The Lazy Person's Guide to AVB: What to Do With Your Vaporizer Leftovers

The Jar of Brown Stuff Under My Desk

For my first six months of vaping, I threw away my AVB. Every session, I'd tap out the brown, toasted remains of my bowl, dump it in the bin, and move on. Hundreds of sessions. Probably 50 grams of material. Straight into the rubbish. I was thirty-four, newly off the spliffs after nearly two decades, and convinced that I now understood cannabis. I did not.

Then Dave mentioned, casually, that he'd been saving his.

I didn't believe him. The stuff looked spent. Cooked. Done. How could roasted leftovers still do anything? But Dave's never steered me wrong on cannabis matters, so I started saving mine. Within a month, I had a jar. Within two months, I had enough to experiment. Within three months, I'd accidentally got so high from a peanut butter sandwich that I had to lie down for four hours and seriously reconsider my life choices.

AVB works. Properly. Throughout this entire Vaporizer 101 series, I've been telling you that your "waste is still active" without ever explaining what to actually do with it. This is that explanation. The lazy person's guide — minimum effort methods that actually work, plus the dosage warnings I wish someone had given me before that sandwich incident.

Why AVB Works (The 30-Second Science)

When you vape cannabis, you're heating it to temperatures between roughly 170–220°C. This does two things: releases cannabinoids into vapour (the stuff you inhale), and decarboxylates the remaining material (converts THCA into THC). That second part is why AVB works for edibles.

Raw cannabis contains THCA, which isn't psychoactive when eaten. To make it orally active, you need to apply heat — a process called decarboxylation that happens around 105–130°C. Your vaporizer does this automatically. By the time you've finished a session, the leftover material has been heated enough to convert most of the THCA into THC. It's "pre-activated" and ready to eat.

(Full science in What Actually Happens Inside Your Vaporizer. Vaping temperature affects AVB strength — The Temperature Guide covers this.)

The potency question:

AVB Colour	What It Means	Approx. Retained THC
Light golden / tan	Low temps, short sessions	6–10% — strongest
Medium brown	Moderate extraction	3–6% — middle ground
Dark brown / nearly black	High temps, long sessions	1–3% — weakest

One study on Volcano leftovers found that even after thorough extraction, the AVB retained about 9% THC — roughly 48% of the original content still sitting in the "waste."

Your bin has been eating your edibles.

Method 1: Just Eat It (Zero Effort)

Effort level: none. Taste: absolutely horrible. Effectiveness: works, but not optimal.

Yes, you can literally just eat AVB. Sprinkle it on yoghurt. Mix it into a smoothie. Dump it on toast. It will work. The THC is already activated. Your digestive system will process it. Effects will happen.

The problems: it tastes like roasted dirt mixed with burnt popcorn, the texture is dry and fibrous, and swallowing plant fibre can upset some stomachs.

Method 2: Firecrackers (Minimal Effort, Actually Enjoyable)

Effort level: 15 minutes including oven time. Taste: surprisingly decent. Effectiveness: excellent.

This is the classic lazy AVB method, and it's where I'd recommend most people start.

The Basic Firecracker Recipe

You need: crackers (digestive biscuits, graham crackers, Rich Tea — anything sturdy); high-fat spread (peanut butter, Nutella, almond butter — at least 30% fat); your AVB; tin foil.

Steps:

1. Spread a thick layer of peanut butter (or Nutella) on a cracker
2. Sprinkle your AVB dose onto the spread
3. Mix it in slightly with a knife or spoon
4. Top with another cracker (optional but neater)
5. Wrap tightly in tin foil
6. Bake at 150°C for about 15–20 minutes
7. Let it cool slightly, then eat

Why bother with the oven if AVB is already decarbed? The oven step isn't for activation — that's already done. It's for melting the fat and helping it absorb the cannabinoids, integrating the flavours so it tastes less like burnt weed, and slightly improving bioavailability.

The ultra-lazy version: skip the oven entirely. Mix AVB into peanut butter, spread on a cracker, eat. It works. It just won't absorb quite as efficiently and will taste slightly more "weedy."

Taste tips: Nutella hides the flavour better than plain peanut butter; crunchy peanut butter masks the texture better than smooth; a drizzle of honey helps; washing it down with milk or coffee helps more.

