Tobacco Use
A serious
Health Risk
According to the
Surgeon General,
tobacco use,
particularly
smoking, is the
number 1 cause
of preventable
disease and
death in the
United States
What does
preventable mean?



Smoking is responsible for 1 out of every 5
deaths.
Cigarette smoking kills more Americans than
AIDS, alcohol, car accidents, murders,
suicides, drugs, and fires combined!
Approximately 90% of all smokers start
before age 18; the average age for a new
smoker is 13.

Addictive Drug – a substance that causes
physiological and psychological dependence
Physiological dependence
-physically and chemically needing a
substance
Psychological dependence
-mentally and emotionally needing a
substance, negative coping mechanism

Nicotine-the addictive drug found in tobacco
leaves
◦ All tobacco products contain nicotine
◦ Nicotine contributes to plaque buildup in blood
vessels, increasing your chance of arteriosclerosis.
◦ Stimulant – a drug that increases actions of the
central nervous system, heart, and other organs


Carcinogens – cancer causing substance
Tar – thick, sticky, dark fluid produced when
tobacco burns
◦ Harmful to the lungs because it paralyzes cilia.

Carbon Monoxide – colorless, odorless, and
poisonous gas
◦ When present in the blood, the body’s tissues and cells
are deprived of oxygen!

SMOKE FROM BURNING TOBACCO IS TOXIC AND
SMOKE (AND SECOND HAND SMOKE) IS
CONSIDERED A GROUP A CARCINOGEN, THE
MOST DANGEROUS CARCINOGEN!


Smokeless Tobacco – sniffed through the nose,
held in the mouth, or chewed
Leukoplakia – thick, white, leather spots on the
inside of the mouth then can develop into oral
cancer
◦ The mouth has sensitive tissues that are damaged easily

BECAUSE IT IS HELD IN THE MOUTH FOR A
LENGTH OF TIME, THE AMOUNT OF NICOTINEN
AND CARNINOGENS (28) AT 2-3X’S THE AMOUNT
OF SMOKING TOBACCO
Which chemicals
are you shocked to
learn are in
cigarettes?
Smelly
hair
Bad breath
Increased
Heart Rate
Changes in
Brain Chemistry
Dulled taste

Increased
Respirations
Reduced
appetite
Smelly skin
Smelly

Nervous System
Addiction
Increased risk of Stroke
Outward Appearance
Aging of skin
Wrinkles
Discoloration of skin

Respiratory System
◦ Smoker’s Hack
◦ Emphysema –
destroys tiny air sacs
in the lungs, making
breathing
extremely
difficult.
◦ Lung Cancer
Digestive System
Cancer (mouth,
throat)
Cardiovascular
System
Increased blood
pressure, heart
attack, hardened
arteries
Excretory System
Increased cancer
risk of the bladder,
kidneys

Do you think that
graphic warning labels
on cigarette packages
will discourage
teenagers from
starting to smoke?
What about individuals
who already smoke?
Would these labels
discourage them from
smoking?
Quick Write

1. Legal Consequence
◦ Tobacco use is illegal for anyone under the age of
18 in all states, 19 in the State of Utah, Alaska, and
Alabama

Illegal to smoke inside in any establishment
in what states?
◦ Cannot smoke within 25 ft of any air intake or
door/window
◦ Have to smoke out in the cold
◦ Against the law to smoke in a car with a child

2. Social Consequences
◦ Many find the smell of smoke offensive
◦ Smoke Breaks
◦ Housing

3. Financial Consequence
◦ Someone who smokes a pack of
cigarettes a day will spend more than
$2,000/yr. Tax payers pay more than
$97 Billion/Yr. in medical costs for
tobacco users


What could you buy with
$2,000.00?
97,000,000/Taxpayers = ?



1. Choose friends that
don’t use tobacco
2. Avoid situations where
tobacco may be used
3. Practice refusal skills
◦ Your refusal skill may be
simple
 “No thanks”
◦ Your refusal skill may need
a reason
 “No, I can’t. I need to stay
fit and ready for my track
meet.”


Within 20 min – blood pressure and pulse rates drop. Body
temp in limbs return to normal
Within 8 hrs – oxygen levels return to normal
In 24 hrs – chance of heart attack decreases
In 48 hrs – nerve endings begin to re-grow. Sense of taste
and smell improves
In 3 days – breathing becomes easier as lung capacity
increases
In 2 weeks to 3 months – lungs function up to 30% better
In 1 to 9 months – lung cilia re-grow, and coughing, sinus
congestion, and shortness of breath decrease
In 1 year – coronary heart disease risk is cut in half
In 5 years – risk of cancers (lung, mouth, throat,
esophagus) is reduced by 50%
In 10 years – risk of cancers (bladder, kidney, cervix,
pancreas) decreases


Nicotine Withdrawal – cravings and
discomforts caused by the absence of the
nicotine
Nicotine Substitute – products that deliver
small amounts of nicotine into the users
system to help them give up the tobacco
habit
◦ Examples?
It is important to avoid social triggers!

Environmental Tobacco Smoke (ETS) – air that
has been contaminated by tobacco smoke

Smoke exhaled from
the lungs of a smoker

Smoke from the
burning end of a
cigarette, pipe, or cigar
◦ More dangerous than
mainstream smoke because it
has higher concentrations of
carcinogens, nicotine, and tar.
