New Studies Confirm: Marijuana Use Linked to Higher Risk of Heart Attacks and Stroke

Two new studies presented at the American Heart Association's Scientific Sessions 2023 suggest that regular marijuana use, especially among older individuals, may be associated with a higher risk of heart failure or heart attack. The first study found that daily marijuana users had a 34% increased risk of developing heart failure compared to non-users, although this risk dropped to 27% when accounting for coronary artery disease. The second study revealed that marijuana users aged 65 and older had a 20% increased chance of experiencing a major heart or brain event while hospitalized. Researchers emphasize the need for more data to fully understand the risks of marijuana use and encourage healthcare professionals to inquire specifically about marijuana use when taking patients' medical histories.
