According to the Dietary Guidelines for Americans: 2020-2025, a standard drink is defined as 14 grams (or 0.6 ounces) of pure alcohol. The amount of alcohol in a drink depends on the type of alcohol and the serving size. For example, a 12-ounce beer, 5-ounce glass of wine, and 1.5-ounce shot of liquor all contain the same amount of alcohol.

However, the amount of alcohol it takes to get drunk varies from person to person. Factors such as body weight, gender, and tolerance level can affect how much alcohol a person can consume before feeling drunk. Therefore, it’s crucial to drink responsibly and know your limits to avoid the negative effects of excessive drinking.

Blood Alcohol Concentration (BAC)

Alcohol affects everyone differently, and the amount of alcohol it takes to get drunk varies from person to person. Blood Alcohol Concentration (BAC) is a commonly used measure of alcohol intoxication that indicates the amount of alcohol in a person’s bloodstream. It is typically expressed as a percentage of alcohol per volume of blood.

What is BAC?

BAC is a measure of the amount of alcohol in a person’s bloodstream. When a person consumes alcohol, it is absorbed into the bloodstream through the stomach and small intestine. The liver then metabolizes the alcohol, breaking it down into water and carbon dioxide. The alcohol that is not metabolized is eliminated from the body through urine, sweat, and breath.

How is BAC Measured?

BAC can be measured through a blood, breath, or urine test. The most common method of measuring BAC is through a breathalyzer test. A breathalyzer measures the amount of alcohol in a person’s breath, which is proportional to the amount of alcohol in their bloodstream. Blood tests are more accurate than breath tests, but they are more invasive and require a medical professional to draw blood from the person.

Factors that Affect BAC

Several factors can affect a person’s BAC, including:

  • Body weight and size
  • Gender
  • Age
  • Metabolism
  • Type and amount of alcohol consumed
  • Food consumed before or during drinking
  • Medications or other substances consumed

It is important to note that BAC is not the only factor that determines a person’s level of intoxication. Other factors, such as tolerance, can also affect a person’s ability to function normally while under the influence of alcohol.

Factors that Affect Alcohol Absorption

Several factors affect how alcohol is absorbed and metabolized in the body. Understanding these factors can help individuals make informed decisions about their alcohol consumption and avoid overconsumption. The three main factors that affect alcohol absorption are gender, body weight, and food intake.


Due to differences in alcohol metabolism, women typically have a higher blood alcohol concentration (BAC) than men after consuming the same amount of alcohol. This is because women have less water in their bodies than men, which means that alcohol is less diluted in their bloodstream. Additionally, women have lower levels of the enzyme alcohol dehydrogenase, which breaks down alcohol in the stomach. This means that more alcohol enters the bloodstream before it can be metabolized, leading to a higher BAC.

Body Weight

Body weight also plays a role in alcohol absorption. Generally, the more a person weighs, the more water they have in their body, which means that alcohol is more diluted in their bloodstream. As a result, it takes longer for alcohol to reach a high BAC in individuals with a higher body weight. However, it is important to note that body weight is just one factor and should not be used as a sole indicator of how much alcohol a person can safely consume.

Food Intake

Food intake can also affect alcohol absorption. Eating food, particularly fat, protein, and fiber, while drinking alcohol will slow absorption. This is because food slows down the rate at which alcohol enters the bloodstream, giving the body more time to metabolize it. On the other hand, drinking alcohol on an empty stomach can lead to a faster rise in BAC, as the alcohol is absorbed more quickly into the bloodstream.

How Much Alcohol Does it Take to Get Drunk?

Drinking alcohol can be a fun and social activity, but it’s important to know your limits to avoid dangerous situations. The amount of alcohol it takes to get drunk varies from person to person, and there are many factors that can influence how quickly someone becomes intoxicated.

