What is THCA?
THCA is the acidic form of THC that cannabis actually produces. It is not intoxicating as it sits in the raw plant. Heat converts it to THC — smoking, vaping or baking all do it — which is why a certificate reports total THC after that conversion rather than before.
What is THCA?
Tetrahydrocannabinolic acid: the compound a living cannabis plant makes. THC is what THCA becomes. Raw flower is mostly THCA by weight and very little THC, and eating it raw would not intoxicate you, because nothing has supplied the heat that drives the conversion.
How does THCA become THC?
Heat. The reaction is called decarboxylation: the acid group leaves as carbon dioxide and what remains is THC. A lighter does it instantly, a vaporiser does it on the way through, and an oven does it slowly — which is why edible recipes tell you to bake the flower before you cook with it.
Why does a certificate show both?
Because they are different numbers and only one of them matters to you. A panel reports THCA and THC separately, then a total THC figure that accounts for the conversion, applying the standard 0.877 factor to the THCA to allow for the weight lost as CO₂. Adding the two raw numbers together instead overstates potency, which is one of the easier ways a label flatters itself. Every Cannalab47 batch publishes the whole panel — how to read one.
| On the certificate | What it means | Use it for |
|---|---|---|
| THCA | The acid form, as the plant made it | Understanding the raw material |
| THC (delta-9) | What is already converted in the jar | Usually a small number |
| Total THC | THC + (THCA × 0.877) | This is the figure to compare batches on |
What is THCA flower?
A product category sold in some markets as hemp, on the basis that the federal threshold is written against delta-9 THC at 0.3% by dry weight and THCA is not delta-9. State law varies on this and overrides the federal position in many places, so whether it is lawful where you are is a question for your own state rather than one this page can answer.
Is THCA stronger than THC?
The question does not quite work. THCA is not intoxicating in its raw state, so it is not weaker or stronger — it is the precursor. Once heated it becomes THC, and what you experience is the THC. A high THCA number tells you there is a lot of potential THC in the jar, not that the jar is doing something different.
Questions people actually ask
What is THCA?
The acidic form of THC that the cannabis plant actually produces. It is not intoxicating as it sits in raw flower. Heat converts it into THC, which is why certificates report a total THC figure that accounts for the conversion.
Does THCA get you high?
Not in its raw state. Eating raw flower will not intoxicate you because nothing has supplied the heat that converts THCA into THC. Smoking, vaping or baking that same flower does supply it, and then it will.
What is the difference between THCA and total THC on a lab report?
THCA is the acid form as the plant made it. Total THC accounts for what that becomes once heated, adding THC to THCA multiplied by 0.877 to allow for the weight lost as carbon dioxide. Total THC is the figure worth comparing batches on.
Is THCA flower legal?
It depends entirely on your state, and this page cannot answer it for you. It is sold in some markets as hemp on the basis that the federal 0.3% threshold is written against delta-9 rather than THCA; many states legislate against that reading and their law overrides. Cannalab47 sells state-licensed adult-use cannabis only.
