Is Cannabis Addictive? Understanding the Reality of Marijuana Dependence in the UK

How common is cannabis addiction across the UK in 2025? Are people really becoming dependent, and if so, what does that dependence actually look like? These are the questions many are quietly pondering as attitudes towards cannabis continue to shift.

Recent years have brought significant changes to how cannabis is perceived and accessed in the UK. On one hand, medical cannabis prescriptions are slowly becoming part of the healthcare conversation. On the other, a growing number of people. Especially young adults. Are seeking help for cannabis-related problems. For anyone wondering whether you can actually get addicted to cannabis, the answer isn’t as simple as a straightforward yes or no.

Let’s cut through the noise and examine the latest facts, using real UK data and expert insights. We’ll explore not only the mechanics of dependence, but also the impact on young people, what’s driving these trends, key warning signs, and most importantly, where to get effective support if you need it.

Latest UK Statistics: Cannabis Addiction and Treatment in 2025

Looking at the numbers, the role of cannabis in UK addiction statistics is unmistakable. According to Priory and GOV.UK data, there has been a clear uptick in individuals seeking treatment for cannabis use over the last few years. Between 2021 and 2022, a 4% increase in new people accessing help for cannabis-related problems was noted. Jump to 2025 and that trend continues, with cannabis representing one of the top substances people seek help for, especially among younger demographics.

To put things into perspective, more than 137,000 adults entered treatment for substance misuse in England within a single year. Among young people in treatment, a staggering 87% reported issues with cannabis, making it by far the most commonly cited drug in this age group. When you look at these figures, it becomes hard to ignore the mounting impact cannabis dependence is having on communities up and down the country.

Some might assume that cannabis, often viewed as a “soft drug”, wouldn’t drive these rates. The data tells a different story. As more people recognise they need support, clinics. Both NHS-run and private. Are recording more cases than ever.

Psychological vs. Physical Dependence: How Cannabis Affects the Brain and Behaviour

You might wonder, “Is cannabis really addictive, or do people just use it habitually?” The reality is more nuanced. Cannabis dependence falls more on the side of psychological addiction, but this doesn’t mean the body is unaffected.

Over time, regular use can change the way the brain’s reward system works. People often find themselves relying on cannabis to cope with stress, anxiety or sleeplessness. This psychological pull is powerful. It’s not just about craving the high, but needing cannabis to feel “normal” or to manage daily life.

Physical dependence can also emerge. Some frequent users, when stopping suddenly, notice withdrawal symptoms: irritability, sleep difficulties, changes in appetite or mood swings. While these may not sound as extreme as withdrawal from substances like alcohol or opioids, they’re real enough to disrupt lives and make quitting challenging.

Clinical experts highlight cannabis use disorder. A genuine medical diagnosis where cannabis use leads to distress or interference with daily responsibilities. This pattern of behaviour goes beyond social smoking or casual experimentation. It’s an escalating cycle rooted in both mind and body, illustrating that addiction isn’t only about physical hook but also about deep-seated habits and emotions.

Signs and Symptoms of Cannabis Addiction: What to Watch For

Recognising the signs of cannabis addiction isn’t always straightforward, especially as social attitudes continue to relax. Still, certain patterns stand out. Among both young people and adults, common warning signs include:

• Struggling to cut down or stop, even after repeated attempts
• Spending significant time and money obtaining or using cannabis
• Letting important activities, hobbies, or relationships slip away
• Using cannabis to cope with stress, boredom, or difficult emotions
• Feeling irritable, anxious, or restless when unable to use
• Repeatedly missing work, school, or other obligations
• Developing memory or concentration problems over time

Teenagers and young adults are especially vulnerable, as their brains are still developing. Many young people in treatment report that cannabis has taken priority over their studies, friendships, or sports. Family members might sense something’s off long before the individual themselves acknowledges a problem. Common red flags include withdrawal from family life, secrecy, and sudden changes in mood or motivation.

Experiencing one or two of these symptoms isn’t rare, especially during stressful periods. It’s the ongoing pattern and the feeling of being unable to control use that truly signals a problem worth addressing.

Factors Fueling Cannabis Misuse in the UK

So why are cannabis-related problems rising, especially now? Changing societal attitudes play a huge role. What was once seen as taboo is now discussed openly among friends, featured in media, and increasingly accepted as part of youth culture. Legal changes around medical cannabis have also fuelled a perception that the drug is largely safe or low risk. Even for recreational use.

The introduction of prescribed medical cannabis in the UK was intended to help patients with serious and chronic health conditions. However, access remains tightly controlled within the NHS. Many turn to private clinics or the black market to source what they believe is “medical” grade cannabis. This blurry boundary between medical and recreational use, along with access to more potent strains, has complicated how the risks are understood by the public.

Easy availability, especially among young people, and shifting perceptions about harms have increased experimentation. At the same time, some individuals use cannabis as a way to self-treat anxiety, depression, or physical pain. Unaware of the potential for dependence that can quietly develop over time.

Ultimately, a mix of changing laws, evolving norms, and easy access. Both legal and illegal. Are creating new challenges in tackling problematic cannabis use across the UK.

Getting Help: Treatment Options for Cannabis Dependence in the UK

What if you or someone you care about is struggling? The good news is that support isn’t just available. It’s expanding as the issue becomes more recognised.

NHS services remain the first port of call for many. Local drug and alcohol services offer assessments, talking therapies, and ongoing support. Treatment can involve cognitive behavioural therapy (CBT), one-to-one counselling, group sessions, or even support for families. While medication options are limited for cannabis dependence itself, integrated care can help tackle issues like depression or insomnia linked with stopping use.

Private clinics and specialist centres such as Priory and Curaleaf offer another avenue, especially for those seeking faster appointments or tailored support. The expansion of digital health tools and remote counselling is also breaking down barriers, enabling more people to access guidance wherever they are.

If you’re unsure where to start, a confidential chat with your GP or a local support service can be the beginning of real change. Even when it feels overwhelming, countless others have taken those first steps towards regaining control and rebuilding confidence.

Remember, asking for help is not a sign of weakness. It’s a mark of awareness and strength.

Final Thoughts: Facing the Truth About Cannabis Addiction

Cannabis use is no longer on the fringes of UK society. More people are using it openly, both for medical reasons and recreation. But with this increased acceptance has come a surge in those needing real support for dependency.

The numbers don’t lie. More people than ever are turning to treatment, and young people are at particular risk. Cannabis addiction is about more than just physical symptoms. It reaches deep into behavioural patterns, relationships, and self-worth.

If you’re worried about your use, or that of someone close to you, know that help is out there. And that positive change is possible. You don’t have to tackle it alone. Take that first brave step by reaching out to a GP, a local support service, or a trusted organisation. Regaining balance and wellbeing can be a reality. One decision at a time.
