Abstract only
Introduction:
Cannabis is a commonly utilized recreational substance which contains numerous bioactive agents. As more states legalize the use of marijuana, it’s effect on various disease conditions is expected to become more pronounced. Cannabis’ anti-inflammatory effects could suppress pro-inflammatory conditions. For example, chronic inflammation with extracellular matrix degradation resulting in weakness and abnormal dilatation of the aortic wall is a hallmark of Aortic Aneurysm. We, therefore, hypothesized that cannabis users would have less prevalence of aortic aneurysms.
Objective:
To identify the relationship between chronic cannabis use (CU) and diagnosis of aortic aneurysms (AA) among hospitalized patients.
Methods:
After selecting patients who were 55 years and above from 2012 to 2014 National Inpatient Sample database, we identified those who had a diagnosis of Aortic Aneurysm and those who utilize Cannabis. We then stratified the CU into two groups: nondependent (NDU) and dependent users (DU). Using logistic regression, we estimated the Odds Ratio (AOR) after controlling for numerous factors.
Results:
In our total 10,461,694 sample, 99.6% (10,419,972) are non-users, 0.37% (38,514) are nondependent users and 0.03% (3,208) are dependent users. About 3.21% (336,202) of the patients had a diagnosis of AA versus 96.79% (10,125,492) without a diagnosis of AA. Compared to non-users of cannabis, the odds of AA is about 35% less among CU (AOR 0.66[0.62-0.71]), 40% less among DU (aOR 0.58[0.44-0.76]), and 33% less among NDU (AOR 0.67[0.62-0.72]). The odds of AA was lower in females (AOR 0.61[0.60-0.610]), but higher in many conditions such as: among >=65 years (AOR 1.16[1.15-1.17]), tobacco users (AOR 1.18[1.17-1.19]), predisposing hereditary conditions (AOR 5.31[4.60-6.13]), and atherosclerosis (AOR 3.04[3.00-3.08]).
Conclusions:
Our result shows that Cannabis use is associated with less occurrence of AA. Cannabidiol, an anti-inflammatory alkaloid in Cannabis could potentially suppress the release of proteolytic inflammatory mediators which might be responsible for the gradual weakening of the vascular walls. We recommend more basic research to evaluate this effect of Cannabidiol.
