About the data


How the data is organised

There are two over-arching categories, with five sub-categories:

1. Prevalence and Risks

2. Treatment and Recovery

Detailed technical definitions are available from here (pdf).

What the latest available data tells us

Prevalence and Risks

Data estimating the number of opiate and/or crack users (OCU) in England is now available going back to 2004/05 (see https://www.gov.uk/government/collections/alcohol-and-drug-misuse-and-treatment-statistics#prevalence-data-and-analysis for historic data and detailed methodology). The OCU population in England in 2014/15 is estimated to be just over 300,000, a fall of around 10 per cent since 2004/05, but nevertheless a significant number of current OCUs. There has been a much larger decline in OCU injectors: a reduction of over a third since 2004/05, from nearly 140,000 to just under 90,000 in 2011/12. Please note that, unlike estimates of the total OCU population, estimates of the OCU injectors have not been updated to 2014/15.

The general downward trend in prevalence in England masks some regional variation, although there is a need to interpret this cautiously as the estimates tend to be subject to broad confidence limits. The estimated number of OCUs in London fell significantly, by more than a quarter between 2004/05 and 2014/15, while in three regions (the North East, East of England and East Midlands) the estimated numbers of OCUs for 2014/15 were higher than in 2004/05, although these changes were not statistically significant. There were significant decreases in injecting of these drugs in most regions.

The latest data shows that the areas with high prevalence of opiate and crack use tend to be urban, broadly correlating with measures of socio-economic deprivation, although there are exceptions. A number of areas, particularly urban centres, in the North East, North West and Yorkshire and the Humber are notable as they experience significantly high rates of both use and injection of these drugs compared to the national average.

The rate of alcohol-related hospital admissions varies significantly across the country, with almost all areas in the North East experiencing significantly high rates, while many areas in London and the South East experience rates that, while comparatively low are nevertheless significantly higher than 20 years ago. A detailed suite of indicators concerning alcohol harm is available from the Local Alcohol Profiles for England (https://www.gov.uk/government/collections/local-alcohol-profiles-for-england-lape).

There are estimated to be just under 600,000 adults in England who are alcohol dependent and potentially in need of specialist assessment and treatment. This is estimated to be around 1.4 per cent of the adult population (see https://www.gov.uk/government/collections/alcohol-and-drug-misuse-and-treatment-statistics#prevalence-data-and-analysis). Nationally, just over half (53 per cent) of those who are alcohol dependent are estimated to display mild dependence, 29 per cent moderate dependence and 18 per cent (over 100,000 people) severe dependence. There are very broad confidence intervals around the estimates of dependent drinking, but despite this, there are a number of areas which across the country which have significantly high rates compared to the national average.

Treatment and Recovery

Ensuring quick and easy access to treatment for those who need it is vitally important and can make all the difference to those affected. In 2016/17, 99 per cent of those seeking help for their drug use waited less than three weeks from the time they were referred to the time they started a structured treatment programme.  The figure was only slightly lower than that, for those referred for help with their alcohol use with 98 per cent waiting less than three weeks from the time of the referral to when their treatment began, indicating that there was general ready availability of drug and alcohol treatment in England.  Areas with longer waiting times seem to have no obvious pattern of connections between them.

Recovery from drug or alcohol dependence is achievable and local areas can do much above and beyond commissioning drug and alcohol treatment to ensure that all services they provide, commission or support, promote a positive message of recovery from dependence.  Where this is done well recovery is more likely to be achieved and sustained.  Access to mutual aid is known to be of particular benefit.

Successful completion of drug treatment is used as the key proxy measure of recovery, because an individual is only recorded as having completed treatment successfully if they are assessed by the clinician treating them as free from dependence. The measure includes a non-representation element meaning that individuals don’t get counted if they come back into treatment within six months. This is the key proxy measure of recovery included within the Public Health Outcomes Framework (indicator 2.15).

Nationally, 7 per cent of opiate users in treatment in 2016 completed treatment successfully in that year by this measure.  It is important to note that this does not mean that only 7 per cent of opiate users recover.  This is the in-year proportionate rate - and tells us something about the effectiveness of the treatment and the area in general in promoting recovery - rather than telling us about an individual’s likelihood of recovery. Recovery from dependent use, particularly of opiates is known to be a long-term process and for many it may take longer than one year.

Over the twelve years between April 2005 and March 2017, 25 per cent of opiate users successfully completed treatment and have not returned to it. For users of other drugs, the annual successful treatment completion rate in 2016 was 37 per cent, with the longer term recovery rate again higher at 53 per cent. The annual successful treatment completion rate for those in alcohol treatment is slightly larger again, at around 39 per cent, with a longer term recovery rate of 55 per cent. There is a clear message here: people can and do recover from drug and alcohol dependence.

When considering opiate successful completion rates across the country, most areas do not deviate significantly from the national average, while there is more variation in the rates for users of other drugs and for alcohol.  Some areas in London may see their local successful completion rate for users of other drugs affected by high numbers of crack cocaine users in treatment.  Users of crack cocaine (without opiates) generally experience lower successful completion rates than others in the 'other drugs' category.

Detailed statistics on alcohol and drug treatment, including a wide range of additional information collected by the National Drug Treatment Monitoring System (NDTMS), are published on NDTMS.net with official statistics released annually by PHE (see https://www.gov.uk/government/collections/alcohol-and-drug-misuse-and-treatment-statistics#alcohol-and-drug-treatment-statistics:-adults).

Actions to tackle alcohol and drug problems

Locally, alcohol and drug problems are best addressed by a range of evidence-based interventions comprising prevention activities, early interventions targeted at those who are particularly vulnerable to the harms associated with alcohol and drug use, and the delivery of recovery-focused treatment and support.  Local Authorities are responsible for the commissioning of drug and alcohol treatment for their population.

Effective interventions require partnership working between a range of organisations. Local authorities, including elected members, directors of public health, children and family services, NHS and adult social care; police and other criminal justice agencies; specialist treatment providers, Jobcentre Plus and the Work Programme, and many others, all have a vital role to play.

Public Health England (PHE) promotes a balanced and ambitious approach to reduce the harm to health and wellbeing caused by alcohol and drugs. PHE supports local areas by providing expertise, evidence, data and guidance on effective interventions. Evidence-based resources supporting the commissioning and delivery of recovery-focused treatment can be found on the Alcohol and drug misuse prevention and treatment guidance page.

Every £1 spent on young people’s drug and alcohol interventions is estimated to save between £5 and £8, while every £1 spent on adult drug treatment is estimated to save £4 and on adult alcohol treatment is estimated to save £3. The savings are largely made in health, crime and welfare costs.
