How Does GHB Damage Your Liver

The liver is one of the hardest-working organs in the body, and it is also one of the quietest. It does not ache the way a sore muscle aches, and it does not send clear signals the way a broken bone does. It filters the blood, clears away waste, helps the body store energy, makes substances the blood needs to clot, and breaks down chemicals that would otherwise build up and cause harm. It does all of this day and night, without being asked, and most people give it very little thought until something goes wrong. That silence is part of what makes liver damage so dangerous. By the time a person notices that something is wrong, the liver may already have been under strain for a long time.

GHB is a depressant drug, which means it slows down the activity of the brain and the nervous system. It is sometimes called a club drug because it has been used at parties and in nightlife settings, and it is also known for being dangerous because the gap between a dose that changes how a person feels and a dose that can cause unconsciousness or stop breathing is small. That danger is usually talked about in terms of the brain and breathing, and rightly so. But the liver is involved too, because the liver is the organ that has to deal with GHB once it is in the body. Every time GHB is used, the liver is put to work breaking it down, and repeated use keeps putting that work back on an organ that was never meant to carry it so often.

This article explains, in plain words, how GHB damages the liver: what the liver normally does, how it handles GHB, what early warning signs look like, how the harm builds up over months and years, and what happens when the damage becomes serious. It also looks at why the harm is so easy to miss, what makes it worse, and what gives the liver its best chance to recover. It is general information only, not individual medical advice. If you are worried about your liver, or about your use of GHB, a qualified health professional is the right person to talk to.

What the Liver Does Every Day

To understand how GHB harms the liver, it helps to start with what the liver does on an ordinary day. The liver sits on the right side of the abdomen, just under the ribs, and it is about the size of a football. Blood flows through it constantly, carrying nutrients from the food you eat, waste from the body’s normal work, and any chemicals you have taken in, including medicines, alcohol and drugs. The liver sorts through all of this. It keeps what the body needs, stores energy in a form the body can use later, and changes harmful substances into forms that can be passed out of the body in urine or stool.

The liver also makes bile, a fluid that helps the body digest fats, and it makes proteins that help blood clot when you are cut and that carry substances around the body. It helps control blood sugar, keeping it steady between meals, and it stores vitamins and minerals for later use. It is involved in so many jobs that health professionals sometimes call it the body’s chemical factory. Unlike most organs, the liver can repair itself to a remarkable degree. If a small part is damaged, healthy liver cells can grow and take over the work. That ability to heal is real, but it is not unlimited, and it depends on the damage stopping so the repair can catch up.

What makes the liver different from an organ like the skin is that it has very few nerve endings of its own, which means it does not feel pain in the usual way. When the liver is strained or inflamed, a person may feel a dull ache under the right ribs, but often they feel nothing at all in that spot. The signs that do appear tend to be general: tiredness, a poor appetite, nausea, or a vague feeling of being unwell. Those signs are easy to blame on a bad night’s sleep, a busy week, or a stomach bug. That is why liver problems are often found late, sometimes only when a blood test done for another reason shows that something is wrong.

How GHB Reaches and Is Processed by the Liver

When GHB is swallowed, it passes through the stomach and into the bloodstream, and from there it travels to the brain, where it produces its effects, and to the liver, where it is broken down. The liver uses its own chemical tools, called enzymes, to change GHB into other substances that the body can get rid of. This is normal work for the liver. It does the same thing with many medicines and with alcohol. The problem is not that the liver cannot handle GHB at all. The problem is the strain that comes with doing it again and again, especially when the liver is already busy with other work.

The liver breaks GHB down fairly quickly, which is one reason people sometimes think it leaves the body fast and therefore cannot do much harm. That is a misunderstanding. The fact that a substance is cleared quickly does not mean it did no damage on the way through. Each time the liver processes GHB, its cells are exposed to the substance and to the by-products of breaking it down. With occasional exposure, the liver can usually cope and repair itself. With repeated exposure, the repair work never quite finishes before the next round of strain begins, and over time the balance tips from repair towards damage.

There is another factor that makes GHB particularly hard on the liver in real life, and that is that it is rarely used on its own in a tidy, predictable way. People who use GHB often also drink alcohol, and alcohol is itself processed by the liver and is a well-known cause of liver damage. When the liver has to deal with both at once, the strain is greater than either one alone would cause. Some people also use other substances, or take medicines, or have poor diets and little sleep, all of which add to the load on the liver. The liver does not keep a separate account for each substance. It carries the total load, and when that load stays high for weeks and months, the organ begins to wear down.

