ABV Weed: What to Do With Already-Vaped Bud

🌿 What is ABV weed?

ABV stands for already-been-vaped (you'll also see it called AVB, already-vaped bud). It's the spent herb left in your chamber or dosing capsule after you've finished a session in a dry-herb vaporizer like the Mighty, Crafty or Venty. Instead of burning your flower, a vaporizer heats it just enough to release the good stuff as vapor, which leaves the plant material behind, lightly toasted rather than turned to ash.

Color is a rough guide. Fresh-off-the-vape herb usually ranges from light golden brown to deep chocolate brown, depending on how hot and how long you ran it. If it's black and crumbly like ash, that's combustion, not vaping, and there's little point saving it. Good ABV smells toasty and nutty, a bit like popcorn, not harsh or burnt.

💰 Why does ABV still have value?

A vaporizer is efficient, but it's not perfect. How much it leaves behind depends on the device, the temperature and how long you keep drawing. In a lab study that vaporized cannabis at 210 °C until it was spent, the Volcano left up to about 15% of the THC in the leftover herb, and the other vaporizers tested left less than 5% (Lanz et al., PLOS ONE, 2016). Home sessions that run cooler or stop early probably leave more, but nobody has measured typical home ABV, so its strength can range from next to nothing to surprisingly strong. That's why it's worth saving, and why every batch should be treated as unknown.

There's a bonus baked in, literally. Your vaporizer has already heated the herb, and heat converts the raw acid THCA into active THC, a step called decarboxylation. Lab work on the Volcano found this conversion rises with temperature but isn't always complete (Hazekamp et al., 2006), and nobody has measured how far it goes in typical ABV. Still, ABV has already had a heating step that fresh flower hasn't, so the recipes below skip the separate oven step and go straight into butter, oil or a pot.

Potency depends on your vape temperature

Not all ABV is created equal. The temperature you vaped at is one of the big factors, along with how long you vaped and which device you used. Lab tests show that more THC is released as the temperature goes up (Hazekamp et al., 2006), so if you run cool and short, more is likely to stay in the herb. Run hot and long, and more of it is already gone, so the leftovers are usually weaker and darker. Treat the table below as a rough direction, not a potency test.

🫙 Collecting & storing ABV

The trick to actually using ABV is collecting enough of it. A single session leaves barely a pinch, so you build up a stash over time. Keep it simple:

🍪 Turn ABV into edibles

Edibles are the simplest way to use ABV, because the herb has already been heated. One rule ties them together: cannabinoids dissolve in fat, not water, and clinical studies have found that taking cannabinoids with a high-fat meal raises how much the body absorbs (one example, on CBG). So pair ABV with something fatty rather than eating it dry. You have two routes.

Route 1: infuse a fat, then cook or bake with it

This is the most consistent route, because the dose spreads evenly through the fat. Warm your ABV in butter, coconut oil or olive oil and hold it on very low heat, well below a boil, for about 30 to 60 minutes, then strain out the plant material through cheesecloth. This is a common home method; there's no tested standard for ABV. Use a double boiler, a small saucepan on the lowest setting, or a slow cooker on low; add a splash of water so nothing scorches, do not let it boil, and skip the microwave. ABV has already been heated in the vape, so the goal here is only to pull what is left into the fat. Then put that infused fat to work:

• Baking: swap the recipe's butter or oil for your infused fat in brownies, cookies, banana bread or muffins.
• Savory cooking: stir it into pasta sauce, drizzle over pizza, whisk into a salad dressing, or finish roasted veg with it.
• Spreads: whip it into a compound butter, or blend infused oil into hummus or pesto.

Route 2: mix ABV straight into fatty foods (fast and lazy)

Because ABV has already been heated, you can stir it directly into strong, fatty foods and skip the cooking. The dose is less even than with an infused fat, but it takes 30 seconds. Lean on fat and bold flavors to carry it and hide the grassy taste:

• Peanut or nut butter: the classic. Fatty, thick, and the strong flavor masks ABV well.
• Chocolate: melt it (cocoa is full of fat), stir in ABV, then set it into bark or bites in the fridge.
• Nutella or chocolate spread: same idea with zero effort and a great flavor cover.
• Honey: honey has no fat on its own, so spread it on buttered toast, or use it in a firecracker below.
• Smoothies and shakes: blend ABV with full-fat milk, yogurt or a spoon of nut butter for the fat.
• Yogurt or ice cream: stir into full-fat yogurt or softened ice cream; the milk fat does the work.
• Energy balls: mix ABV into a no-bake ball of oats, nut butter and honey, then chill.
• Firecracker: the classic. Spread nut butter or Nutella on a cracker, sprinkle ABV, top with a second cracker. The fat carries it, no oven needed.

ABV tea (and why a quick mug steep falls short)

Straight talk: tea is likely the weakest way to use ABV. Cannabinoids dissolve in fat, not water. In a lab study of standard cannabis tea made from fresh flower, the tea held only a small fraction of the THC in the herb (Hazekamp et al., 2007), and another study found oil pulled out far more cannabinoids than water (Pacifici et al., 2017). A quick steep in a cooling mug, with a knob of fat floating on top, is unlikely to do better. If you want to try tea anyway, this version at least gives it a fair chance.

ABV tinctures & capsules

Want something that's easier to measure out and carry around? Here is how to make both.

ABV tincture

A tincture steeps ABV in strong alcohol so the cannabinoids move into the liquid. People often hold a few drops under the tongue, but some of it gets swallowed, so don't assume it will kick in fast; time it like an edible. Keep it sealed, cool and dark.

• Which alcohol: high-proof food-grade (drinkable) ethanol. Everclear or grain alcohol at about 95% (190 proof) is ideal, and higher proof works better because water dilutes the result. Get it at a liquor store, or at a pharmacy sold as potable ethanol. Never use isopropyl, rubbing, or denatured alcohol: those are toxic and are for cleaning only.
• How much: just enough alcohol to fully cover the ABV in a small sealed jar.
• How long: shake it daily and give it a week or two, then strain through a coffee filter. This is a home method; there's no tested best steeping time for ABV. To speed it up, sit the sealed jar in a warm-water bath for an hour or two, but keep it well away from any flame, since alcohol vapor is flammable.
• Alcohol-free option: food-grade vegetable glycerin also works, but cannabinoids dissolve less readily in it than in strong alcohol, so expect a milder, sweeter result.

ABV capsules

Infusing first gives you a more even result than stuffing loose ABV into a capsule, because whatever is left gets spread through the oil instead of sitting in random bits of plant matter. So do it in this order.

• Infuse first, then fill: gently warm your ABV in coconut or MCT oil (the same low simmer as the butter method), strain out the plant material, and fill the capsules with the strained, infused oil. That spreads what's there evenly through the oil, although the strength is still unknown.
• Start with one: the strength of a homemade batch is unknown, so try a single capsule, give it the full edible wait described above, and only adjust next time. Label the jar clearly.

😋 Dosing & taste: the honest bit

Two things trip people up with ABV. First, taste. ABV has a strong, grassy, toasted flavor that some people find rough. Bury it in chocolate, peanut butter, honey or heavily spiced dishes rather than anything delicate. Grinding it fine and mixing it well helps too.

Second, strength. There's no lab on your kitchen counter, so treat every new batch as an unknown. Some batches will be weak, and some, especially from low-temperature sessions, can be stronger than you expect. Always start small, wait the full time, and only change the amount next time, once you know how that batch behaves.
