- My Take:
Khat is a leafy plant that people chew for its stimulating effect. It grows in parts of East Africa and the Arabian Peninsula, and in communities where it is part of social life, chewing sessions can last for hours. The leaves are chewed slowly, and the juice is swallowed, which releases natural stimulants into the body. People who chew khat often say it makes them feel more awake, more talkative and more confident, at least for a while. That feeling is real, and it is also the reason khat can be hard to put down. But the same stimulation that makes a person feel sharp in the moment can, over time, leave the mind feeling slower, foggier and less reliable.
Memory is not one single skill. It is a collection of small jobs the brain does all day without us noticing: holding a phone number in mind long enough to dial it, remembering what someone just said while we answer them, keeping track of where we put our keys, learning a new route, or recalling a name we heard last week. When memory starts to weaken, life does not fall apart in one dramatic moment. It frays at the edges. We repeat a question we already asked. We walk into a room and forget why we went there. We lose the thread of a conversation halfway through. We find it harder to learn something new at work or in class. Each slip on its own seems small, and we blame tiredness or age or a busy week. But when the slips keep happening, and they follow a pattern, it is worth asking what is feeding them.
This article explains, in plain words, what khat does to memory: how it affects the brain while it is being chewed, why short-term memory tends to suffer first, how attention and sleep play a part, and what happens when use goes on for months or years. It is general information, not individual medical advice. If you are worried about your memory, or about your khat use, a qualified health professional is the right person to talk to.
What Khat Is and Why People Chew It
Khat, sometimes spelled qat, is the leaf of a shrub that has been chewed for centuries in Yemen, Ethiopia, Somalia, Kenya and nearby regions. In many of those places it is not a secret habit. It is social. Friends gather in the afternoon or evening, buy fresh bundles of leaves, and chew together while they talk, watch television, play games or simply pass the time. The session can last three, four or five hours. For many people it is a way to relax after work, to bond with friends, or to stay awake through a long night. In some places it is also used before work, because the first lift of energy feels helpful.
The active chemicals in khat are cathinone and cathine. They are stimulants, in the same broad family as the chemicals in some other stimulant drugs, though khat is generally milder than those drugs when chewed in the usual way. Cathinone acts on the brain in a way that increases alertness and energy, and it can lift mood for a short time. That is why a person may feel more awake and more confident during a chewing session, and why work that felt dull an hour earlier can suddenly feel easier. The effect builds slowly, because the leaves are chewed over a long time, and it can last for several hours after the session ends.
The social side matters, because it explains why khat use can become a daily habit without a person ever deciding to use it daily. If all your friends gather every afternoon to chew, staying away can feel like missing out. If chewing is how business is done, or how news is shared, or how a long evening is passed, the habit becomes part of the routine of life. That does not make the person weak or foolish. It makes the habit hard to see clearly, because it is wrapped up in friendship, tradition and belonging. But a habit that is normal in a community can still carry health costs, and memory is one of the places those costs show up.
Khat is legal in some countries and illegal in others, and its legal status varies a great deal from place to place. In the United Kingdom, for example, it has been a controlled drug since 2014. In the United States it is also controlled. In other countries it is sold openly in markets. The law does not change what the plant does to the brain, but it does change how easily people can get honest information and help. Where khat is illegal, people may be less willing to ask a doctor about it. Where it is legal and common, people may assume it is harmless because it is a natural plant. Neither assumption is safe. A plant can be natural and still affect the brain in ways that matter.
How Khat Stimulates the Brain in the Short Term
When khat is chewed, cathinone is absorbed through the lining of the mouth and through the stomach, and it travels in the blood to the brain. There it affects the systems that control alertness, mood and motivation, including the systems that use dopamine and noradrenaline. Dopamine is involved in reward and motivation, and noradrenaline is involved in alertness and the body’s response to stress. By pushing these systems harder, khat makes a person feel more awake, more energetic and more able to concentrate for a short time. Some people also feel less hungry, less tired and more talkative. For a few hours, the world can feel a little brighter and a little easier.
That short-term lift is part of the problem for memory, because it is borrowed energy. The brain is not working better than normal in a lasting way. It is working harder than normal for a short time, and it pays for that effort later. When the stimulant wears off, many people feel flat, tired, irritable and low in mood. Sleep that night is often lighter or shorter, and the next morning can feel foggy. If a person chews again the next day to shake off that fog, the cycle repeats. The brain gets less real rest, and the periods of clear, rested thinking get shorter.
