Alcohol use disorder (AUD), commonly known as alcoholism, is a prevalent medical condition that can have detrimental effects on individuals and those around them. Alcohol is a psychoactive and toxic substance that can induce dependence, and its excessive consumption can lead to severe health issues, including liver failure and an increased risk of certain cancers. In 2019, approximately 2.6 million deaths worldwide were attributed to alcohol consumption, with men accounting for the majority of these fatalities. The road of alcohol often begins with social drinking, progressing through stages of binge drinking and heavy drinking, eventually leading to addiction and end-stage alcoholism, marked by severe health and mental complications.

What You'll Learn
Alcohol use disorder
The road of alcohol can lead people down a path of destruction, impacting their lives and the lives of those around them. AUD can cause individuals to give up important social activities, work obligations, or recreational pursuits in favour of drinking. It can also lead to hazardous behaviour, such as drinking and driving, which can have deadly consequences. In 2023, there were over 12,000 deaths in the United States due to alcohol-impaired driving crashes. Even a small amount of alcohol can impair one's ability to drive safely, as alcohol reduces brain function, impairing thinking, reasoning, and muscle coordination.
People with AUD may continue drinking despite the negative consequences, and their alcohol consumption may increase over time. They may experience withdrawal symptoms when they try to reduce their drinking, making it difficult to stop without professional help. AUD can range from mild to severe, and the severity is assessed by healthcare professionals using criteria from the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). This assessment considers factors such as the impact of drinking on one's life, the presence of withdrawal symptoms, and the level of tolerance.
Treatment for AUD typically involves a combination of medication and behavioural therapy. Three medications have been approved by the U.S. Food and Drug Administration to help reduce alcohol consumption and prevent relapse: naltrexone, acamprosate, and disulfiram. These medications are non-addictive and can be used alongside behavioural treatments such as counselling, talk therapy, and mutual-support groups. With treatment, most people with AUD are able to reduce their alcohol consumption or achieve and maintain sobriety.
If you or someone you know is struggling with alcohol use, it is important to seek help. SAMHSA's National Helpline offers a free, confidential, 24/7 treatment referral and information service for individuals and families facing substance use disorders.

Health complications
Alcohol consumption, even at low levels, can have detrimental effects on health. The more a person drinks, particularly over a long period, the higher their risk of developing alcohol-associated health issues. Alcohol affects not just the liver, but also the brain, gut, pancreas, lungs, cardiovascular system, immune system, and more.
Cardiovascular Problems
Both acute and chronic alcohol use are associated with arrhythmias, even in people with no clinical history of atrial fibrillation or structural disease. Heavy alcohol intake, even a single binge-drinking episode, can alter the heart's electrophysiology, leading to acute arrhythmia. Chronic heavy drinking raises the risk of ischemic heart disease and myocardial infarction (heart attack). It can also cause high blood pressure and weaken the heart muscle, leading to cardiomyopathy and a progressive reduction in heart muscle contractility.
Cancer
There is a strong consensus that alcohol drinking can cause several types of cancer. The more a person drinks, especially over time, the higher their risk of developing an alcohol-associated cancer. Clear patterns have emerged between alcohol consumption and increased risks of head and neck cancers, including oral cavity, pharynx, and larynx cancers, as well as esophageal cancer.
Diabetes and Endocrine Issues
Alcohol can interfere with diabetes management by affecting blood glucose levels. It can also increase the risk of developing type 2 diabetes due to its impact on body weight, blood triglyceride levels, blood pressure, and insulin sensitivity. Alcohol also contributes to endocrine-related health conditions, including thyroid diseases, abnormal cholesterol levels (dyslipidemia), reproductive dysfunction, stress intolerance, and diabetes.
Digestive Problems
Alcohol can damage the epithelial lining of the GI tract, causing inflammation and GI bleeding. It is also associated with an increased risk of gastroesophageal reflux disease and oral cavity cancer.
Mental Health
Alcohol interferes with the brain's communication pathways and can affect its structure and function. These disruptions can change mood and behavior and impair clear thinking and coordination. Alcohol consumption is associated with an increased risk of mental health conditions, including depression and anxiety. It can also lead to learning and memory problems, including dementia.
Infectious Diseases
There is a causal relationship between alcohol use and the incidence or outcomes of infectious diseases such as tuberculosis and HIV. Alcohol consumption during pregnancy also increases the risk of fetal alcohol spectrum disorders (FASDs) and pre-term birth complications.

Driving under the influence
When an individual chooses to drive under the influence, they not only endanger themselves but also put others at risk. In 2019, 298,000 deaths worldwide were caused by alcohol-related road crashes, with 156,000 of those deaths attributed to someone else's drinking. The impact of drunk driving extends beyond the immediate physical harm, as it can also result in legal consequences and financial burdens. In the United States, a citation for driving under the influence can lead to a significant increase in car insurance premiums, and in some cases, the intoxicated driver's car insurance may be automatically declared invalid, making them fully responsible for any damages.
The legal and social consequences of driving under the influence are severe, and they highlight the importance of responsible drinking and safe driving practices. It is essential for individuals to plan ahead when consuming alcohol, such as by designating a sober driver or utilizing alternative transportation options. Additionally, individuals can play a role in preventing drunk driving by reporting impaired drivers to local law enforcement. By taking responsibility and making informed choices, we can help keep ourselves and others safe on the road.
In conclusion, driving under the influence of alcohol is a dangerous and preventable act that can lead to tragic outcomes. It is crucial to recognize the impact of alcohol on driving abilities and to make informed decisions to protect ourselves and those around us. Through education, responsible drinking, and adherence to the law, we can work towards reducing the number of alcohol-related road crashes and creating a safer environment for everyone on the road.

