Here's a longish but useful overview of physical blood-alcohol issues. See link for a longer presentation:
http://chavesdwiprogram.us/pdf/Effects% ... cation.pdfFactors that will affect the BAC in a person:•
How much alcohol you drink.
•
How fast you drink. The quicker you drink, the higher your peak BAC will be. The liver
gets rid of alcohol at the average rate of one drink per hour (12 oz. beer, 5 oz. wine, 1
shot of distilled liquor). If a person drinks faster than this, the remainder will circulate in
the blood stream until the liver can get rid of it.
•
Body weight. Heavier people will be less affected by the same amount of alcohol than
lighter people. They have more blood and water in their bodies in which to dilute the
alcohol.
•
Food in the stomach. When there is food in the stomach, alcohol is absorbed slower into
the blood stream. The BAC rises more rapidly in those who drink on an empty stomach,
because there is no food to slow the speed the alcohol is absorbed into the blood.
•
The type of alcohol you drink. The stronger a drink is (the higher the alcohol
concentration, distilled alcohol first, wine second, beer third) the more quickly it is
absorbed. This partially explains why hard liquor has more of an apparent “kick” than
wine or beer.
•
Type of mixer used. Water and fruit juices mixed with alcohol slow the absorption
process, while carbonated beverages will speed it up. Carbon dioxide speeds the alcohol
through the stomach and intestine into the bloodstream, creating a rapid rise in BAC.
•
Temperature of the drink. Warm alcohol is absorbed quicker than cold alcohol.
•
If you are male or female. Women reach higher BAC’s faster because they have less
water in their bodies and more adipose tissue (fat), which is not easily penetrated by
alcohol. Therefore, a man and woman, with all other factors being equal, both drinking
the same amount of alcohol will have different BAC levels. Hers will be higher. A
woman’s menstrual cycle will also affect her rate of absorption. They will experience their
highest BAC’s pre-menstrually. In addition, there is also evidence that a woman taking
birth control pills, will absorb alcohol faster, resulting in higher BAC levels.
