How Much Delta-9 Is in a Legal Gummy?
If you have ever turned a hemp gummy package over and wondered how it can contain Delta-9 THC and still sit legally on the shelf, the answer is one number: 0.3% Delta-9 THC by dry weight. That federal threshold is a percentage, not a fixed milligram count, which is why two compliant gummies can still hold very different amounts of Delta-9. Here is how that percentage becomes the milligrams printed on a label, and how to confirm it yourself.
The 0.3% rule is a percentage, not a dose
The reason a hemp gummy can contain Delta-9 THC and still be sold legally comes from the 2018 Farm Bill, the federal law that defines hemp as cannabis containing no more than 0.3% Delta-9 THC by dry weight. The key word is percentage. The 0.3% figure is a share of the product's weight, not a set number of milligrams, so the actual Delta-9 content depends on how much the gummy weighs.
Everything sold at The Lifted Leaf is hemp-derived and third-party lab tested to stay under that 0.3% line. Rules vary by state and can change, so the federal definition is the starting point, not the whole picture. This page explains the math, and it is not medical or legal advice.
Turning 0.3% into milligrams per gummy
Here is where the percentage becomes a real number. To find the most Delta-9 THC a compliant gummy can hold, take 0.3% of the gummy's weight:
- A gummy weighing about 2 grams (2,000 mg) tops out near 6 mg of Delta-9 THC at the 0.3% line.
- A gummy weighing about 4 grams (4,000 mg) can hold up to roughly 12 mg and still stay under the limit.
- A larger 5-gram (5,000 mg) gummy reaches about 15 mg at the same 0.3%.
That is why you will see compliant gummies labeled with 10 mg of Delta-9 THC: the candy around the cannabinoid is heavy enough that 10 mg is still under 0.3% of its total weight. Heavier gummy, more milligrams allowed. These figures are illustrative examples, so always read the exact numbers on the product in front of you.
Why two legal gummies can be very different
Two gummies can both sit under 0.3% and still contain very different amounts of Delta-9 THC. A few things drive that:
- Gummy weight. As the math above shows, a bigger gummy has more room for milligrams.
- Serving size. Some labels count one gummy as a serving, others count half. The per-serving number is the one that matters.
- Formulation. Makers choose how much Delta-9 to add, up to the compliant ceiling, so not every gummy is maxed out.
- Other cannabinoids. Many gummies also include ingredients like CBD, CBG, or CBN. Those are listed separately and do not count toward the Delta-9 figure. See how the main cannabinoids compare in our guide to Delta-8 vs Delta-9.
How to read the milligrams on the label
The front of the package usually shows a large milligram number, but the detail you want is Delta-9 THC per serving versus per container. A package that says 100 mg total might be ten gummies at 10 mg each. Our full walkthrough of how to read an edible label breaks down every line, and if you are new to edibles, start with the first-time edible guide and how to dose edibles.
Checking the per-serving milligrams is the single best habit for buying gummies with confidence, because it tells you exactly what one piece contains instead of leaving you to work it out from the total.
Confirming it on the COA
The label is the summary; the COA (third-party lab report) is the proof. Every product at The Lifted Leaf has one. On the COA, look for the Delta-9 THC result, usually reported both as a percentage and in milligrams, and confirm the percentage reads under 0.3%. The report should also match the batch or lot number printed on your package. Our guide on how to read a COA shows which rows matter and how to tell that a report actually belongs to the product you are holding.

State rules and what can change
The 0.3% dry-weight standard is federal, but it is not the end of the story. Some states add their own rules, such as a cap on total THC or a maximum number of milligrams per serving or per package, and a handful restrict certain hemp products more tightly. Rules vary by state and can change, sometimes quickly, so a product handled one way in one place may be handled differently in another.
At The Lifted Leaf in Indiana, we sell to adults 21 and older with a valid photo ID, and every product is lab tested to stay under the federal 0.3% Delta-9 THC line. None of this is legal advice. If you have questions about your own situation, check the current rules for your state.

How many milligrams of Delta-9 THC can a legal gummy have?
There is no single milligram cap in the federal rule. The limit is 0.3% of the gummy's dry weight, so a heavier gummy can legally contain more total milligrams. As an example, a roughly 4-gram gummy can hold up to about 12 mg and still stay under 0.3%. Always read the exact per-serving number on the label and COA. Rules vary by state and can change, and this is not legal advice.
Why do some legal gummies say 10 mg of Delta-9 THC?
Because the gummy is large enough that 10 mg is still under 0.3% of its total weight. The candy around the cannabinoid adds weight, which raises how many milligrams can fit under the percentage limit. Rules vary by state and can change.
Is Delta-9 in a hemp gummy the same molecule as in other cannabis?
Delta-9 THC is the same compound regardless of the plant it came from. The legal difference is the source and the concentration: hemp-derived products are capped at 0.3% Delta-9 THC by dry weight under federal law. See our Delta-8 vs Delta-9 guide for how the cannabinoids compare. Rules vary by state and can change.
How do I verify that a gummy is actually compliant?
Check two things. On the label, find the Delta-9 THC per serving and per container. Then open the COA, the third-party lab report, and confirm the Delta-9 reads under 0.3% and the batch number matches your package. Our how to read a COA guide walks through it step by step.
Does the 0.3% limit include CBD, CBG, or CBN?
No. The 0.3% limit applies only to Delta-9 THC. Other cannabinoids like CBD, CBG, and CBN are listed separately on the label and COA and do not count toward that figure.
Can I pick up Delta-9 gummies the same day at The Lifted Leaf?
Yes. The Lifted Leaf in Schererville offers free same-day in-store pickup, and shipping is free on orders over $75. You must be 21 or older with a valid photo ID.
