Think Further
Myth or Fact?
The use of smokeless tobacco, hookah pipes, and
e-cigarettes is safer, healthier, and less addictive
than smoking cigarettes.
MYTH
– Fact: Smokeless tobacco is linked to cancers of
the oral cavity, throat, and digestive system.
– Fact: Hookah smokers are exposed to at least as
many toxins as cigarette smokers.
– Fact: Each method can cause addiction since
each delivers nicotine into the body.

Cardiovascular System
• Smokers are twice
as likely to die from
heart attacks as
nonsmokers
• Carbon monoxide
interferes with the
oxygen-carrying
ability of red blood
cells so the heart
receives less oxygen

How Nicotine Affects the Heart
Nicotine enters
bloodstream
Blood vessels
narrow and
adrenaline is
released
Heart and breathing
rates, and blood
pressure increase
Heart works harder
to pump blood
through body
Blood flow
restricted by buildup of fatty deposits
in vessel walls
Increased risk of
heart attack or
stroke

The Respiratory System
• Air travels through the
nasal cavity, pharynx,
larynx, trachea, and
into the bronchi in the
lungs
• Respiratory and
cardiovascular
systems deliver
oxygen to cells and
remove and expel
carbon dioxide

Lungs: Before and After Smoking
• Over time, smoking
damages the lungs
• The healthy lung
(left) belongs to a
nonsmoker and the
other is that of a
smoker
• Smoking during the
teenage years can
stunt the growth of
the lungs

substance to function
normally; psychological
dependence causes people
to believe they need a
substance to feel “normal”
