The Harmful effects of
smoking

How do all those chemicals get
in a cigarette?
~Farmers use many chemicals to grow tobacco. They
use fertilizers to make the soil rich and insecticides to
kill the insects that eat the tobacco plant.
~After the tobacco plants are picked, they are dried,
and machines break up the leaves into small pieces.
Artificial flavorings and other chemicals are added.
Some chemicals are put in cigarettes to keep them
burning; otherwise, they would go out.

Brain
Nicotine stimulates the “pleasure centers”
in the brain than acts as a tranquilizer and
sedative
Nicotine directly affects, alters, and takes
control of specialized receptor cells in the
brain responsible for regulating well-being,
mood, and memory
The drug remains active for 20-40
minutes, than withdrawal symptoms begin
Mood changes: person becomes irritable,
anxious, and discomfort becomes more
severe leading to addiction
Throat
Cancer of Larynx (voice box) and
esophagus
Irritates membranes of the throat
Heart
Nicotine raises heart rate
Increases blood pressure
Constricts blood vessels
Carbon monoxide decreases delivery of
oxygen to the heart, increasing risk of
heart attack and strokes
Causes weakening of heart muscle’s ability
to pump blood, leading to death
Causes aortic aneurysms and pulmonary
heart disease
Liver
Causes cirrhosis of the liver
Adrenal Glands
Stimulates adrenaline production,
speeding up the heart and increasing
blood pressure
Vertebrae
Increased risk of vertebral cancer
Reproductive System
Male: reduces sex drive and increases risk
of impotence in males
Females: increased chance of cervical
cancer, less fertile, and brings on
menopause earlier
Increases chance of miscarriage,
pregnancy complications, bleeding, and
premature delivery
May cause impairment of baby’s growth,
intellect and emotional development
Mouth
Dulls taste buds
Irritates membranes of mouth
Bleeding and receding gums
Gum Disease
Foul breath
Hair growth on tongue
Numbness
Staining teeth, tooth decay, loss of teeth
Cancer of mouth
LUNGS
Chronic obstructive lung disease
Damages and destroys tiny air sacs reducing
lungs ability to bring in oxygen and remove
carbon dioxide
Emphysema: damaged air sacs
Bronchial tubes become inflammed, and
thickened with mucus narrowing air
passages=chronic bronchitis
Lung cancer: tar and other particles settle in
bronchiole tubes causing cancer
Healthy Lung
Lung with Cancer
(caused from smoking)

Stomach and Duodenum
Stomach and duodenal ulcers
develop, creating burning pain
Kidneys
Reduces kidneys ability to process
fluids and waste
Inhibits formation of urine
Cancer
Bladder
Causes cancer of the bladder
Bones
Increased risk of early onset of
osteoporosis (weakening, softening
and thinning of the bone
Secondhand Smoke Facts
Comes from two places: smoke exhaled by the
person who smokes and smoke from the end of a
burning cigarette
Contains over 4000 chemicals, 200 are poison
and 43 cause cancer
Secondhand smoke causes cancer at typical
everyday exposure levels
Non-smoking women who live with a spouse who
smokes has a 30% greater risk of lung cancer
Contains cancer-causing and other toxic substances that
are often in greater concentrations than in the smoke
inhaled by the smoker. Some chemical compounds found in
smoke only become carcinogenic after they've come into
contact with certain enzymes found in many of the tissues
of the human body, so the smoke that is breathed out may
be worse than the smoke breathed in by the smoker
through the cigarette.
Secondhand Smoke Contains….
2 times as much tar and nicotine
5 times as much carbon monoxide
50 times as much ammonia as mainstream
It is estimated that only 15% of cigarette smoke
gets inhaled by the smoker. The remaining 85%
lingers in the air for everyone to breathe.
The chemicals found in secondhand smoke are
the same as those inhaled by the active
smoker. However, because their combustion is
incomplete, the concentration is 100
times higher.

How does secondhand smoke
affect you?
2 hours in an enclosed smoky area is
equivalent to smoking 4 cigarettes
2 hours in a non-smoking area of a
building where smoking is taking
place is equal to smoking 2
cigarettes
When Smokers Quit
20 Minutes After That Last
Cigarette
Blood pressure drops to normal
Pulse rate drops to normal
Body temperature of hands and feet
increases to normal
8 Hours After
Carbon monoxide level in blood
drops to normal
Oxygen level in blood increases to
normal
24 Hours After
Chance of heart attack decreases
48 Hours After
Nerve endings start growing
Ability to smell and taste is enhanced
2 Weeks to 3 months After
Circulation Improves
Walking becomes easier
Lung function increases up to 30%
1 To 9 Months After
Decrease in coughing, sinus
congestion, fatigue, shortness of
breath
One Year Later
Excess risk of coronary heart disease
is half that of a smoker
5 Years After
Lung cancer death rate for average
former smoker (one pack a day)
decreases by almost half
Stroke risk is reduced to that of a
nonsmoker 5-15 years after quitting
Risk of cancer of the mouth, throat
and esophagus is half that of a
smoker’s
10 Years After
Lung cancer death rate similar to
that of non-smokers
Precancerous cells are replaced
Risk of cancer of the mouth, throat,
esophagus, bladder, kidney and
pancreas decreases
15 Years After
Risk of coronary heart disease is that
of a non-smoker
