Learn / Exploring the Link Between ADHD and Addiction
Attention-deficit/hyperactivity disorder (ADHD) is a serious mental health issue. From the name, it’s easy to think this condition is a set of behavioral problems. But those are just the symptoms. In reality, ADHD comes from a neurochemical imbalance—and it’s remarkably similar to the brain chemistry of addiction.
If you’re considering treatment for ADHD and addiction, you can start by learning how they relate to each other.
People with ADHD have much a higher risk of addiction.1 This is true across age groups, affecting both adults and teens with ADHD.2 Experts agree that the 2 conditions have “a shared biological background.” Specifically, both addiction and ADHD have an impact on dopamine, which is a neurotransmitter.
Dopamine relates to the brain’s reward system.3 This naturally occurring chemical is released when you do something pleasurable. The brain defines “pleasure” broadly: your dopamine might increase when you buy a new pair of shoes, get a job, or eat a cookie. And when an activity feels good, you’re more likely to do it again.
That can be very healthy. For example, you can get dopamine from exercise.4 Your brain is quite literally wired to make you want to work out. But there’s a downside to dopamine. Plenty of activities—like substance use—feel good while doing serious damage to your health. And for people with ADHD, dopamine might already be hard to come by.
If you have ADHD, it may take extra effort to concentrate, sit still, or complete important tasks. This often interferes with relationships, schoolwork and career. In severe cases, people with ADHD can qualify for disability benefits.5 But it also comes with some advantages. Like any other type of neurodivergence, this condition changes the way you see the world. And your unique insight can be a strength.
Biologically, people with ADHD can’t regulate dopamine levels.6 This condition affects at least one of the genes responsible for that process. And that, experts say, “makes it difficult for neurons to respond to dopamine.”
In other words, even if you have healthy dopamine levels, it may not feel that way. So things that “should” be pleasurable might not always feel as good as you want them to.
If nothing feels good enough, it makes sense to go looking for new types of stimulation. This may explain the link between ADHD and risk-taking.7
Drug use falls neatly into this category.
Over time, addiction makes the brain less sensitive to dopamine.8 At first, your brain starts associating drugs with a sense of reward. The act of taking drugs triggers a release of dopamine, whether or not the drug itself does.
As you get used to this repeated flood of dopamine, you’ll feel less satisfaction from taking drugs. This effectively increases your tolerance to the drug, so you need to take more of it to achieve the same result. At the same time, you start feeling less pleasure from other activities. So even if you no longer enjoy the sensation of being high, you might still feel driven to take drugs.
These behaviors quickly become a vicious cycle. Psychiatrist and dopamine expert Dr. Anna Lembke explains that for people in this state, joy is often out of reach. “Now, our drug of choice doesn’t even get us high,” she says. “It just makes us feel normal.”9
But if you have ADHD, addiction recovery might not be enough to break the cycle. You might stop taking drugs, but still feel unsatisfied with your life. In order to heal from these co-occurring disorders, it’s important to find treatment for both of them.
ADHD is often diagnosed in children10 even if you showed no signs of it in childhood.
Because of these complexities, you might need different types of treatment in different stages of recovery. And after you complete rehab, you may benefit from ongoing care for addiction, ADHD, or both. Certain therapies are especially helpful for people with these diagnoses.
Cognitive behavioral therapy (CBT) is a popular treatment for many mental health conditions. And a wealth of data supports CBT as a therapy for ADHD and addiction.11 This framework focuses more on practical skills than it does on emotional processing. Your therapist will teach you coping strategies for dealing with difficult thoughts, urges, social situations, and more. In between sessions, you’ll try them out in your daily life.
As the name implies, integrated cognitive behavioral therapy (ICBT) integrates components of CBT12 and other treatment methods. Patients learn about their condition, practice mindfulness, and learn flexible thinking skills. You’ll use a workbook, and your therapist will give you homework assignments to complete between sessions. This format empowers clients to develop practical skills and put them to use in real-life situations.
ICBT is a highly effective treatment for co-occurring ADHD and addiction.13 One study even found it to be more effective than other forms of CBT. ICBT can also treat post-traumatic stress disorder (PTSD).14 However, like most types of talk therapy, ICBT focuses on mental, emotional, and behavioral issues. Since ADHD is also a neurochemical issue, many people need medical treatment as well.
