Commonly known as vaping, e-cigarette use among both youth and young adults has increased considerably in recent years. In 2015, more than a quarter of students in grades 6 through 12 and more than a third of young adults had ever tried vaping. Vaping is the use of devices that heat a liquid into an aerosol that the user inhales. The liquid usually has nicotine and flavoring in it, and other additives. The nicotine in e-cigarettes and regular cigarettes is addictive. E-cigarettes are considered tobacco products because most of them contain nicotine, which comes from tobacco.
Besides nicotine, vaping exposes users to harmful and potentially harmful ingredients, including:
- Ultrafine particles that can be inhaled deep into the lungs
- Flavorants such as diacetyl, a chemical linked to serious lung disease
- Volatile organic compounds
- Heavy metals, such as nickel, tin, and lead
