How to Read a Cannabis Label: THC, CBD, and Dosing Explained
Learn how to read a cannabis label: total THC vs. THCA, milligrams per serving, terpenes, batch numbers, and COAs, so you know the dose before you buy.
Shopping for cannabis online gets easier once you know how to read a product label. A complete label tells you how potent the product is, how much counts as one serving, and how it was tested. Before you add anything to your cart, scan for the details below so what arrives matches what you ordered.
Key Features to Check
- Cannabinoid potency listed as total THC and CBD, in both milligrams per package and milligrams per serving.
- Serving size and total servings per package, so you can calculate a dose instead of guessing.
- Strain classification (indica, sativa, or hybrid) along with the specific cultivar name.
- Terpene profile when the producer publishes one, since terpenes shape aroma and effect.
- Batch or lot number that ties the package to a specific lab test result.
- Manufacture, harvest, and expiration dates rather than a vague "best by" note.
- Extraction or production method, such as CO2, hydrocarbon, distillate, live resin, or solventless.
- State license number, required health warnings, and a scannable certificate of analysis (COA).
Labels on legal cannabis products sit on child-resistant, tamper-evident packaging that also carries a license number and a batch code. Potency appears two ways: a percentage by weight and total milligrams per package. Because a percentage describes concentration rather than dose, the milligram figure is usually the more useful number when you compare a gummy with a vape cartridge. If a label lists THCA separately, remember that it converts to THC when heated, and some states require the label to show total THC after conversion. Ingredients, allergens, and carrier oils belong on the panel too, especially for tinctures and edibles.
cannabis label terms explained
Orders ship discreetly in plain, unmarked packaging with no product names on the outside, and tracking is shared as soon as the shipping label is created. If an item arrives damaged, incorrect, or short of the listed quantity, contact support within the window stated in the shop policy and include a photo of the label and packaging. Sealed, unused items are typically eligible for replacement rather than return, since opened cannabis cannot be resold.

Why does the batch number matter?
A batch or lot number links your exact package to the lab results the producer published for that run. Look it up in the brand's certificate of analysis database to confirm potency, pesticide screening, and microbial testing for the product in your hand, not just for the strain in general.
How to Interpret Cannabis Expiration Dates
How do I compare THC percentages with milligrams?
Percentages describe concentration in the flower or oil, while milligrams describe the total amount in the package or per serving. For edibles and tinctures, divide the total milligrams by the number of servings to reach a dose you can actually measure.
What safety warnings should appear on a legal label?
Expect a government warning, a keep-out-of-reach-of-children statement, an age restriction notice, and a caution about driving or operating machinery. Some states also require symbols or advisories for pregnant and breastfeeding people.
