Vapes (also called e-cigarettes) are battery-powered devices that heat a liquid called e-liquid or "juice" into a vapor that people breathe in.

Vape liquid usually has nicotine, which is very addictive, and chemicals for flavor.

It also has sticky substances like propylene glycol and glycerol. Many vape liquids have harmful chemicals, including metals like arsenic and chemicals such as formaldehyde, which can cause cancer.
