Disclaimer

This is not intended as a scientific tool for measuring Blood Alcohol Concentration (BAC), but is rather designed to help adults of legal drinking age understand the factors that affect their BAC. The information presented should not take the place of your own responsible decisions about drinking alcohol, or about whether and when it will be safe for you to drive. The effects of alcohol vary among individuals because of many factors and may be different for the same person at different times. The BACs shown are solely for illustrative purposes, and do not reflect the interaction of alcohol with prescription, over-the-counter, or illegal drugs. Mixing any drug with alcohol can be dangerous to you and to others. 21 is the legal drinking age in the United States.

The Virtual Bar is a model that is designed to simulate how alcohol is normally processed in the body. The Virtual Bar is based on data obtained from controlled clinical trial studies of human participants who ate a pre-determined, portion-controlled meal, waited 15 minutes, and then consumed controlled portions of alcoholic beverages for 30 minutes until they reached a peak BAC of 0.10. In the no-food condition used as a control, participants consumed the alcohol in 30 minutes without prior food intake. Like all experimental models, the Virtual Bar model contemplates that individuals will experience some deviations from the original data; however, the closer the individual user's experience aligns to the underlying study data the more reliable will be the estimates in the Virtual Bar.

Food

The absorption of alcohol is inversely affected by how much food there is in the stomach. When the stomach is full, that is when the largest impact on slowing and moderating the effects of alcohol absorption is likely to occur. As the stomach empties, the effects of food on peak BAC would diminish; however, the Virtual Bar does not account for gastric emptying, so each additional drink is treated the same – hypothesized at 15 minutes at the end of the meal.

As a rule of thumb, the stomach takes about four hours to empty after a meal.

Your Peak BAC

0.000

 

You feel a little warm and relaxed. You’re experiencing slight euphoria and loss of shyness, but no loss of coordination.

You are feeling relaxed, talkative, and mildly euphoric. Your inhibitions are lowered and your reasoning and memory are impaired slightly. Your coordination may be mildly impaired.

Your balance might be off, and your speech slurred. Your judgment and self-control will be reduced, and your reasoning, ability to assess risk, and memory may be impaired. At .08 it is illegal to drive in all 50 states and DC.

You believe you are functioning better than you are. You are noisy and may engage in possibly embarrassing behaviors. There is a noticeable reduction in your reaction time. At .08 it is illegal to drive in all 50 states and DC.

You should be very clumsy and clearly drunk at this point. Your judgment and memory are getting worse, as well as vision, reaction time, and hearing. At .08 it is illegal to drive in all 50 states and DC.

You’re in ‘blackout’ territory. It’s very likely that you could have large gaps of memory missing the next morning. Drivers with BAC of .15 or more are responsible for more than half of the alcohol-related traffic fatalities in the United States. At .08 it is illegal to drive in all 50 states and DC.

You should’ve hit the brakes a long time ago. You are sloppy drunk and will need assistance walking. Your inability to keep your hands steady might cause you to spill it if you have another drink. You’re in danger of passing out, and should have severe nausea at this point, as your body is trying to expel the alcohol. You could conceivably die from choking on your vomit. At .08 it is illegal to drive in all 50 states and DC.

May experience extreme impairment, including total mental confusion, nausea and vomiting, difficulty walking, etc.

You may pass out or experience a loss of consciousness. You could die of alcohol poisoning. Consuming this much alcohol is dangerous and possibly life-threatening. At .08 it is illegal to drive in all 50 states and DC.

If you have not already lost consciousness, drinking to this level may result in coma, or even worse, death. At .08 it is illegal to drive in all 50 states and DC.

Lower levels might kill you, but a .40 stands a much greater chance. You could easily lapse into a coma or die due to respiratory arrest. Death occurs in at least half the drinkers who reach this BAC. At .08 it is illegal to drive in all 50 states and DC.

You are likely unconscious or even in a coma, as this is the level of surgical anesthesia. At a BAC of 0.45 or higher death will occur in most people.

At this consumption level it will take more than 24 hour to return to a .00 BAC level; serious health effects are possible.
