What are the Most Common Drugs Used by Teenagers in the UK
by Northern Life
Drug use among teenagers is a topic that concerns parents, teachers, healthcare professionals, and policymakers across the United Kingdom. While most young people do not regularly misuse substances, experimentation during adolescence is not uncommon.
This is why it’s super important to know which drugs are most commonly used by teenagers, why they use them, and the potential risks involved, which is essential for early intervention, education, and harm reduction.
Why Teenagers Experiment with Drugs
Adolescence is a period of curiosity, social pressure, and emotional development. Teenagers may be drawn to substances for several reasons, including:
- Peer influence and a desire to fit in
- Stress linked to school, exams, or social media
- Curiosity and experimentation
- Mental health challenges such as anxiety or low mood
- Easy access to substances at home or socially
While experimentation does not always lead to dependency, early drug use can increase the risk of long-term physical, emotional, and social harm.
The Most Common Drugs Used by Teenagers in the UK
Below is an overview of substances most frequently associated with teenage drug use, based on national surveys and public health data.
1. Alcohol
Alcohol remains the most commonly used substance among teenagers, despite age restrictions.
Key points:
- Often consumed at parties or social gatherings
- Binge drinking poses serious health risks
- Linked to accidents, risky behaviour, and poor mental health
Although many view alcohol as “normal”, teenage brains are still developing, making them more vulnerable to its effects.
2. Cannabis
Cannabis is the most widely used illegal drug among teenagers in the UK.
Risks include:
- Impaired memory and concentration
- Increased risk of anxiety, paranoia, and low motivation
- Potential impact on brain development with frequent use
Stronger cannabis strains available today may increase these risks compared to previous decades.
3. Vapes and Nicotine Products
Vaping has risen sharply among young people, often perceived as harmless.
Important facts:
- Many vapes contain nicotine, which is highly addictive
- Nicotine can affect attention, learning, and mood
- Some devices contain unknown or unregulated chemicals
Teenagers who vape are also more likely to later experiment with cigarettes or other substances.
4. Prescription Drugs
Some teenagers misuse prescription medications, particularly when shared by friends or family.
Commonly misused types include:
- Painkillers (such as codeine-based medicines)
- Anxiety or sleep medications
- Stimulants prescribed for ADHD
Misuse can lead to dependency, overdose, or dangerous interactions with other substances.
5. MDMA (Ecstasy)
Although less common than alcohol or cannabis, MDMA is sometimes used by older teenagers, particularly in party or festival settings.
Potential dangers:
- Dehydration or overheating
- Mood crashes and anxiety
- Unknown strength or contamination of pills

Warning Signs of Drug Use in Teenagers
Parents and carers should stay alert to possible indicators, such as:
- Sudden changes in mood or behaviour
- Declining school performance
- Secretive behaviour or withdrawal from family
- Physical signs (red eyes, unusual tiredness, smell of substances)
Early, non-judgemental conversations can make a significant difference.
When to Seek Support
If substance use begins to affect a teenager’s mental health, education, or relationships, professional help may be needed. Support can range from school-based services and counselling to structured treatment options, including rehab for teenagers in more serious cases.
Teenage drug use in the UK is a complex issue influenced by social, emotional, and environmental factors. If you learn to understand which substances are most commonly used and find the early warning signs, parents and communities can respond with empathy, education, and appropriate support.
Open communication, accurate information, and early intervention remain the most effective tools for helping young people make safer, healthier choices as they grow.
