Alcohol and Drug Use Among Teens

What is alcohol and drug use among teens?

Alcohol and drug use means that a teen drinks alcoholic beverages or uses drugs such as marijuana, prescription medications without a doctor’s order, or illegal substances. These substances affect your brain and body, sometimes causing a "high" or altered mood. For example, alcohol can make you feel relaxed or more social, while drugs like marijuana may change how you think or feel. It’s important to know that these effects come with risks. Using alcohol or drugs can interfere with how your brain develops, affect your school performance, and increase the chance of accidents or risky behavior.

Many teens try these substances because of curiosity, peer pressure, or stress, but it’s vital to understand what you’re putting into your body and how it changes you. Alcohol is a drug that slows down your brain’s actions, making it harder to think clearly or react quickly. Other drugs work differently but still affect your brain’s control over judgment and movement.

How does alcohol and drug use work in the body?

When you drink alcohol, it is absorbed into your bloodstream through your stomach and intestines. It travels to your brain, where it slows down communication between nerve cells. This causes you to feel relaxed, less inhibited, or sometimes dizzy. For example, if you drink two beers over an hour, you might feel more confident or talkative, but your reaction time will slow down, and your coordination might suffer. Drinking more can lead to slurred speech, nausea, or even blackouts.

Drugs like marijuana contain chemicals that attach to brain receptors, changing how your brain processes information and controls emotions. Using these drugs can lead to memory problems or difficulty concentrating. Using prescription drugs not meant for you, like stimulants or painkillers, can cause dangerous side effects, including addiction or overdose.

Both alcohol and drugs can impair your ability to make good decisions, increase risky behavior, and affect your mood and health long term. The younger you start using, the higher the chance of addiction or mental health problems later.

Why does alcohol and drug use matter to teens?

Your teenage years are a time when your brain is still growing, especially in areas that control decision-making, self-control, and managing emotions. Using alcohol or drugs during this time can slow down or change brain development, making it harder to learn, remember, or control impulses. This can affect your grades, relationships, and future goals.

Besides health, alcohol and drug use also affects safety. For example, drinking and driving or riding with someone who has been drinking can lead to accidents. Using drugs can also put you in dangerous situations or cause legal trouble. Understanding these risks helps you protect yourself.

Additionally, some teens use substances to cope with stress, anxiety, or peer pressure. Knowing healthy ways to handle these feelings, like exercise, talking to someone you trust, or hobbies, can reduce the desire to use alcohol or drugs.
