Last Day to Buy: Texas Bans Smokable Hemp & THCA Flower Starting Today
By The ATX Aggregator
Today marks the end of an era for Texas’s booming hemp retail industry.
New regulations adopted by the Texas Department of State Health Services (DSHS) take effect this morning, effectively banning the retail sale of smokable hemp, THCA flower, pre-rolled joints, live resin, and hemp-derived concentrates — a product category that has exploded across Austin and the state since 2019.
The rules, finalized on March 2 and published in the Texas Register on March 20, follow Governor Greg Abbott’s Executive Order GA-56, signed in September 2025, which directed DSHS and other state agencies to tighten the state’s consumable hemp program. The result is a sweeping regulatory overhaul that the industry says amounts to an outright ban dressed up as rulemaking.
The THCA Loophole — How We Got Here
To understand today’s crackdown, you have to go back to 2019, when the Texas Legislature legalized hemp under House Bill 1325, defining it as cannabis containing no more than 0.3% Delta-9 THC by dry weight. That definition created an opening that entrepreneurs were quick to exploit.
Retailers discovered that THCA — tetrahydrocannabinolic acid, a non-psychoactive compound found naturally in cannabis — converts to Delta-9 THC when heated. A plant could carry 25–30% THCA while technically testing below the 0.3% Delta-9 threshold, because labs at the time measured only Delta-9 at the time of testing, not after combustion. Hemp shops began stocking shelves with what looked, smelled, and smoked exactly like marijuana — legally.
“Many lawmakers have said this legal loophole allowed a recreational THC market to appear overnight without direct approval from the state,” reported KERA News, summarizing the legislative frustration that fueled years of attempted crackdowns.
The new DSHS rules close the loophole by requiring a “total THC” calculation that adds THCA to the Delta-9 measurement. Under that formula, virtually any THCA flower fails the 0.3% test — and is now off-limits to sell in Texas.
A Messy Path Through the Legislature
The road to today’s ban was anything but straight. The Texas Legislature passed Senate Bill 3 during the 89th Session, which would have banned most hemp-derived THC products outright. Abbott vetoed it. Legislative efforts in two subsequent special sessions stalled, consumed by redistricting battles. That left Abbott to act through executive order, directing agencies to accomplish through regulation what the Legislature could not pass through statute.
Texas had already banned all hemp vape products in September 2025 under SB 2024, signed by Abbott in June of that year. Today’s rules go further, sweeping up the smokable and extract categories that survived the vape ban.
What Changes — and What Doesn’t
Delta-9 THC edibles (gummies, chocolates) that stay under the 0.3% threshold remain legal. CBD products, tinctures, and topicals are unaffected. The rules govern manufacturers, distributors, and retailers — not personal possession — though attorneys warn about enforcement confusion on the streets.
Tomorrow, Texas will push more consumers toward the black market by further restricting access to regulated hemp products.

These rules won’t reduce demand—they’ll shut down businesses and limit access to legal, tested options.
Instead of generating tax revenue, illegal markets…
The regulatory changes also include dramatically higher licensing fees. Manufacturer licenses jump from $258 to $10,000 per facility; retail registrations climb from $155 to $5,000. Industry leaders say those increases alone will shutter dozens of smaller shops.
Industry Reaction: “Death By a Thousand Paper Cuts”
Austin-area hemp retailers have spent the last two weeks in a frantic clearance mode. “We are still running a sale, trying to burn out the stuff that’s no longer going to be available,” Kenneth Berner, co-owner of Burners Vape, Smoke and Herb in the Houston area, told Houston Public Media. “And that’s going to happen ‘til the end of the day, and then whatever’s left at closing time will get boxed up.”
Lukas Gilkey, CEO of Austin-based Hometown Hero — one of the state’s largest hemp manufacturers — did not mince words. “They did a ban with their own regulatory scheme,” he told the Texas Tribune and KERA News. He added: “The problem is that the desire for these products is not going to go away; they will just order them online, where it’s still legal, or off the street, where we have no testing and no guidance.”
Smaller operators face an existential choice. Luke Temple, owner of T&T Roots — who cultivates, manufactures, and retails hemp — told Spectrum News that smokable flower will have to be shipped out of state, while he hopes edibles and tinctures can sustain the business. “Our dream was to come back to Texas and use what we learned over the years to Texas and the people of Texas,” said his head of cultivation, Jeremy Brewer. “It hurts.”
Texas is set to ban retail sale of hemp flower Tuesday, March 31st ensuring massive profits to New Mexico, Colorado, and Missouri rec sales. Overnight Texas will reestablish the biggest cannabis black market in the country and cannabis arrests will once again skyrocket to lead…

Austin Zamhariri, executive director of the Texas Cannabis Collective, warned that pivoting to industrial hemp cultivation is not a realistic escape hatch. “The migration would be too catastrophic for most businesses to sustain,” he said.
Legal Challenges Already in Motion
The hemp industry is not going quietly. Two separate legal fronts are active, and either could unravel the new rules:
The Texas Hemp Business Council lawsuit. The Council has publicly signaled that a legal challenge is imminent, with a request for an injunction expected imminently. The core argument: DSHS exceeded its statutory authority by redefining “total THC” to include THCA — a change that the industry contends is a legislative function that only the Texas Legislature, not a state agency, can perform.
Sky Marketing Corp. v. DSHS (the Hometown Hero case). This older lawsuit — dating to 2021, when DSHS tried to classify Delta-8 THC as a Schedule I substance via a website notice — has already wound its way to the Texas Supreme Court, which heard oral arguments in January 2026. The central question is whether DSHS can effectively reclassify hemp-derived cannabinoids through administrative rulemaking, or whether that authority belongs exclusively to the Legislature. A ruling is pending. If the Supreme Court sides with the hemp industry, the legal reasoning could directly undermine the new March 31 rules.
Houston attorney Andrea Steel, who represents several THC businesses, raised a different concern: even if consumers are technically not targeted by the new rules, law enforcement on the ground may not distinguish between smokable hemp and marijuana.
Industry advocates also worry about pushing consumers toward unregulated channels. “We’re concerned that by restricting businesses and not allowing them to sell these products, we’re going to be sending consumers to the illicit market where there are no age restrictions, product safety standards, or consumer protections,” said Chloe Fazio, a hemp policy attorney.
A Federal Clock Is Also Ticking
Texas is not acting in a vacuum. Federal legislation (H.R. 5371) is set to take effect November 12, 2026, imposing nationwide restrictions on hemp-derived THC products — including a 0.4mg per-container limit that would affect even legal Delta-9 gummies. Texas’s DSHS rules arrive eight months ahead of that federal deadline. If the federal law takes full effect, winning the Texas court battle would be, at best, a temporary reprieve.
What Austin Consumers Should Know Today
If you purchased THCA flower or concentrates before today, you are not directly targeted by the DSHS rules — which regulate sellers, not buyers. However, law enforcement confusion remains a real risk for anyone smoking hemp in public. Delta-9 gummies, CBD products, and hemp edibles remain on store shelves. Online purchases from out-of-state retailers occupy a legal gray zone the rules do not directly address.
For retailers, the curtain comes down at midnight. Whatever smokable or extract inventory remains unsold tonight cannot legally be sold to Texas customers — only held, or shipped out of state.
The courts may yet intervene. But for today, Austin’s hemp shops are closing a chapter — and preparing to fight for the next one.
