You’re going to be fine. What you’re feeling right now is temporary, it’s not dangerous, and it will pass on its own. Cannabis cannot cause a fatal overdose, and the anxiety or panic you’re experiencing is one of the most common side effects of getting too high. Here’s how to get through it.
Remind Yourself This Has a Timer
The single most helpful thing you can do right now is anchor yourself to the timeline. If you smoked or vaped, the effects started within minutes and will peak within about 30 minutes. After that peak, the intensity drops steadily, and the main effects typically fade within a few hours (though mild residual effects can linger). If you ate an edible, it takes longer: effects can build for up to two hours and peak around the four-hour mark, with the full experience lasting up to 12 hours. Knowing where you are on that curve matters because the worst of it is often the peak, and peaks don’t last.
Repeat this to yourself as many times as you need: “I took a substance. It’s peaking. It will wear off.” That’s not a platitude. It’s the pharmacological truth.
Breathe and Ground Yourself
When panic hits, your attention scatters. Grounding techniques pull it back to the present moment, which is the opposite of spiraling. Start with your breathing: slow, deep inhales through your nose, long exhales through your mouth. Don’t force a count if that stresses you out. Just make your exhale longer than your inhale.
Once you have a rhythm, try the 5-4-3-2-1 technique. It works by flooding your brain with real sensory information, which competes with the anxious thoughts:
- 5: Name five things you can see. A lamp, a stain on the ceiling, your shoe, anything.
- 4: Touch four things and notice how they feel. A blanket, the floor under your feet, your own arm.
- 3: Listen for three sounds. Traffic outside, a fan humming, your own breathing.
- 2: Identify two things you can smell. Walk to the bathroom and smell soap if you need to.
- 1: Notice one thing you can taste. Gum, water, the inside of your mouth.
This exercise is used in clinical anxiety treatment and it’s especially effective during drug-induced panic because it forces your brain to process concrete sensory input instead of looping on fear.
Your Heart Rate Is Probably Fine
A racing heart is one of the most frightening parts of being too high, and it’s also one of the most predictable. THC raises your heart rate and blood pressure. This is a direct pharmacological effect of the drug, not a sign that something is wrong with your heart. Almost everyone who gets too high notices it, and noticing it tends to make the anxiety worse, which makes your heart beat faster, which makes the anxiety worse.
Try placing a hand on your chest and focusing on the sensation of your breathing instead of your heartbeat. If you have a pulse oximeter or smartwatch, checking your actual heart rate can be reassuring since it’s almost always lower than it feels. The elevated rate will come back down as the high fades.
Things That Actually Help Right Now
Several simple interventions can take the edge off. None of them will make you sober, but they can meaningfully reduce the panic.
Sniff or chew black peppercorns. This is not a stoner myth. Black pepper contains a compound called beta-caryophyllene, which is technically a cannabinoid itself. It binds to a different receptor in your endocannabinoid system than THC does, and activating that receptor produces a calming effect. Chewing two or three whole peppercorns or even just sniffing ground black pepper can help level things out. The sharp smell and taste also function as a sensory grounding tool.
Smell or eat something citrusy. A Johns Hopkins study found that d-limonene, the compound that gives lemons and oranges their scent, significantly reduced feelings of anxiety and paranoia caused by THC. Participants who received higher doses of limonene experienced greater anxiety reduction, and the compound didn’t diminish the other effects of THC. You don’t need a supplement. Peel an orange, squeeze lemon into water, or sniff a bottle of lemon juice. The effect is mild but real, and again, the sensory experience itself helps.
Take CBD if you have it. CBD works as a kind of dimmer switch on the same receptor that THC activates. It doesn’t block THC directly, but it changes the shape of the receptor in a way that reduces THC’s ability to bind to it. This is why cannabis products with balanced THC-to-CBD ratios tend to produce less anxiety. If you have CBD oil or a CBD-dominant product, taking some now may soften the intensity. It won’t flip a switch, but it can help over 20 to 30 minutes.
Eat something and drink water. Cannabis can disrupt your blood sugar, and low blood sugar on its own causes anxiety, shakiness, and a racing heart. Those symptoms are easy to confuse with panic when you’re already high. A snack with some protein or complex carbs (peanut butter toast, crackers and cheese, a banana) can stabilize your blood sugar and give you something physical to focus on. Cold water is also grounding. Hold the glass, feel the temperature, drink slowly.
Change Your Environment
If you’re in a loud, crowded, or unfamiliar place, that’s amplifying your anxiety. Move somewhere quieter and more comfortable if you can. A couch, a bed, a porch. If you’re already home, change the stimulus: turn off whatever you’re watching if it feels too intense, put on something familiar and low-key, or switch to calm music. Ambient sounds or nature documentaries work well because they give your brain gentle input without demanding attention.
Fresh air helps more than you’d expect. Step outside or open a window. The temperature change and new sensory input can interrupt a panic spiral. If you’re with someone you trust, let them know what you’re feeling. You don’t need to perform normalcy. Saying “I’m too high and it’s making me anxious” out loud can itself be a relief, and having someone calmly talk to you is one of the most effective ways to stay grounded.
What Not to Do
Don’t consume more cannabis, even if someone tells you a different strain will “balance it out.” Don’t drink alcohol, which can intensify the high unpredictably. Don’t Google your symptoms looking for worst-case scenarios. You’ve already found what you need. And don’t try to fight the high or force yourself to act sober. Resistance increases panic. Acceptance, even reluctant acceptance, reduces it. Let the feeling be weird. You don’t have to enjoy it. You just have to wait it out.
When It’s More Than Just Being Too High
Cannabis-induced panic, while deeply unpleasant, is almost never a medical emergency. However, you should call for help if you experience chest pain (not just a fast heartbeat, but actual pain or pressure), if you can’t breathe, if you’re vomiting and can’t stop, or if you lose consciousness. These situations are rare, but they’re the line between uncomfortable and unsafe.
If you find that anxiety or paranoia happens every time you use cannabis, that’s worth paying attention to. Some people are genetically more sensitive to THC’s effects on the brain’s threat-detection systems. Using lower-THC products, choosing strains with more CBD, or simply using less are all practical adjustments. For some people, cannabis just isn’t a good fit for their neurochemistry, and that’s a perfectly reasonable conclusion to reach.
