How Does Amphetamine Affect Your Appetite and Weight

One of the most reliable effects of amphetamine is that it takes away appetite. Food stops looking appealing, hunger stops feeling urgent, and meals are skipped without any real sense of missing them. For a person who is using amphetamine regularly, that may not feel like a problem at first. They may even welcome it, especially if they are busy or if they have been told that eating less is a good thing. But the body still needs food every day, and when appetite is switched off for weeks and months, the harm builds quietly. Weight drops, energy falls, thinking gets foggy, and the body becomes weaker and less able to fight off illness. This article explains how amphetamine changes appetite and weight, why those changes matter, and what happens when eating is disrupted for a long time. It is general information about side effects and harms, not personal medical advice, and it does not tell anyone how to use amphetamine. If you are worried about your own health, or about someone close to you, a qualified health professional is the right person to talk to.

It helps to start with a simple fact: appetite is not a weakness, and hunger is not an inconvenience. Hunger is the body’s way of saying it needs fuel, and appetite is the signal that makes eating feel pleasant and satisfying. When those signals are working properly, a person eats enough to keep their energy steady, their brain working, their muscles strong and their immune system ready. When amphetamine suppresses those signals, the body does not stop needing food. It simply stops asking for it clearly. That is why the weight loss that follows is not the same as losing weight through healthy eating. Healthy weight loss leaves a person with enough energy and nutrients to live well. Weight loss from a suppressed appetite leaves the body short of both, and the difference shows up in tiredness, poor concentration, frequent illness and a general feeling of being run down.

The other thing to understand is that this is not only about the number on the scales. Two people can lose the same amount of weight and be in very different states of health, depending on what they were eating, how much sleep they were getting, and how long the pattern went on. A person who skips meals for weeks is not only lighter. They are also short of the vitamins, minerals and protein the body needs to repair itself, to keep the heart steady, to keep the brain sharp and to keep bones strong. Those shortages do not always show up straight away, which is why they are easy to miss. But they are real, and they are the reason appetite loss from amphetamine is a serious harm, not a convenient side effect.

How Amphetamine Switches Off Hunger

Amphetamine affects the parts of the brain that control hunger and fullness. It increases the activity of chemicals such as dopamine and noradrenaline, which sharpen alertness and reduce the feeling of hunger at the same time. The result is that a person can go for hours without thinking about food, even when their body has had very little to eat. A meal that would normally look appealing may look uninteresting, and the stomach may feel tight or unsettled rather than empty. That is not because the body does not need food. It is because the brain’s hunger signal has been turned down, and the body is running on stimulation instead of fuel.

This effect is strongest while the drug is active, which can be for many hours. During that time, a person may drink a cup of tea or coffee, work through lunch, and not notice that they have eaten almost nothing all day. When the drug wears off in the evening, hunger can return suddenly and strongly, and the person may eat a large amount in a short time, often choosing sweet or fatty foods that are quick and easy. That pattern, very little food during the day and a large amount late at night, is hard on the body, because it swings blood sugar and energy up and down, and it does not give the body a steady supply of nutrients through the day. Over weeks, the daily total of food eaten falls, even if some evenings feel like a lot of eating, because the daytime meals that should have provided most of the day’s nutrition are missing.

With regular use, the problem deepens. The brain becomes used to the drug’s effect on appetite, and the natural hunger signal becomes weaker even between doses. A person may wake in the morning with no interest in breakfast, skip lunch without thinking about it, and eat only a small evening meal, and that pattern can feel normal from the inside, because the body has adjusted to it. From the outside, the change is often obvious: clothes become looser, the face looks thinner, and friends and family start to comment that the person is not eating properly. That is usually a sign that the appetite signal has been suppressed for long enough to matter, and it is worth taking seriously rather than explaining away as being busy or not feeling hungry.

Why Food Stops Tasting Good

Amphetamine does not only reduce hunger. It can also change how food tastes and feels, which makes eating even less appealing. The drug dries the mouth, so food can feel dry and hard to swallow, and flavours can seem dull or strange. A meal that a person used to enjoy may taste bland, or even unpleasant, and the pleasure of eating, which is one of the things that normally encourages a person to finish a meal, simply is not there. When eating stops being enjoyable, it becomes a chore, and chores are easy to put off, especially when a person is feeling wired, restless or tired.

