Smoking=HARMFUL and DEATH!!!!

Nowadays, when i walk along the street, i saw many people are smoking in everywhere. Not only the olders are smoking, even teenager and children are smoking too. I also saw women smoke. It is so terrible. The amount of people smoke is increasing due the stressfulness in life such as working very hard to earn money; they are also influenced by commercial and friends.



Generally, smoking is the second major cause of death in the world. Smoking causes lung cancer and others dangerous disease. Cigarettes and other forms of tobacco consist of dried tobacco leaves, and other ingredients added for flavor and other properties. Cigarette smoking is known as the act of inhaling and exhaling the fumes of burning tobacco in cigars, cigarettes or pipes.


Why smoking cause cancer and others harmful???why??



Smoking is dangerous because of the tobacco and tobacco smoke. MORE THAN 60 carcinogenic compounds are found in them. The tobacco smoke includes carbon monoxide, hydrogen cyanide, ammonia and other highly toxic irritants. Therefore, we can imagine that when we smoke, all of these substances will move inside to our body and stay within. SCARRY! Smoking also make us addict to it. Therefore, it is very hard for the smokers to quit smoking.


There are many harmful chemicals within the cigarettes..



Major Harmful Chemicals







Such as the nicotine..people are addicted to smoke due to this chemical..Nicotine is an alkaloid. An alkaloid is composed of carbon, hydrogen, nitrogen and oxygen(only present sometimes). This chemical is very toxic within our body. Nicotine is absorbed through the skin and mucosal lining of the mouth and nose and also inhalation by lungs. It increases the level of the dopamine(responsible for feelings of pleasure) when it passes into the brain. The acute effects of nicotine subside within minutes



Besides that, the tobacco smoke is very dangerous for smokers because it causes cell mutation. Carbon monoxide presents in the tobacco smoke. Normally, carbon dioxide gas is similar with the gas found in car's exhaust system. It is a colorless and odorless gas. Oxygen will bind with hemogloblin (oxyhemogloblin)and attach to our red blood cells. However, carbon monoxide will compete with oxygen to bind with hemogloblin. This action will deactivate red blood cells. The increased levels of carbon monoxide may cause less oxygen flow into brain. Luckily, our body is able to eliminate most of the carbon monoxide very quickly within a few days of quitting smoking.




In addition, Tar is also a harmful chemical. It is a dark substance that delivers nicotine to the lungs. When tobacco smoke is inhaled, most of the tar is retained for a while in the mucous lining of the lungs and then mostly distributed throughout the body. More of the carcinogens in the smoke are dissolved into the bloodstream as a person drinks beverage which contains alcohol. It is because alcohol is a very effective solvent. Alcohol increases the harmfulness of the tar into our body.



The OTHERS chemicals in cigarettes and tobacco smokes:


a)Benzene-petrol additive


It is a colourless hydrocarbon which obtained from coal and petroleum.It is a very volatile chemical. It is flammable and gives a sweet odour. It is used as a solvent in fuel and in chemical manufacture. It is a known carcinogen and is associated with leukaemia.


b)Formaldehyde-embalming fluid


Colourless liquid and highly poisonous. It is flammable with a strong odor. Most formaldehyde is released into our environment by the burning of fuels and household waste. However, cigarette smoke contains formaldehyde.It functions to preserve dead bodies. It causes cancer, respiratory, skin and gastrointestinal problems.


c)Ammonia (toilet cleaner)



Act as a flavouring. It will free nicotine from tobacco and turns it into a gas which found in dry cleaning fluids. Higher concentration of ammonia causes the tightness of the chest, pulmonary edema, cyanosis, and a rapid, weak pulse. The ammonia may irritate our eyes and upper respiratory tract, and also the inflammation of the mucous membrane.

d)Acetone (nail polish remover)

fragrant volatile liquid ketone. It is used as a solvent. For example, nail polish remover.


e)Hydrogen cyanide-colourless and poisonous


It has a bitter almond smell. Cyanide is a fast-acting and potentially deadly chemical. It prevents the body cells from using oxygen properly. The cells will die without oxygen. Cyanide is released from natural substances found in some foods(apple seeds and peach pits) and certain plants too. Cyanide is used to make paper, textiles and plastics. It is in the chemicals used to develop photographs. It acts as a pesticide too.


f)Arsenic-very poisonous


Arsenic burns our lips and causes bad breath. Arsenic is taken up by tobacco leaves from the soil. Two forms of arsenic compounds: organic and inorganic. Organic arsenic is formed when arsenic combines with carbon and hydrogen. Inorganic arsenic is formed when arsenic combines with elements such as oxygen, chlorine and sulfur. Organic arsenic is less toxic than inorganic arsenic; inorganic arsenic causes cancer.


There are so many harmful chemicals within the cigarettes. Why should we risk our life?





Stop smoking!! Thinks about the people who concerns and cares us..
