Smoking And Its Consequences Essay, Research Paper
My research paper is on smoking 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. 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 is burned does the tar show
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 worst 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 non-smokers can. The place where that extra air should go is now filled
up with tar. The number on disease caused by death 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 blood stream. 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 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 increase 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, decrease. If you do not
smoke for forty-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 sill 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, some might be a little slow
to stomp on the break 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 causes high blood pressure and
high cholesterol. 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 form 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.
Beside 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. The fifth main cause of death is
chronic obstructive pulmonary diseases. Every year around 80,000 people die from COPD.
Eighty to ninety percent of those deaths were caused by smoking. Smoking effects the heart as
well as the other organs of the body. Smoking is known to increase your chances of heart disease
and heart attacks. Many people have bad hearts but when they smoke it makes their hearts worse.
Most people who smoke have high blood pressure. This is not a coincidence. The smoke you
breathe in from the cigarettes makes the arteries in your heart narrow down. Instead of your
arteries being open to its fullest extent, it because much smaller. This cause high blood pressure.
After someone smokes for a long period of time, doctors believe that whey they stop their blood
pressure will return to normal. Although your blood pressure may remain the same, your heart
works easier which reduces your chance of a heart attack.
Smoking sometimes blocks the arteries of heart which cause atherosclerosis. This disease
happens when the circulation through your heart decreases rapidly. It usually only occurs when
at least one artery is blocked. When you smoke not only does your blood pressure go up but you
may end up blocking your heart arteries in the future. These tow reasons are why many smokers
will experience atherosclerosis sometimes in their life. Another type of heart disease is coronary
artery disease. This happens when your blood vessels become too small. Doctors will prescribe
medications to help these heart diseases but they say that not smoking is the best medicine. Many
people are so addicted to cigarettes though that they may never stop. What many people do not
realize is that smoking does not just give you cancer in your organs. Smoking can give you
cancer in your throat, mouth, nose, and hip as well. Since the cigarettes harmful chemicals travel
through your blood stream you can have cancer anywhere. When doctors take the cancer out of
your organs you do not see the end result. They have to actually dig out the cancer tumor. When
you have cancer in your throat or face, everyone can see the result. Huge gapping holes are
everywhere because the cancer had to be carved out of your skin. After this you are deformed for
the rest o your life. Many times the cancer even comes back. If the cancer should come back in
the same place or near the same place, there is usually nothing that anyone can do. When you
smoke, the cancer can be anywhere. You could have cancer in your mouth and in your hip at the
same time. Since the chemicals in the cigarette travel through you blood stream, every part of
your body gets infected. Some people are lucky. Some people do not die from smoking, but in
most cases the people who smoke do indeed die. Many people know how cigarettes cause cancer
and other problems with your organs. Now new studies show that cigarettes seriously damage
your brain as well. When someone inhales nicotine from a cigarette it takes only ten seconds for
it to reach the brain. It rides through your blood stream and passes through the barrier around the
brain that is supposed to keep things out than can be harmful to the brain. Nicotines signal is
basically the same as one of the brains most important signal chemicals. When the nicotine goes
into the brain it fills up all of this space on the brain that the real chemical needs. 1.5 milligrams
of nicotine takes up this space through just one cigarette. With nicotine in your brain, it can
trigger many other chemicals to release into you body. So instead of these chemicals releasing
naturally when needed, nicotine releases them when you do not need them. One of these
chemicals is adrenaline.
The reason your body craves nicotine is also explained in your brain. After awhile these
nicotine cells kill off many of the chemical so cells that it replaces in your brain. With so few of
the real chemical left the brain needs the nicotine to function properly. The brain needs this
chemical because it is the only thing that can tell the other chemicals in the body when to release
itself into the body. Eventually the real chemical will increase to the necessary amount again but
it takes awhile so while the brain is making more of the real chemical it keeps saying that I need
more which is usually why people continue to smoke. When people go into shock from lack of
nicotine, it is because the brain is saying that it needs more of the chemical that has not had
enough time to fully restore itself. People feel tired and nervous if they do not smoke and fill up
the remaining space that is not yet taken up by the real chemical. They feel tired because there is
not enough nicotine cells to falsely release the adrenaline the body is so used to. This is very
dangerous because your brain ends up relying on nicotine.
Women suffer worse efforts from smoking than men suffer. If a woman is using birth
control pills while smoking, she has a greater risk of developing a cardiovascular disease. If
women smoke more than a pack of cigarettes every day, they have a higher chance of being
unable to conceive a child. For women who can still have children, the number of years that they
could possible conceive is drastically reduced because they smoke. Menopause usually starts a lot
earlier than normal when a woman smokes. When a pregnant women smokes, many dangerous
side effects can happen to her unborn child. A few of the problems that can happen are premature
labor, problems with breathing, and death. These things can even happen when the father smokes
and the wife does not smoke.
At least thirty percent of babies that are born to women who smoked during pregnancy are
very underweight. Their birth weight is always at least seven ounces less than a normal baby
which can cause other problems. The reason the baby is smaller is because it got too much
carbon monoxide and not enough oxygen. Around fourteen percent of pre-mature deliveries are
from women who are smoking while pregnant. Also about ten percent of all miscarriages happen
to women who smoked while pregnant. The chance of having a miscarriage is actually greater
with women who smoke while pregnant. Their chance of having a miscarriage is about twice the
chance of a women who does not smoke while pregnant. The nicotine and carbon monoxide that
the women inhales goes straight to the placenta. This also prevents the fetus from getting all of
the different nutrients and oxygen that it needs to be able to be healthy at birth. The nicotine is
still fed to the baby after he his born. When a mother who smoked through pregnancy, breast
feeds her baby, nicotine is transferred to the baby. All of this can happen even when the woman
herself does not smoke but her husband does.
Some other problems that usually occur are congenital malformation, bleeding in the
womb, rupture of membrane and SIDS. While growing up these children will continue to have
problems. Most of them will have brain function disorders, psychological abnormalities,
hyperactivity, asthma, more colds, bronchitis, and respiratory diseases.
Lately there have been more teenage smokers than ever before. Companies are making
their cigarette ads more noticeable to teenagers which is taking a deadly toll. The reason why
many kids feel the need to smoke is peer pressure. Kids see older kids or their friends smoking so
they smoke too. For teenage girls there is usually a different reason. They want to lose weight or
they want people to think that they are glamorous, like a movie star. Today there are going to be
one thousand adults who die from smoking while they were a teenager. Those one thousand
people wanted to be cool or maybe lose weight so they started smoking. Unfortunately those
thousand people are going to die for it today. The really sad part is that three thousand teenagers
will start smoking today taking the pace of those one thousand adults who died. Not only do you
endanger yourself, other people, and your children but people who smoke cigarettes usually end
up addicted to together drugs like marijuana. No matter what anyone says, smoking is a wrong.