Nausea adds to the problem. Amphetamine can unsettle the stomach, and many people feel sick or queasy while the drug is active, particularly if they try to eat a large meal. That nausea makes the idea of food unappealing, and it can lead to a person eating less and less, until they are eating only small amounts of whatever is easiest, such as biscuits, crisps or sweet drinks, rather than a proper meal. Those foods provide quick energy but very little of the protein, vitamins and minerals the body needs, so the person can feel full for a short time while still being undernourished in the ways that matter most for health.

The jaw and teeth can make eating harder too. Amphetamine can cause the jaw to clench and the teeth to grind, which can leave the jaw sore and aching, and that soreness makes chewing uncomfortable. A dry mouth also increases the risk of tooth decay and gum problems over time, and sore gums or sensitive teeth can make a person avoid foods that need chewing, such as meat, bread and raw vegetables, and choose soft, sweet foods instead. That narrows the diet further, and the body gets even less of the nutrients it needs. None of these effects is dramatic on its own, but together they explain why a person using amphetamine regularly can go from eating three proper meals a day to eating almost nothing, without ever making a conscious decision to stop eating.

Skipped Meals and the Slow Drop in Weight

When meals are skipped day after day, weight drops, and the drop can be fast. The body first uses the energy stored from recent meals, and then it starts to use its own reserves: first the stored fat, and then, if the shortage goes on, the muscle as well. That is why weight loss from appetite suppression is not the same as losing fat through exercise and healthy eating. A person can lose muscle as well as fat, and that loss of muscle makes them weaker, less steady on their feet, and less able to do physical work or even simple tasks like carrying shopping or climbing stairs. The loss is often most obvious in the face, the arms and the legs, where the body looks thinner and less strong than it used to.

The speed of the weight loss can be alarming, and it is often the first sign that other people notice. Clothes that fitted a month ago may hang loose. A belt may need extra holes. A person’s face may look drawn, and their cheekbones may stand out more than they used to. That change in appearance can be upsetting for the person themselves, and it can also be a sign of something more serious underneath: the body is not getting enough food to maintain itself, and it is drawing on its own tissues to keep going. That is a state the body can manage for a short time, but not for months, and the longer it goes on, the harder it is to recover from, because the body has less and less to draw on.

It is worth being clear that this weight loss is not a benefit, even if a person wanted to lose weight. Losing weight because appetite has been switched off is losing weight while also losing the nutrients the body needs to stay healthy. A person who loses weight in that way may feel tired, cold, dizzy and weak, and they may find that their hair becomes dull or falls out more than usual, and that their skin becomes dry or breaks out. Those are signs that the body is short of food in a general way, not just short of calories. The scales only tell part of the story. The rest of the story is told by how the person feels, how they look, and how well their body is coping with the demands of daily life, and when appetite is suppressed for weeks, that story is usually one of gradual decline.

Blood Sugar, Energy and the Crash Cycle

Food provides the steady energy the body runs on, and when food is missed, that energy supply becomes unsteady. Blood sugar, which is the level of sugar in the blood that the brain and muscles use for fuel, rises after eating and falls between meals. When meals are regular, those rises and falls are gentle, and energy stays fairly steady through the day. When meals are skipped and then replaced by a large amount of sweet food late in the day, blood sugar swings sharply: it rises quickly, then falls quickly, and that fall brings tiredness, shakiness, irritability and difficulty concentrating. That is the crash cycle, and it is a common experience for people whose eating has been disrupted by amphetamine.

The crash is made worse by the drug itself. Amphetamine provides a feeling of energy that is not based on food, so a person can feel alert and active while their blood sugar is actually low, and they may not notice the warning signs, such as shakiness, sweating or feeling faint, until they are quite pronounced. When the drug wears off, the tiredness that has been hidden underneath arrives all at once, and it can feel overwhelming. The person may feel exhausted, hungry and low in mood, and they may crave sweet food or more of the drug to lift themselves out of that feeling. That craving is understandable, but it keeps the cycle going, because the sweet food gives a short lift and then another fall, and the drug gives a short lift and then another crash.

Over time, that cycle wears the body down. Energy becomes less predictable, so a person may feel wired one hour and exhausted the next, and they may find it hard to plan their day, because they cannot rely on how they will feel. Thinking suffers too, because the brain is very sensitive to changes in blood sugar, and a brain that is short of fuel cannot concentrate, remember or make good decisions. Sleep is affected as well, because a large late meal, or a body that is hungry and wired at the same time, makes it hard to settle at night. The result is a day that feels unstable from morning to night, and that instability is not a personal failing. It is what happens when the body’s fuel supply is disrupted for weeks on end.