Stimulants also narrow attention in a particular way. During a chewing session, a person may feel very focused on one thing, such as a conversation or a game, and lose track of everything else. That feels like good concentration, but it is not the same as the steady, flexible attention that memory needs. Good memory depends on noticing things properly in the first place. If you are so focused on the feeling of the session, or on one topic, that you do not really register what else is happening around you, you will not remember it later, because it was never properly stored. A person can feel alert and still be a poor listener, because alertness and attention are not the same thing.
There is also the simple matter of time. A chewing session that lasts for hours is hours when the brain is stimulated and not resting. Chewing late into the evening pushes sleep later, and sleep is when the brain does much of its memory work. We will come back to sleep in detail later, but it is worth saying here that the immediate effect of khat and the later effect on sleep are connected. The lift you feel at seven in the evening can be the reason you cannot remember a name at ten the next morning.
Why Short-Term Memory Slips First
Short-term memory, sometimes called working memory, is the brain’s notepad. It holds a small amount of information for a short time while we use it: a number we are about to dial, the first half of a sentence while we listen to the second half, the three items we need from the shop, the name of a person we were just introduced to. It is a fragile system. It needs a calm, rested brain to work well, and it is one of the first things to suffer when the brain is tired, stressed or stimulated in the wrong way.
People who use khat regularly often notice that this notepad gets less reliable. They have to ask someone to repeat themselves more often. They forget what they went to the kitchen for. They start a task and lose track of the steps halfway through. They read a paragraph and realise at the end that they took in almost none of it, so they have to read it again. None of these moments is dramatic on its own. Together they add up to a feeling that the mind is not holding on to things the way it used to.
There are several reasons why short-term memory is vulnerable here. The first is attention. To remember something for even a few minutes, you have to pay attention to it when it happens. Khat can make attention jumpy. A person may feel alert, but their attention keeps moving, and they do not give new information the few seconds of quiet focus it needs to stick. The second reason is sleep, which we will look at in detail. A tired brain drops information more easily, and khat use often means shorter or poorer sleep. The third reason is mood. When a person is coming down from khat, they can feel low, irritable and restless, and a restless mind is a forgetful mind. It is hard to hold a thought still when your mood is pulling you in different directions.
It is important to be honest about what research can and cannot say here. Studies on khat and memory are smaller and less complete than the research on alcohol or tobacco, and many of them look at people who use khat heavily and often, not at occasional users. What the research that does exist tends to find is that heavy, regular use is linked with poorer performance on tests of working memory and attention, and that people who use khat often report more everyday memory slips than people who do not. That does not prove that khat alone causes every slip, because sleep, stress, other substances and general health all play a part. But the pattern is consistent enough to take seriously, especially when the slips follow the pattern of use: worse after long sessions, worse after late nights, worse when use is daily rather than occasional.
Attention, Focus and Following a Conversation
Memory and attention are so closely linked that it is hard to talk about one without the other. You cannot remember what you did not really notice, and you cannot follow a conversation if your attention keeps slipping away from it. Khat affects both sides of that pair. During a session, a person may feel focused, but that focus is often narrow and restless. After a session, attention can feel scattered. The mind jumps from one thing to another, and it is hard to stay with a single task until it is finished.
In everyday life, this shows up in small, practical ways. A person starts to write a message and forgets what they wanted to say halfway through. They are told something important at work and realise, an hour later, that they only remember part of it. They sit down to study or to read and find that their eyes keep moving over the words without the meaning going in. They listen to a friend and nod along, then realise they have lost the thread and do not know what the friend is talking about any more. These are not signs of low intelligence. They are signs of a brain that is finding it hard to hold its attention steady.
Part of the problem is that khat can make a person feel confident about their thinking even when their thinking is not as sharp as they believe. Stimulants can create a feeling of clarity that is not matched by real performance. A person may talk a great deal during a session and feel that they are thinking well, while the people around them notice that they are repeating themselves, jumping between topics, or forgetting what they said a few minutes earlier. That gap between how sharp we feel and how sharp we actually are is one of the quieter harms of stimulants, because it stops us from noticing the problem early.
Over time, the habit of scattered attention can become the normal way the brain works, even on days when the person has not chewed. The brain learns patterns. If it spends many hours a week in a stimulated, restless state, it can find it harder to settle into the calm, steady state that good listening and good remembering need. That is why people who stop using khat often say that their concentration does not come back overnight. It returns gradually, as the brain relearns how to work at its own pace without a stimulant pushing it.
