Q: If I vape tobacco or nicotine am I at risk for complications from COVID-19?
A: E-cigarette use can expose the lungs to toxic chemicals, but whether those exposures increase the risk of COVID-19 or the severity of COVID-19 outcomes is not known. However, many e-cigarette users are current or former smokers, and cigarette smoking increases the risk of respiratory infections, including pneumonia.