Early Warning Signs That Are Easy to Miss

The earliest signs of liver strain are often so ordinary that they are easy to dismiss. A person may feel tired all the time, even after a full night’s sleep, and put it down to work or stress. They may lose interest in food, or feel full after eating very little, or feel sick after meals. They may notice a bitter or strange taste in the mouth, or feel queasy in the morning. None of these signs points clearly to the liver, and none of them feels urgent, so most people carry on as before. That is exactly how liver damage gets a head start.

Over time, more specific signs can appear. The skin or the whites of the eyes may take on a yellow tinge, which health professionals call jaundice. This happens when the liver is no longer clearing a yellow substance called bilirubin from the blood properly, and it builds up. Urine may become darker than usual, and stools may become paler, because the flow of bile is disturbed. The skin may become itchy, sometimes all over, sometimes in patches, and scratching does not bring lasting relief. There may be a dull ache or a feeling of tenderness under the right ribs, where the liver sits, or a feeling of fullness there, as if something is pressing from inside.

Other signs are less obvious but just as important. Small cuts and bruises may take longer to heal, because the liver is not making clotting proteins as well as it should. A person may bruise more easily than before. Swelling can appear in the belly or in the ankles, because the liver is struggling to balance fluid in the body. Sleep may become broken, concentration may slip, and a person may feel generally unwell in a way that is hard to describe. Any one of these signs on its own could have many causes, and that is part of the difficulty. But when several of them appear together, and when they keep coming back, they deserve attention, not another excuse.

How Liver Damage Builds Over Time

Liver damage from repeated strain usually develops in stages, and the stages matter because the earlier ones can often be reversed while the later ones cannot. The first stage is often inflammation, where the liver becomes irritated and swollen as it tries to deal with the repeated chemical load. Inflammation is the body’s response to injury, and in the short term it is part of healing. But when the irritation keeps coming, the inflammation becomes chronic, and chronic inflammation slowly changes the structure of the liver itself.

The next stage is the build-up of scar tissue, which health professionals call fibrosis. As liver cells are damaged and repaired again and again, some of the healthy tissue is replaced by tough, fibrous tissue that does not do the liver’s work. A liver with a small amount of scarring can still function reasonably well, because the remaining healthy cells take on extra work. But as the scarring spreads, there are fewer healthy cells left to carry the load, and the liver’s ability to filter blood, make proteins, and control blood sugar begins to fall. This is a slow process. It can take months or years, and during most of that time a person may feel only mildly unwell, if they feel unwell at all.

The most serious stage is cirrhosis, where the scarring is widespread and the liver’s structure is badly distorted. At this point the liver struggles to do its basic jobs, and the effects spread through the whole body. Blood flow through the liver becomes difficult, pressure builds up in the veins around it, fluid collects in the belly, and the risk of serious bleeding and infection rises. Cirrhosis also raises the risk of liver cancer. Not everyone who uses GHB will reach this stage, and it is important to say that plainly, because fear without facts helps no one. But the risk grows with the length and frequency of use, and with the other strains on the liver, and once cirrhosis is established, the damage is very hard to undo. That is why the earlier stages, when change is still possible, matter so much.

GHB, Alcohol and Other Strain on the Liver

GHB rarely acts on the liver in isolation, and the company it keeps makes a real difference. Alcohol is the most common companion, and it is also the most damaging one for the liver. Alcohol is broken down by the same organ, using some of the same chemical pathways, and it causes inflammation and scarring in its own right. When GHB and alcohol are used together, the liver faces two chemical loads at once, and the combined effect is greater than the sum of the two. The person also faces a much higher risk of becoming unconscious and stopping breathing, because both substances slow the brain and the nervous system. That is an immediate danger, but it also matters for the liver, because a body that is starved of oxygen during an episode of unconsciousness puts further stress on all its organs, including the liver.

Other factors add to the load in quieter ways. A poor diet, with too little protein and too few fresh foods, leaves the liver short of the building blocks it needs to repair itself. Lack of sleep and chronic stress affect how the body handles chemicals and how well it heals. Some medicines are also processed by the liver, and using them alongside GHB adds to the work. None of this means that a single night of poor sleep or a single unhealthy meal damages the liver. It means that the liver’s ability to cope is not fixed. It depends on everything else the body is dealing with, and a liver that is already carrying a heavy load has less room left for extra strain.

