Where Do Cannabis Grading Letters Come From?
Every specialist market invents a shorthand, and most of them are stranger than they look. Cannabis produced one of the odder examples: a grading scale made entirely of the letter A.

You will see AA, AAA, AAAA and sometimes AAAAA on Canadian retail listings, including at shops like Buy My Weed. Sales there are restricted to Canada and to adults, so what follows is about vocabulary and not about buying anything. The letters are worth explaining because no regulator ever defined them.
What Does a Letter Grade Actually Describe?
Appearance, mostly, plus a general impression of care.
AAAA is a marketing label rather than a measurement, and the qualities behind it are still consistent enough to describe. More As are meant to signal denser buds, more visible resin, better trim work and a stronger aroma. Fewer As suggest looser structure, rougher trimming or duller color.
What it does not describe is potency. A product can look excellent and test lower than something that looks ordinary, because appearance and chemistry are only loosely related.
The spoken forms became their own vocabulary:
● Quads, meaning AAAA.
● Trips, meaning AAA.
● Dubs, occasionally used for AA.
That is a familiar pattern. A written shorthand gets spoken aloud, the spoken version shortens further, and eventually the spoken form is the one people actually use.
Quads is the clearest case. It is a spoken abbreviation of a written abbreviation, 2 steps removed from the phrase anyone started with. Most people using it have never seen the underlying scale written out in full.
Who Assigns These Grades?
The seller, which is the whole problem.
There is no independent body issuing letter grades. No inspection, no published criteria, no appeal. A retailer decides what to call its own inventory, exactly as a seller might describe something as premium or select.
That makes the scale relative rather than absolute. One shop's AAAA and another's AAA may be indistinguishable, and neither is lying, because there is nothing to lie against.
The absence of a definition is the point. A regulated grade like a food safety rating has published criteria and an inspector, and this scale has neither, which is exactly why it costs nothing to apply.
Two consequences follow directly:
● The scale only works for comparing products within a single seller.
● Grade inflation is inevitable, since no seller gains from being modest.
Anyone who has watched hotel star ratings or restaurant tiers drift upward has seen this before. Self-assigned scales climb.
Why Did the Shorthand Survive Legalization?
Because buyers already knew it, and familiarity is worth money.

Canada legalized adult use in 2018 and built a regulated system with mandatory testing and labeling. That system had no place for letter grades, which are subjective by construction. The letters should have died there.
They did not, because they still do a job. A shopper scanning a long list wants a fast quality signal, and a percentage on a label answers a different question. The letters compress several impressions into one glyph, which is exactly what shorthand is for.
Legal ages are set provincially rather than federally, which is worth knowing before assuming a single national rule:
● 18 in Alberta.
● 19 across most provinces.
● 21 in Quebec, following a change that took effect in 2020.
Federal rules on packaging and labeling apply everywhere, and the legislative and regulatory record for them lives with Publications Canada. None of it applies to readers outside Canada, where the position varies enormously.
What Do the Regulated Labels Say Instead?
Numbers, which are duller and considerably more useful.
A compliant label states THC and CBD content, batch identifiers, packaging date and license details. Those are measured and auditable. They also answer a narrower question than the letters do, which is why both persist side by side.
The THC figure is the one buyers misread most often. It is a percentage of dry weight rather than a rating out of 100, and a number 3 points higher does not describe a product 3 percent better at anything.
This is the honest resolution. The informal grade tells you roughly what the seller thinks the product looks like. The regulated panel tells you what is in it. Reading the second is more useful, and reading only the first is how people end up disappointed.
Industry jargon everywhere works this way, whether the subject is cannabis, wine or casino jargon. There is a marketing vocabulary and a measured one, and they rarely agree.
How Does Slang Like This Usually Die?
Slowly, and usually only when something replaces it.
Terms fade when the thing they described stops existing, when a standard body defines a better term, or when the audience that used them moves on. None of those has happened here, and the letters remain useful to enough people to survive.
Linguists have studied this cycle for a long time, and the Linguistic Society of America publishes accessible material on how specialist vocabulary spreads and persists. Trade shorthand tends to outlive its own usefulness by decades.
The likeliest ending is quiet. The letters stay on menus as decoration while buyers make decisions from the test panel, until one day nobody can remember what the fourth A was supposed to mean.
Frequently Asked Questions About Cannabis Grading Terms
Is AAAA an Official Standard?
No. It is seller-assigned shorthand with no regulatory status, no defined criteria and no independent verification.
Does a Higher Grade Mean Higher Potency?
Not reliably. The letters describe appearance, and potency is printed separately on regulated packaging.
Where Did the Letter Scale Originate?
In informal retail practice rather than any published system, borrowing the familiar A-grade convention used across many consumer goods.
Why Do Sellers Still Use It?
Because customers recognize it instantly. A term with 20 years of familiarity behind it is commercially difficult to abandon.
Reading a Menu With Two Vocabularies
Letter grades are a good example of how specialist language actually behaves. They were invented by sellers, adopted by buyers, shortened into slang, and then survived a regulatory system that had no use for them.
That is the normal life of trade shorthand rather than an exception. The slang terms attached to any specialist market follow the same arc.
The reader's job is simply knowing which vocabulary is which. One was written to describe. The other was written to sell.
