How Long Does it Take for Alcohol to Kick In?

How long does it take for alcohol to kick in

Alcohol doesn’t kick in instantly. But it can kick in fast, depending on how your body handles it. 

Many factors affect the way your body processes alcohol. They include factors you can’t change, such as your medical conditions and gender. They also include factors like how long it’s been since you’ve eaten food, or whether you’re using other substances. 

It also depends on what you’re drinking. Some alcoholic drinks are stronger than others. A can of beer isn’t the same as a shot of vodka, for instance. 

Here’s what you need to know about how your body handles alcohol: 

How fast can you feel the results of alcohol?

It can take 30 minutes for the average person to start feeling the effects of alcohol while drinking at a moderate pace. Alcohol can also take a different amount of time to kick in depending on what you’re drinking. It can also take more or less time for different individuals.

When you drink alcohol, it moves through your body into the stomach and small intestine. This is where your body absorbs the alcohol into your bloodstream.

When the alcohol reaches your bloodstream, you’ll begin to feel it kick in. You may feel: 

  • Euphoric
  • Less inhibited 
  • More social
  • Less coordinated
  • More tired or fatigued 

Alcohol Consumption: Male vs Female

Men and women metabolize alcohol differently. Women can get drunk faster than men and might feel the effects more. 

Women have more body fat and less water weight than men. Fat has trouble absorbing alcohol, while water absorbs it easily. 

That means more of the alcohol is absorbed by the bloodstream in women, while more of it is absorbed into the body’s water reserves in men. The bloodstream is where alcohol starts having an intoxicant effect. The quicker the alcohol reaches the bloodstream, the faster you’ll get drunk. 

Other reasons women might metabolize alcohol faster than men include: 

  • Hormone differences. High estrogen levels make the brain’s reward center more sensitive to alcohol. Women have more estrogen than men do, so they might feel the effects more quickly. 
  • Digestive enzyme differences. Women have lower levels of dehydrogenase than men. This is an enzyme that helps the body break down alcohol. The average woman has half the amount of this enzyme compared to men. This means it takes longer to move alcohol out of the bloodstream. Women may feel drunk longer than men. 
  • Height and weight differences. People who are larger take longer to metabolize the same amount of alcohol. Women are often shorter and weigh less than men, so they may feel drunk faster.  

More men drink alcohol than women do. But alcohol use disorder increased 83% in women between 2002 and 2013. The rise could be caused by gender differences. It’s easier to develop a problem when your body processes alcohol faster and holds onto it longer. 

Alcohol and Weight

People who weigh more might take longer to feel the alcohol kick in. That’s because people with more bodyweight have more blood plasma. The more blood plasma, the longer it takes for the blood alcohol concentration to rise. 

Alcohol and the Liver

No matter how much you weigh, your liver can still only process one standard drink per hour. What makes a drink “standard” depends on its alcohol content.

For instance, a standard drink could be: 

  • A 12-ounce beer
  • A 7-ounce glass of malt liquor 
  • A 4-ounce glass of wine
  • A 1.25-ounce shot of 80-proof liquor 

It’s best to avoid drinking more than one standard drink per hour. Any more than that taxes the liver. Drinking too much short-term can make you too intoxicated, too fast. It can even lead to alcohol poisoning. In the long-term, it can cause permanent liver damage. 

Alcohol and Tolerance

Your tolerance has an effect on how fast alcohol kicks in. The more often you drink alcohol, or the higher the amount, the less your body responds to it. You may need to drink more alcohol to feel the same effect. 

If you don’t drink alcohol very often, then you might feel drunk after fewer drinks than you expected. 

Genetic Alcohol Intolerance

Asians and Native Americans have less alcohol tolerance than other ethnicities. All people have an enzyme that helps break down alcohol, called acetaldehyde dehydrogenase. People of these two ethnicities have a genetic difference, so their enzymes don’t work as effectively. 

People with this genetic difference might get drunk faster and stay drunk longer. This is because alcohol stays in the bloodstream longer. 

If you have genetic alcohol intolerance, then you might notice a reaction when you drink. This feels like your cheeks flushing and your heart rate increasing. Your skin will also become pink. 

This can happen even when you’re drinking only a small amount. It’s harmless, but you might be too uncomfortable to keep drinking. 

Alcohol and Medications

Alcohol interacts with many substances, including prescription and over-the-counter drugs. 

Prescription and over-the-counter drugs that interact with alcohol include:

  • Allergy, cold and flu medications such as Benadryl, Sudafed, and Tylenol
  • Anxiety and depression drugs such as Ativan, Klonopin, Valium, and Paxil
  • Antibiotics such as Flagyl and Zithromax 
  • Antipsychotic drugs such as Seroquel and Risperdal
  • Diabetes drugs such as Glucotrol and Orinase
  • Heartburn and indigestion medications such as Reglan and Zantac 
  • Pain medications such as Celebrex and Naprosyn
  • Sleep medications such as Ambien, Lunesta, and Unisom 

These are just a few kinds of drugs that interact with alcohol. There are hundreds more. Always check with your doctor about alcohol interactions before taking a new drug. Nearly half of prescription and over-the-counter drugs interact with alcohol. 

A drug interaction can be uncomfortable, with symptoms such as dizziness and nausea. Or it can be life-threatening, with changes in blood pressure and breathing. Mixing alcohol with other drugs often increases the risk of overdose, too. Always get medical help if you’re having a drug interaction with alcohol.  