There is also the question of what is actually in the GHB being used. GHB made outside a regulated setting can vary in strength and can contain other chemicals left over from its production, and the person using it has no reliable way to know what they are taking. Some of those extra chemicals may themselves be hard on the liver. That uncertainty is part of the harm. A person cannot manage a risk they cannot measure, and with unregulated GHB, the strength and the contents are unknown from one occasion to the next. That unpredictability makes every use a gamble, not only for the brain and breathing, but for the liver as well.

When Liver Trouble Becomes Serious

There comes a point where liver trouble stops being a vague feeling of being unwell and becomes a medical emergency, and it is important to know what that point looks like. Yellowing of the skin and eyes that is getting worse, rather than coming and going, is a sign that the liver is struggling to clear waste from the blood. Swelling of the belly that grows over days, especially if it is accompanied by pain, is another. Vomiting blood, or passing very dark stools, can mean bleeding inside the body, which can happen when liver damage raises the pressure in the veins around the liver. Confusion, unusual sleepiness, or difficulty thinking clearly can mean that waste products the liver would normally clear are building up and affecting the brain.

These are not signs to watch and wait on. They are signs to seek urgent medical help. A health professional can run blood tests that show how well the liver is working, and can arrange further checks if needed. Those tests are simple, they are widely available, and they can reveal liver strain long before it becomes visible from the outside. That is one of the most useful things a person worried about their liver can do: ask for a blood test, rather than trying to guess from symptoms alone. The liver’s silence means that symptoms are a poor guide, and a test is a much better one.

It is also worth knowing that liver damage can affect other parts of the body in ways that do not look like liver trouble at all. When the liver cannot make enough clotting proteins, bleeding becomes harder to stop. When it cannot clear waste properly, the kidneys can be affected too. When it cannot store and release energy properly, blood sugar can swing, leaving a person shaky, sweaty and confused. When the liver is badly damaged, infections become more dangerous, because the liver plays a part in the body’s defences. The liver is connected to almost everything the body does, and when it fails, the failure spreads. That is why liver health is not a small, separate topic. It is central to health as a whole.

What Helps the Liver Recover, and What Does Not

The most important thing to understand about the liver is that it can recover, often remarkably well, if the strain is removed early enough. The liver’s ability to regrow healthy cells is one of the strongest healing powers in the body, and many people who stop using a substance that was straining their liver see their blood tests improve over weeks and months. The improvement is not instant, and it is not guaranteed, especially if scarring is already advanced, but it is real, and it is one of the best reasons to stop sooner rather than later. Every week without the extra strain is a week the liver can use to repair itself.

Stopping GHB is the single most important step, and it is also a step that needs care. GHB can cause dependence, and stopping suddenly after regular use can lead to withdrawal symptoms that are unpleasant and, in some cases, dangerous, including confusion, shaking, a racing heart, and seizures. That means stopping should not be done alone and without advice. A health professional can help plan a safe way to stop, and can offer support and monitoring while the body adjusts. That advice is not a formality. It is the difference between a difficult few weeks and a medical emergency, and anyone who has been using GHB regularly should seek it before stopping.

Beyond stopping, the things that help the liver are ordinary but powerful: eating regular, balanced meals with enough protein and fresh food, drinking water, getting enough sleep, and avoiding alcohol and other substances that add to the liver’s load. There is no special food, drink, or supplement that cleanses the liver, whatever advertisements may claim. The liver cleans itself when it is given the chance, and what it needs most is time without extra strain, good food, and rest. Regular check-ups and blood tests let a person and their doctor see whether the liver is improving, and that evidence matters, because it turns a vague hope into something that can be measured.

How Liver Strain Shows Up in Everyday Life

It is one thing to read a list of liver symptoms, and quite another to understand what they feel like in an ordinary week, and that is where the harm of GHB often becomes real for the person living with it. A day that used to begin with energy begins with exhaustion, even after eight hours in bed. Breakfast, which used to be welcome, now sits untouched, because the thought of food brings a wave of queasiness. A flight of stairs that was once taken two at a time now leaves a person breathless and leaning on the banister, not because the lungs have failed, but because the body as a whole is running on less fuel and less clean blood. These are not dramatic events. They are small, daily losses, and they add up into a life that feels smaller and harder than it used to.

