Cannabis use and cardiovascular health risks
Overview
Research has identified potential links between cannabis use and increased cardiovascular complications. A study presented at the ANESTHESIOLOGY®2026 annual meeting, involving over 44,000 surgical patients, found that cannabis use is associated with a 46% increased risk of myocardial infarction during or shortly after surgery. While the same research noted a 22% lower risk of venous thromboembolism among users, researchers stated this does not confirm a protective effect and requires more study.
Further analysis published in BMJ Open examined the impact of recreational cannabis legalization in the United States. By reviewing over 50 million hospital discharge records from 2012 to 2018, researchers found that regions with legalization laws saw faster increases in hospital admissions for atrial fibrillation, heart failure, and heart attacks compared to non-legalization regions. In the Western United States, admissions for these conditions rose at rates between 2% and 4% faster following the enactment of such laws. The study noted that patients hospitalized in legalization areas tended to be younger, often from higher-income ZIP codes, and were less likely to identify as white.
