Silent threat: Risks attached with passive smoking

Sowmya Raju | NT

Bengaluru: Passive smoking, also known as secondhand smoke (SHS) exposure, is not just a concern for smokers; it poses a significant threat to the health and well-being of non-smokers as well.

In India, recent data indicates that a substantial portion of the population, around 38.7% of adults, encounters SHS either at home or in workplace settings.

Additionally, public places, such as restaurants and public transportation, along with enclosed spaces, expose a significant percentage of the youth (21% of those aged 13-15) to secondhand smoke.

The consequences of this exposure are profound, contributing to an estimated 200,000 deaths annually, representing 27% of all cancer-related fatalities in the country.

The economic burden is equally staggering, with a direct cost estimated at Rs. 567 billion (over US$ 7 billion) for individuals aged 15 and above. 

A silent threat to non-smokers

Dr Sunil Kumar K, Lead Consultant - Interventional Pulmonology at Aster CMI Hospital, Bengaluru said, “Passive smoking poses significant health risks for nonsmokers, subjecting them to the detrimental effects of secondhand smoke. The dangers are theoretical and have tangible consequences on one's well-being.”

He added respiratory issues, including asthma, bronchitis, and pneumonia, are among the immediate consequences.

Cardiovascular complications, such as heart disease and stroke, are heightened due to the toxic components of cigarette smoke.

The risk of cancer, particularly lung cancer in non-smokers, is another alarming aspect. Beyond physical health, passive smoking may impair cognitive function and increase the risk of neurodegenerative diseases.

Dr Sunil Kumar added, “ Children exposed to secondhand smoke are at greater risk for sudden infant death syndrome (SIDS), low birth weight, and developmental issues.”

Smoke-free strategies for health

To mitigate these risks, Dr. Sunil Kumar K suggests several precautions.

He suggested, “Stay away from places where smoking is allowed, and designate smokefree zones in homes and workplaces.”

Individuals should actively avoid places where smoking is allowed and advocate for smokefree zones in both homes and workplaces. In situations where exposure is unavoidable, wearing masks can help reduce inhalation of harmful smoke particles.

He urges people to ensure proper ventilation in indoor spaces, which is crucial to dilute and disperse the smoke effectively.

Advocacy for smoke-free environments is essential, encouraging and supporting policies that promote healthier public spaces for everyone.

Open communication with smokers about the importance of a smoke-free environment can also contribute to creating awareness and fostering a healthier lifestyle.

Dr Sunil Kumar K explained that, “Understanding the risks associated with passive smoking and adopting these precautions can lead to a healthier, smoke-free lifestyle for nonsmokers. By taking these steps, individuals can protect themselves and others from the detrimental effects of secondhand smoke, contributing to a healthier society overall.”

It's imperative to raise awareness about the often overlooked risks of passive smoking, fostering a collective effort towards creating smoke-free environments for everyone's well-being.
