Marijuana Use Tied To Heart Attack, Stroke, And Heart Failure in Older Adults

Heard about the latest studies on marijuana use and heart health? It turns out, even for non-tobacco users, there are some surprising risks. Let’s dive in!

New research presented at the American Heart Association Scientific Sessions in Philadelphia has highlighted the potential cardiovascular risks associated with marijuana use, particularly among older adults. Two non-published studies have revealed concerning findings:

Marijuana Use Among Older Adults: 6 Important Findings

1. Increased Risk of Heart Attack and Stroke: Older adults who use marijuana but do not smoke tobacco face a higher risk of experiencing heart attacks and strokes when hospitalized. This research underlines the dangers of marijuana consumption even in the absence of tobacco use.
2. Elevated Risk of Heart Failure: The second study found that individuals who use marijuana daily have a 34% higher likelihood of developing heart failure, a condition where the heart does not pump oxygenated blood effectively. Age, sex, and smoking history did not appear to impact this risk.
3. Misconceptions About Marijuana and Tobacco: The studies shed light on a common misconception that marijuana smoke is less harmful than tobacco. The research suggests that inhaling marijuana smoke can lead to increased levels of carbon monoxide and tar, akin to smoking tobacco, potentially resulting in heart issues, chest pain, and more.
4. Recommendations to Avoid Smoking and Vaping: The American Heart Association advises people to refrain from smoking or vaping any substance, including cannabis products, due to the potential harm it can cause to the heart, lungs, and blood vessels. This highlights the importance of being aware of the risks associated with these practices.
5. Rising Marijuana Use Among Older Adults: The studies also point out the increasing use of marijuana among older adults. The number of seniors over 65 using marijuana or edibles has doubled between 2015 and 2018, with a 450% rise in past-month binge drinking and marijuana use between 2015 and 2019 in this age group.
6. Cannabis Use Disorder: Nearly three out of every ten marijuana users develop cannabis use disorder, characterized by cravings, irritability, and difficulties in daily life. It becomes an addiction when an individual cannot quit despite its adverse impact.

The unique aspect of one study was the exclusion of tobacco users, enabling researchers to specifically examine the relationship between cannabis use and cardiovascular outcomes.

High blood pressure and cholesterol readings of over 130/80 mm Hg were found to be significant predictors of adverse heart and brain events among marijuana users.

Overall, these studies emphasize the need for individuals, especially older adults, to be aware of the potential cardiovascular risks associated with marijuana use. While some may turn to marijuana for various reasons, understanding these risks and treating them as seriously as other heart disease risk factors is essential.
