How much vodka does it take to get drunk?

Vodka is one of the most popular distilled spirits in the world, known for its lack of aroma and flavor. Many people enjoy vodka in cocktails or mixed drinks, while others prefer to drink it straight or “neat.” However, vodka contains a high alcohol content, typically 40% alcohol by volume (80 proof). This leads many to wonder, just how much vodka does it take to get drunk?

The answer depends on a variety of factors, including an individual’s body weight, gender, tolerance level, what they’ve eaten, and how fast they are drinking. While there are general guidelines based on these criteria, intoxication levels can vary greatly from person to person. This article dives into the details around vodka and intoxication.

What Determines Intoxication from Vodka?

There are a few key factors that play a major role in how intoxicated someone gets from drinking vodka:

Body Weight

Body weight is one of the biggest determinants of alcohol tolerance. Someone who is larger and heavier will require more alcohol to reach the same level of intoxication as someone much smaller. This is because alcohol distributes throughout the water in the body, and a heavier person has more fluid volume. Generally speaking, the more someone weighs, the more vodka it takes to get them drunk.


Gender plays a role because, on average, men have more muscle mass and women have more body fat. Muscle has a higher water content than fat, so alcohol distributes into more fluid in a typical male versus female. For this reason, it typically takes less vodka for women to become intoxicated compared to men of an equal weight.

Tolerance Level

Someone’s tolerance also greatly impacts intoxication level. Regular moderate drinkers build up more of tolerance over time. The liver creates additional enzymes to help metabolize and break down alcohol. For habitual drinkers, it will take higher volumes to achieve inebriation. On the other hand, occasional drinkers or those new to drinking often have low tolerances.

Stomach Contents

Drinking vodka on an empty stomach leads to faster absorption into the bloodstream and quicker intoxication. Eating a full meal before drinking slows down the rate of absorption. Higher fat and protein foods like cheese, meat, and nuts take longest to digest. Carbohydrates digest more rapidly, while light foods like vegetables and fruits digest quickest.

Hydration Status

Alcohol causes fluid loss from increased urination. If someone is already dehydrated before drinking, it can accelerate the effects of alcohol intoxication. Being well hydrated can help offset some of the effects of alcohol.

Rate of Drinking

The pace at which someone consumes vodka also changes how they feel the effects. Vodka shots or drinks consumed quickly raise blood alcohol content faster. Slow steady drinking over a longer time allows the liver more time to metabolize the alcohol. Having vodka mixed into a cocktail or served over ice slows down the pace of consumption versus taking straight shots.

Standard Drink Sizes

In order to estimate how much vodka leads to intoxication, it’s important to understand standard drink sizes. A standard drink equals 0.6 oz of pure ethanol alcohol. Different types of alcoholic beverages contain different amounts of pure alcohol:

  • Beer – 12 ounces at 5% alcohol = 0.6 ounces ethanol
  • Wine – 5 ounces at 12% alcohol = 0.6 ounces ethanol
  • Vodka – 1.5 ounces of 40% alcohol = 0.6 ounces ethanol

So while sizes and alcohol percentages vary across different drink types, each standard drink equates to the same 0.6 ounces of ethanol alcohol. This allows for easier comparisons of different alcoholic beverages impacts on intoxication levels.

BAC Levels by Number of Drinks

Blood alcohol content (BAC) refers to the percent concentration of alcohol in the bloodstream. This directly correlates to observable intoxication levels:

BAC Percentage Intoxication Level
0.02% – 0.03% Mild mood and behavior alterations, possible minor impairment in reasoning and memory
0.04% – 0.06% Relaxation, sensation of warmth, lowered inhibitions, minor impairment in reasoning and memory
0.07% – 0.09% Impaired coordination, balance, speech, reaction time, and hearing. Euphoria.
0.10% – 0.12% Significant impairment in motor coordination and loss of good judgment. Speech may be slurred. Balance, vision, reaction time, and hearing will be impaired.
0.13% – 0.15% Gross motor impairment and lack of physical control. Blurred vision and major loss of balance. Euphoria reduces and dysphoria increases showing as personality changes and mood swings.
0.16% – 0.20% Dysphoria predominates, nausea may appear. The drinker has the appearance of a “sloppy drunk.”
0.25% + Needs assistance in walking; total mental confusion. Dysphoria with nausea and some vomiting as common. Loss of consciousness.

In order to reach these BAC percentages, different numbers of drinks must be consumed depending on the person:

Gender Body Weight Number of Drinks to Reach 0.08% BAC
Male 140 lbs 3-4 drinks
Male 180 lbs 4-5 drinks
Female 120 lbs 2-3 drinks
Female 140 lbs 3-4 drinks

This accounts for the average differences between males and females. But there can be high individual variability around these estimates based on other factors like tolerance levels and stomach contents.

Typical Number of Drinks to Reach Inebriation

Now that we’ve looked at differences by gender and weight when it comes to intoxication, we can estimate how many vodka drinks it takes on average to reach drunk levels:

  • For a 120-130 lb female: 3-4 drinks
  • For a 140-150 lb female: 4-5 drinks
  • For a 140-150 lb male: 5-6 drinks
  • For a 180-200 lb male: 6-7 drinks

Consuming drinks faster than one per hour can more rapidly increase BAC levels. Alternating vodka drinks with water can help slow increases in inebriation. Many experts consider BAC levels of 0.08% and above associated with the legal definition of intoxicated. But even at lower BAC levels like 0.05%, motor coordination and reaction time start becoming impaired.

