Thirdhand smoke can cause cancer: Study

While secondhand smoke had long been known to have cancer-causing properties, a new study reports thirdhand smoke has the same effects.

"Smoking outside is better than smoking indoors but nicotine residues will stick to a smoker's skin and clothing," said lead researcher Lara Gundel.

According to the study published in PNAS, substantial levels of toxins are found on smoke-exposed material long after the cigarette has been put out.

Nicotine stains on clothing, furniture and wallpaper react with indoor pollutants to form dangerous chemicals known as tobacco-specific nitrosamines (TSNAs), one of the most potent carcinogens found in unburned tobacco and tobacco smoke.

Nitrous acid — the main pollutant emitted from car exhaust — boosts TSNA levels found on contaminated surfaces by tenfold, the study reported.

Dermal uptake of the nicotine is highest in children, making them the most vulnerable population to the health risks of thirdhand smoke.
