If you’re too high right now, the most important thing to know is that the feeling will pass and there are concrete steps to bring yourself down faster. If you’re planning ahead, there are ways to control your experience so you don’t end up uncomfortably intoxicated in the first place. Both situations have practical solutions.
If You’re Too High Right Now
The single most effective thing you can do is change your environment and focus your senses on something other than the high. A grounding technique called 5-4-3-2-1 works well for this: identify five things you can see, four you can touch, three you can hear, two you can smell, and one you can taste. This pulls your attention out of the anxious spiral and back into the physical world around you. Don’t overthink it. Look at the colors and textures of objects nearby and really describe them to yourself.
If that feels like too much, try something even simpler: count slowly to ten, or recite the alphabet. When your mind is flooded with worst-case thoughts, anchoring it to familiar, factual sequences gives it something stable to hold onto. You can also clench your fists tightly for ten seconds, then release. Giving that anxious pressure a physical outlet and then letting it go can make the mental tension feel lighter. Repeat as needed.
Deep, slow breathing helps on a physical level. Breathe in through your nose for four counts, hold for four, and exhale through your mouth for six. Focus on the sensation of air moving through your nostrils or your belly rising and falling. This directly counteracts the rapid heart rate and shallow breathing that make a too-intense high feel like a medical event.
Beyond grounding, keep it simple: drink water, eat something (a snack with sugar and fat can help), move to a calm and comfortable space, and put on familiar music or a show you’ve seen before. Chewing on black peppercorns is a well-known folk remedy in cannabis culture, and there’s a plausible reason it may help. Pepper contains a terpene called beta-caryophyllene that interacts with the same receptor system THC targets. A few chews or even just sniffing cracked pepper is low-risk and worth trying.
Why You Can’t Exercise It Away
A common piece of advice is to go for a run or do jumping jacks to “burn off” the high. This is one of the rare cases where intuition leads you in the wrong direction. A study published in Drug and Alcohol Dependence found that moderate aerobic exercise actually increases THC levels in the blood by releasing stored THC from fat cells. The effect was small (less than 1 ng/mL), but it moved in the opposite direction of what most people expect. The increase was more pronounced in people with higher body mass. So while a gentle walk to change your scenery is fine, intense cardio is not a reliable way to come down.
How Long the High Lasts
Your timeline depends entirely on how you consumed THC. When inhaled, THC reaches the brain within six to ten minutes, peaks quickly, and typically fades within one to three hours. The bioavailability of inhaled THC is 10% to 35%, meaning your body absorbs a significant portion very fast, but the experience also resolves relatively fast.
Edibles are a different story. The bioavailability of ingested THC is only 4% to 12%, which sounds like it should be milder, but the liver converts THC into a more potent metabolite during digestion. The onset is slower (30 minutes to two hours), the peak comes later, and the whole experience can last four to eight hours or longer. If you ate too much of an edible, you’re in for a longer ride, but the intensity will gradually taper. Knowing this timeline can itself reduce anxiety, because the fear that “this will never end” is often the worst part.
Using CBD to Take the Edge Off
CBD works against THC at a molecular level. It binds to the same brain receptor THC targets, but instead of activating that receptor, it changes its shape so THC can’t bind as effectively. Scientists call this negative allosteric modulation, but what it means in practice is that CBD turns down the volume on THC’s effects.
If you’re currently too high, a CBD tincture or oil placed under the tongue will absorb faster than a gummy or capsule. Look for a product with little to no THC in it. The effects won’t be instant, but many people report feeling noticeably calmer within 15 to 30 minutes.
For future sessions, choosing products with a higher CBD-to-THC ratio is one of the most reliable ways to stay comfortable. A 1:1 ratio of CBD to THC provides noticeable effects while keeping intoxication more manageable. A 2:1 or 3:1 ratio further reduces the high while preserving therapeutic benefits. Many medical cannabis patients find that a 20:1 CBD-to-THC ratio provides symptom relief without feeling intoxicated at all. Experimenting with these ratios lets you dial in the experience you actually want.
Terpenes That Reduce Anxiety
Certain aromatic compounds found in plants, including cannabis itself, can meaningfully shift the quality of a high. Limonene, the compound responsible for the citrus smell in lemon peels, has been studied specifically alongside THC. In a clinical trial at Johns Hopkins, 15 mg of limonene significantly reduced anxiety, paranoia, and similar negative effects caused by a high dose of THC. Lower amounts of limonene had smaller effects, suggesting a dose-dependent relationship. Smelling or eating citrus fruit won’t deliver a precise dose, but anecdotally, many people find it helpful.
Alpha-pinene, found in pine needles and rosemary, works through a different mechanism. It inhibits an enzyme that breaks down a key memory-related chemical in the brain, essentially supporting the short-term memory and mental clarity that THC tends to impair. This is the same mechanism targeted by certain dementia medications. Smelling fresh rosemary or pine is a low-effort way to introduce pinene when you’re feeling foggy.
Preventing It Next Time
Most uncomfortably intense highs come from one of three mistakes: taking too much, consuming on an empty stomach, or not waiting long enough before redosing an edible. For inhaled cannabis, start with one small puff and wait ten minutes before taking another. For edibles, start with 2.5 to 5 mg of THC and wait at least two full hours before considering more. The slow onset of edibles is the number one reason people accidentally overconsume.
Your setting matters as much as your dose. Being in an unfamiliar place, around people you don’t fully trust, or in a situation where you need to perform (a party, a concert with strangers) amplifies the anxious side of THC. Consuming in a comfortable, low-pressure environment with people you like gives your brain fewer reasons to interpret the altered state as threatening.
Tolerance also plays a role. If you haven’t used cannabis in weeks or months, your receptors are fully sensitive and a dose that used to feel mild may now feel overwhelming. Treat any return after a break as if you’re starting fresh.
When It’s More Than Just Being Too High
An uncomfortable high is almost never dangerous, but there are physical signs that warrant medical attention. If you experience severe, repeated vomiting that you can’t stop, especially alongside abdominal pain, you may be dealing with a condition called cannabis hyperemesis syndrome. This typically occurs in people who have used cannabis frequently for over a year, and it involves intense cyclic vomiting episodes that only resolve with sustained abstinence. A hallmark sign is an unusual compulsion to take hot showers or baths for relief.
Dehydration from prolonged vomiting is the real risk. Dark or very little urine, sudden confusion, dizziness, fainting, rapid heartbeat, or rapid breathing all signal that your body needs more help than home remedies can provide. These symptoms call for emergency care.
