THCA ban: what changes on Dec. 11, 2026, what stays legal and what buyers can do until then
THCA flower stays federal hemp through Dec. 10, 2026, if its delta-9 THC is 0.3 percent or less. What the statute changes on Dec. 11, what remains legal after it, and a buyer's checklist for the weeks in between, checked Oct. 21.

The short answer. As of Oct. 21, 2026, THCA flower is federal hemp through Dec. 10 if its delta-9 THC is no more than 0.3 percent of dry weight. On Dec. 11, 2026, Section 781 of Public Law 119-37 starts counting THCA, and high-THCA flower becomes marijuana under federal law. Until then, buyers can order where their state allows it.
The running record of every date and bill is our Hemp Ban Tracker, and the questions that start on Dec. 11 are answered in What happens to THCA after December 11. This page is for readers deciding what to do in the seven weeks before it.
What does the THCA ban change on Dec. 11, 2026?
It changes the one number that made THCA flower hemp. Today’s definition, from the 2018 Farm Bill, counts only “delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis” (7 U.S.C. 1639o). THCA is not delta-9 THC until heat converts it, so flower rich in THCA and low in delta-9 has passed.
Section 781 replaces that wording. Hemp becomes cannabis “with a total tetrahydrocannabinols concentration (including tetrahydrocannabinolic acid) of not more than 0.3 percent on a dry weight basis” (P.L. 119-37, sec. 781). Flower sold as THCA flower is, by its nature, high in THCA, so it fails that test.
| Through Dec. 10, 2026 | From Dec. 11, 2026 | |
|---|---|---|
| What the hemp limit measures | Delta-9 THC only | Total THC, “including tetrahydrocannabinolic acid” |
| Limit | 0.3% of dry weight | 0.3% of dry weight |
| High-THCA flower, federally | Hemp, if delta-9 is 0.3% or less | Marijuana |
| Final hemp products | No per-container THC cap | No more than 0.4 mg total THC per container |
| Cannabinoids “synthesized or manufactured outside the plant” | Not addressed for plant cannabinoids | Excluded from hemp |
The law was signed on Nov. 12, 2025, and Section 781 says it takes effect “365 days after the enactment of this Act.” H.R. 6500, signed Sept. 2, 2026, as Public Law 119-103, then limited that first date: until Dec. 11, the new definition applies only to products with cannabinoids “not capable of being naturally produced by a Cannabis sativa L. plant” (H.R. 6500, sec. 2019). Everything else, THCA flower included, moves on Dec. 11.
Outside the hemp definition, the plant is marijuana under the Controlled Substances Act, which excludes only “hemp, as defined in section 1639o of title 7” (21 U.S.C. 802(16)).
Is THCA still legal to buy before Dec. 11?
Under federal law, yes, through Dec. 10, as long as the flower meets today’s delta-9 limit. The federal definition does not change until Dec. 11, and nothing in Section 781 or H.R. 6500 brings that date forward for plant-grown cannabinoids.
State law is a separate question, and it is where most buyers are actually stopped. Many states already restrict or bar high-THCA flower under their own statutes and rules, and those limits apply now, whatever federal law says. Each State Page on this site gives your state’s rule with the statute and the date it was checked; all 51 are compared in one table at Is THCA legal?.
What stays legal after Dec. 11?
Three things remain hemp under the new text, as of Oct. 21, 2026:
| What | Why it stays legal | Where in sec. 781 |
|---|---|---|
| Hemp at or below 0.3% total THC, THCA counted | Meets the new definition | New 7 U.S.C. 1639o(1)(A) |
| Final hemp products with 0.4 mg or less of total THC per container | Under the cap | New 1639o(1)(C)(iv)(III) |
| Industrial hemp: stalk and fiber, grain, seed oil and cake, microgreens, research plants | Named as included in hemp | New 1639o(1)(B) and (2) |
Two open points. The law told the FDA to publish lists of cannabinoids and more detail on “container” within 90 days of enactment; the desk found none in the Federal Register as of Oct. 21. Without it, how the 0.4 mg cap applies to raw flower is not settled. For high-THCA flower the point is moot, because it fails the 0.3 percent definition first.
State-licensed marijuana stores do not depend on the hemp definition. Where a state licenses them, they sell high-THC flower under state law before and after Dec. 11; federal law has always classed that flower as marijuana.
Is there a grace period for THCA flower bought before Dec. 11?
Not in the statute. The desk read Section 781 and Section 2019 of H.R. 6500 again on Oct. 21, 2026. Neither contains a grandfather clause for flower already bought, a sell-through period for sellers, or an exception for packages still in transit.
