Even occasional marijuana use linked to higher stroke risk, study finds
A study of nearly 450,000 U.S. adults found that any cannabis use, even occasional, is linked to higher odds of stroke and cardiovascular disease.Summary
A new study of nearly 450,000 American adults found that cannabis use is associated with increased odds of cardiovascular disease and stroke, but not heart attacks. The findings, based on CDC survey data from 2020 to 2024 and scheduled for presentation at the American Heart Association's Scientific Sessions 2026, show that both low-frequency and heavy users had elevated risk compared with non-users. People using cannabis one to five days per month had 23% higher odds of reported cardiovascular disease, while those using 16 to 30 days per month had 21% higher odds. Low-frequency users had 40% higher odds of a reported stroke, and heavy users had 25% higher odds. The method of consumption—smoking, vaping or edibles—did not change the risk. Researchers noted the study is observational and cannot prove causation, and it had limitations such as reliance on telephone surveys and lack of data on THC potency. Experts advised that patients should not discontinue prescribed cardiovascular medications based on this report and should discuss cannabis use with their healthcare providers.
