There’s no instant off-switch for a cannabis high, but several strategies can take the edge off and help you feel more like yourself faster. The most important thing to know: if you smoked or vaped, the peak hits within about 30 minutes and the main effects typically fade within a few hours. If you ate an edible, the peak can take up to 4 hours to arrive, and effects can linger for up to 12 hours. You’re not stuck forever, even if it feels that way right now.
Try Black Pepper or Citrus
Chewing on a few whole black peppercorns is one of the most commonly recommended home remedies for an overwhelming high. Black pepper contains a compound called caryophyllene, a terpene linked to anxiety reduction. The human evidence is still thin (most studies have been done in animals), but the remedy has a long anecdotal track record and carries essentially zero risk. Chew two or three whole peppercorns slowly, or just sniff freshly ground pepper if chewing sounds unappealing.
Citrus has stronger science behind it. A 2024 clinical trial in humans found that limonene, the terpene responsible for that sharp lemon and orange smell, reduced THC-induced anxiety and paranoia in a dose-dependent way. Higher doses of limonene meant less anxiety. Importantly, it didn’t dull the other effects of THC or change how THC moved through the bloodstream. It specifically targeted the anxious, paranoid feelings. Squeeze fresh lemon into water, peel an orange, or even just deeply inhale the scent of citrus peel.
Use Cold Water to Slow Your Heart Rate
If your heart is racing and panic is building, cold water on your face can help fast. Splashing ice-cold water on your face or pressing an ice pack against your forehead and cheeks triggers what’s called the diving reflex, a built-in response that dramatically slows your heart rate. This reflex works through the vagus nerve, which runs from your brainstem to your heart. A slower heart rate sends a signal to your brain that you’re safe, which can ease the spiral of anxiety.
You don’t need to submerge your whole head. Fill a bowl with cold water and dip your face in for 15 to 30 seconds while holding your breath, or just hold a bag of ice or a cold wet towel across your forehead and cheeks. The effect is almost immediate.
Ground Yourself With Your Senses
When you’re too high, your mind can feel like it’s spinning out of control. Grounding techniques work by pulling your attention out of your head and back into your body. The simplest one to try right now 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. Say them out loud if you can. The act of deliberately cataloging sensory details forces your brain to focus on something concrete.
Other options that work on the same principle: hold a piece of ice in your hand and pay close attention to how the sensation changes as it melts. Run your hands under water, alternating between warm and cold. Savor a strong flavor slowly, like a sour candy or a spoonful of peanut butter, and really focus on the taste and texture. Any activity that anchors you in a specific physical sensation will help.
Don’t Exercise It Off
This one surprises people. Working out to “burn off” a high sounds logical, but research shows it can actually backfire. A study published in Drug and Alcohol Dependence found that moderate exercise on a stationary bike increased THC levels in the blood of regular cannabis users. THC is fat-soluble, meaning your body stores it in fat tissue. When you exercise, your body breaks down fat for energy and releases that stored THC back into your bloodstream. The bump is small, but if you’re already uncomfortably high, it’s the opposite of what you want.
Light movement is fine. A slow walk around the block, some gentle stretching, or pacing around your living room can help burn off nervous energy without triggering significant fat breakdown. Just skip the intense cardio.
Eat Something and Hydrate
Eating a snack or a small meal won’t eliminate your high, but it can soften it. Food helps stabilize your blood sugar, which may be contributing to dizziness or nausea. Starchy, comforting foods like bread, crackers, or pasta work well. Pair that with water or juice rather than alcohol or caffeine, both of which can intensify the effects of THC or add new layers of unpleasant symptoms.
If you’re dealing with dry mouth (cottonmouth), sipping water slowly and steadily helps more than chugging a large amount at once.
Take a Shower
Alternating between warm and cool water in the shower combines several helpful mechanisms at once. The temperature changes give your brain strong sensory input to focus on, pulling you into the present moment. Cool water on your face triggers that same heart-slowing diving reflex. And the simple act of standing up, moving to the bathroom, and going through a familiar routine can break the loop of anxious thoughts. Many people report that a shower is the single most effective thing they’ve tried.
Sleep It Off if You Can
Sleep is the most reliable way to fast-forward through a high, especially from edibles. If you’re able to lie down in a comfortable, familiar space, let yourself drift off. You’ll likely wake up feeling groggy but significantly more clearheaded. Put on a familiar, low-stakes TV show or calm music to help ease you into sleep rather than lying in silence with your thoughts.
How Long You’ll Actually Feel This Way
Your timeline depends entirely on how the THC got into your system. If you smoked or vaped, you’re likely already at or near the peak. Effects from inhalation start within seconds to minutes, peak around the 30-minute mark, and the main high usually fades within 2 to 3 hours. Some residual grogginess can stick around for up to 24 hours, but the intense part is relatively short.
Edibles are a different story. Effects can take 30 minutes to 2 full hours to even begin, and the peak may not arrive until 4 hours after you ate it. The total duration can stretch to 12 hours, with residual effects lingering up to 24 hours. If you took an edible and you’re not sure you’re at the peak yet, avoid taking more. The most common edible mistake is eating a second dose because the first one “isn’t working,” then having both hit at once.
No matter which method brought you here, remind yourself of the timeline. Nobody has ever died from a THC overdose. The discomfort is temporary, and your body will process and clear the THC on its own. Everything you do in the meantime is just making the wait more comfortable.
