How Does Khat Change Your Mood
In this post
Mood is one of the things khat changes most, and one of the things people talk about least honestly. In the first hours, khat can make a person feel brighter, more talkative, and more confident. That lift is the reason many people use it, and it is a real feeling, not an imagined one. But the lift is short, and what follows it is often longer and heavier: a flat, low mood, irritability, worry, and a feeling that ordinary pleasures have lost their colour. Over weeks and months of regular use, the balance shifts. The good hours get shorter, the low hours get longer, and the person’s normal mood, the mood they have on an ordinary day without khat, starts to sink.
This matters because mood is not a small side issue. It shapes how a person treats their family, how they work, how they sleep, and how they see their own life. A person whose mood is constantly swinging up and down finds it hard to plan, hard to keep promises, and hard to trust their own feelings. The people around them find it hard too, because they never quite know which version of the person will walk through the door. This article explains, in plain words, how khat changes mood: the lift, the crash that follows, the anxiety and irritability that creep in, the flatness that builds over time, and what can help mood recover. It is general information, not individual medical advice. If low mood or anxiety is affecting your life, a qualified health professional is the right person to talk to.
What Khat Does to Mood in the First Hours
Khat contains a natural stimulant, and stimulants work on the brain’s reward and alertness systems. When the active substances reach the brain, they increase the activity of chemicals linked with energy, focus, and pleasure. The person feels more awake, more interested in conversation, and more confident. In a social gathering, that can feel wonderful. A quiet person becomes talkative. A tired person feels energetic. Worries that felt heavy an hour ago feel lighter, or seem to disappear altogether. For a few hours, the world feels brighter and easier.
It is important to understand that this lift is borrowed, not earned. The brain has not solved any of the problems that were causing worry. It has simply been pushed into a state where it notices them less. The money worries, the work stress, and the family tensions are all still there, waiting. The stimulant has turned the volume down on them for a while, but it has not changed them. When the effect wears off, the volume comes back, often louder than before, because the brain is now tired as well as worried.
The lift also depends on the setting. In a friendly gathering, with people laughing and talking, the mood lift feels social and warm. Alone, the same stimulation can feel restless and edgy, with the mind racing but nowhere to go. Some people find that they become more talkative but also more repetitive, going over the same points again and again. Others find that they feel confident in the moment but later feel embarrassed about things they said or promised while they were under the influence. That gap between how a person feels during the lift and how they feel about it afterwards is one of the first signs that the mood change is not as simple as it seemed.
There is another point that is easy to miss. The lift is strongest when use is occasional. When use becomes regular, the brain adapts. It gets used to the extra stimulation, and the same amount of khat produces a smaller lift. A person may find they need to use more, or use for longer, to feel the way they used to feel at the start. This is tolerance, and it is a normal response of the brain to a repeated stimulant. It means the good feeling gets harder to reach, while the low feeling afterwards stays just as strong, or gets stronger. That is a bad trade, and it is one of the reasons regular use tends to make mood worse overall, even though each session starts with a lift.
The Crash After the Lift
Every stimulant lift has a crash, and with khat the crash is often the longest part of the experience. As the active substances wear off, the brain’s alertness drops, and the chemicals that were pushed up fall back down, sometimes below their normal level. The person feels the opposite of the lift: tired, flat, heavy, and low. Energy disappears. The talkativeness fades, and is replaced by silence or irritability. Things that felt interesting an hour ago now feel dull. Food may lose its taste. The desire to do anything, even simple things, drains away.
The crash is not just tiredness. It is a mood change. Many people describe feeling sad, empty, or hopeless in the hours after khat wears off, even when nothing bad has happened. That is because the brain’s reward system has been pushed hard and is now running low. Ordinary pleasures, a meal, a conversation, a walk, do not feel rewarding in that state, because the brain is comparing them with the artificial high of a few hours ago, and they cannot compete. This is why the crash feels so unfair. The person did nothing wrong, and yet they feel low, and they do not know why, or they blame themselves for feeling low, which makes it worse.
Sleep makes the crash worse. Khat often keeps a person up late, so the crash arrives on top of a night of broken sleep. A tired brain is a low brain, and a low brain finds it harder to cope with the crash. The next day, the person wakes up feeling flat and exhausted, and the temptation is to use khat again to lift the mood back up. That works, for a few hours, but it sets up the next crash, which will be just as deep, or deeper. This is the cycle that traps many regular users: lift, crash, lift, crash, with the crashes slowly taking up more of the week than the lifts.
