What is AVB? If you’ve been dry herb vaping and throwing away the spent material at the end of each session, you’ve been throwing away something valuable. AVB — Already Vaped Bud (also called ABV, Already Been Vaped) — is the cannabis left over after vaporizing, and it’s still worth using. In this guide, we’ll explain what is AVB, why it’s already decarboxylated, and cover 5 amazing ways to put it to work.
What Is AVB? The Basics Explained
What is AVB, exactly? It’s the byproduct of dry herb vaping. When you load cannabis into a vaporizer, heat it up, and take your hits, the material inside gets partially decarboxylated as part of the vaporization process. Once the session is over and you empty out the chamber, what remains is AVB — darkened, spent herb that still contains residual cannabinoids.
There are two common abbreviations: AVB (Already Vaped Bud) and ABV (Already Been Vaped). They mean exactly the same thing — both refer to the material left over after a vape session. You’ll see both used interchangeably in the cannabis community.
The most important thing to understand about what is AVB: it is already decarboxylated. You do not need to decarb it again before using it in edibles. You can eat it directly (though the taste is not great) or use it in a recipe without any extra preparation step.
What Is AVB Good For? 5 Amazing Uses
1. Cannabutter and Canna-Oil
The most popular use for what is AVB — making infused butter or oil. Since AVB is already decarboxylated, the infusion process is the same as using regular decarbed flower, just with lower and less predictable potency. You can use it to make cannabutter for baking, canna-coconut oil, or any fat-based infusion. The POT by Noids is perfect for small-batch AVB infusions.
2. Cannabis Tincture
What is AVB’s potential as a tincture? Significant. Soak your AVB in high-proof alcohol (like Everclear) for several weeks, then strain and bottle it. The resulting Green Dragon tincture can be used sublingually or added to food and drinks. It’s a zero-waste way to extract every last bit of value from your vaped material.
3. Firecrackers (No Cooking Required)
Firecrackers are the simplest AVB edible. Spread peanut butter or Nutella on a cracker, sprinkle AVB on top, sandwich it with another cracker, wrap it in foil, and optionally bake at low heat for 20 minutes. You can even eat them at room temperature since what is AVB already comes pre-decarboxylated. The fat in the peanut butter helps bind the cannabinoids for absorption.
4. Salves and Topicals
What is AVB useful for beyond getting high? Topicals. Infuse AVB into a carrier oil (coconut, olive, or jojoba oil), strain it, and mix with beeswax to create a salve. Cannabis topicals may help with localized discomfort and inflammation without a psychoactive effect since cannabinoids don’t significantly cross the skin barrier into the bloodstream.
5. Direct Consumption in Food
What is AVB doing in your peanut butter sandwich? Working! You can stir AVB directly into foods with fat — yogurt, peanut butter, hummus, even hamburger meat. The catch is the taste: AVB has a strong, earthy, somewhat unpleasant flavor. If you’re mixing it into food directly, a water cure (cold wash) first removes much of the funky taste without significantly affecting potency.
Does the Vaporizer Matter for AVB Quality?
Yes — significantly. Understanding what is AVB also means understanding that not all AVB is equal. How much residual THC your AVB contains depends on how efficient your vaporizer is:
- Dark brown or black AVB: Your vaporizer is highly efficient — it extracted most of the cannabinoids. Less residual THC remains, but the material is still useful.
- Light golden or yellowish-brown AVB: Less efficient extraction — more THC was left behind. This AVB is more potent and better for edibles.
- Partially used sessions: If you cut a session short before finishing the bowl, the AVB from that session is significantly more potent than a fully extracted session.
Works with any cannabis type — Delta 9, Delta 8, or CBD flower. All of them produce usable AVB since the vaporization process never extracts everything.
What Is AVB Water Cure?
A water cure (cold wash) involves soaking your AVB in cold water for 24–72 hours, changing the water every 8–12 hours. This removes water-soluble compounds that cause AVB’s harsh, bitter taste — while preserving the cannabinoids (which are not water-soluble). After the wash, dry your AVB thoroughly before use. The result is much milder-tasting material that’s easier to incorporate into food.
Frequently Asked Questions
What is AVB and do I need to decarb it?
AVB (Already Vaped Bud) is the spent cannabis material from dry herb vaping. It is already decarboxylated by the vaporization process, so you do not need to decarb it again before using it in edibles or tinctures. This makes what is AVB one of the most convenient cannabis materials to work with.
How potent is AVB?
Potency varies depending on your vaporizer’s efficiency, session length, and temperature settings. Light-colored AVB tends to be more potent (less THC was extracted), while dark AVB is less potent. Start with a small dose when trying any new AVB batch and wait at least 1–2 hours before consuming more.
Can you smoke AVB?
Technically yes, though it’s not pleasant. AVB smoked on its own produces harsh, unpleasant smoke. Mixing it 50/50 with fresh cannabis makes it more tolerable. Using AVB in edibles, tinctures, or topicals is a much better use of the material.
Does AVB work with CBD or Delta 8 cannabis?
Yes — what is AVB applies to all cannabis types. Delta 9, Delta 8, and CBD flower all produce usable AVB because vaporization never extracts all the cannabinoids present. The resulting AVB from any of these will retain residual cannabinoids worth using.
