Warning Signs of Substance Use in Teens

If your teen seems withdrawn, secretive or is suddenly struggling in school, those changes could point to substance use. Recognizing the signs early gives you a better chance of getting them connected with the right help and support.

Here's what to watch for and how to know when it's time to take action.

Behavioral Signs of Teen Drug Use

You know your teen best. When something feels off, trust your instincts. These behavioral changes could signal teen addiction symptoms.

Common Red Flags

• Avoiding eye contact or locking bedroom doors
• Withdrawing from family and longtime friends
• Ignoring curfews or breaking household rules
• Frequently asking for money without explanation
• Lying about whereabouts or making secretive calls
• Losing interest in school, sports or hobbies
• Slipping grades or skipping class

While these shifts may seem like "just a phase," if they start to stack up, they could point to something deeper.

Physical Signs to Watch For

Substance use often shows up in a teen's appearance and physical health. If you're noticing changes that don't have a clear explanation, take note.

Possible Physical Symptoms

• Bloodshot or glazed eyes
• Frequent nosebleeds or runny nose
• Sudden weight loss or gain
• Shaking hands, cold sweats or extreme fatigue
• Wearing long sleeves to hide marks
• Puffy face or sores around the mouth

When these symptoms appear alongside behavioral changes, it's time to take action.

Typical Teen Behavior vs. Signs of Substance Use

Mood swings, secrecy and pushing boundaries can be part of growing up. But when these behaviors become extreme, persistent or are paired with physical symptoms, they may indicate a deeper issue.

Ask yourself:

• Are these changes sudden and intense?
• Do they interfere with daily life, school or relationships?
• Are they accompanied by physical health concerns?

If the answer is yes to more than one, it's worth exploring further.

Risk Factors for Teen Substance Abuse

Some teens are more vulnerable to addiction due to risk factors identified by researchers, including:

• Family history of substance use
• Early exposure to alcohol or drugs
• Cravings and tolerance that build quickly in developing brains
• Surroundings that normalize risky behavior

Peer pressure and casual experimentation can escalate things quickly, especially when substance use is portrayed as harmless or glamorous in media. That's why early conversations and early support matter.

How to Talk with Your Teen

Start with empathy. Teens are more likely to open up when they feel safe, not judged. Try:

• "I've noticed some changes, and I'm worried. Can we talk?"
• Listening without interrupting
• Avoiding lectures or accusations
• Sharing your values and expectations calmly

You don't need to have all the answers. You just need to show up with care and consistency.