It is worth saying that the crash is not a sign of weakness. It is a normal chemical response, and it happens to almost everyone who uses a stimulant regularly. Knowing that can help, because it means the low feeling is not proof that life is hopeless, or that the person is a bad person. It is proof that the brain is reacting to a substance, and that the substance is the problem, not the person. That distinction matters, because blame makes people hide their problems, while understanding makes them more likely to ask for help.
Anxiety Moves In
Anxiety is one of the most common mood effects of regular khat use, and it often arrives quietly. At first, it may show up only in the hours after use, when the mind is still racing but the energy has gone. A person may feel on edge, worried about things that would not normally bother them, or unable to relax even when they are safe at home. Their heart may beat faster, their hands may feel restless, and their thoughts may keep circling around the same worries. That feeling can last for hours, and it can make the evening feel tense and unhappy, instead of restful.
Over time, the anxiety can spread beyond the hours after use. A person may start to feel anxious during the day, even when they have not used khat that day. They may worry more about money, work, or their health. They may find it hard to sit still, hard to concentrate, and hard to enjoy a quiet moment. Social situations that used to be easy can start to feel stressful. A person may worry about what others think of them, or about saying the wrong thing, in a way they never did before. That is not a personality change. It is what happens when the brain’s alertness system has been pushed too hard, too often, and has become stuck in a state of high alert.
There is a close link between anxiety and sleep here. Poor sleep makes anxiety worse, and anxiety makes sleep worse. A person who lies awake worrying will sleep badly, and a person who sleeps badly will worry more the next day. Khat feeds both sides of that circle, by disturbing sleep and by raising anxiety directly. Breaking the circle usually means addressing both, and the first step is often the hardest one: recognising that the anxiety is linked with the khat, not just with life in general. Life has real worries, and khat does not create all of them. But it makes the brain less able to cope with them, and that is a real and important effect.
It is also important to be honest about the fact that some people use khat because they already feel anxious, and they hope it will help them relax or feel more confident in social situations. In the short term, it can feel that way, especially in a friendly gathering. But in the longer term, it tends to make anxiety worse, not better, because the crash and the sleep loss add new anxiety on top of the old. A person who started using khat to cope with worry may end up with more worry than they started with, and with a habit that is hard to stop. If anxiety is a problem, talking to a health professional about it is a better path than relying on a stimulant that makes the underlying problem worse.
Irritability and Short Temper
Irritability is a mood change that other people notice before the person does. A person who uses khat regularly may become quicker to snap, less patient with small frustrations, and more likely to raise their voice over things that would not have bothered them before. A child asking a question twice, a queue moving slowly, a colleague making a small mistake, these ordinary moments can suddenly feel unbearable. The person may feel a flash of anger that seems out of proportion, and afterwards they may feel ashamed or confused about why they reacted that way.
There are several reasons for this. The first is tiredness. Poor sleep makes everyone more irritable, and khat regularly steals sleep. The second is the crash. When the brain is coming down from a stimulant, it is low on the chemicals that help with patience and self-control, so small frustrations feel bigger. The third is the stimulant itself. While it is active, it can make a person feel restless and on edge, and that edginess can turn into impatience with anyone who interrupts or slows them down. Put together, these three effects make a short temper much more likely, and they make it harder for the person to stop and think before they react.
The consequences of irritability are often felt at home. A partner may start to avoid bringing up problems, because they do not know how the person will react. Children may become quieter, or more anxious, around a parent whose mood changes suddenly. Friends may stop inviting the person to things, or may keep conversations short. None of this is because the family or friends do not care. It is because living with unpredictable anger is exhausting, and people protect themselves by pulling back. That pulling back can then make the person feel lonely or rejected, which makes their mood worse, and the circle continues.
It helps to name this plainly, because many people blame themselves for being a bad-tempered person, when the real cause is a substance that is changing their mood. That does not excuse hurtful behaviour, and it does not mean the family should accept it. But it does mean the problem has a cause that can be addressed, rather than being a fixed part of who the person is. If irritability is becoming a pattern, and if it is harming relationships at home, that is a strong reason to talk to a health professional and to think seriously about stopping. The people at home deserve a calm version of the person they love, and the person themselves deserves to feel calm too.
