Signs of Teen Drug Use

December 14, 2024

If you’re the parent of a teen, you have good reason to be concerned about your teen using drugs. According to a 2023 survey, 10.9% of eighth graders, 19.8% of 10th graders, and 31.2% of 12th graders reported illicit drug use in the past year. Even more frightening is that drug overdose deaths among teens are rising.

As a parent, you need to be vigilant about observing your teen and understanding what signs might indicate that your teen is using drugs. If you suspect that they’re using, you can take action to protect your child by getting them the help that they need.

Personality and Mood Changes

While it’s not unusual for teens to exhibit personality changes or mood swings, they can sometimes be an indicator of a mental health disorder or drug use, both of which require intervention. Some signs to look for include:

  • Suddenly seeming withdrawn or depressed
  • Lack of motivation
  • Hostility or anger
  • Lying or being secretive
  • Lack of focus
  • Unusually happy or manic
  • Sudden mood swings
  • Defensiveness

Any of these can be normal for adolescents, but they warrant a conversation with your teen to try to uncover the cause.

Changes in Behavior

The most notable signs of potential drug use are significant changes in behavior. These may include:

  • Ditching old friendships and hanging out with a new crowd
  • Disappearing for long periods of time
  • Disinterest in family activities or spending time at home
  • Ignoring rules like curfew
  • Missing school
  • Behavior problems at school
  • Avoiding eye contact
  • Locking the door to their room
  • Being secretive with their cell phone use
  • Using mints or gum to cover their breath
  • Shortness of cash
  • Using eye drops for red eyes
  • Sleeping for long periods of time
  • Stealing money or prescription medications from family members

Appearance

Sometimes teens who are using drugs change in appearance, often not taking care of themselves as they should, or experiencing physical changes from the drug use. Some signs include:

  • Lack of hygiene
  • Unkempt appearance
  • Smelling of smoke or other unknown substances
  • Flushed cheeks
  • Track marks (note that they may try to hide these with long sleeves)

Health Signs

Drug use obviously can affect the health of your teen. You might notice:

  • Stumbling or clumsiness
  • Slurred speech
  • Frequent illnesses
  • Unusual fatigue
  • Nosebleeds
  • Sores or spots around the mouth or on other parts of the body (some drugs like meth can lead to scratching and picking)
  • Sudden weight loss or gain
  • Abrasions or bruises
  • Sweating
  • Vomiting
  • Seizures

If you notice any of these signs in your teen, make an appointment with your child’s doctor or seek emergency medical care for more serious symptoms.

Don’t Hesitate to Search

While you may be hesitant to invade your teen’s privacy, finding out if they are using drugs can be a matter of life and death. You should search their room looking for drugs, paraphernalia, or other evidence that suggests drug use. Leave no stone unturned.

Common hiding places may include:

  • In drawers under other items
  • Small containers like makeup bags or earbud holders
  • Under the bed or other furniture
  • Inside books
  • Inside medication containers like aspirin bottles
  • In food or beverage containers like chip bags or soda cans

You should also check their phone, which can be a prime source of information. Look for conversations that hint of drug use or purchases, or evidence that they’ve lied about where they’ve been. Check both texts and social media messages.

What To Do If You Suspect Drug Use

If you know or believe that your teen is using drugs, the first rule is don’t get angry. If you confront your child with angry accusations, they will likely either get defensive or shut down.

Instead, find a time to sit down and have a non-judgmental conversation with them. Ask them questions about what drugs they are using, if their friends use drugs, and most importantly, why they are using drugs. They may be using them to cope with anxiety or depression, or they may have felt pressure from friends to use.

Approach these questions with love and concern, and don’t punish them. You should, however, set expectations about their behavior. You can do things like having them check in with you when they’re with friends and allowing you to track their location with their phone.

You should also make an appointment for them with their doctor, who can evaluate their health, both physically and mentally, and refer you to resources for assessment and treatment if necessary. NEMG can also provide you with these resources.

A full substance abuse disorder assessment will determine if your teen is just experimenting, or if they need treatment, and if so, what course of treatment they require. The assessment will also uncover any co-occurring mental health disorders, such as anxiety or depression, that will require treatment as well.

In Closing

Discovering that your teen is using drugs is frightening, but you need to be observant and look for the signs. The sooner you know, the sooner you can intervene and get your child the help that they need. With treatment and your support, your teen can go on to live a healthy and fulfilling life.
