Vaping and E-cigarettes

How common is e-cigarette use among teens?

According to the FDA and CDC’s Annual National Youth Tobacco Survey, about 1 in 10 middle and high school students in 2022 vaped in the previous 30 days. 27% of these individuals vaped daily, while more than 40% vaped at least 20 of the last 30 days. 85% used flavored e-cigarettes. About half used disposable e-cigarettes and a quarter used refillable pods or pre-filled cartridges.

What are e-cigarettes?

E-cigarettes are devices that turn liquids into vapor, hence the term vaping.  Another name is Electronic Nicotine Delivery Systems (ENDS). The appeal to adolescents is not surprising.  There are flavors to make it ”taste” better (see statistic above, 85% of users consume flavored products). There is a false perception of safety.  A user can vape other liquids too, such as alcohol and marijuana.  Up until 2016, adolescents could purchase e-cigarettes.  Since then the law states that no one under 18 years old can purchase them.

There is a wide variety of types of e-cigarettes.  Common names for them are vapes, mods, tanks, pod systems (JUUL).  Early products resembled cigarettes but the most current ones are tank-style systems with large refillable cartridges.  Many of the new designs resemble a pen, small flashlight or a computer flash drive.  The term “mods” is used because of the ability to modify the devices.

What do parents need to know about vaping?

  1. E-cigarettes don’t look or smell like cigarettes. Therefore, it may be harder to tell if your child is using them. In fact, the flavor is the most appealing factor at first. Unfortunately, the nicotine from e-cigarettes that accompanies those flavors is addictive like that from cigarettes.
  2. Due to Big Tobacco-esque marketing efforts, vaping has become the new “cool” thing to do. Adolescents see vaping in movies, on TV shows, in commercials, in digital ads on favorite websites and social media, and in print ads in favorite magazines. The CDC, American Academy of Pediatrics and other health organizations remain on the front lines to better educate parents and young people about the potential dangers of vaping. These organizations also play a large role in advocacy and lobbying lawmakers to put safety laws in place to limit access and appeal to young people.
  3. Vaping has been marketed as a safer alternative to cigarettes due to the lack of tar and perceived decreased effect on the lungs. It has also been marketed to help individuals stop smoking cigarettes. However, e-cigarettes have thousands of chemicals like regular cigarettes. The vaporization process creates other chemicals like carbon monoxide that are harmful to the lungs. Additionally, the nicotine in liquid tobacco for vaping is addictive all the same. Adolescents and young adults who use e-cigarettes are 3.6 times more likely to use traditional cigarettes.
  4. One of the complications of e-cigarette use that most concerns healthcare providers is EVALI (E-cigarette or Vaping Product Use Associated Lung Injury). EVALI is caused by vaping either with e-liquids and more prevalently THC and presents with either or both of respiratory and gastrointestinal symptoms.  The symptoms can be mild such as asthma like symptoms or severe requiring hospitalization.
  5. E-cigarettes are the new “gateway drug.” For decades data have shown adolescents are far more likely to try illicit drugs like marijuana, cocaine, heroin and meth if they already smoke cigarettes. Emerging data show e-cigarettes have a similar relationship. Additionally, e-cigarette use in adolescence is strongly associated with later daily cigarette smoking (Pierce et al. Pediatrics January 2021).
  6. Talk to your adolescent if (s)he is becoming more reclusive, more secretive, or less hungry than usual (nicotine side effect). Ask him/her what they have heard about vaping or if they know of people/friends at school who vape. Do not broach the subject in an accusatory manner. Seek to have an open dialogue about it.

What do teenagers need to know about vaping?

  1. Liquid nicotine is just as addictive as the nicotine in cigarettes. Nicotine is consistently ranked as one of the most addictive, if not the most addictive, substances on earth. Trying it once can get you hooked.
  2. Vaping is bad for your lungs. You may not get tar deposits like you would with cigarettes, but liquid nicotine used in e-cigarettes can harm lungs too. Carbon monoxide is inhaled while vaping, as well as many of the thousands of chemicals (>4,000 in fact) in tobacco products besides nicotine.  Many of these substances are considered toxic and cancer-causing.  These substances also cause decreased endurance, speed and power in competitive athletes.
  3. Nicotine changes your brain too. The wiring and chemical connections in your brain are still developing into your 20’s. Nicotine prevents the wiring and chemical connections from forming normally. This increases your risk for:
  • Addiction (to nicotine as well as other substances such as alcohol, drugs and medications)
  • Anxiety and/or Depression
  • School struggles (decreased ability to get and stay focused in class and while studying)
  • Poor decision making (decreased impulse control) is a great resource to help teens quit e-cigarettes
