You’re standing in your kitchen holding two different labels
One bag says “25 mg CBD per gummy.” Another says “Total THC: 0.8 mg per gummy, Delta-9 THC: 0.6 mg per gummy.” A third lists only “Hemp Extract Blend” with no numbers at all. This guide is part of our Cannabis and Cannabinoid Science coverage, and it walks you through reading those three numbers the way they’re meant to be read — without guessing at what isn’t printed on the label.
This is a reading guide, not a dosing guide. It will not tell you how much CBD or THC is right for you, and it will not tell you what effects to expect. Nobody can tell you that from a label alone.
If something already went wrong, start here first
If a child or pet has eaten hemp gummies and you don’t know how much, or if you or someone else is feeling unwell, confused, having trouble breathing, or unusually sedated after eating a hemp product, don’t wait to work out the math. Call 911 for a medical emergency, or contact Poison Control at 1-800-222-1222 (available 24/7 in the U.S.) and bring the label or packaging with you. The rest of this guide is for reading labels calmly, before or after the fact — not for handling an active emergency.
Stage 1: What the three terms on the label actually mean
Hemp gummy labels can list up to three separate cannabinoid numbers, and they are not interchangeable:
- CBD (cannabidiol) — a compound found in the hemp plant that does not produce intoxication. This is usually the largest number on the label.
- Delta-9 THC — the specific form of THC that federal law measures to decide whether a hemp product is legal. Under the 2018 Farm Bill, hemp is defined as cannabis with “a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis” (7 U.S.C. §1639o), so this number exists on the label because of that legal line, not because it’s optional detail.
- Total THC — a lab’s combined figure for THC-type compounds in the product, which can be equal to or higher than the Delta-9 THC number alone, depending on what else the lab tested for. Federal law doesn’t set one official formula for this calculation, so trust the number your specific lab reports rather than trying to calculate it yourself.
If a label shows only one of these three numbers, or none of them, that’s information too — see the “What’s missing” checklist below.
Stage 2: Where these numbers should come from
A reliable hemp product label reflects results from a Certificate of Analysis (COA) — a lab test report tied to a specific production batch. Look for:
- A batch or lot number on the package that matches a batch number on the COA (if one is provided or linked)
- The name of the testing lab, not just “lab tested” with no lab named
- A test date, so you can tell whether the numbers are current or from an old batch
- Cannabinoid amounts reported in milligrams (mg), not just percentages — percentages alone don’t tell you the amount in one gummy
The Medical Disclaimer on this site explains why we describe label-reading mechanics rather than telling you what a given result means for your body — that’s a judgment call between you and a healthcare provider, not something a label or an article can make for you.
Stage 3: The actual serving math
This is the calculation readers usually get stuck on. Hemp gummy labels report cannabinoids at three different levels, and mixing them up is the most common label-reading mistake:
- Per gummy (per piece) — the amount in one single gummy. This is what you eat if you take one.
- Per serving — the amount in whatever the label defines as “one serving,” which is not always one gummy. Some labels define a serving as two or three gummies. Read the serving size line before you read the mg number next to it.
- Per container (total) — the amount in the entire bag or bottle, meant only for calculating cost-per-mg or how long a container will last, not as a single-sitting amount.
A simple worksheet to fill in from your own label:
- Number of gummies per container: ______
- Gummies per serving (as defined by the label): ______
- CBD per gummy: ______ mg → CBD per serving: ______ mg (multiply by gummies-per-serving)
- Delta-9 THC per gummy: ______ mg → Delta-9 THC per serving: ______ mg
- Total THC per gummy: ______ mg → Total THC per serving: ______ mg
- Total THC per container: ______ mg (multiply per-gummy Total THC by total gummies in the container)
Filling this in for any two products puts their numbers on the same footing, which is the only way to compare them honestly — comparing “per gummy” on one label to “per serving” on another will make products look more different, or more similar, than they actually are.
Where the legal 0.3% line fits into this math
The 0.3% delta-9 THC threshold in the Farm Bill is measured on a dry weight percentage basis of the raw hemp plant material — it is not a milligram limit on a finished gummy, and it is not the same measurement as the “per gummy” or “per serving” numbers on a consumer label. A product can be legally compliant hemp under that dry-weight test and still list a specific milligram amount of Delta-9 THC per gummy on its consumer label — those are two different measurements answering two different questions. Don’t assume “hemp-derived” or “legal under the Farm Bill” on a label means the milligram THC number is zero; check the milligram number itself.
