What Is Third Hand Smoke?
Have you ever smelled a smoker's hair or hand? Have you ever been able to tell that the person next to you on the bus is a smoker because he reeks like an ashtray? How about stepped into an elevator and been able to tell through a faint whiff in the air that a smoker had recently ridden in the elevator? Or checked into a non-smoking room in a hotel only to know that someone had broken that no-smoking rule?
If you answered yes to any of these scenarios, then you have experienced third-hand smoke.
First-hand smoke is what a smoker inhales. Second-hand smoke is what everyone around that person inhales when he or she is smoking, and smoke is visible in the air. Both of these are well-documented and widely accepted to be dangerous and to pose myriad public health risks.
Now researchers are saying that third-hand smoke exists, and that toxins in that third-hand smoke lingers longer than anyone realized — months and even as much as a year in some cases. More alarming, babies and children seem more susceptible to third-hand smoke than adults do, in part because children are smaller so a little toxicity means greater contamination, and also because babies and kids are constantly putting things in their mouths, including their hands.
Third-hand smoke has all the same toxins as first- and second-hand smoke, and it is considered more dangerous than everyday toxins in the air like car exhaust. Cigarette smoke has over 250 toxins in it, including such obviously dangerous compounds as lead, arsenic, cyanide, butane and carbon monoxide.
These poisons found in tobacco smoke are particularly dangerous to children, as developing brains are susceptible to even low levels of toxins. There's a reason why old houses with ancient lead paint remnants are still considered dangerous to children.
First- and second-hand smoke exposure have been shown to result in lower IQs.
Is Third Hand Smoke Dangerous?
While scientists and doctors determined years ago that third-hand smoke exists and can linger on furniture, on walls and in the air longer than anyone previously thought, there haven't yet been any conclusive studies on the health effects of third-hand smoke — the tobacco smoke contamination that exists after a cigarette has been put out.
Because there are toxins present in third-hand smoke, and because first- and second-hand smoke has been proven to cause heart disease and other health problems, doctors believe that third-hand smoke is dangerous, especially to babies and children. But there is no evidence that this is so.
This will be an area of greater study in coming years as doctors seek to prove what they believe is a public health threat.
Not everyone believes in third-hand smoke, or that it is a real health threat
How Can I protect My Children From Third-Hand SMoke?
The best way to protect your children from third-hand smoke is to make sure that nobody in your household smokes. Third-hand smoke and its potential dangers are a great reason to quit smoking!
If you have successfully quit smoking, have a professional cleaning service like COIT to come in and deep clean your furniture, upholstery, curtains and rugs. If you have been a heavy smoker and can afford it, consider buying new rugs. And be sure to wash all your clothes and shoes.
If you move into a house where a smoker used to live, repaint the walls. A fresh coat of paint can't completely cover third-hand smoke, but it's an extra barrier that can't hurt.
Keep your children from going to friends houses where somebody in the household smokes.
