Smoking Essay, Research Paper

My research paper is on smoking diseases and other consequences of smoking. Many times when people think of smoking diseases they think of heart disease and lung cancer. While those things are very true there are subtle things that happen also. Most of the time after someone has smoked their third cigarette they are hooked. Nicotine is one of the most addictive substances on earth. Usually once people start smoking they never stop.

Tobacco was found in the sixteenth century. Many Indian tribes were addicted to tobacco. When people came to America they became hooked on tobacco as well. Many sailors killed these Indians in order to get more of this addictive substance.

The three most harmful substances in a cigarette is tar, nicotine, and carbon monoxide.

Tar is a very interesting chemical. When a cigarette remains unburned tar is not there. Only when the cigarette begins to burn does tar shows up as a chemical. While filters on the cigarette keep out a little bit of the tar, it is still very dangerous. The tar in the cigarette is actually the same as road tar.

Tar causes numerous types of cancer all over your body. One of the worse things that tar does is it fills up your lungs. The tar goes directly into your lungs and stays there forever. This is the reason why smokers can not inhale as much oxygen as nonsmokers can. The place where that extra air should go is now filled up with tar. Tar’s number one disease that it causes is emphysema.

Nicotine is the reason why people are addicted to cigarettes. Nicotine kills nerve endings and mucosae. Mucosae is the thin layer of skin in your nose and mouth that are full of blood cells. Nicotine goes straight to the brain. When the nicotine goes into the bloodstream it travels all over the body. That is why you can get cancer from smoking anywhere in your body. Nicotine is actually the least harmful out of all the chemicals in a cigarette Since people crave the nicotine though they ingest all of these other life-killing chemicals.

Carbon monoxide is a chemical in a gas form. Like tar it only appears when the cigarette is burned. Unlike nicotine, carbon monoxide does not go to the brain. Instead it goes to the lungs and straight into the bloodstream. When the carbon monoxide enters the lungs the body is deprived of the oxygen it needs.

One out of every six deaths are caused by smoking. In 1985 alone more than 400,000 people died from smoking. They died just because they wanted a dangerous substance in their body.

Many people believe that you have to be smoke free for a very long period of time for it to make any real difference. That is not true. Even if you do not smoke for twenty minutes it greatly benefits you.

When you do not smoke for twenty minutes your blood pressure goes back to normal, your pulse rate drops to normal, and your temperature increases back to normal. When you stop smoking for eight hours the carbon monoxide in your blood drops down to the normal amount and more oxygen goes into your blood. When you do not smoke for twenty-four hours the chance of having a heart attack or other serious heart problems, due to smoking, decreases.

If you do not smoke for fourty-eight hours the nerve endings, that were killed, start to regrow themselves; your ability to smell things and taste food is increased; also your ability to walk in a straight line becomes easier. When you stop smoking for two weeks to three months your blood circulation improves and your lungs functioning ability increases by 30%.

If you do not smoke from one to nine months your coughing, sinus infection, and shortness of breath decrease; your cilia in your lungs start to regrow which lets the body handle mucus better, it cleans the lungs, and reduces lung infections. When someone does not smoke for one year the risk of serious heart disease is half that of someone who still smokes.

The top five causes of death are heart disease, cancer, strokes, accidents, and chronic obstructive pulmonary diseases(mostly bronchitis and emphysema). Every single one of those reasons is usually caused by smoking. Even smoking causes a few accidents. When you smoke your reaction skills do not function as well as they should. Therefore, someone might be a little slow to stomp on the brake and have an accident.

There are about three reasons why heart disease occurs. Smoking, high blood pressure, and high cholesterol levels are those three reasons. Not only is smoking the top cause of heart disease but smoking also cause high blood pressure and high cholesterol. Not just smoking causes high blood pressure and high cholesterol though. In the year of 1986, 765,000 people died from heart disease. More than 40% of those deaths would not have happened if people did not smoke.

Cancer is the second main cause of death. Over a half a million people die from cancer every year. 30% of that half a million deaths are from smoking and over 90% of deaths from lung cancer was caused by smoking. Besides lung cancer here are the most common cancers caused by smoking: bladder cancer, pancreas cancer, kidney cancer, larynx cancer, mouth cancer, esophagus cancer, and uterine cervix cancer.

The third main cause of death is strokes. Every year more than 150,000 people die from strokes. The main cause of strokes is again smoking.
