You can’t instantly cancel a marijuana high, but you can shorten it and make it far more manageable. When smoked or vaped, a high typically lasts 2 to 3 hours. Edibles take longer, with effects persisting 6 to 10 hours, though most people feel normal by the next day. Everything below is designed to help you ride it out faster and more comfortably.
Remind Yourself It Will End
The single most useful thing you can do right now is accept that the high is temporary. No one has ever stayed high forever. If you smoked, the peak is already passing within 30 to 45 minutes. If you took an edible, the intensity will climb for about an hour or two and then gradually fade. Knowing the timeline can prevent the spiral of anxiety that makes being too high feel unbearable.
Try a Grounding Exercise
If your thoughts are racing or you feel panicky, grounding techniques can pull your attention back to the physical world. The simplest one is the 5-4-3-2-1 method: name 5 things you can hear, 4 things you can see, 3 things you can touch from where you’re sitting, 2 things you can smell, and 1 thing you can taste. This forces your brain to process concrete sensory input instead of looping on anxious thoughts.
Another option is to say an anchoring statement out loud: “My name is [full name]. I’m [age] years old. I live in [city]. Today is [day of the week]. It’s [time].” Keep adding mundane details until you feel calmer. Running simple math problems in your head, like counting backward from 100 by sevens, works on the same principle. It gives your brain a task that competes with the anxiety.
You can also run your hands under water, alternating between warm and cold, and focus entirely on how the temperature changes feel against your skin. Any activity that forces you to pay close attention to a physical sensation will help.
Eat Something and Drink Water
Staying hydrated won’t sober you up, but dehydration makes dizziness, dry mouth, and brain fog noticeably worse. Sip water or juice steadily. A light snack with some carbohydrates and fat, like toast with peanut butter or crackers with cheese, can help stabilize your blood sugar and give you a small sense of physical normalcy. Many people report that eating a meal helps take the edge off, especially with edibles.
Sniff or Chew Black Pepper
This is one of the most widely recommended home remedies, and there’s a biological reason behind it. Black peppercorns contain a terpene called beta-caryophyllene that interacts with the same receptor system THC targets. Chewing two or three whole peppercorns, or simply sniffing ground black pepper, can reduce feelings of anxiety and paranoia. The effect isn’t dramatic, but many people find it takes the sharpest edges off within a few minutes.
Try Lemon Peel or Citrus
Lemons and other citrus fruits are rich in limonene, a terpene with promising evidence for reducing THC-induced anxiety. A study from Drexel University found that when limonene was combined with THC, participants reported significantly less anxiety, nervousness, and paranoia, with the strongest calming effect at higher limonene doses. That study used vaporized limonene, but the compound is concentrated in citrus peel. Zesting a lemon into hot water or simply chewing on a piece of lemon rind is worth trying. The sharp, bright smell alone can help redirect your senses.
Use CBD If You Have It
CBD works as a negative allosteric modulator of the same brain receptor THC activates. In plain terms, it changes the shape of that receptor slightly so THC can’t bind to it as effectively. If you have a CBD tincture, gummy, or vape cartridge on hand, it can genuinely blunt the intensity of the high. A sublingual tincture (held under the tongue) absorbs fastest, typically within 15 to 20 minutes. This is one of the more reliable options if you happen to have CBD available.
Take a Shower
A change in physical sensation can interrupt the feedback loop of discomfort. A cool or lukewarm shower gives your body a cascade of new sensory input to process, which naturally pulls your focus away from the high. If a shower feels like too much effort, even splashing cold water on your face or holding an ice cube in your hand can help ground you.
Go for a Walk or Change Your Environment
Light physical movement can help your body metabolize THC a bit faster, and a change of scenery resets your mental state. A short walk around the block, stepping onto a porch, or even moving to a different room can feel surprisingly effective. The key is gentle activity. Intense exercise while very high can increase your heart rate in ways that feed anxiety rather than relieve it. Stay close to home and keep it easy.
Distract Yourself
Put on a familiar TV show, a playlist you love, or a simple video game. Anything engaging enough to occupy your attention without being overstimulating will help the time pass faster. Avoid horror movies, intense dramas, or doom-scrolling the news. Comfort content is your friend right now. Some people find that drawing, coloring, or doing something repetitive with their hands works especially well.
Sleep It Off
If you can sleep, sleep. It’s the single most effective way to fast-forward through a high. Lie down in a dark, comfortable room, put on some ambient music or white noise, and let yourself drift. If your mind is too active to fall asleep, focus on slow breathing: inhale for four counts, hold for four, exhale for six. Even resting with your eyes closed in a quiet space will help your body process the THC.
What Won’t Work
Cold showers, coffee, and energy drinks are commonly suggested, but caffeine can increase your heart rate and worsen anxiety. It won’t counteract THC in any meaningful pharmacological way. Forcing yourself to vomit after eating an edible is also unlikely to help, since THC is absorbed relatively quickly through the stomach lining and intestines. Once you feel high, the THC is already in your bloodstream.
When the High Feels Dangerous
A marijuana high is extremely unlikely to cause a medical emergency on its own, but heavy or repeated cannabis use can occasionally trigger a condition called cannabinoid hyperemesis syndrome, which involves severe, uncontrollable vomiting. If you’re experiencing repeated vomiting along with signs of dehydration (dark or very little urine, dizziness, rapid heartbeat, fainting, sudden confusion, or extreme sleepiness), that warrants a trip to the emergency room. The risk isn’t the THC itself; it’s the dehydration that prolonged vomiting can cause.
Chest pain, difficulty breathing, or a sense that you genuinely cannot distinguish reality from hallucination are also reasons to call for help. These situations are rare, but they’re real, and they’re nothing to feel embarrassed about.
