JUUL. Vapes. Vape Pens. E-cigarettes. What's the Difference?

What Parents Should Know about E-Cigarettes and Kids.

White, black and gray JUUL e-cigarettes

Are e-cigarettes less harmful than cigarettes?

There is no FDA oversight of the manufacturing of these products—which means there is no oversight regarding potentially harmful ingredients.

  • E-cigarettes almost always contain harmful ingredients including nicotine.
  • Acrolein, a known ingredient of many e-cigarettes, causes irreversible lung damage.
  • Nicotine exposure during adolescence can harm the developing brain.
  • The most popular e-cigarette among teens is JUUL
    • All JUUL pods contain some nicotine—something many youths don't realize.
    • According to the manufacturer, one JUUL pod may contain as much nicotine as a pack of cigarettes.
  • No e-cigarette has been found to be safe and effective by FDA in helping smokers quit.

Is there a difference between e-cigarettes and JUULing?

  • No. JUULs may look different, but they're actually a type of e-cigarette.
  • E-cigarettes are battery powered and deliver nicotine through a liquid which turns into an aerosol.
  • The e-liquids come in fruit flavors that appeal to youth.
  • JUUL is more discrete and looks like a USB drive. Other e-cigarettes may look like phones.
  • Cartridge-based e-cigarettes like JUUL contain nicotine salts that do not produce vapor or visible emissions when the device is used and may make the product even more addictive.
  • JUUL claims that some of its pods have roughly as much nicotine as an entire pack of cigarettes.

How bad is the e-cigarette epidemic?

Most common reasons youth use e-cigarettes1

  • 39% Use by "friend or family member"
  • 31% Availability of "flavors such as mint, candy, fruit, or chocolate"
  • 17% Belief that "they are less harmful than other forms of tobacco such as cigarettes"

Does the American Lung Association agree with the Food and Drug Administration that youth use of e-cigarettes has reached an epidemic?

  • Yes, the American Lung Association agrees that e-cigarette use among youth has reached epidemic levels.
  • American Lung Association has been asking the FDA to take action on e-cigarettes for a decade.
  • E-cigarettes are the most commonly used tobacco products among youth and have been for several years now.
  • Many youth don't realize how they are harming their lungs and their brains by using e-cigarettes.

Several years ago, one study estimated there were about 7,700 flavors of e-cigarettes on the market at that time.

How is the American Lung Association helping your children?

  • The American Lung Association urges the Food and Drug Administration to take meaningful action to crack down against products that target youth.
  • The Lung Association and our partners filed a lawsuit against FDA for its delay of reviewing products currently for sale.
  • The American Lung Association is working to implement proven effective policies that will reduce youth from e-cigarettes, including raising the minimum age of sale to 21 and increasing the price of products.
