Alcohol is a depressant. It slows down some brain functions. Its effect varies from one person to the next. In some it causes increased anxiety, in others it reduces tensions and worries and increases appetite. The person becomes more carefree as alcohol takes away inhibition. A person's self control is reduced. People tend to take personal and social liberties they may regret when the effect of alcohol has worn out.

As a person takes in more alcohol more obvious effects of intoxication occur. These include slurred speech, blurred vision, and poor muscle coordination. It is often seen that after drinking too much a person becomes clumsy and unable to walk steadily.

As a drinker continues to have more alcohol, he or she enters into a state called the drunken stupor. This state results are more area of the brain is dulled. Eventually, the brain is anaesthetized, unconsciousness occurs. High levels of alcohol (0.7%) in the blood may paralyse the medulla oblongata of the brain. This part controls the breathing and heart beat of a person. Death results if this part of the brain is paralysed. It is estimated that extreme intoxication takes about 100 lives in the United States per year.
