According to recent studies presented at the American Heart Association Scientific Sessions in Philadelphia, older adults who use marijuana face a higher risk of heart attack, stroke, and heart failure compared to non-users. These findings, which focused solely on the cardiovascular effects of marijuana use and excluded tobacco smokers, have raised concerns about the potential damaging impact on the heart and blood vessels.

The studies, which are yet to be published, shed light on the growing trend of marijuana use among seniors. The number of individuals aged 65 and over who reported smoking marijuana or consuming edibles has increased significantly in recent years. CNN reports that between 2015 and 2018, this demographic saw a doubling of consumption rates.

One of the studies revealed that frequent marijuana use can have adverse effects on individuals with pre-existing chronic conditions, such as high blood pressure, cholesterol, or diabetes. These individuals were found to have a 20% higher risk of experiencing a heart attack or stroke while hospitalized.

Furthermore, smoking marijuana can lead to short-term lower blood pressure, potentially increasing the risk of stroke if levels drop too significantly. Over time, consistent marijuana use can lead to an increase in blood pressure, creating further cardiovascular difficulties.

The second study, sponsored by the National Institutes of Health, focused on daily marijuana users and found that they were more likely to develop heart failure. Heart failure occurs when the heart is unable to effectively pump oxygenated blood to support other vital organs. According to the U.S. Centers for Disease Control and Prevention, approximately 6.2 million adults in the United States are currently living with heart failure.

Dr. Yakubu Bene-Alhasan, the lead author of one of the studies and a resident physician at Medstar Health in Baltimore, emphasized the importance of providing accurate information about marijuana use to inform policy decisions and educate both patients and healthcare professionals. The findings aim to guide individuals in making informed choices regarding marijuana consumption, particularly given its potential cardiovascular consequences.

The American Heart Association recommends against smoking both tobacco and marijuana due to their known harmful effects on the heart, lungs, and blood vessels. Smoking marijuana leads to increased concentrations of carbon monoxide (a poisonous gas) in the blood, similar to the effects of inhaling tobacco smoke, which can contribute to heart muscle disease, chest pain, heart rhythm disturbances, heart attacks, and other serious conditions.

As marijuana use continues to rise among the elderly population, these studies provide valuable insights into the potential risks associated with its consumption. The findings emphasize the need for further research and education to promote better understanding and awareness of the cardiovascular implications of marijuana use.

Overall, the studies serve as a reminder that while marijuana may have certain therapeutic benefits, caution should be exercised, especially among older adults with pre-existing heart conditions.
