Addiction to alcohol, also known as alcoholism or alcohol use disorder (AUD), is one of the most common forms of substance abuse in the Western world. Since alcohol is legal and most of the time can be enjoyed socially with few adverse effects, the signs of addiction can be difficult to identify.
- Over 14.5 million people aged 12 and over struggle with an alcohol use disorder in the United States, of which less than 10% receive treatment
- According to the National Survey on Drug Use and Health (NSDUH), in 2019, over 60% of Americans admitted to having drunk alcohol in the past year, though most would not say they had an alcohol problem
More than 65 million Americans report binge drinking or heavy drinking in a one-month period, which is more than 40% of those who drink alcohol

Understanding alcohol addiction
Alcohol is a legal beverage consumed in many forms, most commonly wine, beer, and spirits. In low doses, alcohol can lower anxiety and inhibitions, promoting a relaxed state. It acts as a depressant in larger quantities and can cause loss of motor function, slurred speech, and short-term memory loss.
According to the National Survey on Drug Use and Health (NSDUH), in 2019, over 60% of Americans admitted to having drunk alcohol in the past year, though most would not say they had an alcohol problem. It is possible to consume alcohol without being an alcoholic; however, if your life is negatively affected by alcohol, you may have an alcohol use disorder (AUD) or addiction.
What is an alcoholic?
There is a high possibility that you have come across the terms alcoholic and alcoholism at some point. These terms are widely used to describe someone who has an alcohol use problem and for most people, it is considered the correct terminology for alcohol addiction. However, medical professionals and addiction specialists have been moving away from this term for years.
The reason for this is that these terms simplify alcohol use into very basic terms. In reality, alcohol use and misuse exist on a broad spectrum and there is a vast difference between someone with no alcohol problems and someone with severe alcohol addiction. the term "alcoholism" could be applied to someone who drinks yet experiences no negative impact on their life as easily as it could to someone who is addicted. This does not help to identify alcohol use disorders (AUD) and can mean people with real problems believe they are fine.
Another reason "alcoholic" is not the preferred terminology is that it carries many societal connotations and baggage. These terms underplay alcohol abuse as being part of a wider mental health condition, one that can be treated and managed. Pejorative terms like alcoholic suggest a moral shortcoming that can lead people to not believe they have a mental illness.
For these reasons, most professionals now prefer the terms "alcohol misuse", "unhealthy alcohol use", or "alcohol use disorder" to describe the varying levels of alcohol abuse.
Alcohol use disorder (AUD) encompasses various harmful drinking behaviors, including alcohol abuse, alcohol dependence, and alcohol addiction (alcoholism). Warning signs of alcohol use disorder are related to patterns of drinking, the continuance of alcohol consumption despite negative consequences, and the presence of withdrawal symptoms.
The consumption of an increasing volume of alcohol, particularly if more alcohol is consumed than was intended, or if the individual finds it difficult or impossible to stop drinking, may indicate a problem. Often those with alcohol use disorder develop a tolerance to alcohol, requiring more and more to have the same effects.
Other symptoms of alcoholism may include:
Saying or doing things that hurt others or yourself
Impaired ability to work
Depression or anxiety
Another indicator is if there is an intense craving for alcohol, and a large proportion of time is spent on obtaining alcohol, drinking it, and recovering from a drinking session.
The presence of withdrawal symptoms, if alcohol is not consumed, is also an indicator of alcohol use disorder.
What causes alcohol addiction?
In most cases, a person's likelihood of developing an alcohol use disorder is directly related to their drinking habits, such as frequency of drinking and volume of alcohol consumed. Research also shows that psychological, biological, and social aspects also play a part in an individual’s predisposition to developing an alcohol use disorder.
Some of the contributing factors to developing an AUD are:
A family history of alcoholism
Parental drinking habits
Exposure to trauma in childhood
Drinking alcohol in adolescence
Mental health issues such as depression and anxiety
Psychiatric disorders such as bipolar disorder and antisocial personality disorder.
The exact relationships between other conditions and the development of a disorder are unclear. It is unknown whether these conditions increase the risk of AUD or if they are more likely to develop due to excessive alcohol consumption.

Immediate effects of alcohol
Alcohol is a depressant that affects the central nervous system, causing mental and physical faculties to slow down and become impaired.
This means that alcohol consumed in small doses (1–2 units) can reduce anxiety and stress and make the consumer feel relaxed. For this reason, alcohol is often consumed in social situations where it may reduce anxiety, negate worries about others’ opinions, and boost confidence.
While the early effects of alcohol use are usually fairly mild for most people, prolonged use can cause more severe symptoms. The culture of alcohol consumption in Western countries has also made it difficult to identify the difference between casual use and abuse. The most common differentiator is that abuse typically in a negative impact on one's life, such as:
Illness or physical harm
Issues with work
Trouble focusing without alcohol

