A family can arrange an addiction consultation and a psychiatric appointment and still lack one coordinated treatment plan. England’s service data show why that matters: almost three quarters of adults starting substance-use treatment reported a mental-health need. The question is not simply how many professionals are available. It is who takes responsibility for the whole picture.
Key findings
74%: adults starting substance-use treatment in England in 2024/25 who reported a mental-health treatment need, up from 72% the previous year.
124,763: new starters with that reported need.
22%: those with a reported mental-health need who were not receiving treatment for it. These are service-entry figures, not population prevalence. [1]
18.5 million: US adults estimated to have both past-year mental illness and a substance-use disorder in 2025. This is a different population and definition from the English figures. [3]
The overlap is not a specialist afterthought
Reported mental-health needs affected a majority in every substance-use group shown. A reported need is not identical to a confirmed diagnosis, and receiving treatment does not establish its adequacy. Source: Office for Health Improvement and Disparities. [1]
The increase from 72% to 74% is two percentage points. More importantly, the scale shows why mental-health support cannot be designed only for an exceptional minority of addiction-service patients.
The figures do not explain every treatment gap. Someone may be waiting, may have declined a particular option, or may need further assessment. They do, however, support a clear service question: what happens when a person’s needs cross the boundary between addiction care and psychiatry?
A policy announcement is not yet an outcome
England’s December 2025 delivery framework for co-occurring mental-health and substance-use conditions calls for better joint working. It challenges exclusion from one service because the other problem is present. Its focus is coordinated, person-centered care. [2]
That is an important development, but a framework and its implementation are different things. The next test is whether referral arrangements, shared assessments, and continuity actually improve.
For journalists, the stronger story follows the patient pathway. Who coordinates care? Can someone access appropriate treatment for both needs? What changes when one service cannot provide part of the plan? Those questions are more informative than counting an announcement as a completed reform.
The US data show a different part of the picture
SAMHSA estimated that 7.0% of US adults had both past-year mental illness and a substance-use disorder in 2025. The young-adult estimate was 11.1%. Both classifications refer to the past year; the survey cannot establish that their criteria were present at exactly the same time. [3]
| Year | Adults 18 and older | Adults 18 to 25 |
|---|---|---|
| 2021 | 7.4% | 13.3% |
| 2022 | 8.0% | 14.7% |
| 2023 | 7.6% | 13.7% |
| 2024 | 7.7% | 13.0% |
| 2025 | 7.0% | 11.1% |
All years use the 2025 release’s revised mental-illness model. SAMHSA classifies the overall 2021 to 2025 adult trend as no change and the young-adult trend as decreased. That classification is not the same test as a comparison between two individual years. [3]
The young-adult decline belongs in the story alongside the continuing scale of need. Source: SAMHSA, figure 66 and table A.46B. [3]
Why 74% and 7% are not a country ranking
The English figure concerns people entering substance-use services who report a mental-health need. The US figure concerns all adults meeting two past-year classifications. Their populations and definitions differ.
Using those percentages to say one country has ten times the problem would be misleading. The same rule applies to GCC and Western European comparisons. More detailed reporting should not make a country look worse simply because it measures needs that another system does not publish.
Coordination does not mean identical treatment
A shared plan still needs decisions about safety, priorities, and timing. Some people require medical stabilization before other work. Others can receive several interventions together. Coordination means those decisions fit one clinical plan, not that every treatment starts on the same day.
The US National Center for PTSD provides one specific example. Its evidence summary supports appropriate trauma-focused care for people with PTSD and substance-use disorder. One diagnosis should not automatically exclude treatment for the other. Project Harmony includes 36 randomized trials, but its findings concern defined approaches and populations. They do not validate every program labeled integrated. [4]
A family should therefore ask how recommendations are reconciled and what happens when progress in one area is not matched in another. A long appointment list is not an answer to those questions.
Recovery needs more than one measure
| Area | Useful measures | Misleading shortcut |
|---|---|---|
| Mental health | Symptoms, functioning, adverse effects | Assume reduced substance use resolves every symptom |
| Substance use | Use, harms, disorder symptoms, agreed goals | Assume improved mood resolves substance-use problems |
| Daily life | Relationships, quality of life, personal priorities | Equate returning to work with complete recovery |
| Continuity | Follow-up participation and accepted handovers | Count a referral letter as a completed transfer |
This is a proposed framework, not a measured THE BALANCE outcome. Reports also need the number eligible for follow-up, how many participated, and the treatment received afterward. An outcome among respondents is not automatically an outcome among everyone admitted.
Why this matters for affluent and international families
Financial resources can make several consultations possible without establishing who coordinates them. In an international care arrangement, the practical questions include who keeps the treatment history, who communicates medication changes, and whether a receiving clinician has accepted the handover.
Relatives may notice inconsistencies, but they should not automatically carry clinical responsibility for resolving them. Family involvement should reflect the patient’s consent and preferences. A family office can organize logistics without directing clinical decisions.
The aim is a plan that remains understandable across clinicians and countries. Who should the patient contact if symptoms worsen? What support continues after discharge? Which professional reviews the combined picture? These questions test the proposed arrangement without assuming that every international pathway is fragmented.
What the numbers cannot tell us
The English gap does not prove a private program would produce better results. The US survey does not identify wealthy patients, executives, or family-business owners. Neither dataset evaluates THE BALANCE. The clinical evidence supports specific approaches rather than an unrestricted claim about integrated care.
The bottom line
Two appointments are not necessarily one treatment plan. The overlap between mental-health and substance-use needs is substantial in the populations studied. Families should ask whether care is coordinated and whether progress is measured across both areas, not simply whether each specialist is available.
For journalists
Key finding: 74% of new substance-use treatment starters in England reported a mental-health need; 22% of that group were not receiving treatment for it.
Important caveat: the English service figures and US population estimates are not directly comparable.
