More than four decades ago, the United States Surgeon General issued a warning regarding the medical problems of marijuana smoking, including cardiac toxicity. Since then, many reports have described atrial fibrillation, ventricular tachycardia, acute coronary syndromes, and cardiac arrest temporally related to marijuana use. The subjects were quite young, with no significant cardiovascular risk factors, with the only obvious trigger being marijuana use. Despite these strong signals, the drug is now legalized for recreational use in many states. We believe the time has come to conduct definitive studies about the safety of marijuana before this trend moves to the rest of the nation.
