Morphine addiction
is caused by long term intake
of Morphine. Morphine is a narcotic
analgesic and highly addictive.
Tolerance (the need for higher
and higher doses to maintain the
same effect) and physical and
psychological dependence develop
quickly. Withdrawal from morphine
causes nausea, tearing, yawning,
chills, and sweating. Morphine
crosses the placental barrier,
and babies born to morphine-using
mothers go through withdrawal.
Addictive drugs
activate the brain’s reward
systems. The promise of reward
is very intense, causing the individual
to crave the drug and to focus
his or her activities around taking
the drug. The ability of addictive
drugs to strongly activate brain
reward mechanisms and their ability
to chemically alter the normal
functioning of these systems can
produce an addiction. Drugs also
reduce a person’s level
of consciousness, harming the
ability to think or be fully aware
of present surroundings.
