When a student says they are short of breath after walking upstairs, most educators think asthma, a cold, or maybe anxiety. Over the past few years, another cause has pushed its way into school nurses’ offices and athletic trainer logs: EVALI, the e-cigarette or vaping product use associated lung injury. The term is clinical, but the reality is painfully human. Teens who look fine in first period can be coughing and gasping by lunch. Some end up in intensive care.
Schools sit at the front line. Staff see students every day, hear their coughs, notice their sluggish pace during drills, and catch the subtle behavior changes that parents can miss. Knowing what EVALI looks like, and how it differs from garden variety flu or asthma, helps schools act fast, guide families toward medical care, and reduce the risk of a crisis on campus.

What exactly is EVALI and why did it surge?
EVALI first entered the national conversation in 2019, when hospitals began reporting clusters of severe lung injury tied to vaping. Many cases involved THC vapes adulterated with vitamin E acetate. Once inhaled, that oily additive can wreak havoc on the lung’s delicate architecture. That initial spike has receded, yet cases continue to appear across the country, and adolescents remain a vulnerable group.
Two reasons keep EVALI on the school radar. First, vaping products are prevalent. National surveys show that a significant minority of high school students report current use, though numbers fluctuate year to year. Second, the product landscape shifts constantly. Unknown supply chains, DIY refills, counterfeit cartridges, and super-concentrated nicotine or THC mean the risk profile never stays stable. While not every cough is EVALI, the possibility should stay on the differential diagnosis when a student who vapes shows respiratory symptoms.
How EVALI presents in teens at school
EVALI rarely announces itself with a single dramatic sign. It creeps. A student athlete who used to run the mile without blinking now stops to “catch my breath.” A quiet ninth grader starts missing class after lunch with “stomach issues.” The nurse hears a wet cough that doesn’t clear. By the time pulse oximetry is taken, oxygen saturation might be in the low 90s, but the student still insists they are okay.
The pattern can look like this: several days to weeks of cough, chest pain with deep breathing, shortness of breath, and fatigue. Many adolescents also report systemic symptoms that can mislead the school team at first glance: fever, chills, nausea, vomiting, or abdominal pain. That mixed picture, respiratory plus gastrointestinal, is a hallmark clue. Students with EVALI often have both.
A particular detail to ask about is pleuritic chest pain, the sharp twinge that worsens with inhalation or cough. Another is exertional intolerance. If climbing stairs or participating in warm-ups leaves them winded when that never happened before, the change matters. Not every teen will volunteer that they vape. Some believe their devices are harmless because they only use them “on weekends” or “for stress.” Others are sure their cartridges are safe because a friend bought them from a “trusted” source. The body does not negotiate with intent. Injury can occur anyway.
EVALI vs. common school-day illnesses
The overlap with flu, COVID-19, or asthma complicates decisions in the nurse’s office. Sorting through a crowded hallway of symptoms calls for pattern recognition built on a few questions and simple vitals.
Fever and body aches can mimic influenza, yet EVALI often brings abdominal pain and persistent nausea that do not neatly track with respiratory infections. COVID-19 has broad presentations, but teens with EVALI tend to have more significant hypoxia than their casual appearance suggests. With asthma, wheezing and a history of flares dominate, and rescue inhalers usually help. EVALI can include wheeze, yet bronchodilators alone may not touch the core problem.
One more distinction: timing around vaping. Many adolescents with EVALI report recent escalation in use, a new brand or cartridge, or a shift to THC or unknown oils. Even those who claim they “just tried it a few times” can develop symptoms. The exposure does not require months or years.
What school nurses and staff should watch for during the day
The sensory details matter. Listen to the quality of the cough, look at the effort of breathing, and note color. Pale or slightly gray lips, retractions around the ribs or collarbones, and a student who cannot finish sentences without pausing for air signal danger. If pulse oximetry is available and shows oxygen saturation below about 94 percent on room air in a teen who was previously healthy, that is a red flag in the school setting.
Fatigue that feels out of proportion, dizziness when standing, or a sudden drop in exercise capacity are smaller clues that accumulate into a bigger picture. Any combination of respiratory symptoms with stomach complaints raises suspicion, especially when the student’s social circle mentions vaping or the student smells faintly sweet or chemical when exhaling. If a backpack yields a sleek, USB-like device or a pen-shaped cartridge during a discipline check, connect that find to the symptom assessment, not only to the behavior policy.
The role of candid, nonjudgmental conversation
In my experience, how adults ask about vaping makes the difference between silence and disclosure. Teens are quick studies in shame and will shut down if they sense a lecture. A calm, factual tone works best: “I’m concerned because your cough and shortness of breath could fit a lung irritation we sometimes see with vaping. If you have used any nicotine or THC vapes, it helps me understand how to keep you safe.” Normalize the question by asking all students with similar symptoms, not just those who “look like” they might vape.
