    BackgroundWhile an association between cannabis use and the risk of atherosclerotic cardiovascular diseases (ASCVD) has been reported numerous times, it remains inconclusive as to whether this link is causal in nature. We sought to consolidate data from observational studies to explore the association between ever use of cannabis and ASCVD outcomes, including myocardial infarction, stroke, and a combined measure of any adverse cardiovascular events in comparison to non-users or controls.MethodsWe performed a systematic literature search on PubMed, Scopus, ScienceDirect, and Cochrane Library for relevant studies from inception until April 2024. Statistical analyses utilized RevMan 5.4 with a random effects model. The study protocol has been registered with PROSPERO (CRD42024530366).ResultsOur analysis incorporated data from 17 studies involving a total of 1,902,481 individuals aged between 18 and 74 years, with a mean follow-up duration of 8.5 years. Upon pooled analysis, no statistically significant association was found between cannabis use and the risk of myocardial infarction compared to non-users, with an RR of 1.25 (95% CI: 0.91-1.71, p = 0.17). Similarly, while the risk of stroke showed no significant association with cannabis use (RR: 1.38, 95% CI: 0.88 to 2.16, p = 0.16), a statistically significant association was observed between ever use of cannabis and the composite of any adverse cardiovascular events (RR: 1.48, 95% CI: 1.16-1.90, p = 0.002).ConclusionThe evident statistical correlations between cannabis use and adverse cardiovascular outcomes underscore its potential as a risk factor for cardiovascular disease, suggesting plausibility for a causal relationship between cannabis use and ASCVD. With rising trends in medical cannabis use and cannabis use disorder across age demographics, heightened risk awareness and informed decision-making regarding cannabis consumption are critical priorities in healthcare and public health initiatives.Copyright © 2024 Elsevier Inc.
