ADHD and Substance Use: Finding Coordinated Care in London

ADHD and substance use care in London should connect an appropriately qualified ADHD clinician with the professionals addressing alcohol, drugs, or medication-related concerns. The first task is to establish what assessment and treatment are needed. The second is to agree who will prescribe, monitor, communicate, and continue care. An ADHD diagnosis alone does not settle those practical responsibilities.

The NHS adult ADHD guidance describes specialist assessment and treatment, including consideration of other conditions. When substance use is also present, give both teams the same accurate history. An incomplete account may lead to an unsuitable plan even when each professional is acting carefully on the information they have.

Clarify whether the question is diagnosis, treatment, or both

Adults arrive at this point in different circumstances. Some have a childhood diagnosis and need to reconnect with care. Others have never been assessed and recognize long-standing difficulties. Some are taking ADHD medication but are concerned about how they use it. These situations should not be grouped into a single generic “ADHD rehab” package.

Describe the problem you want the assessment to resolve. That might be whether a pattern of difficulties fits ADHD, whether another condition needs assessment, or how to continue an established treatment safely. If you already have a diagnosis, bring the report and previous treatment records. Repeating a full assessment may or may not be necessary; the receiving clinician should explain why.

A recent period of poor concentration is not enough to identify ADHD. Sleep disruption, substance use, emotional distress, and other health concerns may also need consideration. The assessment should examine the history and functional impact across life, rather than treating an online questionnaire score or a response to a stimulant as a diagnostic test.

Prepare a history that helps the specialist distinguish the issues

Write a brief timeline of attention, organization, restlessness, and impulsivity difficulties. Include school, work, home responsibilities, and relationships where relevant. Explain which difficulties existed before substance use began and which became noticeable later. It is acceptable to say that you cannot remember; uncertainty is more useful than an overly precise account created to fill gaps.

With your permission, a family member or someone who knew you earlier in life may contribute information. Old school reports can also add context if available. Their absence should be discussed with the assessor rather than becoming a reason to invent evidence. Ask what alternative information the service can consider when childhood records or relatives are unavailable.

Describe substance use in ordinary terms: what you use, when, what you expect it to do, and what difficulties follow. Include alcohol, recreational drugs, prescribed medication, nonprescription products, and medicines obtained elsewhere. The point is to support a complete assessment. You should not have to decide for yourself whether a pattern is “self-medication” or a separate disorder before asking for help.

Medication decisions need individual assessment

NICE ADHD guidance includes assessment of substance misuse and the possibility of medication diversion when considering treatment. Diversion means medicine being passed to someone for whom it was not prescribed. These questions should form part of a respectful clinical assessment, not an assumption that every person with a substance use history will misuse treatment.

A website cannot determine which medicine, if any, is suitable for a particular person. Ask the prescriber to explain the options, the reason for the recommendation, and what monitoring would be needed. If one option is unsuitable, ask what other support can proceed. Do not borrow medication, change a dose, or stop prescribed treatment to test an explanation yourself.

Be specific about practical problems. Missing a repeat prescription, taking medication differently from the plan, and struggling with a side effect are different issues. Each needs an appropriate response. A clinician can only help resolve them if they know what is happening, so ask how to report a concern between scheduled appointments.

Agree what shared care will mean in practice

Shared care is an agreed division of clinical work between services, often involving a specialist and a GP. It should not be assumed simply because a private clinic produces a diagnosis or sends a letter. The London ADHD coordination guide explains the questions to settle before relying on a transfer of prescribing.

Ask the specialist what care they provide after initial treatment is established, and ask the GP whether they can accept the proposed arrangement. Confirm who handles reviews, physical monitoring, prescription requests, and new concerns about substance use. If agreement is not possible, you need a realistic continuing-care plan before committing to a package whose future costs depend on that transfer.

For a patient already receiving addiction medication, both prescribing teams should know about the complete treatment plan. An appointment at one clinic does not automatically update every other clinical record. Ask how relevant information will be exchanged, what consent is needed, and which professional will contact the others if the plan changes.

A concrete East London example

The Tower Hamlets ADHD Service describes assessment and treatment optimization for adults aged 18 to 65 living in Tower Hamlets. Referrals are initiated through a GP. Its published information also asks patients to discuss shared care with their GP. This illustrates why checking the local pathway matters before assuming that a diagnosis guarantees ongoing prescribing elsewhere.

The service is based at Mile End Hospital, but its location does not make it a general access service for every London resident. East London NHS Foundation Trust also lists ADHD pathways for City and Hackney and Newham, alongside services outside London. Check the relevant borough service rather than selecting whichever address is easiest to reach.

ELFT’s assessment information explains that assessment can result in an ADHD diagnosis, further investigation, identification of another condition, or signposting to different support. The aim is an accurate explanation and useful plan. An assessment that identifies another need is not a failed appointment simply because it does not confirm the diagnosis initially suspected.

Addiction support can address current needs while assessment proceeds

Waiting for an ADHD appointment should not prevent discussion of current substance-related difficulties. The NHS guide to getting help for drug addiction describes routes through a GP or local treatment service. Tell the service about a suspected or established ADHD diagnosis and any relevant medication, even if specialist assessment is still pending.

Ask what the addiction intervention is intended to change. A useful plan might examine a particular pattern of use, prepare for a difficult social setting, or address a repeated breakdown in attendance. The provider should explain how the intervention relates to your goals. It should not promise that identifying ADHD will automatically remove cravings, dependence, or practical consequences.

The main adult ADHD guide and prescription medication guide cover different aspects of this decision. Prescribed treatment taken as agreed, physiological dependence on a medicine, and a pattern of uncontrolled use are not interchangeable descriptions. Ask clinicians to use precise language about the concern they are treating.

Make treatment easier to use

Practical adjustments can make a complicated care plan more manageable. Ask for appointment dates and actions in writing, one clear contact route, and a short summary of decisions. Discuss reminders, session length, and the option to check understanding before leaving. These requests can be useful regardless of whether the diagnostic process has been completed.

A London patient may be traveling between a GP, a specialist clinic, and a borough addiction service. Map the actual journey and time required before agreeing to a demanding schedule. If missed appointments have been a problem, explain the reason rather than accepting a vague description of poor motivation. Transport, work, childcare, and difficulty organizing tasks call for different practical solutions.

For example, a person might reliably attend an evening session near work but repeatedly miss an early appointment across the city. Discuss whether the plan can be adjusted without losing the necessary clinical input. Convenience alone should not determine treatment, but an impractical schedule can prevent an otherwise appropriate plan from being used.

Set goals that extend beyond a prescription

Agree what improvement would look like in daily life. This could include managing an agreed routine, completing essential tasks, reducing substance-related harm, or communicating more clearly with family. Different goals may belong to different professionals. Recording that division helps prevent every difficulty being attributed to ADHD or every difficulty being attributed to addiction.

Review the plan when circumstances change. Moving borough, leaving residential care, starting a new job, or changing prescriber can disrupt arrangements that previously worked. Ask for the next appointment and the responsible service before the current episode of care ends. A discharge letter is valuable, but it does not replace a confirmed receiving clinician when ongoing treatment is needed.

When to seek more immediate help

Urgent mental health concerns or serious physical symptoms should not wait for an ADHD assessment. In England, NHS urgent mental health guidance directs people to NHS 111’s mental health option for urgent support and to 999 or A&E when there is immediate danger. Tell the assessing professional about medication and substance use.

A well-connected plan leaves you with more than an appointment booking. You should know what question is being assessed, who handles each treatment decision, what support is available now, and how care will continue. Those details make ADHD and substance use treatment usable in everyday London life.
