The research on ADHD and addiction is striking: people with ADHD are 23 times more likely to develop a substance use disorder than those without. Yet this connection is routinely missed both in clinical settings and in families who see someone struggling with addiction without knowing that untreated ADHD may be driving it.
At Anker Huis, we treat this combination frequently and well. Understanding the ADHD-addiction link is the first step towards getting the right help.
What Is ADHD?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition characterised by:
- Inattention: difficulty sustaining focus, distractibility, forgetting tasks, losing things
- Hyperactivity: restlessness, inability to stay still, excessive talking
- Impulsivity: acting without thinking, difficulty waiting, interrupting
ADHD exists in three presentations: predominantly inattentive, predominantly hyperactive-impulsive, and combined. The inattentive type is frequently undiagnosed particularly in adults and in those who compensated well in structured environments.
ADHD is a brain-based condition involving differences in dopamine regulation not a character flaw, not bad parenting, and not something that goes away with effort or discipline.
Why Does ADHD Increase Addiction Risk?
1. Dopamine Dysregulation
ADHD involves underactivity of the dopamine system. Dopamine is central to motivation, reward, and attention. People with ADHD have a chronically understimulated reward system which means:
- Natural rewards (completing tasks, social connection) feel less rewarding
- They are more drawn to highly stimulating activities and substances that rapidly elevate dopamine
Substances especially stimulants, cannabis, and alcohol provide a rapid dopamine response that temporarily alleviates the restlessness and attention difficulties of ADHD.
2. Impulsivity
Impulsivity is a hallmark of ADHD. Impulsive people are more likely to experiment with substances, more likely to increase use, and less likely to pause before using despite known consequences. Impulsivity reduces the distance between the thought “I want to use” and the action.
3. Self-Medication
Many people with undiagnosed ADHD discover that certain substances improve their symptoms:
- Cannabis can temporarily reduce restlessness and improve focus for some ADHD individuals
- Alcohol reduces the social anxiety and impulsivity that often accompanies ADHD
- Stimulant drugs (cocaine, methamphetamine) dramatically increase focus and energy
This self-medication is not strategic. People don’t typically think “I’m self-medicating my ADHD.” They just notice that the substance helps them feel more functional.
4. Boredom and Sensation-Seeking
The understimulated ADHD brain is intolerant of boredom. Substances provide intense stimulation. Many people with ADHD describe their substance use as driven by a need for something more engaging than their current reality.
5. Unstructured Environments
ADHD symptoms are most problematic in unstructured situations. When schooling ends, when a structured job ends, when a relationship that provides structure ends the ADHD person may be particularly vulnerable to substance use filling the void.
The Undiagnosed ADHD Problem
A significant proportion of adults who present with addiction have never been diagnosed with ADHD. Several factors contribute to this:
- ADHD is underdiagnosed, particularly in adults and in those who present primarily with inattention rather than hyperactivity
- The comorbid anxiety and depression that often accompany ADHD attract treatment while the underlying ADHD is missed
- Substance use masks ADHD symptoms (particularly stimulant use which compensates for attention deficits)
- The chaotic lifestyle of active addiction makes ADHD difficult to assess
At Anker Huis, we routinely assess for ADHD as part of our comprehensive dual diagnosis assessment. A significant proportion of clients receive a first-time ADHD diagnosis during treatment.
How We Treat ADHD and Addiction Together at Anker Huis
Step 1: Comprehensive Assessment
Our psychiatric team conducts a thorough assessment that explicitly evaluates for ADHD alongside addiction and other mental health conditions. This includes clinical interviews, structured assessment tools, and (where appropriate) history from family or partners who know the person well.
Step 2: Stabilisation
During the early phase of treatment, we focus on achieving physical and emotional stabilisation before ADHD assessment is finalised. Active substance use can mimic or mask ADHD symptoms.
Step 3: Parallel Treatment
Once ADHD is confirmed, treatment addresses both conditions:
- Medication: Non-stimulant ADHD medications (atomoxetine, guanfacine) are preferred in early recovery. Stimulant medications may be considered later where necessary and clinically indicated.
- Psychoeducation: Understanding how ADHD has driven life patterns and substance use changes the narrative from “I’m weak” to “my brain works differently.”
- CBT adapted for ADHD: Skills for time management, task completion, and impulse management
- Mindfulness: Particularly effective for ADHD-related impulsivity and attention
FAQ: ADHD and Addiction
Does everyone with ADHD develop an addiction? No. ADHD increases risk but does not cause addiction in everyone. Risk factors also include family history, early substance use, trauma, and co-occurring conditions.
Can ADHD medication cause addiction? Stimulant medications (methylphenidate, amphetamines) used to treat ADHD carry some addiction risk in those who misuse them. Non-stimulant alternatives are available and often preferred in people with addiction histories.
How do I know if ADHD is behind my addiction? An assessment with a specialist is the only reliable way to determine this. If you have a history of attention difficulties, impulsivity, chronic disorganisation, or if stimulants feel unusually normal rather than stimulating to you ADHD assessment is worthwhile.
Does Anker Huis treat ADHD and addiction? Yes. Dual diagnosis including ADHD is specifically within our scope.
