Decarbing Weed in an Instant Pot: The Viral Method That Actually Works

So you saw the same viral TikTok I did, and you’re deep into “how to decarb weed in Instant Pot” searches. 

@gulfofaisha_ posted a video saying she “might never smoke again” after decarbing her weed in an Instant Pot, brewing the leftover water as tea, and using the same setup to make edibles. Absolute genius, and the comments agreed. Once you try decarbing weed in an Instant Pot, going back to the oven feels like a downgrade.

Three reasons this method is taking over. First, the smell stays almost completely contained. The mason jar holds it in until you decide to open the lid. Second, the temperature is more consistent than your oven, which probably runs 25-50°F off from whatever you set it to. Third, you can decarb and infuse in the same pot. No extra mess.

This guide walks through the entire process. The science of why the Instant Pot works (briefly—you don’t need a chemistry lecture). An honest comparison to oven decarb. The full step-by-step decarboxylation method. A weed butter recipe using the same equipment. The cannabis tea angle from the original TikTok. Plus tips, troubleshooting, and storage that come from people actually doing it.

Cannabinoids in raw cannabis exist as “acidic precursors,” and they don’t have any psychoactive weight until heated. Compounds like THCA, CBDA, and CBGA are then converted to their active forms (THC, CBD, and CBG) through a process called decarboxylation. The standard target for THC is 240°F for 40 minutes. Hit that consistently, and you get full potency. Miss it in either direction, and you lose product.

Here’s where the oven method falls apart for most home cooks. Most home ovens run 25-50°F off from the dial setting. You set it to 240°F, but you may be cooking at 280°F. At that temperature, you’re starting to degrade THC into CBN (the sleepy cannabinoid). You’re also burning off the terpenes that make different strains feel different.

The Instant Pot on High Pressure automatically reaches a stable 240-245°F. The pressure environment regulates the temperature in a way that an open oven cavity simply doesn’t. You’re not relying on a thermostat that may or may not be calibrated. You’re relying on physics. Water under pressure boils at a specific temperature, and that temperature happens to land almost exactly on the THC decarb target.

Then there’s the smell. Oven decarb fills the kitchen with weed smell and lingers in the curtains for the rest of the day. Instant Pot decarb in a mason jar produces almost no detectable odor until you open the jar. At which point you can step outside, open a window, or do whatever works for your situation. For anyone making edibles in any situation where discretion matters, the smell difference alone is worth the switch.

One honest limitation worth flagging: the Instant Pot’s High Pressure temperature is slightly too low for ideal CBD decarboxylation. That cannabinoid actually prefers higher heat or longer time. If you’re working with a high-CBD strain or pure hemp flower, extend the cook time or end it with a brief oven finish.

For THC and CBG decarb, the Instant Pot is nearly perfect.

This is the active 40-minute pressure method—the standard guide on how to decarb weed in an Instant Pot for THC-focused edibles. There’s a longer 12-hour version (more on that in the cannabis tea section). But the high-pressure 40-minute approach is the fastest way to do it.

• An Instant Pot (any model with a High Pressure setting)
• Mason jar(s) with lid, pint or smaller works best
• Steamer rack insert (most Instant Pots come with one)
• 2 cups water
• Canning tongs or oven mitt
• Ground or crumbled cannabis

1. Grind or crumble your cannabis to roughly barley-size pieces. Not powder. Consistent size means consistent heat distribution. A coffee grinder works, but pulse it. Don’t run it continuously. You want it broken up.
2. Fill your mason jar with the cannabis and screw the lid on finger-tight. Not fully cranked. A slightly loose lid lets minor pressure equalize without letting the cannabinoids escape. This is the same principle as canning. You want a seal, not a vacuum.
3. Place the steamer rack inside the Instant Pot, pour in 2 cups of water, and rest the mason jar on the rack. Never directly on the bottom of the pot. The water creates steam. The jar cooks from the surrounding heat, not from being submerged.
4. Lock the Instant Pot lid and set the pressure valve to SEALING. Standard pressure-cooking position.
5. Set to High Pressure for 40 minutes. Turn the “Keep Warm” feature OFF. This part matters. If Keep Warm is on, the pot keeps cooking your cannabis after the timer ends, and you can over-decarb. Switch it off before you start.
6. Let the Instant Pot do its thing. It’ll build pressure for 5-10 minutes, then run the 40-minute cycle at temperature. Total active time from start to finish is roughly 45-55 minutes. You don’t need to babysit it.
7. When the cycle finishes, do a Quick Release. Open the pressure valve carefully—steam comes out fast and hot. Stand to the side, not directly over it.
8. Use tongs or an oven mitt to remove the mason jar. Important: do not place the hot jar directly on a cold counter or sink. Sudden temperature change cracks glass. Put it on a wooden cutting board or a folded towel.
9. Leave the lid closed and let the jar cool for at least 30 minutes before opening. This lets the residual heat finish any decarboxylation and lets the pressure inside the jar equalize.
10. Open and inspect. Successful decarb looks olive, golden-brown, or light brown. The smell should be toasty and slightly nutty. Bright green color means it’s underdecarbed (run another 15-20 minutes). Very dark brown or scorched smell means it overheated.

40 minutes on High Pressure, plus about 10-15 minutes for the pot to reach pressure, plus 30 minutes of cooling. So you’re looking at roughly 90 minutes, with maybe 10 minutes of actual hands-on work.

If you’re following the TikTok method that uses a 12-hour cook, that’s a different approach. It typically runs on Low Pressure or the Slow Cook setting over a long period. You’ll have usable THC water as a byproduct, but it’s not the most efficient way to decarb weed.

