A global review of data indicates that cannabis use may double the risk of death from heart disease and increase the likelihood of stroke by 20%. This research, conducted by experts at the University of Toulouse in France, highlights a significant health concern as cannabis consumption has surged over the past decade. While previous studies have suggested a connection between cannabis use and cardiovascular issues, the extent of this risk has not been clearly defined until now.
To gather concrete evidence, the researchers analyzed large observational studies published between 2016 and 2023 that examined the effects of cannabis on cardiovascular health. Their meta-analysis included 24 studies, aggregating data from approximately 200 million participants predominantly aged 19 to 59. Among the studies that recorded participant gender, it was noted that cannabis users were primarily male and younger than non-users.
The analysis revealed several alarming statistics: cannabis users faced a 29% increased risk of acute coronary syndrome, a 20% greater risk of stroke, and a doubling of the risk of dying from cardiovascular disease. These findings were published in the journal Heart.
Despite these significant results, the researchers acknowledged limitations in their review. Most studies had a moderate to high risk of bias, primarily due to missing data and imprecise cannabis exposure measurements. Many studies were observational in nature, and some utilized overlapping datasets. Nevertheless, the researchers assert that their comprehensive analysis sheds new light on the association between cannabis use and severe cardiovascular conditions.
In a related editorial, Professors Stanton Glantz and Lynn Silver from the University of California at San Francisco emphasized the need for further investigation into the cardiovascular risks associated with various forms of cannabis consumption, including inhaled products and edibles. They noted that cannabis products have become more potent and varied, presenting additional complexities in assessing health risks.
The editorial advocates for integrating cannabis considerations into cardiovascular disease prevention strategies. They argue for the development of effective product warnings and educational initiatives regarding the health risks of cannabis use. As the body of evidence grows, regulatory frameworks should also incorporate health risk minimization alongside market establishment. They propose that cannabis should be treated similarly to tobacco, promoting responsible use while protecting non-users from secondhand exposure.
This study prompts a reevaluation of cannabis’s safety profile, particularly concerning heart health, and underscores the necessity for ongoing research in this evolving field.
