Smoking remains prevalent in the Middle East, with Tel Aviv resembling 1980s Paris in terms of smoking culture. The use of hookahs and shisha pipes is widespread, despite the health risks associated with tobacco smoke. The growing popularity of vaping has also become a global phenomenon. However, new research has highlighted the dangers of thirdhand smoke, a toxic residue that can persist on indoor surfaces long after the smoke has cleared.
Thirdhand smoke consists of harmful tobacco by-products that linger on furniture, décor, walls, and floors, posing a health risk to inhabitants of the space. Even ceremonial tobacco use, such as within certain Native American cultures, can leave behind these toxic residues.
A recent study, published in the Journal of Exposure Science & Environmental Epidemiology, found that indoor surfaces in smoking households, where children live, are contaminated with nicotine and the carcinogen NNK from tobacco smoke. According to the study’s lead researcher, Ashley Merianos of the University of Cincinnati, these findings are alarming.
The study revealed the presence of nicotine on surfaces in all the children’s homes, with nearly half of the homes showing significant levels of the carcinogen NNK. The researchers also found that NNK levels on surfaces and vacuumed dust were comparable, indicating that surfaces can serve as a source of thirdhand smoke exposure for children.

According to Merianos, lower-income households and homes that do not have a complete ban on indoor smoking showed higher levels of NNK and nicotine on surfaces. Even homes with voluntary indoor smoking bans still had detectable amounts of these toxic substances. This highlights the need for increased awareness and policy interventions to protect children from the dangers of thirdhand smoke.
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 emphasizes that home smoking bans do not entirely safeguard children and their families from the harmful effects of tobacco smoke. The study’s results underscore the persistence of thirdhand smoke pollutants in children’s homes, posing a serious health risk.
