What Is in Tobacco?

• Cigarettes contain 3 different components that
  cause harm to the body
• Nicotine
• the drug in tobacco. It is a stimulant and
  highly addictive
• Carbon monoxide
• a colorless, odorless, poisonous gas produced
  when tobacco burns
• Tar
• a sticky brownish liquid that coats any part of
  the body that smoke touches including the lining
  of the lungs and causes diseases

Tobacco Addiction
Nicotine is as addictive a drug as alcohol,
cocaine, or heroin. Nicotine addiction leads to
more diseases and deaths than all other
addictions combined. Reducing or cutting off
the supply of nicotine causes withdrawal.

8
Psychological Dependence
A tobacco user first becomes psychologically
dependent on tobacco. Psychological dependence
is an addiction in which a person believes that
he or she needs a drug in order to feel good or
function normally. To break a psychological
dependence on tobacco, users need to change their
habits.

9
Physical Dependence
Physical dependence is an addiction in which the
body develops a chemical need for a drug.
Physical dependence on tobacco is directly
related to nicotine. As a person continues to
use tobacco, the bodys tolerance for nicotine
increases. Tolerance is the bodys need for
larger and larger doses of a drug to produce the
same effect.

Tar can stick to any of these inside organs and
things within and around them such as the teeth
in your mouth and sinus cavities
Epiglottis Flap of tissue in back of mouth that
covers the trachea to prevent food from entering
it
Nose/Mouth Passages for air nose lined with
cilia
Bronchi Two tubes that branch from the trachea
one tube leads to each lung
Trachea Tube in throat that takes air to and
from lungs
Lungs Two large organs that exchange oxygen and
carbon dioxide
