Is CBD Legal in Kansas? The 0.3% Total-THC Rule, Explained

Kansas Rules

We are a licensed Kansas hemp business, and we are going to start by correcting ourselves. An earlier version of this article told you the Kansas rule was genuinely unsettled and that we could not point you to a clean answer. That was honest at the time. It was also wrong — we had been reading what other CBD companies wrote about Kansas law instead of reading Kansas law.

So here is the statute.

Where the “Kansas is a zero-THC state” idea comes from

It comes from 2018, and it was true then.

Claire and Lola’s Law carved CBD out of the state’s definition of marijuana that year. The Kansas Attorney General followed with an opinion confirming that CBD containing no THC was lawful to possess and sell in Kansas. Both are real, and the marijuana carve-out is still on the books today.

But notice what that opinion answered. The question put to the Attorney General was specifically about CBD with no THC in it. He said yes. He was not asked, and did not say, that everything else was banned. Eight years later that answer is still circulating as though it were a ceiling, mostly on CBD retail blogs quoting each other.

What Kansas law says now

In 2019 Kansas passed the Commercial Industrial Hemp Act, and in 2021 amended it to add a sentence that answers the question directly. From K.S.A. 2-3901(b)(4):

Two words in that sentence do the work.

“Final.” The Kansas Attorney General, interpreting this same amendment in 2021, read “final hemp products” to mean products in a form suitable for sale to consumers. That is the jar on the shelf — exactly the thing people are asking about.

“Concentration.” The statute defines the term by cross-reference, and the definition covers THC and its optical isomers, their salts and acids, and the salts of those acids. In plain English: everything that is or becomes THC, added together. The Attorney General reached the same conclusion — the 0.3% is a total-THC figure, not a delta-9 figure.

That last point is the one worth carrying around. Federal law today still measures delta-9 alone. Kansas has measured total THC since 2021. Same number, tighter test — which means a product formulated to squeak under the federal line can still miss in Kansas.

Some products are banned in Kansas no matter what the lab says

This part gets left out of almost every article on the subject, and it catches more people than the percentage does. Kansas makes certain hemp products unlawful to manufacture, market, sell or distribute regardless of THC content:

• Cigarettes and cigars containing hemp
• Chew, dip and other smokeless material
• Teas
• Liquids, solids or gases for use in vaping devices

A zero-THC hemp vape is still not lawful to sell in Kansas. Neither is a hemp tea. If a shop is selling you one, the lab report is not the problem.

The practical way through

Here is the useful part: if a product contains no THC at all, none of the arithmetic applies to you. It clears the strictest reading and the loosest one at the same time, in Kansas and everywhere else.

That matters most in two situations people overlook:

• Buying while traveling. A product picked up in another state was probably formulated to the federal delta-9 standard, because that is the bigger market.
• Ordering online from out of state. Same issue, and the label rarely tells you which standard the maker had in mind.

In both cases the answer is the same: find the Certificate of Analysis for that batch and look at the THC line. If a seller cannot show you one, that is your answer.

What changes on November 12, 2026

Public Law 119-37 moves the federal measurement from delta-9 THC alone to total THC — catching the rest of the country up to where Kansas already is — and adds something genuinely new: a cap of 0.4 milligrams of total THC per container. Per container, not per serving. Products above that line stop being legally hemp.

The per-container cap is far tighter than any percentage, and it is the part worth checking a lab report over. We covered it in plain English here.

Where K61 sits

We are based in Hutchinson, and we build to zero rather than to the line — not because the line is unclear, but because zero is the only number that stays correct no matter which way the rules move next.

Our two topicals use CBD isolate: the CBD separated from everything else, so there is no THC to measure. Our gummies use broad spectrum extract, and our batch lab reports have come back non-detectable for THC.

Every batch report is published. Scan the QR code on the jar and read the one that matches your product — do not take our word for it. That instruction is the whole point of this article: the statute is public, the lab report is public, and you should not have to trust a seller’s summary of either.
