Cannabis use disorder among atrial fibrillation admissions, 2008–2018

Abstract

Background: Despite changes inthe legality of cannabis use and the increasing prevalence of cannabis use disorder (CUD), there is little data investigating the association between CUD and inpatient atrial fibrillation (AF) hospitalizations.
