“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 4000toxic chemicals in Cigarettes

Smokeless Tobacco……..

Is Tobacco that is sniffed throughthe nose or chewed. It carries the same risks as cigarettesincluding 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 bodyDiseases 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 consequences-

Loss of friends, ignored

Excluded

Financial problems-

Loss 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.
