Alcohol intoxication can be harmful for a variety of reasons, including:

  • Impaired brain function resulting in poor judgment, reduced reaction time, loss of balance and motor skills, or slurred speech.
  • Dilation of blood vessels, causing a feeling of warmth but resulting in rapid loss of body heat.
  • Increased risk of certain cancers, stroke, and liver diseases (e.g., cirrhosis), particularly when excessive amounts of alcohol are consumed over extended periods of time.
  • Damage to a developing fetus if consumed by pregnant women.
  • Increased risk of motor-vehicle traffic crashes, violence, and other injuries.
Coma and death can occur if alcohol is consumed rapidly and in large amounts.

Alcohol affects every organ in the body. It is a central nervous system depressant that is rapidly absorbed from the stomach and small intestine into the bloodstream. Alcohol is metabolized in the liver by enzymes. However, the liver can only metabolize a small amount of alcohol at a time, leaving the excess alcohol to circulate throughout the body. The intensity of the effect of alcohol on the body is directly related to the amount consumed.

Alcohol is known as Ethyl alcohol or Ethanol. It is an intoxicating ingredient found in beer, wine, and liquor. Alcohol is produced by the fermentation of yeast, sugars and starches.
