Tobacco use is one of the leading causes of death worldwide, but it is also the largest preventable cause of death. Read the article to know how smoking tobacco can affect various parts of your body.

Smoking - a Preventable Cause of Death

Tobacco, taken in any form, can lead to many diseases, including cancers. According to the data from the Global Adult Tobacco Survey, in low and middle-income countries (including India), 41 % of men and 5 % of women smoke. But the most important concern is the rising trend of smoking in developing countries like India.

Tobacco is used in the form of smoking, chewing, sniffing, and dipping. Among them, smoking is the most prevalent form. There are many diseases caused by smoking like peripheral arterial disease, stroke, heart diseases, and lung diseases like COPD, but the most dreaded and frightening disease is cancer. There are many cancers in various sites or organs in the body, but the most definitive evidence for smoking-associated cancer is in the following sites:

1. Lung.

2. Bladder.

3. Cervix.

4. Colon and rectum.

5. Esophagus.

6. Kidney.

7. Larynx.

8. Liver.

9. Oral cavity.

10. Pancreas.

11. Stomach.

Effects of Smoking on the Body:

Some of the side effects of smoking are:

Nicotine Effects:

Nicotine is the major addictive substance and primary reinforcer of continued smoking, and there are 72 measurable carcinogens in smoking. People who have smoked more than 100 cigarettes in their lifetime are particularly at risk for developing cancer. According to the WHO (World Health Organization), after quitting smoking for ten years, the risk of lung cancer reduces to about half that of a smoker.

Nicotine Replacement Therapy:

As nicotine is the major addictive substance and it is not a carcinogen, pharmacotherapy agents for nicotine replacement are available in various forms like:

1. Transdermal patches (to be applied over the skin).

2. Chewing gum.

3. Lozenge.

4. Nasal spray.

5. Inhaler.

6. Tablet Bupropion.

7. Tablet Vereniciline.

The last two should be taken only on the advice of a medical professional. So, consult a physician for smoking cessation before it is too late.
