Vaping, considered a safer substitute for smoking, is not entirely safe. Just like secondhand smoking, the risks of vaping also extend beyond the person using it. Third-hand vaping possess a silent yet significant health threat. It occurs when toxic substances from e-cigarettes fall and remain on surfaces, making children and other vulnerable people prone to harmful health effects.

It’s important to understand how vaping impacts the environment and those around you, says Dr Amit Sakaria, MD, Internal Medicine, Senior Consultant Physician, Ruby Hall Clinic Wanowarie. “When chemicals from e-cigarette aerosols linger on surfaces like furniture, walls, carpets, and even clothing, the residues can stick around long after vaping has stopped. When it comes to contact with a person it is referred to as third-hand vaping,” he says.

The vapour from e-cigarettes, he explains, contains nicotine and also heavy metals like lead, chromium, and nickel, along with volatile organic compounds (VOCs). “These particles settle on surfaces and can linger for weeks or months. Children, especially toddlers, are more likely to come into contact with these chemicals as they crawl on the floor, touch objects, and put their hands in their mouths,” Dr Sakaria adds. Even soft surfaces like sofas and clothes can trap these chemicals, posing a risk of toxic exposure through touch and ingestion.

Hazards of third-hand vaping:

The residues left behind by vaping are harmful. “The nicotine from the residue may remain on surfaces for a longer period and may react with other chemicals in the air and form harmful compounds. According to Dr Sakaria those children who are exposed to such compounds may experience a higher risk of respiratory problems, skin irritation and toxic ingestion,” Dr Sakaria says.

Moreover, heavy metals found in e-cigarette vapour can collect on surfaces and pose long-term health risks. “Volatile organic compounds (VOCs) from e-cigarette aerosols can irritate the eyes, nose, and throat, while also having carcinogenic effects. Pregnant women exposed to these chemicals may also experience adverse health effects, which could impact fetal development. Individuals with asthma or respiratory conditions are especially vulnerable, as third-hand exposure can worsen symptoms and trigger health complications,” shares Dr Sakaria.

Tips to reduce third-hand vaping:

You can minimise the risks of third-hand vaping by following a few effective strategies. “Create a smoke-free zone, especially indoors and inside cars. Regular cleaning of surfaces is essential to prevent chemical buildup. Washing clothes, bedding, and curtains frequently can help eliminate trapped toxins. Besides, deep cleaning carpets, upholstery, and hard surfaces with appropriate cleaning solutions can further reduce residue. Installing air purifiers with HEPA filters can also help remove pollutants from the air. Good ventilation in homes and cars plays a key role in preventing the accumulation of harmful chemicals,” he says.
