Smoking is still a big deal in the Middle East. Tel Aviv smokes like Paris in the 80s, and the hookah and shisha pipe is going strong in every city where the taste of apple tobacco makes you forget that the smoke is bad for your lungs. Vaping is pretty much everywhere in the world. Parents typically shoo the kids outside or smoke on the balcony but the residue from smoking can also do harm, finds a new study, citing third-hand smoke.
Thirdhand smoke is the presence of toxic tobacco by-products that remain on surfaces such as furniture, décor, walls and floors. It does not matter of the tobacco is organic. Some cultures like Native Americans may use tobacco for ceremonial purposes.
In a new study, published in the Journal of Exposure Science & Environmental Epidemiology, researchers tested the surfaces in smoking households where children reside and found troubling results, says Ashley Merianos, a tobacco researcher at the University of Cincinnati who led the study.
Researchers found nicotine on surfaces in all of the children’s homes and detected the presence of a tobacco-specific carcinogen (called NNK) in nearly half of the homes, she says. The study reported that the NNK levels on surfaces and vacuumed dust were similar, which Merianos says indicates that surfaces and dust can be similar reservoirs and sources of thirdhand smoke exposure for children.

“This is critically important and concerning, since NNK is considered the most potent carcinogen for tobacco-induced cancers,” says Merianos, an associate professor in UC’s School of Human Services.
Nicotine affects poorer families
- Children living in lower-income households had higher levels of NNK and nicotine found on home surfaces.
- Children living in homes that did not ban indoor smoking had higher levels of NNK and nicotine found on surfaces.
Merianos says that NNK and nicotine were still detected in homes with voluntary indoor smoking bans, which highlights the persistence of thirdhand smoke pollutants on surfaces in children’s homes: “This research highlights that home smoking bans do not fully protect children and their families from the dangers of tobacco,” she adds.
