Field Notes / NY Label Guide
NY OCM Label Requirements
The New York Office of Cannabis Management requires every adult-use cannabis product to display specific information on its label. Here is what must be present and what each element means.
Product Name
The brand name and product name as registered with the NY Office of Cannabis Management. This identifies exactly what you are purchasing.
Net Weight
The total weight of cannabis in the package, listed in grams or milligrams depending on the product type. This is the weight of the product itself, not the packaging.
Cannabinoid Content
THC and CBD percentages or milligrams. This is the most important number for understanding potency and expected effects.
Manufacture & Expiration Dates
When the product was made and when it expires. Cannabis products degrade over time, losing potency and freshness.
Warning Statements
Required health and safety warnings mandated by NYS. These include statements about age restrictions, impairment, pregnancy, and keeping products away from children.
Batch Number
A unique identifier that traces the product back through the supply chain. If a safety issue arises, this number allows targeted recalls.
Testing Facility
The name of the OCM-approved laboratory that tested the product. Every product sold in NY dispensaries must be tested by an approved lab.
License Number
The processor's or cultivator's OCM license number. This confirms the product was produced by a legally authorized operation.
Ingredients List
Every ingredient in the product, especially important for edibles and tinctures. Listed in descending order by weight, just like food labels.
Allergen Information
Common allergens present in the product such as nuts, soy, dairy, or gluten. Critical for consumers with food allergies or sensitivities.
THC & CBD Numbers Explained
The cannabinoid numbers on your label are the single most important piece of information for predicting your experience. Here is how to read them.
THC Percentage (Flower)
On flower labels, THC is listed as a percentage by dry weight. A label reading "22% THC" means that for every gram of flower, approximately 220mg is THC. Higher percentages produce stronger psychoactive effects. Most flower ranges from 15% to 30% THC.
THC Milligrams (Edibles & Tinctures)
Edibles and tinctures list THC in milligrams per serving and per package. A standard dose for beginners is 2.5mg to 5mg. Experienced consumers may use 10mg to 25mg per serving. Always check the number of servings per package.
CBD Content
CBD is listed in the same format as THC. Products with meaningful CBD content (above 1%) can moderate the intensity of THC, potentially reducing anxiety and producing a smoother experience. Look for balanced ratios like 1:1 (equal THC and CBD) if you want milder effects.
Total THC vs THCA
You may see both "THC" and "THCA" on your label. They are related but not the same thing.
Raw cannabis flower contains very little delta-9 THC. Instead, it contains THCA (tetrahydrocannabinolic acid), which is the non-psychoactive precursor. When you apply heat through smoking, vaping, or baking, THCA converts to THC through a process called decarboxylation.
Think of it this way: THCA is the raw ingredient, and heat is the activation step. The conversion is not perfectly efficient, which is why labels sometimes show a "Total THC" calculation using the formula:
Total THC = (THCA x 0.877) + THC
The 0.877 factor accounts for the weight lost during decarboxylation (the carboxyl group that drops off as CO2). So if your flower label shows 25% THCA and 1% THC, the Total THC is approximately 22.9%. This is the number that best predicts the actual psychoactive strength when you consume it.
Terpene Profiles on Labels
Not all labels include terpene data, but those that do give you valuable information about the aroma, flavor, and potential effects of the product.
Terpenes are the aromatic compounds that give cannabis its smell and flavor. More importantly, they influence the overall experience through what researchers call the entourage effect. Labels that list terpenes typically show the top three to five terpenes by percentage.
For example, a label might read: Myrcene 1.2%, Limonene 0.8%, Caryophyllene 0.5%. This tells you the product has earthy, citrus, and spicy notes, and likely leans toward relaxation (myrcene-dominant profiles tend to be calming).
Total terpene content typically ranges from 1% to 5% in flower. Products above 3% total terpenes are considered terpene-rich and generally offer more pronounced flavor and a more nuanced experience.
Batch Numbers & Certificates of Analysis
Every product in a NY dispensary has been tested and tracked. The batch number is your key to accessing the full lab report.
Batch Number Tracking
The batch number on your label is a unique identifier assigned during production. It connects your specific product to the harvest, extraction, or manufacturing run it came from. If a product is recalled, this number allows the state to identify exactly which units are affected without pulling everything off shelves.
