Tobacco and it’s effects

By Todd Corabi

Some information taken from Glencoe Health pre-made powerpoints from Teen Health series

FACT: Smoking and Obesity are the 2 single highest causes of preventable death in the United States.

Forms of tobacco
Forms of Tobacco

Tobacco products are made from the Tobacco plant. The can be smoked, inhaled, chewed and absorbed.

  • Products that are smoked:

    • Cigarettes

    • Cigars and pipes

  • Smokeless products:

    • Chewing tobacco

    • Snuff, dip, “spit”


Cigarettes (which most of this powerpoint will focus on) are made from shredded tobacco leaves.

A single puff of tobacco smoke contains

more than 4000 chemicals

Most of these chemicals prevent the body

from functioning the way it should

Between 43-80 these chemicals cause cancer

In the United States, more than 400,000 people die each year because of smoke-related illnesses.

Why teens begin using tobacco
Why Teens Begin Using Tobacco

Wanting to look “cool”


Wanting to be just like a favorite celebrity

Parents or family members use tobacco

Too hooked to be able to quit

Other…see below

Other: readily available, social settings, to fit in, do not believe facts, addicted due to second hand smoke?

What is in tobacco
What Is in Tobacco?

Cigarettes contain 3 different components that cause harm to the body


the drug in tobacco. It is a stimulant and highly addictive

Carbon monoxide

a colorless, odorless, poisonous gas produced when tobacco burns


a sticky brownish liquid that coats any part of the body that smoke touches including the lining of the lungs and causes diseases

Cigars and pipes
Cigars and Pipes

Although most of this power point concerns cigarettes, shredded tobacco leaves are also used in cigars and pipes.

Dangers of using cigars or pipes:

  • Cigar smoke contains 25 times more carbon monoxide and up to 400 times more nicotine than cigarette smoke.

  • Cigar and pipe smokers are more likely to develop cancers of the lip, mouth, and tongue than nonsmokers.

Tobacco addiction
Tobacco Addiction

Nicotine: type of drug = stimulant

is as addictive or more so a drug as cocaine or heroin.

Nicotine addiction leads to more diseases and deaths than all other addictions combined.

Reducing or cutting off the supply of nicotine causes withdrawal.

Psychological dependence
Psychological Dependence

A tobacco user first becomes psychologically dependent on tobacco.

Psychological dependence leads to addiction because a person believes that he or she needs a drug in order to feel good or function normally although they really do not

To break a psychological dependence on tobacco, users need to change their habits.

Physical dependence
Physical Dependence

Physical dependence is an addiction in which the body develops a chemical need for a drug.

Physical dependence on tobacco is directly related to nicotine.

As a person continues to use tobacco, the body’s tolerance for nicotine increases.

Tolerance is the body’s need for larger and larger doses of a drug to produce the same effect.

Parts of the respiratory system

Tar can stick to any of these inside organs and things within and around them such as the teeth in your mouth and sinus cavities

Parts of the Respiratory System


Flap of tissue in back of mouth that covers the trachea to prevent food from entering it


Passages for

air; nose lined

with cilia


Two tubes that branch from the trachea; one tube leads to each lung


Tube in throat that takes air to and from lungs


Two large organs that exchange oxygen and carbon dioxide

Harmful substances in tobacco smoke

Harmful chemicals include but are not limited to….. within and around them such as the teeth in your mouth and sinus cavities

  • Increases Heart Rate, Blood Pressure and Breathing Rate

  • Activates Fight or Flight Response

  • Increases alertness (makes you hyper)

  • Decreases Digestive System

  • Tricks people to think they are relaxed

  • Bad Breath

  • Smell on clothes, hair and skin

  • Lowers amount of Oxygen going into body

Respiratory System within and around them such as the teeth in your mouth and sinus cavities

Tobacco smoke damages

the alveoli. This damage may

lead to emphysema.

Smokers are also between

12 and 22 times more likely

than nonsmokers

to develop lung


Some long term effects of smoking include………………

of cavities and gum

linked to cancers

of the mouth, throat,

esophagus, stomach,

and pancreas.



Tobacco use is

linked to

heart disease.

Excretory System

Smokers have at least

twice the risk of

developing bladder

cancer as nonsmokers.

Smokeless tobacco

can also put users

at risk of developing

bladder cancer.

Nervous System

Tobacco use reduces

the flow of oxygen

to the brain, which

can lead to a

Common Problems of the Respiratory System associated with smoking

Disease or




is a chronic inflammation of the bronchi (medium-size airways) in the lungs.




Disease in which alveoli harden and disintegrate; symptoms include extreme difficulty breathing; almost entirely caused by smoking

No known cure;

very low

Lung Cancer

How tobacco affects nonsmokers cont d
How Tobacco Affects Nonsmokers (cont’d.) smoking

Exposure to secondhand smoke causes people to become passive smokers.

Passive smoking is harmful because:

  • It can cause respiratory problems, including lung cancer, just like smoking.

  • It may irritate the nose and throat and cause itchy and watery eyes, headaches, and coughing.

Rights of nonsmokers
Rights of Nonsmokers smoking

As a nonsmoker, you have the right to:

  • Breathe air that is free of tobacco smoke.

  • Express your preference that people not smoke around you.

Rights of nonsmokers cont d
Rights of Nonsmokers (cont’d.) smoking

Laws protecting the rights of nonsmokers:

  • In 1989, the federal government banned smoking on all domestic airplane flights.

  • Almost every state government has put restrictions on smoking.

  • Employers have a legal right to restrict smoking in the workplace, and many have banned smoking.

Children and unborn babies
Children and Unborn Babies smoking

Tobacco use during pregnancy is associated with the following:

  • Increased chance of miscarriage

  • Increased chance of stillbirth

  • Low birth weight.

Children and unborn babies cont d
Children and Unborn Babies (cont’d.) smoking

Infants whose mothers smoke during and after pregnancy are three times more likely to die from a condition known as Sudden Infant Death Syndrome than are infants whose mothers do not smoke.

Children of smokers experience higher rates of allergies, asthma, chronic bronchitis, ear infections, and heart problems.
