Third hand smoke and its concerns

By on April 29, 2013

Thanks to the initiatives of the Government of India and various non-government organizations (NGO) in context of spreading mass awareness on detrimental impacts of cigarette smoking. Today even the kids are well aware that cigarette smoking is injurious to health. However, another side of the coin shows that these initiatives have definitely enhanced awareness among people, but it would not be correct to say that this awareness has motivated smokers to leave smoking.

What do you breathe?

Concerns regarding smoking are justified on the ground that a smoker not only plays with his own health, but also with the health of everybody who comes into contact with cigarette smoke. Safeguarding the citizens against passive smoking or the exposure to second hand smoke has also been a subject of concern for the government (World Health Organization). The increasing awareness among people about the deadly impacts of second hand smoke and the government’s initiatives regarding putting a ban on smoking at public places is a worthwhile step in this direction. But this doesn’t mean that by not smoking in front of others will protect them from the toxic smoke of cigarette. There is another threat from cigarette smoke; the third hand smoke (The Times of India dated May 30, 2010). An article in the Indian Express revealed that awareness about third hand smoke is very low.

What is third hand smoke?

Third hand smoke, as it is often called, is also known by the names, tertiary smoke and aged smoke. Third hand smoke is the smoke that remains even after months in air, dust, and surfaces of the place where smoking has been done. This fact has been confirmed by Matt (2010) through a study where they concluded that even if the smoker’s home remains vacant for two months in a stretch and is regularly cleaned, third hand smoke still exists in the air and dust, and on the surfaces like furniture, curtains, bed sheets and carpet of that home. Third hand smoke also gets trapped into the hair, skin as well as clothes of the smoker and therefore anybody that comes into contact with the smoker or the place where smoking was done even months ago suffers the exposure of third hand smoke. Winickoff et al. (2008) provided about third hand smoke that this smoke remains long after the cigarette is extinguished.

Who are most prone to the impacts of third hand smoke?

The studies on this subject establish that infants and children are most prone to the dangers of third hand smoke. It is been established that children especially those who crawl on floor have a habit of getting their hands on everything lying on the floor and then putting these hands in the mouth. Roberts et al. (2009) claimed that infants and children are 100 times more sensitive to pollutants as compared to adults. The persons living in multi-dwelling units are also found to be highly prone to third hand smoking. This is because in an apartment kind of housing facility, it is almost impossible to escape from third hand smoke exposure if there are smokers in the neighborhood. Another study conducted by Los Angeles Bio-medical Research Institute (LA BioMed) highlighted the impacts of third hand smoke on unborn babies. The study claimed that third hand smoke negatively affects the lungs development of unborn babies and therefore recommended pregnant women to avoid any such places where smoking has ever been done in recent past.
