Reminders about today’s lecture
• If you want to ask a question or comment, raise your hand
• Be respectful of others• This is a long lecture so stay
focused so we can finish on time!
Did you know?
• More than 1,000 people in the U.S. die each day from smoking-related illness
• Smoking kills more people each year than AIDS, fires, car accidents, murders, suicides, alcohol and other drugs combined.
Cigarette Facts • There are over 4,000 chemicals in
cigarettes• Nicotine is what makes them addictive.• Each cigarette smoked shortens the
users lifespan by 11 minutes.• About half of cigarette smokers die of
tobacco-related disease and lose on average 14 years of life.
What is in tobacco and cigarettes?Lots of toxic chemicals!
• Carbon Monoxide-auto exhaust, gas chambers
• Carbon Dioxide • Carbonyl Sulfide • Benzene (1) Toluene-industrial
solvent, in explosives• Formaldehyde (2)- body tissue
preserver • Acrolein-aquatic herbicide=burned
glycerol • Acetone-poisonous solvent, nail
polish remover • Pyridine-poisonous solvent• Methylpyridine-insecticide solvent• Vinylpyridine • Hyrogen Cyanide-rat poison, gas
chambers • Hydrazine-rocket fuel chemical
• Ammonia-poisonous, cleaning agent for toilets and floors
• Methylamine-tanning agent • Dimethylamine-tanning accelerator • Nitrogen Oxides• Nitrosodimethylamine• Nitrosodiethylamine• Nitrosopyrrolidine• Formic Acid-caustic solvent• Acetic Acid-caustic solvent • Methyl Chloride-poisonous refrigerant• Butadiene Particulate Matter-animal
carcinogen • Nicotine-insecticide, cockroach killer• Anatabine Phenol-toilet bowl
disinfectant
• Catechol-tanning, dyeing agent • Hydroquinone-photographic
developing agent • Aniline-industrial solvent• Toluidine-agent in dye manufacture • Napthalamine-mothballs • Aminobiphenyl • Benz(a)anthracene • Benzo(a)pyrene • Cholesterol • Butyrolactone • Quinoline-specimen preservative• Harman • Nitrosonornicotine • NNH • Nitrodiethanolamine • Nickel • Zinc-anti-corrosion coating for
metals • Aluminum-metal • Titanium-metal • Copper-metal • Mercury-metal
• Silicon-metal • Silver-metal • Gold-metal • Polonium-210-radioactive element• Benzoic Acid-tobacco curing agent• Lactic Acid-caustic solvent• Glycolic Acid-metal cleaning agent• Succinic Acid-agent in Lacquer
manufacture• PCDDs and PCDFs –dioxins,
dibenzofurans Hexamine-barbecue lighter
• Stearic Acid-candle wax • Cadmium-rechargeable batteries• Arsenic-poison • Butane-cigarette lighter fluid• Propylene Glycol-antifreeze
Why do people smoke and chew?
• Advertisements make it look attractive• Peer pressure• Some people think it helps with weight
control• Some people think it helps reduce stress• Their parents do it• Rebellion
Economic Effect of Smoking
• If a pack of cigarettes is about $9/pack…
• If you smoke 1 pack a day:– That’s $9 x 7 days/week = $63 a
week– That’s $63 x 52 weeks/year =
$3,276 a year!
Short term effects of smoking:
• Wrinkled skin• Less taste• Stained fingers• Decreased sense of smell• More colds• Yellow teeth• Stinky clothes
Effects of smoking on the respiratory
system• Smoking is directly linked to – Chronic obstructive pulmonary disease
(COPD)– Emphysema– Cancers (lung, larynx (voicebox) mouth,
and pancreatic)
• Furthermore, the earlier and the higher level of tar content in the tobacco filled cigarettes causes the greater risk of these diseases.
• Beware: – THE FOLLOWING PICTURES MAY BE
DISTURBING– DON’T LOOK IF YOU WILL GET
QUEASY!

How it damages our respiratory system components:• Cilia – cigarette smoke paralyzes them so
they can’t clean out your lungs. This causes harmful particles in cigarette smoke to sit in your lungs and form tar.
• Also effects our Bronchioles & Alveoli – Emphysema causes the small airways to collapse during forced exhalation, as alveolar collapsibility has decreased. People with this disease don't get enough oxygen and cannot get rid of the carbon dioxide, so they always have a shortage of breath. As a result, airflow is impeded and air becomes trapped in the lungs, in the same way as other obstructive lung diseases.
Lung Cancer• Very deadly because it’s hard to diagnose
early• There are over 19 known chemical
carcinogens in cigarette smoke.• Lung cancer is the most common cause of
cancer-related death (1.3 million deaths worldwide annually, as of 2004.)
• Almost 90% of lung cancer deaths are caused by smoking.
• Symptoms are shortness of breath, coughing (including coughing up blood), and weight loss.
• Non-smokers can also get lung cancer from secondhand smoke.
Emphysema• disease of the lung tissue caused by
destruction of bronchioles• Causes the small airways to collapse
during forced exhalation, as alveolar collapsibility has decreased.
• Symptoms include shortness of breath on exertion, and an expanded chest.
• Most of the people who have emphysema are smokers.
• Damage caused by emphysema is permanent even after the person stops smoking.
Smoking while pregnant• Can cause miscarriages • Contributes to a number of other threats to the health
of the fetus • premature birth• low birth weight• Sudden Infant Death Syndrome (SIDS).• mental and physical disabilities.
• Secondhand smoke is also bad for the baby
How smoking damages our other systems:• Cardiovascular –• Clogged arteries• Hypertension (high blood pressure)• Heart disease (heart attacks, coronary
artery disease)• Decreased oxygen to blood and rest of
body
• Immune – • Nicotine acts as an immunosuppressant
(this is why smokers can get sick easier than nonsmokers)
Effects of smoking marijuana on the respiratory system• Marijuana smoke and cigarette smoke contain many of the
same toxins, including one which has been identified as a key factor in the promotion of lung cancer.
• This toxin is found in the tar phase of both, and it should be noted that one joint has four times more tar than a cigarette.
• Moore et. Al (2005) - Marijuana users have similar rates of respiratory symptoms as tobacco cigarette users even though they were 10 years younger.• Chronic bronchitis, COPD & cancer• Most heavy marijuana smokers were also cigarette
smokers (77%)• Those that smoked both had a higher incidence of
respiratory symptoms than just tobacco users
