Why Is Alcohol Considered a Drug?

By definition, alcohol is a drug because it impacts the way your brain works.¹ Not everyone sees it that way, partly because alcohol isn’t often used for medical reasons.

Many people drink to celebrate, socialize, and relax. But like other drugs, alcohol can lead to addiction.

Alcohol: What Makes It a Drug?

Alcohol is a psychotropic central nervous system (CNS) depressant.¹ Here's what that means:

• Psychotropic drugs affect the way you think and feel. In other words, alcohol can change your mood, thoughts, and behavior.¹ Other psychotropic drugs include cocaine, marijuana, and nicotine.
• Central nervous system depressants slow down your brain activity.² This relaxes your muscles and can make you feel at ease. Other depressants include prescription drugs like Xanax, Valium, and Klonopin.

How Alcohol Affects Your Brain and Body

When you drink, alcohol slows down communication between your brain cells.³ This can make you feel more relaxed as early as 15 minutes after you start drinking.³ Your metabolism can affect how long alcohol stays in your system.

For many people, the liver can only process about one drink an hour.⁴ If you drink more than that, you may feel more intense effects. These can include lower inhibitions, intense emotions, and a loss of muscle coordination.

You might even black out, which is when your brain stops recording memories during heavy drinking. If you drink beyond your body’s capacity, you can get alcohol poisoning.

Alcohol also has long-term effects on your brain and body.⁵ For example, alcohol is a carcinogen, meaning it causes cancer.⁶

Long-term drinking can weaken your immune system, which can make it easier to get sick. According to the Centers for Disease Control (CDC), excessive drinking contributes to "high blood pressure, heart disease, stroke, liver disease, and digestive problems."⁵ There’s also a link between alcohol use and some mental health concerns, like anxiety and depression.⁷

Alcohol Is Classified as a Depressant

The term "depressant" refers to slowing neural activity, not depression as a mental health concern.² Certain prescription depressants can treat anxiety and insomnia. Not every depressant makes you feel depressed.

Experts also describe a link between alcohol use, anxiety, and depressive conditions.⁷ For example, some research has found that many people with alcohol dependence also report significant symptoms of depression or anxiety.⁹ This overlap can make it helpful to treat alcohol use and mental health together.

Is Alcohol Addictive?

Alcohol use disorder (AUD) is a common and treatable medical diagnosis. According to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), an estimated 27.9 million people in the U.S. had AUD in the past year, though not everyone with AUD develops physical dependence on alcohol.⁸

To find the right type of treatment, you can learn about the difference between physical and psychological addiction.

Physical Addiction

Drinking can release endorphins, which are neurochemicals that affect pleasure and reward in your brain.⁹ Over time, your brain may connect drinking with feeling better, which can increase cravings.¹⁰ This cycle can contribute to addiction.¹⁰

Because alcohol is a depressant, quitting suddenly can reactivate your central nervous system.¹¹ This can lead to withdrawal symptoms that range from uncomfortable to life-threatening.¹¹ In some cases, worry about withdrawal becomes a barrier to getting help.

Psychological Addiction

Some people use alcohol to cope with anxiety, trauma, and other mental health conditions.¹² This doesn’t always lead to physical dependence. But if you keep drinking despite negative consequences, that can still be a sign of addiction.

According to the National Institutes of Health, drinking to cope can feel helpful in the moment, but it may make negative emotions worse over time.¹³

“Drinking to cope with stress—while it may provide temporary relief from emotional discomfort—tends to enhance negative emotional states between bouts of alcohol consumption. These changes can motivate further drinking and cause an individual to become stuck in an unhealthy cycle of alcohol consumption.”

Why Is Alcohol Legal in the U.S.?

While alcohol is considered a drug, it has cultural and economic value in the U.S. For example, alcohol retail supports millions of jobs and contributes billions of dollars in economic impact.¹⁴

Alcohol was illegal in the U.S. during Prohibition, from 1920 to 1933.¹⁵ But the ban didn’t last. Unregulated alcohol created health risks, and the illegal market created other harms. When alcohol is legal, the government can regulate it for safety and tax it.