Learning New Things Gets Harder
Learning is memory in action. To learn something new, you have to take in information, hold it in mind, connect it to what you already know, and then store it so you can find it again later. Every step of that chain needs attention, sleep and a settled mood, and khat can disturb all three. That is why learning is often one of the first things to feel harder when khat use becomes regular.
For a student, this can mean reading the same page several times and still not remembering it, struggling to follow a lesson, or finding that revision the night before an exam does not stick. For a worker, it can mean taking longer to learn a new system at work, forgetting the steps of a new task, or making more mistakes when something changes. For someone learning a language, or learning to drive, or picking up a new skill, it can mean slow progress that feels frustrating, because the effort is there but the results are not.
The frustration matters, because it can create a cycle. A person who finds learning harder may feel stressed or low about it, and stress itself makes memory worse. They may chew more khat to feel more alert while they study or work, which can make the next day’s learning even harder. They may start to avoid new challenges, because new challenges mean more chances to forget or to fail. Over months, that avoidance can narrow a person’s life: fewer new skills, fewer opportunities, less confidence. The harm is not just that a fact is forgotten. It is that the person stops trusting their own ability to learn.
It is also worth saying that learning is not only about school or work. It is about everyday life too. Learning a new route, remembering a new colleague’s name, keeping track of a new set of instructions from a doctor, or learning how to use a new phone all depend on the same system. When that system is struggling, everyday life takes more effort, and more effort leaves less energy for everything else. That is why memory problems can feel so tiring, even when the individual slips seem small.
Sleep, Mood and Memory Working Together
Sleep is where memory is sorted and stored. During the day we take in far more information than we can keep, and during sleep the brain decides what to keep, what to file away, and what to let go. Deep sleep and dreaming sleep both play a part in this process. When sleep is short, broken or shallow, that sorting does not happen properly, and the next day’s memory suffers. This is one of the clearest links between khat and memory, because khat and sleep do not mix well.
Khat is a stimulant, and stimulants keep the brain awake. A session that runs late into the evening can make it hard to fall asleep, even when the body is tired. Sleep, when it comes, is often lighter and more broken. A person may wake up several times in the night, or wake up early and be unable to get back to sleep. The next day they feel tired, and tiredness makes attention and memory worse. If they chew again that day to fight the tiredness, the next night’s sleep is disturbed again. After weeks of this, the brain is running on a constant sleep debt, and memory is one of the first things that debt is paid from.
Mood is the third part of this triangle. Khat can lift mood during a session, but the hours after a session often bring the opposite: low mood, irritability, anxiety and restlessness. A low or anxious mood makes it harder to concentrate, and it makes it harder to remember, because the mind is busy with worry or with the feeling of being flat. People who feel low also tend to sleep worse, which makes the next day harder again. It is a loop, and it can turn slowly, over weeks and months, without a person ever seeing the whole shape of it. They notice the poor sleep, or the low mood, or the forgetfulness, but they do not always see how the three are feeding each other.
Breaking that loop does not require a dramatic change all at once, but it does require seeing the loop for what it is. Better sleep, a steadier mood and clearer memory tend to improve together, and they tend to get worse together. That is why advice that focuses on only one part, such as telling a person to try harder to remember, rarely helps. The memory problem is often not a problem of effort. It is a problem of a tired, restless brain that has not had the conditions it needs to store and recall information properly.
When Memory Problems Become Harder to Ignore
Most people can live with a few memory slips. We all forget names, lose keys and walk into rooms for no reason. The question is when the slips stop being occasional and start being a pattern, and when that pattern starts to affect work, study, relationships or safety. With regular khat use, that point can arrive gradually, which makes it easy to miss. There is no single day when memory suddenly fails. There is a slow drift, and the drift is easy to explain away.
Some signs are worth paying attention to. Forgetting appointments or important dates more than once. Having to be told the same thing several times before it sticks. Finding it hard to follow instructions with more than a couple of steps. Losing track of money, or of what has been paid and what has not. Repeating the same story to the same person without realising it. Feeling confused in a familiar place, or struggling to remember a route that used to be easy. None of these on its own proves a serious problem, and any of them can happen for other reasons, including stress, poor sleep, low mood or other health conditions. But if several of them are happening often, and they are getting worse over time, it is worth talking to a health professional rather than waiting and hoping they go away.
