Drug Detox | PCP (The Perry Clayman Project)
If you’re reading this page, there’s a good chance that either you or someone close to you is at the point where something needs to change. Drug detox is the clinical process of safely withdrawing from a substance under professional supervision. For most people with a physical dependence, it’s the first step toward getting their life back.
But knowing that detox exists and understanding what it actually involves are two different things. This page walks you through what drug detox looks like in practice and how long it takes, depending on the substance. It also covers when detox becomes medically dangerous and what comes after the physical withdrawal has passed.

Client Testimonials
PCP was very good and the program was explained in depth and i feel good about the future. Andy, he is very passionate to help us and he is very knowledgable about addiction and especially recovery. From his experience we all have learned so much. Amanda is a kind and lovely lady, I have so much respect for her, the staff at PCP work so hard to make us feel safe. I am ready to leave as I have completed 3 months of treatment, I have gained so much and I feel ready to get my life back
Thank you PCPxx
I cannot speak highly enough of the work done at PCP Luton. When my wife entered rehab, we were in a very dark place. We had suffered over a decade of chronic alcohol abuse, and she was declining rapidly. There didn't seem any hope for the future. After 12 weeks of work with Andy, Amanda and all of the staff, she was able to commit to the programme, understand her behaviour and rebuild herself. She has come out a new person, and we now have a future where anything is possible. Thanks, all of you
I have completed 3 months, I came in homeless and a broken man, PCP staff, Andy have helped me get my life back. I have a new home, and I'm 83 days clean and sober, I have tools to help me stay clean and sober. I can't thank PCP enough.
We wanted to write a review as parents, as our son was an addict and went to PCP Luton for his treatment. This has been a traumatic experience for all family members however the professionalism of staff has overwhelmed us enormously and we cannot thank them enough, they've guided us every step of the way their kindness and understanding has been invaluable. Although the participation of treatment was tough we are forever grateful towards the team members. Especially Andy Kalli and Amanda to name a few. They helped us immensely and we couldn`t have done it without them, they have continued to stay in contact with the entire family providing aftercare calls after his departure. The process has been extremely successful and although this has been a life changing experience, we still understand that there must be rigorous and diligent work on his behalf to be completed. We are thrilled and overjoyed to have our loving and exuberant son back, we are extremely obliged and deeply indebted to PCP and we will be forever grateful to the amazing team! Thank you!
I have just completed a 3 month residential programme at PCP and can't thank them enough. I have tried many times to get clean and sober and after spending a short time at PCP last year I decided to check in for 12 weeks. Andy Amanda and the team tailored a programme to suit my needs which included weekly support for my wife and family, helping them to understand addiction and supporting them through the process.
I have attended daily 12 step meetings and have left treatment having completed the 12 steps working with a sponsor. I trusted myself to PCP and had to hand over my care to them and listen to what they were telling me I had to do to stay clean and sober.
What is Drug Detox?
When someone stops using drugs after a period of time, detox is the process of clearing addictive substances or other harmful substances from the body under professional medical supervision. During this period of stabilisation, drug withdrawal symptoms can appear. These symptoms can range anywhere from mild discomfort to serious medical reactions, all depending on the drug in question and how long it has been used for.
While a drug detox can technically be done anywhere, trying to stop cold turkey is strongly discouraged. A medical detox in a clinical environment offers the medical care and medical help needed to manage withdrawal symptoms safely as they develop.
This helps catch any potential complications that could arise and deal with them effectively.

What are the aims of drug detox?
This may seem a little strange to cover because, as most would assume, the sole aim is to remove the substance from the body.
While this is correct, it doesn’t quite cover the full aims of drug detox. The detox process itself is only the first stage of addiction treatment, helping with physical stabilisation before further treatment begins to address the reasons behind substance use.
Essentially, the detox period allows for the substance to be removed from your body, which then gives you the best starting point for a personalised treatment plan that prepares you for the behavioural side of addiction during rehabilitation and longer-term treatment after detox.
You can read more about this distinction in our guide to understanding the difference between detox and rehabilitation.
What happens during inpatient drug detox?
Even contemplating the idea of undergoing inpatient detox can bring a lot of worry into the mix. It’s most likely something you’ve never done before, and that fear of the unknown is enough to put a lot of people off the idea completely, especially when it involves a structured setting with continuous medical support in a supportive environment.
With this in mind, we’ve decided to explain the treatment process in a little more detail than what you’d usually find when researching the detox process.
Assessment
Before the detox procedure can get underway, the clinical team carries out a comprehensive assessment to understand your situation as it stands in that moment. This means questions will cover areas like:
The severity of your dependence
Your substance history, including patterns of drug use
Any other substances you may be using
Any co-existing mental health issues
Your physical health
Any previous detox attempts in the past
Depending on how you answer, this information forms a plan based on your current needs, general health, and withdrawal risks. This includes medications that may be used to help ease uncomfortable symptoms and how long the process lasts.
What your clinical team monitors
Detoxing in a professional environment means you’re looked after every step of the way and to ensure your safety, certain aspects are monitored frequently.
