Personalised Detox Treatment Plans
Castle Craig provides medically managed drug and alcohol detox in a safe residential setting, where every drug and alcohol treatment plan is tailored to the patient. We offer full detoxification under 24-hour medical care, delivered by an experienced and compassionate medical team. Our evidence-based therapies are combined with a whole-person approach to recovery, all set within peaceful surroundings rich in nature and wildlife, far removed from the triggers of daily life.
While most people need only a short-term detox lasting a few days, some may require a longer stay depending on their health, substance use and personal circumstances. This article will explain what a longer detox might involve, including how a 21-day detox, a 28-day detox and a 30-day detox process work. You will also find details on the benefits of sustained inpatient care, typical long-term detox costs and what to expect when choosing a month-long withdrawal management programme. To learn more about our medically managed 4-week addiction rehab treatment with detox in the Scottish Borders, call 01721 546 263 today.
What is a Long-Term Detoxification Programme?
A long-term detoxification programme is a clinic-based process where people with drug or alcohol dependence receive medical support over several weeks. Unlike shorter detox options, it provides more time for stabilisation, strengthening of physical health and the introduction of therapy alongside medical care.
Examples of longer treatment options include a 21-day detox, a 28-day detox or a 30-day detox. Extended detox timeframes allow patients more space to withdraw safely, regain stability and begin addiction counselling. They can benefit from sustained support that helps them transition into the next stages of substance addiction treatment.

Common Substances That May Need Month-Long Detox
The length of drug or alcohol detox varies greatly depending on the individual, the substance involved, the severity of addiction and other health factors. Some people may complete withdrawal in less time, while others require longer medical supervision. Below are examples of substances where healthcare experts often recommend extended detox timeframes.
-
Alcohol 21-Day Detox and Long-Term Residential Rehab Support
A 21-day detox for alcohol allows patients to withdraw under close medical care while supporting their physical and emotional health. Extended supervision can help manage cravings, stabilise mood and improve overall well-being before moving into alcohol rehab therapy.
Long-term residential rehabilitation support is often recommended following a 3-week alcohol detox. At Castle Craig, evidence-based therapies are combined with complementary approaches to help patients address triggers, strengthen coping strategies and sustain recovery beyond the alcohol detox phase.
-
28-Day Benzo Detox Clinic and Multi-Week Withdrawal Treatment
A 28-day benzodiazepine detox clinic offers patients structured medical support to manage the challenges of tapering off medications. The longer timeframe helps reduce risks such as seizures, anxiety, and rebound insomnia during benzodiazepine withdrawal.
Castle Craig provides multi-week withdrawal treatment for benzodiazepines, where medical stabilisation is paired with addiction counselling and whole-person care. This combination helps patients safely transition from detox into ongoing recovery within a residential rehab setting.
-
Opioid 30-Day Drug Detox and Ongoing Inpatient Addiction Care
A month-long drug detox may be advised for people dependent on opioids such as heroin. Extended medical care supports safe withdrawal while addressing severe cravings and physical symptoms that can persist for weeks.
Ongoing inpatient addiction programmes following 30-day opioid detox give patients access to psychological therapies and structured support. Continued drug rehab treatment helps build stability and reduce the likelihood of relapse following detoxification.
-
Prescription Painkiller 3-Week Detox and Prolonged Rehab Support
A 3-week detox for prescription painkillers allows time for gradual withdrawal under medical supervision. This reduces the risk of complications while giving patients the opportunity to recover strength and health in a safe environment.
Prolonged drug rehab support is recommended after detox from prescribed medications, where therapy and structured care address the psychological dependence linked to painkillers. Longer treatment durations can help patients adjust to life without medication while building resilience.
-
Month-Long Stimulant Detox and Sustained Residential Treatment
Month-long detox for stimulant dependence can help people struggling with substances such as cocaine or amphetamines. Extended medical monitoring supports recovery from fatigue, mood instability and sleep disturbance that often follow stimulant withdrawal.
At Castle Craig, sustained residential addiction treatment combines detox with therapies that address the psychological impact of stimulant use. Our integrated approach supports long-term stability and helps patients develop healthier coping mechanisms.
-
Extended Cannabis Inpatient Detox and In-Depth Aftercare
Extended inpatient detox for cannabis may be required when people experience persistent withdrawal symptoms such as anxiety, irritability or insomnia. A longer detox provides medical and therapeutic support to help patients adjust more comfortably.
An in-depth aftercare programme following cannabis detox can provide therapy, relapse prevention strategies and community-based support. This sustained care helps individuals maintain abstinence and develop healthier routines over the long term.
-
Synthetic Drug One-Month Detox and Intensive Withdrawal Care
Synthetic drugs, including psychoactive substances, can produce unpredictable withdrawal symptoms. A one-month detox treatment allows for close monitoring, helping to manage both physical effects and mental health challenges during recovery.
Intensive drug withdrawal care following detox may involve therapy, medical oversight and ongoing inpatient rehab treatment. Longer treatment pathways give patients the chance to regain stability and manage the unpredictable risks linked with synthetic substances.

