What to Do If You Get Too High: A Calm Guide to Cannabis Overconsumption
Last Updated:October, 2026 • Josh
Sometimes cannabis feels different than you expected.
Maybe you took a little more than usual. Maybe an edible took longer to kick in, so you took more before the first dose had really taken effect. Maybe you tried a stronger product than you’re used to. Or maybe your body simply reacted differently this time.
Suddenly, you’re too high.
Your heart may feel like it’s racing. Time may seem strange. You might feel anxious, paranoid, dizzy, nauseated or overwhelmed. You may start wondering whether something is seriously wrong.
First, take a breath.
Cannabis overconsumption can be deeply uncomfortable, but feeling very high does not automatically mean you’re in a medical emergency. The effects of using too much cannabis can include extreme confusion, anxiety, paranoia, panic, a fast heart rate, hallucinations and severe nausea or vomiting. A fatal overdose caused solely by cannabis is considered unlikely, but cannabis can still cause serious impairment, accidents and other medical problems.
The most important thing is to stop consuming more cannabis, get somewhere safe and give yourself time.
- If you’ve had too much cannabis, stop using more and move somewhere safe and comfortable.
- Don’t drive, operate machinery or make important decisions while you’re impaired.
- Edibles can take much longer to fully affect you, which is one reason people sometimes consume more than they intended.
- Anxiety, paranoia, a racing heart, dizziness and nausea can happen when someone consumes more cannabis than their body comfortably handles.
- Avoid adding alcohol or other intoxicating substances to the situation.
- If you’re worried about a possible poisoning or severe reaction, Poison Control can provide immediate guidance at 1-800-222-1222 in the United States.
- If someone has trouble breathing, cannot be awakened, has a seizure or appears to be experiencing another medical emergency, call 911.
First: Stop Taking More
This sounds obvious, but it is one of the most important steps.
Once you've realized you're too high, don't try to balance the experience by taking another cannabis product. Don't take another edible because you think it might somehow change the experience. Don't take another hit because you are trying to find a different feeling.
Give your body time.
This is especially important with edibles. Cannabis eaten or swallowed can take anywhere from about 30 minutes to 2 hours to begin producing noticeable effects, and the full effects can take longer to develop. That delay can make it surprisingly easy to take more before the first amount has fully kicked in.
If you've already taken too much, the answer usually isn't another substance. It's time, safety and support.
Get Somewhere Safe
If you're standing, walking around or out in public, find a safe place to sit or lie down.
A familiar, quiet environment can make an uncomfortable experience easier to manage. If you're with someone you trust, let them know that you've had more cannabis than you intended and that you're feeling uncomfortable.
You don't need to hide it or pretend you're fine.
Cannabis can impair coordination, concentration and decision-making, so avoid driving, biking, swimming, climbing or doing anything where impaired judgment or balance could put you at risk.
If you're alone and feeling overwhelmed, consider contacting someone you trust and letting them know what's happening.
Remind Yourself That the Feeling Will Pass
One of the hardest parts of getting too high is that the experience can feel much bigger than it actually is.
Anxiety can make physical sensations feel threatening. A racing heart can make you worry that something is seriously wrong. Changes in your sense of time can make a few minutes feel much longer.
Try to keep things simple.
You don't have to figure everything out right now. You don't have to fight the feeling. You don't have to force yourself to feel normal.
Find a comfortable place. Breathe slowly. Put on something familiar and calming. Give yourself permission to rest.
The goal isn't to make the effects disappear instantly.
The goal is to stay safe and let your body work through the experience.
If You're Anxious or Panicking
Cannabis can cause or intensify anxiety and panic in some people, particularly when the dose is higher than they're accustomed to. The CDC lists anxiety, paranoia, panic and extreme confusion among signs that someone may have used too much cannabis.
If anxiety starts building, try reducing the amount of stimulation around you.
Turn down the lights. Step away from loud music or a crowded room. Sit somewhere comfortable. Take slow, steady breaths.
You can also remind yourself of a few simple facts:
I took cannabis.
