Products of Smoking Tobacco
• Nicotine - psychoactive stimulant
• Tar -sticky material resulting from the
smoking of tobacco
• Carbon Monoxide -toxic gas that
prevents blood cells from carrying
oxygen from the lungs
What is Nicotine
• Nicotine is one of 4000 chemicals found in the
smoke from tobacco.
• One of the most frequently used substances
and is one the most addictive.
• 1 Cigarette contains approximately 10 mg of
nicotine; 1 to 2 mg are available in the smoke.
• Nicotine is absorbed through the skin, mouth,
nose and/or lungs.
What is Nicotine
• Cigarette smoking delivers nicotine
to the brain in approximately 10
seconds.
• Cigar and pipe smokers typically
absorb nicotine through the mucus
membranes of the mouth.
Effects of Nicotine
• Initial stimulation of adrenal glands
resulting in the release of epinephrine.
Results in an increase in heart rate,
respiration, and blood pressure.
• Nicotine also causes the release of dopamine
resulting in the activation of the parts of the
brain responsible for pleasure.
Nicotine and Withdrawal
• Nicotine is metabolized quickly in the body.
• Nicotine users develop tolerance.
• Withdrawal symptoms:
– irritability, craving, cognitive deficits, sleep
disturbances, increased appetite.
• Symptoms start within a few hours and peak
within the first few days.
• 90% of smokers who try to quit without
treatment will fail.
Cost of Tobacco Use
Life
Tobacco use kills more than 430,000 people
annually - More than alcohol, cocaine, heroin, car
accidents, fire, and AIDS combined.
Economics
Smoking is responsible for over 50 million
dollars in health care costs annually
Medical Consequences (1)
• Tobacco use accounts for 1/3 of all cancers.
• Cigarette smoking is linked to 90% of all
lung cancer cases.
• Cardiovascular Disease (stroke, heart
attack, vascular disease, and aneurysm).
• 1/5 of all cardiovascular deaths are
attributable to smoking.
Medical Consequences (2)
• Asthma, chronic bronchitis, and
emphysema
Second Hand Smoke
• 3,000 annual deaths due to lung cancer in
non-smokers.
• 40,000 deaths related to cardiovascular
disease in non-smokers
Smoking and Pregnancy
• Interferes with the oxygen supply of
the fetus
• Developmental delays after birth
• Smokers are at a greater risk of
premature delivery.
• Decrease in infant birth weigh
Smokeless Tobacco and Cancer
• Cancer of the oral cavity and pharynx
accounts for about 3% of all new cancer
cases annually (30,500 per year).
• Only 50% of those diagnosed with oral
cancer will be alive 5 years later.
• The risk of developing oral cancer is 50%
higher for smokeless tobacco users.
Treatment
• Nicotine Replacement Treatments (gum,
inhalers, the “patch”.
• Non-Nicotine Therapies are used for
relief from withdrawal symptoms
(Zyban)
• Behavioral Treatment
