Have you ever consumed cannabis and gotten a little too high for your liking? Or have you ever needed to calm down a friend who consumed too much weed for their tolerance level?
If so, we’ve got you covered. Although an overdose (taking more than what is medically recommended) of delta-9 tetrahydrocannabinol (THC) is not lethal and probably won’t require medical attention, it can lead to severe intoxicating effects and discomfort — particularly if the person affected is new to the cannabis plant or not a regular consumer.
In this guide, we’ll walk you through some general consumption limits for different cannabis products, signs of overconsumption, and how to stop being high if you overconsume. Knowing the ins and outs of counteracting THC effects is a helpful tool in optimizing your cannabis consumption.
Understanding the Effects of Cannabis

For most people, counteracting THC means simply waiting it out. But how long does it take to stop being high? This question’s answer depends on the method you use to consume your cannabis, although researchers have discovered that a THC high generally lasts between 3 and 10 hours.
If you smoke or vape, the effects come on pretty quickly — within minutes — and are known to last anywhere from 1-3 hours on average.
If you ate cannabis edibles, however, and find yourself on a wild ride 3 hours in, you are likely just at your peak and may have another 3-5 hours of effects before they dwindle (typically around 6-10 hours post-consumption, depending on the amount).
Individual biological factors like age, metabolism, sex at birth, weight, fat and water distribution, medications, recent diet, and tolerance all play a role in how long a THC high lasts.
How to Identify the Symptoms of Greening Out
Uncomfortable or mentally taxing effects — even if they’re short-term — are often signs of greening out and can include:
- Anxiety
- Delusions
- Extreme confusion
- Fast heart rate
- Hallucinations
- Increased blood pressure
- Memory issues
- Panic
- Paranoia
- Severe nausea
- Severe vomiting
Tips on How to Sober Up From Weed Fast
While some sources claim that eating high-carb foods or drinking water may help a person come down from greening out, there haven’t been any in-depth studies proving either. The truth is — just like how cannabis use affects everyone differently, what works to counteract cannabis’ psychoactive effects is different for everyone.
If you’re wondering how to stop a bad high, here are 10 common methods cannabis consumers use to stop a weed high.
1. Yoga, Meditation, and Other Relaxation Exercises
Don’t panic — it’s organic! Cannabis is an all-natural substance that carries absolutely no risk of fatality unless an incredibly colossal amount is consumed in a very short period of time (we’re talking close to a hundred thousand milligrams of THC). This makes cannabis less likely to kill you than salt or sugar in smaller amounts. That being said, anxiety and paranoia caused by THC can feel very real and scary. Try some relaxation practices such as yoga, meditation, or breathing exercises to relax and remind yourself that you’re safe.
2. Hydrate!
While there’s no scientific evidence that hydrating reduces the effects of THC, it’s never a bad idea to drink a glass of water. It is generally known that drinking more water increases our metabolism and can help flush toxins from our system. Our bodies are primarily made up of water, and hydrating will help with the undesirable dry eyes and dry mouth that can come with THC ingestion. Be careful not to drink too much water, though. It is also essential to reach for non-alcoholic beverages while you’re high, as increased blood alcohol content (BAC) has been shown to actually increase THC levels and enhance the effects of THC.
3. Work on a Hobby
Maybe yoga isn’t your thing, and that’s okay — any kind of recreational activity that takes your mind off of your current experience will do. For some, this might be painting, playing video games, or reading. For others, it might be sitting outside in nature or scrolling through memes. As long as you’re not driving or using dangerous tools and machinery, doing something you love is an effective and easy way to soothe your mind and make the high go by faster.
4. Snack or Cook a Meal
Many internet sources reference eating high-carb foods in order to weaken the effects of THC, but no evidence exists to support this. However, eating a snack like nuts, crackers, or a sandwich will raise your blood sugar levels and help you feel more level-headed. Avoid consuming any snacks that contain caffeine or sugar, as these are both known to amplify the unpleasant side effects of THC and contribute to negative bodily symptoms like anxiety, increased heart rate, and vomiting.
5. Eat Black Peppercorns
Don’t knock it ‘til you’ve tried it! Black pepper contains terpenes — the aromatic compounds found in cannabis and other plants — that can balance out the effects of THC. Specifically, pepper is full of the terpenes pinene and beta-caryophyllene, which work to calm the anxiety caused by THC’s psychoactive properties. Simply chew on or breathe in the aroma of whole peppercorns or ground pepper to experience instant sedating effects.
6. Shower or Bathe
Have you ever woken up so tired that you had to splash yourself in the face with cold water to snap out of it? The same principle applies to taking a cold shower, which will take your attention away from the intoxicating feelings. Conversely, a warm bath can help relax your body and mind. Although taking a shower won’t reduce the amount of THC in your blood, it will definitely divert your senses away from the THC’s effects and help clear your head.
7. Try CBD Products
Can cannabidiol (CBD) counteract THC effects? It sure can! The theory behind this is that CBD has very different properties and interacts with different receptors than its cousin THC, so it holds the potential to balance out some of THC’s effects. When CBD and THC are ingested together, they work synergistically within our bodies’ endocannabinoid systems to reduce feelings of anxiety and fear that some users experience from THC alone. Simply take some CBD oil, capsules, or gummies and give your system time to settle.
8. Drink Caffeine
You’re not crazy — in tip #4, we direct you away from consuming caffeine during a bad high. That’s because research on combining cannabis and caffeine is still limited, and the practice has been found to enhance highs for some while reducing them for others. While caffeine intake shouldn’t be your first step in battling a heavy high, its stimulating properties are a good option if you find yourself fatigued from the THC and in need of an energy boost. Just make sure to start with small amounts.
9. Take a Long Walk
Who doesn’t love a good walk? As long as the weather is decent, a short walk can be very enjoyable and therapeutic. While a walk won’t necessarily have any effect on your high, it’s an easily accessible way to soothe your nerves, get some fresh air, stretch your legs, and adjust your mindset. After all, movement is medicine.
10. Sleep
If all else fails, take a nap! We mentioned earlier that time is the only guaranteed way to end your high, so sleeping will allow you to pass the time without experiencing your high in full force. Research has found that the cannabinoids in cannabis help promote sleep, so you’ll likely have no problem hitting the hay in the middle of your high. Sleep will also help reset your system and leave you feeling better in general when you wake up. For an extra dose of relaxation, open your window and turn on the fan to promote fresh air in the room.

