1. Overview

Smoking is responsible for the occurrence of many chronic diseases, cancer, cardiovascular disorders, chronic obstructive disease and, the most important, premature death. Hundreds of thousands of people lose their lives each year due to smoking.

Smoking is one of the preventable leading causes of death around the world. Recent studies have confirmed that smokers can undermine the health of non-smokers in some environments.

2. Smoking triggers cancer

Over 90% of patients suffering from lung cancer developed the disease due to smoking. The presence of this type of carcinoma is one of the most common causes of cancer deaths around the world.

Smokers have an increased risk of developing:
- Bladder cancer;
- Kidney cancer;
- Cancer of the pharynx and larynx;
- Oral cancer;
- Cancer of the esophagus;
- Pancreatic cancer;
- Stomach cancer;
- Some types of leukemia;
- Cancer of the nose and sinuses;
- Cervical cancer;
- Bowel cancer;
- Ovarian cancer;
- Breast cancer.

Also, smoking increases the possibility of cancer recurrence!

3. Smoking increases risk of cancer

Scientists say there are over 4,000 compounds in cigarettes used by smokers. A significant number of them are toxic and destroy body cells, while others are carcinogenic.

The most known chemicals that tobacco smoke contains are:

- Nicotine, which do not determine cancer, but addictive. Smokers find it difficult to quit smoking because they are addicted to nicotine. Nicotine is an extremely fast-acting drug. It reaches the brain within 15 seconds after it is inhaled.

If cigarettes and other tobacco products would not contain nicotine, the number of people who smoke would drop drastically every day. Without nicotine, the tobacco industry would collapse. Nicotine is used in a controlled manner, including as an insecticide.

Exposure to large amounts of nicotine triggers symptoms as vomiting, convulsions, central nervous system depression and growth retardation. This can affect including normal development of a fetus.

- Carbon monoxide is a poisoning gas that does not taste or smell. Is difficult for the body to differentiate carbon monoxide of oxygen and absorbs it into blood. Heating systems that do not work correctly emit dangerous carbon monoxide, as well as tailpipes of cars.

If a person inspires a large amount of carbon monoxide can enter a coma and die. Carbon monoxide depreciates the cardiac and muscle function, causing fatigue, weakness and dizziness. It is especially toxic to babies who still develop in the womb, for infants and for people with heart or lung disease.

- Tar is composed of several cancer-causing chemicals. When a smoker inhales cigarette smoke, 70% of the tar remains in the lungs. Smoking causes fat deposits on the arteries, a phenomenon known as atherosclerosis, the leading cause of smokers’ deaths. Smoking is a significant factor predisposing to the development of risk for coronary heart disease.

People with coronary heart disease have a much better chance to show a heart attack. When cigarette smoke is combined with other risk factors such as hypertension, obesity, physical inactivity and diabetes, can develop serious chronic illness, while death rate is very high.

Smoking aggravates cardiovascular disease, raises blood pressure, makes it difficult to exercise and contribute to the formation of blood clots easily. In people who have undergone bypass surgery and smokes the probability for the disease to come back is very high.

Experts believe that smoking is one of the most important risk factors for young people, whether they are male or female. A female person who smokes and use oral contraceptives may develop coronary heart disease and stroke compared with women using oral contraceptives but do not smoke.

Also to those who smoke, will decrease good cholesterol, and if there is a family medical history including cardiovascular disease, the risk of developing such diseases is very high. A much higher percentage of smokers compared with people who do not smoke and have the same age, suffer strokes.

The cerebral vascular system is affected when a person inhales tobacco constantly. Those who smoke are more likely to manifest arterial disease.

4. Cigarette smoke contains harmful chemicals for the body

Except tar, nicotine and carbon monoxide whose effects have already been presented, cigarette smoke also contain:

- Acetaldehyde – a chemical component used in resins and adhesives, considered to be a carcinogen. Experts say that acetaldehyde facilitates the absorption of dangerous chemicals in bronchial pathways.

- Acetone – is a chemical used in the composition of solvents that can irritate eyes, nose and throat. Long-term exposure may damage the liver and kidneys.

- Benzene – is a constitutive element of gasoline and causes several types of cancer, including leukemia.

- Chromium – used to treat wood, for preservatives for wood, metal and alloy surfaces. It contribute to lung cancer! Beside this, people working in the weld are at greatest risk of exposure.

- Cresol – Found in disinfectant’s composition, wood preservatives and solvents. Acute inhalation may cause irritation of the throat, nose and upper respiratory tract.

- Isoprene – is similar to the 1.3-butadiene, being used to make rubber. It causes irritation to skin, eyes and mucous membranes.

- Lead – is used to manufacture metal alloys and paints. It may affect the reproductive system, central nervous system and kidneys. It may lead to the development of stomach problems and anemia installation, being also carcinogen and particularly toxic for children.

- Nickel – is a known carcinogen that causes asthma and upper respiratory tract irritation.
