What are e-cigarettes?

Dangers of e-cigarettes

The lung injury known as EVALI (e-cigarette, or vaping, produce-use associated lung injury) was recognized in the summer of 2019, with cases peaking in September 2019 and steadily declining since then. It can present as progressive lung illness that can result in severe lung injury, hospitalization, and death.  Most, but not all, cases have been associated with people using informally sourced THC vape products, such as those bought on the street. Vitamin E acetate, a product used in many foods and cosmetics, has been linked with EVALI and has been found in many street-obtained THC products. Vitamin E acetate is typically safe for ingestion and application on the skin, but research suggests that when it is inhaled it can disrupt normal lung function. While vitamin E acetate seems to be a causative chemical, there is not enough evidence to say it is the only chemical in e-cigarettes that causes EVALI. Most of the flavorings and other ingredients in e-cigarette liquid have not been studied when inhaled and many of the risks with vaping are still unknown.
