Addiction
Addiction is a complex condition characterised by a compulsive need to use a substance or engage in a behaviour, despite harmful consequences. For decades, society has viewed addiction as a lack of willpower. But at the Matthew Lock ADHD Charity, we know the truth: for individuals with ADHD, addiction is rarely about making 'bad choices'. It is almost always an attempt to self-medicate a struggling, unsupported brain.
​
Research has uncovered a profound correlation between ADHD and severe addiction. People with ADHD are significantly more vulnerable to developing substance use disorders (SUDs) and behavioural addictions, often experimenting earlier in life and struggling harder to quit. Understanding why this happens is the first step in breaking the cycle.
Shared underlying mechanisms
Why is an ADHD brain so drawn to addictive substances and behaviours? The answer lies in neurobiology and the daily exhaustion of living in a neurotypical world.
The dopamine deficit
The ADHD brain naturally lacks dopamine (the neurotransmitter responsible for pleasure, motivation, and reward). Addictive substances and behaviours provide a massive, instant surge of dopamine. For an ADHD brain, an addiction is often a biological attempt to feel 'normal'.
Self-medication
Individuals with undiagnosed or poorly managed ADHD live with a relentlessly busy brain that cannot 'switch off'. They frequently use substances to forcefully alter their state: using alcohol to quiet racing thoughts, or nicotine/stimulants to finally focus on their work.
-
Severe impulsivity
A core trait of ADHD is acting without thinking. This makes individuals far more prone to experimenting with drugs or engaging in risky behaviours without pausing to consider the long-term consequences.
-
Sensation-seeking
Many people with ADHD possess a heightened need for novelty, thrill and excitement to stimulate their underactive nervous systems, naturally drawing them toward risky, high-reward scenarios.
-
Emotional dysregulation
ADHD causes individuals to feel emotions at 100% intensity. When the pain of rejection sensitive dysphoria (RSD), anxiety or depression hits, they may turn to substances simply to numb the overwhelming emotional agony.
Common addictions in ADHD
People with ADHD are at risk for a wide range of addictions, including:
Substance use disorders
alcohol
Individuals with ADHD are statistically more likely to start drinking earlier, engage in binge drinking, and develop alcohol use disorder. Alcohol acts as a central nervous system depressant, temporarily silencing the chaotic, hyperactive ADHD mind.
nicotine
Nicotine use from smoking and vaping is vastly more prevalent in the ADHD community. Because nicotine is a stimulant, many undiagnosed individuals unknowingly use it to temporarily improve their focus and working memory.
cannabis
Many turn to cannabis to self-medicate intense anxiety, sensory overload, or physical hyperactivity. However, chronic use heavily impairs executive function, ultimately worsening ADHD issues like short-term memory and motivation.
Illicit and Prescription Drugs
The risk for misusing opioids, benzodiazepines and illicit stimulants (like cocaine) is significantly higher as individuals desperately search for a way to regulate their mood and energy.
Behavioural addictions
Addiction isn't just about chemicals; behaviours can also hijack the brain's dopamine reward system.
gambling
The perfect storm of ADHD impulsivity, thrill-seeking and the instant, unpredictable dopamine hits of winning makes gambling highly addictive for this community.
gaming
The immersive, structured and instantly rewarding nature of video games provides exactly what the ADHD brain craves. Without intervention, it can lead to excessive, life-disrupting use.
internet and
social media
The endless scrolling of social media provides a constant, low-effort drip of novelty and stimulation, perfectly capturing the attention of a dopamine-starved brain.
compulsive shopping
The impulsivity of ADHD frequently manifests in financial recklessness. The 'thrill of the purchase' provides a fast dopamine hit, often leading to severe debt and hidden spending.
food addiction
Highly processed, sugary foods provide rapid neurochemical rewards. Binge eating is a highly common, yet rarely discussed, method of self-medication for ADHD emotional distress.
Coping strategies and integrated treatment
Traditional addiction treatment programs often fail neurodivergent individuals because they only treat the addiction. If you take away the substance but leave the ADHD untreated, the brain is still starving for dopamine, making relapse almost inevitable. Effective treatment must address both conditions simultaneously:
Dual diagnosis treatment
Seek out programs specifically designed to treat mental health disorders and substance use concurrently. Treating the underlying ADHD is frequently the key to unlocking addiction recovery.
Strategic medication management
There is a common myth that giving ADHD stimulant medication to someone with a history of addiction is dangerous. In reality, medical studies show that properly treating ADHD with correct medication reduces the urge to self-medicate and lowers the risk of relapse. (This must always be carefully monitored by a doctor.)
Tailored psychotherapy
-
Cognitive behavioural therapy (CBT): Helps individuals identify the negative thought patterns that trigger the need to use.
-
Dialectical behaviour therapy (DBT): Highly effective for ADHD, DBT teaches distress tolerance (how to survive intense emotional pain without reaching for a substance).
Holistic dopamine replacement
Recovery requires finding safe ways to give the brain the dopamine it needs. High-intensity exercise, martial arts, creative arts, and mindfulness can provide natural, healthy stimulation.

What it looks like in everyday life
When a child has both ODD and ADHD, the behaviours from each disorder overlap and heavily exacerbate each other. This creates a deeply exhausting cycle for both the child and the family:
The 'brick wall' response:
Heightened levels of defiance, especially in highly structured settings like school, where the child’s ADHD makes it physically painful to sit still and follow rigid rules.
Refusal to transition
Extreme meltdowns when asked to switch from a high-dopamine activity (like video games) to a low-dopamine activity (like homework), leading to explosive arguments.
-
Social isolation
The impulsivity of ADHD combined with the irritability of ODD can alienate peers, leaving the child isolated, which only deepens their anger and resentment.
Timely detection matters
Untreated ADHD creates a devastating pipeline to addiction. The tragedy is that many people lose their lives to substance abuse or suicide before anyone ever realises that underlying neurodivergence was the root cause of their pain.
At the Matthew Lock ADHD Charity, we advocate for early screening and compassionate intervention. By diagnosing ADHD early and providing the right support, we can prevent the desperate need to self-medicate and give individuals the future they deserve.
Lived experience: ADHD and addiction
"For years, they told me I was just an alcoholic. But drinking was never about partying for me; it was the only way I knew how to turn off the 15 different radio stations playing in my head all at once. When I finally got diagnosed with ADHD at 35 and started proper medication, the constant, desperate craving for a drink just... vanished. My brain finally had peace."
​
"The impulsivity is what ruins you. I didn't want to spend my rent money on gambling, but the urge hits you so fast, and the need for a dopamine rush is so intense that my brain bypassed all logic. It wasn't until I learned about my ADHD that I realised I wasn't an evil, selfish person; I had a neurological disorder that I needed professional help to manage."
​
"Before my diagnosis, I lived in a constant state of sensory overload and anxiety. I smoked cannabis every single day just to survive the sheer exhaustion of existing in a loud world. Treatment didn't just teach me how to stop using; it taught me how to accommodate my autism and ADHD so the world didn't hurt so much anymore."

NIDA extensively documents the high co-occurrence of ADHD and Substance Use Disorders (SUDs). Their research confirms that the impulsivity and dopamine dysregulation inherent in ADHD significantly increase the likelihood of early substance experimentation and long-term addiction.