I feel different right now.
I don't need to take anything else.
This feeling will change.
If someone you trust is with you, having them stay nearby can also be reassuring.
Avoid driving somewhere because you think you need to "get out of it." Being impaired can make driving especially dangerous, even if you believe you're capable of doing it.
If Your Heart Is Racing
A faster heart rate can happen after consuming cannabis, particularly when someone has consumed more than they're comfortable with. A racing heart can also feed anxiety, creating a cycle where the physical sensation makes the emotional reaction stronger.
Try to sit or lie somewhere comfortable and focus on staying calm.
Don't respond by consuming more cannabis, alcohol or another intoxicating substance.
If the sensation is severe, doesn't feel like a normal reaction for you or is accompanied by symptoms that concern you, seek medical advice. When in doubt about a possible poisoning or adverse reaction, Poison Control can help you decide what to do next.
If You're Nauseated
Nausea and vomiting can occur after consuming too much cannabis.
Sit somewhere safe and keep yourself comfortable. If you are vomiting repeatedly, becoming increasingly confused, extremely sleepy or experiencing other concerning symptoms, don't try to simply wait it out without getting help.
If you're unsure whether what you're experiencing is a cannabis reaction or something more serious, contact Poison Control or seek medical attention.
Don't Add Alcohol or Other Drugs
When someone realizes they've consumed too much cannabis, there can be a temptation to reach for something else to change the experience.
That's generally not a good time to experiment.
Combining cannabis with alcohol or other substances can increase impairment and may increase the risk of adverse effects.
If you're already uncomfortable, adding another intoxicating substance makes the situation harder to predict.
Keep things simple.
What About Water, Food or Something Sweet?
If you're thirsty, drinking some water is reasonable.
If you feel like eating and your stomach is comfortable, a normal snack may also be fine. But there isn't a food or drink that reliably "sobers you up" from THC.
You don't need to force yourself to eat or drink large amounts in an attempt to cancel the effects.
The main intervention is time.
Your body has to process the cannabis that you've already consumed.
Be Especially Careful With Edibles
Edibles deserve special attention because delayed effects are one of the easiest ways to accidentally consume more THC than intended.
With inhaled cannabis, effects can begin within seconds or minutes. With eaten or swallowed cannabis, effects may take 30 minutes to 2 hours to begin, and the full effects can take several hours to develop.
That creates a common pattern:
"I don't feel anything yet."
So someone takes more.
Then the first amount catches up.
Then the second amount catches up.
Suddenly, the experience is much stronger than intended.
This is one reason Mercy Leaf's harm-reduction approach emphasizes patience rather than chasing an effect.
Our guide to safer cannabis dosing goes deeper into finding a comfortable starting point, while More Isn't Always Better explains why increasing the amount is not always the answer.
When Should You Call Poison Control?
You don't have to figure out everything by yourself.
In the United States, Poison Control can be reached at 1-800-222-1222. The service is free and confidential, and Poison Control recommends contacting them immediately when a poisoning is suspected rather than waiting for symptoms to develop.
This is especially useful if:
- You don't know how much THC was consumed.
- The product contained other substances.
- A child accidentally consumed cannabis.
- Someone consumed a large amount of an edible or concentrate.
- Symptoms are severe or unusual.
- You're unsure whether medical care is necessary.
Have the product package available if possible. Information about the product, ingredients, THC concentration and amount consumed can help healthcare professionals understand what happened.
When Is It an Emergency?
Most uncomfortable cannabis experiences do not require an ambulance, but serious symptoms should never be dismissed simply because cannabis was involved.
Call 911 or seek emergency medical care if someone:
- Has trouble breathing.
- Cannot be awakened or is unresponsive.
- Has a seizure.
- Has severe or persistent symptoms that appear to be getting worse.
- Has suffered a serious injury, such as from a fall or crash.
- Appears to be experiencing another medical emergency.
The CDC specifically recommends calling 911 in an emergency and contacting Poison Control at 1-800-222-1222 when someone shows signs that they may have used too much cannabis.
