Participants will be recruited from sites in Denver and across the United States
Various types of biologic samples will be obtained from ambulatory participants (with AUDs or chronic cannabis use, and matched controls) and patients (with respiratory failure (COVID-19 positive and negative), or with burn injury) enrolled in consortium investigations that may include bronchoalveolar lavage (fluid and cells), bronchial brushings, nasal brushings, tracheal aspirate, plasma, serum, cryopreserved peripheral mononuclear cells, urine and stool.
Human participants data collected as a part of CoPARC investigations will be stored on the REDCap system. The data can be accessed by designated investigators as part of on-going research efforts.
