To vape or not to vape: Is that really a question?

Barbara Howard, MD

All pediatricians are relieved that the rates of children smoking cigarettes has dropped steadily since 2011. This decline seems to be associated with education on the dangers of cigarettes and fewer parents smoking. Perhaps less modeling of cigarette use in movies (although it increased again from 2010 to 2019) and lawsuits against advertisements targeting children also has helped.

“Whew,” we may have said, “we can relax our efforts to convince children to avoid smoking.” But, as is commonly true in medicine, the next threat was right around the corner – in this case vaping or e-cigarettes, also called vapes, e-hookahs, vape pens, tank systems, mods, and electronic nicotine delivery systems. And the size of the problem is huge – over 20% of high school students report using e-cigarettes – and immediate, as vaping can kill in the short term as well as causing long-term harm.

“E-cigarette, or vaping, product use–associated Lung Injury” – EVALI for short – has killed 68 vapers and hospitalized thousands. EVALI is thought to be caused by a vitamin E acetate additive used when vaping marijuana, particularly from informal sources like friends, family, or in-person or online dealers.

Vaping increases the risk of severe COVID-19 disease

 

While EVALI deaths dropped in months after being explained, the COVID-19 epidemic is now a much greater threat to vapers. Vaping, smoking, and even second-hand smoke are associated with a greater likelihood of infection with COVID-19. Vaping increases risk of severe COVID-19 disease because of its immediate paralysis of lung cilia. Sharing vape devices and touching one’s lips while using also increase the risk of virus transmission. Vaping and smoking increase the number of ACE2 receptors to which the SARS-CoV-2 virus attaches causing the characteristic cell damage, and suppresses macrophages and neutrophils, resulting in more smokers testing positive, being twice as likely to develop a severe illness and get hospitalized because of pneumonia from COVID-19, and being less likely to recover. Unfortunately, addressing this new threat to the immediate and long-term health of our patients appears to be more complicated than for addressing smoking tobacco. First of all, vaping is much more difficult to detect than smelly cigarettes sending smoke signals from behind the garage or in the school bathrooms. Many, if not most, adults do not recognize the vaping devices when they see them, as many are tiny and some look like computer thumb drives. The aerosol emitted when in use, while containing dangerous toxins, has less odor than tobacco smoke. Vaping equipment and ads have been designed to attract youth, including linking them to sports and music events. Vaping has been advertised as a way to wean off nicotine addiction, a claim that has some scientific evidence in adults, but at a lower dose of nicotine. Warning children about the dangers of marijuana vaping has been made less credible by the rapid expansion of legalization of marijuana around the United States, eliciting “I told you it was fine” reactions from youth. And the person vaping does not know what or how much of the psychoactive components are being delivered into their bodies. One Juul pod, for example, has the equivalent in nicotine of an entire pack of 20 cigarettes. They are highly addictive, especially to the developing brain, such that youth who vape are more likely to become addicted and to smoke cigarettes in the future.

Help from federal regulation has been weak

 

While all 50 states ban sales to youth, adults can still buy. Food and Drug Administration limitations on kid-friendly ads, and use of sweet, fruity, and mint flavorings that are most preferred by children, apply only to new producers. The FDA does not yet regulate content of vaping solutions.

So we pediatricians are on the front line for this new threat to prevent vaping or convince youth to cut down or quit. The first step in addressing vaping is being knowledgeable about its many known and emerging health risks. It may seem obvious that the dangers of vaping microscopic particles depends on the contents. Water vapor alone is not dangerous; in fact, we prescribe it in nebulizers. Unfortunately, the contents of different vaping products vary and are not well defined in different vape products. The process of using an electric current to vaporize a substance can make it more toxic than the precursor, and teens have little idea about the substances they are inhaling. The psychoactive components vary from nicotine to tetrahydrocannabinol in varying amounts. These have the well known effects of stimulation or a high, but also the potential adverse effects of poor concentration, agitation, and even psychosis. Most e-cigarettes contain nicotine, which is highly addictive and can harm adolescent brain development, which continues into the early- to mid-20s. About two-thirds of Juul users aged 15-24 years did not know that it always contains nicotine, as do 99% of all vape solutions (Centers for Disease Control and Prevention, 2020). Earlier use of nicotine is more highly associated with later addiction to tobacco products that cause lung damage, acid reflux, insulin resistance, harm to the testes, harm to fetuses, cancer, and heart disease.

E-cigarette aerosols also contain dozens of other harmful substances besides nicotine ranging from acetone, propylene glycol, and metals to formaldehyde and ethyl benzene. These same chemicals are part of familiar toxic substances such as antifreeze, paint thinner, and pesticides. These cause ear, eye and throat irritation, and impairments in the cardiovascular system reducing athletic ability – at the least. Some flavorings in vape fluids also are toxic. Even the residual left on furniture and floors is harmful to those coming in contact, including pets.

How to encourage teens not to vaping

 

Trying to scare youth about health hazards is not generally effective in stopping risk behaviors since adolescence is a time of perceived singularity (it does not apply to me) and even a sense of immortality. Teens also see peers who vape as being unaffected and decide on using based on this small personal sample instead of valid statistics.

But teens do pay some attention to peer models or influencers saying why they do not use. One source of such testimony you can refer to is videos of inspiring athletes, musicians, and other “cool” young adults found on the naturalhigh.org website. You may know other examples of community teens desisting you can reference.

Parent rules, and less so advice, against smoking have been shown to be effective in deterring youth cigarette smoking. Because parents are less aware of vaping and its dangers, another step we can take is educating parents in our practices about vaping, its variable forms, its effects, and dangers, supplying authoritative materials, and advising them to talk with their children. Other steps the American Academy of Pediatrics recommends regarding smoking is for parents to be a role model of not using or try to quit, designate the house and car as smoking free, avoid children viewing smoking in media, tell their children about the side effects, and encourage their children who use to quit. Parents also can encourage schools to teach and have rules about smoking and vaping (e.g., med.stanford.edu/tobaccopreventiontoolkit.html).

Another approach we have been using is to not only screen for all substance use, but also to gather information about the teen’s strengths, activities, and life goals both to enhance rapport and to reference during motivational interviewing as reasons to avoid, reduce, or quit vaping. Motivational interviewing has been shown to help patients make healthier lifestyle choices by nonjudgmentally exploring their pros and cons in a conversation that takes into account readiness to change. This fits well with the stage of developing autonomy when teens want above all to make their own decisions. The cons of using can be discussed as including the effects and side effects of vaping interfering with their favored activities and moving towards their identified goals. Praising abstinence and asking them to show you how they could decline offers to vape are valuable reinforcement you can provide.

Finally, we all know that teens hate being manipulated. Vaping education we provide can make it clear that youth are being tricked by companies – most being large cigarette producers who know the dangers of vaping – into getting addicted so these companies can get rich on their money.
