The most reliable way to stop feeling high is time, but there are several things you can do right now to reduce the intensity and get through it more comfortably. If you smoked or vaped, the peak hits within about 10 minutes and the strong effects typically fade within 3 to 4 hours. If you ate an edible, the peak can take 1 to 2 hours to arrive (sometimes longer), and the whole experience lasts considerably longer. Knowing where you are on that timeline is the first step toward feeling better.
How Long the High Actually Lasts
When cannabis is inhaled, THC reaches your bloodstream within seconds and peaks in plasma concentration around 8 minutes after you start. From there, levels drop steadily and fall to very low concentrations within 3 to 4 hours. The subjective high follows a similar curve: intense for the first hour or so, then gradually tapering.
Edibles are a different story. Your body absorbs THC through the digestive tract much more slowly, with blood levels peaking around 1 to 2 hours after eating. In some cases, that peak can be delayed even further, which is why people sometimes eat more thinking the first dose didn’t work, then get hit with a much stronger high than expected. The total duration of an edible high can stretch to 6 hours or more. If you’re in the middle of an edible experience, know that it will end, but you may need to settle in and ride it out longer than you’d like.
Grounding Techniques That Work Right Now
When you’re uncomfortably high, your mind tends to spiral into anxious, worst-case-scenario thinking. Grounding exercises interrupt that spiral by pulling your attention back to something concrete and manageable. These aren’t magic cures for the chemical effects of THC, but they can significantly reduce the panic and paranoia that make the experience feel unbearable.
Try counting slowly to 10, then backward from 10 to 1. If you still feel tense, recite the alphabet forward and then backward. This kind of simple, sequential mental task gives your brain a structured track to follow instead of looping through anxious thoughts. Another option: look around the room and start sorting or categorizing objects by color, size, or texture. Pick up items near you, notice how they feel in your hands, and describe them to yourself. The goal is to anchor your attention in the physical world around you rather than the racing thoughts inside your head.
Visualizing a place where you feel safe and calm, whether it’s a real location or an imaginary one, can also help. Close your eyes, picture yourself there, and try to fill in sensory details: what you’d hear, what the air would feel like, what you’d see. This works especially well if you’re lying down somewhere comfortable.
Smell or Chew Black Pepper
This is one of the most commonly repeated tips online, and there’s a real reason behind it. Black pepper contains high concentrations of a compound called beta-caryophyllene, which has demonstrated anxiety-reducing effects in multiple animal studies. In mice, it produced calming behavior comparable to a pharmaceutical anti-anxiety medication. The compound interacts with the same receptor system that THC activates, which may explain why it specifically helps with cannabis-related anxiety.
Try chewing a few whole black peppercorns or simply sniffing freshly ground pepper. Some people report near-immediate relief from paranoia. The science on this is still mostly from animal research, so the strength of the effect in humans isn’t fully established, but it’s safe, free, and available in most kitchens.
Try Citrus for Anxiety Relief
Lemons and other citrus fruits are rich in a terpene called d-limonene, and this one has direct human evidence behind it. In a controlled study with adults, d-limonene given alongside THC significantly reduced ratings of feeling anxious, nervous, and paranoid compared to THC alone. The effect appears to come not from blocking THC itself but from limonene’s own calming properties, likely working through the brain’s signaling systems that regulate mood and relaxation.
Squeeze lemon into water and drink it, chew on a lemon rind, or even just peel a citrus fruit and inhale the scent. It won’t eliminate the high, but it may take a real edge off the anxiety component.
Skip the Cold Shower
Cold showers are a popular suggestion, but the evidence doesn’t support them. A study on cold water immersion in cannabis users found that it did not reduce blood THC levels or speed up metabolism of the drug at all. Interestingly, participants actually reported feeling more “stoned” after the cold water exposure, not less, though researchers noted this could have been a placebo expectation or simply the jarring sensory experience amplifying their awareness of being intoxicated.
A cold shower might briefly shock you into alertness, but it won’t help your body process THC any faster and could make you feel worse. A warm shower or bath is a better bet if you want physical comfort.
Eat Something and Stay Hydrated
Drinking water won’t flush THC out of your system, but dehydration makes everything feel worse, especially dizziness, dry mouth, and headaches. Sip water or juice steadily. Eating a snack, particularly something with carbohydrates, can help stabilize your blood sugar and give your body something to focus on besides the high. Toast, crackers, fruit, or a light meal are all good choices. Avoid alcohol, which intensifies THC’s effects.
Will Sleeping It Off Work?
Lying down in a dark, quiet room is one of the best things you can do when you’re too high. Your body continues metabolizing THC whether you’re awake or asleep, so closing your eyes and resting will let time pass without the discomfort of being actively aware of the high. That said, cannabis, particularly when used close to sleep, tends to reduce sleep quality. It increases time spent in light sleep stages and can cause more waking during the night. You may not get the most restful sleep of your life, but you’ll almost certainly feel significantly better when you wake up.
What Edible Overconsumption Feels Like
Edibles cause the most intense overconsumption experiences because the delayed onset tricks people into taking more. The resulting high can include acute anxiety, paranoia, nausea, vomiting, rapid heart rate, and in some cases a feeling of being completely disconnected from reality. Emergency departments have seen patients become unresponsive or acutely psychotic after eating too many edibles, particularly people with no tolerance.
If someone you’re with is vomiting uncontrollably, experiencing chest pain, is unresponsive to voice or touch, or appears to be in a psychotic state (screaming, trying to flee, unable to recognize where they are), that warrants emergency medical attention. For most people, even a very uncomfortable edible experience resolves on its own within several hours, but those specific symptoms cross the line from unpleasant to potentially dangerous, mainly due to dehydration from vomiting or injury risk from altered behavior.
A Quick Summary of What to Do Right Now
- Remind yourself of the timeline. Smoked or vaped highs peak fast and fade within 3 to 4 hours. Edibles take longer but still end.
- Use grounding exercises. Count, sort objects, visualize a safe place.
- Chew black peppercorns or sniff ground pepper for anxiety relief.
- Drink lemon water or smell citrus peel to reduce paranoia.
- Eat a light snack and sip water.
- Lie down somewhere comfortable and let yourself rest.
- Skip the cold shower. It doesn’t help and may make things feel worse.
- Avoid more cannabis, alcohol, or caffeine until you feel normal again.
