Physiological Effects of Tobacco
HS 460
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) I.e. acetone, arsenic, benzopyrene,
phenol, tar, nicotine, etc.
Paralysis of Respiratory Cilia
i.e. acrolein, aldehyde, ammonia, nitrogen dioxide, hydrocyanic acid, etc.
Toxic Substances (poisons- over 200) i.e. nicotine, carbolic acid, CO2, CO,
methyl alcohol, etc.
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
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
Preteens (10%) Teenage years (80%) Post teen years (10%)
90% will start during college age years. If a person gets beyond their mid-twenties
and doesn’t smoke they probably won’t smoke.
Flavoring Agents (additives)
Almost every flavoring agent known to man has been added to tobacco
Most commonly- pipe tobacco
Filters
Usually end up with more tar and nicotine Explain- diagram on board
Pollution (several thousand pollutants identified in tobacco smoke) Anyone who claims to be concerned with
pollution and smokes is a hypocrite- with no qualifications
Loss of tissue elasticity Arteries
Greater increase CVD- heart attacks and strokes
AlveoliGreater increase in respiratory disorders
Bronchitis Asthma Lung cancer
Skin (leathery) Increase physiological aging process Increase skin cancer
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
Greater risk of frostbite in cold temperatures
Chronically- gangrene
