• The Health Risks of
• Tobacco Use

Health Risks of Tobacco Use

• About 23 of high school students and 10 of
  middle school students are current smokers
• About 1/3 of children and teens who try
  cigarettes become regular smokers
• About 9.9 of high school boys and 1.2 of high
  school girls use smokeless tobacco

All forms of tobacco contain chemicals that are
dangerous to your health

• Addictive drug stimulant
• Nicotine
• Tar
• Carbon Monoxide
• Smokeless Tobacco
• Carcinogen
• Leukoplakia
• Harmful Effects long- and short-term
• Other consequences

4

• Addictive Drug - A substance that causes
  physiological or psychological dependence
• Nicotine - An addictive drug found in all tobacco
  leaves (used in all tobacco products)
• Stimulant - A drug that increases the action of
  the central nervous system, the heart, and other
  organs ( blood pressure, heart rate)
• Carcinogen - A cancer-causing substance (same
  poisonous compounds found in rat poison, paint,
  and toilet cleaner)

5

• Tar- A thick, sticky, dark fluid produced when
  tobacco burns (how does this cooperate with your
  pink, healthy lungs?)
• Carbon Monoxide - A colorless, odorless, and
  poisonous gas (deprives body tissue and cells of
  oxygen how do you breathe?)
• Smokeless Tobacco - Sniffed through the nose,
  held in the mouth, or chewed (sometimes called
  spit absorbed into blood through mucous
  membranes)
• Leukoplakia - Thickened, white, leathery-looking
  spots on the inside of the mouth can develop
  into oral cancer

6

• Short-term and Long-term effects

SHORT-TERM LONG-TERM
Brain chemistry changes Chronic Bronchitis
Respiration and Heart rate increase Emphysema
Taste buds are dulled/appetite reduced Lung cancer
Bad breath and yellow teeth Coronary heart disease
Smelly hair, skin, clothes Weakened immune system
7
Other Consequences of Tobacco Use

• Costs to society
• In U.S., lost work/productivity - about 165
  billion/year
• Cost to individual
• One pack a day (4-11 approx.) for 1 year ?
• Legal consequences
• Selling cigarettes to someone under age 18 is
  illegal. Using tobacco products on school campus
  will lead to suspension.

• Chapter 20, Lesson 2
• Choosing to Live
• Tobacco-Free

9
Teens and Tobacco

• Why do some teens begin to smoke?
• falsely think it will help control weight
• cope with stress
• seem more mature and independent
• Actually
• smoking reduces capacity to physical activity
  (leads to weight gain)
• nicotine dependency leads to stress levels
• Media influences behaviors is it glamorous or
  make you look cool?

10
Reduced Tobacco Use Among Teens

• Tobacco Legislation 1998 legal settlement
  restricting tobacco advertising aimed at young
  people also required to fund ads that discourage
  smoking
• No Smoking policies limited smoking areas
  (restaurants, airports, public places)
• Family Values if parents dont smoke more than
  likely you wont either
• Positive Peer pressure healthy role models
• Health risks knowledge is power understanding
  about diseases and health problems

11
Benefits of Living Tobacco-Free

• Better cardiovascular endurance and lung function
• Improved fitness level and athletic performance
• Reduced risk of lung cancer, heart disease, and
  stroke
• Improved mental/emotional state not dependent
  on drug sense of freedom!
• Less stress (less worry)

Tobacco

• Chapter 20, Lesson 3
• Promoting a
• Smoke-Free Environment

13
Health Risks of Tobacco Smoke

• Environmental tobacco smoke (ETS) also known as
  second-hand smoke is air contaminated by
  tobacco smoke
• mainstream smoke - smoke exhaled from lungs of a
  smoker
• sidestream smoke - smoke from the burning end of
  a cigarette, pipe, or cigar
• Which type of smoke is more dangerous? Why?

14

• ETS from cigarettes, pipes, or cigars contain
  more than 4,000 chemical compounds, 50 of those
  are carcinogenic (cancer-causing)
• Second-hand smoke causes about 3,000 deaths from
  lung cancer each year.
• ETS causes eye irritations, headaches, ear
  infections, coughs it worsens asthma and other
  respiratory problems and increases coronary heart
  disease

15
Health Risks to Unborn Children and Infants

• Smoking during pregnancy
• impaired fetal growth
• spontaneous miscarriage
• prenatal death
• premature delivery
• low birth weight
• deformities
• stillbirth
• SIDS (sudden infant death syndrome)
• severe asthma attacks, ear infections,
  respiratory tract infections
• Nicotine passes through placenta (constricting
  blood vessels)
• Carbon monoxide reduces oxygen levels in the
  blood

16
Health Risks to Young Children

• Children of smokers
• higher levels of poor overall health
• more sore throats, ear infections, upper
  respiratory problems
• slows lung development (weaker lungs)
• children learn by example
• ETS (second hand smoke)

17
Creating a Smoke-Free Society

• Healthy People 2010 reduce tobacco use and
  related deaths
• In most states, it is illegal to sell tobacco to
  teens (under 18 years of age) illegal to smoke
  in public places
• Community activities that promote healthy
  lifestyles
• Encourage others to avoid tobacco use