Feeling Flat and Empty Over Time
One of the saddest long-term effects of regular khat use is flatness: a feeling that life has lost its colour. This does not arrive all at once. It builds slowly, as the brain gets used to the artificial lift of the stimulant and starts to respond less to ordinary pleasures. A meal that used to be enjoyable tastes plain. A joke that used to make a person laugh barely raises a smile. A walk, a game, a conversation with a friend, all of them feel like effort, with little reward at the end. The person may still go through the motions of daily life, but the feeling behind those motions has gone quiet.
This flatness is linked with how the brain’s reward system works. When a stimulant pushes that system hard, again and again, the system becomes less sensitive. It needs a stronger push to feel the same pleasure, and ordinary life cannot provide that push. The result is that the person feels flat most of the time, and only feels normal, or good, during the brief lift of khat use. Over time, that can make khat feel necessary, not because the person loves the lift, but because it is the only time they feel anything at all. That is a difficult and lonely place to be, and it is one of the clearest signs that regular use has changed the brain’s mood system.
Flatness is different from ordinary sadness, although the two often appear together. Sadness usually has a cause, a loss, a disappointment, a worry, and it comes in waves. Flatness is more like a fog that does not lift. The person may not feel actively sad, but they also do not feel happy, interested, or motivated. They may struggle to get out of bed, not because they are in pain, but because nothing feels worth getting up for. They may put off work, avoid friends, and let small tasks pile up, because starting anything feels like too much effort for too little reward. Family members may say the person has become distant or lazy, when the truth is that their brain is no longer giving them the normal signals of pleasure and motivation.
It is important to say that this flatness can improve. The brain is able to recover its sensitivity to ordinary pleasures, but it takes time, and it takes a period without the stimulant pushing it around. In the first weeks after stopping, the flatness may feel worse, because the brain is still waiting for the lift that no longer comes. But gradually, over weeks and months, ordinary things start to feel rewarding again. Food tastes better. A conversation feels warmer. A small achievement feels satisfying. That recovery is slow, and it is not always steady, but it is real, and it is one of the best reasons to stop. The goal is not just to avoid feeling bad. It is to feel good again, in the ordinary, everyday way that does not need a substance to work.
Mood Swings and Relationships
When mood swings up and down every day, relationships take the strain. A partner may feel as if they are living with two different people: one who is talkative, warm, and full of plans in the evening, and another who is flat, irritable, and withdrawn the next morning. That unpredictability makes it hard to plan anything together, hard to have an honest conversation, and hard to trust that a promise made in the evening will be kept in the morning. Over time, trust wears thin, not because of one big betrayal, but because of a hundred small disappointments, each one caused by a mood that changed without warning.
Children are affected in a particular way. A child does not understand stimulants or mood chemistry. They only see that a parent is sometimes warm and sometimes cold, sometimes patient and sometimes angry, and they cannot predict which one they will get. That unpredictability can make a child anxious, clingy, or withdrawn. They may try to be extra good to keep the parent happy, or they may stop trying altogether, because they have learned that their behaviour does not change the parent’s mood. Either way, the child is carrying a burden that is not theirs to carry, and the effects can last long after the childhood is over.
Friends and work colleagues feel the swings too. A person may be full of ideas and energy one day, and impossible to reach the next. They may agree to help with something and then fail to follow through, because their mood has crashed. They may cancel plans at the last minute, or turn up late and distracted. After a while, people stop relying on them, and they stop being invited to the things that matter. That loss of connection is painful, and it can make the person feel isolated, which makes their mood worse, and makes them more likely to turn back to khat for company or comfort. It is a circle that is easy to enter and hard to leave, and it starts with something as simple as a mood that will not stay steady.
The way out of that circle is not to blame the family or the friends for pulling away. They are protecting themselves, and that is understandable. The way out is to address the cause of the swings, and to be honest with the people who have been affected. That honesty is hard, but it is also the beginning of repair. A person who says, “My mood has been unstable, and I know it has hurt you, and I am working on it,” is giving their family something real to hold on to. It does not fix the past, but it changes the future, because it replaces unpredictability with a clear, honest effort to change.
