Why do TEENS Smoke? Peer Pressure Relaxation Influence of advertising and the media They feel that they are indestructible They believe that the bad effects only
happen to older people who have smoked for several years
They believe they can STOP at any time
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.
The symptoms of withdrawal do not last a long time!
