Study Links ADHD Medication to Lower Risks of Substance Misuse, Accidents and Criminal Behaviour
A Swedish study finds ADHD medication reduces risks of suicide, substance misuse, accidents and criminal behaviour by up to 25%, highlighting its broader life benefits.
A new study in Sweden indicates that drug treatment for ADHD can greatly lower the risk of substance misuse, suicidal behaviour, transport accidents and criminal acts among patients aged 6 to 64.
Study Design and Participants
The research, published in the British Medical Journal, tracked 148,500 individuals diagnosed with ADHD. Of these, 57% received medication—predominantly methylphenidate (Ritalin).
Key Findings
- 17% reduction in first-time suicidal behaviour
- 15% reduction in first-time substance misuse
- 12% drop in first-time transport accidents
- 13% decrease in first-time criminal behaviour
When considering repeat events, medication was linked to:
- 15% fewer suicide attempts
- 25% less substance misuse
- 4% fewer accidental injuries
- 16% fewer transport accidents
- 25% less criminal behaviour
Broader Benefits and Challenges
Prof Samuele Cortese of the University of Southampton noted that these findings provide critical data on risks avoided when ADHD is treated. Medications may curb impulsivity and improve focus, reducing accidents and aggressive incidents.
However, the study cannot fully exclude factors such as genetic background, lifestyle choices and ADHD severity. Access to timely assessment and medication remains a challenge in many regions, with long waiting lists in places like the UK.
Experts warn that untreated ADHD often leads to self-medication, mental health decline and involvement with the criminal justice system.
ADHD medication is shown to significantly lower incidences of self-harm, substance misuse, accidents and crimes, demonstrating benefits beyond managing core symptoms.
