Recognizing the Signs
Addiction does not always look the way media portrays it. A classmate struggling with substance use may still attend classes, participate in activities, and maintain a social life — at least initially. However, patterns often emerge over time that signal something deeper is going on.
Behavioral Changes to Watch For
Common indicators include a noticeable decline in academic performance or attendance, withdrawal from activities, clubs, or friend groups they previously enjoyed, changes in peer groups — particularly gravitating toward others known for substance use, increased secrecy about whereabouts and activities, mood swings, irritability, or uncharacteristic emotional outbursts, changes in physical appearance or hygiene, borrowing money frequently or financial difficulties, and missing belongings or unexplained expenses.
Physical Signs
Physical indicators may include bloodshot or glassy eyes, unexplained weight loss or gain, frequent illness or complaints of feeling unwell, unusual smells on clothing or breath, slurred speech or impaired coordination, and changes in sleep patterns.
How to Approach the Conversation
Choosing the Right Time and Place
Have the conversation in a private, comfortable setting where your classmate does not feel ambushed or embarrassed. Avoid bringing up concerns when either of you is rushed, in a group setting, or when your classmate appears to be under the influence.
Using Compassionate Language
Frame your concerns using "I" statements that express care rather than accusations. For example, say "I have noticed you seem different lately and I am worried about you" rather than "You have a drug problem." Focus on specific observations and your feelings rather than labels or diagnoses.
What Not to Do
Avoid issuing ultimatums, shaming, lecturing, or trying to force change. Do not attempt to be their therapist or take responsibility for their recovery. Do not cover for them by doing their homework, making excuses, or hiding their substance use from others — this enabling behavior, though well-intentioned, can delay their recognition that they need help.
Resources Available
School-Based Support
Most schools and universities have resources including guidance counselors and school social workers, student health and wellness centers, peer counseling programs, and student assistance programs (SAPs). These professionals are trained to handle substance use concerns confidentially and can connect students with appropriate services.
Crisis Resources
If you believe a classmate is in immediate danger — from overdose, suicidal ideation, or a medical emergency — call 911. For non-emergency situations, the SAMHSA National Helpline (1-800-662-4357) provides free, confidential, 24/7 referrals and information.
Taking Care of Yourself
Supporting someone through addiction is emotionally demanding. Maintain your own boundaries, continue engaging in your own activities and relationships, and seek support from trusted adults or counselors if the situation is affecting your own well-being. You cannot pour from an empty cup, and your mental health matters too.
Frequently Asked Questions
Should I tell a teacher or counselor even if my classmate asked me not to?
If you believe your classmate is in danger, yes. Safety takes priority over secrecy. Most school counselors can handle referrals discreetly and are trained to approach the student with sensitivity. You may feel like you are betraying trust, but connecting someone with help can save their life.
What if my classmate denies having a problem?
Denial is common in addiction. If your classmate is not ready to acknowledge their struggles, you cannot force them. Express your concern, let them know you are available, and leave the door open. Sometimes it takes multiple conversations before someone is ready to accept help.
Can I get in trouble for reporting a classmate's drug use?
Most schools have policies designed to protect students who report substance use concerns, and many have medical amnesty policies. The goal is getting help, not punishment. Check your school's specific policies if you are uncertain.
