adults who once smoked have now given


BAD NEWS…
 50
MILLION Americans still
smoke despite information
about cancer, lung disease,
heart disease, allergies and
early death.
Fact
 IF
PEOPLE DID NOT SMOKE IT
WOULD DO MORE TO IMPROVE
HEALTH AND PROLONG LIFE
THAN ANY OTHER SINGLE
ACTION IN THE ENTIRE FIELD
OF PREVENTIVE MEDICINE!
Statistics on young
people and smoking
Every day in the USA 3,000 teens start
to smoke even though all of the
messages from school and health
organizations say DON’T!
 Female teens are smoking at a rate
DOUBLE that of 20 years ago!

Statistics on young people
and smoking…cont.
15% of 12-17 year olds use cigarettes.
 One quarter to the teens who smoke
had their first cigarette by 6th grade; one
half had their 1st cig by eighth grade!

Statistics on young people
and smoking…cont.
One billion packs of cigarettes are sold
to teens less than 18 years of age even
though it is against the law!
 At the current rate, 5 5 million children
now living in the USA will DIE of
smoking related diseases.

Why do TEENS Smoke?






Peer Pressure
Relaxation
Influence of advertising and the media
They feel that they are indestructible
They believe that the bad effects only
happen to older people who have smoked for
several years
They believe they can STOP at any time
Cigarettes
 Each
puff contains 4,000
chemicals; at least 43 of
these are known to cause
cancer.
nicotine





Is the Addictive substance in cigarettes.
People smoke to reduce their craving for
nicotine.
A Stimulant
Speeds up the Central Nervous System
(CNS)
Causes increase in blood pressure and heart
rate.
nicotine and smoking



It takes 5-7 seconds for nicotine to reach the
brain
nicotine is absorbed into the blood stream
through the lining of the mouth and lungs
nicotine causes the blood pressure to rise and
the heart rate to increase up to 20 beats per
minute
nicotine and smoking


nicotine causes a decrease in oxygen supply
to the cells
The rush of stimulations of the brain is
followed by a depression and fatigue-this
leads the smoker to seek more nicotine
tar




Is the flavor-producing agent in cigarettes
It is a thick dark fluid that is produced when
tobacco burns.
Several substances in tar are carcinogens
Penetrates smoker’s airways and lungs
paralyzing or destroying the cilia.
carbon monoxide



Odorless, poisonous gas in cigarette
smoke
Passes through the lungs into the blood
Prevents the red blood cells from
carrying oxygen to the body’s cells
Pipes and Cigars
There is a higher incidence of mouth,
lip, and throat cancer found in cigar and
pipe smokers
 Pipes and cigars generate more tar and
other chemicals than cigarettes
 Inhaling pipe or cigar smoke is more
dangerous that cigarette smoke

“Specialty Cigarettes”
Have a stronger tobacco and have
spices like cloves vanilla added
 The cloves in clove cigarettes
anesthetize the throat and allow for
deeper inhalation

Dangers of Smoking
(ANYTHING!)
EVERYDAY at least 1,000 people DIE
from diseases caused by smoking
 Approx. 400,000 deaths per year are
attributed to smoking

Smoking and the
Respiratory System
 Smoking
is associated with 2
chronic obstructive pulmonary
diseases:
•1. Chronic Bronchitis
•2. Pulmonary Emphysema
Chronic Bronchitis
Occurs when the bronchi are irritated
because the cilia have become useless
due to a build up of tar.
 This situation causes chronic coughing
and excessive mucous secretion of the
bronchial tree.

Pulmonary
Emphysema
Caused by the destruction of the tiny
oxygen absorbing sacs in the lungs.
 This situation makes it very difficult to
BREATH!

Lung Cancer



Lung cancer begins when the bronchi
are irritated by cigarette smoke
Cilia are destroyed and mucous cannot
be expelled-a cough develops
Cancerous cells grow in these
conditions, block the bronchi and move
into the lungs
Lung Cancer




75% of deaths from lung cancer in women are
caused from smoking
Smokers are 10 to 15 times more likely to
develop lung cancer
People who smoke 2 or more packs per day
are 20-25 times more likely to get lung cancer
Male smokers between the ages of 30 and 40
can expect to loose 8 years off their life
Smoking and the
Circulatory System


Nicotine speeds up the pulse making the
heart work harder
Smoking constricts the blood vessels
cutting down on blood flow to the limbs
Smoking and the
Circulatory System



Nicotine contributes to plaque build up in
blood vessels-causing hardening of the
arteries and increasing risk of heart attack
Smoking also damages the heart muscle
itself
Raised blood pressure increases the risk of
stroke
Dangers of Smokeless
Tobacco


Leukoplakia- tobacco irritates sensitive
tissue of the mouth and is responsible
for leukoplakia, which are thickened,
white, leathery spots inside the mouth.
These are areas can develop into cancer
of the mouth.
Dangers of Smokeless
Tobacco


More saliva is produced and some gets into
the digestive and urinary tracts-this introduces
tar and other harmful chemicals
Greater tooth wear because of gum damage
Dangers of Smokeless
Tobacco
 Lip
cancer
 Cancer of the mouth
 Stained teeth
 Bad breath
 Gum disease
 Cancer of the cheek and jawbones
Second Hand Smoke


Passive Smoke-smoke that remains in a closed
enviornment after a smoker is finished
Passive smoke is made up of both mainstream
smoke and sidestream smoke.
Second Hand Smoke



Mainstream Smoke- smoke that is blown off
by a smoker
Sidestream Smoke- smoke from a burning
cigarette.
Sidstream smoke is more dangerous than
mainstream smoke because it has not
passed through a filter!!
FACTS
Second Hand Smoke


A non-smoker breathing in a room containing
passive smoke could have inhaled enough tar
and nicotine in an hour to have smoked a
whole cigarette
Non-smokers may develop the same health
problems as smokers
FACTS
Second Hand Smoke



Passive smoke can worsen or cause heart
disease
Non-smokers living with smokers have a
higher risk of heart disease
Each year, 37,000 non-smokers die from
heart disease due to passive smoke
Kicking the Habit!!!
(Please)



Withdrawal-happens when a person who is
physiologically dependent on a substance
stops using that substance.
During that period a person might feel
nervous, moody, or have difficulty sleeping.
The symptoms of withdrawal do not last a
long time!
