The THC percentage on a Massachusetts cannabis label is the lab's measurement of THC (and related cannabinoids) in that batch of packaged flower — not a quality score, and not a ranking of how a product will treat you. A 27% eighth and a 22% eighth are different lab snapshots. The 22% jar can still have a full terpene nose. Use the sticker on the unit in your hand.
We print tests on Gibby's packages because the CCC requires it. We also watch shelf audits. In August 2026 the Commission published a statewide flower potency audit: most samples were in range, some were not. Labels can be wrong. That is why the sticker on the unit in your hand, plus a working nose, beats a blog number.
What the number is
An independent Massachusetts Independent Testing Laboratory assays a sample. The package lists total THC or a related figure. Different shops display it as “THC 27%” or break out THCA. THCA converts when you heat it. If you want the chemistry, read our COA walkthrough.
On our cultivar pages we post a typical figure for the strain as we have run it — MAC 1 around 27%, Cap Junky around 29.5%, White Truffle around 28%. Those are typical, not a promise for the jar you buy on a Thursday in Pittsfield.
What the number is not
- It is not a safety rating.
- It is not “twice as much product” just because it is twice the percentage of another jar.
- It is not a substitute for terpenes. A loud limonene MAC 1 and a mute 30% mystery eighth are different products.
How to use it at the counter
If you are new to a producer, you do not need the highest digit on the board. Tell the budtender the producer you want and how you consume (flower or pre-roll). If you already know Gibby's MAC 1 at ~27% is the cultivar you buy, match the cultivar first, then glance at the batch test so you are not surprised by a different lot.
The CCC's yellow/red bands on audits exist because some packages overstate potency. If a deal looks like 35% indoor from a brand you have never heard of at a price that makes no sense, be skeptical. Our micro-canopy in Uxbridge does not chase cartoon numbers.
Frequently asked questions
Is higher THC always better?
No. Higher THC means more of that molecule in the sample. Flavor, freshness, and the cultivar still decide whether you want that jar.
Why did a Massachusetts audit flag some flower?
The Commission tests packaged flower against the label. Products outside the allowed band get follow-up. That is consumer protection, not gossip.
Where do I see Gibby's numbers?
On the package. Cultivar pages such as MAC 1 show typical tests. The pack wins if they disagree.