Two practical consequences follow. A package delivered on or after Dec. 11 contains marijuana under federal law, whenever it was ordered. And flower kept at home after Dec. 11 is, federally, the same as flower bought that day. How your state treats possession is on your State Page; the possession and in-transit questions are worked through in What happens to THCA after December 11.
What can buyers do before Dec. 11?
| Step | Why it matters |
|---|---|
| Check your State Page first | State limits apply now, independently of the federal date |
| Order with time to spare | No transit exception: delivery has to be complete before Dec. 11 |
| Ask for the lot’s certificate of analysis | Shows the delta-9 line the current federal rule reads; see how to read a COA |
| Buy a size you will use | Flower kept past Dec. 10 has no federal hemp status |
| Be 21 or older | This site sells only to adults 21 and over |
On this menu the sizes run from the ounce to the pound. As of today’s menu, 78 lots are in stock, with half pounds from $235 and pounds from $425; the lowest works out to about $27 per ounce of flower, and a single ounce starts at $40. Two in-stock examples: Pineapple Express, indoor and Modified Sunset, light-dep. Lab values are not yet printed on product pages; ask for any Batch’s certificate of analysis in the note on your Order Request or by writing in, and it is sent by email.
How does ordering work on this site?
Three steps, and no money changes hands on the website:
- Choose. Put ounces, quarter pounds, half pounds or pounds from the menu in your cart.
- Send an Order Request. Leave your name, phone number, email, delivery address and how you would prefer to pay: cash, Zelle, Cash App, Venmo, card or something else. The preference is a note, not a charge.
- Confirm. We may call to confirm the order and check it against stock; payment, carrier and timing are agreed after that. A shipped order goes out once payment is settled.
Shipping is free. Every sale is final and returns are not accepted, which is why the order is confirmed before payment. The full terms are on How ordering and delivery work. With Dec. 11 fixed in law, put the date you need delivery by in the note on your Order Request, so timing is settled before you pay.
Could Congress move the Dec. 11 date?
It could, and nothing has moved yet. As of Oct. 21, 2026, H.R. 7024, which would change Section 781’s “365 days” to “3 years,” and H.R. 6209, which would repeal Section 781, both sit in House Agriculture subcommittees with no committee or floor vote, according to Congress.gov. The government’s stopgap funding also runs out on Dec. 11 (H.R. 6500, sec. 106), so the next spending bill is the likeliest vehicle for any change. Buyers should plan on the date in force. The tracker logs any change.

Questions readers asked
What does the THCA ban change on Dec. 11, 2026?
Section 781 of Public Law 119-37 redefines hemp by total THC, including THCA, at 0.3 percent of dry weight. High-THCA flower fails that test, so from Dec. 11, 2026 it is marijuana under federal law. Final hemp products are also capped at 0.4 mg of total THC per container, as of Oct. 21, 2026.
Is THCA still legal to buy before Dec. 11?
Under federal law, yes, through Dec. 10, 2026, if the flower's delta-9 THC is no more than 0.3 percent of dry weight. State law is separate and many states already restrict THCA flower, so check your State Page before you order.
What stays legal after Dec. 11?
Hemp at or below 0.3 percent total THC, THCA included; final hemp products with no more than 0.4 mg of total THC per container; and industrial hemp grown for fiber, grain, seed oil and similar uses, as of the law in force Oct. 21, 2026. State-licensed marijuana stores are not governed by the hemp definition.
Is there a grace period for THCA flower bought before Dec. 11?
Not in the statute. The texts of Section 781 and of Section 2019 of H.R. 6500 contain no grandfather clause, sell-through period or exception for packages in transit, as read by the desk on Oct. 21, 2026.
What can buyers do before Dec. 11?
Check your state's rule first, order early enough that delivery is complete before Dec. 11, ask for the certificate of analysis of the lot you choose, and buy a size you will use. On this menu that means anything from an ounce to a pound.
How does ordering work on this site?
You send an Order Request from the menu with your contact details and how you would prefer to pay. Nothing is charged online. We may call to confirm the order, and payment and delivery are arranged after it is confirmed. Shipping is free, and every sale is final.
Could Congress move the Dec. 11 date?
It could, but as of Oct. 21, 2026, neither H.R. 7024, which would delay Section 781, nor H.R. 6209, which would repeal it, has had a committee or floor vote, according to Congress.gov. Federal stopgap funding also ends Dec. 11, so a spending bill is the likeliest vehicle.
