We report a case of a man in his 40s presented to the emergency department twice, 1month apart, with severe ischaemic sounding chest pain within 1h of smoking marijuana on both occasions. He had elevated serial biomarkers and ischaemic electrocardiogram changes. His coronary angiograms on both episodes were entirely normal along with normal echocardiogram. This potentially suggests a coronary vasospasm as an underlying mechanism for these non-ST elevation myocardial infarctions. This should alert clinicians and the public alike to this potential risk of cannabis use.
