Is vaping harmful for kids and teens?
Yes. A new systematic review screened more than 14,000 published articles and found evidence of harm from vaping across eight separate areas of health in young people aged 0 to 19. The most consistent signals were breathing symptoms, cough, wheeze and bronchitic symptoms, and mental health symptoms, anxiety, depression and panic disorder.
This review comes from the Royal College of Paediatrics and Child Health and was published in Archives of Disease in Childhood. The team searched the medical literature from the beginning of the databases through September 2025. They screened 14,026 articles, read 325 of them in full, and kept the 81 studies that actually measured a health or social outcome in children and young people who vape. That makes it one of the largest attempts so far to answer a question parents keep asking: what is this stuff doing to my kid?
What the review found
Vaping was tied to harm in eight areas: respiratory health, mental health, cigarette smoking initiation, oral and dental health, allergies, sleep, eye symptoms, and outcomes for babies exposed to nicotine before birth.
The clearest findings came from very large surveys. In those, vaping was linked over and over to cough, wheeze, bronchitic symptoms, anxiety, depression and panic disorder. Young people who vape were also more likely to report asthma flare-ups. The individual studies ranged from 83 young people up to 216,056, mostly ages 12 to 19, and a few reached down into early childhood or looked at newborns after nicotine exposure in the womb.
The review reported these as consistent associations rather than as a single pooled number, so there is no one percentage or risk figure to quote here. What carries the weight is the repetition. The same symptoms kept showing up in study after study, in different countries, using different methods.
Does vaping lead to cigarette smoking?
The long-term studies are the ones that matter here, because they follow the same young people forward in time rather than taking one snapshot. Those studies showed strong evidence that young people who vape are significantly more likely to go on to smoke cigarettes.
That undercuts the most common defense of vapes, which is that they are a smoking cessation tool. For an adult who already smokes a pack a day, that argument holds real weight. For a 14 year old who has never touched a cigarette, the traffic appears to run the other direction.
The age detail is worth sitting with. In the smaller set of high-quality studies that broke results down by age, the links to smoking initiation, moving on to cigarettes, and mental health symptoms looked stronger in younger adolescents. The earlier a child starts, the worse the picture appears.
Dr. Kumar’s Take
The nicotine dependence piece is what makes this more than a list of symptoms. A cough resolves. A brain that has learned to need nicotine at 13 carries that forward for decades, and the long-term studies in this review found that young people who vape are significantly more likely to go on to smoke cigarettes.
The mental health finding needs care in how it is read. Anxiety, depression and panic disorder showed up alongside vaping in the large surveys, but most of those studies took a single snapshot in time. A snapshot cannot tell you whether vaping worsened the anxiety or whether anxious teenagers reached for a vape. Both are plausible and both are probably happening. That does not make the association meaningless, it makes it a reason to ask about vaping when a young person presents with anxiety, rather than a reason to say vaping caused it.
The honest gap is time. Vapes have only been widely used for about a decade. This review can describe short and medium-term consequences. Nobody can yet tell you what forty years of vaping does, because nobody has forty years of data.
What this review cannot tell you
Most of the underlying evidence is observational, and much of it is cross-sectional, meaning exposure and symptoms were measured at the same moment. That design shows patterns, not cause. Vaping in young people is also usually self-reported, and teenagers do not always report accurately to adults. The findings on sleep, eye health and allergies were described as emerging, which means there is a signal but not yet enough studies to lean on hard.
None of that erases the core result. When eight different domains of health all point the same direction across 81 studies, the simplest explanation is usually the right one.
Practical Takeaways
- Ask directly and without alarm whether your child has tried a vape, since regular use often starts in early adolescence and the review found the risks look worse the younger it begins.
- If your child has asthma and vapes, treat that as a real trigger worth raising with their doctor, because young people who vape reported more asthma flare-ups.
- Take a new cough, wheeze or chest tightness in a teenager seriously rather than writing it off as a cold that will not clear, as those were among the most consistently reported symptoms.
- Do not accept the smoking cessation argument for a young person who has never smoked, since the long-term studies show vaping in youth points toward cigarettes, not away from them.

FAQs
Is vaping safer than smoking cigarettes for a teenager?
That framing hides the real choice. The comparison only makes sense for someone who already smokes and is trying to stop. Almost no 13 year old is in that position. For a young person who has never smoked, the relevant comparison is vaping versus nothing, and this review found harm across eight domains of health when compared to not vaping. The long-term studies also found that vaping in youth was linked to taking up cigarettes later, so it is not even reliably a substitute.
Do nicotine-free vapes avoid these problems?
This review did not separate its results by nicotine content, so it cannot answer that cleanly. What it can say is that the respiratory symptoms, the cough and wheeze and bronchitic complaints, are not purely a nicotine story. Heated aerosol, flavouring compounds and fine particles all reach the airway regardless of what the label says about nicotine. A nicotine-free vape may sidestep the dependence pathway, but calling it harmless goes well past the evidence.
What about vaping during pregnancy?
The review included perinatal outcomes as one of its eight domains and found adverse outcomes in infants and babies exposed to nicotine during pregnancy. It did not report a single pooled risk figure for this. Nicotine crosses the placenta, and the developing fetal brain and lungs are the two systems least able to absorb an insult. The safest reading of the current evidence is that vaping in pregnancy is not a safe workaround for smoking in pregnancy.
Bottom Line
Eighty-one studies, screened out of more than 14,000 articles, point the same way. Vaping in children and young people is consistently associated with cough, wheeze, bronchitic symptoms, anxiety, depression and panic disorder, along with damage to oral and dental health and a strong link to taking up cigarettes later. The associations look stronger in younger adolescents. The long-term consequences remain unknown, which is an argument for caution rather than comfort. The authors concluded that a stronger legal framework is needed to protect young people from these harms, and the evidence they assembled supports that.