When Low Mood Lingers
For some people, regular khat use is linked with a low mood that does not lift after the crash has passed. It becomes a steady, heavy feeling that lasts for days or weeks, even on days when they have not used khat. They may feel sad, hopeless, or worthless, without a clear reason. They may lose interest in the things they used to enjoy, sleep badly, eat too little or too much, and find it hard to concentrate. These are the signs of depression, and they deserve to be taken seriously, not dismissed as a bad week or a personal failing.
It is important to be careful here. Khat does not cause every case of depression, and many people who feel low have never used khat. Depression has many causes, including life stress, loss, poor sleep, and family history, and it is a health condition that needs proper support. But when a person uses a stimulant regularly, and their mood is low most of the time, the two are likely to be connected, because the stimulant is disturbing sleep, draining the reward system, and adding anxiety and irritability to an already difficult picture. Removing the stimulant will not cure every case of depression on its own, but it removes one of the things that is making it worse, and that gives other kinds of support a better chance to work.
If low mood lasts for more than two weeks, or if it is stopping a person from working, eating, sleeping, or looking after themselves, that is a clear reason to talk to a doctor or another qualified health professional. That advice applies whether or not khat is involved. There is no shame in asking for help with low mood, and there is no weakness in it. Low mood is a health problem, like a broken bone or a bad infection, and it deserves proper care. A health professional can help work out what is going on, what support might help, and how to make a plan that fits the person’s life.
It is also worth saying something directly to anyone who is reading this and recognising themselves in it. If you have been feeling low for a long time, and you have been using khat regularly, you are not alone, and you are not beyond help. Many people have been in the same place, and many of them have recovered, not by willpower alone, but by stopping the substance, getting support, and giving their brain time to heal. The first step is often the hardest, because it means admitting that the problem is real. But admitting it is also the moment when things start to change, and it is a moment worth reaching, however difficult it feels.
My Take:
The thing I keep coming back to with khat and mood is how dishonest the deal is. The lift is real, and I will not pretend otherwise, because pretending would make the rest of what I say easy to dismiss. For a few hours, a person feels brighter, more talkative, and more alive. But the price of those hours is paid in the hours that follow, and the price is higher than the lift was worth. The crash is longer than the high, the flatness lasts longer than the energy, and the anxiety that creeps in stays long after the good feeling has gone. That is not a fair exchange, and I think anyone who has lived through the cycle knows it, even if they find it hard to say out loud.
What frustrates me most is how the mood changes are blamed on the person, not on the substance. A man becomes short-tempered, and his family says he has a bad temper. A woman becomes flat and distant, and her friends say she has lost interest. A young person becomes anxious, and they are told to stop worrying. In each case, the real cause, a stimulant that is pushing the brain’s mood system up and down every day, is missed. I think that is unfair, and I think it stops people from getting help, because they believe the problem is who they are, when the problem is what they are using. Naming the cause does not excuse hurtful behaviour, but it does make the behaviour understandable, and understandable problems can be fixed.
The crash is the part I would most want a new user to understand before they start. Nobody warns you about the crash. The people around the circle are feeling the lift, laughing and talking, and the crash is hours away, in the dark, when you are alone. It arrives as a heavy, empty feeling, and you do not know why you feel so low when nothing bad has happened. That confusion is part of what makes it so hard. You feel sad, but you cannot point to a reason, so you blame yourself. If someone had told you in advance, “You will feel good for three hours and flat for the next twelve,” you might have made a different choice. That is why honest information matters. It does not stop people from choosing, but it lets them choose with their eyes open.
I think about the families a lot, because they are the ones who live with the mood swings every day. A partner who never knows which version of the person will come home. Children who learn to read a parent’s mood before they say hello, because the mood decides what kind of evening it will be. That is a heavy way to live, and it is not the family’s fault. I do not think the person using khat intends to hurt their family. Most of them love their family deeply, and would be horrified to see the effect their mood swings are having. But intention and effect are different things, and the effect is real. If a person is thinking about stopping, the family is the best reason I know, and it is not a selfish reason. It is a loving one.
