What Are the Main Types of Addiction in the UK?

The UK faces two primary addiction categories: drug addiction and alcohol addiction, with cannabis, alcohol, and cocaine being the most prevalent substances. Cannabis remains the most commonly used drug, with 6.8% of adults aged 16 to 59 reporting use in the year ending March 2024.

Approximately 3.0% of people, around 1 million individuals, reported using a Class A drug in the last 12 months. Alcohol dependency affects an estimated 608,416 adults in England, making it one of the country’s most widespread addiction challenges alongside illicit drugs.

How Many People Face Drug Addiction Each Year in The UK?

2.9 million people aged 16 to 59 in England and Wales reported using any drug in the year ending March 2024, representing 8.8% of this age group.

Drug use is significantly concentrated among younger people, with 16.5% of those aged 16 to 24 years, approximately 971,000 young adults, using drugs in the past year. Cannabis dominates as the most widely used substance, followed by cocaine and other recreational drugs.

The frequency of drug use varies considerably across the population. Around 1.8% of people, approximately 610,000 individuals, were frequent drug users consuming substances more than once a month. However, the majority of drug users engage infrequently, with around three-quarters using drugs sporadically rather than regularly.

What Types of Drugs Are Most Commonly Used In The UK?

How Many People Face Alcohol Addiction Each Year?

608,416 adults in England were estimated to be alcohol dependent in 2019 to 2020, representing approximately 14 alcohol dependent adults for every 1,000 adults. The scale of alcohol-related harm continues to grow, with 2023 recording 10,473 alcohol-specific deaths across the UK, the highest number since records began.

This represents both the breadth of alcohol dependency and the increasing severity of alcohol-related health consequences.

Among adults in treatment between April 2023 and March 2024, 30% were there for alcohol problems alone. The impact extends beyond dependency, with alcohol-related hospital admissions showing 65% of patients being male, highlighting significant gender disparities in alcohol harm.

How Many People Are in Rehab in The UK at Any Point?

310,863 adults aged 18 and over were in contact with drug and alcohol treatment services between April 2023 and March 2024, marking a 7% rise from the previous year and the highest number since 2009 to 2010. This figure includes all forms of treatment from outpatient services to residential rehabilitation. Within this total, 12,100 people received treatment in inpatient settings, while 5,438 people were in residential rehabilitation during the same period.

The demand for treatment services has grown substantially, with 158,991 adults entering treatment in 2023 to 2024, higher than the previous two years. Just under half of all adults in treatment, 44%, were receiving help for opiate problems, making this the largest substance group. Alcohol problems alone accounted for the second-largest group at 30% of all adults in treatment.

What Is the Recovery and Relapse Rate in the UK?

47% of people who left treatment in 2023 to 2024 successfully completed their treatment free from dependence, representing nearly half of all treatment exits. While this demonstrates that recovery is achievable, it also indicates that just over half of those who exit treatment do so without completing their programme successfully. The completion rate has remained relatively stable, at 46% in the previous year and 47% in 2023 to 2024.

Relapse remains a significant challenge in addiction recovery. Studies indicate that approximately two-thirds of people entering treatment for alcohol addiction maintain sobriety in their first year, meaning about one-third experience relapse. Research shows relapse rates can be as high as 65% to 70% in the 90-day period following treatment completion, highlighting the critical importance of the early recovery period.

The data reveals that longer treatment duration significantly improves outcomes. People receiving 90 days or more of treatment demonstrate substantially better long-term recovery rates compared to those in shorter programmes. The risk of drug relapse persists even after extended periods, with approximately 40% risk remaining after two years of recovery and 15% risk after five years, confirming that addiction requires ongoing management beyond initial treatment.

Which UK Regions Have the Highest Addiction Rates?

The North East of England has the highest addiction rates in the UK, with 25.7 alcohol-specific deaths per 100,000 people and 167.6 drug poisoning deaths per million people in 2024. Regional disparities are stark, with northern England experiencing significantly higher rates than other parts of the country. The East of England had the lowest alcohol-specific death rate at 11.5 per 100,000, more than twice as low as the North East.

For drug-related issues, the North East continues to face the most severe challenges, with drug misuse death rates of 107.1 per million people. Scotland recorded 22.6 alcohol-specific deaths per 100,000, while Wales reported 17.7 and Northern Ireland 18.5 per 100,000, all substantially lower than the North East of England.

What Is The Regional Breakdown of Substance Misuse In The UK?

The differences between regions reflect complex socioeconomic factors including levels of deprivation, funding for treatment services, and local drug markets. People in the most deprived areas consistently face significantly higher rates of addiction-related hospital admissions and deaths. The North West and North East’s higher rates are attributed to factors including underfunding of services, higher social deprivation, and greater accessibility to substances through numerous outlets.

Conclusion

Addiction affects millions of people across the UK each year, with 2.9 million using drugs and over 600,000 dependent on alcohol. While treatment services are helping more people than ever before, with 310,863 adults in contact with services in 2023 to 2024, significant challenges remain.

Recovery rates show that 47% of people successfully complete treatment, but relapse rates remain high, particularly in the first 90 days after treatment. Regional disparities persist, with the North East facing the most severe addiction crisis, recording rates more than double those of the East of England. Understanding these statistics is crucial for developing targeted interventions and ensuring adequate support reaches those who need it most.
