Alcohol: What is a drink ?

The concentration of hard liquor is measured in proof to determine the concentration, divide the proof by two.

Blood Alcohol Concentration

  • A BAC of 0.10% is equal to one-tenth of one percent of a person's blood is alcohol.
  • BAC is measured by breath, blood or urine test.
  • If you refuse to submit to a chemical test to determine your BAC, your driver license will be taken away for one year.

Alcohol: Absorption

As alcohol enters the body, it passes from the mouth, down the esophagus, into the stomach and on to the small intestine.

Absorption Rate Factors

  • Food
  • Carbonated
  • Note

Alcohol: Distribution

Absorbed alcohol is rapidly carried throughout the body in the blood with approximately the same concentration. The concentration may vary in different organs, including the brain.

Distribution Factors

  • Body Fat
  • Body weight
  • Body type
  • These three factors all contribute to typical differences between males and females.

Alcohol: Elimination

The liver is responsible for the elimination of alcohol. The liver estimates 95% of ingested alcohol from the body through oxidation. On Average, a person will eliminate 0.5 ounces of alcohol (nearly one standard drink) per hour.

Elimination Factors

  • Rate of consumption (amount + Time)
  • Metabolic Tolerance
  • Functional Tolerance

Other factors related to Impairment

  • Expectations
  • Medications / Other Drugs
  • Fatigue
  • Mood
  • Tiredness
  • Illness

Alcohol and the Brain

The first portion of the brain to be affected is the cerebrum which is responsible for controlling the senses, speech, understanding, and judgement. Drinkers often feel the manual skills have been improved due to an impairment in judgement, when in reality their reaction times are slowed and their muscle coordination is less efficient. If a person continues to drink, the body protects it self from farther damage by falling asleep or passing out.

The Developing Brain

The adolescent brain is designed to learn However, the characteristics that lend it to acquire information, adapt, and learn, also render it more vulnerable to the effects of alcohol on the brain. Alcohol damages neurons and alters developing parts of the adolescent brain still forming.

Abuse vs. Addiction

Abuse

  • Spending a considerable time to get, use, and recover from alcohol
  • Increased tolerance to the effects of alcohol

The irrefutable law of Alcohol(drugs)

If you put it in your body it will have an effect.

Having a BAC of 0.02-0.03%

Having a BAC of 0.04-0.06%

Having a BAC of 0.07-0.09%