21-Day Drug and Alcohol Detox Process
A 21-day detox gives patients more time to withdraw from substances safely while restoring health and stability. This extended approach helps manage withdrawal more effectively and prepares people for the next stage of drug or alcohol rehab treatment.
- Thorough clinical evaluation and extended detox planning: Patients undergo a full medical and psychological review, allowing clinicians to create a safe three-week detox plan suited to their health and substance history.
- Ongoing medical supervision with continuous nursing care: Nursing staff provide round-the-clock support, monitoring symptoms and responding quickly to changes while helping patients feel safe during long-term detox.
- Specialist use of medications to manage and reduce withdrawal effects: Where appropriate, doctors prescribe carefully chosen medicines that relieve distressing withdrawal symptoms, reduce health risks and support stabilisation.
- Health stabilisation and building readiness for therapeutic work: Nutrition, hydration and rest are prioritised, giving patients a healthier baseline and readiness to begin psychological and therapeutic treatment.
- Supported move into structured residential rehab for continued treatment: After a 21-day detox, patients are guided into therapy within a live-in setting, helping them build stability and continue recovery in a supportive environment.
28-Day Drug and Alcohol Detox Process
A 28-day detox, often called a 4-week detox, allows time for steady withdrawal, physical recovery and therapeutic preparation. This timeframe is commonly chosen for people with more complex or longer-term substance addictions.
- Detailed medical screening and month-long detox planning: Clinicians carry out a comprehensive assessment of health and substance history, shaping a personalised four-week detox plan.
- Round-the-clock monitoring with specialist clinical oversight: Patients are supported continuously by medical and nursing teams, with adjustments made as needed to maintain comfort and safety.
- Carefully managed medication to support steady withdrawal relief: Medication may be used to reduce risks and ease distress, allowing patients to complete detox more safely and with less discomfort.
- Improving physical stability and preparing for psychological therapies: The focus moves beyond withdrawal, with health stabilisation helping patients gain energy and clarity to engage in addiction therapy.
- Smooth transition into long-term residential rehab programmes: After detox, patients enter residential rehabilitation where therapy, relapse prevention and whole-person care strengthen recovery.
30-Day Drug and Alcohol Detox Process
A 30-day detox, sometimes called a month-long addiction detox, is often recommended for people with more severe or complex substance dependence. This prolonged withdrawal management approach allows for thorough medical care, gradual stabilisation and a smoother transition into ongoing recovery.
- In-depth clinical evaluation with tailored month-long detox roadmap: Doctors and therapists conduct detailed assessments, shaping a personalised 30-day detox treatment plan based on medical, psychological and lifestyle factors.
- Continuous medical supervision and daily progress reviews: Patients receive 24-hour medical oversight with regular evaluations, ensuring any withdrawal challenges are addressed quickly while tracking recovery progress.

Medications Used for Long-Term or Extended Substance Detox
Medication may or may not be part of a long-term detox plan. Prescribing decisions are always case-by-case, depending on individual needs and the severity of addiction. Some medicines can be dangerous if misused, so they are only given under close medical supervision. Below are examples of commonly used options.
- Benzodiazepines (e.g., Diazepam, Chlordiazepoxide): Benzodiazepines are sometimes used during alcohol or sedative detox for gradual tapering, helping to reduce seizures, agitation and anxiety under strict medical control.
- Methadone: This medication can be prescribed in structured opioid replacement therapy, allowing people to stabilise gradually during longer opioid detox programmes while reducing cravings and withdrawal risks.
- Buprenorphine (Subutex, Suboxone): A partial opioid agonist that can be used in stabilisation and tapering, it reduces withdrawal distress while carrying a lower risk of misuse compared with full agonists.
- Naltrexone: Sometimes prescribed after opioid or alcohol detox, this medicine helps block the rewarding effects of substances and supports relapse prevention as part of an extended care plan.
- Acamprosate (Campral): This medication can be used in alcohol detox and long-term support to reduce cravings and help maintain abstinence, stabilising brain chemistry after heavy drinking.
- Antidepressants (e.g., SSRIs like Sertraline, Citalopram): These may be introduced during extended detox if patients have co-occurring depression or anxiety, supporting mental health alongside physical stabilisation.

Does Health and Medical Insurance Cover One-Month Detoxification Treatment?
Yes – health or medical insurance may cover one-month detoxification treatment, though the level of support varies depending on the provider and policy. Approval often depends on coverage limits, medical necessity, and whether the chosen detox setting meets insurance criteria.
If you are covered and authorised, Castle Craig accepts private health and medical insurance from several providers for our residential treatment. Once approved, our admissions team can then explain the process, liaise with insurers and help you understand what has been included.
How Much Does a 3-Week or 4-Week Residential Detox Cost?
In the UK, detox on its own typically costs £1,000–£6,000 for 7–10 days. A 21-day detox or a month-long detox alone could therefore cost between £3,000 and £18,000. These figures reflect medical supervision and stabilisation but do not include therapy or long-term rehabilitation.
When detox is part of a full residential plan, the cost usually falls between £18,000 and £40,000 per month. This covers not only detox but also evidence-based therapies, holistic care and structured aftercare. Detox is generally most effective when combined with full rehabilitation, as this addresses both the physical and psychological aspects of addiction – contact us today to find out more.
