“The Effects of Tobacco use”
Lesson 1
Tobacco Use-A Serious Health Risk
Tobacco Use is the #1 cause of preventable disease and death in the
US. It is attributed to roughly 438,000 deaths per year, or 1 out of 5
deaths overall.
 Worldwide, tobacco use causes more than 5 million deaths per year.
 On average, adults who frequently smoke cigarettes die 14 years
earlier than nonsmokers.
Addictive drug-is a substance that causes, physiological or
psychological dependence.
(Physiological=body, Psychological =mind)
Nicotine=the addictive drug found in tobacco products.
It is classified as a Stimulant-which is a drug that raise blood pressure,
increase heart rate, and contributes to heart disease and strokes.
Cigarette Smoke-A toxic mix
Carcinogens-are cancer causing substances
 Tar-a thick, sticky, dark fluid produced when tobacco
burns
 Carbon monoxide-a colorless, odorless, and
poisonous gas. When smoking Carbon monoxide is
taken up more by the blood than
oxygen, thereby depriving the
cells of oxygen.
 Prune juice can be added a
flavoring
 There are more than 4000
toxic chemicals in Cigarettes
Smokeless Tobacco……..
 Is Tobacco that is sniffed through
the nose or chewed. It carries
the same risks as cigarettes
including addiction to nicotine.
 Health risks include but are not limited to: Lip
and throat cancer, damage to teeth and gums
and digestive system.
 Leukoplakia-Thickened white, leathery
looking spots on the inside of the mouth.
How about a Dip…?
Leukoplakia
Short Term Affect on the body
 Changes Brain chemistry body craves more
 Withdrawal symptoms
In a s little as 30 minute after last use.
 Increased respiration and heart rate
 Dulled taste buds
 Bad breath, smelly clothes,
hair, and skin
Long Term Affects on
the body
Diseases of the
Respiratory System (Lungs)
 A. Chronic Bronchitis: is an irritation of the bronchi. The cilia
become useless; tar builds up causing a chronic cough and excessive
mucus.
 B. Emphysema: is a condition which destroys the tiny air sacs in the
lungs. These air sacs are needed to absorb oxygen into the blood
stream. A person with advanced emphysema can use up to 80% of
their energy just to breath.
 C. Lung Cancer: is the leading cause of caner deaths in males. Cilia
are destroyed and extra mucus can not be expelled. Cancer cells grow
in these conditions, block the bronchi and move into the lungs.
 African Americans tend to suffer most from Tobacco related lung caner
Diseases of the Circulatory System
(Heart)
 Nicotine makes the heart work harder
and speeds up the pulse.
 Smoking constricts the blood vessels, which cuts down on
circulation.
 Nicotine contributes to plaque build up in blood vessels. This
leads to hardening of the arteries. This condition increases the
risk of a heart attack.
 Nicotine also increases blood pressure and can lead to strokes.
Nervous System
 Addiction
 Increase risk of strokes-
which occur in the
Brain
Digestive system
 Possible mouth, pharynx, larynx, stomach,
pancreas cancers
 Increased nausea,
diarrhea
Other consequences
Under 18-it’s illegal
 Smoking 1 ½ packs a day is
similar to have 250 chest X-rays
Socially consequencesLoss of friends, ignored
Excluded
Financial problemsLoss of money from your
Pocket due to high cost of cigs
Over$2000/yr for a pack a day
Smoking during Pregnancy
 *Causes low birth weight babies
 *High rate of respiratory infections in babies
 *Small fetal growth
 *Increase chances of Spontaneous abortion
 *Prenatal deaths
 *Growth and developmental
problems during early
childhood.

by teens?

clues? Are they aware of these clues? Why or Why
not?