Method 3: Capsules (No Taste, Maximum Convenience)

Effort level: 20–30 minutes to make a batch. Taste: none (it's in a capsule). Effectiveness: good, slightly slower onset.

If you hate the taste of AVB in any form, capsules are your answer.

Basic AVB Capsules

You need: empty gel capsules (size 0 or 00, available from Amazon or health food shops); your AVB; a small spoon or capsule filling tray.

Steps: grind your AVB finer if it's chunky (optional but helps packing); open a capsule; pack AVB into the larger half; close the capsule; repeat until you've used your AVB.

Capsule Size	Holds Roughly
Size 0	0.4–0.5g of AVB
Size 00	0.6–0.8g of AVB

The upgraded version (better absorption): mix your AVB with warm coconut oil first, then fill capsules with the oil mixture instead of dry AVB. This improves absorption (fat helps), reduces plant fibre (less stomach upset), and makes capsules easier to swallow. Roughly 1g AVB per 1–2g coconut oil. Warm gently until mixed, let cool slightly, fill capsules before it solidifies.

Method 4: Simple Infusions (Moderate Effort, Best Results)

Effort level: 2–4 hours (mostly passive). Taste: can be quite good if done right. Effectiveness: excellent, most versatile.

If you're saving significant amounts of AVB and want to use it in cooking, infusing into oil or butter is the way to go.

How to Make It

You need: AVB (any amount — scale the fat accordingly); your fat of choice — coconut oil (best absorption), butter (best for baking), or olive oil (works but weaker); a jar and a pot of water (double boiler method).

Steps:

1. Combine AVB and your chosen fat in a mason jar (roughly 1:1 to 1:2 ratio by weight)
2. Place the jar in a pot with a few inches of water
3. Heat the water to a gentle simmer (not boiling)
4. Let it infuse for 2–3 hours, stirring occasionally
5. Strain through cheesecloth or a fine sieve (optional — leave the plant material in for maximum potency)
6. Let cool and store

If using butter: add equal parts water when simmering. The water prevents burning and washes away bitter compounds. After straining, refrigerate — the butter solidifies on top, water underneath. Separate and discard the water.

Ratio: start with roughly 7–14g AVB per 100g of fat. Adjust based on your AVB colour and desired strength.

Straining: optional. Removes plant material for cleaner taste and texture, but you lose a tiny bit of potency. For brownies, strain. For "I just want it to work," leave it in.

Method 5: Water Curing (For the Taste-Sensitive)

If you're making larger batches of butter or oil and the taste bothers you, water curing your AVB first makes a significant difference.

Why it works: THC and other cannabinoids are fat-soluble, not water-soluble. The compounds that make AVB taste terrible (tannins, chlorophyll residue, bitter plant compounds) are mostly water-soluble. Soaking AVB in water washes away the bad-tasting stuff while leaving the good stuff behind.

How to Water Cure

1. Put your AVB in a jar or wrap in cheesecloth
2. Cover completely with room temperature water
3. Let it sit for several hours
4. Drain, refill with fresh water
5. Repeat every 12–24 hours for 2–4 days
6. When the water runs mostly clear, you're done
7. Dry thoroughly before storage or use (low oven at ~100°C for an hour, or air dry for a day)

The shortcut: rinse AVB in a fine sieve under warm tap water until the water runs clearer, then dry in a low oven. Faster but slightly less effective.

Is it worth it? For firecrackers or capsules, probably not — the peanut butter or capsule shell hides the taste anyway. For butter/oil for baking, yes. For cooking with the oil directly, definitely yes.

The Dosage Warning (Read This Before You Do Anything)

Here's where I tell you about the peanut butter sandwich incident.

I'd been vaping at relatively low temperatures — 175–185°C mostly, for flavour. My AVB was light golden brown. I figured "it's leftovers, it's weak, I'll use plenty." I made a firecracker with about 1.5 grams of AVB. Ate it at 7 p.m. By 7:45, nothing. By 8:30, still nothing. I considered making another one.

At 9:15, it hit. Hard. Much harder than expected.

