CigarettesEach puff contains 4,000

chemicals; at least 43 of these are known to cause cancer.

nicotine Is the Addictive substance in cigarettes. People smoke to reduce their craving for

nicotine. A Stimulant Speeds up the Central Nervous System (CNS) Causes increase in blood pressure and heart

rate.

nicotine and smoking It takes 5-7 seconds for nicotine to reach the

brain nicotine is absorbed into the blood stream

through the lining of the mouth and lungs nicotine causes the blood pressure to rise and

the heart rate to increase up to 20 beats per minute

nicotine and smoking nicotine causes a decrease in oxygen supply

to the cells The rush of stimulations of the brain is

followed by a depression and fatigue-this leads the smoker to seek more nicotine

tar Is the flavor-producing agent in cigarettes It is a thick dark fluid that is produced when

tobacco burns. Several substances in tar are carcinogens Penetrates smoker’s airways and lungs

paralyzing or destroying the cilia.

carbon monoxide Odorless, poisonous gas in cigarette

smoke Passes through the lungs into the blood Prevents the red blood cells from

carrying oxygen to the body’s cells

Pipes and CigarsThere is a higher incidence of mouth,

lip, and throat cancer found in cigar and pipe smokers

Pipes and cigars generate more tar and other chemicals than cigarettes

Inhaling pipe or cigar smoke is more dangerous that cigarette smoke

“Specialty Cigarettes”Have a stronger tobacco and have

spices like cloves vanilla addedThe cloves in clove cigarettes

anesthetize the throat and allow for deeper inhalation

Dangers of Smoking(ANYTHING!)

EVERYDAY at least 1,000 people DIE from diseases caused by smoking

Approx. 400,000 deaths per year are attributed to smoking

Smoking and the Respiratory System

Smoking is associated with 2 chronic obstructive pulmonary diseases:

•1. Chronic Bronchitis

•2. Pulmonary Emphysema

Chronic BronchitisOccurs when the bronchi are irritated

because the cilia have become useless due to a build up of tar.

This situation causes chronic coughing and excessive mucous secretion of the bronchial tree.

Pulmonary EmphysemaCaused by the destruction of the tiny

oxygen absorbing sacs in the lungs.This situation makes it very difficult to

BREATH!

Lung Cancer

Lung cancer begins when the bronchi are irritated by cigarette smoke

Cilia are destroyed and mucous cannot be expelled-a cough develops

Cancerous cells grow in these conditions, block the bronchi and move into the lungs

Lung Cancer 75% of deaths from lung cancer in women are

caused from smoking Smokers are 10 to 15 times more likely to

develop lung cancer People who smoke 2 or more packs per day

are 20-25 times more likely to get lung cancer Male smokers between the ages of 30 and 40

can expect to loose 8 years off their life

Smoking and the Circulatory System

Nicotine speeds up the pulse making the heart work harder

Smoking constricts the blood vessels cutting down on blood flow to the limbs

Smoking and the Circulatory System

Nicotine contributes to plaque build up in blood vessels-causing hardening of the arteries and increasing risk of heart attack

Smoking also damages the heart muscle itself Raised blood pressure increases the risk of

stroke

Dangers of Smokeless Tobacco

Leukoplakia- tobacco irritates sensitive tissue of the mouth and is responsible for leukoplakia, which are thickened, white, leathery spots inside the mouth.

These are areas can develop into cancer of the mouth.

Dangers of Smokeless Tobacco

More saliva is produced and some gets into the digestive and urinary tracts-this introduces tar and other harmful chemicals

Greater tooth wear because of gum damage

Dangers of Smokeless Tobacco

Lip cancerCancer of the mouthStained teethBad breathGum diseaseCancer of the cheek and jawbones

Second Hand Smoke

Passive Smoke-smoke that remains in a closed enviornment after a smoker is finished

Passive smoke is made up of both mainstream smoke and sidestream smoke.

Second Hand Smoke Mainstream Smoke- smoke that is blown off by

a smoker Sidestream Smoke- smoke from a burning

cigarette. Sidstream smoke is more dangerous than

mainstream smoke because it has not passed through a filter!!

FACTSSecond Hand Smoke

A non-smoker breathing in a room containing passive smoke could have inhaled enough tar and nicotine in an hour to have smoked a whole cigarette

Non-smokers may develop the same health problems as smokers

FACTSSecond Hand Smoke

Passive smoke can worsen or cause heart disease

Non-smokers living with smokers have a higher risk of heart disease

Each year, 37,000 non-smokers die from heart disease due to passive smoke

Kicking the Habit!!!(Please)

Withdrawal-happens when a person who is physiologically dependent on a substance stops using that substance.

During that period a person might feel nervous, moody, or have difficulty sleeping.
