Smoking can cause irreparable damage to your mind and body. Chemicals in the tobacco travel to all parts of the body, leaving no area unaffected. According to available data, smoking causes 30% of all cancer deaths and about 80% deaths from emphysema and bronchitis. In addition to adversely affecting yourself, smoking also has a severe impact on your near and dear ones. According to WHO, about 600,000 people die every year from passive smoking. Out of the deaths that occur due to this, 1/3rd is that of children.

The Indian situation
While 85% of tobacco users worldwide consume it in the form of cigarettes, in India only 13% use it in that form. Additionally, 54% use it in the form of beedis. A study conducted on Indian smokers has revealed that an average of 8.2 cigarettes is smoked by an individual daily.

The study also revealed that the number of cigarettes smoked every year had grown to over 6 trillion. While 1 out of 10 adults dies from tobacco use worldwide, 5% of deaths in women and 20% of deaths in men in India are caused by cigarette and beedi smoking.

What happens when you smoke?
Cigarette smoke is made up of 4000 chemicals that are present either as tiny particles or gases and about 50 are known to lead to cancer, the toxin nicotine being one of them. In addition to nicotine, the chemicals that make up cigarette smoke also include tar and carbon monoxide. Prolonged exposure to these toxins can hamper your body's ability to filter air and clean the lungs. The smoke not only irritates the lungs but also causes excess production of mucus.

It also causes a paralysis of the tiny hair-like structures like cilia that line the airways and are responsible for removing dust and dirt from the organ. Paralysis of these hair-like structures also causes a buildup of mucus and toxic substances, leading to lung congestion. The extra mucus that is produced causes smokers to suffer from the very ubiquitous smoker's cough and chronic bronchitis.

It's also one of the many triggers of asthma, which brings about the narrowing and inflammation of the airways. Long-term exposure to tobacco smoke causes the destruction of the structure of the lung, walls of the airways as well as lung tissue. The result is a condition known as emphysema. Additionally, smoking also leads to cancer of the lung and over 80% lung cancer cases occur due to this habit. If you wish to discuss about any specific problem, you can consult a Pulmonologist.
