Cannabis distillate syringe potency: the short answer

Distillate syringes sold in the US test between 80% and 95% THC by weight. A 1 gram syringe at 85% THC holds about 850 mg of THC. A 0.5 gram syringe at the same percent holds about 425 mg. The percent on the label is total THC after decarboxylation. A licensed lab measures it on one batch.

Convert percent to milligrams

Net weight in milligrams times THC percent equals THC milligrams.

  1. 1 g = 1000 mg.
  2. 85% = 0.85.
  3. 1000 x 0.85 = 850 mg THC.

A 0.5 g syringe at 92% holds 460 mg. A 1 g syringe at 78% holds 780 mg. The spread across one shelf can reach 120 mg per gram or more.

What lowers the number

Distillate tests high in THC because the process strips plant material, terpenes, and other cannabinoids. Raw distillate can reach 95%. Oil blended for vape carts lands lower once a cut is added.

Label accuracy and state variance

State agencies set a variance window between the label and a retest. Limits differ by state. A syringe labeled 85% can pass a retest at 80% in one state and fail in another. One syringe is a small sample drawn from a large batch, so batch-to-batch spread is normal. Ask for the batch test report when the package does not print the figures.

Storage and handling

Keep the syringe capped and upright at room temperature, away from light. Warm the barrel under running warm water if the oil clogs. Do not use a flame. THC converts to CBN with heat and oxygen exposure over months.
