BACKGROUND Cannabis use has increased among young individuals in recent *** dependent cannabis use disorder(CUD)has been associated with various cardiac events,its effects on young adults without concurrent substance use remain *** To examine trends in hospitalizations for major adverse cardiac and cerebrovascular events(MACCE)in this *** used the National Inpatient Sample(2016-2019)to identify hospitalized young individuals(18-44 years),excluding those with concurrent substance usage(tobacco,alcohol,and cocaine).They were divided into CUD+and CUD-.Using International Classification of Diseases-10 codes,we examined the trends in MACCE hospitalizations,including all-cause mortality(ACM),acute myocardial infarction(AMI),cardiac arrest(CA),and acuteischemic stroke(AIS).RESULTSOf 27.4 million hospitalizations among young adults without concurrent substance abuse,4.2%(1.1 million)hadco-existent *** CUD+group,hospitalization rates for MACCE(1.71%vs 1.35%),AMI(0.86%vs 0.54%),CA(0.27%vs 0.24%),and AIS(0.49%vs 0.35%)were higher than in CUD-group(P<0.001).However,rate of ACMhospitalizations was lower in CUD+group(0.30%vs 0.44%).From 2016 to 2019,CUD+group experienced arelative rise of 5%in MACCE and 20%in AMI hospitalizations,compared to 22%and 36%increases in CUDgroup(P<0.05).The CUD+group had a 13%relative decrease in ACM hospitalizations,compared to a 10%relative rise in CUD-group(P<0.05).However,when adjusted for confounders,MACCE odds among CUD+cohort remain comparable between 2016 and *** CUD+group had higher rates of MACCE,but the rising trends were more apparent in the CUD-group ***,the CUD+group had lower ACM rates than the CUD-group.
