Protect Yourself and Your Loved Ones

Thirdhand smoke (THS) is a term used to describe the residual contamination from tobacco smoke that lingers in rooms long after smoking stops and remains on our clothes after we leave a smoky place. It may seem merely like an offensive smell, but it is also indicative of the presence of tobacco toxins. Our fact sheet “Thirdhand Smoke in Apartments and Condos” provides more detailed information on the problem.

Thirdhand smoke consists of the tobacco residue from cigarettes, cigars, and other tobacco products that is left behind after smoking and builds up on surfaces and furnishings. Tobacco smoke is composed of numerous types of gasses and particulate matter, including carcinogens and heavy metals, like arsenic, lead, and cyanide. Sticky, highly toxic particulates, like nicotine, can cling to walls and ceilings. Gases can be absorbed into dust in a room, carpets, draperies, and other fabrics or upholsteries. A 2002 study found that these toxic brews can then re-emit back into the air and recombine to form harmful compounds that remain at high levels long after smoking has stopped occurring.

Further Research & Resources

Since 2002, further studies have contributed to the growing body of evidence that this lingering tobacco residue has significant health risks. Children and hospitality industry workers are especially at risk for  considerable exposure.  Studies of special note and resources include:
