Chapter 21 Warm-Up
Figure out the cost of smoking 2
packs of cigarettes a day for 18
years. (1 pack is roughly $5)
2 Packs a day is an average for a
Habitual Smoker.
Cost of Smoking
2 packs a day at $5 a pack = $10 a day
 $3,650 a year
 $65,700 over the course of 18 years…
Sounds to me like a pretty good college
education.
 This is (again) just an average. Most “hard
core” smokers smoke more than that.
 Not to mention the costs of medical care
later.

My Grandpa
Smoked from 12 years of age, until he
died at 69. Let’s do the math…
 57 years of smoking 3 packs a day
(average)
 That comes to a WHOPPING $312,075.
 Granted cigarettes did not cost $5 a pack
in the late 1930’s but it was probably
pretty close to that in 1930’s dollar.

My Grandpa
He died when I was 15 after having
countless strokes and heart attacks. Right
before he died, he had to have Quadruple
Bypass Surgery (The worst kind of heart
surgery), and laid in his death bed
wanting another cigarette.
 Tell ME Nicotine is not that addicting!!!!

Chapter 21 Lesson 1

Tobacco Use
 The
number one cause of preventable disease
and death in the United States.
 The government requires all tobacco products
to have warning labels.
 Tobacco contains many health risks.
 It
contains an addictive drug called nicotine.
 Nicotine is a stimulant, raising blood pressure,
increasing heart rate, and contributing to heart
disease and stroke.
Harmful Effects of Cigarette Smoke
Cigarette smoke is a carcinogen – cancercausing substance.
 Cigarette smoke contains tar.

 Tar
is a thick, dark fluid produced when
tobacco burns.
 It damages the lungs’ air sacs and destroys
lung tissue.
 Smokers’ lungs are more susceptible to
bronchitis, pneumonia, and cancer.
continued

Cigarette smoke contains carbon
monoxide.
 Colorless,
odorless, and poisonous gas.
 Replaces oxygen in the blood, depriving
tissues and cells of oxygen.
 Can cause high blood pressure, heart disease,
and hardening of the arteries.
Other Tobacco Sources

Pipes and Cigars
 Cigars
contain more nicotine and produce
more tar and carbon monoxide than
cigarettes do.
 Pipe and cigar tobacco can cause lip, mouth,
and throat cancer.
continued

Smokeless Tobacco (Dip, Chewing
Tobacco)
 Contains
nicotine and carcinogens.
 Body receives two to three times more
nicotine and carcinogens than it receives from
a single cigarette.
 It is addictive and poses a dangerous health
risk.
 Cause
leukoplakia; can cause cancer of throat,
larynx, esophagus, stomach, and pancreas.
How Tobacco Affects the Body

Short-Term effects occur immediately after
using tobacco.
 Changes
in brain chemistry – withdrawal
symptoms – headaches, nervousness,
trembling.
 Increase in respiration and heart rate.
Breathing during physical activity becomes
more difficult.
 Tobacco dulls taste buds and reduces
appetite.
continued
 Causes
bad breath and smelly hair, clothes,
and skin.

Long-Term effects harm many body
systems.
 Harms
the nervous system – damaging cilia
and causing bronchitis.
 Harms respiratory system – destroying the
lungs tiny air sacs, causing emphysema and
possibly cancer.
continued
 Harms
cardiovascular system – restricting
blood vessels and cutting down on circulation.
This leads to arteriosclerosis (hardening of
arteries), coronary heart disease and stroke.

Tobacco bring serious consequences for
teens.
 Legal
consequences for buying cigarettes
underage.
 Smell is offensive, could harm your social life.
 Not to mention the expense of it.
Chapter 21 Warm Up #2
What are some ways that you
have seen used to reduce teen
usage of tobacco?
Reduced Tobacco Use Among Teens
Antismoking campaigns led to restricted tobacco
advertising. Tobacco companies are required to
fund antismoking promotions for young people.
 The cost of tobacco is very expensive.
 Legislative acts limit smoking in public places, so
teens are growing up in an environment that is
less tolerant of secondhand smoke.
 Teens avoid using tobacco because their parents
disapprove of its use.

Strategies for Preventing Tobacco
Use

Strategies can help your decision to live a
tobacco-free lifestyle.
 Choose
friends who share your values and
beliefs, and who don’t use tobacco.
 Avoid situations where tobacco products may
be used.
 Practice in advance how to refuse someone’s
offer to use tobacco. Simply say, “No, thanks,”
or give a simple reason why not.
Reasons to Give Up Tobacco Use






Health problems begin, such as asthma or
respiratory infections.
Users have the desire and commitment to stop.
Users realize how expensive the habit is.
Users understand they can be led into other
risky behaviors.
Users under 18 find it difficult to purchase
tobacco.
Users realize the health risks of secondhand
smoke to family and friends.
Stopping the Addiction Cycle
Overcoming nicotine addiction can be difficult
but not impossible.
 Most users will experience the temporary
symptoms of nicotine withdrawal.




Users may become irritable and have difficulty
concentrating.
Users may experience anxiety and sleep disturbances.
Nicotine substitutes can be used to relieve
withdrawal symptoms.

Sprays, patches, gum and inhalers are available.
Getting Help – Tips for Quitting
Set a target day for quitting.
 Get support from friends and family.
 Identify available local health-related
services.
 Replace tobacco use with healthier
substitutes.
 Change your daily behavior, such as
avoiding other users.
 Engage in healthy behaviors.

Risks for Smokers and Nonsmokers
Both users and nonusers breathe environmental
tobacco smoke (ETS), or secondhand smoke,
which is air contaminated by tobacco smoke.
 Sidestream smoke, or smoke from the burning
end of a cigarette, pipe, or cigar, has high
concentrations of carcinogens, nicotine, and tar.
 Mainstream smoke, or smoke exhaled from the
lungs of a user, contains carcinogens, nicotine,
and tar.

Effects of Smoke on Nonsmokers

Smoke affects unborn children and infants.
 Nicotine
is passed through the placenta.
 Carbon monoxide reduces the oxygen levels
in the blood.
 Tobacco can impair fetal growth, causing
miscarriage, low birth weight, and premature
delivery.
 Infants may suffer from growth and
development problems throughout childhood.
continued

Smoke affects young children.
 Children
of smokers have a higher percentage
of sore throats, ear infections, and upper
respiratory problems.
 Children who live with smokers have double
the risk of developing lung cancer.
Reducing your Risks
Politely ask visitors who smoke to refrain
from smoking in your house or car.
 Use air cleaners or open the windows.
 Stay outside when visiting the home of a
smoker.
 Request being seated in the nonsmoking
section of restaurants.

Toward a Smoke-Free Society
Many states have passed laws prohibiting
tobacco use in public places.
 Laws prohibit the sale of tobacco to
minors.
 Tobacco licenses can be revoked when
stores sell tobacco to minors.

Working Toward National Health
Goals
The Department of Health and Human
Services has launched Healthy People
2010 to promote health and prevent
disease nationwide.
 By decreasing tobacco use and reducing
exposure to secondhand smoke,
individuals can increase their years of a
healthy life.
