Signs of Drug Use: How to Help Someone You Love

Worry makes ordinary details feel like evidence. A locked phone, an empty bank account or a week of bad sleep can suddenly look like the missing piece of a frightening puzzle. Sometimes drug use is involved. Sometimes the real explanation is depression, debt, medication, grief, an unsafe relationship, a physical illness—or simply a person who is having an awful month.

The safest response is neither to ignore everything nor to play detective. Deal with an emergency first. Then separate facts from guesses, choose a calm moment and talk about the effect of what is happening. You can help somebody reach support, but you cannot force an adult to admit a problem or recover on your timetable.

This is a UK guide for adults worried about a partner, relative, friend or older child. It explains possible signs, what carries more weight than appearance, how to start the conversation, how to set boundaries and where each UK nation directs people for help. It cannot tell you which substance somebody has taken or provide a diagnosis.

Call 999 now when it may be an overdose

While you wait for the ambulance

1. Check for danger. Do not put yourself in danger from traffic, violence, fumes, powders or needles.
2. Check response and breathing. Speak loudly and gently shake their shoulders if it is safe to do so. Look for normal breathing.
3. Follow the 999 call handler. Put the phone on speaker if you can. Their instructions take priority over an online article.
4. Use the recovery position if they are unconscious but breathing. This helps keep the airway open and reduces the chance of choking.
5. Start CPR if they are unresponsive and not breathing normally. The call handler can guide you. Gasping is not normal breathing.
6. Stay and keep checking. Tell paramedics about changes and show them packaging, containers or medicines if these can be handled safely.

Do not give them coffee, food, water or a cold shower. Do not make them walk around and do not try to make them vomit. Do not assume that “sleeping it off” is safe. If you are unsure whether a swallowed, inhaled or touched substance is harmful and there are no emergency symptoms, call NHS 111 for advice.

If an opioid overdose is possible and naloxone is available

Naloxone temporarily reverses the breathing problems caused by heroin and other opioids, including methadone, morphine, fentanyl and nitazenes. It does not replace an ambulance. Call 999, use the product exactly as supplied or as you were trained, follow the call handler and stay with the person. Tell paramedics how much naloxone was given and when.

A family member or friend of somebody at risk may be able to obtain take-home naloxone from a local drug service, pharmacy or another authorised service; arrangements vary locally. Government guidance says anyone can use available naloxone to save a life in an emergency. Ask a service for the correct product training rather than trying to remember instructions from social media.

Mental health can also be an emergency

Call 999 or go to A&E if somebody’s life is at risk, they have seriously harmed themselves, taken an overdose or you cannot keep them or somebody else safe. In England, NHS 111 has a mental health option for urgent help that is not an immediate life-threatening emergency. The route differs elsewhere in the UK, so use the local NHS service or emergency department.

What do “signs of drug use” actually mean?

They mean possible clues, not a home diagnosis. Red eyes may come from allergies. Weight change may follow illness. Missing money may be debt, gambling or coercion. Irritability may be pain, poor sleep or a mental health problem. Teenagers can become private and change friendship groups without taking drugs.

The question is not “Can I match three symptoms to a list?” It is “What has changed, how often is it happening, is there a clear explanation, and is anybody unsafe?” A cluster of changes that is new, persistent and disrupting daily life deserves a conversation even when drugs are not the cause.

Use a pattern, not a stereotype

There is no single look, job, age or family type that reveals drug use. Somebody can be neat, employed and affectionate while still struggling. Somebody can also look tired, disorganised or withdrawn without using any drugs. Photographs of pupils, skin, teeth or weight cannot identify a substance reliably.

Write down a few concrete events if your thoughts are racing: “did not come home on Tuesday”, “nearly fell asleep while cooking” and “asked to borrow £150 after payday” are observations. “Has become an addict” is a conclusion. Start the conversation with observations.

Possible behavioural, practical and physical changes

The groups below can help you organise what you have seen. None is proof by itself, and a sudden medical change should be assessed on its own merits rather than blamed on drugs.

Changes in routines and responsibilities

• repeatedly missing work, education, appointments or family commitments;
• sleeping at very different times or staying awake for unusually long periods;
• dropping hobbies and relationships that used to matter;
• taking unusual risks, including driving when they may be impaired;
• letting food, hygiene, childcare or home safety slide;
• frequent short disappearances without a workable explanation;
• problems that keep recurring despite apologies and plans to change.

Money, medicines and secrecy

• borrowing more often, selling belongings or missing essential bills;
• cash withdrawals or transfers they will not discuss when finances are shared;
• prescriptions running out much earlier than expected;
• visiting several prescribers or giving changing accounts of lost medicine;
• missing medicines from another person’s supply;
• packages, powders, tablets, pipes, scorched foil, small bags or needles that have no clear explanation.

