Can You Grow Cannabis in Texas? Penalties and Hemp License

Growing cannabis in Texas is illegal for personal use, whether recreational or medical. There is no home-grow allowance, no caregiver exception, and no carve-out for patients enrolled in the state’s medical program. The only legal way to cultivate a cannabis plant in Texas is to obtain a hemp producer license from the Texas Department of Agriculture and keep every plant below 0.3% delta-9 THC. Anything above that number is marijuana, and marijuana cultivation is prosecuted as felony possession once the plant material passes four ounces.

The 0.3% THC Line Decides Everything

Texas law splits the cannabis plant into two legal categories based on a single number. At or below 0.3% delta-9 THC on a dry weight basis, the plant is hemp and falls under the Agriculture Code. Above 0.3%, the same plant is “marihuana” under the Texas Controlled Substances Act, and possessing or growing it is a crime.¹

The statutory definition of marihuana covers the Cannabis sativa L. plant and its seeds along with any compound derived from it, and it explicitly excludes hemp, which the state defines separately.¹ The hemp framework itself came from House Bill 1325 in 2019, which authorized hemp production statewide under a licensing scheme run by the Texas Department of Agriculture.²

The practical consequence: if you plant a cannabis seed at home and the mature plant tests above 0.3% delta-9 THC, you do not have a legal hemp crop. You have marijuana, and your intent when you planted it is irrelevant to the charge.

Medical Patients Still Cannot Grow Their Own

This is the part that surprises people. Texas has a medical cannabis program, the Compassionate Use Program (TCUP), but it does not authorize any patient to cultivate a plant. All growing, processing, and dispensing is restricted to state-licensed dispensing organizations regulated by the Department of Public Safety.³

Only the patient (or a legal guardian) is protected from prosecution for possessing low-THC cannabis, and only when the product came from a licensed dispensing organization. There is no caregiver exception. Growing a single plant at home, even with an active TCUP prescription, falls outside the program’s protection and exposes the patient to the same criminal penalties as anyone else.³

What the Penalties Actually Look Like

Texas does not have a stand-alone cultivation offense. Growing marijuana is charged as possession under Section 481.121 of the Health and Safety Code, and the punishment is set by the aggregate weight of everything seized. That aggregate weight includes stems, roots, leaves, and wet plant material, not just the usable flower. A few plants in a closet can easily clear four ounces once soil-covered root balls and green biomass are on the scale, which is how a small personal grow ends up in state jail felony range.⁴

Two ounces or less: Class B misdemeanor, up to 180 days in jail and a fine up to $2,000.
More than two but no more than four ounces: Class A misdemeanor, up to one year in jail and a fine up to $4,000.⁵
More than four ounces but no more than five pounds: state jail felony, 180 days to two years in a state jail facility and a fine up to $10,000.
More than five pounds but no more than 50 pounds: third-degree felony, two to 10 years in prison and a fine up to $10,000.⁶
More than 50 pounds but no more than 2,000 pounds: second-degree felony, two to 20 years in prison and a fine up to $10,000.⁷
More than 2,000 pounds: first-degree felony, five to 99 years or life in prison and a fine up to $50,000.⁴

What Else a Conviction Costs

Jail time and fines are only the front end of the damage. Any conviction under the Controlled Substances Act triggers an automatic 90-day driver’s license suspension. Reinstatement requires a 15-hour drug education course, a $100 fee, and an SR-22 financial responsibility certificate maintained for two years. Skip the drug education course and the suspension extends indefinitely.⁸

A felony-level cultivation conviction (anything over four ounces of plant material) also bars firearm possession under federal law. 18 U.S.C. § 922(g) prohibits firearm possession by anyone convicted of a crime punishable by more than a year in prison, and the same statute separately bars any “unlawful user of or addicted to any controlled substance” from possessing a firearm, which reaches people who have never been convicted.⁹ The felon-in-possession ban is a lifetime prohibition absent a presidential pardon or Attorney General relief.

Professional licenses are also at risk. Texas licensing boards for healthcare workers, teachers, attorneys, and commercial drivers require applicants to disclose criminal history and can deny, suspend, or revoke a license based on a drug felony. And a felony controlled-substance conviction closes the one legal path to cannabis cultivation in Texas: federal hemp rules disqualify anyone with such a conviction from holding a hemp producer license for 10 years from the date of conviction.¹⁰

The One Legal Path: A Hemp Producer License

If you want to grow a cannabis plant legally in Texas, you have to grow hemp under a Texas Department of Agriculture license, and you have to accept both state and federal oversight of the crop.

Getting the License

Every prospective grower must watch an official TDA orientation video before applying. Applications go through the TDA eApply portal and must list at least one facility location. Once approved, the producer license arrives by email, but you cannot plant until you also obtain a Lot Crop Permit for the specific field or facility.¹¹

Federal rules add a criminal background check dated within 60 days of the application for every applicant or key participant in the business. A state or federal felony conviction involving a controlled substance disqualifies the applicant for 10 years from the conviction date, and falsifying anything on the application is a full disqualification.¹⁰

Testing and Hot Crops

Before harvest, a TDA-licensed sampler collects an official sample and sends it to a TDA-registered laboratory. Pass, and you can apply for a transport manifest. Fail, meaning the crop tests above 0.3% delta-9 THC, and you must destroy the crop and file a disposal report with TDA.¹¹ Lab testing typically runs between $75 and $750 per sample.

Federal Law Is Still in the Background

Cannabis remains a Schedule I controlled substance under federal law. A rescheduling process to move marijuana to Schedule III began in 2024, and a December 2025 presidential order directed the Attorney General to finalize the reschedule, but the process was still awaiting an administrative law hearing as of late 2025.¹² For Texans, the federal overlay bites hardest in two places: cultivation on federal land such as national forests and parks is a separate federal offense (up to a year in prison and a minimum $1,000 fine for a first conviction),¹³ and federal authorities can pursue asset forfeiture against homes, land, and vehicles connected to a grow.
