Alcohol intoxication symptoms can range from slurred speech and poor coordination to life-threatening conditions like slow breathing, unconsciousness, and seizures. Recognizing these signs early—and knowing when they cross from typical intoxication into dangerous alcohol poisoning territory—can literally mean the difference between life and death.

Common alcohol intoxication symptoms include:

  • Slurred speech and impaired coordination
  • Lowered inhibitions and impaired judgment
  • Drowsiness, nausea, and vomiting

Critical alcohol poisoning symptoms requiring immediate 911 call:

  • Mental confusion or stupor
  • Unconsciousness or inability to be awakened
  • Slow breathing (fewer than 8 breaths per minute)
  • Irregular breathing (10+ seconds between breaths)
  • Seizures
  • Pale, clammy, or bluish skin
  • Low body temperature (hypothermia)

The stakes are genuinely serious. In the United States, acute alcohol intoxication directly causes an average of 2,221 deaths per year, with indirect alcohol-related fatalities adding more than 30,000 additional deaths annually. What starts as a celebration at a party or gathering can quickly turn deadly when alcohol consumption outpaces the body’s ability to process it.

Why Recognizing These Symptoms Matters in Texas

Whether you are worried about a loved one’s behavior, dealing with the fallout from a night of heavy drinking, or already facing legal trouble in Houston, understanding alcohol intoxication symptoms is essential. In Texas, intoxication is more than a health concern—it can lead to serious criminal charges, including public intoxication and DWI, with harsh consequences like fines, possible jail time, and suspension of your driver’s license.

I’m Herman Martinez, founder of The Martinez Law Firm in Houston, and after 25+ years prosecuting and defending criminal cases—including serving as a Chief Prosecutor and City of Houston Judge—I’ve seen how quickly alcohol intoxication symptoms can escalate into both medical emergencies and legal crises. My experience on both sides of the courtroom gives me unique insight into how these situations unfold and how to protect your rights when alcohol-related charges arise in Houston and Harris County.

Recognizing the Danger Zone: Intoxication vs. Alcohol Poisoning

When we talk about drinking, the terms “intoxication” and “alcohol poisoning” often get used interchangeably, but there’s a crucial difference. Understanding this distinction is the first step in recognizing when to act.

Alcohol intoxication occurs when the amount of alcohol we consume leads to behavioral or physical changes, causing our mental and physical abilities to become impaired. It’s the state we enter after having a few drinks, leading to the familiar “buzzed” feeling or even stumbling and slurring words. Think of it as the body’s initial reaction to alcohol, where our judgment and coordination start to go a bit wonky.

Alcohol poisoning, on the other hand, is a much more severe condition. It’s an overdose, a truly serious—and potentially deadly—result of drinking far too much alcohol in a short period. This happens when there’s so much alcohol in our bloodstream that it begins to shut down the brain functions essential for basic life support, like breathing, heart rate, and temperature control. It can affect our gag reflex, potentially leading to coma and even death. It’s a medical emergency that demands immediate attention.

When to Call 911

If you suspect someone in Houston or Harris County has alcohol poisoning, don’t hesitate. Call 911 immediately. Every second counts. Don’t wait for all the critical symptoms to appear; if even one is present, it’s time to get professional medical help.

Here’s a quick comparison to help us distinguish between common intoxication and the critical signs of alcohol poisoning:

Symptom CategoryMild/Moderate Alcohol IntoxicationCritical Alcohol Poisoning – Call 911 Immediately
Mental stateRelaxed, lowered inhibitions, impaired judgment, mood swings, trouble focusing.Mental confusion, stupor, inability to respond normally, or seeming “out of it.”
CoordinationClumsiness, poor balance, stumbling or staggering, slowed reactions.Unconsciousness or cannot be awakened, even with shaking, shouting, or painful stimulation.
SpeechSlurred or slowed speech, difficulty finding words.May be completely unresponsive or only make groaning sounds; cannot hold a coherent conversation.
BreathingTypically normal breathing, though slightly slower than usual.Slow breathing (fewer than 8 breaths per minute) or irregular breathing (10 seconds or more between breaths).
Skin & temperatureWarm or flushed skin, sweating is possible.Pale, cold, clammy, or bluish skin, especially lips or fingernails; low body temperature (hypothermia).
Other symptomsDrowsiness, nausea, vomiting, headache, temporary memory gaps (blackouts possible at higher BAC).Repeated vomiting, seizures, choking risk, or no response after vomiting; signs of shock or very weak pulse.

