Regular intake of alcohol causes an
individual to gradually tolerate a substantial quantity in the blood.
The brain gets used to alcohol. As a result, if you have drunk heavily
for years, you may be able to look and behave normally even though your
blood level would produce drunkenness in a person with a lower tolerance
for alcohol. Heavy drinkers who have built up a physical tolerance to
alcohol may talk coherently, but their ability to drive a car is still
impaired and progressive damage to the brain, liver and other organs
will still occur.
A negative result of
increased tolerance is that you become dependent on having a
concentration of alcohol in your blood. Your gradually need to drink
greater amounts to give you whatever effects you greater amounts to give
you whatever effects you expect from drinking. This dependence
degenerates into addiction and the greater levels of alcohol further
damage the organs of your body including the brain.
