You overdid it. It happens. Maybe that gummy took two hours to kick in and you made the classic mistake of eating another, or perhaps that last hit from the bong was way more potent than the "mellow" strain your friend promised. Now the room is spinning, your heart is drumming against your ribs like a trapped bird, and you’re convinced everyone in the grocery store knows. You’re desperate to figure out how to get rid of your high before the panic fully takes root.
The bad news? There isn’t a magical "off" switch that deletes THC from your bloodstream in seconds. The good news? You aren't going to stay like this forever, and there are science-backed ways to dampen the intensity of a bad trip while your liver does its job.
The Biology of the "Green Out"
Cannabis isn't a one-size-fits-all experience. When you inhale or ingest THC (tetrahydrocannabinol), it binds to CB1 receptors in your brain. These receptors are part of the endocannabinoid system, which regulates everything from mood to appetite to how you perceive time. When those receptors get flooded, things get weird. Your amygdala—the brain's fear center—can go into overdrive. That's why you feel that sudden, sharp spike of paranoia.
Edibles are the usual culprits. When you eat cannabis, your liver converts Delta-9 THC into 11-hydroxy-THC. This metabolite is significantly more potent and crosses the blood-brain barrier with much more ease than inhaled smoke. It lasts longer. It hits harder. It’s why you’re sitting on your floor wondering if you'll ever feel "normal" again. (You will).

Why the "Black Pepper" Trick Isn't Just an Old Wives' Tale
If you’re spiraling, go to your kitchen and find the black pepper. This isn't some hippie myth; it's chemistry. Black pepper contains a terpene called beta-caryophyllene. Terpenes are the aromatic compounds found in plants, and cannabis has plenty of them, but so do common household spices.
According to research published in the British Journal of Pharmacology by Dr. Ethan Russo, beta-caryophyllene is a "functional CB2 agonist." In plain English: it binds to some of the same receptors as THC but in a way that can help mitigate the psychoactive effects. Don't snort it—that’s a one-way ticket to a different kind of misery. Just sniff the peppercorns or chew on a few. The spicy, pungent scent can ground you and chemically nudge your brain back toward baseline.
Hydration and the Lemon Connection
Drink water. Not soda, not a massive coffee, and definitely not more alcohol. Alcohol actually increases the concentration of THC in your blood, making the high even more intense. You want cold, plain water.
There's also some anecdotal evidence and minor chemical logic behind lemons. Lemons contain limonene, another terpene that has been studied for its anti-anxiety properties. Squeezing a fresh lemon into your water or even just zesting the peel and inhaling the scent can provide a calming effect. It gives your senses something sharp and real to focus on.
The Myth of "Eating it Away"
People often say that eating a huge meal will help you get rid of your high. This is a bit of a half-truth. While having food in your stomach can slow the absorption of future THC if you've just eaten an edible, it won't suddenly suck the THC out of your blood if you're already peak-high. However, the act of eating can be incredibly grounding.
Choose something simple. A piece of toast. An apple. Avoid super fatty foods if you're feeling nauseous, as the "green out" often involves a heavy, spinning stomach that won't thank you for a greasy cheeseburger.

Changing Your Environment to Kill the Panic
Sometimes the walls feel like they’re closing in because the lights are too bright or the music is too complex. Your brain is over-processing stimuli.
- Turn off the TV. If you're watching a fast-paced action movie or a weird documentary, your brain is struggling to keep up.
- Find a "tether." Pick an object—a soft blanket, a smooth stone, even your own hands. Focus on the texture. Describe it to yourself in your head. The blanket is blue. It feels fuzzy. It is warm. This is a clinical grounding technique used for panic attacks, and it works wonders for a weed-induced spiral.
- Control your breathing. This is the big one. When you're high and panicked, you start shallow breathing. This tells your nervous system you're in danger. Inhale for four seconds, hold for four, exhale for eight. The long exhale is the "hack" that forces your parasympathetic nervous system to kick in and slow your heart rate.
CBD: The Antidote You Might Already Have
It sounds counterintuitive to take more cannabis products to stop being high, but CBD (cannabidiol) is actually a non-psychoactive modulator of the CB1 receptor. Think of THC as a key that fits perfectly into a lock. CBD is like a piece of gum stuck in that lock; it prevents the THC from binding as effectively.
If you have a high-quality CBD oil or tincture (with 0% THC), taking a dose can help "level out" the high. It competes for those receptor sites and can take the "edge" off the paranoia. Just make sure you aren't accidentally taking a "1:1" product that contains even more THC, or you'll just be extending the ride.
The Shower Strategy
A shower can be a gamble, but for many, it’s a reset button.
Keep it lukewarm. A steaming hot shower can sometimes drop your blood pressure and make you feel dizzy or faint, which will definitely escalate your panic. A cool—not freezing—shower provides a "cold shock" response that can snap your brain out of a recursive thought loop. It forces you to focus on the immediate physical sensation of water on skin.
Distraction is Your Best Friend
You cannot "think" your way out of being high. The more you focus on how high you are, the higher you will feel. You need a low-stakes distraction.
- Coloring books: Simple, repetitive motions are great.
- Video games: Something easy like Animal Crossing or Tetris. Avoid anything stressful like Call of Duty.
- Cartoons: There’s a reason people watch Adventure Time or The Simpsons. They are bright, familiar, and generally positive.
- Talking to a friend: If you have a friend who isn't high, call them. Tell them, "I'm way too high and I need you to talk to me about something boring for twenty minutes." Having a calm, sober voice to listen to can be an incredible anchor to reality.
What to Do If Things Get Really Bad
Is it possible to overdose on weed? In the traditional sense—where your breathing stops or your heart fails—no. There has never been a recorded fatal overdose of cannabis in a healthy adult. You are safe. Your body knows how to process this.
However, if you are experiencing chest pains that feel like more than just a fast heartbeat, or if you are completely losing touch with where you are, it's okay to seek help. Most of the time, "help" at an ER for a green out consists of a quiet room, some IV fluids for hydration, and maybe a low-dose benzodiazepine to stop the panic attack. Don't be ashamed to tell a medical professional what you took. They aren't there to arrest you; they're there to make sure you're okay.

Time: The Only Guaranteed Cure
At the end of the day, the only 100% effective way to get rid of your high is time.
If you smoked, you'll likely start feeling significantly better within 60 to 90 minutes. If you took an edible, you might be looking at a 4-to-8-hour window. The peak usually happens about two hours in. Once you pass that peak, you are on the downhill slope. You're going to feel tired, maybe a bit "foggy" or "heavy," but the acute panic will fade.
Immediate Action Steps to Take Right Now
If you are currently feeling too high, follow this sequence to stabilize:
- Stop consuming immediately. Put down the pipe, the pen, or the bag of gummies.
- Grab a glass of water and sip it slowly. Hydration is the foundation of recovery.
- Find three black peppercorns and chew them or sniff a jar of ground black pepper deeply for 30 seconds.
- Lay on your side. If you feel nauseous, the "recovery position" (on your side with one knee bent) prevents accidental choking if you vomit and helps manage the "spins."
- Repeat the mantra: "This is a temporary chemical reaction in my brain. It will be over in a few hours. I am physically safe."
- Set a timer for 30 minutes. Tell yourself you only have to make it to that timer. Often, by the time it goes off, the worst of the peak has passed and you'll feel more in control.