It is also worth noticing what other people say. Family and friends often notice memory changes before the person does, because they see the repeats, the missed appointments and the lost threads of conversation from the outside. A partner who says you have told them the same thing three times, or a colleague who notices you keep asking the same question, is not trying to embarrass you. They are giving you information you cannot easily see for yourself. It is easy to dismiss that feedback, especially if it feels like criticism, but it is often the most honest mirror available.
Memory problems can also affect safety. Forgetting to turn off a stove, forgetting to lock a door, forgetting to take an important medicine, or forgetting an instruction at work can have real consequences. That does not mean every forgetful person is unsafe, but it does mean that memory is not only about convenience. It is about being able to look after yourself and the people who depend on you. When memory slips start to carry that kind of risk, getting help becomes more urgent, not less.
Old Memories and Everyday Confidence
Short-term memory gets most of the attention, but khat can also affect how easily a person reaches older memories. A name from years ago, a detail from a family event, a fact learned at school, or a word in a language spoken less often can feel further away than it used to. The memory is often still there, but the path to it feels slower and less reliable. A person may know that they know something, yet be unable to bring it to mind when they need it. That feeling, of a word sitting on the tip of the tongue, becomes more common, and more frustrating.
This matters because older memories are part of who we are. They hold our history, our relationships and our sense of competence. When they become harder to reach, a person can start to feel less sure of themselves. They may avoid conversations where they might be expected to remember something, or they may stop telling stories they used to enjoy telling. They may feel embarrassed when they cannot recall a detail that other people remember easily. Over time, that embarrassment can turn into withdrawal, and withdrawal can make memory worse, because a brain that is used less, and talked to less, has fewer chances to practise recalling.
Confidence is the quiet casualty here. Memory is not only about facts. It is about trust: trust that you will remember what matters, trust that you can learn what you need to learn, trust that you can manage your day without constant reminders. When that trust weakens, everyday life feels less secure. A person may start writing everything down, or asking other people to remember for them, or double-checking everything several times. Those are sensible ways to cope, and they help, but they are also a sign that the brain is no longer doing easily what it used to do easily. The goal is not to feel ashamed of using reminders. The goal is to notice the change, understand what may be feeding it, and get support to address the cause as well as the symptom.
My Take:
I want to start with something simple. Memory is not a luxury, and it is not only about exams or work. It is the thread that holds a day together. It is how you remember that you promised to call your mother, that the rent is due on Friday, that your child has a doctor’s appointment, that you already told your friend that story yesterday. When that thread frays, life does not collapse all at once. It becomes harder in a hundred small ways, and those small ways add up to a life that feels less manageable and less kind. That is why I take khat and memory seriously, even though khat is often talked about as if it were only a social habit or a mild stimulant. A habit that slowly weakens your memory is not a small thing, because memory is not a small thing.
What bothers me most is how quiet this harm is. Khat does not damage memory in the dramatic way that a head injury does. There is no single moment when a person wakes up and cannot remember who they are. Instead there is a slow drift: a name forgotten here, an appointment missed there, a conversation lost halfway through, a page read twice and still not remembered. Each slip is easy to explain away, and each explanation sounds reasonable on its own. I was tired. I was busy. I have a lot on my mind. All of those things may be true, and they may also be the cover for a pattern that is getting worse month by month. By the time the pattern is obvious, months or years of harm have already happened, and the person has already lost chances, time and confidence that are hard to get back.
I also think we need to be honest about why khat is hard to question. In the communities where it is chewed, it is not only a drug. It is friendship, it is tradition, it is how men gather and talk, it is how a long afternoon is passed, it is part of who people are. Telling a person that khat may be harming their memory can feel like telling them that their social life, or their culture, is wrong, and that is not what I am saying. A thing can be part of a culture and still carry a cost, and a person can love their community and still decide that a particular habit is costing them more than it gives them. I would rather people made that decision with clear information than with silence, because silence protects the habit and leaves the person to pay the price alone.
The sleep link is the part I wish more people understood, because it is the most practical and the most hopeful. Khat disturbs sleep, poor sleep weakens memory, and weak memory makes the next day harder, which can lead to more khat to get through the day. That loop is not a mystery, and it is not a moral failing. It is a chain of cause and effect, and chains can be broken at any link. A person who sleeps better will usually remember better, even before anything else changes. A person who chews less, or stops chewing late in the evening, may find that their sleep improves and their memory follows. I am not saying that is easy, and I am not saying it fixes everything, but I am saying that the connection between sleep and memory is real, and it gives people a place to start that is not only about willpower.
