Alcohol is a depressant, which means it slows the function of the central nervous system. Alcohol actually blocks some of the messages trying to get to the brain. This alters a person's perceptions, emotions, movement, vision, and hearing.In very small amounts, alcohol can help a person feel more relaxed or less anxious. More alcohol causes greater changes in the brain, resulting in intoxication.

Although most individuals who drink alcohol do so safely, many people are unaware of the negative effects -- and some possible benefits -- alcohol can have on health. Between 20% - 40% of hospital admissions are alcohol related nationwide.
