What's In A Cigarette.

What's in a cigarette
A cigarette is made up of 3 parts.
A light weight paper holds the cigarette together, this can
vary in porosity and is often bleached with chlorine.
The filter is made of cellulose acetate, its purpose is to trap
some of the tar and smoke as it is drawn through, it also serves
to cool the smoke making it easier to inhale.
Up to 600 different additives may be used in any cigarette. When
smoked the combined ingredients release 4,000 chemical
compounds, including ammonia, cyanide, carbon monoxide, cadmium,
formaldehyde, benzene, arsenic, tar and nicotine.
Why is smoking addictive
Nicotine is the addictive ingredient in cigarettes. From
inhalation it's quickly drawn into the blood stream, reaching
the brain in under 10 seconds to create a physiological
reaction. With regular use the body adapts to the increased
stimulation, one way it does this is to grow more receptors in
the brain. However, the effect of a cigarette dissipates in a
matter of minutes, urging the smoker to light up another
cigarette to get the same reward feelings and stave off any
withdrawal symptoms.
What are the immediate effects
Just one cigarette immediately increases blood pressure and
heart rate. The brain and nervous system is stimulated,
paradoxicly making the smoker feel both relaxed yet with
increased concentration, this gives the smoker their 'high'. The
increase of chemicals in the body can cause new smokers to feel
dizzy and sick.
What are the long term effects
If you are a smoker it's worth knowing the staggering negative
effects smoking has on the body.
LUNGS
Hydrogen cyanide and other toxic chemicals damage the lining of
the lungs and bronchial tubes, destroying protective structures
and leaving the lungs open to infection. Smokers tend to have
persistent coughs, as well as being more susceptible to colds
and illness. Smokers are 10 times as likely to get lung cancer
and emphysema as non-smokers.
HEART
The effect of smoking on the heart is devastating. The poisoning
effect of carbon monoxide weakens the heart leading to poor
circulation. The reduced blood flow can result amputation of
fingers and toes, lead to male impotence and more severely,
stokes. The formation of fatty deposits causes a rise in blood
pressure which in turn increases the risk of heart attacks.
ORGANS
Smoking damages the esophagus and generates more stomach acid,
which in turn leads to heartburn and ulcers of the digestive
system. It dramatically increases the risk of cancer throughout
the body.
MOUTH
Tobacco smoke can cause gum disease, tooth decay and bad breath
while teeth become stained and yellow. Mouth cancer is also a
possibility.
APPEARANCE
Smoking prematurely ages skin; gives it a greyish appearance and
prone to more wrinkles. Psoriases, which is a chronic skin
disease is 3 times more likely to develop if you smoke. Hair
becomes weaker, eyes duller and over time fingers become
discoloured.
Passive smoking
Scientific research has shown that non-smokers exposed to
passive smoke face a 25% increase risk in heart disease and lung
cancer, and a 50-60% increased risk of coronary heart disease.
Passive smoking is particularly harmful to children, and could
lead to bronchitis, pneumonia, coughing and wheezing, asthma
attacks, middle ear disease and cot death.