Why AVB Edibles Can Surprise You

• Unpredictable potency: AVB strength varies based on vaping temperature, session length, starting material, and how light/dark it looks. There's no reliable way to know exact potency without lab testing.
• Light AVB is stronger than you think: if you vape at low temps and stop early, your AVB might retain 6–10% THC. That's not "weak leftovers" — that's significant.
• Edible onset is slow: unlike vaping (effects in minutes), edibles take 45–120 minutes to kick in. The temptation to redose before it hits is strong. Resist it.
• Edibles hit harder: when you eat THC, your liver converts it to 11-hydroxy-THC, which crosses the blood-brain barrier more effectively. Edible highs feel different — often stronger and longer-lasting than inhaled cannabis.
• Duration is long: AVB edibles can last 4–8 hours. If you overdo it at 8 p.m., you're in for a long night.

Starting Dose Guidelines

AVB Colour	Starting Dose
Light tan AVB	0.25–0.3g
Medium brown AVB	0.5g
Dark brown AVB	Can probably handle 1g+, but still start lower

Wait time: full 2–3 hours before considering more. The practical rule: treat 1g of decent AVB roughly like 0.2–0.3g of fresh flower for edible purposes. Then adjust based on your experience.

What If You Take Too Much?

It happens. Here's what "greening out" feels like and what to do.

Symptoms: intense anxiety or paranoia; racing heart; nausea or dizziness; sweating; feeling "out of control"; time distortion (minutes feel like hours).

What to do: find somewhere comfortable; lie down, dim the lights, put on something familiar and soothing; hydrate (water, not alcohol); try CBD if you have it (CBD can moderate THC's effects for some people); chew black peppercorns if you're game (the terpenes may help); wait it out (the peak will pass in 2–4 hours); sleep if you can.

Start low. Wait long. You can always take more next time. You can't un-eat what you've already eaten.

Stomach Issues (The Fibre Problem)

AVB is plant material. If you're eating significant amounts of it — especially dry, in capsules, or unfiltered in butter — you're consuming a lot of plant fibre. Common complaints: bloating, gas, stomach cramps, diarrhoea (especially with large doses).

Solutions: use strained oils/butters instead of whole plant material; take smaller doses spread throughout an evening rather than one big dose; always eat AVB with a proper meal, not on an empty stomach; if capsules upset your stomach, switch to infused oil or firecrackers.

Those with IBS, Crohn's, or other inflammatory bowel conditions may want to stick to filtered infusions rather than consuming the plant material directly.

Storage

You're probably accumulating AVB gradually over time. Here's how to store it:

• Container: airtight jar (mason jar is perfect)
• Location: cool, dark, dry place
• Viability: months to years if stored properly

The enemies: moisture (can cause mould, especially if AVB isn't fully dry); light (degrades cannabinoids over time); air (oxidation slowly converts THC to CBN — more sedating, less psychoactive); heat (accelerates degradation).

Can you mix batches? Absolutely. Most people dump AVB from every session into the same jar, mixing strains and temperatures. This averages out the potency and works fine. Just accept that your jar is "mystery strength" and dose accordingly.

The Decision Tree

Not sure which method to use?

You Want…	Method
"I want to try this once to see if it works"	Make a single firecracker. 15 minutes of effort, decent taste, proper results.
"I hate the taste of weed"	Capsules. Zero taste, maximum convenience.
"I'm saving up a large amount and want to use it efficiently"	Make infused coconut oil or butter. Water cure first if taste matters.
"I cannot be bothered with any preparation"	Mix into peanut butter, eat with a spoon. Disgusting but it works.
"I want precise dosing"	Capsules with consistent infused oil in each. Closest you'll get to predictable strength.

What I Actually Do

I save all my AVB in a mason jar in the fridge. When the jar gets respectably full — usually every 2–3 months — I make a batch of coconut oil capsules. I warm coconut oil, mix in the AVB at roughly 1:1.5 ratio, let it infuse for a couple hours while I do other things, then fill size 00 capsules. Usually makes 20–30 capsules depending on how much I've accumulated.

They live in a jar in my desk. When I want an edible evening — usually weekends, when I don't have to function the next morning — I take 1–2 capsules with dinner. Effects kick in around 90 minutes later. Lasts the evening.

It's free. It's easy. It's using material I was literally throwing in the bin for six months like an idiot.

Your vaporizer just became an edibles machine. You're welcome.
