ADHD and addiction: the risks of overlooking neurodiversity

ADHD affects an estimated 2–5% of adults worldwide, yet in the UK it remains underdiagnosed and undertreated. This gap has consequences that extend far beyond individual well-being. It shapes how people interact with education, employment, mental health services, and crucially, addiction treatment.

Despite growing awareness, ADHD is still often misunderstood. Many adults reach their 30s, 40s, or later without a diagnosis, having spent years developing coping strategies that mask symptoms but create new difficulties. For some, this includes turning to substances to manage restlessness, emotional overwhelm, or chronic underperformance.

When ADHD goes unrecognised, these patterns can escalate into dependency – not because of moral failure, but because people are trying to soothe a brain that feels constantly “too much” or “not enough.”

Understanding this overlap is also essential if the UK’s drug strategy is to be effective, compassionate, and grounded in evidence.

The overlap between ADHD and addiction

Research consistently shows that people with ADHD are 2–3 times more likely to develop a substance use disorder (SUD) than those without ADHD. Long‑term studies also indicate that 1 in 4 adults with ADHD will experience SUD at some point in their lives.

This connection is not incidental. ADHD‑related traits, such as impulsivity, emotional dysregulation, difficulty with planning, and a tendency toward “all or nothing” behaviour, can make substances feel like a quick solution. Alcohol may temporarily soften restlessness; cannabis may quiet a racing mind; stimulants may help someone feel focused for the first time. Without understanding the underlying neurodevelopmental condition, these coping mechanisms can become entrenched.

Importantly, many people with ADHD do not recognise these patterns as symptoms. They simply feel “different,” “too intense,” or “never quite in control.” When substances offer temporary relief, the risk of dependency increases.

Where the UK drug strategy may fall short

The UK’s drug strategy emphasises enforcement, early intervention, and treatment pathways. These are important pillars, but ADHD is rarely mentioned explicitly, despite its strong association with addiction and mental health challenges.

This omission matters because:

• ADHD is highly prevalent among people accessing addiction services
• untreated ADHD is linked to poorer treatment outcomes, higher relapse rates, and reduced engagement
• ADHD‑informed care improves retention and reduces substance use

A drug strategy that does not explicitly address ADHD risks missing a major driver of addiction‑related harm. Without recognising neurodiversity, services may unintentionally set people up to struggle, not because they lack motivation, but because the support offered does not match their needs.

What this means for individuals

Many readers may recognise themselves in these patterns without having a formal ADHD diagnosis.

You might notice:

• feeling overwhelmed by everyday tasks
• difficulty regulating emotions
• a tendency toward “all or nothing” behaviour
• using substances to cope with stress, restlessness, or sleep
• struggling with impulsive decisions
• repeated attempts to quit substances without understanding the underlying drivers
• a lifelong sense of being “behind,” “too much,” or “not enough”

These experiences don’t automatically mean you have ADHD, but they can be signs that neurodiversity is part of the picture. For many people, understanding this link is the first step toward self‑compassion and meaningful change.

How CBT can help and what the evidence says

Cognitive Behavioural Therapy (CBT) plays a central role in supporting people with ADHD, addiction, or both, and importantly, this is grounded in evidence‑based practice. The NICE Guidelines (2018) recommend CBT adapted for ADHD as a core psychological intervention for adults who continue to experience significant impairment.

Adapted CBT typically includes:

• emotional regulation strategies
• support with organisation and planning
• techniques for managing impulsive patterns
• skills for breaking down overwhelming tasks
• approaches tailored to ADHD‑specific thinking styles

This structured, practical approach helps people understand their patterns and develop tools that work with their brain rather than against it.

CBT for addiction

CBT is also one of the most widely supported treatments for substance use disorders.

CBT for addiction can help people:

• identify triggers
• understand the function substances serve
• build alternative coping strategies
• reduce relapse risk
• strengthen motivation and self‑efficacy

Why combining these approaches matters

When someone experiences both ADHD and addiction, adapted CBT and addiction‑focused CBT can be integrated.

This dual approach acknowledges that:

• ADHD can make recovery harder
• executive‑function challenges affect consistency
• emotional dysregulation can increase relapse risk
• shame and self‑criticism often run deep

Therapy offers a space to explore these patterns without judgement and to build strategies that support long‑term well-being.

You don’t need a diagnosis to seek support

Many people come to therapy simply because life feels harder than it should, or because they recognise patterns they want to change.

CBT can help you:

• understand the link between neurodiversity and coping behaviours
• build emotional regulation and grounding skills
• develop routines that work with your brain
• explore triggers and patterns around substance use
• strengthen motivation and self‑compassion
• navigate ADHD assessment pathways if you choose to pursue one

Therapy is not about labelling – it’s about understanding yourself more deeply and finding ways to move forward.

Why this matters now

As the UK continues to refine its drug strategy, overlooking ADHD risks widening existing gaps in care. A neurodiversity‑informed approach would not only improve outcomes for individuals but also help to reduce pressure on addiction services and mental health teams.

Recognising ADHD is not a niche issue – it is a public health necessity. By understanding the overlap between ADHD and addiction, and by ensuring people can access the right support at the right time, we can create a more compassionate and effective approach to substance use in the UK.
