For more information about alcohol metabolism, check out our alcohol metabolism page. A person should consider getting a ride home if they intend to drink two or more drinks. You likely have no comprehension of where you are or what you are doing. There have been numerous cases of alcohol poisoning and death in this range of BAC. Vomiting is likely and the chance of asphyxiation on your own vomit is greatly increased.
That generous glass of wine may actually be considered two drinks. It can take anywhere from 2 to 4 drinks within the hour to reach a 0.08% BAC.

Dangers of High BAC Levels
Use our calculator to estimate, but don’t forget that everyone metabolizes alcohol (beer, wine, liquor) differently. Our calculator can give you an approximate BAC level, but do not rely upon it to determine if you’re fit to drive or work. Blood alcohol content calculators use mathematical formulas to estimate BAC levels based on input variables such as the number of drinks consumed, body weight, and time since drinking.
What is the legal blood alcohol level?
While these calculators provide approximate BAC levels, actual BAC can vary based on individual differences in alcohol metabolism and other factors. Blood alcohol content (BAC) shows how much alcohol is in your blood after drinking alcohol. Alternative expressions for measuring alcohol levels in your system include blood ethanol concentration and blood alcohol level.
Blood Alcohol Concentration (BAC)
This article reviews what blood alcohol content is and why it is important. It also includes charts showing different blood alcohol levels based on sex, weight, and number of drinks. A blood alcohol test measures the amount of alcohol (ethanol) in your body. Alcohol is quickly absorbed into the blood and can be measured within minutes of having an alcoholic drink.
A blood alcohol test is often used to find out whether you are legally drunk or intoxicated. If this test is being done for legal reasons, a consent form may be required, but refusing to take the test may have legal consequences. Experts recommend educating people on the signs of alcohol intoxication and factors that affect BAC levels for accurate monitoring. No accurate BAC calculators exist for the public; only rough tools can estimate your blood alcohol level.
If you haven’t passed out, the risk of personal injury is high because you have little to no physical control. You may begin feeling tired because the depressant qualities of alcohol begin to take effect. (If you are a man, you will have difficulty achieving or maintaining an erection.) You will have trouble walking or standing and are at a greater risk of hurting yourself physically. If alcohol is found in your blood, the BAC can range from very little, such as a BAC of 0.02, to a BAC of more than 0.50. Reach out to talk with one of our compassionate treatment specialists. Some online platforms and apps have tools to help you estimate your BAC, but they are not always accurate.
A provider then sends the samples to a lab where a medical laboratory scientist prepares the samples and performs the tests on machines known as analyzers. Knowing what a standard drink is and keeping track of how long you’ve been drinking can help you drive safely. This means you can probably drive safely after having just one drink.
In moderation, alcohol can be OK for people old enough to legally drink. However, if you drink excessive amounts of alcohol in a short amount of time and/or drink large amounts frequently, your health can be at risk. If you’re concerned about your drinking habits, reach out to your healthcare provider or a specialist.

Past this point, a person will continue to experience worsening symptoms and may pass out or even die from alcohol poisoning. In most states, the legal limit is .080 BAC, meaning anything over this number indicates a person is too intoxicated to drive. Blood tests are a very common and essential part of medical testing and screening.
BAC is the percentage of alcohol a person has in their bloodstream. The higher the percentage, the more intoxicated and impaired a person becomes. Most states set the legal limit of BAC at .08% for both males and females. Lower-weight people may reach that level after about two drinks, while heavier people may not reach the level until about four drinks.
What Factors Affect BAC?
Remember, you are never alone in this journey, and a healthier relationship with alcohol is within reach. Drinks that contain high levels of sugar (like fruit juice) will actually slow the rise in BAC. This is because sugar requires digestion, and that can delay the time it takes for alcohol to be absorbed from the stomach into the bloodstream. Oppositely, carbonated drinks will actually cause BAC to rise more rapidly because any type of carbonation speeds up absorption. People with higher levels of testosterone tend to have more muscle mass than people with high levels of estrogen. Since muscle contains more blood than fat, the alcohol will dilute more easily and cause BAC to remain lower.
Blood Alcohol Levels Explained
- Your report may provide blood alcohol level test results in different ways depending on the laboratory that processes the test.
- Blood alcohol concentration (BAC) is a measure of the amount of alcohol that is present the blood, based on the volume of alcohol consumed over a given period of time.
- Some women may even find that they get intoxicated faster the week before their periods due to hormonal changes.
- The results are typically reported in the percentage of blood alcohol content (BAC) — for example, 0.03% BAC.
Stopping alcohol use all of a sudden can lead to alcohol withdrawal syndrome, a potentially life-threatening condition. Our center provides on-site medical detox with 24/7 support for your safety and comfort during your stay. Many bars and restaurants serve drinks with “heavy pours,” giving you more alcohol than usual. This can make reaching a BAC above 0.08% easy with just one or two drinks. The Czech Republic, Colombia, and Vietnam all have zero-tolerance policies regarding drinking and driving, no matter your age.
But what exactly is BAC, and what do different BAC levels feel like? Below, find a simple blood alcohol content chart, symptoms of each blood alcohol level, and how to accurately test your BAC. The following are some common questions about blood alcohol levels. Your report may provide blood alcohol level test results in different ways depending on the laboratory that processes the test. The results are typically reported in the percentage of blood alcohol content (BAC) — for example, 0.03% BAC. That said, just because tolerance can affect the way someone feels after drinking, it does not affect their BAC.
If you are planning on drinking alcohol, it is important to understand blood alcohol level or blood alcohol content (BAC). It is crucial that you know what the numbers mean, because this knowledge can make a massive difference if you are drinking and driving. Such knowledge can help gauge how alcohol might affect them personally and inform safer drinking practices.
If you have questions or concerns about your results, talk to your healthcare provider and/or a lawyer, depending on your situation. Blood alcohol concentration (BAC) is a measurement of how much alcohol you have in your body. This can be used to determine when someone is legally intoxicated (drunk). The grams of alcohol per 100 milliliters of blood determine blood alcohol content. If you’re going to drink, it’s essential to bac depends on what know the legal limits before that first sip and what constitutes drunk driving for law enforcement.
