Everyone thinks they know how to get drunk. You walk into a bar, order a drink, and wait for the buzz. But there is a massive gap between what people assume happens and the actual physiological process occurring in your liver and bloodstream. It’s not just about the number of shots. It's about biology.
Alcohol is a drug. Specifically, it's ethanol. When you consume it, you aren't "digesting" it in the way you digest a sandwich. Instead, it’s being absorbed directly through the linings of your stomach and small intestine. It’s fast.
The Mechanics of How to Get Drunk Safely
Most people focus on the "how" without understanding the "how much." Blood Alcohol Concentration (BAC) is the only metric that matters here. If your BAC hits 0.08%, you’re legally intoxicated in most of the United States. But getting there isn't a linear path for everyone.

Biological sex plays a huge role. Research from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) shows that women typically have less body water than men of similar weight. Alcohol disperses in body water. Less water means a higher concentration of alcohol in the blood. Women also tend to have lower levels of alcohol dehydrogenase—the enzyme that breaks down booze—in their stomachs.
Weight matters too, but it’s mostly about body composition. Fat doesn't absorb alcohol. Muscle does. So, two people weighing 200 pounds will feel the effects differently if one is a bodybuilder and the other isn't.
Why the First Drink Hits Different
The rate of absorption is the "secret sauce." About 20% of alcohol passes through the stomach wall. The remaining 80% goes through the small intestine. This is why drinking on an empty stomach is the fastest way to get drunk, though often the most physically punishing. Without food to act as a buffer, the alcohol hits the small intestine almost immediately. This leads to a rapid spike in BAC that can overwhelm the liver's ability to process the toxin.
Carbonation changes the game. Ever wonder why Champagne feels like it goes to your head faster? It’s the bubbles. The CO2 increases the pressure in your stomach, which forces the alcohol through the pyloric valve into the small intestine faster. A study published in the journal Alcohol and Alcoholism confirmed that subjects drinking carbonated vodka reached peak BAC significantly faster than those drinking flat vodka.
The Liver’s Impossible Task
The liver is the workhorse. It processes about one standard drink per hour. That’s roughly 1.5 ounces of spirits, 5 ounces of wine, or 12 ounces of 5% beer. There is no way to speed this up. You can't sweat it out. You can't drink enough coffee to "wake up" your liver. You're just a wide-awake drunk person at that point.
When you consume more than one drink an hour, the excess alcohol circulates in your blood. It hits the brain. Specifically, it suppresses the central nervous system. It starts with the cerebral cortex, which handles judgment and inhibitions. That’s why you get chatty. Then it moves to the hippocampus (memory) and the cerebellum (movement).
Myths People Still Believe
You've heard it a million times: "Beer before liquor, never sicker." Science says it’s a lie. The order doesn't matter nearly as much as the total quantity of ethanol. The reason people get sick when they switch to liquor late in the night is usually because they are already intoxicated and have lost the judgment to pace their shots.
Congeners are another factor. These are chemical byproducts of fermentation. Dark liquors like whiskey and red wine have more of them than clear spirits like gin or vodka. While they don't necessarily make you "more drunk," they contribute heavily to the severity of the hangover the next day. A study at Brown University found that while participants reached the same level of intoxication on bourbon versus vodka, the bourbon drinkers reported much worse hangovers.
The Danger Zone: Understanding Tolerance
Tolerance is a sneaky thing. Functional tolerance happens when your brain adapts to the presence of alcohol. You might feel "sober," but your BAC is still high. This is where most accidents happen. You feel fine, so you drive. But your reaction times are still biologically impaired.
Then there’s metabolic tolerance. This is when the liver gets "better" at producing enzymes to break down the booze. It sounds like a superpower, but it's actually a sign of chronic consumption that can lead to liver disease.
Practical Realities of Consumption
If the goal is to experience the effects of alcohol without ending up in a hospital or with a two-day migraine, pacing is the only real strategy.
- Hydrate between rounds. Alcohol is a diuretic. It inhibits the antidiuretic hormone (ADH), which tells your kidneys to conserve water. This is why you pee so much when you drink. Replacing that water prevents the brain shrinkage (yes, literally) that causes hangover headaches.
- Eat proteins and fats. These slow down the emptying of the stomach. A steak or a burger before drinking is more effective than "sopping it up" with bread afterward.
- Know your ABV. Not all beers are created equal. A craft IPA at 9% ABV is almost double the strength of a standard lager. Treating them the same is a recipe for disaster.
The Psychological Component
Expectancy theory suggests that your environment and mindset dictate how you feel while drunk. If you're at a high-energy party, you'll likely feel a "stimulant" effect initially. If you're drinking alone on your couch, you’ll likely feel the "depressant" side of alcohol much sooner.
Alcohol triggers dopamine release in the reward center of the brain. This is the "feel good" part of the high. But it's fleeting. As your BAC begins to drop, the brain experiences a rebound effect, often leading to anxiety or "the shakes." This is the physiological "price" of the dopamine spike.
Real-World Risks and Legalities
Every year, thousands of people end up with alcohol poisoning because they don't understand the lag time. You can drink five shots in ten minutes, but it takes 30 to 60 minutes for that peak BAC to hit. People keep drinking because they "don't feel it yet," only to have the full force of the alcohol hit them all at once an hour later. This is incredibly dangerous.
If someone is vomiting while unconscious, cannot be woken up, or has slow, irregular breathing, that’s a medical emergency. The "sleep it off" method is how people die from respiratory failure or aspiration.
Actionable Steps for Responsible Management
If you are going to consume alcohol, do it with a plan.
- Check the label. Know the ABV of what you’re pouring. A "heavy pour" of wine can easily be two standard servings.
- The One-to-One Rule. One glass of water for every alcoholic beverage. It’s the oldest trick in the book because it works. It forces you to slow down and keeps you hydrated.
- Eat before, not during. Once the alcohol is in your small intestine, the pizza you eat at 2 AM isn't doing much for your sobriety; it's just extra calories.
- Set a hard stop. Decide how many drinks you’re having before you have the first one. Your "drunk self" is a terrible decision-maker.
Understanding how to get drunk safely requires acknowledging that alcohol is a toxin that the body is working very hard to remove. Respecting that biological process is the difference between a fun night out and a dangerous medical situation. Stick to the science, watch your pace, and never assume your "feelings" are an accurate measure of your actual blood alcohol level.