Work is often where the change is noticed first, not by the person themselves, but by the people around them. A worker who was once reliable starts missing shifts, or arrives late, or forgets instructions that were given an hour earlier. A student who once kept up with lessons now falls behind, not because the work has become harder, but because the energy and concentration needed to do it are no longer there. The person may blame themselves, and the people around them may blame them too, for laziness or lack of effort, when the real cause is a body that is struggling to do its basic work. That blame makes everything worse, because it adds shame to tiredness, and shame makes a person less likely to ask for help.

Eating and drinking change as well, in ways that are easy to overlook. When the liver is strained, the body may struggle to digest fats, so rich or fried foods can bring on nausea or a heavy, uncomfortable feeling after meals. A person may start avoiding meals, or eating very little, and then wonder why they feel weaker still. Weight can fall, not through any deliberate choice, but because the body is taking in less fuel while still being asked to do the same work. Or the opposite can happen: fluid can collect in the belly, making clothes feel tight and movement uncomfortable, while the person’s arms and legs grow thinner. Either way, the mirror starts to show a person who looks unwell, and that change in appearance can be distressing in itself, especially for someone who is used to looking healthy.

Social life shrinks too, and this is a part of liver harm that rarely appears in medical lists. A person who is tired all the time stops accepting invitations. A person who feels sick after eating stops going out for meals. A person whose skin is itchy or whose eyes look yellow starts avoiding being seen. Slowly, without any single decision to withdraw, the person’s world becomes smaller: home, work, and little else. Friends may assume the person is angry with them, or simply busy, when the truth is that the person is unwell and does not know how to explain it. That isolation matters, because isolation makes it harder to stop using a substance, harder to seek help, and harder to recover. The liver’s damage may be physical, but its consequences reach into every corner of a life.

My Take:

What strikes me most about the liver is how patient it is, and how little thanks it gets for that patience. It works in silence, it repairs itself without being asked, and it carries on even when it is being harmed. I think that patience is part of why liver damage is so often missed. We notice a cough, we notice a sore knee, but we do not notice the organ that is quietly filtering our blood a thousand times a day. When the liver finally does speak, through yellowing skin or swelling or exhaustion that will not lift, it is often speaking late. I wish more people understood that the liver’s silence is not a sign that everything is fine. It is a sign that you have to look for the harm rather than wait to feel it.

I am honest about the fact that GHB has a reputation that is mostly about the brain: the high, the loss of consciousness, the danger of overdose. Those dangers are real, and they deserve every warning they get. But I think the liver deserves a place in that conversation too, because the liver is where the long, slow harm happens. A person can survive a bad night and still be carrying damage they cannot feel. That is what makes GHB different from a substance whose harm is obvious at once. The obvious danger may pass, but the quiet one keeps working, and by the time it shows itself, the choices have narrowed.

The part I find hardest to accept is how easily the early signs are explained away. Tiredness is blamed on work. A poor appetite is blamed on stress. Nausea is blamed on food. Each excuse is reasonable on its own, and that is exactly the problem. The liver does not give you a single, unmistakable warning. It gives you a collection of small, ordinary complaints, and each one is easy to ignore. I think the only honest response to that is to stop explaining the signs away one by one and start adding them up. If you are tired all the time, eating less, feeling sick after meals, and noticing your skin itching or your eyes looking yellow, that is not a run of bad luck. That is a pattern, and patterns deserve a blood test.

I think about the combination with alcohol a lot, because it is so common and so rarely talked about honestly. People treat GHB and alcohol as two separate choices, when in the body they are one load on one organ. The liver does not keep two accounts. It carries the total, and the total is what wears it down. I am not saying this to add blame. I am saying it because understanding the total load is the only way to understand the risk. A person who uses GHB and also drinks is not facing two small risks. They are facing one large one, and the liver is where that large risk lands.

The uncertainty about what is actually in unregulated GHB troubles me as well. When a substance is made without oversight, its strength can vary, and it can contain other chemicals that the person using it knows nothing about. That means the person cannot judge the risk, cannot take a smaller amount with confidence, and cannot know what their liver is being asked to process. I think that uncertainty is itself a form of harm. We make better decisions when we know what we are dealing with, and with GHB, the person using it usually does not. That is not a detail. It is the heart of why this substance is so dangerous.

