Nicotine Addiction
What Causes Nicotine
Addiction?
 Nicotine is an addictive drug



Blood pressure
Heart rate
Flow of blood from the heart

What else does Nicotine do to
the Body ?
 Carbon monoxide reduces the amount
of oxygen the blood can carry
 Creates an imbalance between the
demand for oxygen by the cells and
the amount of oxygen the blood can
supply
How does Carbon Monoxide
increase the risk of heart
attacks?
 Hardening of the arteries:
 Carbon monoxide may damage the
inner walls of the arteries
 Encourages the buildup of fat in the
arteries
 Vessels narrow and harden
How does Nicotine increase the
risk of heart attacks?
 Causes several changes in the blood
that form blood clots
 Heart attacks and Strokes are more
likely