I think about students and young workers a lot when I read about this, because they have the most to lose and the least room to lose it. A young person who is trying to learn a trade, pass an exam, or build a career needs their memory working well every day. If khat is making learning harder, the cost is not only a forgotten fact. It is a slower start, a missed opportunity, a qualification not gained, a job not kept. And because young brains are still developing, and because habits formed young tend to last, the choices made at twenty can shape the memory a person has at forty. That sounds heavy, and it is heavy, but I would rather say it plainly than pretend it does not matter. Young people deserve to know what they are trading, so they can decide for themselves whether the trade is worth it.
I am also thinking about families, because memory problems never stay inside one person. When one person forgets appointments, repeats stories, loses track of money or misses what was agreed, the whole household feels it. A partner has to remember for two people. Children have to repeat themselves. Arguments start over things that were said and then forgotten. Trust frays, not because anyone is lying, but because no one can be sure what was agreed any more. That is a sad and lonely place for a family to be, and it is a place that is easy to drift into without noticing. If you are reading this and you recognise that pattern in your own home, I would ask you to take it seriously, not with blame, but with honesty. The memory problem is not the whole story, but it is part of the story, and it will not get better on its own if the cause stays the same.
I do not believe in shaming people who chew khat. Shame does not improve memory, and it does not help anyone stop. Most people who chew regularly did not start because they wanted to harm their memory. They started because it was normal where they lived, because their friends did it, because it helped them stay awake, or because it made a long evening pass more pleasantly. By the time the memory slips appear, the habit is already woven into daily life, and unpicking it takes time, support and patience. A person who wants to cut down or stop deserves help, not judgement, and they deserve information that is honest rather than frightening. Fear alone rarely changes a habit. Understanding, support and a clear reason to change are far more likely to help.
If you are worried about your own memory, I would say this. Notice the pattern, not just the single slip. Write down, for a week or two, when you forget things, and what was happening around that time: had you chewed the night before, had you slept badly, were you tired or stressed? You do not need a perfect record. You need enough to see whether the slips follow your khat use or your sleep. Then talk to a health professional, and be honest about your khat use when you do. A doctor cannot help you properly if they do not know the whole picture, and they have heard this before. They are not there to judge you. They are there to work out what is going on and what might help, and that may include checking for other causes of memory problems as well, because khat is not the only possible cause.
Finally, I want to say something hopeful, because this article would be unfair if it ended only with warnings. Memory can improve. Brains can recover, especially when the cause of the problem is removed and when sleep, mood and daily routine are given time to settle. People who stop using khat often say that their thinking feels clearer after a few weeks, and that their memory improves gradually over months. Not everyone recovers fully, and I will not promise that, because the amount of recovery depends on how long and how heavily a person used khat, and on their general health. But improvement is real, and it is worth working towards. The brain is not a machine that wears out and cannot be repaired. It is a living organ that can heal, slowly, when it is given the chance. Giving it that chance is one of the kindest things a person can do for themselves, and for the people who depend on their memory every day.
I also want to say something about intelligence, because memory problems are so often misunderstood as a lack of intelligence, and that misunderstanding does a great deal of harm. A person who forgets names or loses track of a conversation is not stupid. They are a person whose brain is tired, restless or overstimulated, and whose memory system is not getting the conditions it needs to work well. A clever, capable person can still struggle badly with memory when they are sleeping poorly or using a stimulant every day, and their thinking can sharpen again when those conditions change. Intelligence is not a single test score, and it is not proved by never forgetting anything. It is shown in how a person lives, works, cares for others and solves problems, and none of those things disappears because a name slips away. If you are judging yourself harshly for forgetting, I would ask you to stop and ask a fairer question: is my brain getting the sleep, rest and calm it needs, or am I expecting it to work well while I am giving it the opposite?
There is a practical side to this that I think is worth spelling out, because vague advice to remember better helps no one. If you chew khat, try to notice when your memory is worst. Is it the morning after a late session? Is it in the afternoon, when the lift has worn off? Is it when you have slept badly for several nights in a row? That pattern is information, and it can help you decide where to start. Stopping late sessions is often the easiest first step, because it protects sleep, and sleep protects memory. Eating a proper meal before a session, drinking water, and not chewing on an empty stomach can also help, although none of these things removes the risk entirely. Writing things down, keeping a simple diary, and using reminders on a phone are not signs of failure. They are sensible tools, and they reduce the stress that makes memory worse. The goal is not to become perfect at remembering. The goal is to give your brain a fair chance.