I want to be clear about recovery, because I think hope matters here, and it is also honest. The liver can heal, and it does heal, often surprisingly well, when the strain stops. I have read account after account of blood tests improving over weeks and months once the substance is gone, and I find that genuinely encouraging. But I also want to be honest about the limit. The liver’s ability to heal is strongest early on, and it weakens as scarring spreads. That is not a reason to give up if the damage is already advanced. It is a reason to act now, while the liver still has healthy cells left to do the repair work. Every week without the strain is a week the liver can use.

Stopping safely is something I feel strongly about, and I want to say it plainly. GHB withdrawal can be dangerous, and stopping suddenly after regular use is not something to attempt alone. I know that asking for medical help can feel difficult, especially when a person is worried about being judged, but a health professional has seen this before, and their job is to help, not to lecture. The safest way to stop is with a plan and with support, and I would urge anyone in that position to get both. Courage is not stopping alone in a bedroom. Courage is walking into a clinic and saying, honestly, what is happening.

I think about families in this story more than anything else, because they are the ones who watch the change and feel powerless to stop it. A partner notices the tiredness, the lost appetite, the yellowing eyes, and does not know what to say. A parent sees their child growing thinner and more exhausted and blames themselves. A child learns to be quiet when an adult is unwell. The liver damage is in one person’s body, but the worry spreads through the whole household. If you are a family member reading this, I would say that your concern is not an overreaction. It is the liver’s silence being heard by someone else, and that matters.

There is a temptation, when writing about a substance like GHB, to make the message simple: just stop, and everything will be fine. I do not think that is honest, and I do not think it helps. Stopping is hard, recovery takes time, and some damage may be lasting. But I also think the opposite message is wrong: that once the damage is done, nothing can be done. Between those two extremes is the truth, which is that stopping gives the liver its best chance, that blood tests can show whether it is working, and that support makes the whole process more likely to succeed. That is not a slogan. It is a practical, hopeful fact, and it is worth holding on to.

Money is a subject people avoid in these conversations, but I think it belongs here, because the cost of GHB is not only the price of the substance. There are the days of work missed through tiredness and illness, the medical appointments, the food that goes uneaten, and the slow shrinking of a life around feeling unwell. When a person stops, that money and that energy come back, slowly, and they can be spent on things that actually make life better. I do not think money is the most important reason to stop, but I think it is a real one, and for some people it is the reason that finally tips the balance.

I also think about young people, because GHB is often used in nightlife and party settings where young people are still deciding who they are. A young person who starts using GHB is not only risking their liver. They are risking the years when their body is still building its reserves, and the damage done in those years can follow them for a long time. Young people deserve honest information, given without judgement, so they can make their own decisions with their eyes open. I think adults owe them that honesty, even when the conversation is uncomfortable.

I think the blood test is one of the most underused tools in this whole story, and I want to say why. People wait for a symptom that proves something is wrong, but the liver does not work that way. It can be under strain for months while a person feels only mildly tired, and the only way to know is to look at the numbers. A simple blood test can show whether the liver’s enzymes are raised, whether it is clearing waste properly, and whether it is making the proteins the body needs. That information is not frightening. It is useful. It tells a person where they stand, and it tells a doctor what to watch. If you are worried about your liver and you have not had a blood test, I think that test is the single most sensible next step you can take.

I am also struck by how much of the harm comes from silence: the liver’s silence, and the person’s silence. The liver does not complain, so the person does not complain either. They do not tell their partner how tired they are, because they think it is just work. They do not tell their doctor about their GHB use, because they are afraid of being judged. They do not tell their friends that they feel unwell, because they do not want to be a burden. Each silence is understandable, and each one makes the harm harder to see and harder to stop. I think the bravest thing a person in this position can do is to break one of those silences: to tell one honest person what is happening. That single conversation can be the beginning of everything else.

Work and study are where most of us prove ourselves, and GHB takes that proving ground away, bit by bit, through the liver’s slow failure. A missed deadline here, a forgotten instruction there, and soon the person feels like they cannot be trusted with important work. That feeling is painful, and it can become a self-fulfilling prophecy, because a person who believes they cannot be trusted stops trying to be trustworthy. I believe the way back is through small, reliable acts: showing up, finishing one task, keeping one promise. Each small act rebuilds trust, first with others, and then, more importantly, with oneself. Recovery is not a grand gesture. It is a series of small, ordinary days done well.

