Published local treatment outcomes, estimated opiate/crack prevalence and protected drug and alcohol funding, each with its own reference period.

FieldEvidence
Reference period2022/23 · 2024/25 · 2026/27
CoverageCity of London
StatusMissing or combined-area measures

Area codeE09000001
CountryEngland
Opiate/crack prevalence (2022/23)231 estimated people aged 15–64; 95% limits 181–289
Prevalence rate (2022/23)24.4 per 1,000 aged 15–64; 95% limits 19.1–30.5
Prevalence population denominator (2022/23)9,471
Prevalence geographyCity of London
Prevalence method and limitsCapture-recapture modelling of community treatment, criminal justice and mortality records. London and the rest of England are modelled separately. Opiates and/or crack only; excludes powder cocaine, cannabis and other drugs. Model estimates, not counts of diagnosed dependence. Not comparable with 2016–2020 estimates because methodology changed. Does not measure unmet need.
Opiate treatment completion (2024/25)Not published separately / missing; not zero. Value for Hackney and City of London combined
Opiate completion definitionThe number of adults that successfully complete treatment for opiates in a year and who do not represent to treatment within 6 months. Denominator: The total number of adults in treatment for opiate use in a year .
Non-opiate treatment completion (2024/25)Not published separately / missing; not zero. Value for Hackney and City of London combined
Non-opiate completion definitionThe number of adults that successfully complete treatment for non opiates in a year and who do not re present to treatment within 6 months. Denominator: The total number of adults in treatment for non opiate use in a year .
Protected funding allocation (2026/27)£4,632,092
Funding scopeProtected drug and alcohol funding within the consolidated public health allocation. Allocation, not actual expenditure, capacity or total local treatment spending. Includes drug and alcohol prevention, treatment and recovery; do not divide by the opiate/crack prevalence estimate as if it were spending per patient.
Unmet need / waiting timesNo compatible current local estimate included. Do not derive unmet need by subtracting different age groups, drugs or periods.
Historical service use (2020/21)3.730934 per 1,000 adults aged 18+; 34 people. Historical, not current access.

Interpretation limits

Value for Hackney and City of London combined Different indicators refer to different periods and populations. Treatment completion is not an access measure or an overall service-quality score. Long-term treatment can be appropriate; case mix differs. Missing and combined values are not zero. No current waiting-time or local unmet-need estimate is provided.
