Heroin addiction is a severe health crisis in the UK that quietly devastates lives and families. In 2023, England and Wales recorded 5,448 drug‑poisoning deaths, nearly half of which involved opiates like heroin or morphine.
This shocking figure reflects real people trapped in cycles of dependency, struggling with guilt, isolation, and the common fear of withdrawal. If you’re wondering if heroin may be harming you or a loved one, you’re not alone. Read on to find out what addiction to heroin means, the signs and symptoms, and the next steps.
What is heroin?
Heroin is a Class A controlled drug under the Misuse of Drugs Act 1971, which means it is illegal to possess, supply, or manufacture. It is made from morphine, a substance naturally found in the opium poppy plant, and usually comes in one of two primary forms:
- A white or brown powder
- A sticky, black form known as black tar heroin
People use heroin in different ways, such as injecting it, smoking it, or snorting it. Whichever way it’s taken, the drug reaches the brain almost instantly, bringing on a sudden rush of intense pleasure. That high can quickly melt into a heavy, dream-like calm, and for a short while, it may feel as if worries or pain have faded into the background. However, this relief is only temporary, and chasing it can affect health, relationships, and shape the future.
Why is heroin so addictive?
If you’ve used heroin yourself or seen someone you care about struggle with it, you’ll know how quickly it can go from an occasional escape to something that feels impossible to live without. Heroin use disorder is a misunderstood coping mechanism that isn’t about weakness or a lack of willpower; it’s a powerful drug that significantly alters the brain.
Once heroin enters the body, it’s converted into morphine, which binds to the brain’s opioid receptors. This releases dopamine, a hormone that stimulates pleasure. Someone going through physical pain or emotional distress can feel compelled to use more of the drug to hold onto this euphoric feeling. For many people, heroin use begins not as a pleasure, but as a way of coping with deep-rooted trauma, grief, or unresolved emotional pain. It can feel like the only escape from overwhelming memories or feelings. Over time, there is a need to take the drug more often to suppress any unwanted thoughts or emotions, even though the relief is only temporary. This is known as heroin addiction.
Repeated use of heroin results in the brain learning to associate heroin with relief and euphoria, making you want to experience it again. Over time, you may experience the following:
- Tolerance develops, meaning you need more heroin each time to feel the same impact
- Dependence sets in, and your body starts to rely on heroin to feel “normal”
- Withdrawal symptoms, which can be physically and emotionally overwhelming if you try to cut back or stop, pull you back into the cycle of heroin abuse to ease any discomfort
When does heroin addiction become life-threatening?
Abusing heroin doesn’t just affect the person using the drug in obvious ways; many of its dangers can be hidden beneath the surface until they become overwhelming, and professional support is needed.
These effects can show up both physically and emotionally, changing how someone feels in their own body and how they relate to the people around them. Recognising the signs in yourself or someone you care about is the first step toward understanding and seeking help.
Physical and behavioural signs of heroin addiction in yourself
- Unsuccessful attempts to stop, even with genuine willpower
- Emotional and physical ill-health without access to heroin
- Disruptions in sleep, appetite, or energy, ranging from insomnia to exhaustion
- Obsessive thinking about the next heroin fix, even if it causes a personal or financial burden
- Feelings of overwhelming guilt, shame, or self-loathing, often pushing use into secretive behaviours
Spotting signs in someone else:
- Injection marks or visible scarring, often disguised under long sleeves or makeup
- Hostility or defensiveness when someone mentions possible heroin use
- Impacted work or personal responsibilities, such as missed shifts, broken commitments, and self-isolation
Destigmatising addiction to heroin
Heroin use disorder is one of the most misunderstood health issues in the UK, with stigma and misinformation often making it harder for people to seek support. Opioids remain the leading reason individuals enter treatment services, yet many myths continue to fuel judgement and prevent open conversations.