Avoid focusing solely on nicotine or only on THC. Many students do not know what is in their cartridges. A gentle request for specifics can help: the brand or street name, where they obtained it, any recent changes, and whether friends have felt sick. Document what is volunteered without interrogating. The goal is care, not a gotcha.
Red flags that call for immediate medical evaluation
Some situations require quick escalation and, in many schools, a call to EMS. The following indicators justify urgent medical evaluation rather than a wait and see approach:
- Oxygen saturation persistently below about 92 to 94 percent on room air, or a rapid drop with minimal activity. Respiratory distress visible as retractions, nasal flaring, inability to speak full sentences, or a respiratory rate above 30. Chest pain that is severe or worsening, especially if accompanied by dizziness or fainting. Cyanosis around lips or nail beds, altered mental status, or signs of dehydration from ongoing vomiting. A student with known vaping exposure plus fever and progressive shortness of breath over days, even if they look “not that sick.”
These criteria err on the side of caution. EVALI can deteriorate quickly, and schools lack the imaging and lab tests that help hospitals confirm the diagnosis. Stabilize, monitor, and transfer.
What EVALI looks like on the medical side, translated for schools
Clinicians diagnose EVALI by excluding other causes. Imaging like a chest X-ray or CT often shows diffuse opacities that reflect inflammation or injury. Oxygen needs can range from none to mechanical ventilation. Treatment varies, but may include supplemental oxygen, steroids to reduce inflammatory damage, and antibiotics if infectious pneumonia has not been ruled out. Recovery can take weeks. Some teens require follow-up for persistent shortness of breath or exercise intolerance.
Why should school staff know this? Because after discharge, that student returns to campus. A 10th grader who spent five days in the hospital for EVALI will not be sprinting the gym pacer test the next week, and they may fatigue after a single flight of stairs. A coordinated plan with the family and medical team prevents a preventable relapse.
The bigger picture: vaping health risks beyond EVALI
While EVALI draws attention because it is acute and dramatic, it is part of a broader set of vaping health risks. Nicotine-heavy products prime the adolescent brain for addiction, and more teens than adults suffer from nicotine poisoning symptoms like nausea, headache, sweating, tremor, and palpitations after high exposure. THC vapes can deliver extremely high concentrations that amplify anxiety or cognitive effects. Flavoring chemicals and other solvents may irritate the airway even without EVALI. Teens also encounter misinformation, like the myth of popcorn lung vaping every time they cough. The reality is that bronchiolitis obliterans, the technical name for popcorn lung, was linked to diacetyl in certain industrial exposures and some flavorings, but most e-liquids today do not list diacetyl and labeling can be unreliable. What schools need to emphasize is simpler and more defensible: inhaling heated aerosols, nicotine salts, and oil-based substances carries real, measurable respiratory effects of vaping, ranging from throat irritation to serious lung injury.
School policies that help without making things worse
Zero tolerance language might feel decisive, but it can backfire when a student fears punishment more than they fear shortness of breath. A better approach separates health care from discipline. If a student presents to the nurse with suspected EVALI symptoms, prioritize assessment and safety regardless of possession rules. For contraband discovered in a backpack search, follow policy, but couple it with an immediate health screening and a referral for support rather than only sanctions.
Communication templates help. A brief, plain-language letter to families, ideally co-signed by the principal and the school nurse, can describe EVALI symptoms, when to seek care, and available resources to quit vaping. Keep the tone informative, not alarmist. Provide a contact for confidential help.
Working the problem in real time: an example from the field
A varsity basketball player walked into the training room between classes complaining of chest tightness. He had no history of asthma. His oxygen saturation was 93 percent at rest, dropping to 89 percent after light jogging in the hallway. His pulse ran high, he felt nauseated, and he had a mild fever. The athletic trainer asked directly about vaping, framing the question as a health screen. The student admitted he had switched to a new THC cartridge from a friend two weeks prior. EMS transported him to the hospital, where imaging supported EVALI. He spent three days on oxygen and steroids. Back at school, the nurse worked with teachers to excuse physical tasks for two weeks and gradually ramp activity as tolerated. The student engaged with a counselor for vaping addiction treatment, found a medical help quit vaping program through a local clinic, and recruited a teammate as an accountability partner. He returned to full play later that season and continues to mentor younger athletes trying to stop vaping.
Practical steps schools can take this semester
Many campuses already have strong systems for asthma or diabetes. EVALI adds a newer layer that benefits from specific protocols. Here is a concise checklist that supports quick action without bogging down staff:
- Build a brief triage pathway: respiratory symptoms plus GI complaints plus possible vaping equals check oxygen saturation and escalate if low. Standardize nonjudgmental screening questions about nicotine and THC use for any student with cough or shortness of breath. Keep an emergency reference card in nurse and coach kits with red flags for immediate EMS activation related to suspected EVALI. Create a parallel pathway for support: confidential referrals to counseling and quit resources rather than only discipline. Plan for re-entry accommodations after hospitalization, including activity modifications and makeup work flexibility.
