Nicotine-A stimulant drug found in tobacco products including cigarettes and chewing tobacco.
Drug causing addiction (stimulant)
Colorless poison Increases heart
rate, blood pressure and breathing
Narrows blood vessels
Tar- A sticky, thick substance formed when tobacco is burned.
Cancer-causing chemical (carcinogen)
Slows the action of cilia
1 pack a day= 1 cup of tar in the lungs per year
Brown, sticky substance that coats the airway
Carbon Monoxide- Odorless, tasteless gas that
interferes with the ability of blood to carry oxygen. Odorless, colorless
gas Replaces the
oxygen in red blood cells
Shortness of breath Causes a build-up
of cholesterol in the arteries
Chemicals in smoke Acetones
An easily evaporated fragrant flammable liquid compound used to dissolve or to make chemical compounds.
Found in nail polish remover
Acetic Acid A colorless strong-
smelling liquid acid that gives the sour taste to vinegar and that is used especially in making chemical compounds (as plastics)
Ethanol A colorless
flammable easily evaporated liquid that is used to dissolve things and that is found in alcoholic beverages.
Formaldehyde
A colorless gas that consists of carbon, hydrogen, and oxygen, has a sharp irritating odor, and when dissolved in water is used to disinfect or to prevent decay.
Used as a preserver of body fluid.
Methane A colorless
odorless flammable gas that consists of carbon and hydrogen and is produced by decay of organic matter.
Methanol A light flammable
poisonous liquid alcohol that consists of carbon, hydrogen, and oxygen and is used especially as antifreeze and to dissolve things.
Napthalene
A hydrocarbon in the form of crystals usually obtained from coal tar and used in chemical manufacture and as a moth repellent.
Nitrobenzene A colorless
flammable liquid that evaporates easily and is used to make or dissolve other chemicals or as a motor fuel.
Nitrous oxide phenols
A white poisonous acidic compound present in tars from coal and wood that when dissolved to make a weak liquid mixture is used as a disinfectant.
Stearic Acid Acid obtained by
the breakdown of a hard fat.
Example of hard fat: The solid fat of
cattle and sheep used in soap, candles, and lubricants.
Chemicals in Smoke Project There are many chemicals
in cigarette smoke that are also found in other products. Find five examples of these products in magazines by using the “What’s in Cigarette Smoke?” worksheet as a reference. Cut the product out of the magazine to create a collage that represents a visual image of products that contain the same chemicals as cigarette smoke.
Respiratory System Definitions
Nose- The preferred entrance for outside air
into the respiratory system. Mouth
Oral cavity in which air also enters the respiratory system, especially when nasal passage may be temporarily obstructed, as by a cold or during heavy exercise.
Respiratory System Definitions
Throat Collects incoming air from the nose and mouth
and passes it downward to the windpipe.
Windpipe The passage leading from the throat to the
lungs.
Voice box Contains vocal chords and creates sound by
moving air.
Respiratory System Definitions
Alveoli Very small air sacs that are the destination of
air breathed in.
Esophagus The passage leading from the mouth and throat
to the stomach.
Ribs Bones supporting and protecting the chest
cavity and they help the lungs expand and contract.
Respiratory System Definitions
Diaphragm The strong wall of muscle that separates the
chest cavity from the abdominal cavity. By moving downward, it creates suction in the chest to draw in air and expand the lungs.
Bronchial Tubes There are one for each lung, which
subdivide into each lobe of the lungs.
Respiratory System Definitions
Bronchioles The smallest subdivisions of the
bronchial tubes at the end of which are the alveoli.
Epiglottis A flap of tissue that guards the entrance
to the windpipe, closing when anything is swallowed that should go into the esophagus and stomach.

Short-term Effects of Cigarette Smoking
Bad Breath Stale smell of tobacco
Odor of smoke on clothes, hands and hair
Deadened taste buds
Caused by constant exposure to heat, smoke and chemicals
Stuffy Nose Mucus build up
Irritated throat Mucus build up and
chemicals damage throat lining
Yellow fingers, nails and teeth Caused by tar
Long-term Effects of Cigarette Smoking
Wrinkled Skin Less oxygen in bloodstream
reaches the skin cells
Damaged Cilia Tar builds up and clogs cilia
Less Oxygen to Body
Cause headaches Decreases energy Breathing during activity is
difficult
Cuts heal slower Decreased blood circulation
Increased heartbeat Could cause heart attack
Drugs in body Nicotine gets into the brain
8 seconds after it is inhaled into the system
Sores in Mouth Caused by exposure to tar
and hot smoke in mouth
Diseases related to smoke Chronic Bronchitis
Inflamed mucus membrane in bronchial tubes
Mucus builds up/ paralyzes cilia
Bad Cough Can be cured if
cigarette smoking terminates
Emphysema Air sacs break
down/ become clogged and burst
Shortness of breath
Usually follows chronic bronchitis
Can not be cured
Diseases related to smoke Lung Cancer
Abnormal cell growth that destroys healthy cells
Tar irritates the lining of the lungs
85% of all lung cancer deaths are caused by smoking
Heart Disease Added workload
on the heart and blood vessels
Cholesterol build up
Stroke/ heart attack
Spit Tobacco Stains on teeth Tooth loss/ gum
disease Bad breath Mouth, lip, tongue,
gum cancers Leukoplakia (pre-
cancerous white spots in mouth)
Addiction
Smoking and its Effects on Pregnancy
Lower Birth Weight Slower to learn Stillborn is more
likely Pre-mature births Miscarriages Respiratory problems SIDS (Sudden Infant
Death Syndrome)
Benefits of Quitting Add years to life Lose smoker’s cough Improve stamina Improved sense of
taste and smell Bad breath goes
away More spending
money Higher self-esteem
Second Hand Smoke Second hand
smoke- cigarette smoke inhaled by a person who is not directly inhaling it from a cigarette.
Why is second hand smoke so dangerous? Second hand
smoke still contains the same chemicals.