For a comprehensive list of symptoms and causes, you can refer to the Mayo Clinic’s guide on alcohol poisoning.

When alcohol consumption leads to medical emergencies, the short-term consequences can be severe and life-threatening. These include:

  • Choking: A depressed gag reflex due to alcohol poisoning significantly increases the risk of choking on vomit.
  • Severe Dehydration: Intense vomiting can lead to dangerous fluid loss, causing extremely low blood pressure and a fast heart rate.
  • Seizures: Alcohol poisoning can trigger seizures, especially as the body tries to process the excessive alcohol.
  • Hypothermia: Alcohol can lower body temperature to dangerously cold levels, leading to hypothermia.
  • Brain Damage or Death: In its most severe forms, alcohol poisoning can lead to permanent brain damage or even death due to respiratory arrest or cardiac arrest. The brain’s vital life-support functions can simply shut down.

Beyond the immediate crisis, repeated incidents of alcohol intoxication symptoms and poisoning can contribute to serious long-term health problems. Chronic alcohol use can lead to liver diseases like alcoholic hepatitis and cirrhosis, as well as heart problems, including an increased risk of heart failure and arrhythmias like “holiday heart syndrome.” Neurological issues such as dementia, cerebellar degeneration, and peripheral neuropathy are also potential long-term complications.

If someone experiences alcohol poisoning, medical treatment in a hospital setting is crucial. This typically involves:

  • Continuous Monitoring: Medical staff will closely watch vital signs like breathing, heart rate, and body temperature.
  • Intravenous (IV) Fluids: These help combat dehydration and stabilize blood sugar levels. Often, B vitamins are administered to prevent serious neurological complications like Wernicke encephalopathy.
  • Breathing Support: In severe cases, a person may need intubation to protect their airway and ensure adequate breathing until the alcohol’s effects subside.

Here in Houston and Harris County, we understand that alcohol intoxication symptoms don’t just lead to medical concerns; they can also lead to significant legal consequences. What might start as a fun night out can quickly turn into a legal mess if you or a loved one are deemed “intoxicated” under Texas law.

One common charge we see is Public Intoxication (PI). Under Texas Penal Code § 49.02, it is against the law for any person to be in public under the influence of alcohol and/or drugs to the extent that they may endanger themselves or others. This means that if you’re out in a public place in Houston and your alcohol intoxication symptoms are severe enough that you can’t care for your own safety, or you pose a risk to others, you could face a PI charge. This can happen regardless of your specific Blood Alcohol Concentration (BAC) level.

Even more serious are Texas DWI laws. DWI stands for Driving While Intoxicated, and it’s a charge we take very seriously at The Martinez Law Firm. In Texas, you are legally “intoxicated” if you have an alcohol concentration of 0.08 percent or more in your blood, or if you don’t have the normal use of your mental or physical faculties because of alcohol or other substances. It’s important to know that for commercial drivers in Texas, the BAC limit is even lower at 0.04%, and for drivers under 21, it’s a strict 0.01% with a “zero tolerance” policy.

Legal Penalties in Texas

The potential legal penalties for DWI in Houston and Harris County can be severe:

  • First DWI Offense: Typically a Class B misdemeanor, carrying penalties such as up to 180 days in jail, fines up to $2,000, and a driver’s license suspension for 90 days to one year. You may also face annual fees to retain your license.
  • Second DWI Offense: Usually a Class A misdemeanor, with penalties that can include 30 days to one year in jail, fines up to $4,000, and a driver’s license suspension for up to two years.
  • Third or Subsequent DWI Offenses: These are often charged as felonies, with penalties escalating to 2 to 10 years in prison and fines up to $10,000, along with lengthy license suspensions.

Additionally, aggravating factors, such as having a child passenger under 15, or a BAC of 0.15% or higher, can lift a DWI charge and its associated penalties.

Given these serious consequences, the critical role of experienced legal counsel cannot be overstated. If you’re facing a public intoxication charge or a DWI in Houston or Harris County, having a knowledgeable attorney by your side is essential. We can help you understand your rights, steer the complexities of the legal system, and fight for the best possible outcome.

Frequently Asked Questions about Alcohol Intoxication Symptoms

We hear a lot of questions about alcohol and its effects, especially when people are trying to understand the line between having a good time and facing a serious health or legal crisis. Here are some common questions we encounter:

How long do alcohol intoxication symptoms last?

The duration of alcohol intoxication symptoms depends largely on how quickly our body can metabolize, or process, the alcohol. On average, our body breaks down alcohol at a rate of roughly 0.015% BAC per hour. This means it takes time for alcohol to leave our system, and there’s no quick fix to speed up the process.

