To medicate or not Pt 2: what the research actually says
Why ADHD medication gets such a bad reputation, and what the evidence tells us
In my first post, “To Medicate or Not” I shared our family's experience with ADHD medication, the good, the difficult, and the very personal decision my son made to stop. Since then, I've had my own ADHD diagnosis. And with it came a new question: should I try medication myself?
When I started telling people I was considering it, I was surprised by the pushback. Not from doctors. Not from research. From well-meaning people around me.
"But you've managed this long without it." "Are you sure you really need it?" "Isn't that a bit extreme?"
It made me wonder - why does ADHD medication carry so much stigma, when the evidence is actually overwhelmingly positive?
Why do people have such strong opinions about ADHD medication?
I think there are a few reasons:
Misinformation. There's a persistent idea that stimulant medication is somehow dangerous or addictive when used as prescribed. The reality is very different, but the myth sticks.
The "you seem fine" problem. When someone has spent decades masking, compensating, and pushing through, the people around them don't see the cost. They see someone who's coping. What they don't see is the exhaustion, the anxiety, the mental load of keeping it all together.
Medication stigma in general. We don't question someone taking insulin for diabetes or wearing glasses for poor eyesight. But suggest medication for a neurological condition like ADHD, and suddenly everyone has an opinion.
The "natural is better" narrative. There's a well-intentioned but unhelpful belief that we should be able to manage everything through willpower, diet, or lifestyle changes alone. For some people with ADHD, those things help, but they're rarely enough on their own.
So what does the research actually say?
I went looking for evidence. Not opinions, not headlines, actual large-scale studies. And what I found was striking.
It may reduce the risk of premature death
A 2024 study from Sweden's Karolinska Institute, published in JAMA, followed nearly 150,000 people with ADHD. Those who started medication within three months of diagnosis had a 19% lower risk of death from any cause and a 25% lower risk of death from accidents and overdoses over two years [1].
Dr Russell Barkley's research goes further, suggesting that untreated ADHD persisting into adulthood could reduce life expectancy by up to 20 years — and that treatment has the potential to add 9 to 13 years back [2].
That's not a small number.
It reduces the risk of substance abuse, not increases it
This is probably the biggest myth to bust. Many parents worry that giving a child stimulant medication will lead to drug use later in life. The research says the opposite.
A large Swedish study found the rate of substance abuse was 31% lower in people who were prescribed ADHD medication [3]. A US study of 146 million people found a 35% reduction in substance-use events during periods of medication use, with a protective effect lasting up to two years after stopping [4].
No study has ever found that prescribed stimulant medication increases the risk of later substance abuse. Not one.
Fewer driving accidents
For parents of teens who are learning to drive, this one really stood out to me. A US study of 2.3 million people with ADHD found medication was linked to a 38% lower crash risk in males and 42% lower in females [5]. Researchers estimated that one in five accidents involving people with ADHD could have been prevented with medication.
Lower risk of depression
A nationwide study found ADHD medication was associated with a 42% reduced risk of depression three years later [6]. Given how closely ADHD and depression are linked, especially in teens and women, that's significant.
Reduced risky behaviour overall
A study published in the BMJ found ADHD medication was associated with [7]:
- A 17% reduction in suicidal behaviour
- A 15% reduction in substance misuse
- A 12% reduction in transport accidents
- A 13% reduction in criminality
These aren't small, isolated findings. They're consistent patterns across large populations and multiple countries.
But it's not all positive, and that matters too
I want this to be balanced, because that's what parents and adults with ADHD deserve. Honest information, not cheerleading.
Side effects are real. Appetite suppression is one of the most common, and it's the reason my son chose to stop. Sleep difficulties, headaches, and mood changes can also occur, particularly while finding the right medication and dose.
It requires monitoring. In the UK, medication is prescribed under specialist supervision, with regular checks on weight, height, blood pressure, and heart rate. It's not a "take it and forget it" situation. The Karolinska study also found a link between ADHD medication and increased risk of cardiovascular issues, reinforcing the importance of regular check-ups [1].
It doesn't fix everything. Medication can help with focus, impulsivity, and emotional regulation, but it doesn't teach skills. It doesn't build self-understanding. It doesn't repair the damage that years of undiagnosed ADHD can do to self-esteem. That's where coaching, therapy, and education come in.
It's not right for everyone. Some people try medication and it's transformative. Others find the side effects outweigh the benefits. Some prefer to use it situationally: for work tasks, studying, or particularly demanding days; rather than every day. There's no single right approach.
The "you've managed this long" argument
This is the one that got to me personally.
Yes, I've managed. But "managing" isn't the same as thriving. Managing means constantly compensating. It means working twice as hard to achieve what comes naturally to others. It means anxiety, overwhelm, and a nagging feeling that you're always one step away from dropping a ball.
Being diagnosed later in life doesn't mean you don't need support. If anything, it means you've been running on empty for a very long time, and you deserve to find out what it feels like with a full tank.
What I want parents (and adults) to take away
You are not a bad parent for considering medication for your child. You are a parent who is exploring every option.
You are not weak for considering medication for yourself. You are someone who wants to live well, not just cope.
The research is there. Large-scale, peer-reviewed, replicated across countries. Medication doesn't work for everyone, and it should always be one part of a broader support plan, but the evidence for its benefits is strong.
And above all, this is your decision. Not your neighbour's. Not a stranger on the internet's. Yours, made with good information and professional guidance.
Nobody should have to justify choosing evidence-based treatment for a medical condition. Not to anyone.
