Reading Labels: How to Understand a New York Cannabis Package
This page is general information for adults 21+ about legal cannabis in New York. It is not medical or legal advice and does not claim that cannabis treats, cures or prevents any condition. Talk to a licensed healthcare provider about your health.
Every product at Pure Leaf Flower is packaged to one rulebook: New York's packaging and labeling regulation, 9 NYCRR Part 128. It tells licensed processors what must appear on a package and in what words, which is why products from different companies carry the same warnings in the same language. Every lot is also tested by a licensed laboratory under Part 130, and those results travel with the product as a Certificate of Analysis (COA). Learn to read a panel and you can compare products quickly and spot a package that does not belong in the legal market. (Source: NY OCM.) New here? Start with First-Time Visitors.
The universal symbol
Look for New York's cannabis universal symbol on the outermost layer of the package. OCM publishes three approved formats with minimum sizes: the square format at 1.25 inches high, and the vertical and horizontal formats at 0.5 inch. Any THC product made for New York's regulated market carries it, unaltered. No symbol is the clearest sign a product did not come from a licensed New York supply chain.
Potency: percent for what you inhale, milligrams for what you swallow
New York splits potency labeling by product type:
- Inhalable products (flower, pre-rolls, vaporizers, concentrates): total THC and total CBD as a percentage, plus net quantity and brand name.
- Non-inhalable products (edibles, tinctures, orals, topicals): total THC and total CBD in milligrams per single serving and per package, plus the number of servings and the serving size.
New York caps an edible serving at 10 mg of total THC, and OCM suggests people new to edibles begin at 2.5 to 5 mg and wait at least two hours before taking more, because edibles can take up to four hours to reach peak effects. OCM's Part 128 guidance states no per-package milligram maximum, so read the "per package" number rather than assuming one. More in Edible Dosing.
Total THC versus THCA
Raw cannabis mostly contains THCA, which converts to THC when heated. Labs report both, then calculate:
- Total THC = THC + (THCA × 0.877)
- Total CBD = CBD + (CBDA × 0.877)
The 0.877 accounts for weight lost in conversion, and the label already shows total THC. For adult-use products, New York allows the labeled potency to fall within 85 to 115 percent of the laboratory result, so a 22 percent flower and a 24 percent flower are closer than they look. A higher THC percentage does not mean a better cannabis experience; form, dose, terpene profile and tolerance all matter. See Terpenes Guide and Cannabis 101.

The warnings, word for word
Part 128 requires these statements on every package, in this exact wording:
- "This product contains cannabis and THC"
- "KEEP OUT OF REACH OF CHILDREN AND PETS. For use only by persons 21 years of age and older"
- "Warning: Do not use if pregnant or nursing"
- "Poison Center 1-800-222-1222"
Packages also carry a warning matched to the product type — a smoking or vaping warning on inhalables, "Warning: Effects of this product may be delayed by 4 or more hours" on edibles, and a topical-use-only warning on topicals — plus one rotating health warning, such as "Cannabis can be addictive." Wording can vary slightly by product category, so read the panel in front of you. (Source: NY OCM.)
The QR code and the Certificate of Analysis
Every package carries a barcode or QR code linking to the COA for that lot. Scan it and check four things: the lot number matches the package, the potency matches the panel, the test date lines up with the packaged date, and every contaminant category shows a pass. Under Part 130, each lot is tested for its cannabinoid profile, terpenes, microorganisms, heavy metals, mycotoxins, pesticides, residual solvents, foreign material and moisture. If the link is dead or shows a different product, tell us.
Child-resistant and tamper-evident packaging
Retail packaging must be child-resistant for the life of the product, tamper-evident, fully enclosing and not attractive to anyone under 21; multi-serving packages must be resealable. Keep products in that original packaging, locked, out of sight and reach of children and pets. If a package arrives open or with a broken seal, do not use it — call us first and we will tell you what to do next.
Red flags: packaging that does not belong here
- No New York universal symbol on the package.
- No lot number, no QR code, or a QR code that leads nowhere.
- No processor name, location or New York license number.
- Cartoon characters, mascots, or imitations of familiar snack brands, which Part 128 prohibits.
- Labels written for another state, or products marketed as "THCA hemp" flower.
- Missing or reworded warnings; New York's language is fixed.
OCM asks shoppers to buy only from licensed dispensaries displaying the Dispensary Verification decal near the entrance, and to check any store against its list (Source: NY OCM).

Bringing it into the store
Labels are easiest to learn with a product in your hand. In-store shopping is open to adults 21 and older with a valid government-issued photo ID; ask a budtender to walk you through a panel and pull up the COA, or browse details on our online menu (flower, pre-rolls). Online ordering, pickup and delivery are shown as coming soon on the menu, so check there or contact us. Whatever the label says, the basics apply: start low and go slow, keep products locked away from children and pets, keep cannabis in New York rather than carrying it across state lines, and do not drive after consuming or ride with an impaired driver — plan ahead for a sober ride.
