What Happens to Your Body When You Stop Using Nitrous Oxide

Nitrous oxide is a colourless gas that is used in medicine as a painkiller and a sedative, and it is also sold in small metal canisters for whipping cream. When it is breathed in for fun, it gives a very short feeling of lightness, laughter or floating, and then it fades within a minute or two. That short high is one reason people use it again and again in the same evening, sometimes breathing in dozens of canisters. What many people do not realise is that the gas does more than change how you feel for a minute. With repeated use it interferes with vitamin B12, a vitamin the nerves and the blood depend on, and it can damage the nerves in the legs, hands and spine. The damage often builds up quietly, and it may only become obvious when walking, balance or feeling in the feet starts to change.

Stopping is the single most important step, because every further use adds to the damage. Yet stopping does not switch the body back to normal overnight. Some things improve quickly, such as the dizziness and confusion that follow each use, but nerve damage heals slowly, and some of the tiredness, low mood and poor sleep that follow heavy use can linger for weeks or months. This article explains, in plain words, what the body goes through after nitrous oxide use stops: why the gas harms the nerves, what the first days and weeks often feel like, which changes tend to improve and which may take much longer, and when it is important to seek professional help. It is general information only, not individual medical advice.

Why Nitrous Oxide Harms the Nerves

The main reason nitrous oxide causes lasting harm is its effect on vitamin B12. Vitamin B12 is needed to keep the protective coating around nerves healthy. That coating, called myelin, works like the plastic around an electric wire: it helps signals travel quickly and cleanly from the brain to the rest of the body. Nitrous oxide switches off the active form of vitamin B12 in the body. One use does not usually cause lasting trouble, because the body has stores of the vitamin. But repeated use, especially over weeks or months, drains those stores and blocks the vitamin from doing its job. When the coating around the nerves is starved in this way, the nerves start to send weak, confused or painful signals.

The nerves most often affected are the long ones that run down the spine and into the legs and feet. That is why the classic warning signs are tingling or numbness in the toes and fingers, a feeling of pins and needles that does not go away, weakness in the legs, and trouble with balance. Some people describe it as walking on cotton wool, or feeling as if their feet are not quite connected to the ground. Others find that their legs feel heavy, that they trip more often, or that they need to hold on to furniture or a wall to walk safely. In more serious cases, the bladder and bowel can also be affected, and the hands can become clumsy, so that buttoning a shirt or holding a cup becomes difficult.

Vitamin B12 is also needed to make healthy red blood cells. When it is low, the blood can become anaemic, which means it carries less oxygen around the body. That adds to the tiredness and weakness, and it can make a person feel short of breath when they climb stairs or walk uphill. A blood test can show whether B12 is low and whether anaemia is present, which is one reason a health professional is the right person to talk to if these symptoms appear. Taking a B12 tablet on your own is not a safe substitute for that check, because the damage may already be advanced, and other causes need to be ruled out.

The First Days After Stopping

The first thing many people notice after stopping is that the short, dizzy highs are gone, and with them the confusion that followed each use. During heavy use, a person may feel light-headed, giggly or detached for a few minutes at a time, and then dull and flat in between. Once the gas is out of the system, which happens quickly because it leaves the body fast, that cycle stops. Thinking usually feels a little clearer within a day or two, and the risk of fainting, falling or having an accident while intoxicated falls away at once. That is a real and immediate benefit of stopping, even if other problems take longer to fade.

The first days are not always comfortable, though. People who used heavily often report trouble sleeping, vivid or strange dreams, irritability, restlessness and low mood in the days after they stop. Anxiety is common too, partly because the body is adjusting and partly because the habit itself has left a gap in the evenings or in social situations where the gas was used. Cravings can appear suddenly, especially in places or with people linked to using. These feelings are usually strongest in the first week and then ease, but they can return in waves, and they are one reason people find it helpful to talk to someone, to change their routine, or to get support rather than trying to manage alone.

There is also a practical danger that can appear in the early days, and it is worth understanding clearly. A person who already has nerve damage may not notice the full extent of it until they are sober and moving around normally. Numb feet can make it hard to feel a cut or a blister, and poor balance raises the risk of a fall, especially on stairs or in the dark. Weak legs can give way without warning. That is why it is sensible to move carefully in the first weeks, to wear firm shoes, to keep rooms clear of clutter, and to ask for help with tasks that need steady footing, such as climbing a ladder. None of this is a reason to keep using. It is a reason to take the recovery period seriously.