If a child has consumed cannabis, don't assume that a small amount is harmless. Children can become seriously ill after unintentional cannabis ingestion and may require hospital care.
What Not to Do
When someone is too high, the simplest approach is usually the safest.
Don't:
- Take more cannabis to try to change the experience.
- Mix cannabis with alcohol or other intoxicating substances.
- Drive yourself somewhere.
- Operate machinery.
- Go swimming or put yourself in another situation where impaired coordination could be dangerous.
- Take someone else's medication to try to counteract the cannabis.
- Panic because the experience feels unfamiliar.
- Leave a severely impaired person alone if they may need help.
If you're unsure what to do, ask for help.
There is no prize for trying to tough it out alone.
Why Does This Happen?
People respond to cannabis differently.
The experience can be influenced by the amount of THC, the method of consumption, previous cannabis experience, tolerance, whether you've eaten, other substances or medications, and individual differences in how your body responds.
Two people can consume the same product and have very different experiences.
Even the same person can have a different experience from one day to another.
That's why "I took this much last time and I was fine" isn't necessarily a reliable measure of what will happen today.
How to Reduce the Chances of It Happening Again
Once the experience has passed, it's worth asking what led to it.
Maybe you underestimated the strength.
Maybe you redosed too quickly.
Maybe the edible was stronger than expected.
Maybe you combined cannabis with alcohol.
Maybe you were tired, stressed or in an unfamiliar environment.
Maybe you simply didn't realize how much you had consumed.
The goal isn't to beat yourself up over it.
The goal is to learn from it.
Reading the product label, paying attention to serving size, understanding the difference between inhaled and edible cannabis and giving delayed products enough time before consuming more can all help reduce the risk of overconsumption.
That's harm reduction in practice.
Not perfection.
Not fear.
Just making the next decision a little more informed than the last one.
A Bad Experience Doesn't Mean Cannabis Is Automatically Wrong for You
Having one uncomfortable experience can make someone question the entire relationship they have with cannabis.
Sometimes that reflection is useful.
But one difficult experience doesn't necessarily tell you everything about cannabis or about yourself.
You might have used too much.
You might have combined substances.
You might have chosen a product that was much stronger than what you're accustomed to.
Or you might discover that cannabis simply doesn't agree with you.
All of those are legitimate things to learn.
The important part is paying attention.
If cannabis repeatedly causes significant anxiety, panic, confusion or other problems, that's worth taking seriously rather than simply increasing the amount and hoping the experience changes.
Sometimes the most useful harm-reduction choice is using less.
Sometimes it's changing the way you use it.
Sometimes it's taking a break.
And sometimes it's deciding that cannabis isn't right for you.
Frequently Asked Questions
Maybe with some of the uncomfortable effects, but CBD isn’t a reliable way to come down from a THC high.
Research suggests CBD may reduce some THC-related anxiety or paranoia in certain circumstances, but the results depend on factors such as the amount of CBD, the amount of THC, the timing and the ratio between them. CBD does not simply cancel out THC, and it should not be treated as an antidote to cannabis intoxication.
If you’ve already had too much THC, the safest approach is still to stop consuming more cannabis, get somewhere comfortable and allow time for the effects to wear off.
It’s also worth remembering that CBD products are not necessarily THC-free or accurately labeled. The CDC notes that some products marketed as CBD or hemp may contain THC or other contaminants.
Bottom line: CBD may have a role in how some people experience THC, but don’t rely on it as a rescue remedy when you’ve consumed too much.
You may have heard the old cannabis tip about chewing on a few black peppercorns when you’re feeling too high. There’s an interesting reason the idea exists, but the evidence doesn’t establish black pepper as a treatment for cannabis intoxication.
Black pepper contains β-caryophyllene, a terpene that interacts with the body’s CB2 cannabinoid receptors. β-caryophyllene is also found naturally in cannabis. That connection has led to theories about why the aroma or compounds in black pepper might influence some cannabis-related effects.
