The American Journal of the Medical Sciences noted that taking marijuana before a transplant “was not related with post-transplant infections or readmissions up to one year post-surgery” and that “there was no significant difference in overall mortality between marijuana users and non-users.”
Although this study’s sample size was small and it only included patients from the University of Alabama in Birmingham, similar findings from other studies have been found. In their article for The American Journal of the Medical Sciences, the researchers found that just 32 of the 111 cannabis-using individuals had their livers transplanted. The remaining 79 applications were rejected for a variety of factors, such as insurance or financial concerns; 41 of them were expressly rejected because they had “continuing marijuana usage” as one of several non-compliance issues. Only 11 people were turned away for consuming marijuana.Researchers at the University of Alabama at Birmingham evaluated the survival statistics of liver transplant recipients according to their cannabis use in an effort to determine whether these types of transplant limitations have any medical justification. During liver transplant evaluations between 2016 and 2021, 111 patients who tested positive for cannabis on a urine drug screen were enrolled in the study.