Tingling, Numbness and Weakness

The nerve symptoms are usually the slowest part of the story, and they are the part that worries people most. Tingling in the feet and hands may be the first sign, and it can feel like a faint buzzing or a prickling that comes and goes. As the damage grows, the tingling can become constant, and parts of the foot or hand may go numb. Numbness is dangerous not only because it is uncomfortable, but because it removes the body’s warning system. A person may not feel a stone in their shoe, or hot water that is too hot, and small injuries can go unnoticed and become infected.

Weakness tends to follow the same pattern. It often starts in the legs, and it may show up as difficulty climbing stairs, getting up from a low chair, or walking any distance without resting. Some people notice that their legs feel stiff, or that they drag a foot when they are tired. Others find that their grip weakens, so that jars are harder to open and handwriting becomes shaky. These changes are frightening, and it is understandable to want a quick fix. There is no quick fix for damaged nerves. Nerves regrow very slowly, at a pace measured in millimetres a month, and the spinal cord itself recovers even more slowly than the nerves in the limbs.

That slow pace does not mean nothing improves. Many people find that the tingling eases over weeks and months after stopping, and that strength and balance gradually return, especially if the damage was caught early. The improvement is rarely a straight line. Some weeks feel better and some feel worse, and progress can be hard to see from day to day. Keeping a simple note of what you can do each week, such as how far you can walk without stopping, can make the slow improvement visible. If symptoms are getting worse after stopping, or if new weakness, bladder trouble or severe pain appears, that is a sign to seek medical attention promptly rather than waiting.

Balance, Walking and Everyday Movement

Balance is one of the functions most affected by nitrous oxide damage, and it is also one of the most disruptive in daily life. The body keeps its balance using signals from the feet, the eyes and the inner ear, and the signals from the feet travel up the spinal cord. When that cord is damaged, the brain receives a blurred picture of where the feet are, and walking becomes unsteady. People often describe feeling wobbly in the dark, because without sight to compensate, the blurred signals from the feet are not enough. Turning quickly, walking on uneven ground, or standing with eyes closed can all become difficult.

Everyday movement changes in ways that are easy to overlook until they add up. Getting out of bed in the morning may need more care. Standing in a queue can become tiring. Carrying shopping, climbing onto a bus, or walking to work can all take longer and need more effort. Some people start to avoid going out, not because they do not want to, but because they are afraid of falling. That avoidance can shrink a person’s life, and it can add to low mood and loneliness. Gentle movement, as advised by a health professional, can help keep the muscles strong and the joints flexible, but it should be done carefully and with support nearby at first.

It is also important to understand that a fall during this period is not a minor event. A fall can cause a broken bone, a head injury, or a loss of confidence that lasts long after the bruises heal. That is why the home matters: good lighting, handrails on stairs, a non-slip mat in the shower, and shoes that fit well and grip the floor. These are small changes, but they reduce the risk of a serious accident while the nerves are healing. They also give a person more freedom to move around safely, which helps both the body and the mood.

Sleep, Mood and Thinking After Stopping

Sleep is often disturbed both during heavy use and in the weeks after stopping. Some people find it hard to fall asleep, others wake in the night, and many report vivid dreams or nightmares that leave them tired in the morning. Poor sleep then makes everything else harder: thinking feels slower, patience wears thin, and the urge to use again can grow stronger when a person is exhausted. The pattern is a loop, and breaking it takes time. A regular bedtime, a dark and quiet room, and avoiding screens late at night are simple habits that help the body relearn a normal rhythm, but they do not work overnight.

Mood is closely tied to sleep, and it is also affected directly by the changes in the body. Low mood, anxiety and irritability are common after stopping, especially if the gas was used to cope with stress or to feel part of a group. When that coping tool is gone, the original stress is still there, and it can feel sharper than before. Some people also feel flat or empty, as if ordinary pleasures have lost their colour. That flatness usually lifts gradually as sleep improves and as the body’s chemistry settles, but it can take weeks. Talking to a friend, a family member or a professional can make that period easier to bear, and it is not a sign of weakness to ask for that help.

Thinking and memory can also be affected. During heavy use, the brain is repeatedly starved of oxygen for short periods, and vitamin B12 shortage adds to the strain. People may notice that they forget appointments, lose track of a conversation, or find it harder to concentrate on reading or work. These problems usually improve after stopping, and the improvement often follows the same slow timeline as the nerve recovery. Writing things down, keeping a simple routine, and tackling one task at a time can reduce the frustration while the brain recovers. If confusion is severe, or if a person becomes very drowsy or hard to wake, that needs urgent medical attention.

