ABV Cannabis Tincture Recipe: 5 Simple Steps with T-Check

This ABV cannabis tincture recipe shows you exactly how to extract the remaining THC from already been vaped weed using the quick wash ethanol (Q-wet) method. The results were surprisingly potent — 26.7 mg of THC per milliliter, totalling around 934 mg from just 10 grams of ABV. Don’t throw away your vape leftovers.

What Is ABV and Why Make an ABV Cannabis Tincture Recipe?

ABV stands for Already Been Vaped — the brown, toasted material left in your vaporizer after a session. Because vaping does not combust cannabis, a significant amount of THC and other cannabinoids remain in the ABV after use. An already been vaped tincture is one of the most efficient ways to recover those leftovers and turn them into a usable edible product.

5 Simple Steps for the ABV Cannabis Tincture Recipe

1. Weigh your ABV — Measure out approximately 10 grams of ABV into a clean mason jar. ABV is already partially decarboxylated from the heat of vaping, so no additional oven decarb step is required before making the tincture.
2. Add 190 proof alcohol and shake — Pour 70 mL of 190 proof alcohol tincture grade ethanol over the ABV in the mason jar. The higher the proof, the better the extraction — 190 proof is nearly pure ethanol and produces the most potent result. Seal the jar and shake vigorously for 10 minutes. This is the ABV quick wash ethanol (Q-wet) method: a fast extraction that pulls cannabinoids efficiently without over-extracting chlorophyll.
3. Strain and press the material — Pour the mixture through a fine mesh strainer into a clean container. Use the back of a spoon to press down on the ABV pulp and extract as much liquid as possible. The resulting tincture will be deep green from chlorophyll — this is normal. Set the spent ABV pulp aside on parchment paper in case some residual potency remains.
4. Check if dilution is needed before testing — The T-Check potency tester measures up to 15 mg/mL without dilution. If your first test reads “outside measured range,” dilute: mix 1 mL of tincture with 0.5 mL of clean alcohol (3:1 ratio) and test the diluted sample. Multiply the result by 3 to get the true concentration.
5. Run the T-Check tincture potency test — Use “decarb flower infusion” mode in the T-Check app. Record room temperature, load 4–5 drops of filtered tincture onto the tray, and run the test. In this experiment the T-Check tincture potency test showed 8.9 mg/mL in the diluted sample — multiplied by 3 equals 26.7 mg/mL in the final tincture. With 35 mL recovered, total potency was approximately 934 mg THC.

How Potent Is ABV Tincture?

More potent than you might expect. This ABV cannabis tincture recipe using 10g of ABV from 20% THC weed yielded an already been vaped tincture at 26.7 mg/mL — high enough for therapeutic doses. The theoretical maximum from unvaped 20% weed would have been around 19 mg/mL in 70 mL, suggesting the ABV retained significant potency, possibly because some vaped hash was mixed in with the flower.
