Why Is Alcohol Addictive for Some People and Not Others?
Alcohol abuse and alcohol addiction are common in the United States. Nearly 6% of American adults and 2% of American adolescents suffer from an alcohol use disorder. Alcohol abuse claims an estimated 88,000 American lives annually. In 2010, it cost the nation $249 billion dollars. Despite these health and economic consequences, less than 7% of American adults and 6% of American adolescents received treatment for their disease. These facts beg the question: why is alcohol addictive?

Alcohol is addictive because it alters the brain’s reward system. This system is important because it supports naturally rewarding behaviors like eating, sleeping, working, socializing, having sex and parenting. With continuous, heavy use, the brain learns to prioritize alcohol over everything else.
The anticipation of alcohol use is registered in the thalamus, the brain’s relay center. Brain cells, known as neurons, generate an electrical signal that causes nearby neurons to release chemical messengers, known as neurotransmitters. These neurotransmitters bind to the receptors on the next neurons, regenerating the electrical signal. This electrochemical messaging continues until the signal reaches the brainstem.
Anticipated or actual alcohol use signals the midbrain structure of the brainstem to release the pleasure neurotransmitter, dopamine. When our brains release dopamine, the dopamine binds to receptors located throughout the brain to influence our emotions, thoughts, and behaviors. Alcohol, like other drugs, produces much more dopamine than natural rewards do, making it addictive.
Long-term alcohol use repeatedly floods the reward system with dopamine. The brain adapts by reducing its dopamine production in response to natural rewards and alcohol. It also decreases the number of dopamine receptors and increases the number of opioid receptors.
Together, these brain changes result in mental and physical alcohol dependence, and the need for greater alcohol consumption to overcome tolerance and avoid withdrawal symptoms. These changes also explain why drugs that block opioid receptors in the brain, like naltrexone, can be used to treat alcohol cravings.
The 2017 National Survey on Drug Use and Health (NSDUH) reports that 86% of American adults have drunk alcohol at some point in their lives. By the age of 15, up to 30% of American adolescents have already tried alcohol.
Some people may successfully limit their alcohol use to an occasional drink or social drinking. Medical advice and national dietary guidelines encourage adults to drink alcohol in moderation: up to 1 drink a day for women and up to 2 drinks a day for men.
Other people may be unable to drink alcohol without abusing it. These individuals may be referred to as binge drinkers or heavy drinkers. Binge drinking is defined as 4 or more drinks for women and 5 or more drinks for men on any occasion.
Heavy alcohol use, defined as binge drinking 5 or more days a month, puts you at risk of developing alcoholism. More than 33% of American adults and nearly 15% of American adolescents binge drink or drink heavily.
Some people have a higher risk of developing an addiction to alcohol. Some may have a predisposition to alcoholism due to genetic factors. Others may have begun drinking at an early age when the areas of the brain used in decision-making and judgment are still being formed. When these individuals face trauma and adversity, they may turn to alcohol to cope. With continuous, heavy use of alcohol under these circumstances, addiction develops.
If a person is finding it difficult to stop drinking alcohol or is experiencing significant consequences from drinking alcohol, they may have an alcohol use disorder. Specific criteria for alcohol use disorder include:
Alcohol use disorder is clinically diagnosed when at least two of these symptoms occur over at least one year. The addiction may be mild, moderate or severe, depending on the number of symptoms experienced. However, all forms of alcohol addiction are harmful and may be deadly. Alcohol addiction is especially dangerous if other drug addictions are present.
Treatment recommendations for alcohol and drug addiction include:
More than anything, patients need to know that they will receive the best possible care.
