Tobacco

3. Pick Your Poison!

4. Chemicals Found in Tobacco Smoke
with each puff on a cigarette, cigar or pipe, a smoker inhales over 4,000 different chemicals
Of these 4,000, at least 1,000 of them are known to be dangerous
The most deadly are known as nicotine, tar, and carbon monoxide

5. Chemicals Found in Tobacco Smoke
Acetaldehyde
Acetone
Ammonia
Benzene
Butadione
Ethylamine
Nitrogen dioxide
Hydrogen sulfide

6. Chemicals found in Tobacco Smoke
Formaldehyde
Vinyl chloride
Toluene
Hydrogen sulfide
Hydrocyanic acid
Methyl alcohol
Methylamine
Phenol

7. Nicotine
This is the drug in tobacco that acts as a stimulant and is addictive
STIMULANT: a drug that speeds up the activities of the central nervous system, the heart, and other organs
In its pure form, nicotine is one of the strongest poisons known
Taken in large amounts, nicotine can kill people by paralyzing their breathing muscles

8. Nicotine
Tolerance of nicotine can occur as early on as a second or third cigarette in a new smoker
As tolerance builds a person needs to smoke more and more to produce the same feeling
The Surgeon General ( the country’s highest medical authority) has said nicotine is as additive of a drug as heroin and cocaine

9. Nicotine Withdrawal This is a reaction of lack of nicotine
Symptoms includes head aches, irritability, restlessness, increased coughing, nausea, vomiting, a general feeling of illness, intense craving for tobacco
Withdrawal can begin as soon as two hours after the last cigarette
physical cravings reaches its peak in 24 hours

10. TAR

12. TAR
Tar is the dark stick mixture of chemicals that is formed when tobacco burns
Tar is the yellowish browning substance found on the fingers and teeth of smokers
it also sticks to the cells of the respiratory track where it damages cells\
The tar in tobacco smoke contains hundreds of chemical carcinogens

13. CARCINOGENS : cancer causing agents
Cancers of the lungs, throat and mouth are cause by the inhalation of tar and tobacco smoke

14. Carbon Monoxide

15. Carbon Monoxide
is a poisonous, colorless, odorless gas that is found in cigarette smoke
When carbon monoxide is inhaled it takes the place of large amounts of oxygen from your blood.
Carbon monoxide also makes it difficult for the oxygen left in your blood to get to your muscles and organs
When a person smokes it means the heart works harder but accomplishes less

16. Long Term Effects of Tobacco

17. Long Term Effects of Tobacco
tobacco products are directly responsible for the deaths of 400,000 Americans each year
Worldwide, 1 in 5 deaths are related to smoking health related problems

18. Cardiovascular Disease

19. Cardiovascular Disease
This is a disease of the heart and blood vessels that kills over 115,000 tobacco users each year just in the United States!
A smoker is three times more likely to suffer a heart attack than a non smoker
A heart attack is 5 times more likely to kill a smoker than a non smoker
Cardiovascular disease is caused by the weakening of blood vessels

20. Cardiovascular Disease
These blood vessels are weakened because the heart is doing so much more work to circulate and push blood throughout the blood of a smoker as opposed to a non smoker
Nicotine also promotes fatty build up in the walls of these blood vessels that cause blockages
These blockages are responsible for heart attacks

21. Respiratory Disease

22. Respiratory Disease many smokers suffer from dry and hacking coughs
Tar destroys the cilia in your respiratory tract ( little hairs that sweep away dust and other particles), these foreign particles are not cleared away and ingested causing a smoker to cough much more than a nonsmoker
A person can no longer clear the passage with their cough and mucus fills the bronchial tubes

23. Respiratory Disease
In time due to this cough the person will develop CHRONIC BRONCHITIS
This is a condition in which the bronchial tubes become swollen and clogged with mucus
People with chronic bronchitis find it difficult with fill their lungs with air
Simple activities such as walking stairs, may find themselves gasping for air

24. Respiratory Disease Here is currently no cure for chronic bronchitis
Smoking can lead to more serious disease such as EMPHYSEMA
This is a breathing disorder in which the small air sacs in the lungs loose their ability to expand and contract
Oxygen passes through the lungs and into the blood stream, while carbon dioxide passes through the air sacs and out of the body

25. Respiratory Disease
People with emphysema cannot give their body enough oxygen or rid their body of carbon dioxide
The damaged done to the lungs cannot be reversed
Even if the emphysema victim quits smoking the damage to the lungs is permanent

27. Cancer
Tobacco use is also a major factor in developing certain cancers
CANCER is an area of uncontrolled cell growth that invades the surrounding tissue and destroys it
Cancer can begin in any part of the body and travel to other areas
In the United States, lung cancer is known to be the most deadly form of cancer
