How to Read Cannabis Labels

Required Label Information

Legal cannabis products must include specific information on their labels as mandated by state regulations. Required elements typically include: licensed producer name and license number, product name and type, total weight or volume, THC and CBD content (total mg and mg per serving for edibles), batch or lot number for traceability, testing laboratory and date, expiration or best-by date, state-required health warnings, and a universal cannabis symbol. Requirements vary by state.

Understanding Potency on Labels

For flower: label shows THC and THCA percentages, with some labels showing "Total THC" (the calculated amount after decarboxylation). For edibles: label shows mg THC and CBD per serving and per package. A 10mg gummy in a 10-pack = 100mg total. Some products show both THC and CBD, plus minor cannabinoids. Higher mg does not automatically mean better — match the dose to your tolerance and needs.

Batch Numbers and COA Verification

Every legal cannabis product has a unique batch or lot number. This number allows you to look up the specific Certificate of Analysis (COA) for that batch at the testing lab's website or the producer's website. Scan the QR code on the label if present — it should link directly to the COA. Verify the batch number on the label matches the COA sample ID. If numbers don't match or no COA is available, consider this a red flag.

Warning Labels and Safe Storage

All legal cannabis products carry state-mandated warnings including: "Keep out of reach of children and pets," impaired driving warnings, pregnancy warnings, and health risk disclosures. Child-resistant packaging is required in all legal states. Store cannabis products in their original child-resistant packaging or in a locked container. Edibles are especially dangerous to children as they resemble regular food — 100mg of THC in a gummy package could cause serious illness in a child.
