Why This Matters

Vaping involves using electronic devices—such as e-cigarettes or vape pens—that heat a liquid into an aerosol that is inhaled into the lungs. This aerosol is not harmless water vapor and can contain nicotine, flavorings, and other chemicals.

• Some devices look like USB drives, flash drives, or small pens

• Flavors and marketing can make vaping seem harmless

• Many—but not all—products contain nicotine, which can be addictive

Electronic cigarettes do not burn tobacco. Instead, they use a battery-powered heating element to warm a liquid—often called e-liquid or vape juice—into an aerosol that is inhaled.

This liquid may contain nicotine, flavorings, and other chemicals. When inhaled, these substances are delivered to the lungs and can enter the bloodstream.

Vaping devices come in many shapes and sizes, from disposable devices to refillable systems. While designs vary, most devices include a battery, a heating element, and a cartridge or pod that holds the liquid.
