One case challenges the state’s authority to classify manufactured cannabinoids such as Delta-8 as controlled substances. Another argues Texas health agencies effectively rewrote the state’s hemp law through new testing standards and licensing fees.
Texas’ latest crackdown on intoxicating hemp has moved from rulemaking into two separate court fights.
The cases challenge different parts of the state’s new regulatory structure, involve different products and could produce very different outcomes.
One lawsuit targets the Texas Department of State Health Services’ renewed classification of commercially manufactured cannabinoids such as Delta-8 and Delta-10 as controlled substances.
The other challenges new consumable-hemp regulations affecting THCA flower, product testing and the cost of operating a hemp business in Texas.
Together, they will help determine not only what stores may continue selling, but whether products openly available for years can now expose businesses and consumers to criminal or financial penalties.
The disputes also raise a larger question:
How much power does a state agency have to close a loophole the Legislature left unresolved?
On July 31, DSHS reinstated language clarifying which forms of tetrahydrocannabinol are included on Texas’ controlled-substances schedule.
The change followed a May ruling from the Texas Supreme Court in Texas Department of State Health Services v. Sky Marketing Corp., the long-running case involving Austin-based hemp company Hometown Hero and other plaintiffs.
The court upheld DSHS’ authority to use the state’s administrative process to classify tetrahydrocannabinols and synthetic equivalents as controlled substances. The court later denied rehearing, clearing the way for the agency’s definitions to return.
DSHS published notice of the reinstatement in the July 10 edition of the Texas Register, with an effective date of July 31. The agency’s current controlled-substances page confirms that timeline.
The definitions apply to non-Delta-9 THC isomers and synthetic equivalents, including commercially manufactured products commonly marketed as Delta-8, Delta-10 and similar cannabinoids.
The hemp industry argues that many of those products were produced from federally lawful hemp and sold for years under the language of the 2018 Farm Bill and Texas’ 2019 hemp law.
Texas has taken the position that neither law required the state to permit manufacturers to chemically convert CBD into intoxicating THC analogues.
That disagreement is now before a federal court.
The federal lawsuit: Can Texas recriminalize hemp derivatives?
The first new case was filed in federal court shortly after the July 31 classifications became enforceable.
According to the complaint summarized in the research reviewed by The Directory, the plaintiffs include a Texas retailer, an out-of-state manufacturer and a Galveston County store manager. They are seeking to block enforcement of the state’s controlled-substance definitions.
Their argument rests on three principal claims.
Federal preemption
The plaintiffs argue that the 2018 Farm Bill removed hemp and its derivatives, extracts and isomers from the federal Controlled Substances Act when they contain no more than 0.3% Delta-9 THC by dry weight.
Under that theory, Texas cannot classify federally lawful hemp derivatives as Schedule I substances simply because they are intoxicating or produced through chemical conversion.
Texas is likely to answer that the Farm Bill established a federal definition of hemp but did not prevent states from adopting stricter rules governing production, possession or sale within their borders.
That argument has gained support in several federal appellate courts.
Courts reviewing restrictions in Arkansas, Virginia and Wyoming have generally concluded that states may impose rules stricter than the federal hemp baseline, including restrictions on synthetic cannabinoids and total THC content. Those rulings are not all binding on a federal judge in Texas, but they may be persuasive.
That makes the industry’s federal-preemption claim important—but far from certain to succeed.
Interstate commerce
The plaintiffs also argue that Texas is interfering with lawful interstate commerce by turning products manufactured and transported through a national hemp market into contraband once they enter the state.
Federal law protects the interstate transportation of hemp produced in compliance with an approved regulatory plan.
But that protection does not necessarily require a state to allow the retail possession or sale of every hemp-derived product once it arrives.
The legal question may therefore turn on whether Texas is regulating commerce within the state or effectively obstructing a federally protected national market.
Due process and fair notice
The lawsuit’s third major argument concerns notice.
Businesses invested in inventory, equipment, leases and supply agreements while Delta-8 and similar products were openly sold across Texas. The plaintiffs argue that the state has now transformed those products into felony contraband through administrative action rather than a new legislative vote.
Texas will likely respond that the products were never clearly legalized and that the industry continued operating while the state’s attempted classification was temporarily blocked by litigation.
The state can argue that the legal uncertainty was known for years.
The industry can answer that uncertainty is not the same as clear notice that lawful inventory would become a controlled substance on a specific date.
