Alcoholism
People who can no longer control their use of
alcohol suffer from the disease known as
alcoholism.
Physically, an alcoholics body requires alcohol
to function.
Psychologically, alcoholics consider drinking a
daily part of life.

TOLERANCE to the effects of alcohol; making the
drinker consume more alcohol to experience the
original effect.
With increasing TOLERANCE and use of alcohol
DEPENDENCE develops. This is when the drinker
becomes DEPENDENT on the alcohol everyday.
Finally ADDICTION results, where control of
drinking is lost.