Certificates of Analysis (COAs)
A COA is the full lab report for a specific batch. It includes detailed cannabinoid potency, terpene breakdown, and contamination screening results for pesticides, heavy metals, microbials, mycotoxins, and residual solvents. Many brands provide COA access via QR codes on the packaging or on their website by entering the batch number.
What Is on a COA
- Cannabinoid Profile: Exact percentages of THC, THCA, CBD, CBDA, CBN, CBG, and other cannabinoids
- Terpene Analysis: Individual terpene percentages, often listing 20 or more compounds
- Pesticide Screening: Pass/fail results for dozens of pesticide compounds
- Heavy Metals: Lead, arsenic, cadmium, and mercury levels
- Microbial Testing: Checks for mold, yeast, E. coli, and salmonella
- Residual Solvents: For extracts and concentrates, confirming solvent levels are within safe limits

Warning Labels
NY law requires specific warning statements on every cannabis product. These are not optional or decorative. They include:
- For use only by adults 21 and older
- Keep out of reach of children and pets
- Cannabis can impair your ability to drive
- Do not use if pregnant or breastfeeding
- The universal cannabis symbol (THC warning icon)
Strain Naming Conventions
Strain names like "Blue Dream" or "Granddaddy Purple" are not regulated the same way pharmaceutical names are. The same name from two different growers can produce noticeably different experiences.
What matters more than the name is the actual lab-tested cannabinoid and terpene profile on that specific batch. Use the strain name as a starting point, but rely on the numbers for your decision.
Some producers use proprietary names for their phenotypes. These are unique selections bred from known genetics but may not match what another brand sells under a similar name.
Using Label Info for Decisions
Five steps to turn label information into a smart purchase decision.
Check the THC percentage or milligrams
Start here. This tells you how strong the product is. Lower numbers mean milder effects. Beginners should look for lower potency.
Look at the CBD content
CBD can moderate the intensity of THC. Products with balanced THC-to-CBD ratios tend to produce smoother, less anxiety-prone experiences.
Review the terpene profile
Terpenes shape the experience. Myrcene for relaxation, limonene for energy, linalool for calm. Let the terpenes guide your selection.
Check the harvest and packaging dates
Fresher products generally have better flavor and more intact terpene profiles. Older products may have degraded slightly.
Verify the batch number and testing lab
This confirms the product has been tested and tracked. If you find a product you love, the batch number helps you find it again.
What Labels Don't Tell You
Labels are informative but incomplete. They do not tell you about growing conditions, whether the flower was sun-grown or indoor, the curing process, or the skill of the cultivator. They do not predict exactly how a product will make you feel, because individual body chemistry, tolerance, setting, and mood all influence the experience.
Labels also do not communicate freshness in a way that is immediately obvious. A product within its expiration date may still have degraded terpenes if it was stored improperly before reaching the dispensary shelf.
This is where your budtender adds value. They can share feedback from other customers, note which batches have been popular, and help you interpret label data in the context of what you are actually looking for.
Common Label Reading Mistakes
Five mistakes we see customers make when reading labels, and how to avoid them.
Confusing THC percentage with total THC
The THC percentage on flower labels shows delta-9 THC, but total THC includes THCA that converts when heated. Total THC is always higher than the listed THC percentage.
Ignoring serving sizes on edibles
A package might say 100mg THC, but that is 10 servings of 10mg each. Eating the whole package when you meant to eat one serving is the most common edible mistake.
Assuming higher THC means better quality
THC percentage is one factor. Terpene content, growing conditions, cure quality, and the entourage effect all contribute to the overall experience.
Skipping the ingredient list on edibles
Edibles contain food ingredients beyond cannabis. If you have allergies or dietary restrictions, the ingredient list is essential reading.
Not comparing unit pricing
A $40 eighth and a $50 eighth at different THC levels have different cost-per-milligram of THC. Compare value on a per-unit basis, not just sticker price.
For use only by adults 21 years of age and older. Keep out of reach of children and pets. Cannabis can impair concentration, coordination, and judgment. Do not operate a vehicle or machinery under the influence of cannabis. Licensed by New York Office of Cannabis Management.
