Many know of the harms and health risks of smoking and secondhand smoke 

However, you may not have heard of thirdhand smoke, which is the chemical pollutants that linger and settle indoors after tobacco is smoked.  

“The chemicals in thirdhand smoke include nicotine as well as cancer-causing substances such as formaldehyde, naphthalene and others,” according to the Mayo Clinic. 

Policy gaps are failing to protect the public from thirdhand smoke, according to a recent study. 

The study suggests that policies safeguard against thirdhand smoke even as they protect against secondhand smoke exposure by prohibiting indoor smoking in public places. 

“While these measures have been instrumental in protecting public health, saving lives, and reducing health care spending by billions of dollars, the researchers say they lack critical safeguards against thirdhand smoke,” according to the recent study. 

Let’s dig deeper into the researcher’s suggestions and how you can quit smoking!  

How Does Thirdhand Smoke Impact People? 

The recent study, led by researchers from Diego State University and the University of California, San Francisco, analyzed policies aimed to protect against thirdhand smoke. 

Thirdhand smoke contains more than 250 chemicals. 

The residue of thirdhand smoke is also hard to eliminate or “air out” and cannot be removed by opening windows, air conditioning, or traditional household cleaning. 

“[Thirdhand smoke] adheres to surfaces, accumulates in dust, and infiltrates building materials, furniture, carpets, and clothing, allowing it to linger for years in buildings and cars even after the smoking has stopped,” according to the recent study 

Also, thirdhand smoke can be a health hazard for many, especially children and toddlers, who are often crawling and putting non-foods in their mouths. 

“Thirdhand smoke disproportionately affects already vulnerable populations, with children, older individuals and those with compromised immune systems most likely to be exposed,” according to the recent study 

This can deeply impact many Latinos who suffer disproportionately from health issues like diabetes and heart disease.   

“The nicotine in tobacco smoke reacts with nitrous acid – a common component of indoor air – to form the hazardous carcinogens. Nicotine remains on surfaces for days and weeks, so the carcinogens continue to be created over time, which are then inhaled, absorbed or ingested,” according to the American Nonsmokers’ Rights Foundation. 

How Can Policy Protect People Against Thirdhand Smoke? 

Researchers from the Thirdhand Smoke Research Consortium recommend several policy changes in relation to public health, including:  

 

  • Redefine smoke-free as free of tobacco smoke pollutants from secondhand and thirdhand smoke. 
  • Adopt comprehensive indoor smoking bans and eliminate exceptions. 
  • Identify thirdhand smoke-polluted indoor environments. 
  • Remediate thirdhand smoke pollution. 

“Only by including thirdhand smoke in our smoke-free policies can we fully protect people from the toxic legacy of tobacco use in indoor environments,” said recent study leader Georg Matt of San Diego State University.