How Will You Know If You’re Too High?

A typical THC high will produce feelings of euphoria, introspection, relaxation, and often hunger. While a high will often feel strong and sense-altering, some consumers find themselves feeling scared, overwhelmed, or physically ill if they consume too much THC. If you want to learn more about the various factors that go into how long a cannabis high lasts, check out this article.
As with anything you consume, it is important to know your limits before you dive in! Just like you need to know your drinking limits before consuming alcohol at the bar or how much pie you should be eating before heading to Grandma’s for Thanksgiving, it’s important to have a clear idea of how much cannabis you can handle to help you avoid overconsumption and unpleasant impairment.
When it comes to inhalation, or smoking cannabis flower, a couple of puffs is a good start. If you don’t experience unwanted effects from this amount of cannabis consumption, you can work your way up from there. Most consumers who are new or first-time cannabis users can tolerate a few hits and, after consuming more regularly, can smoke a bowl or joint without the fear of overconsuming.
Consuming cannabis concentrates requires a bit more caution, as concentrates hold much higher amounts of THC than flower. As a concentrate newbie, look for products with low THC content (less than 70%). When using a vape pen, one of the mildest concentrate products, start with a puff and work your way up. Dab rigs or pens, on the other hand, produce a much more intense high and should be approached more carefully.
Cannabis Hangovers
Cannabis hangovers? Yes, it’s a thing. The day after smoking cannabis, you might find yourself experiencing some unpleasant symptoms, though not quite the same ones that you’d get with a hangover from alcohol.
The feeling of a “hangover” will differ from person to person and may not happen at all for you, but some common feelings include:
-dry mouth
-dry eyes
-mild nausea
-fatigue
-headaches
-brain fog
If you want to ease a cannabis hangover, you may find success with methods such as getting sleep, staying hydrated, and using OTC pain medications.
