 Greater awareness of the negative health effects of
smoking, along with increased restrictions, has led to a
steady decline in rates of smoking
 Tobacco use tends to be more common among people
with lower levels of education and income.
 Most people who smoke begin between the ages of
11 and 15.
 Secondhand smoke- environmental tobacco smoke
(any smoke)

 Nicotine- an addictive drug found in tobacco leaves
and in all tobacco products
 Carbon monoxide- a poisonous, colorless, odorless gas
 Tar- a thick, oily, dark liquid that forms when tobacco
burns
 The nicotine in tobacco smoke travels quickly to the
brain, where it acts as a stimulant and increases heart
rate and breathing.
 Tobacco smoke also reduces the level of oxygen in the
bloodstream, causing a drop in skin temperature.
 Research has shown that smoking raises levels of
dopamine, a chemical in the brain, increasing feelings
of pleasure and reinforcing the desire to continue to
smoke.
 Nervous system- withdrawal symptoms (nervousness,
shakes and headaches) increased risk of stroke due to lack
of O2 to brain
 Circulatory system- HR increases, energy reduced because
less O2, blood vessels are weakened and narrowed and risk
of heart disease increases
 Respiratory System- shortness of breath, coughing, more
phlegm. Allergies, asthma and bronchitis increase. Lung
cancer, emphysema and COPD.
 Digestive System- upset stomach dulled taste and tooth
decay. Risk cancer of mouth and throat, stomach ulcers
and bladder cancer increases.
