The document describes the effects of increasing blood alcohol concentration in 3 sentences: With a low blood alcohol concentration, there is some loss of judgment and relaxation. Moderate concentrations cause exaggerated behavior and impaired judgment, focus, and alertness. High concentrations result in poor muscle coordination, slurred speech, slowed thinking, and loss of balance, and very high concentrations cause major loss of motor control.

1. THE EFFECTS OF
BLOOD ALCOHOL
CONCENTRATION

2. Some loss of judgment;
relaxation, slight body warmth,
altered mood

3. Exaggerated behavior,
may have loss of small-
muscle control (e.g.,
focusing your eyes),
impaired judgment, usually
good feeling, lowered
alertness, release of
inhibition

4. Muscle coordination becomes poor
(e.g., balance, speech, vision,
reaction time, and hearing), harder
to detect danger; judgment, self-
control, reasoning, and memory are
impaired

5. Clear deterioration
of reaction time and
control, slurred
speech, poor
coordination, and
slowed thinking

6. Far less muscle control than normal,
vomiting may occur (unless this level
is reached slowly or a person has
developed a tolerance for alcohol),
major loss of balance
