Use of e-cigarettes or e-cigs is called “vaping,” which uses cartridges that are filled with liquid nicotine, flavoring and other chemicals, and is then heated into a vapor and inhaled. Starting in September 2019, the Centers for Disease Control
and Prevention (CDC) has been reporting on a nationwide outbreak of severe lung disease linked to vaping called vaping-associated pulmonary injury (VAPI).
This is also sometimes referred to as e-cigarette/vaping-associated lung injury (E/VALI).
