What Does Marijuana Do to Your Brain

Marijuana is often talked about as if it only relaxes people, yet its main effects happen in the brain, and many of them are not relaxing at all once you look closely. The plant contains a chemical called THC, which is the part that changes how a person feels, thinks and reacts. When THC reaches the brain, it interferes with the normal signals that brain cells send to each other. That interference is why thinking can feel slower, memories can feel harder to hold on to, and ordinary decisions can take more effort than usual. The change may feel mild on a single occasion, especially if the amount was small, but the effect is real, and it becomes clearer when use is repeated over weeks, months and years.

This article explains, in plain words, what marijuana does to the brain: what happens shortly after use, how memory and learning are affected, why attention and judgement suffer, how mood and sleep are involved, and what may improve after a person stops. It is general information, not individual medical advice. If you are worried about your own thinking, memory or mood, or about someone close to you, a qualified health professional is the right person to talk to.

What Happens in the Brain Shortly After Use

When a person smokes marijuana, THC travels from the lungs into the blood and reaches the brain within minutes. When it is eaten, the effect usually arrives more slowly, because the food must first be digested, but the effect can then last longer and feel stronger than expected. Either way, THC acts on parts of the brain that help control memory, attention, movement, pleasure and the sense of time. It binds to docking points on brain cells that normally respond to the brain’s own natural chemicals. Those natural chemicals help the brain pass messages in an orderly way. THC pushes the system harder and less evenly, so messages arrive out of order or with the wrong strength.

That is why a person may feel that time is moving slowly, that a simple thought has slipped away, or that a conversation is hard to follow. A name that was known a moment ago can suddenly feel out of reach. A sentence that started clearly can lose its ending halfway through. The person may laugh at something that is not funny, or feel unusually hungry, or feel that sounds and colours are stronger than usual. These changes can feel pleasant at first, which is one reason people return to the drug, but they are signs that normal brain signalling has been disturbed, not signs that the brain is working better.

Reaction time also slows. A person who has used marijuana may take longer to notice a change on the road, to respond to a question, or to catch a mistake before it happens. Coordination can become clumsy, balance can feel less steady, and tasks that need two things at once, such as listening while writing, become harder. For most people these short-term effects fade over several hours, yet the length of time depends on the amount used, the strength of the product, and whether the person has eaten, slept or used other substances. Stronger products available today can produce a much heavier effect than weaker products from many years ago, and eating a large amount by mistake can leave a person feeling confused and unwell for a long time.

How Thinking, Memory and Learning Change

Memory is one of the parts of thinking most clearly affected by marijuana. The brain forms new memories in an area called the hippocampus, and that area is rich in the docking points that THC acts on. When THC is present, the hippocampus finds it harder to record new information properly. A person may read a page and then realise almost nothing has stayed in mind. They may be told an instruction and forget it before they have had a chance to act on it. They may meet someone new and forget the name within minutes. Older memories, formed before use, are usually less affected, which can make the problem confusing. A person can still remember childhood events clearly while struggling to remember what happened yesterday.

Learning new skills becomes slower for the same reason. Learning depends on paying attention, holding information in mind, and then storing it. Marijuana weakens each of those steps. A student may need to read the same lesson several times. A worker learning a new machine may need more demonstrations than before. A person learning a language may find new words slipping away, even after careful study. None of this means the person has become unintelligent. It means the brain’s recording system is working under interference, and the interference grows with frequent use.

Over time, people who use marijuana often also find it harder to organise their thoughts. Planning a day, breaking a large task into small steps, or keeping track of several things at once can feel unusually tiring. This kind of thinking, sometimes called executive function, depends on the front part of the brain, which helps a person weigh choices, resist impulses and stay on track. When that part is affected, a person may start tasks and leave them unfinished, lose track of what they were doing, or make choices without thinking through the consequences. Family members often notice this before the person does, because they see the unfinished work, the missed appointments and the plans that never quite happen.

Attention, Focus and Everyday Mistakes

Attention is not one single skill. It includes staying focused on a task, switching between tasks when needed, and ignoring distractions. Marijuana can weaken all three. A person may sit down to work and find their mind wandering within minutes. They may start reading an email, then check their phone, then forget the email entirely. They may listen to a friend and realise they have missed the middle of the story. These slips are common in everyone from time to time, but with regular marijuana use they happen more often, and they take more effort to correct.

