Substance use is common among lung transplant donors, but concerns persist about graft damage. Stimulant drugs such as cocaine and methamphetamine can induce pulmonary arterial hypertension, while smoked products such as cannabis and crack cocaine can produce airway and parenchymal diseases. We sought to characterize donor substance use at our center and evaluate the associations with recipient survival as well as chronic lung allograft dysfunction (CLAD), severe primary graft dysfunction (PGD3), and baseline lung allograft dysfunction (BLAD).
