Understanding What Your Friend Is Going Through

You’ve noticed something’s changed with your friend. Maybe they’re missing school more often, their grades have dropped, or they just seem different—more withdrawn, irritable, or secretive. Perhaps you’ve seen them drinking or using drugs, and you’re worried. The truth is, watching someone you care about struggle with substance use is one of the hardest experiences you can go through as a teenager. You want to help, but you might feel confused, scared, or unsure about what to do.

First, know this: your concern shows how much you care, and that matters more than you realize. While you can’t force someone to change or fix their problems for them, you can be a positive presence in their life during an incredibly difficult time. Understanding what substance use disorder really is—and what it isn’t—will help you support your friend more effectively.

Substance use disorder isn’t about being weak or making bad choices. It’s a medical condition that affects the brain’s reward system, making it extremely difficult for someone to stop using even when they want to. When someone uses substances repeatedly, their brain chemistry actually changes, creating powerful cravings and making normal activities feel less rewarding. This means your friend isn’t choosing drugs or alcohol over you—they’re dealing with something that’s hijacked their brain’s normal functioning.

Recognizing the Signs That Someone Needs Help

Before you can support your friend, it helps to recognize what you’re actually seeing. Substance use exists on a spectrum, from occasional experimentation to serious dependency, and the signs can vary widely depending on where someone falls on that spectrum.

Physical signs might include bloodshot eyes, sudden weight changes, unusual smells on their clothes or breath, frequent nosebleeds, or changes in their sleep patterns. You might notice they’re always tired or, conversely, seem wired and unable to sit still. Their appearance might change—they might stop caring about hygiene or dressing well when they used to take pride in how they looked.

Behavioral changes are often more obvious. Your friend might become secretive, lying about where they’ve been or who they’re hanging out with. They might drop their old friend group entirely and start spending time with a completely different crowd. Their priorities shift—activities they used to love, whether that’s sports, music, art, or hanging out with you, suddenly don’t seem to matter anymore.

Emotional and psychological signs can be subtle but significant. Mood swings, increased irritability, anxiety, or depression might all be present. Your friend might seem paranoid or defensive when you ask simple questions. They might laugh off concerns or get angry when you express worry about their behavior.

Academic and social consequences usually follow. Grades drop, sometimes dramatically. They might skip classes, stop doing homework, or even drop out of activities or sports they once excelled in. Conflicts with family members often increase, and you might hear about arguments or tension at home.

What You Can Do: Practical Ways to Support Your Friend

Supporting a friend through substance use challenges requires a delicate balance. You want to be there for them without enabling their behavior or putting yourself in harmful situations. Here’s how you can walk that line effectively.

Start by educating yourself about substance use and addiction. Understanding that this is a medical condition, not a moral failing, will help you approach your friend with compassion rather than judgment. Learn about the specific substances your friend is using if you know what they are. Different substances have different effects and risks, and understanding these can help you recognize warning signs of serious danger.

Choose the right time and place for a conversation. Don’t try to talk to your friend when they’re high or drunk—they won’t be able to have a meaningful conversation, and it might even be dangerous. Instead, find a quiet, private moment when they’re sober. Make sure you have enough time to talk without being rushed.

When you do talk, use “I” statements instead of “you” accusations. Say things like “I’ve noticed you seem different lately, and I’m worried about you” rather than “You’re messing up your life.” This approach feels less like an attack and more like genuine concern. Be specific about what you’ve observed: “I’ve noticed you’ve missed school three times this week” is more effective than “You’re always absent now.”

Listen more than you talk. Your friend might open up about what they’re going through, or they might get defensive. Either way, give them space to express themselves. Don’t interrupt, don’t judge, and don’t try to immediately solve their problems. Sometimes people just need to feel heard.

Set boundaries for yourself. This is crucial. You can care about your friend without sacrificing your own wellbeing or safety. Don’t cover for them, don’t help them hide their substance use, and don’t put yourself in situations where you might get in trouble or be unsafe. It’s okay to say, “I care about you, but I can’t be around you when you’re using.”

Encourage professional help without being pushy. Let your friend know that treatment works and that getting help is a sign of strength, not weakness. Professional treatment provides medical supervision, therapy, and support systems that friends and family simply can’t offer on their own. For example, medical supervision is essential during withdrawal from certain substances like alcohol or benzodiazepines, where stopping suddenly can actually be life-threatening. Detox Treatment Programs in Portland and similar facilities across the country offer safe, supervised environments where people can begin their recovery journey with proper medical care, counseling, and support—moving from initial detox through ongoing treatment in a compassionate setting that feels less like a hospital and more like a place of healing.

What Not to Do: Avoiding Common Mistakes

With the best intentions, it’s easy to make mistakes when trying to help a friend with substance use issues. Understanding what doesn’t work can be just as important as knowing what does.

Don’t enable their behavior. This means not making excuses for them, not covering for them with parents or teachers, and not giving them money (which they might use to buy substances). Enabling might feel like you’re being a good friend, but you’re actually making it easier for them to continue using without facing consequences.

Avoid lecturing or preaching. Your friend already knows that substance use is harmful—they don’t need another lecture. Approaching them with judgment or superiority will only push them away and make them less likely to open up to you in the future.

Don’t try to be their therapist or doctor. You’re their friend, and that’s a valuable role, but it’s not the same as being a trained professional. Substance use disorder requires professional treatment, especially when it’s serious. Thinking you can fix this on your own isn’t just unrealistic—it can be dangerous.

Never use substances with them thinking it will help you understand them better or keep them safer. This logic is flawed and dangerous. You can’t help your friend by putting yourself at risk, and using with them only normalizes the behavior.