Thirst, Dry Mouth and Forgetting to Drink

Amphetamine dries the mouth and can make a person forget to drink, which is a harm that is easy to overlook but important to understand. Water is as essential as food, and the body loses water all day through breathing, sweating and passing urine. When a person is using amphetamine, they may sweat more, their heart may beat faster, and they may be more active, all of which increase water loss, while at the same time they feel less thirsty and less interested in drinking. That combination can lead to dehydration, which means the body does not have enough water to work properly.

Dehydration has clear effects. It causes headaches, dizziness, tiredness and difficulty concentrating, and it makes the mouth and lips dry and sore. It can cause constipation, because the gut needs water to move food through properly, and it can make urine dark and infrequent. It also makes the heart work harder, because there is less fluid in the blood for the heart to pump, and that extra work is added to the strain the drug already places on the heart. In hot weather, or during heavy activity, dehydration can become dangerous, because the body cannot cool itself properly without enough water, and body temperature can rise to a level that needs urgent medical attention.

The dry mouth itself causes problems that go beyond thirst. Saliva protects the teeth and gums, and when the mouth is dry for hours every day, the teeth are more vulnerable to decay, and the gums can become sore and inflamed. A sore mouth makes eating harder, which adds to the appetite problem, and it can make talking uncomfortable too. Some people try to deal with a dry mouth by drinking sugary drinks, which can quench thirst for a short time but add to tooth decay and to the blood sugar swings described above, without providing the steady hydration that plain water gives. The simple point is that amphetamine disrupts drinking as well as eating, and the body pays for both, in tiredness, headaches, heart strain and dental problems that build up over time.

What Poor Eating Does to the Body Over Time

When the body is short of food for weeks and months, the effects spread far beyond weight. The immune system, which defends the body against infection, needs a steady supply of protein, vitamins and minerals to work properly. When those are missing, colds and infections come more often, last longer, and take more out of the person. Small cuts and bruises heal more slowly, and the person may feel generally run down, as though they are always on the edge of being ill. That is not a coincidence. It is the body saying, in the only way it can, that it does not have what it needs to defend and repair itself.

Muscles and bones are affected too. Muscle is built and maintained with protein from food, and when protein is missing, muscle is lost, which makes the body weaker and less steady. Bones need calcium and vitamin D, among other nutrients, to stay strong, and a diet that is short of those nutrients, combined with poor sleep and low body weight, can weaken bones over time. That is a particular concern for young people, whose bones are still growing, and for older people, whose bones are already becoming more fragile. Hair, skin and nails also show the shortage: hair becomes dull and thin, skin becomes dry or breaks out, and nails become brittle, because the body is prioritising the organs that keep it alive over the parts that show on the outside.

The brain is affected as well, and that is often the part people notice most in daily life. The brain uses a large share of the energy from food, and when that energy is short, thinking becomes slower and less reliable. Memory gets patchy, concentration fades quickly, and mood becomes more volatile, because the brain does not have the steady fuel it needs to regulate itself. That is one reason poor eating and poor mood often go together, and why a person who is not eating properly may feel more anxious, more irritable and less able to cope with stress. The body and the mind are not separate here. They are running on the same fuel, and when the fuel is short, both suffer.

Young People, Growth and Missed Meals

Young people are especially vulnerable to the appetite and weight effects of amphetamine, because their bodies are still growing and need a steady supply of food to do so. Teenagers and young adults need more energy and more nutrients than adults of the same weight, because they are building bone, muscle and brain tissue at the same time as they are living active lives. When appetite is suppressed during those years, growth can slow, and the body may not reach the height and strength it would otherwise have reached. That is a loss that is difficult to recover later, because the years of growth do not come back.

School and college are affected too. A young person who is not eating properly finds it harder to concentrate in class, harder to remember what they have learned, and harder to stay awake through the day. They may feel tired and irritable, and they may fall behind in their work, not because they are not trying, but because their brain is short of fuel. Sport and physical activity become harder as well, because the body is weaker and less steady, and injuries take longer to heal. Friends and teachers may notice the change in appearance and in energy, and that attention can be embarrassing and isolating, which adds to the stress that makes eating even harder.

