If you’re feeling too high right now, the most important thing to know is that this will pass. No one has ever died from cannabis alone, and the uncomfortable feelings you’re experiencing are temporary. The quickest path through it: get somewhere calm, drink water, and focus on slow breathing. Everything below will help you ride it out faster.
How Long This Will Last
How you consumed cannabis determines your timeline. If you smoked or vaped, effects typically peak within 30 minutes of inhaling and can last up to 6 hours total. If you ate an edible, this is a longer ride: effects can take 30 minutes to 2 hours just to kick in, peak around the 4-hour mark, and last up to 12 hours. Knowing this helps because the worst of what you’re feeling right now is not permanent, even if it feels that way. If you ate an edible and it’s only been an hour or two, you may still be climbing toward the peak, so settle in somewhere comfortable.
5 Things to Do Right Now
- Move to a calm, quiet space. Loud music, bright screens, crowded rooms, and unfamiliar environments all make overstimulation worse. Find somewhere you feel safe, dim the lights, and reduce sensory input as much as possible.
- Drink water. Dehydration makes dizziness and nausea worse. Sip water or a non-caffeinated drink steadily. Avoid alcohol, which intensifies THC’s effects and can make you feel significantly more impaired.
- Focus on your breathing. Inhale slowly through your nose for 4 seconds, hold for 4, exhale through your mouth for 4. This activates your body’s calming response and directly counters the racing heart and anxiety that come with being too high.
- Have someone stay with you. If a friend is nearby, ask them to sit with you. Having another person present helps ground you and provides reassurance that you’re okay.
- Sleep if you can. Lying down and closing your eyes is one of the most effective ways to fast-forward through the experience. Even resting without sleeping helps your body process THC more quickly than staying active and anxious.
The Black Pepper Trick
This one sounds odd, but it has real science behind it. Black pepper contains a compound called beta-caryophyllene, one of the most abundant terpenes also found in cannabis itself. Beta-caryophyllene binds to CB2 receptors in your body’s endocannabinoid system, and this interaction can help take the edge off anxiety without producing any high of its own. Try chewing on 2 or 3 whole black peppercorns, or simply sniffing freshly ground black pepper. Many people report noticeable calming effects within minutes. The sensation of smelling or tasting something strong also helps pull your attention out of a panic spiral and back into your body.
Why Lemons and Lemon Peels Help
Citrus fruits, especially lemons, contain a terpene called d-limonene that researchers at Johns Hopkins recently tested in a controlled study with 20 adults. Participants who inhaled d-limonene alongside THC reported significantly less anxiety and paranoia compared to those who received THC alone. The effect was dose-dependent: higher amounts of limonene produced greater anxiety reduction. You can squeeze fresh lemon juice into water and drink it, chew on a lemon wedge (peel included, since that’s where most of the limonene lives), or even just peel a lemon and inhale the scent from the rind.
CBD Can Dial It Down
If you have CBD oil, a CBD tincture, or CBD gummies on hand, taking some can genuinely help. CBD works as a negative allosteric modulator on the same brain receptor that THC activates. In plain terms, it changes the shape of the receptor slightly so that THC can’t bind to it as effectively, reducing both its potency and its effects. This won’t eliminate your high entirely, but it can soften the intensity, particularly the anxious, paranoid, or “too much” feeling. A sublingual oil (held under the tongue) will kick in faster than a gummy, which needs to be digested first.
What Not to Do
Don’t drink alcohol. Combining alcohol with cannabis raises THC blood levels and makes impairment, nausea, and dizziness considerably worse. If you’ve already been drinking, that likely explains why the high feels more intense than expected.
Don’t drive or operate anything mechanical until you feel completely back to normal. Your reaction time, coordination, and judgment are all impaired, even if you feel like you’re coming down. Don’t consume more cannabis to try to “balance it out” or push through to the other side. That’s not how it works, and it will only extend the experience.
Avoid caffeine. Coffee and energy drinks can increase your heart rate and make anxiety worse. Stick with water, juice, or herbal tea.
Grounding Techniques for Panic and Paranoia
If you’re caught in a loop of anxious thoughts or feel detached from reality, grounding exercises can interrupt the cycle. The simplest one: name 5 things you can see, 4 things you can touch, 3 things you can hear, 2 things you can smell, and 1 thing you can taste. This forces your brain to process real sensory information instead of spiraling inward.
Holding ice cubes in your hands or splashing cold water on your face also works. The sharp physical sensation gives your nervous system something concrete to focus on. Some people find that taking a shower (not too hot, not too cold) helps reset the experience. Putting on a familiar, comforting TV show or music you know well can also anchor you to something predictable when everything else feels strange.
Edibles Hit Differently
If you ate an edible and that’s why you’re here, your situation has a few unique features. When you eat cannabis, your liver converts THC into a more potent form that crosses into the brain more effectively. This is why edible highs feel stronger and more body-heavy than smoking. It’s also why they take so long to kick in, which leads to the most common edible mistake: eating more because you thought the first dose didn’t work.
With edibles, the peak can hit 3 to 4 hours after eating. If you’re in the first couple of hours, eating a snack (especially something with fat, like peanut butter or cheese) can slow absorption slightly. Beyond that, the strategies above all apply. The main difference is patience. An edible high that feels overwhelming at hour 2 will feel much more manageable by hour 5 or 6, even if it doesn’t fully resolve for up to 12 hours.
When It’s More Than Just Being Too High
In rare cases, cannabis overconsumption causes symptoms that need medical attention. If you or someone you’re with experiences persistent vomiting that won’t stop, severe abdominal pain with a rigid or swollen stomach, chest pain, signs of dehydration (no urination, extreme dizziness when standing, confusion), or a heart rate that feels dangerously fast and won’t slow down with rest and breathing exercises, those warrant a call to emergency services or a trip to the ER. Heavy, repeated cannabis use can also cause a condition called cannabinoid hyperemesis syndrome, where severe, cyclical vomiting becomes the dominant symptom. Hot showers sometimes temporarily relieve it, but the vomiting itself can lead to dangerous dehydration and electrolyte imbalances.
For the vast majority of people reading this, though, you’re experiencing a bad high, not a medical emergency. It is deeply uncomfortable, sometimes frightening, but it is temporary. Water, a quiet room, slow breathing, and time are your best tools.
