Understanding Blood Alcohol Content

Blood Alcohol Content (BAC) is the concentration of alcohol in the blood and is typically expressed as a percentage.  For example, a BAC of 0.10% means there is one part alcohol for every 1,000 parts blood.   

Several factors can influence an individual’s BAC; including, but not limited to: 
  • Amount of alcohol consumed (see standard drink size below)
  • Duration/Speed of consumption
  • Body type/weight
  • Physiological differences between men and women 
  • If food is present in the stomach
  • If other medications are present in the body


Many people are surprised to learn what constitutes one drink of alcohol; otherwise known as standard drink size. If you choose to drink, it is important to know and follow the standard measurements of alcohol so you can set a limit and accurately track the amount of alcohol consumed.


Alcohol poisoning occurs when an individual consumes a large amount of alcohol typically in a short period of time. Excessive drinking can result in a toxic amount of alcohol in the body leading to a high BAC and a potentially life threatening situation.   If you suspect someone has alcohol poisoning, contact emergency medical services immediately. 

Alcohol poisoning is preventable!  If you choose to drink, follow The Gold Code.
