Polysubstance use treatment in London should begin with a combined assessment of all the substances and medicines involved, the timing of use, physical and mental health, and the practical circumstances around it. A GP or local drug and alcohol service can help establish that picture. The aim is a connected plan, not a separate set of instructions for each substance.
“Polysubstance” describes involvement with more than one substance; it does not tell a clinician which treatment you need. Your history might involve alcohol and cocaine, opioids and sedatives, cannabis alongside prescribed medication, or another combination. The NHS treatment overview emphasizes assessment and an individualized plan based on your circumstances.
Describe the sequence, not just the list
A list of names is useful, but the order and purpose of use can be just as important to explain. You may use one substance socially, another to stay awake, and another because the following day feels difficult. You may use different substances on different days rather than together. Describe what actually happens without assuming that separate timing makes a detail irrelevant.
Prepare a simple recent timeline. Include days when you did not use, medicines taken as prescribed, and occasions when the pattern was unusual. If something came from an informal source, distinguish what you were told from what you can verify. Do not invent quantities to fill gaps in memory.
Explain what you were trying to achieve with each part of the pattern. Relief from anxiety, pain, sleeplessness, social pressure, or uncomfortable after-effects can point to questions that need clinical investigation. Your account is a starting point for assessment, not proof of a particular diagnosis.
Tell the team what is most urgent for you
You may be seeking help because of a medical scare, difficulty functioning, financial pressure, concern from family, or repeated unsuccessful attempts to change. State the immediate concern first. It helps the assessor distinguish a routine planning discussion from a need for a more urgent response.
Describe recent symptoms and any emergency care, including what substances or medicines were involved as far as you know. If you have discharge papers or a medicine list, bring them. Where there is a gap in information, ask how it can be resolved and who will obtain the relevant records.
If an overdose has occurred, life is at risk, or you cannot keep yourself or another person safe, call 999 or go to A&E. For urgent mental health advice, call 111 and select the mental health option. The NHS urgent-help page explains those routes. Do not use a routine treatment inquiry form for an emergency.
Find a London service that will assess the whole picture
At first contact, explain that more than one substance is involved and ask whether the service can assess the combined situation. Give your home borough, age, and any existing treatment contacts. If the first service has a limited remit, ask which team is appropriate and what information should accompany the referral.
The official Islington Better Lives information describes a local drug and alcohol pathway with assessment and care planning. It is one example of how support can be organized, not a guarantee of eligibility or a particular intervention for every London resident. Confirm the relevant catchment and current arrangements directly.
If you are considering private care, ask for a clinician to confirm suitability before paying for a fixed program. A website listing many addictions does not establish that the service can manage every combination or every level of medical need. You can use our first-assessment guide to prepare the information a service should consider.
Identify one person or team to coordinate the plan
Several professionals may have legitimate roles: an addiction clinician, GP, psychiatrist, pain specialist, therapist, or pharmacist. Ask who keeps an overview and how each professional’s recommendations will reach the others. Coordination should be an explicit arrangement, not an assumption that everyone can see the same records.
Consent also deserves a clear discussion. Ask which information will be shared, with whom, and for what purpose. If you have concerns about sharing a particular detail, raise them rather than withholding information without explanation. The team can explain how those concerns interact with clinical responsibilities.
Keep a concise contact record that distinguishes prescribing, routine support, administration, and urgent care. If an instruction is unclear or conflicts with another recommendation, contact the responsible clinicians to resolve it. You should not have to choose between competing medication plans on your own.
Separate clinical priorities from personal preferences
You may have a strong view about which substance you want to address first. Explain that preference and the reasons behind it. Then ask the clinician how they assess the sequence of care, what other needs must be considered, and how the plan can accommodate your goals where appropriate.
A combined plan should explain the rationale for its order without turning it into a universal rule for everyone using the same substances. Your current health, prescribed treatment, previous experiences, and daily circumstances all provide information for the professional assessment. Avoid copying another patient’s medication or withdrawal sequence.
When withdrawal management is part of the proposal, ask about the setting, professional responsibility, and ongoing treatment afterward. Our guide to withdrawal care involving multiple substances focuses on those specific service questions.
Keep mental health care connected
Describe mood, anxiety, sleep, trauma-related concerns, unusual experiences, and any established diagnoses. Explain the timing of changes without assuming that every symptom is caused by substances or, conversely, that substance use is unrelated. Ask which concerns need further assessment and who will undertake it.
NICE guidance on coexisting severe mental illness and substance misuse addresses coordinated care across services. Its scope is specific; it should not be used to label every person with multiple-substance use as having severe mental illness. The practical question is which professionals need to work together in your case.
If you already have a mental health team, ask whether a joint discussion would help. Clarify who reviews medication, who provides psychological treatment, and which team responds to a change in your condition. Our integrated dual diagnosis guide explains how to assess those arrangements.
Compare service capabilities in concrete terms
Ask what the program can provide directly and what it must obtain from another service. A referral relationship may be useful, but it is different from having the required professional or facility on site. Request an explanation of how external appointments are arranged and whether additional costs apply.
| Capability | Question to ask |
|---|---|
| Combined assessment | How do you assess all substances, medicines, and current health needs together? |
| Medical responsibility | Who makes and reviews medical decisions during treatment? |
| Psychological care | How is therapy selected from the assessment rather than assigned as a standard package? |
| External support | Which needs require another service, and how is that handover managed? |
| Change of setting | What happens if a different level of care becomes appropriate? |
For a residential proposal, verify the exact location and whether it is within London, elsewhere in Greater London, or outside the region. Ask how family contact, existing appointments, and return-home care will be managed. Geographic clarity is part of understanding the service, not an incidental booking detail.
Build the practical supports around the clinical plan
Discuss housing, work, childcare, money, transport, and the people who are part of your daily environment. These subjects may influence whether a proposed schedule can be followed. Ask which problems the treatment team can address itself and where it can help you find another appropriate service.
If different substances appear in different settings, explain those contexts separately. A plan for a work-related routine may need different practical discussion from a plan involving a social group or a shared household. Bring specific examples so that treatment conversations can examine real situations rather than an abstract instruction to avoid triggers.
Where a relative or trusted person wants to help, agree a realistic role. They might support transport, keep appointment information, or join a discussion with your consent. They should not be expected to interpret medical instructions or act as a substitute for professional monitoring.
Review the whole pattern over time
If you attend an emergency department or another clinic during treatment, tell the coordinating team and ask how the new information will be incorporated. Bring discharge instructions and any medication changes to review. Do not assume that every service automatically receives another organization’s records or knows that a new appointment has occurred.
Agree how progress will be discussed across the full substance and medication picture. If attention remains fixed on one substance, changes elsewhere may be overlooked. Be open about new products or changes in purpose, even if the original concern appears to be improving.
Review daily functioning as well as use: attendance, sleep, relationships, work, and contact with other clinicians. Ask how the team will respond if a plan is difficult to follow or if you return after a period without contact. Clear re-entry arrangements can be discussed before they are needed.
Before a program ends, confirm who will continue care and when. Our London aftercare guide explains the handover questions. A useful polysubstance care plan is one in which assessment findings, responsibilities, and practical support remain connected as your situation changes.