It is also worth saying that young people are more likely to be influenced by ideas about weight and appearance, and that can make appetite loss from amphetamine seem like a good thing, when it is not. Losing weight because food has become unappealing is not the same as being healthy, and it is not a safe way to change how the body looks. The body needs food to grow, to think and to stay well, and no change in appearance is worth the cost of weakening the body that has to carry a person through the rest of their life. Anyone who is worried about a young person who is losing weight and not eating properly should talk to a health professional, who can check their health and offer support without judgement.

When Eating Starts to Return

When a person stops using amphetamine, appetite usually returns, but it does not always return smoothly. Hunger may come back suddenly and strongly, and the person may feel very hungry for a while, even after eating a normal meal. That is the body’s way of making up for the shortage, and it can be confusing, because the person may eat large amounts and still feel hungry, or they may crave sweet foods in particular. That is a normal part of recovery, and it usually settles over weeks as the body’s hunger signals become steady again, although the exact length varies from person to person.

Weight also returns, but not always evenly or quickly. Muscle that has been lost takes longer to rebuild than fat, and it needs regular food and gentle activity to do so, not just extra calories. A person who has lost a lot of weight may find that their weight returns before their strength does, and that can be frustrating, because they look healthier but still feel weak and tired. That is a normal part of the process, and it is one reason recovery takes time. The body rebuilds itself gradually, and it needs steady food, steady sleep and time, rather than sudden changes or extreme diets.

There is one more thing worth saying honestly here. When appetite returns, some people worry that they will gain too much weight, or that they will lose control of their eating, and that worry can make them return to the drug. That fear is understandable, but it is not a reason to keep using amphetamine, because the drug is doing far more harm than the weight gain ever could. A health professional can help a person through this part of recovery, by talking through what to expect, by checking that eating is becoming regular again, and by offering support if the worry about weight becomes difficult to manage. Eating properly again is not a failure. It is the body healing, and it deserves to be welcomed, not feared.

My Take:

What strikes me most about amphetamine and appetite is how easily a serious harm can look like a benefit. In a world that praises thinness and treats eating less as a virtue, a drug that takes away hunger can seem helpful, even desirable. I think that is a dangerous misunderstanding, and I want to say so plainly. Losing weight because your body has stopped asking for food is not the same as being healthy. It is the body being starved quietly, and the cost is paid in energy, strength, thinking and resistance to illness. The scales do not tell you whether you are healthy. They only tell you how heavy you are, and a person can be light and very unwell at the same time. That distinction matters, and I think it is worth repeating until it is clear.

I also think about how invisible this harm is at first. A skipped lunch is nothing. A skipped breakfast is nothing. But a month of skipped lunches and breakfasts is a body that has missed dozens of meals, and that is a serious shortage. The harm is invisible because it is spread out, day by day, in small amounts, and because the person does not feel hungry, they do not feel that anything is wrong. That is the trick of appetite suppression: it removes the very signal that would warn you. Hunger is not an enemy. It is a warning system, and when it is switched off, the body loses its way of saying it needs food. I think that is one of the most important things a reader can understand from this article. If you are not feeling hungry, that does not always mean you do not need food. It can mean the signal has been silenced, and the need is still there, growing quietly underneath.

The crash cycle is the part I find most exhausting to think about, because it is so wearing to live through. A person feels wired and alert, then suddenly tired, shaky and hungry, then wired again, then tired again, and the day becomes a series of swings rather than a steady rhythm. That instability makes everything harder: work, study, conversation, sleep, even simple decisions. A brain that is short of fuel cannot think clearly, and a body that is short of fuel cannot feel steady, and the combination leaves a person feeling as though they are always catching up and never quite getting there. I do not think that is a personal failing. It is what happens when the fuel supply is disrupted, and it is a predictable result, not a surprise. Naming it as a cycle, rather than as a series of bad days, helps, because a cycle can be understood and broken, while a series of bad days just feels like bad luck.

Young people worry me most here, and I will be honest about why. A teenager who is still growing needs food more than an adult does, and losing that food during the years of growth is a loss that is hard to make up later. It is also a time when ideas about weight and appearance are powerful, and when a drug that suppresses appetite can seem like an answer to a problem that is really about confidence and belonging, not about food. I think adults have a responsibility to be clear about this: no change in appearance is worth weakening a growing body, and no young person should be left to work that out alone. If you are a parent, a teacher or a friend, and you notice a young person losing weight and skipping meals, do not wait for them to ask for help. Ask them how they are, listen to what they say, and talk to a health professional if you are worried. That conversation could matter more than you know.

