How to Talk to a Friend Who Might Be Using Cocaine

You’ve noticed things you can’t unnotice. The way they disappear at parties. The way Sundays have become impossible to schedule with them. The little change in their face that you can’t quite name. The fact that you’ve thought about this article enough times to actually search for it.

If you’ve found this page, you already know.

This is a guide to having the conversation. Not an intervention. Not a confrontation. An actual conversation, with a person you care about, in a way that has any chance of helping rather than pushing them further away. It is written from years of clinical and lived-experience evidence about what works and what doesn’t.

We’re going to cover: how to know if you’re seeing what you think you’re seeing, how to prepare yourself, what to say, what absolutely not to say, what to expect when you bring it up, and what to do if they minimise it (most people will, at first).

No moralising. No “you must intervene”. No clichés. Just the honest map.

TL;DR: the three things that work and the three that fail

1-on-1, in private, when both of you are sober

Bringing it up in front of others, especially in a group

Talking about what you’ve noticed using “I” statements

Telling them what they are (“you’re an addict”)

Asking, not telling. Listening, not advising.

Giving advice they didn’t ask for

Coming back after a “no”

Demanding action in one conversation

The single biggest mistake people make: trying to solve it in one conversation. You can’t. The goal of the first conversation is just to open a door and prove that you can be trusted with the truth.

First: are you actually seeing what you think you’re seeing?

Before you have any conversation, it’s worth being honest with yourself about whether you have real reason to be concerned or whether you’re pattern-matching from a film you saw.

Signs that someone may be using cocaine regularly, that show up consistently in clinical literature:

• Disappearances in social situations. Repeatedly going to the bathroom in pairs at parties. Long absences with no explanation.
• The Sunday pattern. Unreachable, exhausted, or in bed for the whole day, week after week.
• Money issues that don’t add up. Borrowing more than they used to, vague about where it goes, expensive habits without the income to match.
• Sleep changes. Wired late into the night, then crashing for entire days. Hard to make morning plans.
• Personality shifts when drinking. Becoming a sharper, faster, more talkative version of themselves around their second drink in a way that didn’t used to be there.
• Defensive about questions. Conversations about their week or weekend become evasive. Subject changes feel deliberate.
• Physical signs. Frequent runny nose without a cold, occasional nosebleeds, weight loss, dark circles, jaw tension when sober.
• Group chat patterns. Specific friends, specific times, specific 4am energy in messages.

You do not need all of these to be concerned. A persistent feeling of “something is off” with someone you’ve known for years is usually a real signal.

What does not count as evidence:

• Someone using once at a party
• Someone you’ve heard rumours about secondhand
• Someone who fits a stereotype you have in your head
• One bad night or one rough Sunday

The question is pattern, not incident.

Before you have the conversation: get yourself ready

The most common mistake people make is having this conversation when they’re upset, frightened, or angry. The conversation will go badly. They will mirror your state. You will both leave hurt.

Before you bring it up:

Get clear on your own feelings. Are you worried for them, angry at them, hurt by something specific, or some combination? Naming this for yourself first means you won’t deliver all three emotions at once into a conversation that needs only one.

Get clear on what you actually want from the conversation. Almost always, the realistic answer is: I want them to know I’ve noticed and that I’m here whenever they’re ready to talk. That is enough. That is the entire goal of the first conversation.

Get clear on what you cannot do. You cannot make someone in active use decide to stop. You cannot rescue them. You cannot care more about their recovery than they do, and if you try, you will burn out before they’re ready. This sounds harsh and it is the kindest realistic frame.

Pick the right time. Not at a party. Not after work when they’re tired. Not when either of you has been drinking. Not via text. Walking together, driving together, or sitting somewhere private without time pressure is best.

Don’t tell anyone else you’re going to do it. Their privacy is part of the trust. If they find out you discussed them with a third party before talking to them, the trust is gone before the conversation begins.

The wrong way to bring it up

These patterns push people away. Avoid them.

The intervention. Pop-culture interventions (a group of people confronting someone together) have a poor evidence base in actual clinical literature, and they’re devastating to the relationship. Skip the group format entirely.

The accusation. “I know you’ve been using.” Even if you do know, this puts them in a defensive position immediately. They lie. They escalate. They leave.