Don’t give up on them if they’re not ready to change. Recovery is rarely a straight line. Your friend might reject help multiple times before they’re ready to accept it. While you need to maintain your boundaries, letting them know you still care—even if you can’t be around them while they’re using—can make a difference down the road.

Taking Care of Yourself While Supporting Others

Supporting a friend through substance use struggles can take a serious toll on your own mental health. You might feel anxious, sad, frustrated, or even angry. You might feel guilty, wondering if there’s something more you could have done or should be doing. These feelings are completely normal, but they also signal that you need to take care of yourself.

Talk to a trusted adult. This might be a parent, school counselor, coach, teacher, or other mentor. You don’t have to handle this alone, and getting guidance from someone with more life experience can be incredibly helpful. If your friend is in immediate danger—showing signs of overdose, talking about suicide, or engaging in seriously risky behavior—tell an adult immediately. This isn’t betraying your friend; it’s potentially saving their life.

Consider joining a support group. Al-Anon and Alateen are programs specifically designed for friends and family members of people struggling with substance use. These groups provide a space where you can share your experiences with others who truly understand what you’re going through. You’ll learn coping strategies and realize you’re not alone in this experience.

Maintain your own activities and friendships. Don’t let your friend’s struggles consume your entire life. Continue participating in activities you enjoy, spending time with other friends, and focusing on your own goals and wellbeing. You can’t pour from an empty cup—taking care of yourself makes you better able to support others.

Set emotional boundaries, not just physical ones. It’s okay to limit how much you take on emotionally. You can care about your friend without carrying the weight of their recovery on your shoulders. Their choices are ultimately their own, and their recovery journey is theirs to walk—you can be supportive without being responsible for the outcome.

Understanding the Path to Recovery

If your friend does decide to seek help, understanding what recovery looks like can help you be more supportive throughout the process. Recovery isn’t a single event—it’s a journey that typically involves several stages and can take months or even years.

The first step is often acknowledgment—recognizing that there’s a problem and that help is needed. This can be the hardest step because it requires overcoming denial and facing some difficult truths. If your friend reaches this point, it’s a huge deal, even if they’re scared or uncertain about what comes next.

Medical detox is often necessary, especially for substances like alcohol, opioids, or benzodiazepines. This is where the body clears the substance while under medical supervision. Withdrawal can be uncomfortable and, in some cases, dangerous, which is why professional medical care is so important during this phase. Detox typically lasts several days to a week or more, depending on the substance and the severity of use.

Treatment programs come in various forms and intensities. Residential or inpatient treatment involves staying at a facility full-time, usually for 30, 60, or 90 days. Partial hospitalization programs allow someone to receive intensive treatment during the day while returning home at night. Outpatient programs involve attending treatment sessions several times a week while living at home and potentially returning to school or work.

Therapy is a core component of recovery. Individual counseling helps people understand the root causes of their substance use, develop coping strategies, and work through underlying issues like trauma, depression, or anxiety. Group therapy provides peer support and helps people realize they’re not alone in their struggles. Family therapy can help repair relationships and teach family members how to support recovery.

Medication-assisted treatment may be part of the recovery plan, especially for opioid use disorder. Medications like buprenorphine or naltrexone can help reduce cravings and prevent relapse while someone works on the psychological and behavioral aspects of recovery. This isn’t replacing one drug with another—it’s using medicine as a tool to support recovery, just like someone with diabetes uses insulin.

Aftercare and ongoing support are critical for long-term success. This might include continuing therapy, attending support group meetings like Alcoholics Anonymous or Narcotics Anonymous, staying connected with a sponsor or mentor, and building a sober support network. Recovery is a lifelong process, and having ongoing support dramatically increases the chances of maintaining sobriety.

When Your Friend Relapses

Relapse—returning to substance use after a period of sobriety—is common in recovery. Studies show that 40-60% of people in recovery experience relapse at some point, which is similar to relapse rates for other chronic conditions like diabetes or hypertension. If your friend relapses, it doesn’t mean treatment failed or that they’re hopeless. It means they need to adjust their recovery plan and try again.

If your friend relapses, avoid expressing disappointment or anger, even though you might feel those emotions. Instead, express concern and remind them that relapse doesn’t erase the progress they’ve made. Encourage them to reach out to their treatment team, therapist, or sponsor immediately. The faster they get back on track, the less likely the relapse is to spiral into a full return to active addiction.

Help them identify what triggered the relapse if they’re willing to talk about it. Was it stress? Being in a certain environment? Spending time with people who use? Understanding triggers helps them develop better coping strategies going forward. Remind them that many people who eventually achieve long-term recovery experienced relapses along the way—it’s often part of the learning process.

Hope for the Future

Recovery is possible. Millions of people have overcome substance use disorders and gone on to live healthy, fulfilling lives. Treatment works, especially when it includes medical care, therapy, and ongoing support. Your friend’s struggle doesn’t define them, and their current situation doesn’t determine their future.

Your role as a supportive friend matters more than you might realize. Even if your friend isn’t ready to change right now, knowing that someone cares about them and believes in their ability to recover can plant a seed that eventually grows into motivation for change. Sometimes the kindest thing you said or did won’t show results for months or even years, but that doesn’t mean it didn’t matter.

Remember that you’re not alone in this either. Countless other teenagers are watching friends struggle with substance use, feeling the same confusion and worry you’re experiencing. Reaching out for support—whether from adults, counselors, or support groups—isn’t a sign of weakness. It’s a sign that you’re mature enough to recognize when you need help, just like you’re hoping your friend will eventually do the same.

Keep showing up with compassion, maintain your boundaries, take care of yourself, and hold onto hope. Your friend’s recovery journey is ultimately theirs to walk, but knowing you’re there—believing in them even when they can’t believe in themselves—can make all the difference.