The flatness is the effect that worries me most in the long term, because it is the hardest to see and the easiest to mistake for something else. A person who feels flat does not look ill. They look bored, or lazy, or uninterested. But inside, their brain has stopped responding to ordinary pleasures, and that is a serious change. Food, friendship, work, and small achievements have all lost their reward, and the only thing that still feels good is the lift from khat. That is a trap, because it makes khat feel necessary, when khat is the thing that caused the flatness in the first place. I wish more people understood that, because it explains why “just stop” is not as simple as it sounds, and why support and patience are needed, not just willpower.
I am honest about the fact that recovery takes time, and I do not want to pretend that stopping will fix mood overnight. In the first weeks, the flatness can feel worse, the anxiety can spike, and the person may wonder whether stopping was a mistake. That is the moment when support matters most, and when honest information can make the difference between giving up and holding on. The brain needs time to reset its reward system, and that time is measured in weeks and months, not days. But the recovery is real. Ordinary pleasures do come back. Food tastes better. A conversation feels warmer. A small success feels satisfying again. I have seen that pattern described again and again, and I believe it, because it matches how the brain works: it adapts to the stimulant, and it can adapt back, if it is given the chance.
If I were talking to someone who uses khat and is starting to notice these mood changes, I would not start with a lecture. I would start with a question: how do you feel the morning after? Not during the lift, when everything feels good, but the next morning, when you wake up flat and tired and irritable. That morning feeling is the truth of the substance, more than the evening feeling is. The evening is the advertisement. The morning is the product. If the morning feels bad most of the time, that is information, and it deserves to be taken seriously. Write it down, look at the pattern over two weeks, and be honest with yourself about what you see. You do not need anyone else to tell you what the pattern means. You will see it yourself, if you look.
I would also say something to the families. If someone you love is using khat and their mood has changed, do not assume they do not care. They may care deeply, and feel ashamed of the way they have been behaving, but not know how to stop. Shame makes people hide, and hiding makes the problem worse. What helps most is calm, honest conversation, without blame, at a time when the person is not in the middle of a lift or a crash. Say what you have noticed, say how it affects you, and say that you want to help, not to punish. That kind of conversation is hard, but it is far more likely to lead to change than anger or silence, and it keeps the door open for the day when the person is ready to ask for help.
Money is part of my thinking too, because mood and money are linked in a way people do not always see. A person whose mood is swinging is less able to work steadily, less able to make good decisions about money, and more likely to spend on khat to feel better. Over a year, that adds up to real money lost, and to real opportunities missed. A person who is flat and unmotivated will not look for better work, or start a small business, or save for their children’s future. They will simply get through the day, and the day after that, and the year will pass without progress. That is a cost that deserves to be counted, because it is not just about feelings. It is about the whole direction of a life, and it is a direction that can change, once the mood starts to steady.
Finally, I want to say this to anyone who has been feeling low for a long time and has started to believe that low is just who they are now. It is not. Low mood is not a personality, and flatness is not a character trait. They are signals that something in the brain’s mood system has been pushed out of balance, and signals can change. The brain can recover, and ordinary pleasures can come back, but only if the thing that is pushing it around is removed, and only if the person gets support while they wait for the recovery to happen. That waiting is hard, and I will not pretend otherwise. But it is worth it, because the reward is not just feeling less bad. It is feeling good again, in the ordinary, everyday way, without needing a substance to get there. That is a feeling worth working for, and it is available to anyone who is willing to take the first step and ask for help.
I also think about the way mood changes can quietly change a person’s decisions, because that is a cost that is easy to miss. A person who feels flat and low does not make bold, hopeful decisions. They put off applying for better work. They avoid starting a small business. They say no to opportunities, not because the opportunities are bad, but because they do not have the energy or confidence to take them. Over a year, those small decisions add up to a life that is smaller than it could have been, and the person may not even notice, because each decision felt reasonable on its own. Steady mood is not just about feeling good. It is about having the energy to build a better life, and khat takes that energy away, a little at a time.
There is something I want to say about young people in particular. A young person whose mood is swinging every day is trying to learn who they are, and that is hard enough without a stimulant pushing their feelings up and down. They may start to believe that the flat, anxious feeling is their real self, and that the bright, talkative feeling during khat use is the only time they are interesting or fun. That belief is wrong, and it is dangerous, because it ties their sense of self-worth to a substance. The truth is the other way round: the flat feeling is the effect of the substance, and the real person is the one who exists underneath it, waiting to be steady again. I wish more young people heard that before they started, rather than after years of use.