Objects can increase concern, but do not handle an unknown powder, used needle or unlabelled substance. Keep children and pets away and ask an appropriate local service for disposal advice. Do not taste, smell, burn or flush an unknown substance.

Mood, thinking and relationships

• uncharacteristic agitation, drowsiness, confusion or suspiciousness;
• rapid swings between energy and exhaustion;
• more arguments, isolation or missed contact;
• difficulty concentrating, remembering or following a conversation;
• using a substance to cope with sleep, pain, anxiety or difficult feelings;
• becoming distressed or angry when a substance or medicine is unavailable.

These changes also occur with mental illness and physical illness. For example, a parent struggling after a birth may need the kind of urgent and practical support covered in our guide to postnatal depression signs and partner support. If pregnancy is part of the picture, our pregnancy anxiety guide explains when to contact a midwife, GP or urgent service. Do not use a drug suspicion to dismiss another health need.

Physical changes

Changes can include unusual sleepiness, restlessness, sweating, shaking, nausea, appetite change, unsteady movement, slurred speech, red eyes or pupils that look different. The same signs can come from prescribed medicines or an acute medical problem. Do not try to name the drug from one feature. If the change is sudden, severe or accompanied by breathing problems, collapse, seizure, chest pain, very high temperature or extreme confusion, get urgent medical help.

Signs that use may be becoming dependent or harmful

A stronger concern comes from what the person says and what repeated use is doing to their life—not whether they “look like” somebody with an addiction. The NHS describes addiction as losing control over doing, taking or using something to the point that it may be harmful.

Patterns that carry more weight

• using very regularly or spending a great deal of time obtaining, using or recovering;
• trying to cut down or stop and being unable to do so;
• continuing despite clear harm to health, relationships, work, education, money or safety;
• needing more to get a similar effect, or using to avoid feeling unwell;
• giving up important activities because use gets in the way;
• using alone, in dangerous situations or while responsible for a child;
• concealing the amount or taking extreme steps to obtain drugs or medicines;
• recognising a problem but feeling frightened or unable to change.

These are reasons for a professional assessment, not labels to throw during an argument. A person does not need to hit “rock bottom” or lose everything before they can ask for help.

Physical dependence is not the whole story

The body can adapt to some prescribed medicines even when they are taken as directed. That may cause withdrawal symptoms if the medicine is stopped suddenly, but it does not by itself prove compulsive or harmful use. Equally, somebody can have harmful use without obvious physical withdrawal. A GP, prescriber or drug service can assess the medicine, dose, reason for use and wider pattern.

Do not improvise a home detox

Encouraging somebody to throw everything away tonight can sound decisive, but abrupt withdrawal from some substances or medicines can be dangerous. Help them speak to a GP, prescriber, pharmacist or drug treatment service about a safe plan. If they are acutely unwell, use 111 or 999 as appropriate.

How to start a conversation without turning it into a trial

Talk when you are both sober, in a private and familiar place, with enough time to listen. If they have previously threatened or hurt you, choose safety over privacy: speak to a domestic abuse service, have support nearby or do not confront them in person. Immediate danger means 999.

Prepare three things

1. Two or three observations: dates and events, not a dossier covering every flaw they have ever had.
2. The effect: what has become unsafe or difficult for them, you or the children.
3. One offer: sit with them while they call a GP, FRANK or a local service; give them a lift; or watch the children during an appointment.

Words you can actually use

• “I care about you. I’ve noticed you missed work twice and nearly fell asleep while cooking. What is going on?”
• “I might be wrong about the reason. I’m not wrong that you seem unwell and the children were frightened.”
• “Are you using anything—including prescriptions or drugs—that I should know about to help keep you safe?”
• “What feels hardest at the moment?”
• “Would you rather call the GP, contact the local drug service directly or ring FRANK together?”
• “I can listen without arguing. I cannot let you drive the children when you may be impaired.”

Listen for the problem underneath the argument

Some people use drugs to cope with pain, trauma, anxiety, loneliness, sleep or pressure from others. Understanding the reason does not make unsafe behaviour acceptable, but it helps identify useful support. Ask open questions, allow silence and repeat back what you heard. You do not need to agree with every explanation to keep the conversation respectful.

What tends to close the door

• starting while they are intoxicated, withdrawing or already furious;
• using names such as “junkie”, “addict” or “liar” as the whole argument;
• inviting a crowd to surprise or shame them;
• threatening consequences you cannot or will not carry out;
• demanding an instant promise of lifelong abstinence;
• treating a shop-bought drug test as a complete medical assessment;
• making children question, watch or report on the adult.