Legal Limits

In most countries, there are legal limits for blood alcohol concentration (BAC) while driving. In the United States, the legal limit is 0.08% BAC, which is equivalent to about four standard drinks for men and three for women, consumed within two hours. It’s important to note that this is just a guideline and that impairment can occur at lower BAC levels.

Personal Limits

Personal limits for alcohol consumption can vary based on factors such as age, weight, gender, and overall health. Generally, men can tolerate more alcohol than women due to differences in body composition. As people age, their bodies may become less efficient at metabolizing alcohol, so they may become intoxicated more quickly. It’s important to know your personal limits and to never exceed them.

Factors that Affect Intoxication

There are many factors that can affect how quickly someone becomes intoxicated, including:

  • The amount of alcohol consumed
  • The speed at which it is consumed
  • The strength of the alcohol
  • Whether the person has eaten recently
  • The person’s overall health and tolerance for alcohol
  • Whether they are taking any medications or drugs

It’s important to be aware of these factors and to drink responsibly to avoid dangerous situations.

Risks of Drinking to Intoxication

Short-Term Risks

Drinking to intoxication can lead to a variety of short-term risks, including:

  • Slurred speech and impaired coordination
  • Reduced inhibitions and impaired decision-making
  • Memory problems and confusion
  • Increased risk of accidents and injuries
  • Alcohol poisoning, which can be life-threatening

It is important to note that the effects of alcohol can vary depending on a number of factors, including a person’s weight, gender, and tolerance level.

Long-Term Risks

Drinking to intoxication on a regular basis can also lead to a variety of long-term health risks, including:

  • Liver damage and cirrhosis
  • High blood pressure and heart disease
  • Stroke and other cardiovascular problems
  • Cancer of the liver, esophagus, throat, or mouth
  • Depression and anxiety
  • Alcoholism and addiction

It is important to note that the risks associated with drinking to intoxication can be mitigated by practicing safe drinking habits, such as drinking in moderation, avoiding binge drinking, and staying hydrated while drinking.

How to Stay Safe While Drinking

Drinking alcohol can be enjoyable, but it is important to stay safe while doing so. Below are some tips on how to stay safe while drinking:

Know Your Limits

It is important to know your limits when it comes to drinking. Everyone’s tolerance level is different, so it is important to understand how much alcohol your body can handle. The amount of alcohol it takes to get drunk varies from person to person and depends on factors such as weight, gender, and age. As a general rule, the Dietary Guidelines for Americans: 2020-2025 defines a standard drink as 14 grams (or 0.6 ounces) of pure alcohol. It is important to pace yourself and avoid drinking too much too quickly.

Alternate Drinks

Drinking water or non-alcoholic beverages in between alcoholic drinks can help you stay hydrated and reduce the amount of alcohol you consume. It is also a good idea to eat food while drinking. Eating can help slow the absorption of alcohol into your bloodstream.

Designated Driver

Having a designated driver is important if you plan on drinking. A designated driver is someone who agrees to abstain from alcohol for the evening and drive you and your friends home safely. If you cannot find a designated driver, consider taking a taxi or using a ride-sharing service to get home.


While the amount of alcohol it takes to get drunk varies based on several factors, it is important to remember that drinking in moderation is key to avoiding negative consequences. According to the 2015-2020 Dietary Guidelines for Americans, moderation is defined as up to one drink per day for females and up to two drinks per day for males.

It is also important to note that different types of alcohol have varying alcohol content, so it is important to be aware of what you are drinking and how much alcohol it contains. For example, a standard drink of beer may contain less alcohol than a standard drink of wine or liquor.

Factors such as gender, weight, size, genetics, and tolerance can also affect how much alcohol it takes to get drunk. It is important to know your limits and to always drink responsibly. Drinking too much alcohol can lead to negative consequences such as impaired judgement, decreased coordination, and even alcohol poisoning.

If you choose to drink alcohol, it is important to do so in a safe and responsible manner. This includes drinking in moderation, knowing your limits, and never drinking and driving. By following these guidelines, you can enjoy alcohol in a safe and responsible manner.
