Introduction

Smoking is a kind of self destruction. It is very

addictive and dangerous for health. In this

project we will tray to understand and explain

the course to that addiction.

We chose this topic, smoking because we

know that smoking isn't healthy and people

should quit smoking. We want to learn more

about smoking and the problems it causes to

the human body.

We have found the material for the project

mostly in the Internet.

What is smoking Addiction?

Smoking addiction means a person who has

formed an uncontrollable dependence on

cigarettes to the point where stopping smoking

would cause severe emotional, mental, or

physical reactions.

Everyone knows that smoking is harmful and

addictive, but few people realize just how risky

and addictive it is.

Chances are that about one out of three

smokers, who do not stop, will eventually die

because of their smoking. Some will die in

their 40's, others will die later. On average,

they will die 10 to 15 years earlier than they

would have died from other causes.

Most smokers want to stop and do indeed try,

but only one in three succeeds in stopping

permanently before the age of 60. By this time,

much harm may have been done to the body -

some of it irreversible.

Those who eventually quit smoking usually

try to stop two or three times before

they're successful.

Only 2.5 percent of smokers successfully

quit each year.

The reason why so many people fail to stop is

because they are addicted. Being addicted

does not mean that you cannot stop - only that

it is likely to be difficult. Anyone can succeed if

he or she goes about it in the right way.

How you stop - and, especially, when you stop

- is a very personal matter. Only you know

what you have to give up, and how the

benefits of smoking can be weighed against

the benefits of stopping. Harassment and

pressure from others who do not understand is

often unhelpful. You will only stop when you

have made a firm decision. When you do

make up your mind, however, you can

succeed, regardless of how addicted you may

be.

If you stop smoking before or during middle

age (age 35 to 50), you will avoid about 90

percent of the lung cancer risk. If you are

currently middle-aged, you are also more likely

to succeed in quitting now than when you were

younger.

Why Is Smoking Addictive?

Nicotine is the drug in tobacco that causes

addiction. It is absorbed and enters the

bloodstream, through the lungs when smoke is

inhaled, and through the lining of the mouth

(buccal mucosa) when tobacco is chewed or

used as oral snuff or for non-inhaled pipe and

cigar smoking. It is also absorbed through the

nose from nasal snuff, which was popular in

the 18th century.

Nicotine is a psychoactive drug with stimulant

effects on the electrical activity of the brain. It

also has calming effects, especially at times of

stress, as well as effects on hormonal and

other systems throughout the body. Although

its subjective effects are less dramatic and

obvious than those of some other addictive

drugs, smoking doses of nicotine causes

activation of "pleasure centers" in the brain (for

example, the mesolimbic dopamine system),

which may explain the pleasure, and

addictiveness of smoking.

Smokers develop tolerance to nicotine and

can take higher doses without feeling sick than

when they first started smoking. Many of the

unpleasant effects of cigarette withdrawal are

due to lack of nicotine and are reversed or

alleviated by nicotine replacement (for

example, nicotine chewing gum or the nicotine

patch).

As with other addictions, it is difficult to give up

smoking, and without help most smokers fail

despite trying many times. Even after stopping

successfully for a while, most relapse within 2

to 3 months. More alarming perhaps than the

strength of the addiction is the ease with which

it develops. Although teenagers often start

smoking for psychosocial reasons, the effects

of nicotine soon gain control.

Studies show that tobacco use usually begins

in early adolescence and those who begin

smoking at an early age are more likely to

develop severe nicotine addiction than those

who start later. Each day, more than 4,800

adolescents smoke their first cigarette, and 42

percent of them go on to become regular

smokers

Is Smoking Physical Addiction?

Smoking is a physical addiction that produces

a "chain reaction" in the body:

Nicotine acts on receptors normally used

by one of the main neurotransmitters in

the brain and nervous system

(acetylcholine). Neurotransmitters are the

"chemical messengers" released by nerve

cells to communicate with other cells by

altering their electrical activity.

The body responds to nicotine at these

receptors as if it was the natural

transmitter (acetylcholine) and the activity

and physiological functions of many brain

systems are altered.

With repeated nicotine dosage the body

adapts to what it regards as extra

acetylcholine in an attempt to restore

normal function. One way it does this is to

grow more acetylcholine receptors.

Thus nicotine induces structural as well as

functional changes in the brain of smokers.

When nicotine is suddenly withdrawn,

physiological functions in the brain and other

parts of the body are disturbed. This is known as

withdrawal syndrome. It takes time for the body to

readjust to functioning normally without nicotine.

Shovel's Reflection

I enjoyed doing the project with my friends.

I specially enjoyed the part of reading about

smoking addiction. Now, I know how you

become cigarette addict.

I wanted to do the project about this subject

because I don’t like smokers. I wanted to know

more about the problems that it caused to our,

body and I think every one that smokes is

stupid because he hurts his body.

When I did the project I learned some new things

that I hadn’t known before.

Now after doing the project, I am 100% sure that I

don’t want to be a smoker, and I don’t want that any

one from my family will get hurt by cigarettes.

Daniel's Reflection

The project about smoking thought me a lot

like about the reasons why people start to

smoking or what the reasons that people are

addicted to smoke.

The most important thing that I have learned is

that smoking is bringing us closer to death

which is why everybody should stop smoking.

I enjoyed working with my friends, but I didn’t

like to argue with Shovel about the design of

the cover.

Yotam's Reflection

Working on this subject was actually interesting but did not add any new information to my knowledge.It was still nice to share my knowledge with my friends.

I learned that smoking is not healthy. Unfortunately, I have experienced a lot of passive smoking at home but all my family has stopped.

Tomer's Reflection

I choose writing about cigarette addiction for a few reasons:First, I wanted to learn more about this subject and to enrich my knowledge about the effects of smoking.Second, my father is a heavy smoker and I don’t like it at all.

After doing this project I realized what smoking is, and who it being addicted.

I enjoyed working with my classmates, when everybody contributed his knowledge about the subject.

Smoking is a very serious issue, and we should made people more aware of the effects and consequences of smoking.
