If you’re feeling too high, the most important thing to know is that it will pass. A cannabis high from smoking or vaping typically lasts up to 6 hours, with peak effects hitting within 30 minutes. Edibles last longer, up to 12 hours, with peak effects around the 4-hour mark. Nothing will instantly make you sober, but several techniques can take the edge off and help you ride it out more comfortably.
Slow Your Breathing First
The fastest way to calm your body during an intense high is controlled breathing. Breathe in through your nose for a count of six, then out through your mouth for a count of eight, letting your belly expand on the inhale and contract on the exhale. This activates the vagus nerve, a long nerve running from your brain to your gut that acts as a brake pedal for your stress response. Just a few minutes of this pattern can slow your heart rate and ease the panicky, racing feeling that comes with being too high.
If breathing alone isn’t enough, try splashing cold water on your face or finishing a shower with 30 seconds of cold water. Cold exposure triggers what’s called the dive reflex, which slows your heart rate and redirects blood flow to your brain. It’s a physical reset button that works whether or not you’re high, and the shock of cold water also gives your mind something concrete to focus on instead of spiraling.
The Black Pepper Trick
You’ve probably seen this one online, and there’s a reason it keeps circulating. Chewing on a few black peppercorns or even just sniffing freshly ground pepper is one of the most commonly reported home remedies for cannabis-induced anxiety. The idea centers on a terpene called caryophyllene, which is abundant in black pepper and is associated with reducing anxiety symptoms. The honest caveat: clinical trials in humans haven’t been done, and the existing research is mostly in animals. But the remedy has a long history of anecdotal support, it’s safe, and it costs nothing to try.
Limonene Has Stronger Evidence
Lemons may actually do more than peppercorns, and there’s now a human trial to back it up. A 2024 study gave 20 healthy adults vaporized THC alongside varying doses of d-limonene, the terpene responsible for the citrus smell in lemons, oranges, and lemon rind. At the highest combined dose, participants reported significantly lower ratings of feeling “anxious/nervous” and “paranoid” compared to THC alone. Notably, limonene didn’t dull the other effects of THC or cause any side effects on its own.
You won’t get the concentrated dose used in that study from squeezing a lemon into water, but limonene is most concentrated in citrus peel. Zesting a lemon into hot water, chewing on a lemon rind, or even just deeply inhaling the scent of fresh lemon peel are all ways to get some exposure. At minimum, the sensory experience gives your brain something pleasant to focus on.
CBD Can Blunt the Intensity
If you have CBD oil or a CBD-dominant product on hand, it can help moderate the high. CBD works as what pharmacologists call an allosteric modulator of the same brain receptor that THC activates. In plain terms, it doesn’t block THC directly but changes the shape of the receptor so THC can’t bind to it as effectively. This is why high-CBD cannabis strains tend to produce a milder, less anxious experience. A few drops of CBD oil under the tongue won’t instantly sober you up, but it can soften the intensity over 20 to 30 minutes.
Simple Comforts That Actually Help
Beyond specific remedies, basic physical comfort does real work. Eat something. Food won’t speed up THC metabolism, but a snack helps stabilize blood sugar and gives you a grounding sensory experience. Stick to something simple and familiar. Drink water, not because dehydration caused your high, but because dry mouth is uncomfortable and sipping water is a calming, repetitive action.
A gentle neck and shoulder massage, even self-administered, activates the same vagus nerve pathways as deep breathing. Going for a short walk outside can also help. Nature and fresh air create a sense of openness that counteracts the claustrophobic feeling of being too high, and mild physical movement helps your body process adrenaline. Leave your phone behind if you can. Scrolling while paranoid rarely makes things better.
Putting on familiar, comforting music is another surprisingly effective tool. Music you already know and love gives your brain a predictable pattern to follow, which works against the disorientation of being overly high.
What to Avoid
Skip caffeine. Coffee and energy drinks increase your heart rate, which is already elevated from THC. Adding stimulants to an anxious high makes the physical symptoms worse. Alcohol is also a bad idea, as it can intensify THC’s effects and increase nausea and dizziness.
You may have heard that eating a mango before or during cannabis use makes the high stronger because of a terpene called myrcene. In practice, mangoes contain far too little myrcene to have any real pharmacological effect. A mango has roughly 0.09 to 1.29 mg of myrcene per kilogram, while cannabis flower can contain 25 mg per kilogram or more. So if you want a mango, eat one, but don’t worry that it’s going to make things worse.
How Long Until It’s Over
If you smoked or vaped, the peak is already happening or has already happened within the first 30 minutes. The most intense part will start fading within an hour or two, though some residual grogginess can linger for up to 24 hours. If you ate an edible, you may still be climbing toward the peak for up to 4 hours after ingestion, and the full experience can stretch to 12 hours. This is why edible overconsumption feels so much more overwhelming: you can’t gauge the peak in advance, and the duration is roughly double that of inhaled cannabis.
Sleeping it off is genuinely one of the most effective strategies if you’re able to. Lie down in a dark, quiet room, focus on your breathing, and let yourself drift. You’ll feel significantly better when you wake up.
Signs That Need Medical Attention
The vast majority of “too high” experiences are uncomfortable but not dangerous. However, certain symptoms warrant a call to 911 or a trip to the emergency room: chest pain, a fast or irregular heartbeat, difficulty breathing, being unable to wake someone up, or extreme confusion and paranoia that doesn’t improve. Hallucinations, meaning seeing or hearing things that aren’t there, and temporary psychotic symptoms can also occur with very high doses and may require professional help to manage safely.
If you or someone you’re with is vomiting repeatedly after cannabis use, especially if it’s a recurring pattern, that may be a condition called cannabinoid hyperemesis syndrome, which requires medical attention to prevent dangerous dehydration.