Talking with a teenager

Normal adolescent changes are not proof of drug use. Choose a calm moment, explain the specific safety concern, listen and avoid a dramatic interrogation. Ask what they know, what their friends are doing and whether anything has made them feel pressured or unsafe. Be clear about driving, school, medicines and what may enter the home.

Digital privacy and safety can become part of this without turning every message into evidence. Our calm online-safety guide explains how to keep communication open while acting on an immediate risk. FRANK also has specific advice for parents and carers worried about a child.

What if they deny it or refuse help?

You may be mistaken about drugs. Or you may be right and still hear “nothing is wrong”. Do not spend hours trying to win an admission. Return to facts and safety: “I hear that you say you are not using. I still need us to deal with the missed rent and unsafe driving.”

You cannot force a capable adult into an honest conversation or ordinary community treatment. You can keep the offer open, ask a service for advice yourself and act when children, driving, violence, money or the home are unsafe. If the first conversation goes badly but nobody is in immediate danger, pause and try again later.

Boundaries that protect without pretending you control them

A boundary describes what you will do. “You must never use again” attempts to control somebody else. “I will not lend money, and I will pay the electricity company directly if I decide to help with that bill” is a boundary you can keep.

Keep important documents, medicines, keys and money secure if you are worried about safety. Tell one trusted person what is happening. If there is coercion, intimidation or violence, this is not merely a “drug problem”; use the relevant domestic abuse and police support. The government’s UK support page lists nation-specific helplines, and immediate danger always means 999.

When children live in the home

A child should not have to supervise an intoxicated adult, clear up substances, hide the problem, miss school to provide care or decide when an overdose is serious. Make sure there is a sober adult responsible for meals, school, medicines, transport and bedtime. Lock away medicines and substances, keep emergency numbers available and agree where the child can go if the home becomes frightening.

If a child is in immediate danger, call 999. If you think a child may be at risk of abuse or neglect, contact the children’s social care team at the relevant local council or authority; you do not have to prove abuse before sharing a genuine concern. The GOV.UK reporting service explains routes across England, Wales, Scotland and Northern Ireland and lists the NSPCC adult helpline on 0808 800 5000.

Do not promise a child secrecy that could leave them unsafe. Explain, in simple words, that the adult’s behaviour is not the child’s fault and that you may need to tell another safe grown-up. Preserve ordinary routines where you can. The ideas in our guide to making family life calmer at home can help with routines, but they do not replace safeguarding action.

Where to get drug and family support in the UK

A person who wants help can start with a GP or contact a local drug treatment service directly. Family and friends can ask for support even when the person using drugs refuses treatment. That matters: you do not have to wait for somebody else to change before getting advice about safety, money, children or your own wellbeing.

FRANK for confidential information

FRANK’s helpline is 0300 123 6600 and operates 24 hours a day. Its contact page also lists text service 82111 and support in multiple languages. You can call because you are worried about somebody else; you do not need to know exactly which drug is involved.

Support for you, not only for the person using drugs

The NHS lists family support organisations including Adfam, Addiction Family Support, Families Anonymous, SMART Family and Friends and Release. Different approaches suit different people. You might want a local group, a confidential helpline, practical legal advice or one-to-one support. Try another route if the first feels too formal or does not fit your family.

What treatment may involve

Community treatment is not automatically residential rehabilitation. At a first appointment, a service usually asks about substances, health, mental health, housing, work and family, then agrees a plan. The NHS says people seeking help for a drug problem are entitled to treatment like anybody else with a health problem.

Depending on the person and substance, a plan may include:

• a named keyworker and regular appointments;
• talking therapies and help with triggers, routines and relationships;
• medicines such as methadone or buprenorphine for some opioid dependence;
• a clinically planned detox when appropriate;
• physical and mental health checks, including infection testing where relevant;
• needle and syringe services, overdose advice and naloxone;
• peer or self-help groups;
• support with housing, benefits, work or family needs;
• inpatient or residential care when the assessment shows it is needed.

There is no honest promise that one conversation, detox or stay in rehabilitation will permanently solve everything. Recovery can include setbacks. A useful service should treat the person respectfully, explain privacy and consent, discuss how family may be involved and offer family members an assessment of their own needs. NICE specifically recommends support for families and carers, including information, guided self-help and family meetings where appropriate.

