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 chemicals. The nicotine in e-cigarettes and regular cigarettes is addictive. E-cigarettes are considered tobacco products.

Vaping exposes users to harmful ingredients, including:

• Nictoine, a highly addictive substance that negatively affects adolescent brain development
• Prolyene glycol, used to make antifreeze and paint solvent
• Carcinogens, chemical known to cause cancer
• Diacetyl, a chemical linked to serious lung disease
• Acrolein, can cause irreversible lung damage
• Diethylene Gylcol, a toxic chemical used in antifreeze, linked to lung disease
• Heavy metals, such as nickel, tin, and lead
