The Texas Department of State Health Services (DSHS) has officially adopted new hemp regulations that take effect on March 31, 2026. The rules fundamentally change how THC is calculated in hemp products and will effectively ban the retail sale of THCA flower, smokable hemp, and hemp-derived concentrates in Texas. If you're a consumer wondering what you can and can't buy after March 31, this guide breaks down every key change and what it means for you.
What Changed: The Total THC Rule
Under the original 2019 Texas hemp law, hemp products were legal as long as they contained no more than 0.3% Delta-9 THC by dry weight. The way labs tested for compliance measured only Delta-9 THC — not other cannabinoids. This is what made THCA flower legally compliant: the flower could contain 25–30% THCA while staying under 0.3% Delta-9 THC at the time of testing.
The new DSHS rules change this by requiring a "total THC" calculation that includes THCA in the Delta-9 THC measurement. Because THCA converts to THC when heated through smoking or vaping, DSHS now counts THCA toward the legal THC limit. Under this formula, a flower testing at 25% THCA has a calculated total THC content of approximately 22% — far above the 0.3% threshold.
The practical result: there is no compliant THCA flower product at natural potency levels under the new testing formula. Any hemp flower with meaningful THCA content will exceed the limit.
What's Banned After March 31, 2026
The following products can no longer be legally manufactured, distributed, or sold at retail in Texas after March 31:
THCA flower — All smokable hemp flower containing THCA above trace levels will exceed the total THC limit under the new calculation. This applies to loose flower, pre-rolls, and any product containing raw THCA flower.
THCA concentrates — Live badder, live rosin, hash, and other concentrates derived from THCA-rich hemp will also exceed the total THC limit.
THCA vapes — Live resin and other THCA-based vape products are affected by the same total THC calculation and will be non-compliant.
It's important to note that the DSHS rules govern the manufacture, distribution, and retail sale of these products in Texas. The rules do not directly address consumer possession of products purchased before March 31 or products purchased from out-of-state retailers.
What's Still Legal After March 31
Not all hemp products are affected. Products that were formulated around the Delta-9 THC dry-weight calculation — rather than relying on THCA content — remain compliant:
Delta 9 gummies and edibles — Hemp-derived Delta 9 gummies contain a measured dose of Delta-9 THC within a product heavy enough to stay below 0.3% by dry weight. A gummy weighing several grams with 10–20 mg of Delta-9 THC remains fully compliant because the THC concentration relative to total product weight is below the threshold. Gummies don't contain significant THCA, so the total THC calculation doesn't change their status.
THC beverages — Same principle as gummies. The product weight dilutes the THC concentration below legal limits.
CBD products — Products containing CBD with only trace amounts of THC are unaffected by the new rules.
Topicals, tinctures, and capsules — These products can continue to be sold as long as they meet the THC limits under the total THC standard.
New Licensing Fees
The new rules also introduce significantly higher licensing fees for Texas hemp businesses:
Manufacturer licenses: $10,000 per facility per year (up from approximately $258 under previous rules).
Retail registrations: $5,000 per location per year (up from $155 under previous rules).
These fees were reduced from the originally proposed amounts ($25,000 for manufacturers and $20,000 for retailers) after DSHS received over 1,400 public comments opposing the higher figures. The fees are intended to fund inspections, lab testing, enforcement, and agency coordination. Industry groups have argued that the fees are still high enough to force small operators out of business, particularly when combined with the loss of smokable products that many retailers depend on for a significant portion of their revenue.
Legal Challenges in Progress
The hemp industry is not accepting these rules quietly. Two legal fronts are developing:
The Texas Hemp Business Council has publicly stated that a lawsuit challenging the DSHS rules is forthcoming. The core legal argument is that DSHS exceeded its statutory authority by redefining "total THC" to include THCA — a change that the industry argues amounts to a legislative function that only the Texas Legislature can perform.
Separately, the Texas Supreme Court heard oral arguments in January 2026 in a related case (Sky Marketing v. DSHS) that questions whether DSHS can effectively reclassify hemp-derived cannabinoids through administrative rulemaking rather than legislation. A ruling is pending and could have implications for the new rules.
Whether any court issues an injunction before March 31 remains uncertain. Consumers and businesses should plan based on the assumption that the rules will take effect as scheduled while monitoring legal developments.
How This Connects to the Federal Situation
Texas isn't acting in a vacuum. At the federal level, Congress passed H.R. 5371 in November 2025, which rewrites the federal definition of hemp to include total THC (including THCA) and caps finished hemp products at 0.4 mg total THC per container. That federal law takes effect on November 12, 2026, creating a nationwide deadline that would affect hemp products in all 50 states. For a full breakdown of the federal situation, read our guide to the 2026 federal hemp changes.
The Texas DSHS rules effectively implement a similar total THC standard at the state level eight months ahead of the federal deadline. However, the federal law's 0.4 mg per container limit for finished products is far more restrictive than the Texas rules and would affect even Delta 9 gummies and edibles if enforced as written.
What This Means for The Haze Connect
The Haze Connect is based in Austin, Texas, and we're directly impacted by these changes. We believe in full transparency with our customers about the regulatory landscape.
Our Delta 9 gummies remain fully legal and compliant under both current Texas law and the new DSHS rules taking effect March 31. These products are formulated within the Delta-9 THC dry-weight limit and are unaffected by the total THC calculation change.
For customers in states where THCA flower, pre-rolls, vapes, and concentrates remain legal, our full product lineup continues to be available through our online store. We ship to all states where hemp-derived THCA products are currently permitted — check our state-by-state legality guide for current shipping availability.
We are monitoring the legal challenges to the DSHS rules, the pending Texas Supreme Court ruling, and federal legislative developments closely. We will update this page as the situation evolves.

Frequently Asked Questions
Can I still buy THCA flower online and have it shipped to Texas after March 31?
The DSHS rules govern the manufacture, distribution, and retail sale of hemp products within Texas. The legality of receiving shipments of products purchased from out-of-state retailers is a gray area that the rules do not directly address. Consumers should be aware that enforcement and interpretation may evolve, and we recommend following developments closely.
Are Delta 9 gummies still legal in Texas?
Yes. Hemp-derived Delta 9 gummies that contain less than 0.3% Delta-9 THC by dry weight remain fully compliant under both current Texas law and the new DSHS rules. Gummies do not contain significant THCA, so the total THC calculation does not change their compliance status.
Is it illegal to possess THCA flower in Texas after March 31?
The DSHS rules regulate businesses — manufacturers, distributors, and retailers. They do not directly create new criminal penalties for consumer possession. However, the legal landscape is complex, and consumers should understand that products exceeding the total THC limit may not qualify as legal hemp under the updated definitions.
Could a court block these rules before March 31?
It's possible. The Texas Hemp Business Council has announced plans to file a lawsuit, and a related case is pending before the Texas Supreme Court. However, there is no guarantee that any court will issue an injunction before the effective date. We recommend planning based on the assumption that the rules will take effect as scheduled.
