IS a child really breathing safe air while sitting beside a parent who vapes? What may look like harmless ‘water vapour’ that drifts through a living room or a car may carry several substances that are harmful when the child breathes it in.
The growing popularity of electronic cigarettes, commonly known as vapes, has created a new public health concern. While many people assume vaping is safer than traditional smoking, increasing evidence suggests that exposure to vape aerosols may pose significant risks, especially to children.
Children who do not vape themselves can still inhale harmful substances released into the air by nearby users, a phenomenon known as passive vaping or secondhand vaping.
As vaping becomes increasingly common in homes, vehicles and public spaces, concern is growing over invisible exposure of children to vape aerosols.
Thus, parents, caregivers, educators and healthcare professionals must understand its potential effects on both typically developing children and children with special needs.
What is passive vaping?
Passive vaping occurs when a child breathes in aerosols exhaled by someone using an electronic cigarette. Unlike ordinary water vapour, vape aerosols may contain nicotine, ultrafine particles, heavy metals, volatile organic compounds and flavouring chemicals.
These substances can remain suspended in the air and settle on surfaces, creating both secondhand and thirdhand exposure.
Children are particularly vulnerable because their lungs, immune systems and nervous systems are still developing. They breathe faster than adults and therefore inhale a larger amount of airborne pollutants relative to their body size.
Effects on typical children
1. Respiratory problems
One of the most immediate concerns is respiratory health. Regular exposure to vape aerosols may irritate the airways, leading to coughing, wheezing, throat irritation and shortness of breath.
Children exposed to vaping environments may experience worsening symptoms of asthma and increased susceptibility to respiratory infections.
Young lungs are still developing, and repeated exposure to chemical irritants can interfere with normal lung growth and function.
2. Impact on brain development
Nicotine, commonly present in many vaping products, is highly addictive and can affect the developing brain. Although children may not directly vape, passive exposure to nicotine can still occur.
Research suggests that nicotine exposure during childhood can potentially affect attention, memory, learning and emotional regulation.
Since the brain continues developing throughout childhood and adolescence, even low levels of exposure are concerning.
3. Increased risk of ear, nose and throat problems
Children exposed to secondary vape aerosols may experience increased irritation of the eyes, nose and throat.
Parents often report symptoms such as watery eyes, nasal congestion, sore throats and frequent sneezing in environments where vaping occurs regularly.
4. Weakened immune function
Some chemicals found in vape aerosols may affect the body's natural immune defenses. This could make children more vulnerable to infections such as colds, flu and respiratory illnesses.
Frequent illness can disrupt school attendance, learning opportunities and social participation.
5. Behavioural and social influence
Apart from physical health risks, vaping behaviour observed within the family can influence children's perceptions.
When children frequently see family members vaping, they may view it as normal, socially acceptable or harmless.
This increases the likelihood that they may experiment with vaping themselves during adolescence.
Greater risks for special needs children
While passive vaping can affect any child, those with special needs may face greater challenges because many already have underlying medical, developmental or neurological vulnerabilities.
1. Children with Autism Spectrum Disorder (ASD)
Many children with autism experience sensory processing differences, communication difficulties and increased sensitivity to environmental stimuli.
Exposure to vape aerosols may worsen sensory discomfort caused by strong smells or airborne irritants.
Respiratory irritation can also contribute to behavioural challenges, including increased agitation, irritability or difficulties with self-regulation.
Furthermore, emerging research highlights the importance of healthy brain development in children with autism.
Any environmental factor that may negatively influence neurological functioning deserves careful consideration.
2. Children with Attention Deficit Hyperactivity Disorder (ADHD)
Children with ADHD often struggle with attention, impulse control and behavioural regulation.
Since nicotine affects the brain's neurotransmitter systems, passive exposure may potentially complicate existing attention and behavioural challenges.
Although more research is needed, healthcare professionals generally recommend minimising children's exposure to nicotine-containing environments whenever possible.
3. Children with asthma and chronic respiratory conditions
Children with asthma are among the most vulnerable groups.
Exposure to vape aerosols can trigger asthma symptoms, including coughing, wheezing, chest tightness and breathing difficulties.
Repeated exposure may increase reliance on medications, emergency medical visits and reduce participation in physical activities. For these children, maintaining clean indoor air is essential.
4. Children with cerebral palsy and neuromuscular disorders
Some children with cerebral palsy and neuromuscular conditions already experience challenges with breathing, swallowing and airway protection. Exposure to airborne irritants may place additional strain on their respiratory systems.
Even mild respiratory illnesses can have a greater impact on children with compromised motor function, making prevention especially important.
5. Children with intellectual disabilities
Children with intellectual disabilities may have difficulty understanding environmental health risks or communicating symptoms clearly. Caregivers may not immediately recognise signs of respiratory irritation or discomfort.
For these children, creating a smoke-free and vape-free environment is a simple yet effective protective measure.
Effects beyond the home
Many people assume that vaping near an open window or in another room provides adequate protection.
However, the vape particles can travel throughout the indoor environments and settle on furniture, clothing, curtains, toys and other household surfaces.
Children may then encounter these residues through touching surfaces and placing objects or hands in their mouths.
This third-hand exposure represents another pathway through which harmful substances may reach young children.
Schools, childcare centres, playgrounds and community facilities should also remain vigilant about maintaining vape-free environments to protect children's health.
What parents and caregivers can do
Several practical steps can reduce children's exposure to passive vaping:
> Make homes completely vape-free and smoke-free.
> Never vape inside vehicles, even when windows are open.
> Avoid vaping near children in outdoor settings.
> Educate family members about the health risks of passive vaping.
> Seek professional support for smoking or vaping cessation when needed.
> Encourage schools and community centres to maintain strict vape-free policies.
> Store vaping devices and refill liquids securely away from children.
A shared responsibility
Every child deserves access to clean air.
While vaping is often promoted as a less harmful alternative to traditional smoking for adults, this does not mean it is risk-free for children.
Passive exposure to vape aerosols may affect respiratory health, brain development, immune function and overall well-being.
For children with special needs, including ASD, ADHD, cerebral palsy, intellectual disabilities and asthma, the risks may be even greater due to existing developmental or medical vulnerabilities.
Protecting these children requires awareness, education and responsible behaviour from parents, caregivers, schools, healthcare professionals and policymakers.
As society continues to navigate the growing popularity of vaping, one principle should remain clear: Children should never be exposed to substances that may compromise their health and development.
Creating vape-free environments is not simply a personal choice; it is a public responsibility that helps ensure every child has the opportunity to grow, learn, communicate and thrive without a compromised breathing environment.
Initiatives in South-East Asia
E-cigarettes are banned in Brunei Darussalam. The country completely bans the import, distribution, sale and use of all electronic cigarettes and vaping devices
There are strict public restrictions on vaping in all areas such as public buildings, workplaces and near smoke-free zones.
By safeguarding children from passive vaping today, we invest in a healthier, stronger and more resilient generation tomorrow.
