  2. ALCOHOL IS A TOXIC SUBSTANCE • Ethyl alcohol or ethanol is the substance associated with beverages and intoxicating liquors • It acts to depress the functions of the central nervous system

  3. It has significant impact on the ability to see, especially at night. At .10 BAC people are unable to fuse the vision or each eye into a single image (double vision) and glare is bothersome

  4. Once absorbed into the blood it is, within seconds, distributed throughout the body water compartments in consistent concentrations • Most people will reach full absorption within 30 minutes of the last drink, but can be up to 90 minutes depending stomach contents

  5. Once in the blood it is continually circulated through the liver where 90% to 98% if the ETOH is removed by breaking it down into carbon dioxide and water

  6. THE LIVER WILL ONLY DIGEST ONE STANDARD DRINK PER HOUR—NO MATTER WHAT YOUR ADULT SIZE

  7. PER HOUR • ELIMINATION RATES • .015 AVERAGE • .030 ALCOHOLIC • .005 NON-DRINKER

  8. FACTORS • FOOD • STRENGTH OF DRINK • BODY WEIGHT/TYPE • More body fat…..higher BAC

  9. WOMEN • Less enzyme that breaks down ETOH • Hormones • Higher body fat

  10. RATE OF CONSUMPTION • MEDICATIONS • ILLNESS

  11. FATIGUE • ALCOHOL EXPECTANCY

  12. ETOH CONTENT/FLUID OZ • BEER 4% 12 OZ • WINE 11% 4 OZ • LIQUOR 30-50% 1-1.5 0Z

  13. WIDMARK EQUATION • BAC = fluid oz of beverage x % alcohol • __________________________ • body weight x 13.1

  14. Jack states he had four green beers (12 oz, 4%) • He weighs 155 lbs

  15. BAC = (48)(4) / (155)(13.1) = 0.095 • This DOES NOT include any burn off during the drinking period
