Drug & Alcohol Use in Adolescents

Nearly 70 percent of high school seniors have tried alcohol, 50 percent have taken an illegal drug, and more than 20 percent have used a prescription drug for a non-medical reason, studies show. Research has found the majority of people are most likely to misuse drugs and alcohol during this transformative time.

Why is this the trend?

  • Underdevelopment of the prefrontal cortex
    • The parts of the brain that process reward and pain first mature during childhood. However, the prefrontal cortex – responsible for controlling impulses, emotions, and decision-making – does not mature until people reach their mid-20s. Therefore, adolescents are motivated by the desire to feel pleasure and avoid pain, both of which are associated with drug and alcohol use.
  • Genetic factors
    • Certain genetic traits, for instance a low harm-avoidance personality trait, make individuals more susceptible to using drugs and alcohol.
    • Mental health concerns such as depression and anxiety also increase the likelihood an adolescent will turn to substances.
  • Social environment
    • Teens are more likely to try drugs and alcohol if their friends are also using.
  • Accessibility of drugs
    • Adolescents are at an increased risk of trying substances if they have easy access to them.
  • Family environment

Compared to adults, adolescents are much more likely to hide their substance use from loved ones. Adolescents are also less likely to show signs of a problem because they have a shorter history of use. However, there are still red flags.

What are the signs?

  • Loss of interest in school and hobbies
  • Sudden need for more money and unwillingness to explain spending habits
  • Withdrawal from family and friends, and an increased desire to be alone
  • Change in friends
  • Change in behavior or personality
  • Unresponsiveness to communication
  • Frequent rule-breaking, especially of curfew

While most adolescents who try drugs and alcohol do not have substance use disorders, the likelihood of developing a substance use disorder is greater for people who begin using in their early teens. According to a study, 15.2 percent of people who start drinking by age 14 develop substance use disorders, compared to 2.1 percent of those who wait until they are 21 or older.

What are the effects?

  • Difficulties with schoolwork
  • Relationship problems
  • Loss of interest in normal healthy activities
  • Impaired memory and thinking ability
  • Increased risk of contracting an infectious disease
  • Mental health problems—including substance use disorders
  • Increased possibility of partaking in unsafe sexual activities
  • Overdose
  • Death

The key in the battle against adolescent addiction is time: We need to involve adolescents in professional treatment programs as soon as possible. Adolescents are less likely to seek out help on their own, so it is crucial loved ones help them into treatment.
