Risks of teenage drinking:

Brain Development and Alcohol Abuse

  • Research indicates that the human brain continues to develop into a person’s early 20’s, and that exposure of the developing brain to alcohol may have long-lasting effects on intellectual capabilities and may increase the likelihood of alcohol addiction.
  • The age when drinking starts affects future drinking problems.
  • For each year that the start of drinking is delayed, the risk of later alcohol dependence is reduced by 14 percent.

 

Drinking and Driving

  • Car crashes are the leading cause of death among people ages 15 to 20.
  • About 1,900 people under 21 die every year from car crashes involving underage drinking.
  • Drinking drivers aged 16 to 20 are twice as likely to be involved in a fatal crash as drinking drivers who are 21 or older.

 

Suicide

  • Alcohol use interacts with conditions like depression and stress, and contributes to an estimated 300 teen suicides a year.
  • High school students who drink are twice as likely to have seriously considered attempting suicide, as compared to nondrinkers.
  • High school students who binge drink are four times as likely to have attempted suicide, as compared to nondrinkers.

 

Sexual Behavior

  • Current teen drinkers are more than twice as likely to have had sexual intercourse within the past three months as teens who don’t drink.
  • Higher drinking levels increase the likelihood of sexual activity.
  • Adolescents who drink are more likely to engage in risky sexual activities, like having sex with someone they don’t know or failing to use birth control.

Other Risks

  • Teens that drink alcohol are more likely than nondrinkers to smoke marijuana, use inhalants, or carry a weapon.
  • Binge drinking substantially increases the likelihood of these activities.

 

Academic Performance
Approximately two-thirds of students with “mostly A’s” are non-drinkers, while nearly half of the students with “mostly D’s and F’s” report binge drinking. It is not clear, however, whether academic failure leads to drinking, or vice versa.
