The drug has becoming increasingly commonplace over the past several years — but researchers stress the need for more caution.

An increasing number of studies are showing that marijuana may not be so harmless after all.

In two new studies, to be presented later this month at the American Heart Association (AHA) Scientific Sessions 2023, researchers found that regular marijuana use increased the risk of heart attack, stroke or heart failure — even after factors like type 2 diabetes, high blood pressure and obesity were taken into account.

“Prior research shows links between marijuana use and cardiovascular disease like coronary artery disease, heart failure and atrial fibrillation, which is known to cause heart failure,” lead study author Yakubu Bene-Alhasan, M.D., MPH, a resident physician at Medstar Health in Baltimore, said in a statement. “Marijuana use isn’t without its health concerns, and our study provides more data linking its use to cardiovascular conditions.”

    Important to note that the population of the study all had a history of cardiovascular health issues, and were not representative of the rest of the population.

    Also important to note is the failure to assess a distinction between combustion and non-combustion consumption.

    Combusting marijuana results in particulates, carcinogens [1], lack of oxygen, and off-gasses benzene. [2] These are very important factors to control for, and this distinction was not addressed at all.

    Definitely in need of further studies on the topic. This is an interesting area to explore, but this study falls a little flat in addressing any causation.