The problem is easy to miss because it grows slowly. A person adjusts to the new normal without noticing the change. They may blame tiredness, stress or a busy life, and those things can certainly play a part. Yet when the pattern keeps returning, and when it is worse on days after use, the drug is a likely contributor. Small mistakes begin to cost more: a wrong number entered at work, a message sent to the wrong person, a pot left on the stove, a door left unlocked. None of these mistakes on its own proves serious harm, but together they show a brain that is working harder for results that used to come easily.

Sustained attention, the ability to keep going on a dull but necessary task, is often hit hardest. Many jobs and many courses depend on it. A person may be able to focus for a short burst, especially on something interesting, but struggle to stay with a long, ordinary task. They may feel mentally tired earlier in the day, even after a full night’s sleep. That tiredness is not laziness. It is the result of a brain that must spend extra energy to do basic work, and that extra energy runs out sooner. Over weeks, the person may begin to avoid difficult tasks altogether, not because they do not care, but because the tasks feel heavier than they should.

Mood, Anxiety and Sleep

Marijuana is often used to relax, yet its effect on mood is complicated and often goes in the opposite direction over time. In the short term, some people feel calmer, happier or less worried. Others feel anxious, nervous or suspicious, especially after a large amount or a strong product. A racing heart, a dry mouth and a feeling that something is wrong can turn a pleasant evening into a frightening one. These reactions are more common in people who are new to the drug, who have taken more than they intended, or who already live with anxiety.

With regular use, mood can become less stable. A person may feel flat and unmotivated between uses, then briefly better after using, then flat again. That cycle can look like relief, but it is really the brain swinging between the drug’s effect and its absence. Over months, some regular users report feeling less interested in things they once enjoyed, less eager to meet friends, and less driven to work towards goals. This loss of drive is sometimes called amotivation, and it is one of the most quietly damaging effects, because it does not feel like an illness. It feels like a personality change, and the person may not connect it with the drug at all.

Sleep is affected too. Marijuana can make a person feel sleepy and help them fall asleep more quickly, which is why some people use it at night. But the sleep it produces is often lighter and less refreshing. Dreams may become less vivid or disappear, and waking up may still leave the person feeling tired. When use stops after a long period, sleep often becomes disturbed for a while, with vivid dreams, restless nights and difficulty falling asleep. That disturbance is temporary for most people, but it can be strong enough to push them back to using, simply to get a quiet night. Understanding that this is a withdrawal effect, not proof that the drug is needed for sleep, can make it easier to get through.

How the Brain Changes Over Months and Years

The brain is not a fixed machine. It changes in response to what it experiences, and repeated marijuana use teaches it to expect THC. Over time, the brain reduces the number or sensitivity of the docking points that THC acts on, as a way of coping with the constant stimulation. That adaptation is called tolerance. It means the same amount produces a weaker effect, so a person may use more, or use a stronger product, to feel the same as before. Tolerance is not a sign that the drug has become safe. It is a sign that the brain has changed its normal balance to accommodate the drug.

Research that follows large groups of people over many years has found that heavy, long-term use is linked with poorer performance on tests of memory, attention and planning, even when people are not under the influence at the time of testing. The size of the effect varies. Some people show only small differences, while others show larger ones, especially if they started young or used heavily for many years. The findings do not prove that marijuana alone causes every difference, because life is complicated and many factors affect thinking, but the pattern appears again and again in different countries and different groups, and it is strongest for the heaviest users.

There is also evidence linking heavy, long-term use with a higher risk of mental health problems, including anxiety, depression and, in a smaller number of people, psychosis, which is a serious condition in which a person loses touch with reality. The risk is higher for people who start young, use strong products often, or already have a family history of mental illness. This does not mean that every user will develop such a problem. Most do not. It does mean that the risk is real and worth taking seriously, especially for teenagers and young adults, and especially when use is heavy and daily.

Young Brains and Why Age Matters

The brain keeps developing well into the mid-twenties, and the parts that handle planning, self-control and weighing consequences are among the last to mature. That is why starting marijuana use in the teenage years carries more risk than starting as an adult. A young brain is still building its connections, and regular THC exposure during that period can interfere with how those connections form. Studies of teenagers who use marijuana heavily have found weaker memory and attention than in teenagers who do not use it, and the differences can still be seen after periods without use.

