Edible Label Decoder: What “mg per serving” actually means
Labels for edibles list Delta-9 THC in milligrams for a single serving. That serving might be one piece, half a piece, or a measured amount (e.g., 1 capful or 1 gummy).
- Gummies example: “10 mg per serving” could mean one 10 mg gummy or ½ gummy if the piece is 20 mg.
- Drinks example: A 12 oz can might list 10 mg per serving and 1 serving per container, or 2 servings of 5 mg each.
Quick rule: Always confirm what the brand defines as one serving before you dose.
Total mg per package
Your label should also show servings per package. Multiply:
mg per serving × servings per package = total mg in the package
- Example: 10 mg per serving × 10 servings = 100 mg total
- Another: 5 mg per serving × 2 servings = 10 mg total (common in beverages)
Piece size vs. serving size (don’t get tripped up)
- A 20 mg gummy can be labeled as 2 servings of 10 mg. Eat the whole piece → 20 mg.
- Chocolates with segmented bars may define ½ square as a serving. Read the fine print.
Label cues to scan: Serving size, Servings per container, and Amount per serving.
Worked examples (clipboard-friendly)
- Gummies (classic): 10 mg per serving, 10 servings → 100 mg total
- Beverage (sessionable): 5 mg per serving, 2 servings → 10 mg total
- Large piece: 20 mg per piece; serving = ½ piece → 10 mg per serving (but 20 mg if you eat the whole piece)
- Variety pack: 10 pieces × 5 mg each → 50 mg total
“Delta-9 mg” vs. “Total THC” on COAs
- Edible labels: shown in mg of Delta-9 THC per serving and per package.
- COAs may show Δ9 THC (mg/g or %), sometimes THCA, and a calculated Total THC for raw inputs. For edibles, focus on the Δ9 mg results for the finished batch and make sure the batch/lot number matches your package.
Net weight, percent, and why mg is clearer for edibles
Percent by weight is useful for flower. For edibles, the practical number is mg—you consume servings, not percentages. When in doubt, rely on mg per serving and total mg.
How to verify potency on the COA (3 steps)
- Batch match: COA lot number = the lot on your package.
- Potency panel: Look for Δ9 THC mg for the finished product; confirm it aligns with the label.
- Safety panels: Residual solvents (if extracts used), pesticides, heavy metals, microbes, mycotoxins; confirm test date and lab.
Edible Label Decoder: Common label pitfalls (and fixes)
- Half-piece servings: If a serving is “½ gummy,” a full gummy doubles your intended mg.
- Mini pieces: Two small pieces might equal one serving—read carefully.
- Old COAs: If the COA is from a different batch, ask for the current one.
- Ambiguous drinks: Some cans are 2 servings; don’t assume the whole can is 1.
Buyer’s quick checklist
- mg per serving clearly stated
- Servings per package listed
- Total mg simple to calculate
- Batch-matched COA available by QR/link
- Safety testing present and recent
- Storage guidance (cool, dry, sealed)
FAQs
Is 10 mg always one gummy? Not necessarily. Some brands make 20 mg gummies labeled as two 10 mg servings.
Why does the COA show percentages? Labs sometimes report % and mg/g. For edibles, use the Δ9 mg result for the finished product to confirm the label.
Do drinks list mg the same way as gummies? Yes—mg per serving and servings per container. Some cans are single-serve; others are 2-serve.
What if the COA mg and label mg don’t match? Check batch numbers first. If they match and still differ meaningfully, contact the brand for clarification.
Key takeaways
- Learn the three lines: serving size, mg per serving, servings per package.
- Multiply to get total mg; don’t assume one piece = one serving.
- Confirm the COA for the same batch and review safety panels.
