Vaping is not harmless, but the evidence attached to this story does not show pulmonary wards filling across major cities or public-health systems buckling under a new epidemic. Those scenes, economic totals and predictions were added without supporting data.
The underlying commentary assembled research on nicotine, cardiovascular measurements, respiratory symptoms and youth use. That is enough to justify prevention, surveillance and honest cessation advice. It is not enough to turn associations and laboratory findings into a current hospital crisis.
A useful assessment must hold two facts at once. People who have never smoked, especially adolescents and pregnant people, should not be encouraged to vape. Adults who already smoke face a different comparison because replacing combustible cigarettes completely can reduce exposure to many toxic chemicals and may help some people quit.
Known Hazards Do Not Need Invented Hospital Scenes
The US Centers for Disease Control and Prevention says no tobacco product, including e-cigarettes, is safe. Most e-cigarettes contain nicotine, which is highly addictive and poses particular risks during pregnancy and while the adolescent brain is developing.
The aerosol is not simply water vapour. Depending on the product and use conditions, it can contain cancer-causing chemicals, volatile organic compounds, ultrafine particles and metals including nickel, tin and lead. Some flavouring chemicals may be suitable for eating but not for inhalation.
Nicotine can acutely raise heart rate and blood pressure. The commentary cited an observational study in which people who vaped or smoked had nearly 50% higher odds of elevated blood pressure than non-users. Its authors explicitly noted that this did not prove vaping caused the difference, because diet, exercise and other factors could contribute.
Respiratory studies have also reported associations with reduced lung function, wheeze, cough, bronchitis-like symptoms, airway resistance and asthma flares. These signals warrant attention, but they do not establish that every user will develop irreversible scarring or that hospitals are already facing the surge described in the old article.
Long-Term Uncertainty Is Not a Cancer Diagnosis
E-cigarettes are relatively new and products change quickly, so long-term disease estimates remain incomplete. Laboratory studies reporting cell injury or DNA damage can identify biological hazards worth investigating. They cannot determine how many people will develop cancer decades later.
The cited commentary acknowledged that human data have not confirmed that vaping causes cancer. That gap should not be rewritten as proof of either safety or inevitable disease. Exposure, device power, liquid composition, frequency of use, prior smoking and dual use can all affect risk.
The World Health Organization describes e-cigarettes as harmful and not safe. It identifies nicotine addiction, cardiovascular effects, poisoning, burns and respiratory risks while noting that devices and liquids vary. That position supports protective regulation without supplying the hospital counts, insurance effects or organ-failure forecasts previously presented as fact.
Mental-health findings need the same discipline. Surveys have found associations between youth vaping and depression, anxiety or suicidal thoughts. Cross-sectional associations do not show which came first or isolate nicotine from stress, social conditions and other substance use. Nicotine dependence and withdrawal can worsen distress, but a survey link is not a causal diagnosis for an individual.
Smoking Cessation Requires a Different Comparison
Cigarette smoke contains a deadly mixture produced by combustion. CDC notes that e-cigarette aerosol generally contains fewer harmful chemicals, while stressing that fewer does not mean safe. For an adult who smokes, the relevant question is whether vaping replaces cigarettes completely, not whether vaping is harmless in isolation.
A 2025 Cochrane living systematic review included 104 completed studies and 30,366 participants. It found high-certainty evidence that nicotine e-cigarettes increased smoking quit rates compared with nicotine replacement therapy, with an estimated three additional quitters per 100 people. The trials studied regulated nicotine products, and longer, larger studies are still needed to evaluate safety.
That review contradicts a blanket claim that patches and gum have stronger cessation evidence than e-cigarettes. It also does not turn vaping into a risk-free consumer habit. The participants were people trying to stop smoking, not adolescents or never-smokers deciding whether to start using nicotine.
Dual use is another distinction. Continuing to smoke while also vaping preserves exposure to combustible tobacco and is not an effective way to protect health. CDC warns that dual use may produce greater toxic exposure and worse respiratory outcomes than using either product alone.
The Public-Health Case Must Stay Evidence-Bounded
Policy can address youth-oriented flavours and marketing, nicotine concentration, product quality, battery safety, waste and access to cessation support. Health services can record vaping status, advise patients according to age and smoking history, and monitor emerging adverse-event data. None of those steps requires a fabricated dollar total or a claim that wards are already overwhelmed.
Clinicians should also avoid collapsing different products into one category. Regulated nicotine e-cigarettes, illicit liquids and products containing tetrahydrocannabinol can have different risk profiles. The 2019 US lung-injury outbreak, for example, cannot be used as proof that every nicotine device causes the same injury mechanism.
The evidence supports a firm message for young people, pregnant people and never-smokers: do not start. For adults who smoke, the goal remains ending combustible tobacco use, with behavioural support and an informed choice among effective cessation treatments. Complete switching and dual use are not equivalent outcomes.
Vaping deserves scrutiny because addiction and aerosol exposure are real and long-term uncertainty remains. That uncertainty is not permission to manufacture a present-tense collapse. The credible warning is narrower and stronger: prevent new nicotine dependence, help smokers stop combustion, measure harms as they emerge, and refuse to fill evidence gaps with hospital scenes or economic numbers that no cited study reported.
