BAC Statistics

Blood Alcohol Concentration

Commonly, drunk is defined as your Blood Alcohol Concentration "BAC." This refers to a ratio of alcohol-to-blood.

Charts are often used to "show" this BAC, but it is seldom actually explained. For example, in California a BAC of .08% is considered to be a "drunk" rating. Expressed as an actual ratio, this means that you have 8/10 ths of a drop of alcohol, for every 1,000 drops of blood in your body!

This shows just how poisonous alcohol is! But, this is just a "measuring stick". Let's look at it a little closer.

The reality is that, being drunk means that you have overdosed on a poison! Your body, brain, and nervous system are now beginning to do a shut-down.

Because of its' effect on the "pleasure center" of the brain, you don't FEEL like you have overdosed... You feel happy, euphoric, and capable of things that you can't actually do -- like drive a car.

Legal limits are important for law enforcement, but Mother Nature doesn't needs police and judges. Violate her laws, such as taking too much of a poison, and her justice is swift, sure, and final.

0.05% BAC : Euphoric, relaxed and congenial.

0.07% BAC : Talkative, excited and sociable.

0.10% BAC : Uncoordinated, slurred speech and loss of inhibitions.

0.12% BAC : Unrestrained behavior, lack of control and loss of judgment.

0.20% BAC : Loss of alertness, drowsiness and lethargy.

0.30% BAC : Stupor or comatose state.

0.40% BAC : Suppression of respiratory function, erratic heartbeat-can be fatal.

0.50% BAC : Death is very likely to occur.
