Relapse means going back to drinking or drug use after a period of stopping. It is common: the US National Institute on Drug Abuse (NIDA) puts relapse rates for drug addiction at 40 to 60 per cent, similar to the rates for high blood pressure and asthma. A relapse means treatment needs to be restarted or changed, and it does not cancel the progress made. If the person has used opioids such as heroin after a break, the risk of overdose is higher than before, so if they are hard to wake or struggling to breathe, call 999.
What relapse means
In addiction, relapse is a return to the old pattern of use after a period of recovery. Some researchers split it in two: a lapse, often called a slip, is the first drink or use, and a relapse is a return to uncontrolled use.
The difference matters because a slip that is dealt with quickly often stays a slip. It still needs taking seriously, since one drink or one use can quickly lead back to uncontrolled use. The best response is honesty: tell someone the same day and call whoever is treating the person.
In Malaysia, the National Anti-Drugs Agency (AADK) uses the term "penagih berulang", a repeat case. In August 2025 its deputy director-general said about 20 per cent of drug users in the country are classed this way after treatment. That figure and NIDA's measure different things in different groups, so they cannot be compared directly.
How common relapse is
Addiction is a chronic illness, one that lasts and needs managing over time. NIDA compares its relapse rate with other chronic illnesses:
- Drug addiction: 40 to 60 per cent relapse
- Type 1 diabetes: 30 to 50 per cent
- High blood pressure: 50 to 70 per cent
- Asthma: 50 to 70 per cent
NIDA's guide says relapse is "not only possible but also likely", as it is when asthma symptoms return, and it is a sign to look again at the treatment.
The warning signs come first
A relapse rarely starts with the drink or the drug. A 2015 review on relapse prevention in the Yale Journal of Biology and Medicine describes it as a gradual process that can begin weeks or months earlier, in stages.
The first stage is emotional: the person is not thinking about using, but is looking after themselves less well. Signs include:
- Bottling up feelings and pulling away from people
- Missing support meetings or appointments, or going but not talking
- Focusing on other people's problems instead of their own
- Poor eating and sleeping
The second stage is mental: part of them wants to use and part does not. Signs include:
- Cravings, and thinking about the people and places tied to past use
- Talking about past use as if it was mostly fun, or playing down what it cost
- Bargaining, such as "only at weekends" or "just one beer"
- Lying, and looking for a chance to use
Families often notice these before the person admits them. Saying calmly what you have seen at this stage is far easier than dealing with a full relapse later.
The overdose risk after a break
After weeks or months without a drug, in rehab, in prison or at home, the body loses its tolerance, the adjustment that made a regular user need more for the same effect. The dose they used to take can now be enough to stop their breathing.
The World Health Organization (WHO) lists going back to opioids after a period of not using, such as after detox or stopping treatment, as a risk factor for overdose. People leaving prison have very high rates of overdose in their first four weeks out. Mixing opioids with alcohol or sedatives such as sleeping pills raises the risk further.
The WHO describes three signs of opioid overdose:
- Very small, pinpoint pupils
- Being unconscious or impossible to wake
- Difficulty breathing
If you see these, call 999 immediately. WHO also recommends that naloxone, a medicine that reverses an opioid overdose, be available to families and friends of people who use opioids. Ask the doctor treating the person whether this is possible for you.
Alcohol has its own risk. A person who returns to heavy daily drinking and then stops suddenly can go into dangerous withdrawal. Our guide to alcohol withdrawal explains when that becomes an emergency.
The first days: for the person
- If you have used opioids after a break, do not use alone, and do not mix them with alcohol or sleeping pills.
- Tell someone you trust today. Hiding a slip is what usually turns it into a relapse.
- Call your doctor, counsellor or treatment centre, and use your aftercare plan if you have one.
- Get rid of what you have, and stay away from the people and places tied to use for now.
- Eat, sleep and keep a basic routine. The reminder HALT stands for hungry, angry, lonely and tired: try not to let any of them build up.
- Write down what happened in the days before, as the start of a better plan.
The first days: for the family
- Check that they are safe. If they cannot be woken, are breathing strangely or are confused, call 999.
- Stay calm. Shouting and shame tend to push use out of sight, and you need it in the open.
- Wait until they are sober to talk. Then say what you have seen and ask what help they will accept.
- Call their treatment team, or a service like ours, for advice, even if they will not.

Relapse prevention planning
A relapse prevention plan is written with a clinician and says what to do before and after things start to slip. A good one includes:
- The person's own early warning signs, in their words
- Their high-risk situations: people, places, times, moods, paydays
- What they will do instead when a craving comes
- Names and numbers of people to call, day and night
- What the family has agreed to do if they notice warning signs
- What happens if there is a slip
Support groups help too. NIDA's guide says peer support during and after treatment can help people stay off drugs, and the Yale review notes that joining a self-help group raises the chances of long-term recovery.
Aftercare
Aftercare is the support that continues after a residential programme: sessions, check-ins, support groups and family work. NIDA's guide says continuing care, adjusted as needs change, gives many patients the best results. It also says that treatment of less than 90 days, residential or outpatient, has limited effect, which is why we work to 90 days.
Going back to treatment is not failure
Many families fear a second admission means the first was wasted. NIDA's guide says recovery is a long-term process that often takes more than one episode of treatment, and lapses "do not indicate failure". They show that treatment needs to be restarted, adjusted or changed, and a second stay can build on what the person learnt in the first.
Common questions
What does relapse mean in addiction?
Relapse means going back to drinking or drug use after a period of stopping, usually to the old, uncontrolled pattern. A single episode is called a lapse or slip. Both are reasons to get support quickly.
How do I help someone with a drug relapse?
Check they are safe, and call 999 if they cannot be woken or are struggling to breathe. Talk calmly once they are sober, avoid blame, and contact their treatment team or a service that can advise you. You do not need their agreement to ask for advice.
What should I do after a relapse?
Tell someone you trust, contact the people treating you, and remove access to alcohol or drugs. If you used opioids after a break, do not use alone, because your tolerance is lower.
Can relapse be prevented?
Not always, but the risk can be lowered with a written relapse prevention plan, aftercare, support groups and a family that knows the warning signs.
