What is vaping?

Vaping is the act of inhaling the aerosol from an e-cigarette. E-cigarettes are electronic devices that deliver nicotine and other chemicals directly to the lungs. They can be refillable or disposable.

They are also known as:

  • electronic nicotine delivery systems (ENDS)
  • e-devices
  • e-pens
  • e-hookahs
  • vape pipes
  • vape pens
  • dab pens
  • dab rigs
  • juice
  • JUULs
  • mods
  • pod-mods
  • cigalikes

What is in the vaping aerosol?

The aerosol that is inhaled from the e-cigarette is not water vapor. In fact, the "vapor" contains cancer-causing chemicals, heavy metals, nicotine, volatile organic compounds (VOCs), ultrafine particles, and flavorings known to cause lung damage.

  • hurt heart and lungs

Additional truths about vaping

  1. Nicotine harms: Nicotine lowers the amount of oxygen and nutrients that can get to the growing fetus.
  2. Higher nicotine absorption: E-cigarettes are made to get more nicotine into the bloodstream, with less irritation, than regular cigarettes.
  3. Labeling problems: Some products labeled as 0% nicotine actually had nicotine in them when tested in a lab.
  4. Poisoning: Adults and children can be poisoned by vape juice by swallowing, breathing, or absorbing the liquid through skin and eyes. If you have concerns, call the Poison Help Hotline at 1-800-222-1222.
  5. COVID-19: People who vape have a higher risk of getting COVID-19 than those who do not use e-cigarettes.

If you have concerns or if someone has ingested nicotine, especially a child, call the Poison Help hotline immediately at 1-800-222-1222.
