Physiological Effects
Short-term effects depend on a variety of variables including
  • Amount consumed
  • Hydration
  • Blood alcohol concentration (BAC)
  • Tolerance

Short-term effects:
(0.03%-0.12% BAC)
(0.09%-0.25% BAC)
(0.18%-0.3% BAC)
(0.25%-0.4% BAC)
(0,35%-0.5% BAC)
  • Improvement in mood
  • Increased self-confidence and courage
  • increased sociability
  • shortened attention span
  • flushed appearance
  • inhibited judgment
  • impaired fine muscle coordination
  • Sedation
  • Impaired memory or comprehension

  • Severe ataxia- defined
  • Consciousness, Unconsciousness
  • Anterograde amnesia-l
  • Vomiting
  • Respiratory depression (life-threatening)
  • Inability to control your bladder
  • Decreased heart rate
  • Death may occur due to aspiration of vomit while unconscious
  • Unconsciousness
  • Half of those with a BAC of higher than 0.4% die
Long Term Effects
  • Addiction
  • Permanently impaired nervous system
  • Alcoholic Liver Disease (see cirrhosis, due to alcohol abuse)
  • Fibrosis of liver (cirrhosis where liver cells are damaged and replaced with scar tissue)
  • Increased chance of heart failure
  • Increased chance of strokes
  • Pancreatitis (inflammation of the pancreas)
The legal blood alcohol concentration in most states of the US and many other countries is 0.08%.

After drinking, the concentration of alcohol in the blood increases as the alcohol is absorbed into the blood and gradually declines with time as shown below:
