Marijuana is the most commonly used illicit drug while its abuse and dependence has an increasing prevalence among the young population. Marijuana smoking affects the circulatory system triggering various cardiovascular events. Of note, recent case reports indicate a possible association with atrial fibrillation (AF). In this article, we provide a brief systematic review of all reported cases implicating marijuana smoking in AF development and we concisely discuss the potential underlying mechanisms as well as the clinical implications of this emerging association.
