Understanding Blood Alcohol Content

The total ratio of alcohol to blood volume is known as blood alcohol content (BAC)

Blood alcohol content is typically expressed as a percentage. Many factors influence BAC including:

  • How fast you consume the alcoholic drinks
  • Amount of drinks consumed
  • Body weight
  • Gender
  • Body type
  • If there is food in your stomach
  • Medications you take


    Standard Drink Sizes

    Different drinks come in different sizes, but contain roughly the same amount of alcohol.

    It’s important to understand what a standard drink size is so that you can accurately track how much you are consuming. A standard drink contains about 14 grams of pure alcohol. That same amount can be found equally in a regular beer (12fl oz – 5% alcohol), malt liquor (8-9fl oz – 7% alcohol), table wine (5fl oz – 12% alcohol), and a cocktail (1.5fl oz – 40% alcohol).

    Blood Alcohol Levels & Effects

    BAC Levels

    • 0.0-0.05 – You will start to feel the effects of drinking, sleepiness can begin, you might feel relaxed, mild speech, memory, attention and coordination deficits begin to occur.
    • 0.06-0.15 – Relaxation gives way to increasing intoxication. Some people may become aggressive or confused. Speech, memory, attention, balance and coordination are further impaired. There is a significant impairment of driving skills at this point. You are now at risk of injuring yourself and others.
    • 0.16-0.30 – All driving related skills are dangerously impaired. Judgement and decision making are impaired. Vomiting and other signs of alcohol poisoning may begin. Speech, memory, attention, balance, and coordination are now significantly impaired.
    • 0.31-0.45 – Loss of conciousness. Life threatening alcohol poisoning. Risk of death.

    Alcohol Poisoning

    Alcohol poisoning happens when you drink a large amount of alcohol in a short amount of time. This results in a toxic amount of alcohol in the body that leads to a high BAC. This can be a life-threatening situation as a person with alcohol poisoning can stop breathing. If you suspect someone has alcohol poisoning you should contact emergency medical services immediately.

    Colorado Laws & DUIs

    In the case of alcohol, the legal limit for an adult in Colorado is usually determined to be .08 percent (or higher) blood alcohol content (BAC). While the easiest answer is to never drive over the legal limit if you or a loved one has been charged with a DUI, it’s important to act fast and consult with an experienced DUI attorney as soon as possible.
