These changes can compromise brain function and drive the transition from controlled, occasional use to chronic misuse, which drug addiction can be difficult to control. The changes can endure long after a person stops consuming alcohol, and can contribute to relapse in drinking. Blood alcohol content (BAC) is the amount of alcohol in the bloodstream.

As the stages of intoxication progress, the physical symptoms can become more pronounced and potentially life-threatening. In severe cases, intoxication can lead to coma or even death, emphasizing the importance of seeking medical attention immediately if symptoms are severe or if an individual is unresponsive. These individual factors, alongside the amount and speed of alcohol intake, dictate a person’s blood alcohol content (BAC) and their progression through the stages of intoxication. Someone who consistently engages in heavy drinking will develop a higher tolerance, requiring more alcohol to reach their desired state and to satisfy the body and brain’s cravings.

Learning about BAC, standard drinks, and the effects of heavy drinking helps you understand the stages of drunkenness and how you can avoid them. Alcohol affects the brain and every part of the body on a cellular level. In addition to being the most commonly abused drug, alcohol is probably the most dangerous drug.

Know the Danger Signs and Act Quickly

An intoxicated person at this stage may show slowed reaction times, reduced memory, blurred vision, and a lack of drug addiction coordination. We all know that the brain is the main source of the body’s functions. Imagine putting your brain in a jar filled with alcohol and shaking it up— it’s not a pretty picture.

This is the very pathway implicated in addiction to all substances. If alcohol is consumed in large enough quantities, or for long periods of time, those initial feel-good responses powerfully trigger feelings of pleasure and reward. This profound activation of the reward system can dramatically increase the desire for alcohol, progressively leading to dependence and, ultimately, addiction.

How Alcohol Affects the Brain and Body

Being drunk represents a critical point in alcohol consumption, where the risk of harm—both to the person and to others—grows significantly if drinking continues. Understanding the five stages of intoxication is crucial for promoting safe drinking practices and recognizing when an individual may be at risk due to alcohol consumption. It’s essential for drinkers to be aware of their limits and for those around them to recognize the signs of intoxication to prevent accidents and ensure safety. Responsible drinking involves not only knowing one’s limits but also planning ahead, such as designating a sober driver or arranging for safe transportation. By educating ourselves and others about the effects of alcohol and the stages of intoxication, we can work towards reducing alcohol-related harm and promoting a culture of safety and responsibility. Alcohol intoxication, also known as drunkenness, is a condition that occurs when an individual consumes alcohol in amounts that exceed their body’s ability to metabolize it efficiently.

Prolonged and heavy alcohol consumption permanently changes brain chemistry. When you drink alcohol, your whole body absorbs and feels the effects of it. Blood alcohol content, or blood alcohol concentration, (BAC) measures the amount of alcohol in your blood. It is calculated in grams per 100 milliliters of blood, so a BAC of 0.08 means your blood is 0.08% alcohol by volume. Alcohol is initially absorbed directly through the walls of the stomach and the small intestine, goes into the bloodstream and travels throughout the body including the brain.

As the stages progress, the impairments in judgment and decision-making can become more severe, leading to significant increases in the risk of accidents, injuries, and other adverse outcomes. Recognizing the effects of intoxication on judgment and decision-making is essential for providing appropriate care and support to individuals who have consumed excessive amounts of alcohol. The first stage of intoxication is often referred to as subclinical because the effects of alcohol are not yet apparent through observable behavior. At this stage, the blood alcohol concentration (BAC) is typically below 0.03%.

Alcoholism is a progressive disorder, evolving through various stages that impact individuals both physically and psychologically. Recognizing these stages is crucial for early intervention and effective treatment, highlighting the need for increased awareness about the progression of alcohol use disorder. The primary symptoms of stage three include high tolerance to alcohol, physical symptoms, and more obvious drinking behaviors. The middle stage of alcoholism is when drinking interferes with everyday life. An individual’s reaction may vary depending on the amount they consume.

At this stage, alcohol has entered the bloodstream and begins to affect the central nervous system, leading to a light buzz and the release of endorphins. This results in a sense of happiness and relaxation, making the person feel more social, talkative, and confident. Mild physical effects, such as a warming sensation or light-headedness, may also occur, though the person may not yet recognize they are becoming intoxicated.

When combined with other evidence-based therapies, such as cognitive-behavioral therapy (CBT), MAT can help prevent relapse and increase your chance of recovery. PHPs accept new patients as well as people who have completed an inpatient program of 1 to 2 weeks but still need focused recovery care. Most programs help set up your aftercare once you complete the inpatient portion of your treatment.