How Alcohol Misuse Affects Your Loved Ones

Alcohol addiction doesn’t only affect you. It can also affect your wider community:

• Drinking takes up time. You might spend long nights away from home or feel too hungover to enjoy other activities with family.
• Alcohol can lead to conflict. Alcohol can impair judgment, and you might act differently when you’re drinking. Some research also links alcohol use with increased aggression in some situations.¹⁶
• Drinking can damage trust. Many people try to hide alcohol misuse.¹⁷ You might want to avoid consequences at work or protect your loved ones from the truth. If you have high-functioning alcohol addiction, this could go on for some time. But over time, your loved ones might notice changes and feel hurt.
• Alcohol addiction is expensive. Drinking can drain your finances, which may add stress to partnerships and families.
• Alcohol can affect your work. Alcohol can make it harder to focus.³ Being intoxicated, hungover, or sleep deprived at work might damage your professional relationships. You might also risk losing your job, which could affect your family.
• Drinking can cause legal problems. Alcohol misuse can impair your judgment. If you drive after drinking, you could get in an accident or get arrested. Even if no one gets hurt, it can damage your reputation and your closest relationships.

Signs and Symptoms of Alcohol Misuse

If you think you might be addicted to alcohol, getting a professional assessment can help. As you plan to speak with a professional, it may help to take stock of your drinking patterns. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR) defines alcohol use disorder using specific criteria.¹⁸

• Drinking more alcohol, or for longer, than you originally planned.
• Wanting to cut down or stop drinking but not being able to.
• Spending a lot of time getting alcohol, drinking, or recovering from drinking.
• Having strong cravings or urges to drink.
• Drinking causing problems at work, school, or home responsibilities.
• Continuing to drink even though it’s hurting relationships or causing social problems.
• Giving up or reducing important activities because of drinking.
• Drinking in situations where it’s unsafe (like driving or operating machinery).
• Continuing to drink even though you know it’s causing physical or mental health problems.
• Needing more alcohol to feel the same effect (tolerance).
• Having withdrawal symptoms when alcohol wears off, or drinking to avoid withdrawal symptoms.

When to Seek Professional Help for Alcohol Use

Getting help early can make treatment feel more manageable. If you think you may have alcohol use disorder, an addiction specialist can help you explore treatment options that fit your needs.

Treatment Options

Everyone’s experience with alcohol addiction is unique. What works for someone else might not be a good fit for you. Here are some common treatment options for alcohol use disorder:

• Alcohol detox: Quitting alcohol suddenly can cause dangerous withdrawal symptoms.¹⁹ In a medical detox program, your care team can monitor symptoms and support your safety. Some rehab programs ask you to complete detox before you start longer-term treatment.
• Residential rehab for alcohol addiction: In these programs, you’ll live on-site at a treatment center. Your length of stay in rehab can range from a few days to several weeks or longer. Many programs offer a mix of services, such as 1:1 therapy, support groups, and medical care.
• Partial hospitalization program (PHP): Also known as day treatment, in a PHP, you’ll live at home but follow an intensive treatment schedule. Some programs require about 40 hours per week on-site.
• Intensive outpatient program (IOP): An IOP provides structured therapy and support for people who don’t require all-day treatment. Outpatient care is often used as step-down care after residential treatment. It can also be an option if you want to keep working or going to school while attending treatment.
• Sober living: Sober living environments can help you transition out of residential treatment. You’ll live with other people in recovery while keeping access to work, school, and your community.

Recovery from alcohol use disorder is an ongoing process, and many people do recover. According to SAMHSA data, 23.5 million (74.3%) U.S. adults who once felt they had a problem with alcohol or drugs now consider themselves to be in recovery or recovered.²⁰

With the right support and treatment, you can work toward safer withdrawal management, learn your triggers, and build a healthier life beyond alcohol use. To find the right program for you, explore rehabs for alcohol addiction.
