Full Spectrum Under 0.3% THC, Explained
The number on every full-spectrum hemp label is a legal line, not a promise of zero THC. Here is what it means, what it does not, and how to read it honestly.
The short version
0.3% is the 2018 Farm Bill hemp line — cannabis at or under 0.3% delta-9 THC by dry weight is hemp and is federally legal. Above that line it is marijuana.
Full-spectrum oil keeps that legal trace THC along with the rest of the plant profile. It is not “THC-free with a rounding error.”
THC-free means ND or <LOQ on the COA, which is how broad-spectrum and isolate are sold. A label that says “< 0.3% THC” is describing legal hemp, not zero.
If you are drug-tested, that number is the whole decision. Buy broad-spectrum. Keep the batch PDF.
What the Farm Bill actually drew
Hemp and marijuana are the same species. Congress drew a number: 0.3% delta-9 THC by dry weight. At or under that line the plant is an agricultural commodity. Above it, Schedule I. The CBD molecule is identical on either side. Everything that differs — who can sell it, whether it ships, whether a workplace screen cares — follows from that number.
A finished full-spectrum tincture is still hemp-derived when the plant and the product stay inside that cap. It is also still a bottle that contains THC. Those two sentences are both true. Brands that collapse them into “non-detectable because it is legal” are not being honest.
ND, <LOQ, and < 0.3%
- ND — the lab did not see THC above its detection limit. This is what you want on a THC-free bottle.
- <LOQ — maybe a whisper, not a number the lab will stand behind. Still not a percentage under 0.3%.
- < 0.3% — legal hemp. On a daily full-spectrum habit, still enough THC to matter for a workplace screen. See Will CBD Show Up on a Drug Test?

Why the number is being rewritten
P.L. 119-37 §781, signed November 12, 2025, moves federal hemp toward a total-THC standard and caps a finished consumer product at 0.4 mg of total THC per container — per bottle, not per serving. That is far below what a typical full-spectrum 30 mL oil contains. Provisions were set for November 12, 2026; H.R. 6500 later pushed most of them to December 11, 2026. Converted intoxicants such as delta-8 still lose federal hemp status on the earlier date as written.
None of this bans CBD. Pure CBD and THC-free broad-spectrum oils are not the target. Full-spectrum oil is the category with a real question mark. Dates have already moved. We will update this page rather than pretend a deadline is carved in stone. Our hemp-vs-marijuana comparison carries the same caveat.
Which botanCBD bottle matches which sentence
Full-spectrum drops: hemp-derived, Farm Bill compliant, under 0.3% THC, complete plant profile. Buy this only if you are not tested and you want that profile on purpose.
Broad-spectrum drops: same plant family minus THC, formulated to be non-detectable, the bottle we point at drug-tested jobs and at states that want zero THC. Email the batch number; we send that PDF the same day.
FAQ
Does 0.3% THC mean the bottle is almost THC-free?
No. 0.3% is the legal hemp cap on the plant (delta-9 THC by dry weight under the 2018 Farm Bill), not a synonym for zero in the oil you take every day. A 30 mL full-spectrum bottle can contain a real milligram amount of THC even while it stays legal hemp.
What should a THC-free COA say?
ND (not detected) or <LOQ (below the limit of quantification) on the delta-9 THC line. '< 0.3%' is the legal cap. If the marketing said THC-free and the THC line is a percentage under 0.3%, that is full-spectrum-shaped labeling.
Will full-spectrum CBD make me fail a drug test?
It can. Workplace screens look for a THC metabolite, not for CBD. Daily full-spectrum use can accumulate. Broad-spectrum is the THC-free oil. No brand can guarantee your employer's cutoff. See our drug-test guide.
Is 0.3% enough to get me high?
Not at ordinary servings of hemp-derived full-spectrum oil. Intoxication is not the issue this number is about. Labeling honesty and drug-test risk are.
What is changing in late 2026?
Federal hemp rules are being rewritten toward a total-THC standard and a very small per-container cap. Dates have already moved once. Broad-spectrum, THC-free products are not what that cap is aimed at. Treat any deadline you read — including this one — as the current answer. We update as the law does.
