What This Article is About

It’s Friday night, and teens are hanging out. Maybe they’re in a basement, at a friend’s house while the parents are out, or at a party after a big game.

Someone came to the event with a bottle of alcohol. “Come on, everyone does this,” a friend says. “It’s just a few drinks.” By the end of the night, those “few drinks” have turned into six or seven, and the teens involved are facing a potentially dangerous situation. This scene plays out among teens and young adults everywhere—in high school, in college, and in the years right after.

Binge drinking is one of the biggest health risks facing young people today. Here’s what it is, why it happens, and what parents can actually do about it.

What Is Binge Drinking?

Someone binge drinks when they consume a lot of alcohol in a short amount of time, making their blood alcohol level dangerously high.

The amount of alcohol that counts as binge drinking depends on a person’s body:

For cisgender girls and women: 4 or more drinks within a few hours.

For cisgender boys and men: 5 or more drinks within a few hours.

One drink equals:

• 5 ounces of wine, OR
• 12 ounces of beer, OR
• 1.5 ounces of hard liquor.

How Common Is It?

According to the 2024 National Survey on Drug Use and Health (NSDUH) about 1 in 29 adolescents (ages 12–17 and more than 1 in 4 young adults (ages 18–25) reported binge drinking in the past month.¹

For college students and other young adults (and even high schoolers), binge drinking often happens during:

• College parties
• Sporting events
• Spring break
• Holidays
• Graduation
• Celebrations like birthdays and 21st birthdays

Why Do Teens and Young Adults Binge Drink?

There’s no single answer. However, there are usually a few things in particular that are going on:

1. Young brains chase excitement. Teen and young adult brains are wired to seek out new, thrilling experiences without always thinking through the consequences.
2. They think everyone’s doing it — except they’re not. Many young people think binge drinking is way more common than it is. In reality, most don’t drink this heavily.
3. Personality and habits play a role. Teens who are impulsive or like breaking rules are more likely to binge drink.²
4. Easy access makes it worse. When alcohol is cheap and easy to get, whether at home, through older friends, or at parties with little supervision, more young people overdo it—sometimes, simply because it’s there.

What Are the Risks?

Binge drinking isn’t just a “bad night”: it’s linked to serious and even fatal health and safety issues, including:

• Higher risk of injury, car crashes and falls
• Alcohol poisoning
• Increased violence
• Blackouts
• Unsafe or unwanted sex
• Weakened immune system
• Alcohol use disorder (including addiction)
• Heart disease, high blood pressure, and liver damage
• Increased risk of certain cancers, including mouth, throat, liver, and breast cancer

Even for those old enough to drink legally, health guidelines suggest sticking to no more than 1 drink a day for women and 2 for men on days they choose to drink.³

What Can Parents Do?

You actually have much more of an influence over your child’s decision to drink, and that starts much earlier than most people think.

• Speak up early and often. Research shows that teens whose parents clearly disapprove of underage drinking throughout their adolescence are less likely to binge drink later on. Letting a teen drink at home to “practice” doesn’t lower their risk. In fact, studies suggest that children who are allowed to drink at home are more likely to develop issues with alcohol.
• Stay connected as they get older and more independent. A regular check-in like a weekly call or a standing dinner keeps communication open. You don’t need to talk about alcohol every time, but staying up to date on their day-to-day life can help you notice if something is off.
• Watch for warning signs. Skipping responsibilities, disrupted sleep, or trouble concentrating can all be signs of a drinking problem.
• Get help if you’re worried. If you suspect a problem, try to talk in person and keep a calm, supportive tone. A doctor, a therapist, a treatment center, or another substance use disorder professional can help you figure out the next right step. Schools, colleges, and community health centers often have counselors who can assess for alcohol problems and connect young people to treatment.

Frequently Asked Questions

What counts as binge drinking?

4 or more drinks in a few hours for women, or 5 or more for men.

Is binge drinking getting better or worse among teens and young adults?

Better, overall—it’s dropped from about 40% to 32% over the past decade. But high-intensity drinking (double the amount that counts as binge drinking) is still common, especially among young men.⁴

Why do teens and young adults binge drink even when they know it’s risky?

A mix of reasons: young brains are drawn to risk-taking (especially those who are characteristically impulsive), many teens overestimate how common heavy drinking really is, binge drinking can temporarily make them feel better (due to stress, untreated mental health conditions, etc.), and easy access to alcohol makes it more likely.

Does letting my teen drink at home make them safer later on?

No. Research shows the opposite—teens whose parents clearly discourage alcohol use are less likely to binge drink as they get older.

What’s the most useful thing I can do as my child gets older and more independent?

Stay in regular contact. Even everyday check-ins about friends, school, or work help you catch warning signs early and keep the door open for honest conversations.
