What Is in E-cigarette Aerosol?
E-cigarette aerosol is NOT harmless “water vapor.”
The e-cigarette aerosol that users breathe from the device and exhale can contain harmful and potentially harmful substances, including:
Ultrafine particles that can be inhaled deep into the lungs
Flavoring such as diacetyl, a chemical linked to a serious lung disease
Volatile organic compounds
Heavy metals such as nickel, tin, and lead
It is difficult for consumers to know what e-cigarette products contain. For example, some e-cigarettes marketed as containing zero percent nicotine have been found to contain nicotine.
