A broad Texas ban on hemp-derived THC products took effect July 31, placing delta-8, delta-10, THCP and similar manufactured compounds under the state’s controlled-substance rules.
The change came from the Texas Department of State Health Services’ reinstatement of definitions first adopted in 2021. The Texas Supreme Court’s May 1 ruling overturned an injunction that had blocked those definitions for years. The court issued its mandate June 5, allowing DSHS to reinstate them.
What is now prohibited
The reinstated definitions cover synthetic equivalents, derivatives and isomers with chemical structures and pharmacological activity similar to THC found in cannabis. They preserve the statutory exception for hemp containing no more than 0.3% delta-9 THC by dry weight.
In practice, the definitions reach many products sold by smoke shops and hemp retailers, including delta-8 gummies, delta-10 edibles and THCP products. Many of those compounds are manufactured by chemically converting CBD into other cannabinoids.
Possession of a controlled substance placed on the schedule by the commissioner but not assigned to another penalty group can be prosecuted as a state jail felony. The offense carries 180 days to two years in a state jail and a fine of up to $10,000.
Businesses that sell covered products also could face licensing, civil and criminal consequences. DSHS has advised that products labeled as containing delta-8, or products shown to contain more than naturally occurring trace amounts of THC isomers, may be detained and referred to law enforcement.
What remains legal
Delta-9 THC products remain legal under Texas hemp law when the finished product contains no more than 0.3% delta-9 THC by dry weight. Qualifying delta-9 edibles, beverages and tinctures therefore remain available, even though some can be intoxicating.
DSHS says only trace amounts of delta-8 THC naturally produced by the hemp plant are permissible. Manufactured delta-8 and similar compounds are the focus of the reinstated definitions.
Sales of consumable hemp products to people younger than 21 are prohibited under rules adopted after Gov. Greg Abbott issued Executive Order GA-56 in September 2025.
Vape products are subject to a separate law. Senate Bill 2024 made it a Class A misdemeanor to market, sell or offer an electronic cigarette product containing or marketed as containing cannabinoids. That law took effect Sept. 1, 2025.
Texas marijuana possession law did not change
The new THC rules did not change Texas’ marijuana possession statute. Texas Health and Safety Code Chapter 481.121 still establishes penalties based on the weight of marijuana possessed.
- Possession of 2 ounces or less is a Class B misdemeanor punishable by up to 180 days in county jail and a fine of up to $2,000.
- Possession of more than 2 ounces and up to 4 ounces is a Class A misdemeanor.
- Possession of more than 4 ounces is a felony, with penalties increasing according to weight.
A drug conviction can also result in a six-month driver’s license suspension.
THC concentrates generally are treated more harshly than marijuana flower. They typically fall under Penalty Group 2, where possession of less than 1 gram is a state jail felony.
The legal threshold separating hemp from marijuana remains 0.3% delta-9 THC by dry weight.
Smokable hemp flower remains unsettled
Smokable hemp flower is subject to a separate and less settled legal dispute. DSHS rules adopted this year changed how total THC is calculated. Under the formula, THCA counts toward the limit based on its potential conversion to delta-9 THC when heated.
The calculation could remove much of the high-THCA smokable hemp flower and pre-roll market. The rule took effect March 31, was blocked by a Travis County judge in May and later was allowed to take effect while litigation continued.
Questions remain about enforcement and how specific products are tested and labeled. The legal status of a product can depend on its composition, testing and labeling, and some legal accounts have treated THCA flower as part of the July 31 change while others have tied it primarily to the separate litigation.
The same regulatory litigation involved higher industry fees. DSHS currently lists consumable hemp product licenses at $10,000 annually per location and retail registrations at $5,000 annually per location, in addition to online fees.
How the change happened
Texas legalized hemp in 2019 and created the state’s consumable-hemp market. Retailers then built businesses around delta-8 and other compounds that state law did not specifically name.
DSHS expanded its controlled-substance definitions in October 2021. Austin retailer Hometown Hero and other plaintiffs sued and obtained an injunction that remained in place until the Texas Supreme Court’s 2026 ruling.
Lawmakers also tried to address the issue through legislation. Senate Bill 3 would have banned hemp-derived THC products in 2025, but Abbott vetoed it and called for regulation instead. Two special sessions followed without passage of a major hemp bill.
DSHS published the reinstatement notice July 10, and the definitions took effect July 31.
What comes next
Federal changes could further alter the market. Section 781 of H.R. 5371, signed in November 2025, changes the federal definition of hemp to exclude products with intoxicating levels of THC. That provision is scheduled to take effect Nov. 12, 2026, and could affect some products that remain legal in Texas.
The Texas Legislature returns Jan. 12. Lt. Gov. Dan Patrick has directed a Senate committee to study THC and its effects on health care costs, mental-health detentions and psychosis diagnoses.
Additional industry litigation is expected, so the legal boundaries for some hemp products could continue to change.