Beer comes in many forms, ranging from lagers to ales, and is usually made from a combination of barley, hops, yeast, and water. Unlike other alcoholic drinks, it tends to have a lower alcohol content by volume (ABV), ranging from 1.8% to 11%. The most common beers on the market fall between 4 and 6 percent, with the average adult being intoxicated (over the legal driving limit) after 3 to 5 beers.
Beer consumption has long been associated with social activities; it’s served widely at sporting events and cinemas and is a “go-to” alcoholic drink for social activities such as happy hours. It is also associated with drinking games on college campuses and amongst teenagers and is often the first type of alcoholic drink a young person will consume.
Beer has become even more mainstream in recent years with the increased popularity of microbreweries and craft beers. Craft beer producers are increasingly introducing new flavors and strengths of beers, and while the innovation has added more options for beer lovers, it does pose some risks. Craft beers have a higher ABV on average and can be as strong as 12%, meaning fans of craft beer can quickly build up a tolerance to alcohol, a characteristic warning sign of alcohol addiction.
Wine is traditionally produced by fermenting grapes but can also be made with other fruits. The most common varieties are red and white, depending on the grape used, and have different flavors depending on the level of fermentation, the region of the world it comes from and the type of grape used.
Wine is often viewed in society as a classy or sophisticated drink, with some varieties being very expensive. It is also a mainstay of fine dining and dinner parties, as well as being a collector’s item for connoisseurs. This can make it difficult to identify when someone has an issue with wine consumption. Wine also has reported health benefits that make it a more defensible drink for people with alcohol use disorders.
As with all types of AUDs, the warning signs with wine are the same, even though the socially acceptable nature of it can make it appear less hazardous. If you or someone you care about shows signs of alcohol addiction with wine, such as excessive drinking or as a means of coping with depressive feelings, then there may be an issue.

Liquor, also known as hard alcohol or spirits, includes vodka, gin, whisky, tequila, rum, and a myriad of other beverages. The ABV of liquor is considerably higher than that of beer or wine, typically ranging from 38–60% and reaching as high as 80 or 90%. Due to its high alcohol content, liquor is often consumed in smaller measures, around 1.5 oz for a single measure (25mL in the UK). Liquor is most commonly consumed in one of two ways; either on its own (“neat”) or mixed with a carbonated beverage (a “mixer”).
Grain liquor, such as Everclear, is sometimes referred to as ETOH. You can find out more about ETOH and what it is here.
Carbonation speeds up the rate of absorption of alcohol into the bloodstream, often causing faster intoxication. When consumed in single measures or shots, liquor is rapid and easy to drink, which can quickly lead to a pattern of alcohol abuse.

The term “binge drinking” refers to the consumption of five or more alcoholic drinks in a short time period (e.g. within 2 hours) on at least one occasion in a week. Binge drinking is most commonly associated with a regular pattern of alcohol use on specific days, such as Friday or Saturday nights.
It may not be considered an issue if the individual does not drink the rest of the week, however even occasional binge drinking can lead to harm, and in many cases, prolonged periods of binge drinking can lead to alcohol dependence.

While the effects of alcohol abuse are prominent for most people, some may not realize they have a problem. So-called “high-functioning” alcoholics are able to consume damaging levels of alcohol without it impeding their personal or professional lives.
As the damaging nature of alcohol misuse does not affect high-functioning alcoholics in the same way, many do not realize they have an issue until it is too late, for example, if they start having withdrawal symptoms after short periods of not drinking. A New York Times article estimated that almost half of alcoholics may be high-functioning and that many high-profile professionals, such as doctors or professors, make up a significant portion of this figure.

Alcohol induced blackouts
Blackouts caused by alcohol are gaps in an individual's memory that occur during intoxication. These blackouts occur when a person has consumed enough alcohol to block the communication between short-term and long-term memory in the hippocampus. This creates a gap in the person's memory of the night before as the short-term information is discarded before it can be stored in long-term memory.
There are two types of blackout caused by alcohol, fragmentary blackout and en bloc blackouts. Fragmentary blackouts are more common, where an individual will experience periods of memory separated by no memory at all. These are the more common form of memory blackout when intoxicated by alcohol.
En bloc blackouts are extended periods of complete amnesia, where the person will have no memory at all for hours at a time. These are the most hazardous forms of blackout and are similar to taking high doses of GHB.
Research suggests that alcohol-related blackouts occur when blood alcohol concentration (BAC) reaches 0.16%, the same point where impulse control, coordination, judgment, and decision-making are also impaired. These blackouts are more likely to occur when alcohol enters the bloodstream quickly and is more likely in those who take anti-anxiety and sleep medication.
Blackouts are different from passing out, where the intoxicated person loses consciousness, but are no less dangerous. Blackouts have been linked to serious violent and sexual assaults (notably against women) and the crimes are rarely solved as there is no recollection of the event.
Mixing alcohol and other drugs
Combining alcohol and other substances is both common and dangerous. Alcohol is a central nervous system (CNS) depressant and combined with other drugs, can have wide-ranging effects. For example, mixing cocaine and alcohol promotes the production of a substance called cocaethylene in the liver, which produces feelings of euphoria.

This toxic combination increases the risk of myocardial infarction, stroke, and liver damage and is thought to be the most commonly fatal two-drug combination. Combining alcohol with opiates such as heroin can boost the depressant qualities of both, which can lead to respiratory depression, hypoxia, coma, and death.
Addiction to one substance increases the risk of becoming addicted to others, especially if taken in conjunction with each other to produce different highs. As alcohol is so widely available, the likelihood of combining it with other substances is high.
