Researchers have discovered that thirdhand smoke poses a greater risk to children than to adults, even in homes where no one smokes. A recent study by experts from San Diego State University (SDSU) and the University of Cincinnati revealed that despite frequent handwashing, children’s hands can still harbor harmful substances. Specifically, the study highlights the presence of thirdhand smoke (THS), which consists of the residue that remains on surfaces and in dust wherever tobacco has been used. Kids are exposed to THS by touching these contaminated surfaces and inhaling the chemicals that off-gas from them.
In this study, researchers swabbed the hands of 504 children aged 11 and younger, including those seeking emergency services at Cincinnati Children’s Hospital Medical Center and the children of hospital staff. Alarmingly, about 97% of the participants showed some level of nicotine on their hands. This wasn’t exclusive to kids from smoking households; a staggering 95% of children from non-smoking homes also tested positive for tobacco traces.
The findings indicate that the risks associated with thirdhand smoke are more widespread than previously understood. While most are familiar with the concept of secondhand smoke, thirdhand smoke can linger in any room where smoking or vaping has occurred, affecting children even when they are not directly exposed to smoke.
“This study addressed a significant gap in research. We have extensively studied thirdhand smoke in private homes, vehicles, and public places, but we lacked data from clinical populations,” stated Dr. Emily Carter, a psychology professor at SDSU and director of the Thirdhand Smoke Resource Center.
On a more positive note, the researchers found that targeted educational efforts to reduce tobacco exposure among at-risk children have proven effective. Parents who actively work to minimize their children’s exposure to tobacco were able to reduce nicotine levels on their kids’ hands by an average of 86%.
Interestingly, the levels of nicotine detected varied based on household income and ethnicity, with children from lower-income families more likely to have tobacco residue on their hands compared to their wealthier peers. “The link between income and nicotine presence, regardless of other factors, suggests a concerning role of income-related disparities, such as housing conditions, in THS exposure,” the study’s authors remarked.
To protect children from THS, the researchers recommended implementing smoking bans, conducting exposure screenings, and remediating THS in homes between tenant changes.
