E-Cigarette, Vaping, Terminology and Facts

From US Centers for Disease Control and Prevention

What are e-cigarettes?

  • E-cigarettes are electronic devices that heat a liquid and produce an aerosol, or mix of small particles in the air.
  • E-cigarettes come in many shapes and sizes. Most have a battery, a heating element, and a place to hold a liquid.
  • Some e-cigarettes look like regular cigarettes, cigars, or pipes. Some look like USB flash drives, pens, and other everyday items. Larger devices such as tank systems, or “mods,” do not look like other tobacco products.
  • E-cigarettes are known by many different names. They are sometimes called “e-cigs,” “e-hookahs,” “mods,” “vape pens,” “vapes,” “tank systems,” and “electronic nicotine delivery systems (ENDS).”
  • Using an e-cigarette is sometimes called “vaping” or “JUULing.”

How do e-cigarettes work?

  • E-cigarettes produce an aerosol by heating a liquid that usually contains nicotine, flavorings, and other chemicals that help to make the aerosol.
  • The liquid used in e-cigarettes often contains nicotine and flavorings. This liquid is sometimes called “e-juice,” “e-liquid,” “vape juice,” or “vape liquid.”
  • Users inhale e-cigarette aerosol into their lungs. Bystanders can also breathe in this aerosol when the user exhales it into the air.
  • E-cigarette devices can be used to deliver marijuana and other drugs.

What do e-cigarettes look like?

  • E-cigarettes come in many shapes and sizes. Some look like regular cigarettes, cigars, or pipes. Larger e-cigarettes such as tank systems – or “mods” – do not look like other tobacco products.
  • Some e-cigarettes look like other items commonly used by youth, such as pens and other everyday items. New e-cigarettes shaped like USB flash drives are popular among youth, including JUUL and the PAX Era, which looks like JUUL and delivers marijuana.

What is JUUL?

  • JUUL (pronounced “jewel”) is a brand of e-cigarette that is shaped like a USB flash drive (third from left in illustration). Like other e-cigarettes, JUUL is a battery-powered device that heats a nicotine-containing liquid to produce an aerosol that is inhaled.
  • All JUUL e-cigarettes have a high level of nicotine. According to the manufacturer, a single JUUL pod contains as much nicotine as a pack of 20 regular cigarettes.
  • JUUL is one of a few e-cigarettes that use nicotine salts, which allow particularly high levels of nicotine to be inhaled more easily and with less irritation than the free-base nicotine that has traditionally been used in tobacco products, including e-cigarettes.
  • News outlets and social media sites report widespread use of JUUL by students in schools, including classrooms and bathrooms.
  • Approximately two-thirds of JUUL users aged 15 – 24 do not know that JUUL always contains nicotine.
  • Although JUUL is currently the top-selling e-cigarette brand in the United States, other companies sell e-cigarettes that look like USB flash drives. Examples include the MarkTen Elite, a nicotine delivery device, and the PAX Era, a marijuana delivery device that looks like JUUL.
  • Additional information about USB-shaped e-cigarettes and actions that parents, educators, and health care providers can take to protect kids is available at cdc.gov – search for e-cigarette.

What is in e-cigarette aerosol?

  • E-cigarette aerosol is NOT harmless “water vapor.”
  • The e-cigarette aerosol that users breathe from the device and exhale can contain harmful and potentially harmful substances, including:
  • Nicotine
  • Ultrafine particles that can be inhaled deep into the lungs
  • Flavorings such as diacetyl, a chemical linked to a serious lung disease
  • Volatile organic compounds
  • Cancer-causing chemicals
  • Heavy metals such as nickel, tin, and lead
  • The aerosol that users inhale and exhale from e-cigarettes can expose both themselves and bystanders to harmful substances.
  • It is difficult for consumers to know what e-cigarette products contain. For example, some e-cigarettes marketed as containing zero percent nicotine have been found to contain nicotine.
