Alcohol Abuse and Dependence-What Happens

    Alcohol abuse or dependence can develop very quickly or happen gradually over years. In the beginning, your drinking might not seem to be any different from the way other people drink. You may drink only with friends or at parties. It may stay like this, or you may begin to drink more. Your drinking might become a way for you to feel normal or to cope with life's problems.

Blood Alcohol

    A blood alcohol test measures the amount of alcohol (ethanol) in your body. Alcohol is quickly absorbed into the blood and can be measured within minutes of having an alcoholic drink. The amount of alcohol in the blood reaches its highest level about an hour after drinking. But food in the stomach may increase the amount of time it takes for the blood alcohol to reach its highest level. About 90% of alcohol is broken down in the liver camera.gif. The rest of it is passed out of the body in urine and your exhaled breath.

Self-Test for Breath Alcohol

A breath alcohol test is an estimate of your blood alcohol concentration (BAC). The test measures the amount of alcohol in the air that you breathe out (exhale).
