As of August 22 2019, there were 193 reported cases of potential severe lung disease associated with e-cigarette use or vaping reported in 22 states1, and one case of death of an Illinois resident2. The state department of health is currently investigating whether or not e-cigarette use is directly associated with severe lung disease. Though all the patients in the reported cases were involved with e-cigarettes, officials have yet to determine a single ingredient or device that is causing issues.
The CDC advises for the general public to not purchase e-cigarette products off the streets nor to modify or add any substances not intended by the manufacturer. Additionally, they recommend that these products should not be used by the youth, young adults, adults who do not currently smoke, and pregnant women. With the increase in American adolescents using e-cigarettes or vaping3, there is a growing concern on the unknown health risks associated with e-cigarettes especially due to the lack of conclusive research done on these products.