That issue may not determine whether Texas can prohibit the products, but it could affect how a court evaluates the fairness and timing of enforcement.
The second case targets THCA, testing rules and business fees
The federal lawsuit should not be confused with a separate case brought by the Texas Hemp Business Council and other industry plaintiffs in Travis County.
That case challenges regulations adopted by DSHS and the Texas Health and Human Services Commission governing consumable hemp products.
The challenged rules included a new “total THC” testing standard.
Rather than measuring only the amount of Delta-9 THC present in a raw product, the total THC formula also accounts for THCA—the non-intoxicating precursor that converts into Delta-9 THC when heated.
The research brief expresses the formula as:
Total THC = Delta-9 THC + a calculated portion of THCA.
That approach would cause much of the THCA flower sold as hemp to exceed Texas’ 0.3% limit, even when its unheated Delta-9 concentration remains below the statutory threshold.
The rules also substantially increased annual licensing costs, with manufacturer licenses rising to $10,000 and retail registrations to $5,000 per location.
The industry plaintiffs argue that the agencies did not merely administer the hemp law.
They argue the agencies rewrote it.
Their lawsuit contends that the Legislature defined legal hemp using Delta-9 concentration and did not authorize regulators to replace that standard with a broader total THC calculation or impose fee increases disconnected from the statute.
A Travis County court granted temporary relief blocking key provisions while the litigation continues. The case has since moved through an appellate fight over whether that injunction should remain in place.
As a result, the status of THCA flower and other products affected by the total THC rules is not identical to the status of commercially manufactured Delta-8 and Delta-10 products.
That distinction is important.
Two lawsuits, two different legal tracks
Texas’ hemp rules are now divided into two broad categories.
Manufactured THC isomers
Commercially produced Delta-8, Delta-10 and similar non-Delta-9 cannabinoids fall under the restored controlled-substance definitions that became effective July 31.
The federal lawsuit seeks to stop that criminal classification.
Consumable-hemp regulations
THCA testing, smokable hemp restrictions and major licensing-fee increases are being contested in the Travis County case.
Those provisions involve administrative and commercial regulation rather than precisely the same Schedule I classification challenged in federal court.
The products may look similar on a store shelf, but the legal questions are different.
One case asks whether Texas can classify certain hemp-derived cannabinoids as controlled substances.
The other asks whether state agencies exceeded their delegated authority when regulating products that may still fall within the Legislature’s definition of hemp.
Why the distinction matters for consumers
For businesses, the immediate concern is inventory.
For consumers, the stakes may be much more serious.
Once a substance falls within Texas’ controlled-substance schedules, possession is no longer simply a licensing or retail violation. It can create criminal exposure.
Under the framework described in the research brief, possession of less than one gram of a covered THC concentrate may be prosecuted as a state-jail felony, carrying a potential sentence of 180 days to two years and a fine of up to $10,000. Higher weights can produce more serious felony ranges.
That does not mean every person found with a Delta-8 gummy will receive a prison sentence. Police, prosecutors and courts retain discretion, and the state must still prove the identity and weight of the prohibited substance. But felony exposure matters even when the maximum sentence is rarely imposed.
An arrest, indictment or felony conviction can affect employment, housing, professional licensing, firearm rights and a person’s future long after the product itself has been consumed.
It also creates a difficult proportionality question.
Texas law can expose a nonviolent possessor of certain THC concentrates to years of incarceration, while defendants in cases involving much more harmful conduct sometimes receive shorter sentences through negotiated pleas.
Those cases are not legally identical, and statutory maximums should not be casually compared with the result of an individual plea bargain.
Still, the contrast illustrates how aggressively Texas continues to use felony law against drug possession.
The state has a legitimate interest in regulating intoxicating products, protecting children and preventing mislabeled or contaminated substances from reaching consumers.
The policy question is whether that goal requires treating possession as a felony—or whether testing, packaging, age restrictions, taxation and licensed sales could address the public-health concerns more proportionately.
The state’s public-health argument
Texas is not acting without evidence of harm.
State officials have pointed to rising poison-control calls and pediatric exposures involving THC products, including gummies and other products that may resemble ordinary candy.
The research reviewed by The Directory cites more than 10,000 THC-related exposure calls from 2021 through May 2026, including thousands involving children and teenagers. It also identifies hundreds of cases categorized as producing major clinical effects.
Those numbers support stronger regulation.