These include:
Vital signs, like heart rate and blood pressure. These are checked regularly because both can change rapidly during the detox period.
Where needed, blood tests may also be used to check physical health and identify any complications.
Withdrawal severity is scored using clinical tools so the team can see whether symptoms are progressing as expected or escalating.
Hydration and nutrition are also monitored, as these can be directly impacted during the detox stage
Sleep is tracked because disruption is common across almost every type of drug withdrawal. Consistent sleep loss affects both physical and psychological recovery.
Your progress is assessed throughout to make sure both physical symptoms and psychological symptoms are managed safely at each stage of withdrawal.
How medications are used during medically assisted detox
The medications used during detox depend on the substance you’re withdrawing from, and the principle behind all of them is to help you through some of the most uncomfortable symptoms during detox.
Below, we briefly explore which medications are used for certain drug detoxes.
Medications like methadone or buprenorphine are used for opioid detox to stabilise your system before being slowly reduced over a set period.1
Medications like diazepam may be given in a reduced dose during alcohol withdrawal to manage the risk of seizures and keep withdrawal symptoms under control. NICE sets out specific steps for this based on the severity of dependence.
Benzodiazepine dependence requires switching to a longer-acting benzodiazepine and tapering over weeks or months, depending on how long you’ve been taking them.3 This is one of the slowest forms of detox because stopping immediately can produce life-threatening seizures.
Stimulant withdrawal doesn’t involve substitute medications because the withdrawal is primarily psychological rather than physical. The clinical focus during stimulant detox is on managing the emotional crash, while supporting you through the period of intense cravings.
Drug withdrawal symptoms to expect during drug detox
We’ve spent a lot of time so far referring to withdrawal symptoms that you may experience during detox, but what do they actually look like? It’s important to be aware because knowing what to expect from the specific drug you’re detoxing from helps you understand why the approach changes so much between substances. Withdrawal symptoms often vary depending on the substance, but many peak within the first few days of detox.
Alcohol
Alcohol withdrawal is one of the most medically serious forms of withdrawal and shouldn’t be underestimated, as it can carry significant health risks and, in severe cases, requires medical detox.
Research describes the early symptoms as:
Anxiety
Headaches
Gastrointestinal discomfort
Insomnia
Alcohol withdrawal can also lead to seizures and dehydration, and symptoms may peak within the first week.
If you’d like to learn more about alcohol detox, there’s more about this on our dedicated alcohol detox page.
Benzodiazepines
Benzodiazepine withdrawal is regarded as one of the most dangerous forms of withdrawal.
Withdrawal symptoms include:
Anxiety
Insomnia
Restlessness
Agitation
Poor concentration
Muscle tension
Benzos must be tapered rather than stopped abruptly, because abrupt cessation can cause life-threatening seizures and other severe withdrawal symptoms, and should not be attempted cold turkey without medical supervision.
Stimulants
Cocaine and amphetamines are stimulants, and detoxing from them works quite differently. Stimulants don’t produce the classic withdrawal syndrome the other drugs do. What happens instead is a post-use crash that is mainly psychological.
Withdrawal symptoms from stimulants include 6:
Fatigue
Depression
Increased appetite
Vivid dreams
Intense cravings
Mood swings
The absence of immediate physical danger doesn’t make stimulant withdrawal safe to face alone. The psychological crash can be severe, and relapse risk during this period runs high.
Opioids
Opioid withdrawal is deeply unpleasant but, in otherwise healthy adults, is rarely directly life-threatening on its own.
The symptoms include:
Muscle aches
Nausea
Vomiting
Diarrhoea
Sweating
Insomnia
- Intense restlessnes
The real danger with opioids comes after detox itself. Your tolerance drops fast during withdrawal, which means that if a relapse does happen, returning to your previous dose carries a serious risk of fatal overdose.
How long does drug detox take?
This is one of the first questions most people ask, and the honest answer is that it depends on the substance and on you as an individual. Detox can last from a few days to two weeks, and many cases typically last around 7 to 10 days.
NICE requires clinicians to account for several personal factors when planning detox duration.6 These include the severity of dependence, any polydrug use, mental health conditions and the medication being used.
That said, the research does give us evidence-based frameworks for what to expect. The table below shows the general timeline for different drug detox programmes by substance type:
Substance | When symptoms start | Peak withdrawal period | Average detox length |
|---|---|---|---|
Alcohol | 6-24 hours after last drink | 48-72 hours | 3-7 days |
Opioids (short-acting) | 8-24 hours | Days 1-3 | 4-10 days |
Opioids (long-acting) | 12-48 hours | Days 3-5 | 10-20 days |
Benzos (short-acting) | 1-2 days | Variable, fluctuating | 2-4 weeks |
Benzos (long-acting) | Up to 1 week | Variable | 2-8 weeks (taper may extend over months) |
Stimulants | 24-48 hours (crash) | Days 3-5 | 7-14 days |
These timelines cover the acute phase, but it’s important to know that a longer, more subtle phase can follow. The WHO clinical guidelines describe protracted withdrawal from opioids lasting up to six months, characterised by low mood and persistent cravings.5
Stimulant cravings and depressed mood can persist for weeks after the acute phase has passed.
