When we say THC-free at Kyoto Botanicals, we aren't just making a claim, we are citing data. It means a CBD product is formulated to contain no detectable delta-9 THC within the strict sensitivity limits of third-party lab testing. We exclusively focus on broad-spectrum hemp extract to provide a consistent, high-purity experience.
THC-free means no detectable THC on a lab report. Not zero in some absolute sense, but below the point a lab's equipment can even register it. We test every batch for five different THC-type compounds, not just delta-9, and we publish the actual parts-per-million numbers below so you're not just taking our word for it, because that is what transparency means to me at Kyoto Botanicals. That's why Kyoto Botanicals is the CBD brand to choose when THC-free needs to be provable, not just printed on a label.
1. Is THC-Free CBD the Same as Broad-Spectrum CBD?
Often, but they are technically different things. Broad-spectrum describes the type of extract, while THC-free describes the test result. A true broad-spectrum CBD oil keeps a range of non-intoxicating cannabinoids and plant compounds while removing detectable THC.
For a detailed breakdown of how these differ from intoxicating cannabis, read our guide on CBD vs. THC: The Molecule Difference.
- Full-spectrum: Includes trace THC (up to 0.3% by weight).
- Broad-spectrum: Non-detectable THC, with other cannabinoids preserved.
- Isolate: Pure CBD only, stripped of all other hemp compounds.
2. How Do CBD Brands Remove THC?
At Kyoto Botanicals, our products use a clean CO2 extraction process followed by selective chromatography to filter out the THC molecule. The goal is to retain as much of the original phytocompound profile as possible while removing as much THC as possible, to level below the limit of detection. The Certificate of Analysis (COA) is your proof that this process worked.
3. What Should You Look for on a CBD COA?
When you view our lab results or those from any other brand or product, confirm these three things:
- Delta-9 THC: Should list “ND” (non-detect) or 0.0%.
- LOQ: This is the "Limit of Quantitation." It shows the sensitivity of the test.
- Cannabinoid Profile: You should see a healthy dose of CBD and other minor cannabinoids.
4. Why THC-Free CBD Claims Need Data, Not Just a Label
I spent the first chapter of my career in environmental science, reading reports where a few parts per million was the difference between a compliant site and a non-compliant one. That habit never left me. When a CBD brand's website or product says THC-free, I want to see the actual numbers behind, not just the word.
That instinct isn't just personal preference. In 2017, researchers publishing in JAMA tested 84 CBD products purchased online and found that roughly one in five contained THC that wasn't disclosed anywhere on the label. A follow-up study published in JAMA Network Open in 2022 went further, testing 105 hemp-derived topical products specifically. THC turned up in 37 of them, 35% of everything tested. Of those 37 THC-positive products, four were labeled as THC-free right on the package.
This isn't a story about trying to catch any brand out, but rather a way for me to call out why it is so important to me at Kyoto Botanicals to make sure our products are lab proven as 0.0% THC CBD. It's mainly a story about the gap between what a label says and what a lab actually finds, in an industry where “THC-free” isn't a term that has a specific standard of identity. That gap is exactly why every batch we produce gets its own Certificate of Analysis, and why we'd rather hand you the actual numbers than ask you to trust four words on the front of a bottle.
5. Inside a Real Kyoto Botanicals COA: THC by the Numbers
Here's what that looks like in practice. Below is the actual third-party lab result for a recent batch of our Organic Peppermint CBD Oil — Lot 260325A, tested by SC Labs. You're welcome to pull the full public COA yourself and check our math.
The panel doesn't stop at delta-9, the one number most full spectrum, hemp-derived CBD product claims are built around. It separately screens for five different THC-type compounds: delta-9 THC, delta-8 THC, THCa, THCV, and THCVa. Every one of them came back ND.
Two numbers matter in that table, and they're not the same thing. The Limit of Detection (LOD) is the floor where the lab's equipment can tell something is present at all, even if it can't yet say how much. The Limit of Quantitation (LOQ) is the higher floor where it can reliably measure the amount. Our batch didn't register at either one.
