Texas Hemp Industry Sues to Block THCA Ban. But Can the State Actually Stop Online Sales?

Texas hemp businesses filed suit in state court on Tuesday seeking a temporary restraining order against the rules that went into effect March 31 — the same rules that effectively banned smokeable THCA products across the state. The coalition behind the lawsuit argues that Texas regulators rewrote a definition that only the legislature has the power to change.

That’s a legitimate legal dispute, and the courts will work through it. But the lawsuit is actually the second-most interesting story coming out of Texas right now — and for the many Texans now wondering where hemp products stand across the country, the answer keeps changing.

The first is this: the state says out-of-state sellers who ship THCA products directly to Texas consumers are also violating the new rules. Cannabis attorneys aren’t buying it — and enforcement is, by any measure, nonexistent.

What the New Rules Actually Say

When the Texas Department of State Health Services (DSHS) adopted new regulations on consumable hemp in March, the headline change was the shift to “total THC” testing. Under the old standard, a product was legal if it contained less than 0.3% delta-9 THC. Under the new rules, labs must measure THCA — a non-intoxicating cannabinoid that converts to delta-9 when heated — as 88% delta-9 equivalent. Do the math and virtually every smokeable hemp product fails.

But the rules didn’t just apply to products on store shelves. According to DSHS, they apply to any product “introduced into commerce in this state” — and the agency’s position is that this includes items shipped directly to consumers.

“There is no carve out for mail order,” DSHS spokesperson Lara Anton told KUT News.

The Online Sales Question

Here’s the problem with that position: federal law.

The 2018 Farm Bill, which legalized hemp nationally, includes an explicit provision prohibiting states from interfering with the interstate transportation or shipment of hemp. That provision was designed specifically to prevent patchwork state laws from making it impossible to legally move hemp across state lines — a problem that plagued the early hemp farming industry.

Hemp-derived THCA, as cultivated from federally compliant hemp plants (not synthetically produced), falls under that Farm Bill framework. If a product is legal under federal standards at the point of origin, the argument goes, a state cannot prohibit its shipment to consumers.

“I would venture to say that anybody who is wanting to place an order for a product that will no longer comply with the new rules will probably not have any qualms finding a company to ship it to them from out of state,” said Andrea Steel, a cannabis attorney with The Banks Law Firm in Houston, speaking to KUT News.

Susan Hays, a veteran cannabis attorney and lobbyist, put it more plainly: “Whether anyone can be criminally prosecuted for buying products from out of state is still going to be doubtful and difficult. Most prosecutors, many cops, certainly the majority of the people living in Texas are over this idea of criminalizing a plant.”

The practical reality lines up with the legal skepticism. The Texas Department of Public Safety, which tests cannabis for law enforcement agencies, did not respond to requests for comment on how it plans to address online shipments. Austin police, for their part, told KUT that their enforcement approach hasn’t changed — and that officers rely on product packaging, not chemical testing, to distinguish hemp from marijuana. If you have packaging showing delta-9 THC content under 0.3%, Austin PD won’t confiscate it.

The Lawsuit: What It Argues

The coalition of hemp businesses — including the Texas Hemp Business Council, Hemp Industry & Farmers of America, and several Texas dispensaries and manufacturers — is making a narrower argument than the online sales debate. They’re not claiming the state has no power to regulate hemp. They’re arguing that DSHS overstepped the bounds of administrative authority.

Under Texas law, hemp is defined by its delta-9 THC concentration. The legislature set that standard in 2019. DSHS, the coalition argues, is not empowered to effectively change that definition by adopting a total-THC testing methodology — even if the regulatory intent is the same.

“Under current Texas law, hemp is defined by its delta-9 THC concentration of not more than 0.3%,” said David Sergi, an attorney for the coalition. “These Texas officials and state agencies are clearly attempting to create new law in direct contradiction to what the Texas legislature intended.”

It’s worth noting what the lawsuit isn’t challenging. The industry has accepted the new age verification requirements, the child-resistant packaging mandates, the labeling and bookkeeping requirements. The specific targets of the suit are the total-THC testing standard and the licensing fee increases — from $150 to $5,000 per location for retailers, and from $250 to $10,000 per year for manufacturers.

The fee increases are substantial enough on their own. For context, alcohol distillers in Texas pay $3,000 to the Texas Alcoholic Beverage Commission every two years. Hemp retailers are now paying more than three times that, annually, per location.

The Grey Zone Isn’t Going Away

Even if the lawsuit succeeds and a court reinstates the delta-9-only testing standard, the underlying legal conflict doesn’t resolve. Texas smokeable THCA products would be back on shelves. But the question of what happens after November 2026 — when the federal hemp definition itself changes — would still be unanswered.

Congress rewrote the federal definition of hemp last year, setting a November 12, 2026 deadline after which products exceeding 0.4 milligrams of total THC per container face federal prohibition. That federal change doesn’t depend on Texas’s state rules. It’s a separate clock, running in parallel.

So Texas hemp businesses are currently facing three overlapping legal frameworks simultaneously: state regulations that may or may not survive a court challenge, a federal Farm Bill preemption that may or may not protect online sales, and a federal regulatory cliff arriving in seven months.

For retailers, the operational question is the most immediate: do you clear your smokeable inventory, try to comply with the new rules, or wait for the courts? For consumers, the question is simpler: can you still get THCA products shipped to Texas?

Based on the current state of enforcement, the honest answer is: probably yes, for now. Whether that remains true depends on how courts handle the lawsuit, how federal agencies interpret their own rules, and whether Texas prosecutors develop any appetite for pursuing online orders — which, at the moment, they show no signs of doing.

That’s a grey zone in the truest sense. Three legal frameworks. No clear answer. And a deadline that’s getting closer every month.