School performance is often the first place the damage shows. Grades may fall, homework may be left unfinished, and interest in lessons may fade. A teenager may still be bright and capable, but the daily work of learning becomes harder, and the gap between ability and results grows. Teachers and parents may think the teenager has simply lost interest, when in fact the brain is struggling to record and organise new information. Because adolescence is also a time when friendships, confidence and future plans are forming, a loss of drive at this age can shape the years that follow in ways that are hard to undo.

Young people are also more likely to take risks, and marijuana can make that tendency stronger. When judgement is weakened, a teenager may agree to things they would normally refuse, drive after using, or use other substances alongside marijuana. The combination can be dangerous, because each substance adds its own impairment. None of this is about blaming young people. It is about recognising that a developing brain is more sensitive to interference, and that early, heavy use carries a cost that may not be obvious until much later.

Driving, Work and Decisions

Judgement is the quiet skill behind almost every important choice, and marijuana weakens it in ways that are easy to underestimate. After use, a person may feel confident that they are fine to drive, to operate a machine, or to make a big decision, when in fact their reactions are slower and their thinking is less sharp. That false confidence is part of the danger. Alcohol often makes people feel unsteady, which at least warns them that something is wrong. Marijuana can leave a person feeling calm and capable while their performance has clearly dropped.

Driving after marijuana use is a serious risk. Studies have found that drivers who have recently used marijuana are more likely to be involved in crashes, because they react more slowly, drift out of lane, and misjudge distances and speeds. The risk rises further when marijuana is combined with alcohol, even in small amounts. Laws differ from place to place, but the safety point does not change: a person who has used marijuana should not drive until the effects have fully worn off, and for strong products or eaten products that can take many hours, or even until the next day.

At work, the effects show up as slower work, more errors, and difficulty following instructions that have several steps. A person may be able to do familiar, simple tasks, but struggle when something unexpected happens and a quick, clear decision is needed. In jobs that involve safety, such as driving, construction, operating machinery or caring for others, that loss of sharpness can put the worker and other people at risk. Even in office work, the cost appears over time: missed deadlines, forgotten meetings, and a reputation for unreliability that the person may not understand, because from inside, the effort feels the same as before.

What Happens When Use Stops

Stopping marijuana is not the same as stopping a drug that causes severe physical withdrawal, yet many regular users do feel withdrawal, and it can be uncomfortable enough to make quitting hard. The most common symptoms are irritability, restlessness, low mood, poor sleep, vivid dreams, reduced appetite and cravings. These usually begin within a day or two of stopping, peak in the first week, and fade over two to four weeks. For people who have used heavily for years, the disturbed sleep and low mood can last longer, but they do usually improve with time.

Thinking also recovers, but slowly. In the first days after stopping, memory and attention may feel worse, not better, because the brain is adjusting to the absence of THC. That early dip can be discouraging, and it leads some people to conclude that quitting has made them worse. In fact, the brain is relearning how to work without the drug, and that process takes time. Over weeks and months, most people who stop notice that their thinking becomes clearer, their memory improves, and they can concentrate for longer. The speed of recovery depends on how long and how heavily the person used, and on their age when they started. People who used for a shorter time, or who started as adults, tend to recover more fully and more quickly.

Not all effects may fully reverse after very heavy, long-term use that began in adolescence, and researchers are still studying how complete recovery can be in those cases. That uncertainty is not a reason to give up on stopping. Every month without use is a month in which the brain is no longer under daily interference, and the risk of further harm stops growing. Support can help a great deal: talking to a health professional, telling family or friends, finding other ways to relax and sleep, and planning for the moments when cravings are strongest. Quitting is easier with a plan than with willpower alone, and asking for help is a sign of good judgement, not weakness.

Marijuana, Stress and Coping

Many people turn to marijuana because life feels heavy. Work pressure, money worries, family arguments, loneliness and poor sleep can all make a person reach for something that promises quick relief. In the moment, marijuana can seem to deliver that relief. The tension eases, the worries feel further away, and the evening passes more easily. The trouble is that the relief does not solve the problem that caused the stress. The work is still there in the morning, the money worry is still there, and the argument is still unresolved. What has changed is that the person has had less practice in facing those problems clearly, because the drug offered an easier way out.