What the FDA has and hasn’t approved
It’s worth knowing what federal oversight actually covers here, because label claims sometimes imply more approval than exists. The FDA has approved exactly one CBD drug product, Epidiolex, for specific seizure conditions in patients age 1 and older — and states plainly that “there are no other FDA-approved drug products that contain CBD.” Separately, the FDA has stated that CBD is excluded from the legal definition of a dietary supplement, and that it is a prohibited act to introduce into interstate commerce any food to which THC or CBD has been added. The agency has also warned that “selling unapproved products with unsubstantiated therapeutic claims is not only a violation of the law, but also can put patients at risk.”
None of this means hemp gummies are illegal to sell — states regulate this market in different ways. It means there is no FDA-set serving size, no FDA safety review, and no FDA-approved health claim behind a hemp gummy label the way there is behind an approved drug. The label is the manufacturer’s own reporting, which is exactly why learning to read it carefully matters.
What’s missing: a red-flag checklist
Run any label through this list before assuming it’s telling you everything:
- No serving size stated (only “per container” or “per bag” numbers) — you can’t do accurate per-serving math without this
- No Delta-9 THC number, only “Total THC” or only “hemp extract” with no cannabinoid breakdown
- No named testing lab, or a lab name you can’t verify exists
- No batch or lot number, or a batch number that doesn’t match anything on the package
- No test date, so you can’t tell if the numbers are from the batch you’re holding
- Cannabinoid amounts given only as percentages, with no milligram figures
Any one of these missing items is a reason to treat the label as incomplete, not to fill in the gap with an assumption.
A short decision path
- If the label has gummy count, serving size, and both Delta-9 THC and Total THC in mg: you have enough to complete the worksheet above and make an apples-to-apples comparison with another product.
- If any of those is missing: look for a QR code, batch number, or “view lab results” link on the packaging or brand website before assuming the number doesn’t exist — some brands print a shortened label and host the full COA online.
- If you still can’t find it after checking: that’s missing information, not a green light. Whether an incomplete label is a dealbreaker for you is a personal decision, not one this guide makes for you.
- If you have questions about how a specific amount might affect you personally: that’s a question for a pharmacist or healthcare provider, particularly if you take other medications, are pregnant or breastfeeding, or are making a decision on behalf of a child.
Frequently asked questions
Why do “Delta-9 THC” and “Total THC” show different numbers on the same label?
They’re measuring different things. Delta-9 THC is one specific compound. Total THC is the lab’s combined figure across the THC-type compounds it tested for, so it can be equal to or higher than the Delta-9 THC number alone. A label showing both isn’t a printing error.
Does “under 0.3% THC” mean a gummy has almost no THC in it?
Not necessarily. That 0.3% figure is a dry-weight measurement of the raw plant material used under the Farm Bill’s hemp definition, not a milligram limit on the finished gummy. Check the product’s own milligram figure for Delta-9 THC and Total THC per gummy rather than assuming the legal threshold tells you that number.
Is a hemp gummy “FDA approved” if the label says it’s hemp-derived and legal?
No. The FDA has approved one CBD drug product (Epidiolex) for specific medical uses. A hemp gummy being legally sold under state and federal hemp rules is a separate question from FDA drug approval, and the label wording “hemp-derived” or “Farm Bill compliant” does not indicate FDA approval or review.
What if the label only lists percentages, not milligrams?
Percentages alone don’t tell you the amount in a single gummy or serving without knowing the gummy’s total weight, which most consumer labels don’t provide. Treat a percentage-only label as missing the practical serving information you need, per the checklist above.
What if the batch number on the package doesn’t match the lab report I find online?
Treat that as a mismatch, not a minor detail — a COA is only meaningful if it’s tied to the exact batch you’re holding. If the numbers on the package and the online report don’t line up, the safest read is that you don’t have verified lab results for this specific product in front of you.
The short version
Read the serving size before the milligram number next to it. Keep Delta-9 THC and Total THC as separate figures — don’t average or combine them yourself. Treat the 0.3% Farm Bill threshold as a legal dry-weight test, not a per-gummy milligram limit. And if a label is missing a testing lab, batch number, or serving size, that’s a gap in the information you were given, not a gap you need to guess your way across.
