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. 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.
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.