When comparing private care, searches may surface treatment center drug abuse resources and provider pages about drug abuse. These examples describe one Las Vegas provider, so treat them as information about that organisation—not independent proof or a UK referral route. Check location, clinical oversight, safeguarding, total fees, aftercare and what happens if the person leaves early; UK readers can start with the NHS and local services above.

Questions to ask a service

• Can the person self-refer, and how quickly will they be assessed?
• What happens while they wait?
• How will physical health, mental health and prescribed medicines be reviewed?
• What is the plan for overdose risk and naloxone?
• How can family be involved with the person’s consent?
• What support is available to children, partners and carers in their own right?
• Who should we contact if risk changes suddenly?

Look after your own safety and health

Living with uncertainty can shrink life to checking phones, counting money and waiting for the next crisis. Get help for yourself even if the person says you are overreacting. A GP can discuss sleep, anxiety and local family support. A specialist family organisation can help you think through boundaries without demanding an immediate decision about the whole relationship.

Do not carry this alone. Tell a trusted person, protect access to essential money, keep a note of serious incidents and make a plan for children and pets. If you are frightened of a partner or family member, use domestic abuse support rather than arranging a private confrontation. Seeking support is not betraying them; it is recognising that their choices are affecting more than one person.

A simple plan for today and the next week

Common questions about signs of drug use

What are the first signs that somebody may be using drugs?

There is no reliable universal first sign. Concern usually comes from a new pattern across routines, money, relationships, health or safety. One change—such as tiredness, red eyes or secrecy—has many possible causes and does not prove drug use.

Can you tell which drug someone has taken from their eyes or behaviour?

No. Some substances can affect pupils, alertness, speech and co-ordination, but so can medicines and medical emergencies. Do not use appearance to identify a drug. Ask what they took if it is safe, keep packaging for paramedics and seek urgent help for severe symptoms.

Should I confront somebody if I suspect drug use?

Have a calm conversation rather than a confrontation. Choose a sober, private moment, describe specific observations, listen and offer practical help. If you fear violence or coercion, do not confront them alone; seek specialist safety advice.

What should I say?

Try: “I care about you. I have noticed these specific changes and I am worried. I may be wrong about the cause, so can you tell me what is happening?” Follow with one offer, such as calling a GP, local drug service or FRANK together.

Can I make an adult go to rehabilitation?

Usually you cannot force a capable adult into ordinary treatment, and residential rehabilitation is not the only option. You can offer help, ask a service for family advice, set safety boundaries and use emergency, safeguarding or mental health routes when the legal threshold is met.

Should I give money so they do not buy drugs in a more dangerous way?

You do not have to provide cash. If you choose to help with essentials, consider paying a provider directly or buying food while also getting specialist advice. Protect shared finances and do not put yourself or children at risk.

What should I do with drugs or needles I find?

Keep children and pets away. Do not touch a used needle with bare hands or taste, smell, burn or flush an unknown substance. Ask the local council, pharmacy, police non-emergency service or drug service for safe disposal advice. Call 999 if there is immediate danger.

When should I call 999?

Call if somebody cannot be woken, is not breathing normally, has severe difficulty breathing, has a seizure, may have taken an overdose, has seriously harmed themselves or you cannot keep somebody safe. Follow the call handler and stay with them.

What is naloxone?

Naloxone is an emergency antidote that temporarily reverses breathing problems caused by an opioid overdose. Call 999 even when it works. Family and friends may be able to obtain a kit and training from a local drug service, pharmacy or authorised provider.

Can family get help if the person refuses treatment?

Yes. NHS and nation-specific services list help for relatives and friends, and Northern Ireland’s official guidance explicitly says support is available even if the person using substances is not in treatment. A GP or family organisation can also help you plan boundaries and support your wellbeing.

Is drug dependence treatable?

Yes. Treatment can include a keyworker, talking therapies, medicines for some opioid dependence, planned detox, harm reduction and support with health and daily life. The right mix depends on the person and substance.

What if the signs are really a mental or physical health problem?

That is possible, which is why observations and medical assessment matter more than guessing. Ask about their health and encourage a GP or appropriate service. Use 111 or 999 for urgent symptoms rather than assuming drugs are the cause.

The bottom line

Possible signs of drug use are a reason to check safety and begin a conversation—not a licence to diagnose somebody from their eyes, mood or bank balance. In an emergency, call 999 and follow first-aid instructions. Outside an emergency, use specific observations, listen, offer one practical route to help and set boundaries you can genuinely keep.

Support is available for families even when the person is not ready. Start with a GP, local drug service, FRANK or the nation-specific route above. Then make the home safer today: protect children, driving, medicines and essential money. You do not need to solve the rest of somebody’s life before taking that useful first step.
