Vaping & Lung Health: Is It Still a Concern in 2025?

Over the past decade, vaping has gone from a niche trend to a mainstream habit. Initially marketed as a safer alternative to smoking, e-cigarettes quickly gained traction, particularly among teens and young adults. But as new research emerges and regulations evolve, it’s become clear that “safer” doesn’t mean “safe,” particularly for those with preexisting conditions like asthma, allergies, and other lung-related health concerns.

So, is vaping still a concern in 2025? At Lyracore Pulmonary Health, our answer is yes, and here’s why we continue to take vaping seriously, especially when it comes to protecting lung health.

Understanding Vaping: Then vs. Now

Vaping refers to inhaling an aerosol (often called “vapor”) created by heating a liquid that typically contains nicotine, flavorings, and other chemicals. While newer generations of vaping devices have improved in design and delivery systems, the basic principle remains the same: aerosolized chemicals are inhaled deep into the lungs.

When vaping first gained popularity, it was often positioned as a safer alternative to combustible cigarettes, but recent studies have challenged early assumptions about the long-term effects of vaping on lung tissue.

What We Know Now: The Impact on Lungs

Although e-cigarettes do not produce the same tar and many of the known carcinogens found in traditional tobacco smoke, vaping is far from harmless. Here are four important considerations to look at when trying to understand the effects of vaping on the respiratory system:

1. Airway Inflammation
Multiple studies have demonstrated that vaping can lead to increased inflammation in the lungs. Inhaled aerosols can irritate the airway lining, leading to chronic coughing, wheezing, or shortness of breath, even in people with no prior lung disease.

2. Impaired Immune Response
Research from the American Thoracic Society and other peer-reviewed journals has demonstrated that e-cigarette vapor suppresses key immune defenses in the lungs, which can make users more vulnerable to respiratory infections, including pneumonia and bronchitis.

3. EVALI Risk
E-cigarette or Vaping Use-Associated Lung Injury (EVALI) made headlines in 2019, when thousands were hospitalized and several deaths occurred due to severe lung damage from e-cigarettes and vaping. While most EVALI cases were linked to THC-containing products adulterated with vitamin E acetate, the episode underscored how little regulation existed in the vape market and how quickly things can go wrong.

Though EVALI cases have declined due to better awareness and regulation, the condition remains a concern when devices or cartridges are purchased from unverified sources.

4. Long-Term Damage Still Unknown
Perhaps the most significant concern is that the long-term effects of vaping are still not fully understood. Unlike tobacco, which has been studied for decades, e-cigarettes are relatively new. We are only beginning to see the impact of consistent exposure over 5, 10, or 15 years.

New Technology, New Risks

Vape technology continues to evolve, often with higher nicotine concentrations and faster delivery systems. While early “cigalikes” contained low levels of nicotine, today’s disposable vapes and refillable pod systems can deliver as much or more nicotine than a pack of cigarettes, sometimes in just one device, which increases the risk of:

• Nicotine dependence
• Teen addiction
• Inhalation of volatile organic compounds (VOCs) and heavy metals

Some devices also heat liquid at higher temperatures, creating byproducts such as formaldehyde and acrolein, which are chemicals known to damage lung tissue.

Youth and Vaping: Still a Major Concern

Despite increased regulation and education campaigns, vaping remains popular among teenagers and young adults. According to the 2024 National Youth Tobacco Survey, more than 1 in 5 high school students reported using e-cigarettes in the past 30 days.

This matters for lung health because:

• Young lungs are still developing
• Early nicotine exposure alters brain development and increases the risk of addiction
• Teens may be more likely to progress to tobacco or marijuana use

For parents and guardians, this is a critical time to have open conversations about vaping and to help teens understand the risks, not from a moral standpoint, but from a medical one.

What About “Nicotine-Free” Vapes?

Many vape liquids are labeled “nicotine-free,” but testing has shown that some still contain trace levels of nicotine. In addition, the flavoring agents and chemicals used to create vapor can still harm the lungs, even in the absence of nicotine.

Diacetyl (a flavoring chemical linked to bronchiolitis obliterans, or “popcorn lung”) has been found in some flavored vape liquids, despite efforts to remove it. Even ingredients labeled as “generally recognized as safe” (GRAS) for ingestion may be harmful when inhaled.

When to See a Pulmonary Specialist

If you vape and are experiencing any of the following symptoms, we recommend scheduling an evaluation with a pulmonary specialist:

• Persistent cough
• Shortness of breath
• Chest pain or tightness
• Decreased exercise tolerance
• Recurring bronchitis or respiratory infections

Even if you are asymptomatic, discussing your vaping history during routine pulmonary visits is essential for monitoring lung health over time.
