Spotting changes early, starting a non-judgemental conversation and involving trusted adults can help teenagers support a friend while protecting their own wellbeing.
Helping a friend whose drinking or drug use has become worrying can leave teenagers feeling torn between loyalty and alarm. The first step is to understand that substance use rarely comes from nowhere. Johns Hopkins Medicine says addiction can involve a loss of control over use, along with physical and psychological signs that disrupt daily life. For adolescents, that vulnerability is shaped by development as well as circumstance: the brain’s prefrontal cortex, which helps with judgement and impulse control, is still maturing well into the mid-twenties, according to Sobriety Navigator, while National Institutes of Health research has linked early substance use with differences in adolescent brain structure.
That does not make the behaviour less serious, but it can help explain why compassion matters. NewYork-Presbyterian says people struggling with substance use often respond to fear, shame or stress with defensiveness, anger or withdrawal, which can make honest conversation harder. The point is not to excuse harmful choices, but to avoid turning concern into judgement. A young person may be dealing with trauma, pressure at school, family instability or mental health problems that are invisible to friends.
Noticing the warning signs early can make a real difference. Johns Hopkins Medicine and Grand Valley State University both point to changes in behaviour, mood and daily functioning as common indicators that use may be becoming a problem. A friend may skip activities, drift away from other friendships, become secretive, show shifts in sleep or appearance, or struggle at school. They may also become irritable, flat, anxious or unusually defensive. If a teenager begins asking for money frequently, selling possessions or borrowing without explanation, that can also be a sign that something deeper is going on.
If you decide to speak up, preparation matters. The CDC recommends planning what you want to say and even practising it beforehand, especially if the topic feels intimidating. It can help to begin during a calm moment, perhaps while doing something together, and to keep the first conversation simple. Phrases that focus on what you have noticed, such as changes in mood or attendance, are more likely to land than accusations. Johns Hopkins Medicine advises choosing a private setting, staying non-judgemental and being ready for a range of reactions, including denial.
Listening is just as important as speaking. Grand Valley State University recommends being direct but supportive, and reminding a friend of their good qualities can make it easier for them to accept help. If they open up, resist the urge to lecture or interrogate. The goal is to show that you care enough to notice, not to force an immediate confession or solution. If they deny there is a problem, the CDC suggests staying steady and checking in again later rather than treating one conversation as the end of the matter.
Real support also means knowing where the line is between helping and enabling. That can mean refusing to lend money if you suspect it will be used for substances, declining to cover up absences or lies, and not joining in with drinking or drug use in the hope of keeping the other person safe. It also means encouraging professional support. Depending on the situation, that may include counselling, outpatient treatment, residential care or a support group. Treatment is not one-size-fits-all, and some people need a more structured setting than others.
At the same time, the friend offering support needs boundaries of their own. You cannot control whether someone decides to get help, and trying to do so can quickly become exhausting. It is reasonable to step back from conversations that become unsafe or emotionally overwhelming, and to keep up your own routines, schoolwork and friendships. That is not abandonment. It is a recognition that one teenager cannot carry another person’s recovery on their own.
Support from adults can be essential, especially when a situation becomes serious. Trusted parents, school counsellors, coaches or other mentors can help with perspective and resources. There are also programmes such as Al-Anon and Alateen for people affected by someone else’s drinking or drug use. If there is any sign of overdose, emergency help should come first: call 911, stay with the person and be ready to use naloxone if opioids are involved and the medication is available. If a friend talks about suicide or immediate self-harm, urgent intervention is necessary. In that moment, secrecy is less important than safety.