Over time, this pattern can become the main way a person copes. Instead of talking through a problem, taking a walk, getting proper rest or asking for help, they use marijuana first. Each time that happens, the brain learns that the drug is the answer to discomfort, and other coping skills grow weaker from lack of use. Stress then feels harder to bear without the drug, not because the stress has grown, but because the person has fewer tools to handle it. This is one reason regular use can be so hard to break. It is not only a habit of the body. It is a habit of dealing with life, and breaking it means learning new ways to cope, which takes time and support.

There is also a social side to this. In some groups, using marijuana is normal, expected, even a sign of belonging. A person who wants to stop may find that most of their social life revolves around use, and that saying no means spending less time with friends. That social pressure is real, and it should not be dismissed as weakness. Changing a habit often means changing routines and sometimes changing company, at least for a while, and that is a genuine loss. Yet it is also true that friends who care about a person will usually respect an honest decision to stop, especially when the reasons are explained clearly. Finding new routines, new interests and people who do not centre their social life on the drug can make stopping far more sustainable than trying to resist in the same setting every day.

It is worth remembering, too, that marijuana is sometimes presented as a natural remedy for stress, anxiety or pain, as if being natural made it safe. Many natural things are harmful in large amounts, and the word natural tells us nothing about safety. The question is not whether the plant grows in the ground. The question is what its active chemical does to the brain when it is used repeatedly, and the evidence on that point is clear enough: it interferes with memory, attention, judgement and mood, and it can make the very problems it is used to escape harder to solve in the long run. A person who wants help with stress, anxiety or pain deserves proper support for those problems, not a drug that dulls the brain while the problems remain.

My Take:

I want to be clear about where I stand on marijuana, because this is a topic where people often hear only one side. I do not think people who use marijuana are bad people, and I do not think the answer is to judge them or to lecture them. Many people start because their friends use it, because they are curious, because they want to relax after a hard day, or because they are struggling with stress, low mood or poor sleep and someone told them it would help. Those are human reasons, and they deserve understanding, not scorn. At the same time, I think the idea that marijuana is harmless is simply wrong, and I think it does real damage to the brain, especially when it is used often, in strong forms, and from a young age.

The part that worries me most is how quiet the damage is. If a drug caused a broken bone, everyone would see it and take it seriously. Marijuana does something slower and harder to see. It makes memory a little weaker, attention a little shorter, and decisions a little hastier, month after month, until the person has adjusted to a lower level of sharpness and forgotten what clear thinking felt like. I find that frightening, because by the time the change is obvious, years have passed, and some of those years were the years that mattered most for learning, for work and for building a future. A student who loses two years of good learning does not get those years back easily. A worker who gains a reputation for unreliability does not lose it overnight.

I also think the memory problem is the part that people underestimate most. We treat memory as if it were only about remembering names and dates, but memory is really about learning, about work, about relationships and about daily life. When you cannot remember what you were told this morning, you cannot do your job properly. When you cannot remember a conversation with your partner, the relationship suffers. When you cannot remember what you studied last night, the exam suffers. These are not small things. They are the threads that hold a normal day together, and marijuana loosens them one by one. I have seen how frustrating that can be for the people around a user, who watch someone they care about become more forgetful and less reliable, and who do not know how to raise the subject without starting an argument.

The false confidence after use is another thing I think about a lot. A person who has used marijuana often feels calm, even capable, and that feeling is dangerously misleading. They feel fine to drive, fine to make a decision, fine to handle a machine, when a simple test would show that their reactions are slower and their judgement is weaker. That gap between feeling and reality is where accidents happen. I would rather a person felt unsteady and knew they were impaired than felt calm and believed they were fine. The calm is not proof of safety. It is part of the drug’s effect, and it hides the impairment from the very person who needs to see it.

Young people are the group I worry about most, and I will say why plainly. A teenager’s brain is still being built, and the choices made at sixteen or seventeen can shape the next ten years. If a teenager spends those years using marijuana heavily, they are not just risking a bad grade. They are risking the habits, the learning and the confidence that carry them into adult life. I know teenagers do not like being told this, and I know many adults who used marijuana as teenagers and turned out fine will say it did them no harm. That may be true for them, and I am glad for it. But the research is clear that the risk is higher for young users, and that some young users do suffer lasting harm. A risk that only affects some people is still a real risk, and it is not fair to pretend otherwise.

