Key Findings:  This review aims to better explain the mechanism of Δ9-tetrahydrocannabinol (THC) as it binds to cannabinoid receptor 1 (CB1/CNR1) and its role in inflammation, oxidative stress, and coronary vascular disease. Results confirmed cannabis use led to an increase in myocardial infarction (MI) compared to non-users. However, CB1 antagonists may provide a therapeutic target in preventing and/or treating vascular inflammation and heart disease.