How Recovery Works Over Weeks and Months

Recovery after stopping nitrous oxide is not a single event but a gradual process, and it helps to know what to expect. In the first week, the gas is gone from the body, thinking is clearer, and the risk of accidents while intoxicated disappears. Over the next few weeks, sleep and mood often begin to settle, and the tingling may start to ease, although it can also feel more noticeable at first as the nerves begin to wake up. Over two to three months, many people notice real gains in strength and balance, and blood levels of B12, if treated under medical care, begin to return toward normal.

After three to six months, the picture becomes clearer. Some people recover almost fully, especially if they stopped early and the damage was mild. Others are left with some numbness, weakness or balance trouble that improves only slowly, or that remains as a lasting reminder. The difference depends on how much and how long a person used, how early the damage was noticed, and whether they received medical care and stopped completely. Continuing to use, even occasionally, slows recovery and can make the damage worse, which is why complete stopping matters more than cutting down.

Medical care plays a central part in this process. A health professional can check B12 levels, look for anaemia, test nerve function, and arrange the right treatment and follow-up. That treatment is a medical matter, and it should be decided by a clinician who can see the full picture, not by guessing from an article. What a person can do for themselves is to stop using, to eat a balanced diet, to keep moving gently as advised, to protect their feet and their balance, and to keep their follow-up appointments. Recovery is slow, but it is real, and it starts the day use stops.

The Risks That Stop With You

One of the most encouraging facts about stopping is that some risks fall away immediately. Nitrous oxide displaces oxygen in the lungs, and when a large amount is breathed in at once, especially from a balloon or a bag, the brain can be starved of oxygen. That can cause fainting, fits, or in rare cases serious injury or death. There is also a risk of frostbite from the cold gas escaping from a canister, and of accidents caused by sudden dizziness. All of those risks end when use stops. That matters, because it means the decision to stop protects a person from the most sudden and severe harms straight away, even while the slower nerve recovery is still under way.

There are also risks to other people that stop with you. A person who is intoxicated may drive badly, make poor decisions, or be unable to look after a child. Stopping removes those risks too. It also removes the cost of buying canisters, which can add up to a large amount over months, and it removes the worry of being found out at work or at home. These may seem like small things next to nerve damage, but they are part of the real, everyday burden of use, and lifting them can make life feel lighter and more manageable.

Finally, it is worth saying plainly that the damage nitrous oxide causes is not a punishment, and it is not a sign of a bad person. It is the result of a gas that blocks a vitamin the nerves need, and the body does not know or care why the gas was used. What matters now is what happens next. Stopping gives the body its best chance to heal, and seeking help gives that chance the support it needs. The earlier both happen, the better the outlook tends to be.

Food, Energy and the Body’s Slow Repair

Food matters more during recovery than most people expect, because the body is trying to rebuild what the gas took away. Vitamin B12 comes mainly from animal foods such as meat, fish, eggs and dairy, and a person who eats little of these may already have low stores before they ever breathe in nitrous oxide. That does not mean a special diet can fix nerve damage on its own, and it certainly does not mean that eating a particular food is a treatment. It means that a balanced diet, with enough protein, vitamins and minerals, gives the body the raw materials it needs for the slow work of repair. A health professional can check whether B12 or other vitamins are low and decide what, if anything, is needed, because the right approach depends on blood results, not on guesswork.

Energy is another part of the picture that people often misunderstand. Tiredness after stopping is not laziness, and it is not a sign that a person is not trying hard enough. It comes from several directions at once: anaemia means less oxygen reaches the muscles, poor sleep means the body never fully rests, and the nerves themselves use energy inefficiently when they are damaged. A person may feel exhausted after a short walk, or after a morning of ordinary chores, and that exhaustion can be discouraging. Gentle, regular activity, as advised by a clinician, helps the muscles stay strong without overloading them, and rest in between matters just as much as the activity itself. Pushing through exhaustion rarely speeds recovery. It usually makes the next day worse.

The body’s repair work is invisible, which makes it hard to trust. There is no daily sign that the protective coating around a nerve is growing back, no visible change to point to and say that today is better than yesterday. That invisibility can make a person feel as if nothing is happening, and that feeling can tempt them to give up on the small daily habits that support recovery: eating regularly, sleeping at regular hours, keeping follow-up appointments, and moving gently. Yet those habits are the foundation of the repair, even when their effect cannot be seen. Recovery is not a single dramatic improvement. It is the accumulation of many small, ordinary days in which the body was given what it needed and not given more damage to repair.

