Absorption
Alcohol is absorbed from all parts of the gastrointestinal tract largely by simple diffusion into the blood. However the small intestine is by far the most efficient region of the gastrointestinal tract for alcohol absorption because of its very large surface area. In a fasting individual, it is generally agreed that 10% to 20% of a dose of alcohol is absorbed from the stomach (the volume of alcohol affects the absorption) and 75% to 80% is absorbed from the small intestine. Because of this peak blood alcohol concentrations are achieved in fasting people within 0.5 to 2.0 hours, (average 0.75 - 1.35 hours depending upon dose and time of last meal) while non-fasting people exhibit peak alcohol concentrations within 1.0, and in extreme cases up to as much as 4.0 hours (average 1.06 - 2.12 hours).
Because it is distributed so quickly and thoroughly the alcohol can affect the central nervous system even in small concentrations. In low concentrations, alcohol reduces inhibitions. As blood alcohol concentration increases, a person 's response to stimuli decreases markedly, speech becomes slurred, and he or she becomes unsteady and has trouble walking. With very high concentrations - greater than 0.35 grams/100 milliliters of blood (equivalent to 0.35 grams/210 liters of breath ) - a person can become comatose and die. The American Medical Association has defined the blood alcohol concentration level of impairment for all people to be 0.04 grams/100 milliliters of blood (equivalent to .04 grams/210 liters of breath). The following is a generally accepted guide to the effects of alcohol.
Distribution
Alcohol has a high affinity for water and is therefore found in body tissues and fluids inasmuch as
