Parents who smoke often open a window or turn on a fan to clear the air of second-hand smoke, but experts now have identified another smoking-related threat to children’s health that isn’t as easy to get rid of: third-hand smoke.
That’s the term being used to describe the invisible yet toxic brew of gases and particles clinging to smokers’ hair and clothing, not to mention cushions and carpeting, that lingers long after smoke has cleared from a room. The residue includes heavy metals, carcinogens and even radioactive materials that young children can get on their hands and ingest, especially if they’re crawling or playing on the floor.
Scents are Not What They Seem
Since World War II we have embraced man-made chemicals for use in almost all aspects of our lives. Using materials such as oil, coal, and natural gas, scientists continue to synthesize many never-before-in-existence chemicals and chemically based materials. We use them to fill our needs for everything from medicines to fabrics, fertilizers to building materials and from perfume to space shuttle parts. The American Food and Drug Administration (FDA) gets applications for evaluation of an average of 50 new, man-made chemicals per day. This rate far surpasses the ability to adequately test all of these chemicals for their safety to humans or the natural environment.
Volatile Organic Compounds, or VOCs, is a very large family of chemicals which includes all the organic compounds containing carbon, and which readily evaporate into the air. Although most are liquids at room temperature, they will easily enter air, and they greatly contribute to air pollution. Man-made fragrance chemicals are part of the category of VOCs.

your forgetting the fifth hand smoke which is the smoke hat blows out the window and onto the ground for you to walk on and carry into your home where your cat will pick it up and transfer it onto your bed for you to in hale......

It's when a fly lands on your residue covered window or wall..inhales the Third Hand Smoke... then lands on your baby's face and exhales into the baby's mouth.
tis true.
it's science.

My husband told me years ago that Penn and Teller did a BS episode on second hand smoke where they claimed second hand smoking was not a danger and was in fact just a myth. I didn't see the episode so I don't know what they were basing their info on but maybe one of you saw it and can fill us in.

Edit to add: Did anyone see that news article about the town in Colorado that issued a smoking ban, and after three years experienced a 41% drop in heart attacks? It was the longest run study on second-hand smoke effects and really showed the correlation between cigarette smoke and heart failure.
A smoking ban in one Colorado city led to a dramatic drop in heart attack hospitalizations within three years, a sign of just how serious a health threat secondhand smoke is, government researchers said Wednesday. The study, the longest-running of its kind, showed the rate of hospitalized cases dropped 41 percent in the three years after the ban of workplace smoking in Pueblo, Colo., took effect. There was no such drop in two neighboring areas, and researchers believe it's a clear sign the ban was responsible.
The study suggests that secondhand smoke may be a terrible and under-recognized cause of heart attack deaths in this country, said one of its authors, Terry Pechacek of the U.S. Centers for Disease Control and Prevention.
At least eight earlier studies have linked smoking bans to decreased heart attacks, but none ran as long as three years.

In Pueblo, the rate of heart attacks dropped from 257 per 100,000 people before the ban to 152 per 100,000 in the three years afterward.
The findings in this report are subject to at least four limitations. First, because no data were available on whether study subjects were nonsmokers or smokers, determining what portion of the observed decrease in hospitalizations was attributable to reduced SHS exposure among nonsmokers and what portion was attributable to increased quitting among smokers was not possible.

Second, the study did not directly document reductions in SHS exposure among nonsmokers
