Learn / Why Is Alcohol Considered a Drug?
By definition, alcohol is a drug because it impacts the way your brain works. Not everyone sees it that way, partly because we no longer use alcohol for medical reasons. Today, people drink to celebrate, socialize, and relax. But like any other drug, alcohol can lead to addiction.
Alcohol is a psychotropic central nervous system (CNS) depressant.1 Here’s what that means:
When you drink, alcohol slows down communication between your brain cells.2 This makes you feel more relaxed as early as 15 minutes after you start drinking. Your unique metabolism determines how long alcohol stays in your system.
For most people, the liver can only process about 1 drink an hour.3 If you drink more than that, you may feel more intense side 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 due to binge drinking. If you drink beyond your body’s capacity, you can even get alcohol poisoning.
Alcohol also has long-term effects4 on your brain and body. For example, alcohol is a carcinogen, meaning it causes cancer. Long-term drinking wears down the immune system, which makes you more likely to get sick. According to the CDC, excessive drinking contributes to “high blood pressure, heart disease, stroke, liver disease, and digestive problems.” There’s also a link between alcohol and certain mental health issues, like anxiety and depression.
The term “depressant” refers to slowing neural activity,5 not depression as a mental health issue. Certain prescription depressants can even treat anxiety and insomnia. Not every depressant makes you feel depressed.
However, experts point out a link between alcohol and the feeling of sadness.6 According to one study, 1 out of 3 people with alcohol addiction have “experienced episodes of intense depression and/or severe anxiety.” This data suggests that alcohol addiction might indeed cause depression.
Alcohol is highly addictive.7 However, not everyone with alcohol use disorder develops physical dependence. To find the right type of treatment, you can learn about the difference between physical and psychological addiction.
Drinking releases endorphins8—neurochemicals that make you feel euphoric. The more often and heavily you drink, the more your brain will associate good feelings with drinking. So any time you want to feel good, you’ll start craving alcohol. This cycle can quickly lead to addiction.9
Because alcohol is a depressant, suddenly quitting drinking reactivates your central nervous system.10 This leads to physical withdrawal symptoms which can range from being uncomfortable to life-threatening. For some people, fear of these symptoms becomes a barrier to long-term treatment.
Many people abuse alcohol to self-medicate11 anxiety, trauma, and other mental health conditions. This doesn’t always lead to physical dependence. But if you keep drinking in spite of negative consequences, it can still constitute addiction.
According to the National Institute of Health,12 this strategy doesn’t work in the long term:
“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.”
While alcohol is considered a drug, it still has cultural and economic value in the U.S. In fact, alcohol is a $363.33 billion industry.13 Alcohol was illegal in the U.S. during Prohibition, from 1920-1933.14 But the ban didn’t last long. Illegal alcohol was a public health threat, and creating a black market for drinking didn’t serve the economy. This is similar to the recent change in policy around marijuana legalization. When drugs are legal, the government can regulate them for safety and tax them to boost the economy.
Alcohol addiction doesn’t only affect you. It can also impact your wider community:
If you think you might be addicted to alcohol, it’s important to get a professional diagnosis. As you plan to speak to an expert, take stock of your drinking habits. The Diagnostic and Statistical Manual of Mental Disorders (DSM) defines alcohol addiction17 by a few specific criteria:
It’s never too early to ask for help. If you think you have alcohol use disorder, you very well might. An addiction expert can help you decide which type of treatment will best suit your needs.
Everyone’s experience with alcohol addiction is unique. What works for someone else might not be a good fit for you. However, there are a few common treatments for alcohol abuse:
Alcohol addiction recovery is an ongoing process. With the right type of care you can detox safely, learn to recognize triggers, and start building a meaningful life without alcohol. To find the right program for you, explore rehabs for alcohol addiction.