It’s important to recognise that addiction to heroin is often less about chasing a high and more about escaping something painful. Many people turn to heroin to numb trauma, block out distressing thoughts, or soothe mental health struggles. By separating the facts from fiction, we can better understand heroin dependency, its impact, and why compassion and evidence-based knowledge are so important.
Myth 1: Heroin addiction only affects people from disadvantaged backgrounds.
Fact: Heroin use disorder does not discriminate. It develops as a coping mechanism to drown unwanted feelings and trauma. While poverty and social inequality increase risk, many people from stable jobs, families, and higher-income backgrounds also develop heroin problems.
At The Haynes Clinic, we have seen people from all walks of life change their abusive relationship with heroin.
Myth 2: If someone wants to give up heroin badly enough, they can just stop.
Fact: Heroin changes brain chemistry in ways that create powerful cravings and severe withdrawal symptoms. This makes quitting without support extremely difficult, even for those who desperately want to. It takes a community of support and intricate therapy to help people overcome this reliance and move to healthy coping mechanisms to deal with feelings of stress or anxiety.
Myth 3: Heroin users always end up overdosing.
Fact: While heroin overdose remains a major risk, many people do recover and rebuild their lives. With the right medical and psychological support, long-term recovery is absolutely possible, as long as the person is willing and ready to change.
Myth 4: Heroin use only harms the person taking it.
Fact: The ripple effect of heroin reliance touches families, workplaces, and entire communities. It can strain relationships, cause financial hardship, and place heavy burdens on healthcare and social services. Addiction cannot be treated unless the person abusing heroin decides they want to help, which can cause devastating feelings of helplessness and worry for loved ones when they see someone consumed by the drug.
Myth 5: If you don’t inject heroin, it’s safer.
Fact: Smoking or snorting heroin can still lead to overdose, dependency, and serious health consequences. While injecting carries unique risks like collapsed veins and blood-borne infections, all methods of use are dangerous and potentially life-threatening.
The hidden dangers of heroin
Heroin may feel like it offers short-term relief, but the harm it causes often runs much deeper than most people realise. Beyond the immediate high, the drug can silently damage the body, disrupt mental health, and alter the brain in lasting ways. These dangers often remain hidden until they begin to affect everyday life in serious, sometimes irreversible, ways.
Physical health hazards
Repeated injections damage veins and increase the risk of:
• Collapsed veins, abscesses, or cellulitis
• Blood-borne infections like HIV and hepatitis C from shared needles
Cardiac and systemic infections
Heroin dramatically raises the risk of endocarditis, a dangerous infection of the heart’s lining. In some regions, endocarditis hospitalisations tied to heroin have soared by over 400%.
Organ damage
Heroin and its impurities can harm your liver and kidneys, particularly over long-term use
Mental health and cognitive decline.
Heroin often coexists with anxiety, depression, and trauma, and is used as a way to block out any negative thoughts. Withdrawal can make these feelings unbearable.
Brain structure influences
Chronic use can degrade white and grey matter in brain regions critical for decision-making and impulse control.
Overcoming heroin addiction
Noticing the signs of heroin use in yourself or someone you love can feel overwhelming. But taking the time to learn, to question, and to seek answers is already a powerful first step toward change.
If you’re reading this and relate to any signs, know this: you’re not alone and help is available. Behind every one of the heroin treatment statistics is a person who made the brave choice to reach out for help, often after years of struggle. Recovery isn’t easy, but it is possible. With the right support, people do rebuild their lives, heal relationships, and find hope again.

Heroin addiction FAQs
How long does heroin stay in your system?
Heroin itself leaves the bloodstream quickly, but it breaks down into morphine and other metabolites that can be detected for longer. Depending on the test, heroin use may be detectable in urine for 1 to 4 days, in blood for up to 6 hours, and in hair for up to 90 days.
Can someone function normally while addicted to heroin?
Some people with heroin addiction may seem to function at first, balancing work, family, or social life (otherwise known as ‘functioning addiction’.) However, the drug’s impact on the brain and body builds over time and what looks manageable early on quickly unravels, making long-term functioning impossible when reliant on heroin.
