World No Tobacco Day | Children most vulnerable to thirdhand smoke: Experts

New Delhi, May 30: Children are most vulnerable to third-hand smoke pollutants that settle indoors when tobacco is smoked, said health experts on Thursday, ahead of World No Tobacco Day.

World No Tobacco Day is observed every year on May 31 to raise awareness about the health risks of using tobacco.

Thirdhand smoke contains more than 250 residual chemicals including nicotine and cancer-causing substances such as formaldehyde, and naphthalene. It builds up on surfaces over time and can get embedded in clothing, furniture, drapes, bedding, and carpets. "Children are most vulnerable to thirdhand smoke because they tend to touch surfaces, and often their mouths, resulting in skin exposure and ingestion of these residues," Lancelot Mark Pinto, from P. D. Hinduja Hospital & MRC, Mumbai, told IANS.

"The only way to prevent such exposure is by completely banning indoor smoking, and insisting on keeping a radius outside buildings and homes smoke-free," added Lancelot, Consultant Pulmonologist and Epidemiologist at Hinduja.

Thirdhand smoke is a hidden danger, lingering in furniture, walls, and clothing long after a cigarette is extinguished. The residue can remain for weeks, months, or even years.