This protracted phase doesn’t carry the same medical risk as acute withdrawal, but it’s where a lot of relapses happen. The person feels physically through the worst of it but is still dealing with persistent symptoms that make daily life difficult.
Knowing this phase exists and planning for it is part of what separates a successful detox from one that leads straight back to use.
When is drug detox dangerous?
Not all drug withdrawals carry the same level of medical risk, and understanding which ones are dangerous helps explain why professional supervision exists.
Alcohol
As we can see from our table above, symptoms begin within hours of the last drink, progressing from anxiety and tremors to potential seizures between 8 and 48 hours after cessation.
Withdrawal can progress to delirium tremens in a small percentage of cases, around 3 to 5%. This is a medical emergency involving severe confusion and hallucinations.
This makes it vital for an alcohol detox to take place in a professional environment where withdrawal symptoms can be closely monitored.
Benzodiazepine
Seizures can occur if the drug is stopped abruptly, creating a higher risk of seizures and other serious complications, which is why a managed taper over weeks or months is the standard approach and withdrawal must be medically supervised and managed effectively.
Opioids
Opioid withdrawal can be unpleasant but in otherwise healthy adults is rarely directly life-threatening on its own. The real danger comes after the detox has finished.
Research found that overdose deaths in the year following inpatient opioid detox were clustered among people who had successfully completed the process.8 The cause was loss of tolerance, where their bodies could no longer handle the dose they had previously been used to, and returning to that dose proved fatal.
Stimulants
Stimulant withdrawal doesn’t produce the same medical emergencies as alcohol or benzodiazepines. There are no seizures or cardiovascular instability, but the psychological crash can be severe, with intense depression and high relapse risk during the first few weeks.
Can you detox at home?
The appeal of a home detox is understandable, as you’re in a familiar environment, with your own routine, and the thought of leaving that can add to the anxiety you’re already feeling.
But when you compare what a home detox can offer against what a professional setting provides, the differences are important enough to affect both your safety and your chances of success.
Medical safety
Drug and alcohol withdrawal can produce life-threatening complications that need immediate clinical response. If a seizure happens at home with no medical team present, the outcome can be fatal.
Opioid withdrawal may not carry the same acute medical risk as alcohol or benzos, but the post-detox tolerance drop means that relapse after an unsupervised withdrawal can be fatal.
A professional detox setting provides round-the-clock medical care. A medically supervised detox allows clinical staff to monitor your vital signs and reduce withdrawal symptoms as your body responds. A medically assisted detox also means the team can respond quickly if something unexpected develops.
At home, a complication at 3 AM means dialling 999 and waiting.
The environment you're recovering in
A home detox keeps you in the same environment where your substance use happened. You know where the nearest off-licence is, and you still have the contact details of your dealer.
That kind of access, and a constant source of temptation, can undo days of progress if the cravings become too much. It’s also worth remembering that cravings during acute withdrawal are some of the strongest you’ll experience, meaning it’d be difficult to get through without support, no matter how resilient you are.
A professional setting removes that issue entirely. You can’t act on a craving in the same way when the substance simply isn’t available to you. That barrier alone accounts for a significant difference in completion rates between supervised and unsupervised detox.
The support around you
For people struggling with addiction issues, going through a drug detox can mean losing the coping mechanism they have been relying on.
That means that if unwanted emotions arise, the substance isn’t there to fall back on for comfort.
Anxiety, guilt, grief and emotional rawness are all common during detox and managing these types of feelings without trained support is very difficult.
The team within a professional detox programme understands this fully, which is why therapeutic support is available alongside the medical management side of things.
At home, yes, you may have people around you who care about you, but they’re not equipped to handle the psychological side of drug detox, and a professional setting offers a stronger support network throughout the process.
Treatment after detox has finished
Once you’ve completed the detox stage, the next step is further treatment aimed at building long-term recovery by identifying the reasons behind the addiction. A lot of people struggle to put their finger on exactly where their addiction came from, which makes this next stage crucial for recovery.
Post-detox treatment involves therapies such as cognitive behavioural therapy and DBT, as well as group therapy, to help you identify the thinking patterns that keep the addiction firmly in control.
Once you identify these disruptive thinking patterns, you’re then able to challenge and change them moving forward.
If trauma or underlying mental health conditions are driving the addiction, this is something that will be addressed during therapy. Ongoing therapy is essential for maintaining sobriety post-detox.
Relapse prevention is also another core part of treatment after detox has finished. These types of sessions will give you the blueprints needed to manage the situations that lead you back to using again. Many programmes offer 12 months of free aftercare services and help you build coping strategies for a healthier future.
Access to support groups and ongoing contact with a keyworker are also part of what makes the transition from detox to daily life manageable. Clinically managed residential detox often relies on peer support and structure, and slower detoxification methods may help prevent immediate relapse.
Managing the stress of this period is a real challenge, and our guide on tips for effective stress management during the detox period covers practical strategies that can help.