I think the loss of drive is the saddest effect of all, because it looks like a personality change and it is so easy to misread. A person who once had plans, energy and curiosity slowly becomes content to do very little, to stay in, to put things off until tomorrow. Friends drift away, opportunities pass, and the person tells themselves they are simply relaxed, when in fact the drug has dulled the very drive that pushes a person forward. I do not say this to be cruel. I say it because I have seen how much a person can lose without noticing, and how much better they can feel when that drive starts to return after they stop. The return of energy and interest is often the first thing people notice when they quit, and it is a powerful reminder of what was lost.

I am also honest about the fact that quitting is not easy, and I do not want to pretend that it is. The first week can be irritable and sleepless, with vivid dreams and a constant urge to use again. The second week can feel flat, as if nothing is enjoyable without the drug. That flatness is not the real you. It is the brain readjusting, and it passes. By the third or fourth week, most people who stop say their thinking is clearer, their sleep is deeper, and their mood is steadier. I think it helps to know that in advance, because the hardest days are also the days when a person is most likely to give up, and knowing that the discomfort is temporary can make the difference between quitting and going back.

If you use marijuana and you are reading this, I would ask you to do one honest thing: notice the pattern for yourself. Do not take my word for it, and do not take anyone else’s word for it. Keep a simple note for two weeks, of how often you use, how well you sleep, how clearly you think, and how much you get done. Then stop for two weeks, if you can, and keep the same note. Compare the two. I think many people would be surprised by the difference, and I think that difference, seen in their own life, is more convincing than any article. If stopping feels very hard, that itself is useful information. It tells you that the drug has a stronger hold than you thought, and that is a reason to seek support, not a reason to feel ashamed.

I would also say this to parents and partners. If someone you love uses marijuana heavily and you have noticed their memory, their mood or their drive changing, do not start with a lecture. Start with what you have seen, calmly and specifically. Tell them you have noticed they forget things more often, or that they seem less interested in the things they used to enjoy, and that you are worried about them. Ask them how they feel, and listen to the answer. People are more likely to change when they feel understood than when they feel judged, and a conversation that begins with care has a better chance than one that begins with blame. If the conversation is difficult, a health professional can help, and family support services exist in many places for exactly this reason.

Finally, I want to say something to anyone who has never used marijuana and is thinking about trying it. The first experience may feel pleasant, even harmless, and that is part of the trap. The harm does not arrive all at once. It arrives slowly, in small losses of memory, focus and drive that are easy to dismiss. By the time the losses are obvious, the habit is already established, and stopping is harder than starting ever was. The easiest way to avoid that trap is not to step into it. There are better ways to relax, to sleep and to cope with stress, and they do not cost you your sharpness. If you are already using, the best time to stop was earlier, and the second-best time is now. Your brain is remarkably able to recover, and every day without the drug gives it a better chance to do so.

I think the confusion about the law makes all of this harder. In some places marijuana is legal, in others it is not, and in many places the rules are changing or unclear. People often hear that it is legal somewhere and conclude that it must be safe everywhere. That is a mistake. The law is about politics, tax, policing and public opinion, not about what a chemical does inside the brain. Alcohol is legal in most countries, and no one who has seen its damage would call it harmless. Tobacco is legal, and its harm is beyond doubt. Legality tells you what the state allows. It does not tell you what is good for your memory, your judgement or your future. I wish more public discussion made that distinction clearly, because I think many people, especially young people, are being misled by it.

Social pressure is another part of the story that deserves honesty. Many people do not start using marijuana alone. They start because friends are using it, because refusing feels awkward, or because they want to fit in. I understand that pressure, and I do not blame anyone for feeling it. But I would say this: the friends who matter will not think less of you for saying no, and the habit you pick up to please other people is a habit you will carry alone when the evening is over. Learning to say no calmly, without a lecture and without an apology, is a skill worth having, and it protects you in far more situations than this one. If your whole social circle depends on using together, that itself is worth thinking about, because a friendship that only works with a drug in the middle is a fragile friendship.

Money is a practical point that people often ignore until they add it up. Regular marijuana use costs money every week, and over a year that money becomes a large sum. It is money that could have gone towards savings, a course, a holiday, or help for the family. I am not saying money is the most important reason to stop, because health matters more, but money is concrete, and it can be a powerful motivator. A person who stops often notices the difference in their pocket within weeks, and that visible saving is a weekly reminder that the decision is working. It is a small reward, but it arrives regularly, and regular rewards help a person stay on track.

