The legal market loves a number. Numbers fit menus, sorting tools, labels, and quick comparisons. THC percentage is especially seductive because it looks like an objective answer to a subjective question: which one is better?
It is not.
What the number actually tells you
For flower and other inhaled products in Washington, cannabinoid content is listed as a percentage. The state says most flower falls roughly between 12% and 25% THC, with some products higher. In 2022, Washington reported an average flower THC concentration of about 21%.
That is useful potency information. If two otherwise similar products test at 12% and 28%, the difference is not imaginary.
What the number does not tell you
THC percentage does not measure freshness, curing quality, aroma, flavor, moisture, producer consistency, contamination risk, your preferred experience, or whether the product is pleasant to use.
It also cannot account for your dose. A high-potency product used in a small amount and a lower-potency product used in a larger amount are not interchangeable simply because one package has a bigger number.
The market often collapses those two ideas because “more THC” is easy to sort and sell.
Why the myth persists
Partly because THC is one of the most visible standardized values consumers can compare. Partly because high numbers can be marketed as premium. And partly because people naturally assume more of an active ingredient must mean more value.
But a wine with the highest alcohol percentage is not automatically the best wine, and coffee with the most caffeine is not automatically the best coffee. The analogy is imperfect, but the category error is similar.
A better shopping question
Instead of “what has the highest THC?” ask “what information do I actually care about?” If potency matters to you, include it. Then add freshness, producer reputation, aroma, format, price, serving control, and your own prior experience.
The number belongs in the decision. It just does not deserve to be the entire decision.
