The UK is facing a surge in drug-driving offences, many linked to poor mental health, prescription medication and young drivers. In this blog, we explain why awareness and education are key to saving lives this winter.
The Fastest Growing Motoring Offence in the UK
Drug-driving is now one of the fastest-rising road offences in England and Wales. Recent data shows that convictions have more than doubled in under ten years, with fatalities increasing by over 160%.
While drink-driving remains a recognised danger, drug-driving offences are still widely misunderstood and often not taken seriously enough.
At M.A.J Law we’ve seen how stress, anxiety and a lack of awareness can lead ordinary people into extraordinary legal trouble.
The Mental Health Connection
The link between mental health and driving decisions cannot be overstated.
During the winter months, millions experience dips in mood, energy and motivation. Conditions such as Seasonal Affective Disorder (SAD) are triggered by reduced daylight and colder weather, leading to fatigue, poor concentration and impulsive behaviour.
When people are struggling, they often turn to substances - alcohol, recreational drugs, or prescription medication as coping mechanisms. Unfortunately, those same substances impair judgement and reaction times behind the wheel.
Mental health difficulties can make individuals more vulnerable to risky decision-making, including driving after taking drugs, believing they’re “fine to drive”.
Winter Wellbeing and Poor Decision-Making
As daylight hours shorten, the UK sees spikes in both drink-driving and drug-driving arrests. Dark evenings, social isolation, financial stress and exhaustion all play a role.
According to Mental Health UK, one in five adults notice a decline in wellbeing each winter, and many turn to substances for relief. Yet alcohol and drugs worsen depression, anxiety and fatigue, creating a dangerous feedback loop.
At M.A.J Law, we regularly represent drivers who tell us the same story: “I wasn’t thinking straight.” Mental health doesn’t excuse the offence, but it helps explain the human factors that drive it.
Prescription Medication and Drug-Driving: The Hidden Risk
Many people assume drug-driving laws only apply to illegal substances like cannabis or cocaine. In reality, half of the 16 drugs tested for in drug driving cases are prescription-based.
Medications such as:
-
Diazepam
-
Tramadol
-
Morphine
-
Codeine
-
Certain antidepressants
can all impair driving ability. Even if legally prescribed, it’s an offence to drive if a drug affects your safety or exceeds the specified limit in your system.
We often hear from clients who had no idea their medication could trigger a charge, or that mixing prescription drugs with alcohol can push them over the limit.
Did you know? In the UK, while the law sets different thresholds for legal and illegal substances, it remains an offence to drive while impaired by any drug - prescribed, over-the-counter, or otherwise.
If you’re taking medication, always check with your GP or pharmacist before driving. “Prescribed” does not always mean “safe behind the wheel.”

Young Drivers: The New Generation at Risk
Young drivers are at the centre of this rising trend. Studies show that over 25% of under-25s have either driven after taking drugs or been a passenger with someone who has.
Why?
-
Ease of access: Social media and encrypted messaging apps have made buying drugs faster and more discreet than ever.
-
Normalisation: Drug-driving doesn’t carry the same cultural stigma as drink-driving.
-
Lack of education: Many driving courses still focus solely on alcohol.
-
Mental health pressures: Young adults face record levels of stress, anxiety and financial uncertainty - all of which can contribute to substance misuse.
At M.A.J Law, we’ve represented countless young clients who genuinely didn’t understand that one wrong decision could cost them their licence, career, or future.
The Deadly Combination: Low Mood + Substance Use + Driving
When mental health dips, reaction times slow, focus weakens, and self-control declines. Drugs and alcohol intensify those effects.
A driver experiencing low mood or anxiety who takes medication or recreational drugs is far more likely to misjudge their impairment level, especially in winter, when fatigue and darkness already reduce concentration.
The result?
More collisions. More arrests. More lives changed forever.
Why Drug-Driving Still Isn’t Taken Seriously Enough
Despite the alarming statistics, drug-driving is often dismissed as “less serious” than drink-driving. But the reality is stark:
-
Some police forces now record more drug-driving arrests than drink-driving.
-
Many people still believe “legal medication” cannot cause an offence.
-
Public awareness campaigns lag years behind drink-drive messaging.
Until education catches up, people will continue to make uninformed choices, and end up in courtrooms instead of classrooms.
What Needs to Change
-
Mental Health Awareness on the Roads
Drivers need to understand how stress, anxiety and depression affect reaction times, decision-making and concentration. -
Education for Young Drivers
Driving schools and colleges should teach the risks of both drink-driving and drug-driving, not one without the other. -
Prescription Clarity
Pharmacists and GPs should routinely advise patients about driving safety. If a label says “may cause drowsiness,” take it seriously. -
Support, Not Stigma
Many offenders are not criminals, but individuals struggling with mental health and addiction. Early intervention and support can prevent re-offending.
Our Perspective as Motoring Defence Solicitors
As specialist drug-driving solicitors, we fight daily to ensure clients are treated fairly under the law. We also believe in prevention through education.
If you’re feeling low or struggling this winter, reach out for help - to a friend, a GP or a mental-health charity. Don’t reach for something that could end your freedom, your licence, or someone’s life.
Final Word
The rise in drug-driving offences across the UK is more than a legal issue, it’s a social and mental health crisis.
Behind every statistic is a person who made a decision under stress, fatigue, or emotional strain. By tackling the root causes - mental health, medication awareness and education,we can save lives before the blue lights appear.
