World Drug Day 2026: Understanding drug misuse and the role of drug testing in the UK

Observed annually on 26 June, International Day against Drug Abuse and Illicit Trafficking – also known as World Drug Day – is a day dedicated to raising awareness of the global impact of drug misuse and the illicit trade that drives it.

Established by the UN General Assembly in 1987, the day brings together governments, organisations, healthcare professionals, and communities to reflect on the scale of the drug problem worldwide and promote evidence-based responses to it.

This year’s theme, “World drug problem: persisting issues, new challenges, innovative responses”, reflects the reality that while drug misuse is not a new problem, its complexity continues to evolve. New substances, changing patterns of use, and the growing sophistication of illicit drug markets mean that the response must continually adapt.

In the UK, this evolution is clearly visible. Drug misuse remains widespread, with implications that extend far beyond the individual, affecting families, children, the legal system and the workplace.

Here, we explore the current picture of drug misuse in the UK and how drug testing can play a role in addressing its impact.

The scale of the problem

According to the United Nations Office on Drugs and Crime (UNODC) World Drug Report 2024, the number of people who use drugs globally rose to 292 million in 2022; a 20% increase over the previous decade.  

Despite years of international efforts, global drug use and the number of substances available on illicit markets continue to rise.

In the UK, the picture is similarly concerning. Data from the Office for National Statistics (ONS) covering the year ending March 2025 found that:

• 8.7% of adults aged 16-59 reported using an illegal drug in the previous 12 months
• Among adults aged 16-24, prevalence was significantly higher, at 15.1%
• Cannabis remains the most widely used drug, with 6.5% of adults aged 16-59 reporting use in the past year. Of those, over a third used it more than once a month
• Cocaine and ecstasy also remain prevalent, while ketamine use has increased among adults aged 16-59
• There were 5,565 drug poisoning deaths registered in England and Wales in 2024, of which 3,736 were identified as drug misuse deaths

The data also challenges long-standing assumptions about who is affected by drug misuse.

While younger adults continue to report the highest levels of use, drug use has increased among older age groups, including those aged 45-54, compared with 2015.

Adults with household incomes of over £52,000 per year were also more likely to have used a Class A drug than those in several lower income brackets, underscoring the fact that drug misuse cuts across age, income, and background.

How drug misuse affects families, children and communities

The impact of drug misuse is rarely contained to the person using. It extends outward, affecting families, children, relationships, and communities in ways that can be profound.

For families, living with a loved one who misuses drugs can create an environment of uncertainty, emotional strain and, in some cases, risk.

Children growing up in households where drug misuse is present may experience neglect, instability, or disruption to their education and development. In some cases, concerns about parental drug use can lead to involvement from social services, local authorities, or the family courts.

In legal settings, drug misuse is a recurring and significant issue. It frequently arises in:

• Child custody and contact proceedings, where a parent’s substance use may be relevant to assessments of parenting capacity and the safety of contact arrangements
• Safeguarding investigations, where social workers and local authorities need objective evidence to make informed decisions about a child’s welfare
• Family mediation, where allegations of drug misuse can undermine trust between parties and complicate discussions about parenting arrangements

Beyond the family, drug misuse also places significant pressure on public services, including healthcare, law enforcement, and the criminal justice system.

How drug testing can help

Drug testing cannot solve the complex social and personal challenges that underlie drug misuse, but it can play a role in providing clarity, supporting informed decision-making, and helping individuals and professionals take appropriate action.

• For private individuals and families

  For some people, concerns about drug misuse are deeply personal. You may be worried about a family member, a partner, or someone close to you, and looking for answers that can help you understand the situation more clearly.

  Our peace of mind drug testing is designed for exactly these circumstances. Whether you’re seeking reassurance or need clarity before deciding on next steps, a private drug test can provide fast, accurate results discreetly and confidentially.

  As the name suggests, the results of peace of mind drug tests are for your own personal use and cannot be used in legal proceedings.

• For legal proceedings and safeguarding

  Where drug testing is required as part of family court proceedings or safeguarding investigations, the requirements are more specific. Samples must be collected under strict chain of custody conditions by a professional sample collector, ensuring that results are legally admissible and suitable for use in court.

  AlphaBiolabs’ court-approved drug testing services are trusted by family law solicitors, social workers, and local authorities across the UK. All analysis is performed at our UKAS 17025-accredited UK laboratory, and our reports are accepted in every UK family court.

  We also offer court-approved drug testing for private individuals needing a drug test for other legal or official purposes.