I think about older people too, because memory worries land differently as we get older. An older person who notices more forgetfulness may worry that it is the start of something serious, and that worry can make memory worse, because anxiety itself interferes with attention. Khat use can add to that worry, and it can also mask other causes that need checking, such as poor sleep, low mood, vitamin problems or other health conditions. That is why I would always say the same thing to an older person who is worried: do not try to work this out alone, and do not assume the worst. Talk to a health professional, be honest about your khat use, and let them check the other possibilities as well. A proper check can bring relief, even when the news is not perfect, because knowing what is going on is always better than fearing the unknown.
Finally, I want to speak to anyone who is reading this not for themselves, but for someone they love. Perhaps your partner forgets things, or your father repeats himself, or your friend seems less sharp than he used to be. It is tempting to correct them, or to get frustrated, or to make jokes about their memory. I would ask you to try something else instead. Notice the pattern gently, mention what you have seen without blame, and offer to go with them to talk to a health professional if they are willing. Offer practical help, such as helping them keep a simple routine, or reminding them kindly rather than sharply. And take care of your own patience, because living with someone whose memory is struggling is tiring, and your tiredness matters too. Memory problems affect a whole household, and healing, when it comes, usually comes to the whole household as well, one small, steady step at a time.
One last thought stays with me. A good memory is not about being perfect, and it is not about never forgetting a name or a date. It is about being able to live your day with confidence, to keep your promises, to learn what you need to learn, and to be present for the people you love. If khat is making that harder, the kindest response is not panic and not shame, but honest attention: notice the pattern, protect your sleep, talk to someone you trust, and get proper advice. Your brain has served you for years, through hard work and long days, and it deserves that care in return.
Frequently Asked Questions
Can memory recover after Khat?
Memory can improve after a person stops using khat, but recovery is usually gradual rather than instant. Many people find that their thinking feels clearer after a few weeks, and that short-term memory and concentration continue to improve over months, especially if sleep also improves. How much recovery happens depends on how long and how heavily the person used khat, and on their general health, sleep and mood. Some people recover a great deal, while others still notice some difficulties. There is no fixed timetable, and no one can promise a full return to how things were before. If memory problems continue after stopping, it is worth talking to a health professional, because other causes may also need to be checked.
Can Khat damage your memory?
Yes, regular and heavy khat use is linked with poorer memory, particularly short-term memory and attention. The stimulants in khat can make attention jumpy, disturb sleep, and leave the brain tired the next day, and all of those things make it harder to take in and hold on to new information. Occasional use is less likely to cause lasting problems than daily, heavy use over months or years, but even regular use can lead to more everyday memory slips. The risk is higher when chewing sessions are long, when they run late into the evening, and when sleep is regularly disturbed. This is general information, not a diagnosis for any one person.
How long do Khat memory problems last?
That depends on the person and on their pattern of use. Short-term slips, such as forgetting what was just said or losing track of a task, are often worst in the hours after a session and the morning after a late night, and they may ease once the person has had proper sleep. When use has been heavy and daily for months or years, memory problems can last longer, and they may take weeks or months to improve after stopping. If memory problems are getting worse, or if they do not improve after a period without khat and with better sleep, a health professional should be asked for advice, because other health conditions can also affect memory.
Does Khat cause short-term memory loss?
Khat can make short-term memory less reliable, especially with regular use. Short-term memory is the brain’s way of holding a small amount of information for a short time, such as a phone number, a name just heard, or the first half of a sentence. Khat can disturb attention, so information is not properly taken in, and it can disturb sleep, so information is not properly stored. The result is more frequent slips: repeating a question, forgetting why you went into a room, or losing the thread of a conversation. This is not the same as losing all memory, and it does not mean a person will forget who they are, but it can make everyday life noticeably harder.
Why does Khat make you forget things?
There is no single reason, and several effects work together. First, khat is a stimulant, and it can make attention restless, so new information is not given the quiet focus it needs to stick. Second, it disturbs sleep, and sleep is when the brain sorts and stores memories, so poor sleep means poorer memory the next day. Third, the low mood and irritability that often follow a session make it harder to concentrate. Fourth, long chewing sessions take up hours that could have been spent resting, eating properly or sleeping. Together, these effects leave the brain tired and less able to hold on to information, which is why forgetting becomes more common.
Does Khat affect learning and study?
Yes, khat can make learning and study harder. Learning needs steady attention, good sleep and a settled mood, and khat can disturb all three. A student may find it harder to follow a lesson, harder to remember what was read, and harder to revise effectively.
