Tobacco related deaths are the single most preventable cause of death in the world.
  • Annually in the United States
    • More than 419,000 tobacco related deaths including more than 53,000 deaths from second hand smoke
carcinogenic agents several hundred
Carcinogenic Agents (Several Hundred)
  • I.e. acetone, arsenic, benzopyrene, phenol, tar, nicotine, etc.
paralysis of respiratory cilia
Paralysis of Respiratory Cilia
  • i.e. acrolein, aldehyde, ammonia, nitrogen dioxide, hydrocyanic acid, etc.
toxic substances poisons over 200
Toxic Substances (poisons- over 200)
  • i.e. nicotine, carbolic acid, CO2, CO, methyl alcohol, etc.
respiratory tract irritations
Respiratory Tract Irritations
  • Formic acid
  • Tars (pyridine)
  • Glycerin
  • Dyethylene glycol
those substances also lead to
Peptic ulcer irritation

Low child birth weight

Premature births

Miscarriage

Still births

Neonatal deaths

Cancer

20% of the unsuccessful pregnancies would have been successful had the mother not smoked

Those substances also lead to:
child birth
Child Birth
  • Smoking Mother
    • Low birth weight
    • Premature births
    • Still births
    • Neonatal deaths
  • Smoking Father (non-smoking mother-no second hand smoke)
    • Greater increase in child birth problems (similar to but lower than that of smoking mother)
  • Second hand smoke
    • Greater increase in child birth problems
age people begin smoking
Age people begin smoking
  • Preteens (10%)
  • Teenage years (80%)
  • Post teen years (10%)
    • 90% will start during college age years.

Loss of tissue elasticity
  • Arteries
    • Greater increase CVD- heart attacks and strokes
  • Alveoli
    • Greater increase in respiratory disorders
      • Bronchitis
      • Asthma
      • Lung cancer
  • Skin (leathery)
    • Increase physiological aging process
    • Increase skin cancer
heart stimulant
Heart Stimulant
  • Potentially increase pulse greater than 30 beats/min.
    • Duration of greater than 30 min.
  • Exercise similar increase in beats/min.
    • Duration of 5 min. or less
  • Smoking results in no physiological benefits
vasoconstrictor
Vasoconstrictor
  • Greater risk of frostbite in cold temperatures
  • Chronically- gangrene
