Large US Survey Links Cannabis Use to Higher Reported Heart Disease Odds

A huge new US study is putting cannabis and heart health under the microscope. Researchers pooled 2020 to 2024 telephone survey data from 442,906 adults with an average age of 49. People who used cannabis one to five days a month had 23 percent higher odds of reported cardiovascular disease than non-users.

Heavy users, who consumed cannabis sixteen to thirty days a month, showed 21 percent higher odds. The link was strongest for stroke, while no statistically significant connection appeared with heart attack. The analysis adjusted for tobacco, alcohol, obesity, diabetes, kidney disease, inactivity, education and income, which makes the signal harder to dismiss.

Still, this is not proof that cannabis causes heart disease. The data is a single snapshot, relies on self-reporting, lacks information on potency or amount, and the non-user group may include former users. Treat it as a warning flag, and talk with your doctor if you use cannabis and worry about your heart.
