• What about e-cigarettes? – Some Washington counties have local laws that

prohibit the use of e-cigarettes in public places, just like cigarettes. As of March 2015, Whatcom County does not prohibit e-cigarette use in public places.

Think Further

The use of smokeless tobacco, hookah pipes, and e-cigarettes is safer, healthier, and less addictive than smoking cigarettes.

MYTH– Fact: Smokeless tobacco is linked to cancers of

the oral cavity, throat, and digestive system.– Fact: Hookah smokers are exposed to at least as

many toxins as cigarette smokers.– Fact: Each method can cause addiction since

each delivers nicotine into the body.

Myth or Fact?

Cardiovascular System

• Smokers are twice as likely to die from heart attacks as nonsmokers

• Carbon monoxide interferes with the oxygen-carrying ability of red blood cells so the heart receives less oxygen

shutterstock.com/BioMedical


How Nicotine Affects the Heart

Nicotine enters bloodstream

Blood vessels narrow and

adrenaline is released

Heart and breathing rates, and blood

pressure increase

Heart works harder to pump blood through body

Blood flow restricted by build- up of fatty deposits

in vessel walls

Increased risk of heart attack or

stroke


The Respiratory System

• Air travels through the nasal cavity, pharynx, larynx, trachea, and into the bronchi in the lungs

• Respiratory and cardiovascular systems deliver oxygen to cells and remove and expel carbon dioxide

Gas Exchange in Lungs

Body Scientific International, LLC


Critical Thinking

Which balloon best represents a smoker’s lung?

The balloon on the right is more like a lung damaged by smoking, which can’t hold as much oxygen as a healthy lung

Lungs: Before and After Smoking

• Over time, smoking damages the lungs

• The healthy lung (left) belongs to a nonsmoker and the other is that of a smoker

• Smoking during the teenage years can stunt the growth of the lungs

Carbon Monoxide


Toxic Chemicals Found in Tobacco Products Also Found in…

• Embalming fluid• Rat poison• Pesticides• Car exhaust • Lighter fluid• Battery acid• Nail polish remover• Road-paving material

• Hair dye• Mothballs• Rocket fuel• Paint• Rubber cement• Battery acid• Household cleaners


Smoking-Related Diseases

• Chronic Obstructive Pulmonary Disease • Chronic bronchitis (bronchial tubes become

swollen and irritated and pathways to lungs narrowed)

• Emphysema (sacs of air in lung tissue are destroyed)

• Lung Cancer• Abnormal cells grow rapidly and form a mass of

cells, or tumor, that interferes with breathing


Immune System

• Smoking weakens immune system — organs, tissues, and cells that fight off disease-causing agents

• Smokers get sick more often than nonsmokers

Why People Use Tobacco

Lesson 9.2


Addiction

• Each day in the United States, • 3,200 teenagers smoke their first cigarette • 2,100 teenagers and young adults who were

occasional smokers become daily smokers

• Yet 9 out of 10 teenagers do not smoke


Four Stages of Substance Abuse

1

• Experimentation• User uses a substance “just to try it”

2

• Regular Use• User develops habit of regularly using substance

3

• Tolerance• User’s body needs more and more of substance to

achieve the same effects

4

• Dependency and Addiction• User relies on the substance to function or feel “normal” • Habit interferes with personal responsibilities and

relationships

The Slippery Slope to Addiction


Critical Thinking

What is a physical versus a psychological dependence?

Dependence is physical when the body needs a certain amount of a substance to function normally; psychological dependence causes people to believe they need a substance to feel “normal”

Social Factors

• Parents’ attitudes• Friends and peers

– Teens who have friends who smoke are much more likely to smoke themselves

Treating and Preventing

Nicotine Addiction

Lesson 9.3


Benefits of Quitting

• Within days of quitting, • blood pressure and

heart rate decrease• coughing abates

• Within a year of quitting,• risk of heart attack and

cancer decrease

Treating Nicotine Addiction

• Nicotine replacement• Examples: Nicotine

gum and nicotine patch

• Medication• Drugs help smokers

cope with withdrawal symptoms

Treating Nicotine Addiction

avoiding tempting situations– Response substitution, or

substituting smoking with stress management, relaxation, and coping skills

Critical Thinking

What resources can smokers use to quit?

• Individual and group counseling

• School guidance counselors

• Doctors• Telephone helplines• Online resources

Prevention

• Close to 90% of adults who smoke regularly had their first cigarette by 18 years of age

• Prevention is the best way to reduce the smoking rate


Government-Based Strategies

• Banning the sale of tobacco products (to people younger than 18 years of age, for example)

• Banning smoking in public places• Increasing taxes on cigarettes• Requiring warning labels on packaging• Mass media antismoking campaigns

Disadvantages of Smoking

• Many nonsmoking teens view smoking as “gross”

• 8 in 10 eighth graders surveyed said they prefer to date people who do not smoke

Smoking and Your Wallet

• Pack of cigarettes costs between $5 and $14, depending on local tax rates

• Cost of a pack-a-day habit at $7 a pack:• $213 per month• $2,557 per year• $25,570 per decade


Social Costs of Tobacco Use

• One-half million adults will die prematurely from smoking this year

• Total economic costs due to tobacco are over $289 billion a year

Critical Thinking

Research and Calculate

Figure out the financial cost of a pack-a-day habit in your area:

• per month• per year• per decade

Refusal Skills

• Make sure people know you don’t want to use tobacco or breathe secondhand smoke

• Firmly explain your reasons for not smoking and stick to your decision

• Imagine situations in which you are offered tobacco and practice your responses


Refusal Phrases

• “No, thanks... • I want to keep my lungs in peak condition for

[insert sport or activity].”• I don’t want my hair, clothes, and breath to

smell like cigarettes.”• I like my lungs. I don’t want to damage them.”


Think Further

What other words can you use to turn down an offer of a tobacco product?

What body language can you use to reinforce your words?

Literacy and Critical Thinking Skills

• Tobacco companies make products, such as flavored cigars and cigarettes, that appeal to young people

• To counter this, think critically about tobacco products and messages from tobacco companies
