What Is Bubble Hash? How to Read a Cannabis Product Label
A cannabis label can look intimidating — strain name, THC and CBD percentages, batch numbers, harvest dates, terpene rounds, regulatory icons, and sometimes a QR code linking to a lab report. Here’s how to read every part of the label so you walk out of a dispensary confident in what you’re buying.
Key Details
Strain, Weight, and Type
The top of every cannabis label shows the strain name, the product type (flower, concentrate, edible), and the package weight or count (grams for flower, milligrams of THC for edibles).
The strain name connects the product to its lineage and effect profile. The weight is the basis for pricing and possession-limit calculations.
Cannabinoid Percentages
The next section shows cannabinoid potency — usually THC and CBD percentages, sometimes broken into Total THC, Δ9-THC, THCA, and the CBD equivalents. Premium products may also list CBG, CBN, CBC, and THCV.
Total THC is the practical number to compare across products. Listed in mg for edibles and concentrates, in % for flower.
Terpene Information
Some products list terpene percentages directly on the label. Others reference the COA via QR code. The dominant terpene (myrcene, limonene, caryophyllene, etc.) is the strongest predictor of how the product feels and tastes.
If terpenes aren’t on the label, scan the QR code or ask a budtender to pull the COA. The terpene profile is one of the most useful pieces of information for picking the right strain.
Compliance and Tracking Info
Colorado labels include the state-required warning symbol, batch ID, harvest date or production date, and the licensed cultivator/manufacturer name. There’s usually a ‘Best By’ or ‘Use By’ date for edibles.
Childproof packaging requirements mean the label is on tamper-evident packaging. Resealable bags, tubes, and jars are all common.
How to Use the QR Code
Scanning the QR code links to the full Certificate of Analysis (COA) — the lab report with full cannabinoid breakdown, terpene profile, and contaminant test results. Worth checking for premium purchases.
If the QR code doesn’t work or isn’t there, ask a budtender at any Social Dispensary location to pull the COA. They can access lab data for any batch on the shelf in seconds.
Frequently Asked Questions
What’s required on a Colorado cannabis label?
Strain, product type, weight, cannabinoid percentages, batch ID, harvest/production date, cultivator name, and state warning symbols.
How do I find the THC percentage?
It’s listed in the cannabinoid section, usually as ‘Total THC’ or ‘THC %.’ For flower, it’s a percentage; for edibles, it’s mg per serving and per package.
What does the QR code link to?
The full Certificate of Analysis — the lab report with cannabinoids, terpenes, and contaminant tests.
Why are there warning symbols?
Colorado requires the THC warning symbol on every package containing THC. It’s a regulatory compliance requirement.
Can I trust the percentages on the label?
Yes. Colorado-licensed labs test every batch. There’s been industry discussion about lab-to-lab variability, but the values on a compliant label come from a regulated test.