I want to say something about the return of appetite, because it is a part of recovery that is rarely talked about honestly. When appetite comes back, it can feel overwhelming. A person may feel very hungry, they may crave sweet food, they may worry about gaining weight quickly, and they may be tempted to go back to the drug to switch the hunger off again. I understand that temptation, and I do not think it makes a person weak. But I also think it is important to say that the return of hunger is a good sign. It means the body is asking for food again, and that is the body healing. The hunger will settle. The weight will steady. The strength will return, slowly, and the tiredness will ease. Recovery is not a straight line, and it is not fast, but it is real, and it is worth going through, even when the first weeks feel uncomfortable.

Support matters here too, and not only for the person who is using amphetamine. Families who watch someone they love lose weight and stop eating properly are carrying a heavy worry, and they often do not know what to say or how to help. Offering food is not enough, because the problem is not that food is unavailable. The problem is that appetite has been switched off, and the person does not feel hungry. What helps is steadiness: regular meals offered without pressure, honest conversation without blame, and a willingness to talk to a health professional together. A doctor or a support service can check the person’s health, talk through what to expect when appetite returns, and offer guidance on rebuilding regular eating in a way that is safe and sustainable. That help is available, and asking for it is a sensible step, not a sign that anyone has failed.

I am also honest about the fact that I do not have a simple answer for the fear of weight gain after stopping. That fear is real, and it is felt by many people, and dismissing it does not help. What I can say is that the weight gained in recovery is the body returning to the weight it needs to function properly, and that is a different thing from gaining weight through overeating. A health professional can help a person understand what a healthy weight looks like for them, and can offer support if the worry about weight becomes difficult. The alternative, continuing to use a drug that suppresses appetite, is not a solution to weight worry. It is a way of hiding the worry while the body gets weaker underneath, and that is a much worse bargain in the long run.

One more thought stays with me, and it is about how we talk about food in general. Food is often treated as a problem, as something to control, to cut back, to feel guilty about. But food is also fuel, medicine and comfort, and the body needs it every day to do the work of living. A person who eats regular, nourishing meals is not indulging themselves. They are giving their brain, their heart, their muscles and their immune system what they need to work. I think that is a healthier way to think about eating, and it is a way of thinking that makes the harm of appetite suppression clearer. When amphetamine takes away appetite, it does not only take away meals. It takes away the fuel that makes a normal, active, healthy life possible, and that is a serious loss, even if it does not look dramatic from the outside.

Finally, I want to end with the hopeful part, because there is one, and it matters. Appetite can return. Eating can become regular again. Strength can be rebuilt. Energy can become steadier. Thinking can become clearer. None of that happens overnight, and it takes time, food, sleep and support, but it does happen, and it happens for people who have eaten very little for a long time. The body is remarkably good at recovering when it is given what it needs, and the first step is simply to give it food, regularly, without shame or fear. If you are reading this because you are worried about yourself or about someone you love, that first step is worth taking, and it is worth taking today, not at some distant point in the future when things feel easier. They will not feel easier on their own. They will feel easier when the body is fed, rested and cared for, and that starts with a meal.

I also want to say something about the everyday practical side of eating again, because advice about food can sound simple and still be hard to follow. When appetite has been switched off for weeks, the idea of three full meals a day can feel overwhelming, and that is normal. Recovery does not have to start with a perfect diet. It can start with small, regular steps: a piece of toast in the morning, a bowl of soup at midday, a simple evening meal eaten slowly and without pressure. What matters most at first is regularity, not perfection. The body needs to learn again that food arrives at predictable times, and that it can rely on that supply. Over weeks, as appetite returns, meals can become larger and more varied, and the body will start to tell the person what it needs more clearly. A health professional or a dietitian can help with that process, especially if the person has lost a lot of weight or has other health problems, but the basic principle is simple: eat little and often, eat at regular times, and be patient with a body that is relearning how to be hungry.