I want to be fair here too. Not every mood problem is caused by khat, and I do not want anyone to think that stopping khat will solve every difficulty in their life. Life brings real losses, real stress, and real grief, and those things affect mood whether or not a person uses any substance. But when a stimulant is regularly pushing mood up and down, it makes every other problem harder to face, because the person is facing it with a tired brain, broken sleep, and a reward system that no longer responds to ordinary pleasures. Removing that extra burden does not remove life’s problems, but it gives a person a clearer head and a steadier mood with which to face them, and that is a real advantage.
If someone I cared about told me their mood had become unstable and they used khat regularly, I would suggest a simple experiment, the same kind I would suggest for sleep. Keep a short note each evening for two weeks: how did you feel today, when did you use khat, and how did you feel the morning after? Patterns become obvious when they are written down, in a way they never do when they are only felt. If the low mornings follow the evenings of use, that is information, and it is information the person has gathered themselves, which makes it harder to dismiss and easier to act on. They can then take that note to a health professional and say, here is what I have noticed, and that is a much stronger starting point than a vague feeling that something is wrong.
The final thing I want to leave you with is a thought about hope. A person who has felt flat and anxious for a long time can start to believe that this is permanent, that their brain is broken and will never feel normal again. That belief is understandable, but it is not true. The brain is remarkably able to recover, and the evidence for that is all around us, in the people who stopped, waited through the difficult weeks, and found that ordinary pleasures came back. It did not happen in a day, and it did not happen without support, but it happened. If you are in that flat, low place now, I would ask you to hold on to that one fact: the feeling is not permanent, and the recovery, slow as it is, is real. Asking for help is the first step, and it is a step worth taking.
Frequently Asked Questions
Does Khat cause anxiety?
Yes, regular khat use is linked with anxiety. The stimulant raises alertness and keeps the mind racing, which can feel like worry or being on edge, especially in the hours after use. Over time, anxiety can spread into ordinary days, making it harder to relax, concentrate, or enjoy social situations. Poor sleep makes the anxiety worse, and anxiety makes sleep worse, so the two feed each other. If anxiety is affecting daily life, it is worth talking to a qualified health professional.
Does Khat make anger worse?
It can. Poor sleep, the crash after the lift, and the restless, edgy feeling of the stimulant itself all make a person quicker to snap and less patient with small frustrations. Many regular users find they raise their voice more often, or feel flashes of anger that seem out of proportion, and feel ashamed afterwards. That irritability is a common effect of the substance, not a fixed part of a person’s character, but it can seriously harm relationships at home if it becomes a pattern.
Can Khat cause depression?
Regular khat use is linked with low mood and, in some people, with depression, although depression has many causes and khat is not the only one. The stimulant disturbs sleep, drains the brain’s reward system, and adds anxiety and irritability, all of which can push mood down over time. If low mood lasts for more than two weeks, or stops a person from working, eating, sleeping, or looking after themselves, they should talk to a doctor or another qualified health professional.
Can Khat change your mood?
Yes. Khat can lift mood for a few hours, making a person feel brighter, more talkative, and more confident, and then leave mood lower than before as the effect wears off. With regular use, the lift gets shorter and weaker, while the low mood, anxiety, and irritability last longer. Over time, a person’s normal mood, the mood they have on an ordinary day, can sink, and feelings become harder to trust.
Why does Khat make you feel low afterwards?
The low feeling afterwards is the crash. The stimulant pushes the brain’s reward and alertness chemicals up, and when it wears off, those chemicals fall back down, sometimes below their normal level. Ordinary pleasures stop feeling rewarding, energy disappears, and the person feels flat, tired, and low. Poor sleep after khat makes the crash worse. It is a normal chemical response to a stimulant, not a sign of weakness, and it usually passes, but it returns after each session.
How long do Khat mood changes last?
The lift lasts a few hours, and the crash that follows can last for the rest of the evening and into the next day. With regular use, the broader mood changes, anxiety, irritability, and flatness, can last for weeks or months, because the brain’s mood system has adapted to the repeated stimulation. After stopping, mood usually improves gradually over weeks, as sleep returns and the reward system resets, although the exact time varies, and support from a health professional can help.