I also want to address the comparison with alcohol, because it comes up in almost every discussion about marijuana. People say alcohol is worse, so marijuana must be fine. That argument does not work. The fact that one thing is harmful does not make another thing safe. Alcohol damages the liver, the brain and relationships, and its harm is well known. Marijuana damages memory, attention, judgement and mood in its own way. Both can ruin a life, and both deserve to be taken seriously. I do not think we should measure drugs against each other and excuse the less harmful one. We should measure each drug against a clear mind and a healthy life, and ask whether it helps or harms. On that measure, regular marijuana use fails, whatever alcohol does.

Finally, I want to end on hope, because this article has been heavy, and hope is honest too. The brain can recover, and people do recover. I have seen people who used heavily for years stop, struggle through the first hard weeks, and then slowly become sharper, more interested in life, and more reliable at work and at home. It does not happen overnight, and it does not happen without effort, but it happens. The first month is the hardest, the second month is easier, and by the third month many people say they feel like themselves again, only clearer. If you are in the middle of that struggle, do not judge the whole journey by the hardest week. Keep going, ask for help when you need it, and give your brain the time it needs to heal. It is worth the effort, and you are worth the effort.

Asking for help is the last point I want to make, because it is the one people resist most. Many people try to quit alone, in silence, because they feel embarrassed or because they think they should be able to manage on their own. I understand that feeling, but I think it makes quitting far harder than it needs to be. Talking to a doctor, telling a trusted friend, or joining a support service does not mean you are weak. It means you are serious about changing, and you are giving yourself the best chance to succeed. The first weeks are the hardest, and they are much easier to get through when someone else knows what you are doing and can encourage you when the cravings are strong. If you have tried before and gone back, that does not mean you have failed. It means you have learned something about what triggers you, and the next attempt can be stronger because of it.

Frequently Asked Questions

How does marijuana affect attention?

Marijuana weakens attention by interfering with the brain signals that help a person stay focused, switch between tasks and ignore distractions. Shortly after use, focus becomes shorter and the mind wanders more easily. With regular use, the problem can persist even between uses, so ordinary tasks need more effort and mistakes become more common. The effect is strongest for long, dull tasks that need sustained concentration, and it tends to ease gradually over weeks after a person stops.

Can marijuana cause mental tiredness even in light users?

Yes, it can, although the risk is lower than for heavy daily users. Even a few uses a week create repeated interference with memory and attention, and the brain must work harder to do ordinary thinking, which leaves a person feeling mentally tired earlier in the day. Light users may also sleep less deeply after use, which adds to the tiredness. Less use means less strain, but the clearest way to remove the strain is to stop altogether.

How long does it take for marijuana to harm attention?

There is no single timetable, because the strength of the product, the amount used, the person’s age and how often they use it all matter. Some people notice foggy thinking and poor focus within weeks of regular use, while for others the change builds slowly over months or years. The direction matters more than the exact date: the longer and heavier the use, the more likely attention is to suffer. Early signs, such as forgetting instructions or losing track in conversations, are worth noticing before the harm grows.

Does stopping marijuana help reaction time recover?

In many cases yes, but recovery is gradual rather than instant. In the first week or two after stopping, thinking and reaction time can feel worse because of withdrawal and disturbed sleep. As those effects fade over the following weeks, most people notice clearer thinking, better memory and quicker reactions. The improvement is usually greater for people who used for a shorter time or started as adults, and it is helped by regular sleep, exercise and keeping the mind active.

Why do people keep using marijuana if it harms thinking?

People keep using it for several reasons that work together. The drug can feel relaxing in the moment, it becomes part of daily routine and social life, and it may be used to cope with stress, low mood or poor sleep. The harm to thinking arrives slowly, so it does not feel like an immediate warning, and the person may blame tiredness or stress instead. When the brain adapts to regular use, stopping can feel uncomfortable, which makes the habit harder to break without support and a clear plan.

When should someone seek advice about marijuana and judgement?

It is sensible to seek advice when poor memory, slow reactions or weak judgement keep returning, when they interfere with work, study, driving or family life, or when stopping feels very hard. A health professional can give general information, check for other causes, and explain the support options available. Help should be sought urgently if a person becomes severely confused, very anxious or suspicious, or loses touch with reality after use.
