Hi,
This is Neetu
You all Know that smoking is bad for our Health, environment and others. It is harmful for every organ of our body. In simple words, smokers are near death stage. Nicotine is the highly addictive drug found in Tobacco. The highly use of this drug stops your body growth and results in causing various diseases.
It is not easy to give it up easily but if you want to stop your any bad habit it can be done. The choice is yours that how you want to quit, what kind of help you need, which option you want to choose and where you want to go.
So, think upon it seriously and live a safe life.

Lung Cancer is known to be associated with smoking and once developed there are over 90% chances that you will die due to the cancer.
Cancer is an abnormal disorganized growth of cells in the tissue of a person. Cancer cells keep on multiplying without paying head to the body's command to stop. This abnormal growth of cells destroys the normal structure and the function of the affected tissue and the body in general. Among other cancers Lungs cancer is one of the most common causes of death.
Lung cancer is the Number one cancer killer in the United States and worldwide. However, it is one of the most preventable of cancers. Individuals can slash their risk of getting lung cancer by not smoking or quitting smoking. Non-small cell lung cancer is the more common of this disease's two main categories. Small cell lung cancer is harder to treat because it generally spreads faster.
Lung cancer is a cancer of the lungs characterized by the presence of malignant tumours. Most commonly it is bronchogenic carcinoma (about 90%). Lung cancer is the most lethal of cancers worldwide, causing up to 3 million deaths annually. Only one in ten patients diagnosed with this disease will survive the next five years. Although lung cancer was previously an illness that affected predominately men, the lung cancer rate for women has been increasing in the last few decades, which has been attributed to the rising ratio of female to male smokers. More women die of lung cancer than any other cancer, including breast cancer, ovarian cancer and uterine cancers combined.
There are two main types of lung cancer categorized by the size and appearance of the malignant cells seen by a histopathologist under a microscope: non-small cell (80%) and small-cell (roughly 20%) lung cancer. This classification although based on simple pathomorphological criteria has very important implications for clinical management and prognosis of the disease.
Current research indicates that the factor with the greatest impact on risk of lung cancer is long-term exposure to inhaled carcinogens. The most common means of such exposure is tobacco smoke.
Smoking, particularly of cigarettes, is by far the main contributor to lung cancer, which at least in theory makes it one of the easiest diseases to prevent. In the United States, smoking is estimated to account for 87% of lung cancer cases (90% in men and 79% in women), and in the UK for 90%. Cigarette smoke contains 19 known carcinogens including radioisotopes from the radon decay sequence, nitrosamine, and benzopyrene. Additionally, nicotine appears to depress the immune response to malignant growths in exposed tissue. The length of time a person continues to smoke as well as the amount smoked increases the person's chances of contracting lung cancer. If a person stops smoking, these chances steadily decrease as damage to the lungs is repaired and contaminant particles are gradually vacated. More recent work has shown that, across the developed world, almost 90% of lung cancer deaths are caused by smoking.
Passive smoking—the inhalation of smoke from another's smoking— is claimed to be a cause of lung cancer in non-smokers. Studies from the USA (1986, 1992, 1997, 2001, 2003), Europe (1998), the UK (1998), and Australia (1997) have consistently shown a significant increase in relative risk among those exposed to passive smoke.
The EPA in 1993 claimed that about 3,000 lung cancer-related deaths a year were caused by passive smoking. However, since this report was based on a study that was alleged to be heavily biased and was ruled by a federal judge to be "unscientific", the EPA report was declared null and void by a federal judge in 1998
Your Life is Precious For You For Your Nation & For Your close one...
Smoking is injurious to health...
Its Me Non-Smoker & Healthy :)
