While these findings remain preliminary and have not yet undergone full peer review, they add to a growing body of literature examining the physiological impacts of cannabis as recreational legalization spreads. Scientists emphasize that the current data demonstrates correlation rather than definitive causation. Nonetheless, researchers suggest that patients and healthcare providers should factor cannabis consumption into routine cardiovascular health discussions alongside traditional substances like tobacco and alcohol.