The diagnosis. “I think you’re an addict.” Don’t label them. This is a word they have to be ready to apply to themselves. Coming from someone else, it almost always lands as an attack.

The ultimatum. “Either you stop or I’m done.” Sometimes the threat is real and necessary. But if your goal is the relationship continuing, ultimatums in early conversations almost always backfire. Save them for later, if at all.

The advice they didn’t ask for. “You need to see a therapist.” “Have you tried AA?” “Just stop.” You don’t know what they’ve already tried. You don’t know what they’re capable of right now. Unsolicited advice is heard as criticism.

The reading list. Don’t lead with articles or links, even this one. People feel ambushed when a sentence arrives with a URL. Talk first. Resources later.

The public hint. Don’t post about it on social media in coded ways they’ll recognise. Don’t make pointed comments at gatherings. Don’t bring it up “lightly” in front of mutual friends. They will know exactly what you’re doing.

The right way: how to actually do it

The shape that works best, in clinical literature and in lived experience, is roughly this:

Start by saying you care about them. Not as preamble, as the actual frame. “I love you and I want to ask you something difficult. I’m not trying to corner you and I won’t be upset if you don’t want to talk about it.”

Talk about what you’ve noticed, using “I” statements. “I’ve noticed you’ve been tired on Sundays for a long time.” Not “You’ve been a wreck on Sundays.” The first is observation. The second is judgement.

Ask a real question and then let there be silence. “Is everything okay?” or “How are you really doing?” Then stop talking. Let the silence sit. Most people fill silences with the truth.

If they minimise (most will), don’t push back. “I’m fine” is almost always the first response. That’s okay. The conversation is not over because they said it. The conversation is over because you accepted the door is closed for today. The door isn’t gone. It’s just closed.

Tell them you’re here when they’re ready. “Okay. I just wanted you to know I’ve noticed and that whenever you want to talk, I’m not going to judge you and I won’t tell anyone.”

End with something that isn’t about the topic. “Anyway, do you want to grab something to eat?” Normalise the relationship after. The conversation should not feel like an event that changes everything. It should feel like one moment in a continuing friendship.

That’s the entire script. It takes about six minutes. It doesn’t solve anything, and it doesn’t have to. It opens a door, and that is the whole job.

5 sentences that work and 5 that don’t

These land:

1. “I love you. I want to ask you something and you don’t have to answer.”
2. “I’ve noticed [specific thing] and I wanted to check you’re okay.”
3. “You don’t have to talk about anything you don’t want to. I just wanted you to know I’m here.”
4. “Whatever you’re going through, I’m not going to judge you and I won’t tell anyone.”
5. “What do you need from me right now, if anything?”

These don’t:

1. “I know what you’re doing.”
2. “You need to stop.”
3. “This is destroying you, can’t you see?”
4. “My cousin had the same problem and she…”
5. “If you don’t get help, I can’t be in your life.”

The sentences that work share a property: they offer something. The sentences that don’t share a property: they demand something.

What to expect when you have the conversation

Most people, the first time someone close to them brings up their substance use, will respond in one of four ways:

Minimisation. “I’m fine. It’s just weekends. Everyone does it.”

This is the most common response and it usually doesn’t mean they don’t know it’s a problem. It means they’re not ready to admit it to you specifically yet. Don’t argue. Accept the door is closed for today. Make sure they know it can open later.

Anger. “What are you saying? You don’t know anything about my life.”

Anger usually means you’ve hit a nerve they’re not ready to look at. Don’t escalate. Apologise for the timing, not for the question. “I’m sorry if this felt like an attack. That’s not what I wanted. I just love you and I noticed.” Then back off.

Deflection. “Yeah, things have been hard. Work has been brutal.”

They’re acknowledging something but not the substance use itself. That’s actually progress. You don’t have to push for the rest. Let them tell you whatever feels safe to tell.

Acknowledgement. “Yeah. I know.”

If this happens, you’ve earned trust most people never get. Your job in this moment is not to fix anything. Your job is to listen and to ask what they need.

What almost never happens in the first conversation: the person announces they’re ready to quit and asks for your help with a recovery plan. If this happens, great. But don’t expect it, and don’t measure success by whether it happens.

What to do if they say no

If they minimise or deflect, your part of the work is mostly done for now. The conversation existed. They know you noticed. They know they can come back to it.

