Understanding Alcohol Addiction

Learn about alcohol addiction

Most people are able to have a drink or two without developing any problems. They’re able to have drinks with friends after a long day at work, and go home without suffering any adverse consequences. Other people, however, have developed a problem with drinking and their alcohol use has led to a number of problems in their lives. While it’s common to hear the terms “alcoholism” and “alcohol abuse” used interchangeably, these two terms have very different meanings. Alcohol abuse is a chronic, debilitating disease in which a person is unable to stop consuming alcohol despite the negative effects on their work, interpersonal life, education, or health. Alcoholism, the more severe of the two disorders, is a highly destructive pattern of alcohol usage that involves a physical tolerance and the presence of withdrawal symptoms if alcohol consumption is cut back or stopped.

Contrary to what some think, those who abuse alcohol or have developed alcoholism are not drinking because they lack self-control or are weak. Alcoholism, alcohol abuse, and addiction are diseases that one cannot simply walk away from, even if they seriously want to stop drinking. However, with proper treatment, detox, medication, and therapies, those who struggle with alcohol abuse or alcoholism are able to successfully overcome their addiction and lead happy, healthy, sober lives.


Alcohol addiction statistics

In the U.S., alcohol abuse and alcoholism affects about 10% of women and 20% of men, most of whom begin using alcohol during their teen years. About 15 million people are affected by alcoholism or alcohol abuse. The mortality associated with alcohol abuse and alcoholism is astounding. Nearly 2,000 teens under the age of 21 will die in any given year as a result of alcohol use. In 2011, the number of alcohol-induced deaths (excluding homicide and accidents) was nearly 26,000 individuals. That very same year, nearly 16,000 people died as a result of alcohol-induced liver disease.

Causes and Risk Factors

Causes and risk factors for alcohol addiction

Researchers tend to agree that addiction to alcohol and drugs is not a disease caused by a single cause or factor, but rather by a number of different factors working together. Some of the most common causes and risk factors related to addiction and alcoholism include:

Genetic: People who have first-degree relatives who struggle with addiction are at a higher risk for developing an addiction themselves. However, not all who end up engaging in problematic drinking have a family history of addiction.

Physical: The process of becoming addicted to – and dependent upon – alcohol occurs slowly. Chronic alcohol consumption can change the normal balance of chemicals and nerve pathways in the brain associated with pleasurable sensations, judgment, and the ability to exert control over behaviors.

Environmental: People raised in an environment in which addiction is the norm or where drugs or alcohol are used to cope with life stressors are more likely to develop a problem with addiction. Additionally, people who begin drinking at an early age are at increased risk of developing addiction later in life.

Risk Factors:

  • Having a partner or close friend who drinks regularly
  • Presence of depression and other mental health disorders
  • Steady drinking over time on a regular basis can produce a physical dependence upon alcohol