There is another point that deserves honesty, and it is about how long recovery takes. I have said several times in this article that recovery is gradual, and I want to be clear about what gradual means in practice. It does not mean a week. It usually means weeks and months, and for some people it means longer still, depending on how long and how heavily they were using, and on their general health. That can sound discouraging, and I understand why. But I think it is more encouraging, in the end, than a false promise of a quick fix, because a person who expects a slow recovery is less likely to give up when the first week feels hard. The body heals at its own pace, and that pace is set by biology, not by willpower. The best thing a person can do is to give it steady food, steady sleep, steady support, and time, and to notice the small improvements as they come, even when they are modest. A little more energy this week than last week is real progress, and it is worth recognising as such.

Finally, I think it is worth speaking directly to anyone who is reading this article because they are worried about a friend or a family member who is not eating properly. You may feel helpless, and you may feel that offering food is pointless when the person does not want to eat. But your attention matters more than you think. Noticing the weight loss, noticing the skipped meals, noticing the tiredness and the change in mood, and naming what you see, gently and without blame, can be the first step that helps the person see the pattern themselves. You do not need to have all the answers. You only need to be honest about what you have noticed, and to offer to go with them to talk to a health professional if they are willing. That offer, made with care and without pressure, is one of the most useful things one person can do for another, and it costs nothing except the courage to speak up. If you are that person, do not underestimate what your noticing can do.

One last thought, then, is simply this: food is not the enemy, and hunger is not a flaw to be switched off. They are the body’s way of keeping itself alive and well, and a drug that silences them is doing harm even when it feels convenient. If this article helps one person see that clearly, and helps them ask for support a little sooner than they otherwise would have, then it has done its job.

Frequently Asked Questions

How does Amphetamine affect appetite and weight?

Amphetamine suppresses appetite by affecting the brain’s hunger signals, so food stops feeling interesting and meals are skipped without the person feeling particularly hungry. When that happens day after day, the body uses its own reserves, and weight drops, often quickly, along with muscle as well as fat. The harm is not only about weight. The body also becomes short of the nutrients it needs for energy, thinking, strength and resistance to illness, so the person feels tired, foggy and run down, even if they do not feel ill in any specific way.

How soon can Amphetamine start harming appetite and weight?

Appetite can fall within hours of taking amphetamine, and meals can be skipped from the first day of regular use. Weight loss can begin within days or weeks, depending on how much is eaten and how often the drug is used. Other harms, such as low energy, poor concentration and frequent illness, build more slowly, over weeks and months, as the body becomes short of nutrients. Because the early signs are easy to explain away as being busy or not feeling hungry, the pattern can be well established before anyone names it as a problem.

Can the harm Amphetamine does to appetite and weight be reversed?

Appetite usually returns when use stops, and weight and strength can be rebuilt over time with regular food, rest and support, although the exact length varies from person to person. Some effects, such as lost muscle and weakened bones, may take much longer to improve, and some changes may not fully reverse, depending on how long the pattern went on. A qualified health professional can assess an individual situation, which is the only safe way to get a personal answer. What is clear is that stopping gives the body its best chance to heal, and that regular eating is the foundation of that healing.

Who notices the harm of Amphetamine on appetite and weight first?

Family members and close friends often notice the harm first, because they see the small daily changes in mood, sleep, appetite and reliability. The person using Amphetamine may be the last to see it, since the brain adapts to the pattern and the change feels normal from inside. Colleagues, teachers and neighbours may also notice, in missed days, shorter patience and work that is no longer steady. That difference in perspective is common, and it is one reason honest conversations with people who care can be helpful, even when they are difficult to hear.

What makes the harm of Amphetamine to appetite and weight worse?

Using Amphetamine more often, in larger amounts or over a longer time generally increases the harm, because the body gets less chance to recover. Poor sleep, skipped meals and existing health problems can also make the harm worse, because the body is already under strain. Mixing Amphetamine with other substances can multiply the danger, especially for breathing, the heart and consciousness. Dehydration, sugary drinks and a diet of only quick snacks can add to the harm too, because they leave the body short of the nutrients it needs while also swinging blood sugar up and down.

Where can I read reliable information about Amphetamine and appetite and weight?

Reliable general information about Amphetamine can be found from public health authorities such as NIDA, the NHS, the WHO, the CDC and the DEA, listed in the sources below. For questions about a specific person, the right step is a conversation with a qualified health professional, not an article. Those sources explain harms, risks and patterns of use in plain language, without selling anything or offering personal advice.