Five well-executed steps beat a binder full of intentions. Staff turnover and busy days are facts of life. The simpler the pathway, the more likely it is to be used.
Helping students quit vaping without lectures or scare tactics
Telling a teen to quit vaping because it is bad does not move the needle. Motivation strengthens when you connect health, performance, and autonomy. Athletes respond to messages about lung efficiency, recovery times, and stamina. Musicians and singers tune in when you explain how airway irritation degrades tone and breath control. Students with anxiety may use vapes to self-soothe; for them, a replacement strategy matters more than a statistic.
A practical counseling tip: ask for a 2-week experiment rather than a forever pledge. Suggest they remove devices from their room, tell one trusted friend, and replace the ritual with something tactile like gum, a cold water bottle, or paced breathing. Encourage them to keep a note on their phone tracking urges and triggers. Many teens will test themselves if the commitment feels finite. After two weeks, reassess. If they succeed, build on the win. If they slip, normalize it and reset.
Schools can also normalize help-seeking with quiet signals. Flyers in restrooms that list a text-line for teens who want to quit vaping, with no need to talk to an adult first, can catch the kid who is not ready to raise their hand. Partner with local clinics that offer medical help quit vaping, including nicotine replacement therapy suited to adolescents and evidence-based counseling. Not every pediatric practice prescribes nicotine patches or gum for teens, but many do, and some community health centers run group programs tailored to youth. The goal is to present quitting as an attainable, supported choice, not as a moral test.
Dealing with misinformation and student pushback
Expect a few common refrains. “It’s just water vapor.” It is not. The aerosol carries nicotine, ultrafine particles, and solvents that can inflame airway tissue. “My friend vapes every day and is fine.” Bodies vary, and risk is not destiny. The same argument gets used for seatbelts. “I only use nicotine-free juice.” Labels can be inaccurate, and even nicotine-free products can irritate lungs. “Popcorn lung vaping is what I have.” Probably not, and saying so builds credibility. Explain that EVALI is the more relevant concern with acute symptoms, and that diagnosis belongs to a medical team. Staying anchored in what is known defuses the debate.
When nicotine poisoning is part of the picture
Separate from EVALI, schools sometimes see nicotine poisoning after a student vapes intensely or ingests e-liquid accidentally. Symptoms can include nausea, vomiting, stomach pain, sweating, dizziness, headache, salivation, and tachycardia. Severe cases can bring confusion, weakness, or seizures. This overlaps with anxiety and stomach bugs, which is why history matters. If a student reports a binge in the restroom between classes or the scent of sweet solvent is strong on their clothes, consider nicotine exposure. Supportive care in the nurse’s office may suffice for mild cases, but persistent or severe symptoms merit medical evaluation. Poison control centers remain an underused resource for real-time guidance.
Protecting student privacy while engaging families
Privacy laws matter, and so does trust. If a student discloses vaping, clarify what will be shared with parents or guardians and what stays confidential, consistent with state law and school policy. Lead with health: “We’re concerned about breathing difficulties and want to make sure you can get evaluated today.” When calling home, frame the situation as action-oriented rather than accusatory. Families vary in their responses. Some will be grateful, others defensive. Keep the focus on symptoms and safety.
Sustaining the work without burning out staff
EVALI and the wider vaping epidemic can feel like a moving target stacked on top of everything else schools manage. It helps to choose a few durable practices and repeat them until they become muscle memory. Train new teachers and coaches each fall on the red flags. Refresh the nurse’s office protocols every semester. Review the emergency escalation criteria during staff meetings, then keep a laminated copy where it is actually used.
Data helps sustain momentum. Track the number of students assessed for respiratory complaints, referrals to care, and return-to-school plans after hospitalization. You do not need a complicated dashboard. A simple spreadsheet enables the school to advocate for resources: more nurse time, extra pulse oximeters for athletics, or a partnership with a local clinic. When the school board asks what is being done about vaping, you will have specifics rather than generalities.
Final thoughts: lead with care, act with precision
EVALI reminds us that the adolescent body is still under construction. The lungs, the brain’s reward circuits, the sense of invincibility, all of it is in flux. Schools cannot control what every teen inhales after the last bell, but they can do three things exceptionally well: spot patterns early, respond decisively to red flags, and offer pathways to stop vaping that respect a student’s dignity. The quiet saves matter. vaping detection solutions A coach who pauses practice when a player looks winded and sends him to the nurse. A counselor who swaps judgment for curiosity. A nurse who checks oxygen saturation on a kid who claims it is just a cold and catches a number that does not fit.
Those small, practiced moves are how campuses prevent tragedy and, just as importantly, how they help students reclaim their health. EVALI symptoms do not need to escalate on school grounds. With eyes open, language that invites honesty, and a plan that links care to action, schools can protect the lungs that will carry these kids into adulthood.