It is also worth understanding that other health problems can make recovery harder, and they deserve attention in their own right. A person who already has diabetes, a thyroid problem, or a poor diet may find that their nerves recover more slowly, because those conditions affect the nerves and the blood supply too. Smoking, heavy drinking and poor sleep add further strain. None of this is a reason to blame the person. It is a reason to look at the whole picture with a health professional, so that the things that can be improved are improved, and the recovery is given the best possible chance. The body does not heal in separate compartments. It heals as a whole, and everything that supports general health supports nerve recovery too.

Finally, the social side of eating and energy matters more than it sounds. Meals are often shared, and a person who is tired, unsteady or low in mood may start eating alone, skipping meals, or relying on quick, low-quality food because cooking feels like too much effort. That drift is understandable, and it is also a quiet way for recovery to stall. Eating with family or friends, even a simple meal, helps in two ways at once: it makes regular eating more likely, and it keeps the person connected to the people around them. Connection and nourishment are not separate parts of recovery. They are the same work, done in different forms, and both deserve the same care.

One more practical point deserves a place here, and it is about driving. A person whose feet are numb and whose balance is poor should not assume they are safe to drive. The feet control the pedals, and if feeling in the feet is dulled, braking can be slower or less precise, especially in an emergency. Reaction time can also be slower when sleep is broken and thinking is foggy. It is wiser to avoid driving until a health professional says it is safe, and to arrange lifts or public transport in the meantime. That may feel inconvenient, and it may feel like another freedom lost, but it protects the driver and everyone else on the road, and it removes one more source of worry while recovery is under way.

My Take:

I think the most important thing to understand about nitrous oxide is how ordinary it looks. It comes in small silver canisters, it is used in kitchens, and it gives a laugh that lasts less than a minute. Nothing about it looks dangerous. That ordinariness is exactly why it catches people out. A person does not set out to damage their nerves. They take a balloon at a party, they laugh, and they take another. The damage does not announce itself with pain or with a warning. It builds quietly, one canister at a time, until one morning their feet feel strange, or they stumble on flat ground, and suddenly the joke is over.

What stays with me is the cruelty of the timing. The nerve damage often becomes obvious only after the fun has faded, when the person has already stopped or cut down, and they expect to feel better. Instead, they feel worse, or they feel the same, and they wonder whether stopping was pointless. It was not pointless. Stopping is what gives the nerves a chance to heal at all. The fact that healing is slow does not mean it is not happening. It means the body is doing difficult, quiet work, and that work deserves patience, not despair.

I am struck by how much of this harm comes down to a single vitamin. Vitamin B12 is not exotic or rare. It is in ordinary food, and most people get enough of it without thinking. Nitrous oxide switches it off, and the whole nervous system pays the price. That simplicity makes the harm easier to understand, and it also makes it harder to accept, because it feels as if something so small should not cause so much trouble. But the body is a system of small things, and when one of them fails, the effects spread. The tingling in the toes is not a small symptom. It is a signal that the wiring itself is under strain.

The balance problems worry me more than almost anything else in this article, because they are so easy to underestimate. A person who cannot trust their feet cannot trust their independence. They hesitate at the top of the stairs. They avoid going out after dark. They stop visiting friends. Life gets smaller, not because they have lost interest, but because movement has become frightening. I think that loss of freedom is one of the real costs of nitrous oxide, and it is a cost that does not appear on any list of side effects. It is lived, day by day, in a home that suddenly feels full of hazards.

Sleep is another part of the story that I think deserves more attention. People talk about tingling and weakness, but they talk less about the nights. A person who cannot sleep well cannot think well, cannot work well, and cannot cope well. The vivid dreams, the broken nights, the exhaustion in the morning, all of it makes recovery harder, because recovery needs rest. I would say to anyone in this position that sleep is not a luxury to be earned after you get better. It is part of getting better, and it is worth protecting with the same seriousness as any other part of the recovery.

Mood is the part I find hardest to write about honestly, because it is so easy to sound as if I am blaming the person. I am not. Low mood after stopping is not a failure of character. It is the body adjusting, and it is the loss of a habit that filled a social gap. Many people used nitrous oxide with friends, at parties, in moments of laughter. Stopping can feel like stepping away from that group, and that loneliness is real. I think the answer is not to go back to the gas, but to find other ways to be with people, other things to laugh about, other evenings that do not end with numb feet. That takes effort, and it takes time, but it is possible, and it is worth doing.