Alcohol-related injuries
Alcohol consumption is linked to a wide range of injuries, from minor to major, and can even be fatal. Alcohol-related injuries can occur in various settings, but one of the most common and dangerous scenarios is on the road.
Road Traffic Accidents
Alcohol is a significant factor in road crashes and traffic fatalities worldwide. In 2023, there were 12,429 alcohol-impaired driving deaths in the United States alone. Even a small amount of alcohol can impact driving ability, and the more one drinks, the higher the risk of an accident. Alcohol impairs thinking, reasoning, and muscle coordination, all of which are crucial for safe driving. It slows down reaction times and impairs judgment, and increases risk-taking behaviour, making driving under the influence extremely dangerous.
Other Common Alcohol-Related Injuries
In addition to road accidents, alcohol consumption is linked to a range of other injuries, including:
- Falls: Alcohol impairs balance and coordination, increasing the risk of falling.
- Drowning: Alcohol affects judgment and swimming abilities, making water-related activities more dangerous.
- Poisoning: Alcohol consumption can lead to alcohol poisoning, a life-threatening condition.
- Burns: Alcohol can increase the risk of accidents involving fire or hot substances.
- Head injuries, fractures, and facial injuries: These can occur in various alcohol-related accidents.
- Unintentional injuries: Even everyday activities can become dangerous when under the influence, such as running across a busy road or dancing on a table.
Reducing the Risk of Alcohol-Related Injuries
It is important to be aware of the risks associated with alcohol consumption and to take steps to reduce the likelihood of harm. This includes following low-risk drinking guidelines, such as limiting the number of drinks consumed in a single session and avoiding binge drinking. Other harm reduction strategies include drinking slowly, drinking with food, alternating with water, and choosing low or no-alcohol alternatives. Planning ahead is also crucial, such as ensuring safe transportation home and avoiding risky activities while under the influence.

Alcohol dependence
The development of alcohol dependence is a complex process influenced by various factors. These include biological, environmental, and social forces that shape an individual's expectations and decisions regarding alcohol consumption. Neuroadaptive changes resulting from prolonged alcohol use contribute to the transition from controlled drinking to more frequent and excessive alcohol consumption. Additionally, genetics play a role, with individuals having an increased risk of developing alcohol use disorder if they have a family history of the condition.
The signs and symptoms of alcohol use disorder vary but generally include an intense craving for alcohol, giving up important social or recreational activities, drinking in hazardous situations, and experiencing withdrawal symptoms when reducing or stopping alcohol consumption. People with alcohol use disorder may also exhibit increased tolerance to alcohol, which can lead to consuming larger quantities to achieve the desired effect.
The consequences of alcohol dependence can be severe and far-reaching. Alcohol is a psychoactive and toxic substance, and excessive consumption can lead to health risks such as liver cirrhosis and an increased incidence of infectious diseases. It is also a significant contributor to road crashes and fatalities, with approximately 34 people in the United States dying daily in drunk-driving crashes. In 2023, there were 12,429 alcohol-impaired driving deaths in the US alone, and even small amounts of alcohol can impair one's ability to drive safely.
Treatment for alcohol dependence typically involves medication and behavioural therapy, with a focus on reducing alcohol consumption or achieving abstinence. Support groups, 12-step programs, and counselling can also be beneficial in managing alcohol use disorder. It is important for individuals struggling with alcohol dependence to seek help and support, as treatment can effectively reduce alcohol consumption and improve overall well-being.

Frequently asked questions
AUD is a common medical condition where people are unable to stop drinking, even if their alcohol use upends their lives and the lives of those around them. It can be mild, moderate, or severe. People with AUD may develop a tolerance to alcohol and exhibit a variety of behaviours that negatively impact their health and personal and professional lives.
Giving up important social, work, or recreational activities because of alcohol, using alcohol in physically hazardous situations, continuing to drink when one has a medical condition or mental disorder that worsens with alcohol, having a high tolerance for alcohol, and experiencing withdrawal symptoms are some signs that someone may have AUD.
Excessive alcohol use can have immediate and long-term health risks, including liver disease, high blood pressure, heart disease, digestive problems, weaker immune system, mental health conditions, memory problems, and relationship issues. It can also increase the risk of certain cancers, such as breast cancer in women.
Alcohol is a substance that reduces brain function, impairing thinking, reasoning, and muscle coordination, which are essential for operating a vehicle safely. As alcohol levels rise in a person's system, the negative effects on the central nervous system increase, leading to an exponential increase in crash risk. Even small amounts of alcohol can affect one's ability to drive safely.
End-stage alcoholism is the final and most destructive stage of alcoholism, typically reached after years of alcohol abuse. Individuals at this stage may experience major organ damage and failure, as well as interpersonal consequences like isolation and job loss. It can also lead to death.
