Teen Alcohol and Drug Use

Condition Basics

What is teen substance use?

Many teens try substances like alcohol or drugs. Some try them only a few times and stop. Others may continue to use them on a more regular basis. Substances teens may try include tobacco and other nicotine products, alcohol, cannabis or other drugs, household products (inhalants), and prescription or over-the-counter medicines.

Why do teens use alcohol or drugs?

Teens may use alcohol or drugs for many reasons. They may do it because they:

  • Want to fit in with (or may be pressured by) certain friends or groups.
  • Like the way it makes them feel.
  • Believe it makes them more grown up.
  • Want to escape from their problems. For example, some teens may use drugs to try to:
    • Avoid the symptoms of mental health conditions, such as attention deficit hyperactivity disorder (ADHD) or depression.
    • Ease feelings of insecurity.
    • Forget about past trauma or abuse.

What problems can teen substance use cause?

Substance use can become a serious issue and lead to long-term problems, injury, and even death. For example:

  • Teens who keep using substances may form a strong need for them. This can lead to substance use disorder.
  • Substance use can affect growth and development. Teens who use alcohol and drugs may have trouble finding their identity, building relationships, and preparing for their future.
  • Substance use can affect memory and learning.
  • Substance use can lead to unprotected sex. This increases the risk of unwanted pregnancy and sexually transmitted infections (STIs).
  • Tobacco use can cause cancer and heart and lung problems.
  • Even casual use of certain drugs can cause severe health problems, such as an overdose or brain damage. Many illegal drugs are made in home labs, so they may contain unsafe substances.
  • Alcohol and drug use is a leading cause of teen death or injury related to car crashes, suicides, violence, and drowning.

How do you know if your teen is using drugs or alcohol?

You may worry that your teen is using drugs or alcohol if they become withdrawn or negative. But these behaviours are common for teens. They may also be signs of a mental health condition, such as depression.

It's important not to accuse your teen unfairly. Tell your teen that you are concerned. Try to find out why their behaviour has changed.

Experts recommend that parents look for a pattern or a number of changes, not just one or two. Signs that a teen may be using drugs or alcohol include:

  • Having red and glassy eyes and often using eyedrops and breath mints.
  • Paying less attention to dressing and grooming.
  • Loss of appetite or unexplained weight loss.
  • Doing worse in school or skipping school.
  • Acting secretive or sneaky.
  • Withdrawing from family and friends.
  • Having new friends that they don't want you to meet.

What can you do if you think your teen is using substances?

If your teen is using alcohol, tobacco, or other substances, take it seriously. One of the most important things you can do is to talk openly with your teen. Urge your teen to be open too.

Try not to use harsh, judging words. In most cases, an angry face-to-face meeting will push a teen away. Be as supportive as you can during this time.

If you don't know what to do or if you don't feel comfortable, ask for help. Talk to your teen's doctor, a pediatrician, a psychologist, or a psychiatrist.

Can teen substance use be prevented?

Teens who don't use substances are less likely to have problems with them as adults. Efforts to prevent teen substance use should start early. Start asking about your child's attitudes toward substances in grade school and continue the discussion over time.

To help prevent substance use:

  • Talk to your child from a young age about what you expect. If your teen thinks that you'll allow substance use, they're more likely to try drugs or alcohol. Be prepared for questions about your current or past substance use.
  • Keep your teen busy with meaningful activities, such as sports or other group activities.
  • Expect your teen to follow household rules. Set reasonable consequences for behaviour that needs to change. Then consistently carry out the consequences.
  • Keep talking with your teen. Praise your teen for successes.
  • Know your child's friends. Having friends who avoid tobacco, alcohol, and drugs may be the best protection from substance use.
