    Underage Drinking

    Underage drinking is a serious public health problem in the United States. Alcohol is the most widely used substance of abuse among America’s youth, and drinking by young people poses enormous health and safety risks.

    The consequences of underage drinking can affect everyone—regardless of age or drinking status. We all feel the effects of the aggressive behavior, property damage, injuries, violence, and deaths that can result from underage drinking. This is not simply a problem for some families—it is a nationwide concern.

    Underage Drinking Statistics

    Many young people drink alcohol

    • By age 15, about 33 percent of teens have had at least 1 drink.1
    • By age 18, about 60 percent of teens have had at least 1 drink.1
    • In 2015, 7.7 million young people ages 12–20 reported that they drank alcohol beyond “just a few sips” in the past month.2

    Youth ages 12 to 20 often binge drink

    People ages 12 through 20 drink 11 percent of all alcohol consumed in the United States.3 Although youth drink less often than adults do, when they do drink, they drink more. That is because young people consume more than 90 percent of their alcohol by binge drinking. Binge drinking is consuming many drinks on an occasion (see box). Drinking alcohol and binge drinking become more prevalent as young people get older.

    • 5.1 million young people reported binge drinking (for males 5 or more drinks and for females 4 or more drinks on the same occasion within a few hours) at least once in the past month.2
    • 1.3 million young people reported binge drinking on 5 or more days over the past month.2

    More adolescents use alcohol than cigarettes or marijuana

    Drinking patterns vary by age and gender

    As adolescents get older, they tend to drink more. Prevalence of drinking by boys and girls is similar, although among older adolescents, boys binge more than girls.

    NOTE. Binge Alcohol Use is defined as drinking 5 or more drinks on the same occasion for boys or 4 or more drinks on the same occasion for girls on at least one day in the past 30 days.

    Underage Drinking Is Dangerous

    Underage drinking poses a range of risks and negative consequences. It is dangerous because it:

    Causes many deaths

    Based on data from 2006–2010, the Centers for Disease Control and Prevention (CDC) estimates that, on average, alcohol is a factor in the deaths of 4,358 young people under age 21 each year.4 This includes:

    • 1,580 deaths from motor vehicle crashes
    • 1,269 from homicides
    • 245 from alcohol poisoning, falls, burns, and drowning
    • 492 from suicides

    Causes many injuries

    Drinking alcohol can cause kids to have accidents and get hurt. In 2011 alone, about 188,000 people under age 21 visited an emergency room for alcohol-related injuries.5

    Impairs judgment

    Drinking can lead to poor decisions about engaging in risky behavior, including drinking and driving, sexual activity (such as unprotected sex), and aggressive or violent behavior.

    Increases the risk of physical and sexual assault

    Underage youth who drink are more likely to carry out or be the victim of a physical or sexual assault after drinking than others their age who do not drink.

    Can lead to other problems

    Drinking may cause youth to have trouble in school or with the law. Drinking alcohol also is associated with the use of other drugs.

    Increases the risk of alcohol problems later in life

    Research shows that people who start drinking before the age of 15 are 4 times more likely to meet the criteria for alcohol dependence at some point in their lives.

    Interferes with brain development

    Research shows that young people’s brains keep developing well into their 20s. Alcohol can alter this development, potentially affecting both brain structure and function. This may cause cognitive or learning problems and/or make the brain more prone to alcohol dependence. This is especially a risk when people start drinking young and drink heavily.

    Preventing Underage Drinking

    Preventing underage drinking is a complex challenge. Any successful approach must consider many factors, including:

    • Genetics
    • Personality
    • Rate of maturation and development
    • Level of risk
    • Social factors
    • Environmental factors

    Several key approaches have been found to be successful. They are:7

    Environmental interventions

    This approach makes alcohol harder to get—for example, by raising the price of alcohol and keeping the minimum drinking age at 21. Enacting zero-tolerance laws that outlaw driving after any amount of drinking for people under 21 also can help prevent problems.

    Individual-level interventions

    This approach seeks to change the way young people think about alcohol, so they are better able to resist pressures to drink.

    School-based interventions

    These are programs that provide students with the knowledge, skills, motivation, and opportunities they need to remain alcohol free.

    Family-based interventions

    These are efforts to empower parents to set and enforce clear rules against drinking, as well as improve communication between children and parents about alcohol.

    The Role Parents Play

    Parents and teachers can play a big role in shaping young people’s attitudes toward drinking. Parents in particular can have either a positive or negative influence.

    Parents can help their children avoid alcohol problems by:

    • Talking about the dangers of drinking
    • Drinking responsibly, if they choose to drink
    • Serving as positive role models in general
    • Not making alcohol available
    • Getting to know their children’s friends
    • Having regular conversations about life in general
    • Connecting with other parents about sending clear messages about the importance of not drinking alcohol
    • Supervising all parties to make sure there is no alcohol
    • Encouraging kids to participate in healthy and fun activities that do not involve alcohol

    Research shows that children whose parents are actively involved in their lives are less likely to drink alcohol.

    On the other hand, research shows that a child with a parent who binge drinks is much more likely to binge drink than a child whose parents do not binge drink.

    Warning Signs of Underage Drinking

    Adolescence is a time of change and growth, including behavior changes. These changes usually are a normal part of growing up but sometimes can point to an alcohol problem. Parents and teachers should pay close attention to the following warning signs that may indicate underage drinking:

    • Changes in mood, including anger and irritability
    • Academic and/or behavioral problems in school
    • Rebelliousness
    • Changing groups of friends
    • Low energy level
    • Less interest in activities and/or care in appearance
    • Finding alcohol among a young person’s things
    • Smelling alcohol on a young person’s breath
    • Problems concentrating and/or remembering
    • Slurred speech
    • Coordination problems

    Treating Underage Drinking Problems

    Screening young people for alcohol use and alcohol use disorder is very important and may avoid problems down the road. Screening by a health practitioner (e.g., pediatrician) provides an opportunity to identify problems early and address them before they escalate. It also allows young people to ask questions of a knowledgeable adult. NIAAA and the American Academy of Pediatrics both recommend that all youth be regularly screened for alcohol use.

    Some young people can experience serious problems as a result of drinking, including alcohol use disorder, which require intervention by trained professionals. Professional treatment options include:

    • Seeing a counselor, psychologist, psychiatrist, or other trained professional
    • Participating in outpatient or inpatient treatment at a substance abuse treatment facility or other licensed program
