If you’re too high right now, the most important thing to know is that it will pass. A cannabis high from smoking or vaping typically peaks within 20 to 30 minutes and fades within 2 to 3 hours. An edible high takes longer, peaking around 2 to 4 hours after you ate it, but it also ends. You are not in danger, and there are several things you can do right now to take the edge off and feel more comfortable while you wait.
What to Do Right Now
Stop consuming any more cannabis immediately. This sounds obvious, but if you’re sharing with friends or have edibles sitting nearby, put them away. Every additional bit will extend and intensify what you’re feeling.
Next, focus on your breathing. Inhale slowly through your nose and exhale through your mouth. Place your hands on your stomach and watch them rise and fall as your belly expands and contracts. This activates your body’s calming response and directly counteracts the racing heart and tightness in your chest that come with being too high. Do this for at least a full minute before trying anything else.
If you’re spiraling into anxious thoughts, use a grounding technique: wiggle your toes, press your hands flat against a table or chair, and name five things you can see in the room. These physical sensations pull your attention back to the present moment. You can also count backward from 100 by sevens, or mentally walk through your to-do list for tomorrow. The goal is to give your brain a concrete task so it stops looping on the anxiety.
Chew Black Peppercorns
This is one of the most widely repeated tips online, and it has real science behind it. Black pepper contains a compound called beta-caryophyllene, which is actually the most abundant terpene found in cannabis extracts. Beta-caryophyllene activates a specific receptor in your body (CB2) that doesn’t produce any psychoactive effects on its own but can help modulate the overall experience, offering a sense of mental clarity and calm.
You don’t need to eat a handful. Chew on two or three whole black peppercorns, or simply sniff freshly ground pepper. The combination of the sharp sensory jolt and the chemical interaction can help ease paranoia and mental fog. Even if the pharmacology takes a few minutes to kick in, the intense flavor and smell work as an immediate grounding tool.
Try Lemon or Citrus
Citrus fruits contain a terpene called limonene, and a 2024 clinical study found that it selectively reduces THC-induced anxiety. When participants received limonene alongside THC, their ratings of feeling “anxious,” “paranoid,” and “unpleasant” dropped significantly compared to THC alone. The effect was dose-related: more limonene meant less anxiety.
To try this at home, squeeze fresh lemon into water and drink it, or chew on a piece of lemon rind (that’s where the highest concentration of limonene lives). Orange peel works too. Limonene on its own produced no noticeable effects in the study, so there’s no risk of making things worse.
Eat Something and Drink Water
A light snack can help you feel more grounded. Simple carbohydrates like crackers, bread, or fruit give your body something to process and can ease nausea. Many people report that eating helps “dull” the high, and at minimum, it gives your body a competing sensation to focus on.
Drink water or juice steadily. Cannabis commonly causes dry mouth, and dehydration amplifies feelings of dizziness and disorientation. Avoid alcohol, which intensifies THC’s effects and can make nausea much worse. A glass of cold water also serves as a sensory anchor, something real and tangible to hold and sip while you ride it out.
Change Your Environment
If you’re in a loud, crowded, or overstimulating space, move somewhere quieter. A different room, fresh air outside, or even just sitting on the floor with your back against a wall can shift your mental state noticeably. Your surroundings play a huge role in how a high feels, and a calm environment reduces the chance that normal stimuli get amplified into something overwhelming.
Put on familiar, relaxing music or a TV show you’ve watched before. Novelty can feel threatening when you’re too high, but something predictable and comforting gives your brain a safe track to follow. A warm shower or a cold washcloth on the back of your neck can also help reset your senses.
Talk to Someone
Remind yourself out loud that you are safe and that this is temporary. It sounds simple, but self-talk is a legitimate psychological technique for managing acute anxiety. Say the words: “I took too much cannabis. I’m not in danger. This will be over in a couple of hours.”
If you’re with someone you trust, tell them what you’re feeling. Having another person calmly confirm that you’re okay provides external reassurance that your anxious brain can’t dismiss as easily as your own thoughts. If you’re alone and feeling panicky, text or call a friend. You don’t have to tell them you’re high if you don’t want to. Just hearing a familiar voice helps.
How Long This Will Last
Your timeline depends entirely on how you consumed the cannabis. If you smoked or vaped, THC hit your bloodstream within seconds and peaked in your blood within about 8 minutes. The subjective high peaks around 20 to 30 minutes after your last inhale, then tapers steadily. You should feel noticeably better within an hour and mostly normal within 2 to 3 hours.
Edibles are a different story. THC from food takes 30 to 90 minutes to even begin producing effects, and the high peaks somewhere between 2 and 4 hours after you ate it. In some cases, effects don’t fully dissipate for up to 24 hours, though the intense peak typically lasts a few hours. If you ate an edible recently and aren’t feeling anything yet, do not take more. The most common cause of an overwhelming edible experience is re-dosing before the first dose kicks in.
What Not to Do
Don’t try to “counteract” the high with caffeine, energy drinks, or stimulants. These increase your heart rate and can amplify anxiety and paranoia. Don’t drive or operate anything dangerous. Don’t take a hot bath if you’re dizzy, since your blood pressure may already be lower than usual and heat can cause you to faint.
Don’t fight the high by trying to act sober or forcing yourself into complex tasks. This creates frustration and feeds the anxiety loop. Surrender to the situation, get comfortable, and let your body metabolize the THC at its own pace. Trying to resist the feeling often makes it feel more intense, not less.
If Someone Else Is Too High
Help them get to a comfortable, quiet spot. Offer water and a snack. Speak calmly and remind them that what they’re feeling is temporary and not dangerous. Watch for vomiting, since the main physical risk of “greening out” is choking if someone is lying on their back. If they need to lie down, put them on their side. In the vast majority of cases, being too high on cannabis resolves completely on its own with nothing more than time, comfort, and reassurance.