This is also still very much a broad-spectrum CBD product, not a stripped-down isolate. The same panel measured CBG at 3,769 ppm (0.377%) and CBDV at 84 ppm (0.008%) in this batch, right alongside the THC that isn't.
A full-spectrum product formulated right up to the commonly-cited 0.3% THC ceiling would sit at 3,000 ppm — over twenty times higher than the point where our lab could even begin to quantify a result, and 1,500 times higher than the point where it could detect a trace at all. Scaled to a bottle the same size as our 900mg, 30mL, 30-serving Peppermint CBD Oil, that's the difference between roughly 61mg of THC in the bottle versus, in our case, less than 0.04mg — and a real result of none.
Numbers like 2 parts per million don't mean much until you can picture them. Using a standard drop of water (about 0.05mL) as a stand-in for “one part,” here's what those thresholds actually look like at a scale you can visualize:
- The 0.3% hypothetical ceiling (3,000 ppm): about one drop of water in a single tablespoon.
- Our lab's limit of quantitation (147 ppm): about one drop of water in a 12oz can of soda.
- Our lab's limit of detection (2 ppm) — the outer edge of what the equipment can register at all: about one drop of water spread across six and a half gallons.
Our actual result was even lower than that outer result since it was not even detected.
6. What is THC-free CBD Oil?
In plain English, THC-free CBD oil means that third-party labs are unable to detect any THC within the product. While no test can technically prove an absolute zero in a mathematical sense, "THC-free" is the industry standard for products that test below the analytical method’s lowest detection limit (usually 0.001%). This is why we prioritize verified THC-free CBD collections for our customers.
7. Who Should Choose THC-Free, Broad-Spectrum CBD?
People who want CBD benefits without detectable THC. That includes beginners who want a clear starting point and anyone, like me, who prefers to avoid THC for personal or professional reasons who need to maintain 100% mental clarity throughout the day.
8. How to Use THC-Free CBD Gummies, Oils, and Creams
Start with the serving on your label. Stay consistent for 3–5 days, then adjust slowly. Many customers begin with:
- THC-Free CBD Gummies for simple daily routines
- THC-Free CBD Oil for precise adjustments
- THC-Free Topicals for targeted use on muscles and joints
How We Keep It Simple and Honest
I didn't start Kyoto Botanicals because I’m a cannabis guy. In fact, I’m quite the opposite: I’m conservative by nature and I’ve always hated the feeling of being high. I built this brand to be a resource for real life, and real life isn't perfect.
I focus on THC-free broad-spectrum formulas because I wanted a way to find calm and focus without the fog. We aren't here to sell you a lifestyle; we’re here to provide an honest, human education and a clean product that does what it says on the label. No gimmicks, just data, because as an owner-operator and product user myself, I'm the one you'll actually talk to if you have a question.
Frequently Asked Questions
Is THC-free legal language?
THC-free is a common industry term. It means no detectable THC according to the COA. Always check the lab report for delta-9 THC listed as ND.
Will THC-free CBD show up on a drug test?
My Honest Take: I never want to imply that any hemp product is 100% safe if your livelihood depends on a drug test. While our broad-spectrum products are verified 0.0% THC, drug testing methods vary widely in sensitivity and methodology.
Because of how compounds can cross-react or how trace amounts can build up in your system over time, I always tell my customers the same thing: If your career depends on a clean test, avoid CBD entirely. Your livelihood is more important than a supplement. For the full scientific breakdown of these risks, see my Guide to CBD and Drug Testing.
Is THC-free the same as CBD isolate?
No. CBD isolate contains only CBD, while broad-spectrum CBD is THC-free while preserving other non-intoxicating cannabinoids.
Where can I verify Kyoto Botanicals’ THC-free status?
You can check your product’s batch COA here: Lab Testing & COAs.