Alcohol and Drugs

Street drugs can interact with alcohol. Some drugs that interact with alcohol include: 

  • Cocaine
  • Heroin
  • Kratom
  • MDMA
  • Molly
  • Mushrooms

Mixing alcohol with drugs can intensify the effect of both substances. But it can also be deadly: Overdoses happen more often when you mix substances. 

The riskiest interactions are with opioids and cocaine. Heroin and other opioid drugs slow breathing, and breathing can stop completely when these drugs are mixed with alcohol. 

Cocaine mixes with alcohol in the liver to create a new chemical. This chemical, cocaethylene, makes the cocaine’s effects stronger, but also puts you at risk for sudden death. 

Never mix alcohol with street drugs. If you think you’re having a drug-alcohol interaction, get medical help right away. 

How Long Does Alcohol Take to Kick in on an Empty Stomach?

Alcohol is absorbed mostly through your stomach and small intestine. That means it kicks in faster when you haven’t eaten recently. You might feel the effects more intensely. 

On the other hand, if you’ve eaten a big meal, it might take longer to kick in.  

That doesn’t mean you should avoid eating so you can get drunk faster. In fact, you should plan to eat an hour before drinking. Eating on an empty stomach can worsen hangover symptoms, causing:

  • Dehydration
  • Mood changes
  • Migraines
  • Nausea and vomiting
  • Trouble thinking
  • Vertigo

If you drink on an empty stomach and have these symptoms, you can treat them by resting, drinking enough fluids, and eating light foods like crackers. 

The Risks of Drinking on an Empty Stomach

There are serious health consequences to drinking on an empty stomach. You could develop alcohol poisoning, which can cause brain damage and coma. It can even be fatal. 

The symptoms can include: 

  • Mental changes
  • Slow breathing
  • Trouble speaking or moving
  • Losing consciousness

If someone you’re drinking with develops these symptoms, get medical help right away. Alcohol poisoning can be fatal and causes permanent damage.

Don’t drink on an empty stomach. It might be tempting to feel the effects faster, but it’s not worth the side effects. Always make sure you eat within an hour before moderate drinking. You should snack while you’re drinking if you drink for long periods. 

How Long Does it Take for Alcohol to Affect the Brain?

Alcohol affects the brain by causing cognitive problems. This impairment causes signs you associate with being drunk, including: 

  • Slurred speech
  • The trouble with motor skills, e.g. walking and fine motor
  • Slow reaction times
  • Trouble thinking or concentrating
  • Memory problems, including blacking out

It has this effect on your brain because it depresses the central nervous system. When the CNS is depressed, your brain has trouble communicating with the rest of your body. Signals between the brain and the body are slowed. The more you drink, the stronger the effect. 

It takes about 30 minutes to an hour for alcohol to affect the brain. This is how long it takes for alcohol to move from your stomach and small intestine to the bloodstream. The bloodstream moves alcohol throughout your body, including the brain.  

Does Alcohol Affect the Brain Permanently?

Alcohol can cause permanent brain damage if you drink too much of it. It damages the white matter fibers that connect different parts of the brain. This means your brain has a harder time communicating with itself. This can cause long-term, permanent brain damage. 

Sometimes the brain damage caused by alcohol leads to dementia. When this happens, it’s called Korsakoff syndrome. 

Korsakoff syndrome happens when alcohol prevents your body from getting enough thiamine. This causes your brain cells to have trouble carrying signals. 

The signs include: 

  • Trouble learning new information
  • Long gaps in your memory
  • The trouble with short-term memory
  • Making up false explanations to fill in memory gaps 
  • Hallucinating 

Treatment includes abstaining from alcohol and eating well. Thiamine supplements may help some people. 

The syndrome can be permanent. Around 25% of people with Korsakoff syndrome recover when they stop drinking alcohol. 50% of people improve but don’t recover completely, and another 25% never see a change in their symptoms. 

If you have had Korsakoff syndrome, your ability to metabolize alcohol is damaged. That means you have a lower tolerance. You’re also at higher risk for health problems when you drink. Avoid drinking alcohol if you have Korsakoff syndrome. 

How Long Does it Take to Get Sober? 

Generally, your body can metabolize one standard drink per hour. If you drink one shot of liquor, the effects wear off after about an hour for most people. A pint of beer might take two hours, while a tall glass of wine could take three hours. If you’re drinking heavily over a short time period, then it could take even longer for it to wear off. 

The same factors that affect how fast alcohol kicks in affect how long it stays in your body, too. These can include: 

  • Age and gender
  • Bodyweight
  • Drugs or medications that you’re using
  • Whether you’re drinking on an empty stomach
  • How many drinks you’re having, and how fast

There are some steps you can take to help alcohol leave your body faster. They include: 

  • Limiting your drinking to one per hour
  • Eating food
  • Drinking water
  • Avoiding caffeine, which can increase intoxication 

The effects of alcohol can wear off fast, but traces stay in your body for much longer. Breathalyzer tests detect whether you’ve had alcohol in the last day. Urine tests can detect alcohol up to two days after drinking. Hair tests can detect alcohol up to three months later. 

Drink Responsibly

How your body handles alcohol depends on many factors. Some of them are in your control, but some aren’t. Drink responsibly by knowing how your body handles alcohol. Avoid binge drinking, since it can flood your system with more alcohol than it can process. 

Drinking moderately and safely can lower your risk of alcohol-related health problems. When you drink more than your body can handle, you put yourself at risk of alcohol poisoning and permanent brain damage.
