It should be understood that smoking is not only harmful to the active and passive smokers. A recent study states that third parties who do not intentionally consume secondhand cigarette smoke also be affected. Thus, the adverse effects of smoking is actually a chain.
Lara Gundel, a scientist at Lawrence Berkeley National Laboratory suggests, secondhand cigarette smoke on a third person could still cause mutagenic. Nitrosamines, one of the toxic substances in tobacco, the substances are carcinogenic when it gets into the body.
“Nitrosamines are living on the surface, and when it exists on the surface of clothes or carpets, it is a very danger to children,” said Gundel.
Third parties who obtain these toxins are not directly inhaled the smoke. Smoke or cigarette butts sometimes accidentally stuck to the surface of an object. For example, shirts, pants, or table. The attachment carries most of the toxins in cigarettes. When there are people in contact with secondhand smoke that stuck earlier, then there is an opportunity to bring these poisons into the body. Eventually, the person is exposed to bad smoking.
Worse, a third person who exposed to cigarette is still possible to experience DNA damage. Body cells would be problematic and could worsen the condition over time.
Quoted from the Huffington Post, the researchers put the strips of paper in a room full of cigarette smoke. Some strips of paper are left exposed to the fumes and chemicals from cigarette smoke, which is equivalent to a puff of smoke five cigarettes for 20 minutes in an open space. While in the other room, the paper strips were left exposed to cigarette smoke exposure up to 25 minutes with a well-ventilated area.
The toxic compounds in a strip of paper known to have higher levels when placed in a smoky room for longer. Paper strips were then faced with human cells for 24 hours straight. From there found, human cells undergo oxidative DNA damage, and is equivalent to turning off the chains of DNA.
“The findings of this study demonstrate for the first time that exposure to THS (thirdhand smoke) is genotoxic in human cell lines,” wrote the researchers. “Genotoxicity is the perpetrator (or factors) that is known in the development of cancer and other diseases caused by cigarette smoke,” said the researcher, this research was published in the journal Mutagenesis.