I also think about the people who used nitrous oxide without ever knowing the risk. The canisters are sold openly, the gas is used in dentistry, and the warnings, where they exist, are often small or easy to miss. A young person who sees friends using it may reasonably assume it is safe, because if it were dangerous, surely someone would have said so. That assumption is understandable, and it is wrong, and I think that is a failure of information, not of the young person. More people need to know that this gas can damage nerves, and they need to know it before they start, not after their feet go numb.

If I could say one thing to a person who has just stopped, it would be this: do not judge your recovery by a single day. There will be days when the tingling feels worse, days when you trip, days when you feel flat and wonder whether anything is improving. Those days do not mean the recovery has failed. They mean the nerves are healing unevenly, which is how nerves heal. Look at weeks, not days. Write down what you could do this week that you could not do last month. That small record is often the only honest measure of progress, and it can be surprisingly encouraging.

I would also urge anyone with numbness, weakness or balance trouble to see a health professional and to say plainly what they have been using. I know that is hard. People worry about being judged, or about the information being shared. But a doctor cannot help with a problem they do not know about, and nerve damage is not something to guess at. The check is simple, the blood test is simple, and the earlier the problem is found, the better the chance of recovery. Shame is a poor reason to risk permanent damage, and most health professionals have heard this story before and will treat it as a health matter, which is what it is.

The cost of the canisters is another thing I think about, because it is concrete and it adds up. A person who uses dozens of canisters in an evening, several evenings a week, can spend a large amount of money in a month, and over a year that money could have paid for something that lasts. I do not say this to add guilt. I say it because money is one of the few measures that makes the scale of the habit visible. When use stops, that money stays in the pocket, week after week, and that is a real, weekly reward that a person can see and feel. It is a small thing, but small rewards matter when the bigger rewards, like feeling in your feet, are slow to arrive.

I am honest about the fact that some damage may not fully reverse, and I do not want to pretend otherwise. Nerves heal slowly, and the spinal cord heals more slowly still. A person who used heavily for a long time may be left with some numbness or unsteadiness, even after they have stopped and received care. That is a hard truth, and it is worth saying plainly, because false hope is no help to anyone. But it is also true that many people improve a great deal, that stopping prevents further damage, and that the body can adapt in remarkable ways. The goal is not perfection. The goal is the best recovery possible, and that goal is worth working toward, even if the recovery is incomplete.

Finally, I would say this to anyone who has never used nitrous oxide: do not start because it looks harmless. The high lasts a minute, and the damage can last months or years. That is a terrible exchange, and it is one that no one would accept if they saw it written down in advance. If someone offers you a balloon at a party, remember the tingling feet, the unsteady walk, the nights of broken sleep. Remember that the people who are living with that damage once thought it was harmless too. Walking away from the first balloon is easy. Walking away after the damage is done is much harder. Choose the easy walk.

I think about the families in this story a great deal, because they are the ones who notice the change first and feel most helpless about it. A parent watches their child stumble. A partner watches the person they love become unsteady and tired. They want to help, and they do not know how, and their worry can come out as nagging or as silence, neither of which helps. I think the most useful thing a family can do is simple and hard at the same time: to believe the symptoms, to go with the person to the appointment, and to be patient with a recovery that does not follow a timetable. That patience is a form of care, and it is often the care that matters most.

Work is another part of life that nitrous oxide touches quietly, and I think it deserves a mention. A person who cannot walk steadily, cannot concentrate, or cannot stay awake through a shift is a person whose job is at risk, and losing a job adds financial worry to an already difficult recovery. I would not advise anyone to hide the problem from their employer if safety is involved, especially in work that needs steady footing or quick reactions, but I understand why people are afraid to speak up. What I would say is that a job can be rebuilt, a shift pattern can change, and a short period of difficulty at work is a smaller price than permanent nerve damage. The body comes first, because without the body, there is no work at all.

There is a question I keep returning to, and it is this: why do we treat some substances as serious and others as a joke? Nitrous oxide is laughed about, it is passed around at parties, and it is spoken of as if it were harmless fun. Yet it can leave a young person unable to walk properly. That gap between the image and the reality is, in my view, the most dangerous thing about it. If the same damage came from a pill with a frightening name, people would take it seriously at once. Because it comes from a shiny canister and a balloon, they do not. I think we need to close that gap with plain information, given early and without embarrassment.

