Short term effects
(1 second for inhaled nicotine to get into the
bloodstream)
 Stimulates brain reward system
 Increases heart rate and blood
pressure
 Increases breathing rate
 Increases blood sugar levels
 Stimulates the vomit reflex
Long term effects
 1. Addiction-changes the way the
brain reward system functions
 2. Bronchitis-paralyzes then kills
cilia so mucus builds up in lungs
 3. Emphysema-air cannot move in
and out of the lungs because
alveoli are damaged
4. Heart and Artery Disease
 Nicotine increases heart rate,
narrows blood vessels and
eventually causes arteries to
become hardened and clogged
 Nearly 170,000 die yearly
Healthy
Unhealthy
5. Cancer
 Types that can be caused from
tobacco: Lung, Pancreas,
Bladder, Cervix, Kidney, Oral,

 Lung cancer often spreads to
other parts of the body; leading
cancer killer
6. Immune System Suppression
Reduces the activity of
immune system
Leads to susceptibility to
disease
7. Other

Effects of Smoke on Nonsmokers
 Sidestream smoke - smoke that

cigar, or pipe
 Mainstream smoke - smoke that is
inhaled through a tobacco product and
exhaled by a tobacco smoker
 Environmental tobacco smoke (second
hand smoke) - both of the above
Dangers of Second hand smoke
 Lung cancer-for every 8 smokers
killed by their own smoking, 1 nonsmoker is killed by exposure
 Headaches, nausea, dizziness, reduced
heart functions, asthma
Smoking during Pregnancy
 Chemicals pass through placenta to
fetus and affect fetus the same way
they affect the mother
 Can lead to miscarriage, premature
birth, low birth weight
 Baby at risk for SIDS
 Can affect fetus brain development
 May be addicted to nicotine at birth

 Funeral costs (20% of premature
deaths in the US are caused by