Factors affecting how long symptoms last include:

  • Amount and Type of Alcohol Consumed: More drinks, especially higher proof alcohol, mean a longer duration.
  • Body Weight and Sex: Generally, people with less body weight and women tend to reach higher BACs and experience symptoms for longer, even after consuming the same amount of alcohol as a heavier person or a man. This is due to differences in body water content and metabolism.
  • Food Intake: Drinking on an empty stomach allows alcohol to be absorbed much faster, leading to quicker onset and potentially longer-lasting symptoms. Eating before or while drinking slows absorption.
  • Liver Function: Our liver does most of the heavy lifting when it comes to processing alcohol. Liver health can impact how efficiently alcohol is cleared.
  • Age, Medications, and Health Conditions: Older individuals, those on certain medications, or people with pre-existing health issues may metabolize alcohol more slowly.

Even after the acute alcohol intoxication symptoms subside, lingering effects like a headache, nausea, and fatigue (the classic “hangover”) can persist for up to 24 hours or more.

Can you have alcohol poisoning without being unconscious?

Yes, absolutely. While unconsciousness is one of the most alarming and critical signs of alcohol poisoning, it is not the only one. A person can be experiencing severe alcohol intoxication symptoms that qualify as alcohol poisoning even if they are still conscious.

For example, someone might be conscious but severely confused, unable to communicate coherently, vomiting uncontrollably, or exhibiting extremely slow and irregular breathing. These are all critical signs that demand immediate medical attention, even if the person can still be roused or is technically awake. Unconsciousness is often a late-stage indicator, meaning the body’s vital functions are already severely compromised.

What is the difference between a hangover and alcohol poisoning?

This is a really important distinction, and one that often gets confused.

A hangover is the unpleasant collection of alcohol intoxication symptoms that typically occurs hours after drinking, once the BAC has dropped significantly, often to zero. These symptoms include headache, nausea, fatigue, sensitivity to light and sound, and general malaise. While uncomfortable, hangovers are generally not life-threatening. They’re a sign your body is recovering from excessive alcohol consumption.

Alcohol poisoning, as we’ve discussed, is a life-threatening medical emergency. It occurs when a person’s BAC is dangerously high, actively shutting down vital bodily functions. The key differentiators are the severity of the symptoms and the active danger to life:

  • Breathing: With alcohol poisoning, breathing can become dangerously slow (fewer than 8 breaths per minute) or irregular (10 seconds or more between breaths). A hangover doesn’t typically affect breathing this way.
  • Consciousness: While you might feel drowsy with a hangover, alcohol poisoning can lead to stupor, inability to be awakened, or complete unconsciousness.
  • Body Temperature: Alcohol poisoning can cause a dangerous drop in body temperature (hypothermia), leading to pale, clammy, or bluish skin. Hangovers don’t typically cause these severe physiological changes.
  • Gag Reflex: Alcohol poisoning can suppress the gag reflex, increasing the risk of choking on vomit, a risk not present with a typical hangover.

If you’re ever in doubt, always err on the side of caution and seek medical help. A hangover will eventually pass, but alcohol poisoning requires immediate intervention.

Prevention and Getting Help

Preventing alcohol intoxication symptoms from escalating into a dangerous situation starts with responsible choices. We encourage everyone to:

  • Pace Yourself: Drink slowly. Your body can only process about one standard drink per hour. Don’t try to outpace your liver!
  • Eat Food: Never drink on an empty stomach. Food slows down alcohol absorption, giving your body more time to process it.
  • Stay Hydrated: Alternate alcoholic beverages with water or non-alcoholic drinks. This helps prevent dehydration, which can worsen alcohol intoxication symptoms.
  • Know Your Limits: Understand how much alcohol your body can handle. A “standard drink” is 12 fluid ounces of regular beer (5% alcohol), 5 fluid ounces of wine (12% alcohol), or 1.5 fluid ounces of 80-proof distilled spirits (40% alcohol). These amounts can vary, so always check labels!
  • Talk to Teens: Open communication with teenagers about the dangers of binge drinking and alcohol intoxication symptoms is crucial. Educate them about the risks and how to get help. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) provides valuable resources on this topic.
  • Avoid Mixing: Never combine alcohol with other drugs, especially those that depress the central nervous system, like opioids, sedatives, or even some antihistamines. This combination can be deadly.
  • Safe Storage: Keep all alcohol-containing products, including non-beverage items like rubbing alcohol or mouthwash, safely stored and out of reach of children or vulnerable individuals.
