Blood Alcohol Chart

What Does Blood Alcohol Level Mean?

A night of partying can leave you intoxicated far longer that you would expect.
Click below to study the Hours to Sober Chart and individual BAL charts by sex and weight.

Alcohol's effects are roughly predictable from the amount of alcohol in the blood stream, assuming that no tolerance has developed. Below is a list indicating what effects alcohol typically has at several BAL's.

Note: These effects occur for people who have not developed a high tolerance for alcohol. For tolerant people, these effects may not occur until higher levels of intoxication. Heavy drinkers must therefore consume more alcohol to achieve the same effect as moderate drinks which costs more money and is harmful to the body.

Blood Alcohol Level Effects

Mild relaxation; slight loosening of inhibitions; slight loss of social discomfort; mild intensification of mood.

0.05 - 0.06

How to use the Blood Alcohol Chart
  • Find the chart for your gender and your weight.
    How many drinks did you have? How many hours did it take you to drink them?
  • Draw a line horizontally from the # of drinks. Draw a second line down vertically from the # of hours. The point where these two intersect is your intoxication level at the time you stopped drinking. This is your Blood Alcohol Level.
    Choose a "safer" drinking level: The areas shaded GREEN
    indicate a blood alcohol level (BAL) of .055%
or
  • This is a guideline for determining a "safer" drinking level. In other words, a person who drinks at or below the number of drinks shown in the GREEN shaded area will be less likely to have unwanted or unintended negative experiences as a result of his/her drinking. The YELLOW and RED shaded areas indicate a higher level of health risks and negative consequences.
