If you’re too high right now, the most important thing to know is this: what you’re feeling is temporary, it will pass, and nobody has ever fatally overdosed on cannabis alone. Whether you smoked too much or ate an edible that hit harder than expected, you can ride this out safely. Here’s exactly what to do and what to expect.
How Long This Will Last
How you consumed cannabis determines how long you’ll feel this way. If you smoked or vaped, the effects peak within about 30 minutes and can last up to 6 hours total, though the most intense part usually fades well before that. If you ate an edible, the timeline is longer: effects can take 30 minutes to 2 hours to even begin, peak around 4 hours in, and last up to 12 hours. Some residual grogginess can linger up to 24 hours for either method.
If you ate an edible and you’re only an hour in, you may not have hit the peak yet. Knowing that can feel scary, but it also means you can prepare: get comfortable, get water, and settle into a safe spot now.
What to Do Right Now
Find a calm, familiar place. Sit or lie down somewhere you feel safe. If you’re with people who are making the anxiety worse, it’s fine to move to another room or step outside for fresh air.
Focus on your breathing. Inhale slowly, hold for a moment, then exhale slowly. Thinking the words “in” and “out” with each breath gives your mind something simple to latch onto. This directly counteracts the racing heart and shallow breathing that come with being too high.
Drink water or juice. Sip slowly. Having something cold in your hand and something to taste helps bring your attention back to your body in a grounding way. Avoid alcohol and coffee, both of which can amplify anxiety or increase your heart rate.
Eat something. A snack with carbohydrates and a little fat, like toast with peanut butter or crackers and cheese, can help you feel more grounded. Some people feel shaky or lightheaded when too high, and food helps stabilize that sensation.
Grounding Techniques That Work
When your thoughts are spiraling or you feel disconnected from reality, grounding exercises pull your attention back to the present moment. These are techniques therapists recommend for acute panic, and they work well for cannabis-induced anxiety specifically because they redirect your focus away from the high.
The most effective one is the 5-4-3-2-1 method. Working backward from 5, use your senses to list things around you: 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. This forces your brain to engage with your actual environment instead of looping on anxious thoughts.
If that feels like too much, try something simpler. Count backward from 100. Run through a times table. Pick a number and think of five different math equations that equal it. The mental effort required to do math occupies the part of your brain that’s generating panic.
Talk to yourself kindly. This sounds awkward, but repeating simple phrases like “this is temporary” or “I’m safe and this will pass” works. Say it out loud if you’re alone. Your brain responds to reassurance even when it’s coming from you.
Why You Feel This Way
THC, the main psychoactive compound in cannabis, activates receptors throughout your brain that normally respond to chemicals your body produces naturally. These receptors sit on nerve endings and control the release of other brain chemicals, affecting everything from mood to perception to heart rate. When you consume more THC than your system can comfortably handle, it essentially turns the volume up on all of those signals at once. That’s why being too high can feel like anxiety, paranoia, a racing heart, distorted time, and sensory overload all at the same time.
THC also increases impulsive thought patterns, which is part of why your mind may jump to worst-case scenarios. Recognizing that this is a pharmacological effect, not an accurate read on reality, can take some of the power out of those thoughts.
Things That Can Help Take the Edge Off
Smell or eat citrus. Research from Johns Hopkins found that d-limonene, an essential oil naturally abundant in lemons, limes, and oranges, significantly reduced feelings of anxiety and paranoia caused by THC. The effect was dose-dependent, meaning more limonene produced greater relief. Smelling a lemon peel, drinking lemonade, or even just peeling an orange puts this compound to work.
Chew black peppercorns. This is a widely reported remedy among cannabis users, and the mechanism is similar: black pepper contains terpenes that interact with the same receptor system THC activates. Chewing two or three whole peppercorns or even just sniffing ground black pepper can help calm the intensity.
Take a shower. Alternating between warm and cool water gives your body strong sensory input that competes with the overwhelming feelings from THC. It also helps with the clammy, uncomfortable physical sensations many people get when too high.
Watch or listen to something familiar and comforting. A show you’ve seen a dozen times, a favorite album, a podcast you find soothing. Novelty can feel threatening when you’re too high, so lean into the familiar.
What to Avoid While You Wait
Don’t consume more cannabis, even if someone tells you CBD will cancel it out. While CBD can moderate THC’s effects in some contexts, adding anything to the mix right now adds uncertainty. Don’t drink alcohol. It intensifies THC’s effects and can make nausea and dizziness worse.
Avoid grapefruit and grapefruit juice. Grapefruit interferes with the liver enzymes that break down THC, which can slow your body’s ability to process the compound and potentially prolong the high.
Don’t fight the high or try to “think your way out of it.” Resistance tends to increase anxiety. Acceptance, even reluctant acceptance, reduces it. You don’t have to enjoy this. You just have to let it move through you.
When It Might Be More Serious
Cannabis overconsumption is almost never a medical emergency, but there are situations where getting help makes sense. Among people who visit emergency rooms after using cannabis, the most common symptoms are rapid heart rate (reported in about 37% of cases), difficulty breathing, chest tightness, and heart palpitations. If you’re experiencing chest pain that doesn’t ease up, a heart rate that feels dangerously fast and won’t come down with slow breathing, or you’re vomiting repeatedly and can’t keep water down, calling for help is reasonable.
If someone with you becomes unresponsive or is having a seizure, call 911. For non-emergency questions, poison control is available 24/7 at 1-800-222-1222 and handles cannabis calls routinely.
Preventing This Next Time
Most “too high” experiences come from edibles, because the delayed onset tricks people into taking a second dose before the first one kicks in. If you use edibles, start with 2.5 to 5 milligrams of THC and wait at least two full hours before considering more. With smoking or vaping, take one hit and wait 15 minutes to gauge the effect before taking another.
Tolerance varies enormously from person to person based on genetics, body composition, how often you use cannabis, and even what you’ve eaten that day. A dose that barely affects one person can overwhelm another. Keeping track of what amount works for you, and sticking to it, is the most reliable way to avoid ending up here again.