Volume in Ounces

Translating the number of drinks into fluid ounces of vodka:

  • For a 120-130 lb female: 4-6 oz vodka
  • For a 140-150 lb female: 6-7.5 oz vodka
  • For a 140-150 lb male: 7.5-9 oz vodka
  • For a 180-200 lb male: 9-10.5 oz vodka

This gives a rough guideline of the range in vodka volume needed to reach intoxicated levels. Factors like tolerance can allow some individuals to consume more, while an empty stomach may require less volume to see the effects of inebriation.

Timeline of Effects

After consuming the amount of vodka above to reach intoxication, here is a general timeline of how effects set in:

  • Within 5 minutes – Initial absorption into the bloodstream begins
  • 15-30 minutes – Effects start to become noticeable
  • 1 hour – Peak blood alcohol concentration is reached
  • 2-3 hours – BAC starts to decrease as alcohol is metabolized by the liver
  • 5-8 hours – Alcohol completely eliminated from the body in most people

It takes about 6 hours for the body to fully metabolize and remove one serving of alcohol. So the more that is consumed, the longer it takes to sober up.

Impact on Hangovers

While binge drinking leads to rapid intoxication, it also increases the odds of a unpleasant hangover. Consuming a high volume of alcohol over a short period allows for larger spikes in BAC levels. This triggers an inflammatory immune system response.

Hangovers symptoms like headache, nausea, fatigue, dizziness, sensitivity to light and sound, and stomach pain stem from the inflammation. Dehydration from alcohol’s diuretic effects also worsen hangover experiences.

To lower chances of a hangover, it’s recommended to:

  • Drink slowly over a longer period rather than taking rapid shots
  • Alternate vodka drinks with water to stay hydrated
  • Eat a meal before or while drinking to slow absorption
  • Avoid drinking to the point of severe intoxication

Health Risks from Excess Alcohol

While occasional moderate alcohol use may pose little health risk, frequent binge drinking and intoxication creates both short and long term dangers:

Short Term

  • Injuries from impaired motor skills, balance, and coordination
  • Riskier sexual behavior leading to unintended pregnancy or sexually transmitted diseases
  • Getting in fights or disputes
  • Drinking and driving accidents
  • Falls, burns, and other household accidents
  • Alcohol poisoning – an extreme BAC level that can lead to loss of consciousness or even death

Binge drinkers are at highest risk of these short term consequences. But even those who only periodically drink to intoxication levels can encounter these issues.

Long Term

  • Increased risk of liver disease like fatty liver, cirrhosis, and liver failure
  • Digestive problems like ulcers, acid reflux, and gastritis
  • Cardiovascular disease and stroke
  • High blood pressure
  • Pancreatitis
  • Various cancers including liver, colorectal, breast, prostate, and esophageal
  • Weakened immune system
  • Brain damage that impairs cognition, motor skills, and mental health
  • Alcoholism involving physical dependence and addiction

These long term health consequences illustrate why ongoing heavy alcohol use should be avoided whenever possible. People who drink moderately – 2 drinks or less per day for men and 1 drink or less per day for women – have lower risk of these detrimental effects over time.

Tips for Drinking Vodka Sensibly

Here are some tips for enjoying vodka without ending up dangerously intoxicated:

  • Pace yourself – no more than 1 drink per hour
  • Alternate vodka with water or other non-alcoholic drinks
  • Eat a meal before and while drinking
  • Keep track of the number of drinks you’ve consumed
  • Set a firm limit on drinks and don’t go over it
  • Avoid shots and drinking games that encourage excessive drinking
  • Have a sober designated driver or alternate transportation plan
  • Stay hydrated before going to bed to lessen hangover severity
  • Avoid drinking to cope with stress, anxiety, or depression

Knowing Your Own Limits

The most accurate way to determine your personal alcohol limits is to carefully test and track your response. Because there are so many individual variables involved, use the estimates in this article as a rough guide. But closely monitor your own intoxication level across a range of drink amounts.

Pay attention to differences depending on food intake, hydration levels, pace of drinking, etc. Knowing your unique point of inebriation will allow you to enjoy vodka drinks safely without overdoing it. Everyone has a different sweet spot between desired relaxation and loss of control.


How much vodka does it take to get drunk ultimately depends on your gender, weight, tolerance level, and other individual factors. Consuming around 2-3 standard size drinks in one hour will lead the average woman to intoxication, while it takes 3-4 drinks for the average man. This equates to roughly 4-9 ounces of vodka.

Drinking to the point of legal intoxication of 0.08% BAC or above comes with many health and safety risks both short and long term. Understanding your personal tolerance level provides guidance on drinking vodka sensibly for enjoyment while avoiding unwanted drunkenness. Moderation, pacing yourself, and other safe drinking practices are key. Knowing what vodka amounts cause you to cross the line into excessive intoxication allows you to drink responsibly within your limits.