They do not necessarily settle what form that regulation should take.
The state may argue that the existing market grew around products never contemplated by lawmakers, often with inconsistent testing, attractive packaging and limited age controls.
The industry may respond that those risks justify a regulated adult market rather than prohibition.
Both positions begin with the same underlying fact: Texas’ 2019 hemp law opened a commercial market faster than the state developed a coherent system for governing intoxicating products within it.
The courts are now being asked to resolve consequences the Legislature repeatedly struggled to settle.
Enforcement may vary by county
Even if Texas ultimately wins both lawsuits, enforcing the new rules may be difficult.
Hemp-derived products and illegal marijuana concentrates can appear identical.
Determining whether a gummy, vape liquid or flower product contains a prohibited isomer may require laboratory testing capable of separating closely related cannabinoids and measuring their concentration. Texas crime laboratories have faced testing limits since hemp was legalized in 2019. That has already contributed to uneven marijuana enforcement across the state.
Some counties may prioritize small possession cases.
Others may focus on manufacturers, distributors and retailers.
Still others may avoid prosecution unless the amount or surrounding circumstances justify the cost of laboratory confirmation.
That means the practical meaning of the new rules could depend heavily on where a person is stopped and which prosecutor controls the case.
A substance can be prohibited statewide while enforcement remains inconsistent locally.
The hemp conflict did not appear overnight.
Congress legalized hemp in 2018 using a Delta-9 threshold that proved poorly suited to the chemistry of finished intoxicating products.
Texas adopted similar language in 2019.
Manufacturers then developed a large commercial market around cannabinoids that could produce intoxicating effects while remaining outside a narrow reading of the Delta-9 limit.
DSHS attempted to classify Delta-8 in 2021.
The industry sued and operated under an injunction for years.
The Legislature later attempted to pass a broader prohibition, but Gov. Greg Abbott vetoed the measure and directed agencies to pursue a regulatory alternative.
The Texas Supreme Court then cleared the way for the older DSHS definitions to return.
Each branch of government has touched the issue.
None has produced lasting clarity.
The result is a system in which one product may be criminally prohibited, another may remain available because of an injunction, and a third may be lawful only if a laboratory calculation falls below a threshold most consumers cannot independently verify.
That is not a stable regulatory framework.
What the courts could decide
The federal case could determine:
- Whether the Farm Bill prevents Texas from classifying certain hemp derivatives as controlled substances;
- Whether the state’s rules improperly burden interstate commerce;
- Whether businesses and consumers received adequate notice;
- And whether enforcement can continue while the case proceeds.
The Travis County case could determine:
- Whether DSHS may use total THC rather than Delta-9 alone;
- Whether the agencies had authority to impose the new fees;
- Whether THCA flower and other products remain within Texas’ statutory definition of hemp;
- And how much freedom regulators have to close perceived loopholes without returning to the Legislature.
Neither case is simply about whether intoxicating hemp is good or bad.
The question before the courts is who has the legal authority to decide.
The Texas lawsuits are also unfolding against a changing federal backdrop.
A federal law scheduled to take effect in November 2026 would narrow the national definition of hemp, adopt a total THC framework, exclude certain manufactured cannabinoids, and impose a much lower finished-product THC limit.
That could eliminate much of the legal foundation supporting the current intoxicating-hemp market regardless of how the Texas cases conclude.
But the state lawsuits still matter.
They will determine what Texas may enforce before the federal changes take effect, whether businesses receive relief for the remaining period and how courts understand agency authority when a rapidly changing industry grows inside ambiguous statutory language.
They may also shape future disputes involving other products whose chemistry evolves faster than the Legislature’s definitions.
The larger dispute
The hemp industry benefited from a loophole. That does not mean every method of closing it is lawful.
Texas has legitimate reasons to regulate intoxicating products, prevent sales to minors and require accurate testing. That does not automatically answer whether an agency can convert products sold openly for years into felony contraband without new legislation.
The industry has legitimate financial interests. That does not automatically give it a constitutional right to continue selling every product Congress or Texas once failed to regulate clearly.
Those are the questions the lawsuits must separate.
The courts will decide whether Texas followed the law when it changed the rules.
The public must decide whether the punishment fits the conduct.
The lawsuits may determine what Texas can prohibit. The larger debate is about whom Texas is willing to prosecute and how much warning government owes before yesterday’s retail product becomes today’s felony evidence.