But laboratory findings about a compound interacting with cannabinoid receptors are not the same thing as clinical evidence that chewing peppercorns will bring someone down from a strong THC experience.
If you enjoy the smell or taste of black pepper and find it comforting, there’s little reason to make it complicated. Just don’t rely on it instead of the basics: stop consuming cannabis, stay somewhere safe, remain calm and give your body time.
Bottom line: black pepper is an interesting harm-reduction myth with some biological reasoning behind it, but it isn’t a proven antidote to THC.
No, but staying hydrated can help you feel more comfortable.
Water won’t remove THC from your system or instantly end the effects. If you’re thirsty or have a dry mouth, drinking some water is reasonable. There’s no need to force large amounts of water in an attempt to sober up.
The main treatment for an uncomfortable but otherwise uncomplicated cannabis experience is time and supportive care.
Eating may be comforting if you’re hungry and your stomach feels okay, but food isn’t a proven way to reverse THC intoxication.
If you’re nauseated, don’t force yourself to eat. Focus instead on staying comfortable and avoiding additional cannabis or other intoxicating substances.
A shower may help you feel more comfortable or give you something calming to focus on, but it doesn’t remove THC from your body.
If you’re significantly impaired or dizzy, however, be careful around hot water and slippery surfaces. Sitting somewhere safe may be a better option.
No.
If you’ve had more THC than you intended, adding more cannabis makes the situation harder to predict.
This is particularly important with edibles, where effects can take much longer to develop and can last considerably longer than expected.
The better approach is to stop, get comfortable and let the effects wear off.
It depends on what you used, how much you used, how you consumed it and your individual response.
Inhaled cannabis generally comes on more quickly and tends to wear off sooner than an edible, while edible cannabis can take longer to reach its full effect and can last considerably longer.
Don’t use a specific number of hours as a guarantee that you’ll be completely unimpaired. If you still feel impaired, treat yourself as impaired.
If you’re simply tired and otherwise feeling okay, resting somewhere safe may be reasonable.
But don’t assume that every situation can be safely “slept off.” If someone cannot be awakened, has trouble breathing, has a seizure or is experiencing another serious or rapidly worsening symptom, call 911.
If you’re uncertain about a possible poisoning, Poison Control is available 24/7 at 1-800-222-1222.
Don’t take someone else’s medication or experiment with medications to try to reverse a cannabis high.
Some medications can interact with cannabis or cause additional sedation and impairment. If you’re taking prescription medications and are concerned about a reaction, contact a healthcare professional or Poison Control for guidance.
Pay attention to the pattern.
One uncomfortable experience doesn’t necessarily mean cannabis will always cause anxiety, but repeated anxiety, panic or paranoia after cannabis use is worth taking seriously.
If cannabis consistently makes you feel worse rather than better, reducing your use, taking a break or talking with a healthcare professional may be worth considering.
Harm reduction isn’t about finding a way to keep using cannabis no matter what. Sometimes the safer choice is using less, changing your approach or deciding not to use it at all.
When you’re unsure, ask.
Poison Control can help you determine whether symptoms can be monitored at home or whether medical attention is needed. In the United States, call 1-800-222-1222 or use Poison Control’s online service.
Call 911 for trouble breathing, unresponsiveness, seizures or another medical emergency.
Getting too high can be frightening, especially when you don’t know whether what you’re feeling is normal or something more serious.
The first step is simple: stop consuming more and get somewhere safe.
From there, give yourself time. Reduce stimulation. Stay with someone you trust if possible. Don’t drive. Don’t add alcohol or other drugs. And if you’re concerned about poisoning or severe symptoms, ask for help.
Cannabis isn’t risk-free, and pretending otherwise doesn’t help anyone.
Neither does panic or shame.
Harm reduction is about meeting people where they are, giving them useful information and helping them make safer choices with the information they have.
If you’ve had too much cannabis, you don’t need a lecture.
You need a safe place, a little patience and a clear idea of what to do next.
That’s what this guide is here for.