The hardest part of being the concerned friend is accepting that you cannot speed up someone else’s readiness. Recovery has its own clock. The most influential predictor of when someone enters recovery is not how many people confronted them. It is whether they have at least one person in their life who they trust to know, without judgement.

That person is now you.

Things to do quietly, after a “no”:

• Stay in the friendship. Don’t withdraw as punishment. That would teach them that being honest costs them you.
• Make space for casual contact. A walk, a coffee, a normal weekend hang. Recovery readiness often emerges in unstructured time, not in dramatic moments.
• Keep the door open. Once in a while, maybe twice a year, you can gently re-mention it. “How are you doing with everything?” No need to be more specific than that.
• Look after yourself. Worry is exhausting. Don’t disappear into it. Your stability is one of the things they may need to lean on later.

What to do if they say yes

If they acknowledge it, your only job is to listen. Not to solve. Not to recommend. Not to call a clinic. Just listen.

Then, when they ask what to do (if they ask), here are the gentle resources you can share:

• The NHS Frank service: 0300 123 6600, confidential, no judgement, available 24/7
• Their GP: still the most reliable starting point for any kind of substance use treatment in the UK
• NHS adult substance use services: free, available across the UK, can be self-referred without going through GP in most areas
• Clarity: the UK recovery app built for cocaine, alcohol, and stimulant recovery. AI companion at 2am, craving tools, no waitlist, free to start.

You don’t have to share all of these. Share whichever feels most natural for the moment. If they’re not ready for a GP visit, an app is a low-friction first step.

For context on what their recovery may look like once they’re ready, the cocaine withdrawal timeline maps the day-by-day reality of stopping. If you have ADHD in your family, our cocaine and ADHD article covers why some people with ADHD end up here first. Both of these are useful for you to understand, not necessarily to send to them.

A low-friction first step they can take alone

If they’re not ready for a GP visit, Clarity is the UK recovery app built for that exact moment. Private, no email signup, no waitlist. An AI companion at 2am, craving tools, and a place to put the question down for a few days and see what they actually think. Free to start.

In crisis call 999 or FRANK 0300 123 6600.

When to step back

Some situations are beyond the scope of a friend-led conversation. Step back, get professional support, and protect yourself if:

• They are using in ways that pose acute health risks (combining with alcohol heavily, using daily, chest pains, signs of psychosis)
• They are putting children at risk
• Their use is causing them to act in ways that endanger you or others
• They have already told you to stop bringing it up
• You are losing your own mental health in trying to support theirs

In those cases, you may need to involve professionals or social services. That is not betraying them. That is recognising the limits of friendship.

Confidential support for you, as the concerned person, is also available through:

• Adfam (adfam.org.uk): UK charity supporting families and friends of people affected by drugs and alcohol
• Al-Anon UK: meetings for friends and family of people with substance use issues
• DrugFAM: 0300 888 3853, helpline specifically for families affected by addiction

You are allowed to have your own support without that meaning anything bad about your friend.

A note on your own feelings

If you’ve read this far, it’s because someone you love is in trouble and you don’t know what to do. That is one of the most exhausting positions in human life. Watching someone you care about hurt themselves, when you can’t fix it, is uniquely painful.

You are allowed to be angry. You are allowed to be sad. You are allowed to be tired of carrying the weight of something that isn’t yours. You are allowed to maintain boundaries that protect you while still loving them. None of these things are betrayals.

The most useful thing you can be for someone in active addiction is a stable, predictable, non-judgemental presence in their life. Not their therapist. Not their saviour. Just there. That is the role that recovery research consistently identifies as the single biggest external predictor of eventual recovery.

You don’t have to fix it. You just have to stay.

If you’ve been told you might have a problem

A different audience read this far: people who searched this query because someone has already had the conversation with them, and you want to understand what they were trying to say.

If that’s you: the fact that someone you trust brought this up is information. It doesn’t make them right about every detail. But it usually means a pattern has become visible from outside that you have been managing quietly from inside.

You don’t owe anyone a specific response. You don’t have to declare yourself anything you’re not ready to declare. But you might quietly explore what your own answer would be if you weren’t performing it for anyone.

Clarity is built for exactly this moment. Private, no signup beyond the app, no GP visit, no waitlist. Just a place to put the question down for a few days and see what you actually think.
