Start Your Recovery with Safe Drug Detox

When someone is addicted to drugs and wishes to overcome addiction, detoxification is a necessary first step towards recovery.
Detoxification, also known as detox, is the process of clearing the body of substances, such as drugs and alcohol, and managing any withdrawal symptoms that occur1 . This part of recovery sets the stage for therapy by ensuring that you are physically and emotionally fit and ready.
The drug detox process can seem daunting if you have become dependent on substances, but don’t let it become a hurdle in your recovery. Additionally, different medications and drugs carry unique risks–and can be dangerous to stop suddenly or on your own.
The most effective form of detox or withdrawal management is one that is medically supervised and supported by trained professionals, as it ensures the best–and safest– outcomes for your recovery.
At Castle Craig, we prioritise the safety and comfort of our patients, doing our best to support them from detox through to aftercare.

Why Professional Drug Detox Is Necessary

Psychological and physical drug addiction can be difficult to manage on your own. The main goal of professional medical detox treatment is to ease the discomfort of withdrawal from drugs.
Drug withdrawal symptoms encompass a variety of physical risks and psychological challenges. These risks and challenges depend on the type of substance used, level of dependence and duration of misuse, but there are some common symptoms. 1
What are the Physical Withdrawal Symptoms from Drug Detox?
Common drug withdrawal symptoms include nausea and vomiting, aches and pains, difficulty sleeping and diarrhoea. However, the body adapts to the long-term presence of a drug, so severe drug withdrawal can occur during detox. The physical risks of severe withdrawal include:
- Raised blood pressure, heart rate and/or breathing rate
- Seizures
- Heart problems
- Respiratory issues.
According to the World Health Organisation (WHO), medically managed treatment is important during detox to help manage these physical risks and prevent loss of life.
What are the Psychological Withdrawal Symptoms from Drug Detox?
Common psychological symptoms and signs associated with drug withdrawal include1 :
- Fatigue
- Depression
- Anxiety
- Panic attacks
- Restlessness, irritability or agitation
- Difficulty concentrating
- Mood swings
- Intense cravings.
Aside from these symptoms, more severe psychological withdrawal symptoms such as paranoia, hallucinations and psychosis can occur. In such cases, patients may be transferred to hospital for specialist care. 1
These psychological challenges, while perhaps not as life-threatening as physical ones, pose a major problem as they can derail the recovery process by reducing motivation.
If you’ve decided to seek help, opting for treatment in a rehab facility may improve your chances of successful recovery. The physical risks of withdrawal symptoms can be dangerous and sudden, while the psychological challenges of withdrawal can offset your recovery.
Attempting to detox by yourself at home may lead to:
- Increased risk of relapse and overdose
- Lack of access to prescription medications or substitution treatments
- Lack of medical support and professional guidance.
Medically managed drug detox delivers emotional support, reduces physical discomfort and mitigates relapse and overdose risks.

Drug Detox Process and Timeline
One of the first questions many patients ask is, “How long does drug detox take?”.
The answer to this question depends on the substance used, how long it was used for and the level of dependence. The duration of detox can also be affected by a person’s motivation and their access to support and professional help. Typically, the detoxification process takes between a few days and a number of weeks to complete. 3
Medical detox at Castle Craig begins with a one-to-one assessment to determine the best course of treatment for you and your unique circumstances.
Once an appropriate course of action has been discussed and implemented, you may start to experience the effects of acute withdrawal. Acute withdrawal includes physical withdrawal symptoms and can be followed by signs of post-acute psychological withdrawal. In a professional detox setting, appropriately controlled medications may be given to help you cope with acute and post-acute withdrawal effects.
If acute and post-acute withdrawal isn’t carried out in a supervised setting, it can have dangerous health consequences or increase the chances of relapse.4
Research has shown that supportive care, engagement in social aspects of recovery and exposure to role models during the recovery journey can promote sustained abstinence.5 Professional medical detoxes offer consistent emotional and medical support and can present opportunities for engaging in aftercare activities following the withdrawal process.
Types of Drug Detox
Professional detoxification treatment can differ depending on the specific addictive drugs. Distinct substances can affect the body and mind in unique ways, so can present certain challenges during the withdrawal process.
Castle Craig specialises in delivering expert care and support during detoxification. We provide personalised, comprehensive approaches to detox and treatment which promote lasting sobriety. Our experienced teams provide medically supervised detox to support recovery from a range of drug addictions.

Cannabis Detox and Withdrawal Symptoms
Detoxifying from cannabis is not typically life-threatening, but it can be a challenging process for people who are dependent on it.
Eliminating cannabis metabolites from the body can take several days to a couple of weeks, depending on physical dependence and heaviness of use. The early stages of cannabis withdrawal include symptoms such as headaches and gastrointestinal discomfort.
However, the psychological withdrawal symptoms of cannabis can persist for several weeks. These symptoms include intense drug cravings, mood changes, sleep disturbances, and restlessness, amongst others.
Attempting to detox from cannabis at home can pose challenges due to the unpleasant effects of withdrawal and access to the drug. Castle Craig’s cannabis detox treatment programmes can provide a secure and comfortable environment to support you during the withdrawal period.

Cocaine Detox and Withdrawal Symptoms
When people choose to detox from cocaine, it takes time for their brains to adjust before delivering ‘feel-good’ chemicals again.
Cocaine detox may pose less physical risk than some other illicit drugs, but a ‘cocaine crash’ can cause psychological overwhelm and emotional damage. Common symptoms of psychological withdrawal include intense cravings, depression, anxiety, irritability and sleep disturbances, amongst other issues.
A medically supervised detox may therefore be the safest option for people looking to overcome addiction to cocaine. Cocaine detox at Castle Craig provides understanding, empathy and 24/7 medical monitoring to support patients on their unique journey to recovery.

Heroin Detox and Withdrawal Symptoms
As heroin is a short-acting opioid drug, acute withdrawal symptoms can happen quickly and suddenly. Physical opioid withdrawal symptoms can be highly unpleasant, but with appropriate withdrawal management, they should not be life-threatening.
Heroin withdrawal can cause pain and discomfort and is often referred to as being similar to a severe flu. In severe cases, there is the risk of delirium and seizures. The psychological symptoms of heroin detox include intense cravings, anxiety, depression, irritability, insomnia and inability to concentrate or make decisions.
Depending on the level of physical dependence, these post-acute withdrawal symptoms can last for periods up to months, and without professional management, they increase the risk of relapse–or even overdose.
Castle Craig’s heroin withdrawal treatments can provide assistance and support for anyone considering heroin detox.

Benzodiazepine Detox and Withdrawal Symptoms
Benzodiazepines can be short or long-acting drugs. Short-acting benzodiazepine withdrawal can start several hours after stopping the drug. However, long-acting benzodiazepine withdrawal can take up to three weeks to start.
Physical withdrawal symptoms of benzodiazepines include nausea, stomach cramps, sweating, loss of appetite, headaches, dizziness, sensitivity to light and sound, blurry vision and tinnitus. Severe, potentially life-threatening, withdrawal symptoms from benzodiazepine detox include seizures, delirium tremens (DTs) and coma.
Psychological withdrawal symptoms of benzodiazepines include anxiety, depression, panic attacks, irritability, decision-making difficulties and insomnia.
Suddenly stopping benzodiazepines can be dangerous. Professional benzodiazepine detox helps to gradually reduce the drug from the body in a medically managed tapering process. This process reduces the risk of complications during withdrawal, promoting the best possible outcomes for patients. (1)
Castle Craig’s benzodiazepine detoxification programme offers professional support to anyone hoping to overcome benzodiazepine addiction.
