It’s no secret that doctors are continuously warning about the dangers that cigarettes pose. Secondhand smoke is also very dangerous, which people who are not smokers inhale from smokers. Now, experts are detailing how dangerous thirdhand smoke also is, which means the residuals chemicals that cigarette smoke leaves on indoor surfaces. A growing body of evidence is showing that this dangerous residue remains on objects for months after the smoke is gone. It can be absorbed through the skin, inhaled or even ingested.
There has been evidence of the dangers of thirdhand smoke found in casinos and experiments on mice have shown just how hazardous it is. Now, a study which the journal Science Advances recently published says that outdoor tobacco smoke can travel inside and coat the objects in there. Often, these dangerous chemicals become airborne once more and can also travel inside buildings via central air conditioning systems. According to Peter DeCarlo, the leader of this new study, even if you are inside a non-smoking environment you might still be exposed to tobacco residue. A hotel room, a taxi, even a classroom, where people don’t usually smoke, are dangerous.
The dangers of thirdhand smoke
In order to reach this conclusion, DeCarlo collaborated with an indoor air expert at Drexel, Michael Waring. They ran a series of tests inside a classroom, including pumping outdoor air in and out of the room. This was how they found that tobacco smoke can travel to indoor spaces and coat the objects inside. In the summer, when the air conditioning systems are working, the residue become airborne once more, making the residual smoke even more dangerous.
This is another example of just how hazardous thirdhand smoke actually is, even if not many people know about it. People are a lot more aware of secondhand smoking and normal smoking. This just proves that they should be more careful about thirdhand smoke too.