The reason the Instant Pot is genuinely the best tool for home edibles isn’t just the decarb step. It’s that you can roll straight from decarbing weed in an Instant Pot into an infusion without changing equipment. Making weed butter in an Instant Pot is also faster and cleaner than the basic stovetop method. 

Here’s the full Instant Pot weed butter recipe:

• Decarbed cannabis from the step above (still in the mason jar)
• 1 cup unsalted butter per 1/2 ounce of cannabis (adjust ratio up or down based on desired potency)
• Cheesecloth
• A bowl or container for straining

1. Once your decarbed cannabis has cooled to a manageable temperature, add the butter directly to the mason jar. No transfer needed. The same jar that decarbed your weed is now your infusion vessel.
2. Return the jar (loosely lidded again) to the Instant Pot on the steamer rack. Keep the 2 cups of water in the pot. You’re using the same setup as decarb, just changing the cooking method.
3. Set the Instant Pot to Slow Cook on Low for 2-3 hours, or use the Keep Warm setting for up to 4 hours. These settings hold the temperature around 185-190°F. Warm enough to fully infuse cannabinoids into the butter without degrading them. Don’t pressure-cook this step. High pressure burns off the terpenes that give your butter its flavor and effect character.
4. When infusion is done, carefully remove the jar. Let it cool slightly so you can handle it without burning yourself.
5. Strain through cheesecloth over a bowl. Squeeze the cloth firmly to press out as much butter as possible. The butter retained in the plant material is where a meaningful percentage of the potency is. Squeeze it out.
6. Pour the strained butter into a storage container and refrigerate. As it cools, the butter will firm, and any residual water will separate to the bottom. Once solidified, pour off or discard the water layer. You’re left with clean cannabutter ready to use.
7. Store in an airtight container in the refrigerator (keeps 2-3 weeks) or freezer (keeps 3-6 months).

Potency per tablespoon depends on the strength of your weed and the THC percentage.

If you used 3.5 grams of 20% THC flower, that’s approximately 700mg total THC in the batch. Spread across 16 tablespoons of butter (one cup), you’re looking at roughly 44mg per tablespoon.

Here’s where @gulfofaisha_’s original TikTok video gets interesting. The 12-hour cook time was specifically extracting cannabinoids and water-soluble compounds into the cooking water itself. Then, she uses it for tea.

While it sounds great on paper and genuinely seems to work, THC is not highly water-soluble. You’re not pulling out the bulk of the potency this way. Most of the THC stays in the plant material. But over an extended cook, the water picks up enough cannabinoids and terpenes to produce noticeable effects.

1. After the full decarb or extended cook cycle, carefully pour the water out of the Instant Pot. This is the water surrounding the mason jar, not the contents of the jar. Use the pot’s pour spout if it has one.
2. Strain through cheesecloth or a fine-mesh strainer. Removes any sediment.
3. Add to a mug. Then add a fat source. A splash of whole milk, a pat of butter, a small amount of coconut oil. THC binds to fat, which may help improve its absorption. 
4. Sweeten if you want, and drink. Expect a slower onset than smoking (typically 30-90 minutes) and effects that last longer than inhaled cannabis.

Don’t throw it out. After you’ve extracted the tea water, the plant material still has plenty of active cannabinoids. Strain the herb out, treat it as decarbed material. Then, use it for your weed butter recipe, Instant Pot infusion, or any other edible application. The tea is a bonus byproduct. The main potency is still in the flower.

• Don’t skip the steamer rack. The jar needs to sit above the water, not in it. Steam cooks the jar from outside. Submerging it doesn’t help and risks cracking the glass.
• Finger-tight lid only. Fully sealing the jar creates a real risk of pressure buildup inside the jar itself.
• Use Quick Release. You want to stop the heat the moment 40 minutes ends. Natural Release lets the pot keep cooking your cannabis at a slow declining temperature, which can over-decarb.
• Multiple jars work fine. As long as they fit on the steamer rack and the lid still closes, you can run two or three jars at once. Cook time stays the same.
• Same method for kief. Same time, same temperature. For concentrates like hash or rosin, use a smaller container and check at 30 minutes. Concentrates can over-decarb faster than flower.

• Cannabis looks green and barely toasted. Underdecarbed. Run another 15-20 minutes on High Pressure. Common cause: the Instant Pot took longer than usual to reach pressure.
• Cannabis is dark brown or smells burnt. Slightly overheated. Most often caused by Keep Warm being on after the cycle, which keeps adding heat. The cannabis is still usable, but expect more sedating effects (some THC has likely converted to CBN).
• Jar cracked. Sudden temperature change. Always remove the jar onto a wooden surface or onto a cloth. Never directly onto cold countertops or into the sink.
• No smell at all when you open the jar. Could be normal (the seal preserves aroma) or could indicate underdecarb. Check the color. If it’s still bright green, run another cycle. If it’s olive or golden-brown, you’re good. The smell sometimes develops more once the cannabis cools and breathes.

Once you’ve gone through the full process of decarbing weed instant pot style and infusing your cannabutter, storing determines how long the potency holds.

Decarbed cannabis:

• Airtight container, cool dark location (drawer, cabinet, pantry)
• Not the refrigerator—moisture and temperature fluctuation degrade potency
• Properly stored, decarbed cannabis lasts 6 months to a year
• Label with the date and the strain if you can

Cannabutter:

• Airtight container in the refrigerator: 2-3 weeks
• Freezer (portion in ice cube trays first for easy dosing): 3-6 months
• Label clearly with the potency estimate and the date—cannabutter looks identical to regular butter
• Always store away from children and any adult who hasn’t consented to consuming cannabis
