What Happens at Different Blood Alcohol Levels?

Blood alcohol concentration, or BAC, is the measure used to define how much alcohol is in a person’s blood. It is also used for legal purposes in a DUI or drunk driving case.  The more alcohol consumed, the higher the BAC level, because the body processes alcohol at a consistent rate, and drinking tends to outpace alcohol metabolism. When one drinks more than the body can process, alcohol levels rise and cause intoxication, leading to the possibility of driving drunk and DUI consequences.

BAC Levels and the effects:

.02 percent BAC: The body gets warm and somewhat relaxed, and judgment is altered slightly. Visual functions decline, as does the ability to multi-task.

.05 percent BAC: Inhibitions are lowered, as well as coordination and alertness. The eyes may be slower to focus or track objects, and reaction times are delayed.

.08 percent BAC: As the legal limit that defines intoxication, this BAC level shows significant problems with coordination. Speech, motor control, hearing, and vision are all affected, and reaction time significantly declines. This level of intoxication creates a true danger on the road.

.10 percent BAC: Speech is slurred, and, the ability to think or move appropriately has deteriorated. As this level is above the legal limit, there is a stronger danger involved and even less ability to make correct judgment calls.

.15 percent BAC: Considered a hardcore, high BAC level in many states in legal, DUI terms. Once a person reaches this level, they may already be vomiting, as well as exhibiting a true difficulty walking or even sitting.

.25 percent BAC and above: loss of consciousness, “alcohol poisoning,” and death are possible consequences to this level.

When drinking, keep in mind that the more one drinks, the less a person is able to judge one’s own level of intoxication. Understanding the effects of drinking on the body and mind. Then set a limit before drinking, and to stick with it, or plan for a safe ride home with a designated driver or taxi.