I think about the future a lot when I write about the liver, because the liver is an organ of the future. It stores energy for tomorrow, it clears waste so that tomorrow’s body can work, and it repairs itself so that next year can be better than this one. When GHB damages the liver, it is not only damaging today. It is borrowing against tomorrow, and the debt grows with every use. The hopeful side of that is that the liver’s healing is also a kind of future: every week without the strain is a week invested in the years ahead. A person who stops now is not only protecting today. They are protecting the person they will be in five years, and in ten, and I think that person is worth protecting.

There is one more thing I want to say, and it is about kindness, including kindness to oneself. A person who has used GHB and damaged their liver often carries a heavy load of guilt, and guilt, on its own, does not heal anything. It makes a person hide, and hiding makes the problem worse. I think the healthier response is honesty without cruelty: to look at what happened, to understand why it happened, and to take the next step without punishing yourself for the steps that came before. The liver does not hold grudges. It simply repairs itself when it is given the chance. I think people deserve the same generosity from themselves, and I hope that anyone reading this can offer it to themselves, even if it feels difficult.

I also want to mention the small, everyday signs of healing, because they are easy to miss and they matter more than people think. Food starts to taste better. Sleep becomes a little deeper. The constant tiredness lifts a fraction, and then a little more. A person notices that they can climb stairs without stopping, or that their skin looks a little healthier, or that a cut heals in the time it used to. None of these is dramatic on its own, but together they are proof that the body is repairing itself, and that proof can carry a person through the harder days. Healing is not always visible in a blood test. Sometimes it is visible in an ordinary afternoon, in the simple fact of feeling a little better than yesterday.

Finally, I want to say something about what this article is not. It is not a diagnosis, and it is not a substitute for a doctor. If you have read this far and you recognise yourself, or someone you love, in these pages, the next step is not to worry alone. It is to ask for a blood test, to talk to a health professional, and to get honest information about your own liver, rather than guessing from a list of symptoms. The liver is patient, but it is not invincible. Listening to it early, before it has to shout, is one of the wisest things a person can do, and it is a decision that is never too late to make.

Frequently Asked Questions

What are the main side effects of ghb on the liver?

The main effects on the liver build up slowly rather than arriving all at once. Early on, a person may feel tired, lose their appetite, feel sick after meals, or notice a dull ache under the right ribs. Later signs can include yellowing skin and eyes, darker urine, paler stools, itchy skin, slow healing, and swelling in the belly or ankles. The liver may become inflamed, and with repeated strain, scar tissue can form. The exact effects vary from person to person, and they tend to grow worse with more frequent or longer use.

How quickly can ghb affect liver?

Some effects, such as tiredness and nausea, can appear fairly quickly, while the deeper damage to the liver builds up slowly over weeks, months, or years. The speed depends on the person, how often GHB is used, and what other strain the liver is carrying, such as alcohol. Early signs are often easy to miss, which is why a blood test is a much better guide than symptoms alone.

Can the harm ghb causes to the liver be reversed?

Some of the harm can improve after use stops, as the liver repairs itself over weeks and months. Early inflammation often settles once the strain is removed, and blood tests may improve. Other changes may be lasting, especially after long or heavy use, or once widespread scarring has formed. Early change gives the body the best chance to recover, which is why stopping sooner matters more than stopping later.

Why does ghb affect the liver?

GHB affects the liver because the liver is the organ that breaks it down and clears it from the body. Each time GHB is used, liver cells are exposed to the substance and to the by-products of breaking it down. With repeated use, the repair work never quite finishes before the next round of strain begins. The liver is also affected because it is connected to so many other systems, and because GHB is often used alongside alcohol, which adds its own strain to the same organ.

When should someone seek help about ghb and the liver?

Anyone who notices ongoing problems linked to GHB, such as lasting tiredness, loss of appetite, yellowing skin or eyes, dark urine, swelling, or a dull ache under the right ribs, should talk to a health professional, and should seek urgent help if the yellowing is worsening, the belly is swelling, or there is confusion or vomiting blood. Anyone who finds it hard to stop using GHB should also seek help, and should ask about a safe way to stop, because withdrawal can be dangerous. Earlier help usually means more options and a better outlook.

Where can I learn more about GHB and the liver?

For GHB and the liver, the National Institute on Drug Abuse, the NHS, and the Mayo Clinic publish plain-language information, and their links sit in the Sources section below. A health professional can also answer personal questions about GHB and the liver, and can arrange blood tests that show how well the liver is working.
