THC vs. THCA: What the Numbers on Your Pre-Roll Label Actually Mean
Pick up a legal pre-roll in Colorado and you may see something that looks confusing:
THCA: 34.7%
THC: 1.2%
So is the product 34.7% THC, 1.2% THC — or somewhere in between? Here’s the two-minute explanation that makes those numbers much easier to understand.
THCA is the precursor to THC
Fresh cannabis typically contains much more THCA (tetrahydrocannabinolic acid) than THC. THCA itself is not considered intoxicating in the same way THC is. When cannabis is heated — by smoking, vaping, or cooking — much of the THCA undergoes a chemical process called decarboxylation, converting it into THC.
So, in simple terms:
- THCA % — potential THC that can become available through heating.
- THC % — THC already present in the product before you light it.
That’s why a pre-roll can show a very high THCA percentage while showing only a small amount of THC.
How to compare products: Total THC
THCA and THC don’t have exactly the same molecular weight. During decarboxylation, THCA loses carbon dioxide, so laboratories use a conversion factor when estimating potential Total THC. The commonly used calculation is:
Total THC = THC + (THCA × 0.877)
For example, on a label reading THCA 34.7% and THC 1.2%:
34.7 × 0.877 = 30.43
30.43 + 1.2 = 31.6% Total THC
So a product labeled 34.7% THCA / 1.2% THC has approximately 31.6% potential Total THC by weight, based on the standard calculation.
One important point: Total THC represents the product’s theoretical cannabinoid potential. It does not mean your body absorbs that entire amount when you smoke it. Combustion, temperature, inhalation and other factors all affect actual THC exposure.
Why we show you the numbers
At Be One Kind, we believe you should know what’s inside your pre-roll. That’s why our labels provide cannabinoid information such as THCA and THC, along with other tested information where applicable. Rather than looking at one big number, understanding the full label gives you a better picture of the product you’re buying.
When you see a Moonwalkers label showing THCA 34.7% / THC 1.2%, you now know that the 1.2% doesn’t mean it’s a low-potency product. Most of its potential THC is still present in THCA form before the pre-roll is lit.
THC percentage isn’t the whole story
It’s easy to turn cannabis into a competition over who has the biggest THC number. But a number alone doesn’t tell the entire story. The overall experience can vary based on factors including dose, cannabinoid profile, terpene profile, product formulation, freshness, consumption method and individual tolerance.
Terpenes are aromatic compounds responsible for much of cannabis’s distinctive aroma and flavour. Scientists continue to study how terpenes may interact with cannabinoids and influence the overall cannabis experience, but those effects are not yet understood well enough to say that a particular terpene profile will create a specific effect for everyone.
That’s why we don’t believe choosing cannabis should simply mean finding the highest THC percentage on the shelf. It’s a little like choosing wine only by alcohol percentage.
Why the Mini format matters to us
Terpenes are volatile aromatic compounds, and aroma and flavour can change as cannabis is exposed to heat, air, light and time.
That’s one reason we built Be One Kind around the 0.35g Mini format. Instead of lighting a larger joint, putting it out, storing it and relighting it later, a Mini is designed to be enjoyed as a smaller single-session pre-roll.
Fresh Mini. Fresh session. No leftovers required.
Quick label-reading checklist
When you’re choosing a pre-roll, don’t look at just one number. Look at:
Total THC
If it isn’t listed, you can estimate it using THC + (THCA × 0.877).
THCA & THC
These show how the product’s THC potential is distributed before heating.
Terpene profile
Look at both total terpene content and, when available, which individual terpenes are present.
What’s inside
Understand whether you’re buying flower, an infused product, or another formulation.
Infusion type
For infused pre-rolls, find out what’s being added — such as kief, concentrate, hash or THCA.
Package and production information
Freshness and proper storage can matter, particularly for aroma and flavour.
FAQ
Does THCA get you high?
THCA in its unheated form is not considered intoxicating in the same way THC is. When you smoke or otherwise heat cannabis, much of the THCA can convert into THC. That’s why a high-THCA pre-roll can still be a high-potency cannabis product when smoked.
Why is the THC number on my label so low?
Because much of the product’s potential THC may still be present as THCA. To estimate Total THC, use THC + (THCA × 0.877).
What’s considered a high THCA percentage?
Potency varies widely by flower, genetics, cultivation, processing, testing laboratory, and whether a product is infused. Rather than relying on a universal cutoff for what is “strong”, compare the product’s Total THC, formulation, serving size and other label information. Infused pre-rolls may also test substantially higher than traditional flower, because cannabinoids or concentrates have been added.
Is higher THC always better?
Not necessarily. Higher THC means greater cannabinoid concentration, but it doesn’t guarantee a better experience. Dose, tolerance, product formulation, aroma, flavour, cannabinoid profile, terpene profile and individual response can all matter. The biggest number isn’t automatically the best product for you.
What is CBG on the label?
CBG (cannabigerol) is one of the many cannabinoids naturally found in cannabis. It is generally present at much lower concentrations than THC in most products, and is part of the plant’s broader cannabinoid profile.
Know what you’re smoking
Cannabis labels shouldn’t require a chemistry degree. Remember one simple idea: THCA is potential, and heat converts much of it to THC. And when you want to compare potency:
Total THC = THC + (THCA × 0.877)
