The risk of exposure to snuff does not end when you turn off the cigarette. It is well known the danger faced by passive smokers inhaling the smoke that surrounds them: no safe level of exposure. But what happens when white cloud that disappears? Not only is a bad smell in hair or clothes.

The residual cigarette smoke can also cause cancer. A new study, published in ‘Proceedings of the National Academy of Sciences’ ( ‘PNAS’), warning of what he calls “third-hand smoke”, ie, “residual [...] that nicotine has been absorbed by certain areas. It seems that it reacts with nitrous acid present in the environment and, as a result of this, form a kind of nitrosamines which are carcinogens.

In reaching this conclusion, experts from Lawrence Berkeley National Laboratory and the University of California at San Francisco (USA), took a series of samples in the truck drivers who had years of smoking over multiple paths and compared it with those obtained in the laboratory.

The cellulose used in various tests showed “presence of snuff-specific carcinogenic nitrosamines (TSNA, by its initials in English) 10 times,” the investigation, which recommended more attention to possible chemical reactions that can occur in the spaces. In fact, the environment may become more toxic over time and the largest accumulation of nicotine in rugs or carpet, for example.

Also this week, the prestigious journal Archives of Internal Medicine has published another work on the risks of environmental smoke in this case, is based on the risk faced by women exposed at home to bad fumes from their husbands .

After studying a cohort of almost 15,500 citizens of Hong Kong, non-smokers and aged between 65 and 74 years, scientists, led by Chi C. Leung and from different centers of that region in China, underscore the presence of a tight link between passive smoking and the diagnosis of tuberculosis. Some years ago, in 1996, a Spanish study came to a conclusion quite similar.

These data are particularly relevant in countries like China, where consumption of snuff is heavily unbalanced: 60% of men smoke, compared to 4% of women. Cigarettes, thus affecting the health of them silently. “Passive smoking accounted for 13.7% of active TB cases in this sample,” the work. This exposure can cause respiratory or other diseases including diabetes and coronary disorders, add a comment reported by the magazine cited the American Medical Association.

Two separate papers, as well as the editorial said, show two clear scientific evidence for banning the consumption of snuff in enclosed public places and on transport, and even at home. These are measures that protect the health of smokers, assets and liabilities, and that promote cessation of use of the former.
Letting her help

Besides cleaning the air, fighting this addiction is another major public health objectives of governments around the world. Advertising campaigns, education and proposals that support the financing of nicotine replacement therapies or specific drugs such as bupropion or varenicline. Precisely on this last topic concerns a new work, published in ‘PLoS Medicine’ and signed by an anti snuff guru, Simon Chapman.

The professor of Public Health, University of Sydney (Australia), among other charges has sustained the director of the journal Tobacco Control ‘, highlights that the majority of smokers who manages to overcome his habit will no more help than their willingness and effort.

In this sense, the paper denounces the strategy of a pharmaceutical industry bent on selling its product and, as a side effect is “medicalized” smoking. “The people lose confidence in their ability to change practices that are not healthy,” he adds.

“They should repeat smokers who spend withdrawal and gradually reduce consumption are the most common among those who manage to quit. Most were surprised to find that quitting is easy or somewhat difficult,” supports the controversial article.

No Smoking Signs are reading this, then you have already taken the first step. Thinking about how to quit smoking! The decision to stop smoking can seem overwhelming, but with help from this guide and support your family and friends can do it! Half of all people who have ever smoked have quit, so can you.

It can be very difficult to quit, but once you do, you’ll look better, smell better, feel better and be healthier!

Why should I quit?

Everyone knows that smoking can cause cancer when you get older, but did you know that also has negative effects on your body right now? A cigarette contains about 4000 chemicals, and at least 43 of the chemicals cause cancer in humans. Some of the other chemicals found in poisons. Some of the worst are:

* Nicotine: a deadly poison
* Arsenic: used in rat poison
* Methane: a component of rocket fuel
* Ammonia: found in floor cleaner
* Cadmium: used in batteries
* Carbon Monoxide: part of the toxic waste of the car
* Formaldehyde: used to preserve (keep in perfect condition) body tissues
* Butane: lighter fluid
* Hydrogen Cyanide: the poison used in gas chambers

Each time you inhale smoke from a cigarette, small amounts of these chemicals get into your blood through your lungs. They travel to all parts of your body, where they can cause damage.

Nicotine potentiates the carcinogenic effect of other substances from smoke snuff and the effects of carcinogens in the environment.

Nicotine acts on the mechanism of apoptosis, or cell death, preventing the cells to commit suicide. When it comes to cancer cells does the same thing which causes or encourages the formation of lung cancer.

In addition to snuff, there are other substances mentioned above which are listed now:

Asbestos: people who work with asbestos are seven times more likely to develop cancer than those who do not maintain contact with it. These people have a type of cancer called mesothelioma, which occurs in the pleura. In recent years, governments have banned the use of this material for commercial and industrial products. When combined with asbestos exposure to smoking, it increases their chances of getting cancer from 50 to 90 times.

Cancer-causing agents in the workplace: an occupational risk group are the miners. They work with materials that, when inhaled, can damage your lungs. Such substances are radioactive minerals such as uranium, and workers exposed to chemicals such as arsenic, vinyl chloride, nickel chromates, coal based products, mustard gas and chloromethyl ethers. People working in these conditions should be careful to avoid exposure to these agents.

Other factors would be those that have produced some damage to the lung and predispose them to cancer, as having suffered tuberculosis, silicosis or berilosis (diseases, the latter two, caused by inhalation of certain minerals).

Another reason that favors the growth of cancer cells would be the excess or deficit of vitamin A.

Noting the risk factors seem easy to prevent this disease. The no smoking or quit is the most effective measure in preventing cancer.
