I appreciate to arise these important issue. I want to share of my collection of data and information about it.


The process of breathing other people's smoke is called 'passive smoking'.
What's in second-hand smoke?

Second-hand smoke contains a mix of more than 4000 chemicals, including ingredients found in products such as paint stripper (acetone), toilet cleaner (ammonia), rat poison (cyanide), insecticide (DDT) and car exhaust fumes (carbon monoxide).

Many of these chemicals are present in higher concentrations in sidestream smoke than in the mainstream smoke that the smoker inhales. Nearly 85 per cent of the smoke in a room results from sidestream smoke.

At least 50 of the 4000 chemicals found in second-hand smoke are known to cause cancer, including hydrogen cyanide, arsenic, formaldehyde and sulphur dioxide.

How does second-hand smoke affect non-smokers?

Some of the immediate effects of being exposed to second-hand smoke can include eye irritation, headache, cough, sore throat, dizziness and nausea. Adults with asthma can also experience a significant decline in lung function when exposed to second-hand smoke.

Short-term exposure to tobacco smoke also has a measurable effect on the heart in non-smokers. Just 30 minutes of exposure is enough to reduce blood flow to the heart.

In the longer term, second-hand smoke exposure has been shown to increase the risk of developing a range of smoking-related illnesses. These include lung cancer, heart disease, stroke, respiratory illnesses, and many childhood illnesses.

Lung cancer
The link between second-hand smoke exposure and lung cancer has been established since the mid-1980s. Studies have shown that non-smokers exposed to second-hand smoke have around a 20 per cent increased risk of developing lung cancer. The more they inhale, the higher the risk.

Heart disease

An association between heart disease and second-hand smoke exposure was found in the early 1990s. At that time it was estimated that heart disease caused by second-hand smoke was the third leading cause of preventable death in the USA.

In New Zealand it has been estimated that around 240 people die and 1200 are admitted to hospital every year as a result of heart disease relating to second-hand smoke exposure.

Studies have shown that non-smokers have a 23 per cent increased risk of developing heart disease when living with a smoker. This risk does not relate to the quantity of second-hand smoke inhaled - even short periods of exposure can increase heart disease risk.

     As little as five minutes of exposure to second-hand smoke can stiffen the aorta, making the heart work harder to pump blood.
    The cell linings of the coronary arteries of non-smokers can be affected by as little as 30 minutes of exposure, increasing the likelihood of fat deposits building up in the arteries. 
    For people with coronary heart disease, increased carbon monoxide levels caused by short-term exposure to second-hand smoke can trigger rapid onset of angina.

While the risk of heart disease in non-smokers exposed to second-hand smoke is large, research does suggest that early damage to arteries caused by second-hand smoke may be reversible if second-hand smoke is avoided for two years.

Stroke
Findings of a New Zealand study suggest that long-term sustained exposure to second-hand smoke increases non-smokers' stroke risk by around 82 per cent. Each year in this country about 85 people die and 500 are admitted to hospital as a result of strokes relating to second-hand smoke exposure.

Respiratory illnesses
The link between respiratory illnesses and exposure to second-hand smoke is well-documented. Some of the subtle but significant effects of second-hand smoke exposure on respiratory health include increased coughing, phlegm production, chest discomfort and reduced lung function.

For people with asthma, exposure to second-hand smoke can cause asthma attacks, increased sensitivity and reduced lung function, as well as irritation of the eyes, nose and throat. Research has also shown that adults exposed to second-hand smoke at home or in the workplace have a 40-60 per cent increased risk of asthma compared with people who are not exposed in these places.

Childhood illnesses
Young children are particularly vulnerable to the harmful effects of second-hand smoke exposure. In young children exposure to second-hand smoke is linked to increased risk of middle ear disease, lower respiratory illnesses (croup, bronchitis, bronchiolitis and pneumonia), the onset of asthma and worsening of asthmatic symptoms, and reduced lung growth.

In addition, exposure to second-hand smoke through maternal smoking has been shown to cause sudden infant death syndrome (SIDS, or cot death). It has been estimated that 50 New Zealand babies die every year from SIDS caused by second-hand smoke exposure.
Deaths and hospitalisations from second-hand smoke

A recent New Zealand study found that people who had never smoked and lived with smokers had a mortality (death) rate that was around 15 per cent higher than the mortality rate of those who lived in a smokefree household.

Exposure to second-hand smoke has been estimated to cause around 350 deaths of New Zealanders every year and be responsible for around 3,200 hospitalizations.

Allow me to inform you something about this:


What's in secondhand smoke?

Secondhand smoke — also known as environmental tobacco smoke — includes the smoke that a smoker exhales (mainstream smoke) and the smoke that comes directly from the burning tobacco product (sidestream smoke). Secondhand smoke contains thousands of toxic chemicals, including:

Benzene
Carbon monoxide
Chromium
Cyanide
Formaldehyde
Lead
Nickel
Polonium

The dangerous particles in secondhand smoke can linger in the air for hours. Breathing secondhand smoke for a short time can irritate your lungs and reduce the amount of oxygen in your blood. Prolonged or repeated exposure to secondhand smoke is all the more dangerous. And it isn't just the smoke that's a concern. The residue that clings to a smoker's hair and clothing, as well as cushions, carpeting and other goods — sometimes referred to as thirdhand smoke — also can pose risks, especially for children.

Secondhand smoke: Avoid dangers in the air

How risky is secondhand smoke?

Secondhand smoke causes or contributes to serious health problems, including:

Lung disease. Asthma, bronchitis and other chronic lung ailments can be triggered or aggravated by exposure to secondhand smoke.
Heart disease. Secondhand smoke increases the risk of heart attack and other heart problems. Secondhand smoke also damages blood vessels, interferes with circulation and increases the risk of blood clots.
Cancer. Secondhand smoke is a known risk factor for lung cancer. Some research also suggests a link between secondhand smoke and various other types of cancer.

Secondhand smoke poses additional risks for children, who are especially vulnerable to the effects of secondhand smoke. Problems include:

Low birth weight. Exposure to secondhand smoke during pregnancy increases the risk of low birth weight.
Sudden infant death syndrome (SIDS). Secondhand smoke increases the risk of SIDS — whether exposure occurs during pregnancy or after birth.
Infections. Children who live with smokers are more likely to develop middle ear infections (otitis media) and lower respiratory tract infections.
Secondhand smoke also causes chronic coughing, phlegm and wheezing, as well as eye and nose irritation.

How can secondhand smoke be avoided?

With planning, you can reduce or eliminate exposure to secondhand smoke. Start with these simple steps:

Don't allow smoking in your home. If family members or guests want to smoke, ask them to step outside. Don't rely on an air conditioner, ventilation system or an open window to clear the air.
Don't allow smoking in your vehicle. If a passenger must smoke on the road, stop at a rest stop for a smoke break outside the car.
Insist that smoking restrictions be enforced in your workplace. Even powerful ventilation fans don't effectively remove secondhand smoke from the air.
Choose smoke-free care facilities. If you take your children to a child care provider, choose one with a no-smoking policy. The same goes for aging loved ones. If they live in a long term care facility, make sure it's smoke-free.
Patronize businesses with no-smoking policies. Many restaurants and other establishments are entirely smoke-free. Reinforce these no-smoking policies by telling the management that you appreciate the healthy air.
Keep your distance from smokers. If you must share space with people who are smoking, sit as far away from them as possible.

If you have a partner or other loved one who smokes, offer support and encouragement to stop smoking. The entire family will reap the benefits.

Smoking is a very bad habit. It just waste our money and it not good for our health. So please avoid the smoking.
