This is an observational - data and specimen collection study. There have been increasing reports of vaping-induced lung injury, including severe lung injury and rare cases of death. The mechanism by which vaping contributes to lung injury in susceptible persons is unknown, as is impact on chronic lung disease. The investigators aim to identify individuals with chronic electronic nicotine delivery device (ENDD) exposure and matched controls within our ongoing cohort of HIV+ and HIV-uninfected individuals, collect PFT data, bank respiratory and stool samples and collect clinical data for studies of clinical risk, inflammation, biomarkers, and the microbiome in the identification and modification of risk of progression to lung injury or chronic pulmonary disease.
