A cannabis high will always pass on its own, but there are several things you can do right now to take the edge off and feel more in control. Whether you smoked too much or an edible hit harder than expected, the strategies below can shorten the experience or make it significantly more manageable.
Know Your Timeline
The single most useful thing to know is how long this will last. If you smoked or vaped, the effects peak almost immediately and typically last one to three hours, though mild lingering effects can stretch to eight hours. If you ate an edible, the timeline is very different: THC levels in your blood don’t peak until two to three hours after ingestion, and effects can take more than six hours to fully fade. This means if you ate something 45 minutes ago and feel overwhelmingly high, you may still be on the way up. That’s uncomfortable to hear, but knowing it helps you plan rather than panic.
Whatever your method, remind yourself: this is temporary. No one has ever died from a cannabis overdose alone. Your body is already processing the THC out of your system.
Try Citrus
This one has real science behind it. A Johns Hopkins study found that d-limonene, the compound that gives lemons, limes, and oranges their citrus smell, significantly reduced feelings of anxiety and paranoia caused by THC. In the study, 20 healthy adults inhaled vaporized limonene alongside THC, and the more limonene they received, the greater the anxiety reduction. Importantly, limonene didn’t dull the other effects of THC or produce any side effects of its own.
You probably don’t have vaporized limonene at home, but you do have options. Sniff or zest a lemon, squeeze fresh lemon juice into water, or chew on a piece of lemon peel. Orange peel works too. The research tested inhalation rather than ingestion, so getting the scent into your nose is a good starting point. It won’t end your high, but it may meaningfully calm the anxiety component.
Use CBD If You Have It
CBD works against THC at the receptor level. THC activates the brain’s CB1 receptors, which is what produces the high. CBD does the opposite: it acts as an indirect antagonist at those same receptors, essentially making it harder for THC to fully activate them. If you have CBD oil, a CBD tincture, or even a high-CBD flower, using it can blunt the intensity of your experience. This won’t be instant, but many people report a noticeable softening within 15 to 30 minutes.
Ground Yourself With Your Senses
When a high turns uncomfortable, your mind can spiral. Grounding techniques pull your attention back to the physical world around you and interrupt that loop. The most widely recommended exercise is the 5-4-3-2-1 method:
- 5 things you can see
- 4 things you can touch or feel
- 3 things you can hear
- 2 things you can smell
- 1 slow, deep breath
Go through each one deliberately. Name them out loud if you can. This works because it forces your brain to process real sensory input instead of recycling anxious thoughts.
Breathe Slowly and Deliberately
Cannabis can raise your heart rate, which your brain interprets as a sign of danger, which creates more anxiety, which raises your heart rate further. Slow breathing breaks that cycle. Inhale through your nose for four counts, hold for four counts, exhale through your mouth for six to eight counts. The longer exhale is what activates your body’s calming response. Do this for two to three minutes and you should feel your heart rate start to settle.
Progressive muscle relaxation pairs well with breathing. Starting at your feet, tense each muscle group for five seconds, then release. Work your way up through your calves, thighs, stomach, hands, shoulders, and face. The physical release of tension signals safety to your nervous system.
Change Your Environment
Sometimes the simplest intervention is the most effective. Move to a different room. Step outside for fresh air. Turn off whatever you’re watching if it’s adding to your unease. Put on familiar, calming music. Take a warm shower. The goal is to give your brain new, non-threatening stimuli to process. If you’re at a party or social gathering and feeling overwhelmed, removing yourself to a quieter space can make a dramatic difference.
Eat and Drink Something
Drinking cold water gives you something physical to focus on and helps with the dry mouth that THC commonly causes. Some people find that eating a meal or snack helps them feel more grounded and normal. There’s a long-standing folk remedy around chewing black peppercorns, which contain a terpene called beta-caryophyllene that interacts with cannabinoid receptors. The evidence for this is mostly anecdotal, but sniffing or chewing on a few peppercorns is low-risk and worth trying if you have them handy.
Pine nuts are another commonly suggested food, as they contain alpha-pinene, a compound thought to promote mental clarity. Again, the direct evidence is limited, but eating something familiar and comforting helps regardless of the specific food.
What Not to Do
Don’t drink alcohol. It increases THC blood levels and will almost certainly make you feel worse. Don’t take more cannabis hoping a different strain will “balance things out” unless it’s a verified high-CBD product. Don’t drive. Don’t fight the feeling by trying to act completely sober in a high-pressure social situation. Give yourself permission to sit this one out.
When It’s More Than Discomfort
A standard cannabis high, even an intense one, resolves on its own. But certain symptoms cross into territory that warrants medical attention: persistent confusion or an inability to recognize where you are, multiple seizures, a heart rate that stays dangerously fast for an extended period, or significant difficulty staying conscious. These are rare with regular cannabis but more common with synthetic cannabinoids (sometimes sold as “spice” or “K2”), which can cause severe agitation, seizures, and rapid heart rate. If you or someone near you consumed a product and the reaction seems extreme or unfamiliar, calling for help is the right move.
For the vast majority of people reading this, though, the situation is manageable. Breathe, find a lemon, change your setting, and let time do its work. You will feel normal again.