I also want to say something about hope, because this article has contained a lot of hard news, and I do not want to leave a reader with the feeling that nothing can be done. A great deal can be done. Stopping is the first and largest step, and it works from the first day. Medical care is the second, and it can identify exactly what has been damaged and what can be helped. Time is the third, and it is slow, but it is on the side of the person who has stopped. I have read enough about nerve recovery to know that improvement is real, that it continues for months, and that people who stopped early often regain a great deal of what they lost. That is not a promise. It is a reason to keep going.

When I think about the young people who use this gas, I think about how much of their lives is still ahead of them, and how much of that life depends on being able to walk, work, play sport, and dance without thinking about their feet. Those are not luxuries. They are the ordinary freedoms of a young body, and they are worth protecting. A minute of laughter is not worth a year of unsteadiness. I know that sounds like a lecture, and I do not mean it as one. I mean it as a simple calculation, made with the benefit of knowing what the damage looks like on the other side. If you are young and you have not yet felt the tingling, you are in the fortunate position of being able to choose. Choose the walk, the run, the dance. Choose the body you will need for the next fifty years.

I want to end this part by returning to the idea of patience, because it is the quality that recovery asks for most and rewards least visibly. Patience is not doing nothing. It is showing up for the appointment, eating the meal, taking the walk, and going to bed at a regular hour, even when none of those things feels as if it is changing anything. It is trusting that the body is working in the background, even when the evidence is invisible. That trust is hard to hold on a bad day, and it is easier to hold when someone else holds it with you, a friend, a family member, a clinician. If you can find one person to walk beside you through the slow months, the walk becomes bearable, and the destination becomes believable.

One last thing I would say to a person who has stopped and is waiting for the tingling to fade: keep your appointments, even when you feel nothing is changing. A clinician who sees you regularly can spot a problem early, can adjust the plan, and can tell you honestly whether the slow pace you are experiencing is normal. That reassurance is not a luxury. It is part of the treatment, because worry itself makes sleep worse, mood worse, and recovery harder. You do not need to carry this alone, and you do not need to guess. The help exists, and using it is the sensible, strong thing to do.

Frequently Asked Questions

What are the main side effects of nitrous oxide on the body after stopping?

After stopping, the most common problems are linked to nerve damage from low vitamin B12: tingling or numbness in the hands and feet, weakness in the legs, poor balance, and tiredness from anaemia. Sleep problems, low mood, irritability and anxiety are also common in the first weeks. Some of these improve over months, while nerve symptoms heal much more slowly. The exact picture varies from person to person, and it depends on how much and how long they used.

How quickly can nitrous oxide affect stop?

Some effects change quickly once use stops. The gas leaves the body fast, so the dizziness and confusion after each use fade within a day or two, and the risk of fainting or accidents while intoxicated ends at once. Other effects are slow: nerve damage can take weeks to show its full extent, and recovery of feeling, strength and balance is measured in months. Mood and sleep often begin to settle over the first few weeks, but they rarely return to normal overnight.

Can the harm nitrous oxide causes to the body after stopping be reversed?

Some of it can. Sleep, mood and thinking often improve over weeks and months, and mild nerve symptoms frequently ease, especially when use stops early and medical care is received. More serious nerve damage heals slowly and may leave some lasting numbness, weakness or balance trouble. Stopping completely is essential, because further use adds to the damage and slows recovery. A health professional can assess the damage and arrange follow-up.

Why does nitrous oxide affect the body after stopping?

Nitrous oxide switches off the active form of vitamin B12, which the nerves need to keep their protective coating healthy. Repeated use drains B12 stores and starves the nerves, especially the long nerves in the legs and the spinal cord. It also lowers red blood cell production, so the blood carries less oxygen. When use stops, the body has to rebuild B12 levels and repair damaged nerves, and that repair is slow, which is why symptoms can linger long after the gas is gone.

When should someone seek help about nitrous oxide and the body after stopping?

Help should be sought promptly if there is tingling or numbness that does not fade, weakness in the legs, trouble with balance, bladder or bowel changes, severe tiredness, or low mood that does not lift. A health professional can check B12 levels, test nerve function, and arrange treatment and follow-up. Urgent care is needed for severe confusion, fits, severe weakness, or trouble breathing. Anyone who finds it hard to stop using should also ask for support.

Where can I learn more about nitrous oxide and stopping use?

Good places to read about nitrous oxide and stopping use are the NHS, the National Institute on Drug Abuse, and the Mayo Clinic, linked in the Sources section. A health professional can also talk through worries about nitrous oxide and stopping use.
