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
