Cannabis is broadly illegal under Texas cannabis laws, with two narrow carve-outs: a restricted medical program for qualifying patients and hemp products that stay under 0.3% delta-9 THC by dry weight. Everything else carries criminal penalties, and those penalties change dramatically depending on whether you have plant material or a concentrate like a vape cartridge.
Possession of Marijuana Flower
Possessing any usable amount of marijuana is a crime unless you are covered by the Compassionate Use Act. Penalties climb with weight.1State of Texas. Texas Health and Safety Code Section 481.121 – Offense: Possession of Marihuana
- Two ounces or less: Class B misdemeanor, up to 180 days in jail and a fine up to $2,000.
- More than two ounces up to four ounces: Class A misdemeanor, up to one year in jail and a fine up to $4,000.
- More than four ounces up to five pounds: state jail felony, 180 days to two years in a state jail and a fine up to $10,000.
- More than five pounds up to 50 pounds: third-degree felony, two to 10 years in prison and a fine up to $10,000.
- More than 50 pounds up to 2,000 pounds: second-degree felony, two to 20 years in prison and a fine up to $10,000.
- More than 2,000 pounds: first-degree felony, five to 99 years or life and a fine up to $50,000.
Four ounces is the line that turns a county-jail case into a state prison case. These numbers apply only to plant material.
Why Vape Cartridges and Concentrates Are Felonies
This is where Texas law catches people hardest. The statutory definition of marijuana covers the Cannabis sativa L. plant and its seeds, but it specifically excludes resin extracted from the plant and anything made from that resin.2State of Texas. Texas Health and Safety Code Section 481.002 – Definitions Hash oil, wax, dabs, shatter, and the oil inside a vape cartridge are resin derivatives, so they are not prosecuted as marijuana. They fall under Penalty Group 2 as tetrahydrocannabinols, and the penalties start at the felony level and are measured in grams.3State of Texas. Texas Health and Safety Code 481.103 – Penalty Group 2
- Less than one gram: state jail felony, 180 days to two years and a fine up to $10,000.
- One gram to less than four grams: third-degree felony, two to 10 years in prison.
- Four grams to less than 400 grams: second-degree felony, two to 20 years in prison.
- 400 grams or more: first-degree felony, five to 99 years or life and a fine up to $50,000.
A single THC vape cartridge under a gram is automatically a state jail felony, while two ounces of flower is a misdemeanor. The weight includes the oil plus any dilutants or adulterants in the cart. Someone bringing legally purchased dispensary products from another state faces the same charge as someone carrying several ounces of flower.
Giving or Selling Marijuana
Delivery is a separate offense from possession, and the thresholds are tighter.5State of Texas. Texas Health and Safety Code Section 481.120 – Offense: Delivery of Marihuana
- One-quarter ounce or less, given for free: Class B misdemeanor.
- One-quarter ounce or less, sold for money: Class A misdemeanor.
- More than one-quarter ounce up to five pounds: state jail felony.
- More than five pounds up to 50 pounds: second-degree felony.
- More than 50 pounds up to 2,000 pounds: first-degree felony.
- More than 2,000 pounds: first-degree felony, 10 to 99 years or life and a fine up to $100,000.
Handing a friend more than a quarter ounce is a state jail felony whether money changes hands or not. On the possession side, you would need more than four ounces to hit the same felony level.
Drug-Free Zone Enhancements
Any marijuana offense committed within 1,000 feet of a school, playground, youth center, or on a school bus bumps the charge up one level.6State of Texas. Texas Health and Safety Code 481.134 – Drug-Free Zones A Class B possession becomes a Class A. A Class A becomes a state jail felony. For felony-level offenses, the minimum prison term increases by five years and the maximum fine doubles.
The 1,000 feet is measured from the property line, not the building, so the zone reaches further than people expect. A narrow exception removes the enhancement for the lowest-level offense when it happens inside a private residence with no minor present.
Driver’s License Suspension After Any Conviction
A conviction for any marijuana offense, including a Class B misdemeanor, triggers an automatic six-month driver’s license suspension.7Texas Center for the Judiciary. Automatic License Suspension It applies even when the offense had nothing to do with driving. The Department of Public Safety imposes it after it receives notice of the conviction, so a defendant who pleads guilty to low-level possession often learns about the suspension only after the plea.
The Compassionate Use Program
The Texas Compassionate Use Act, in Health and Safety Code Chapter 487, allows qualifying patients to receive low-THC cannabis.8State of Texas. Texas Health and Safety Code Section 487.001 – Definitions Qualifying conditions include epilepsy and seizure disorders, multiple sclerosis, spasticity, ALS, terminal cancer, autism, and incurable neurodegenerative diseases. The program has been expanded several times since it passed in 2015, and approved products currently top out at 1% THC by weight.
There is no patient card. A registered physician enters the prescription directly into the Compassionate Use Registry of Texas (CURT), which is run by DPS, and licensed dispensing organizations look up the patient in that system before dispensing.9Texas Department of Public Safety. Compassionate Use Registry of Texas (CURT) Law enforcement can confirm a patient’s status by contacting DPS during business hours. Approved products are limited to non-smokable forms such as oils and tinctures, and only a small number of licensed dispensing organizations operate in the state.
Hemp, CBD, and Where Delta-8 Stands
Texas legalized hemp in 2019 through House Bill 1325, which added Chapter 121 to the Agriculture Code. Hemp is Cannabis sativa L. with a delta-9 THC concentration of no more than 0.3% on a dry weight basis, and the definition reaches the plant’s derivatives, extracts, cannabinoids, and isomers as long as they stay under that threshold.10State of Texas. Texas Agriculture Code Section 121.001 – Definition Growers, processors, and distributors need a Texas Department of Agriculture license and must submit products for testing.
Delta-8 THC products, which filled Texas retail shelves for years, lost their legal cover in 2025. The Department of State Health Services classified manufactured delta-8 as a Schedule I controlled substance. Hemp businesses sued and initially won an injunction blocking enforcement, but the Texas Supreme Court reversed that injunction, ruling that the commissioner acted within her authority to classify synthetic THC equivalents as controlled substances and that manufactured delta-8 is a synthetic equivalent of naturally occurring THC.11Texas Judicial Branch. Sky Marketing Corp. v. Texas Department of State Health Services The underlying case is not fully resolved; the court also ruled the plaintiffs have standing to continue their challenge on other grounds. For now, DSHS has enforcement authority over delta-8, and the product is no longer shielded by a court order.
Federal Rules That Still Apply in Texas
Federal law treats cannabis as a Schedule I substance, and that creates problems a Texas prescription cannot fix.
Firearms
Federal law bars any unlawful user of a controlled substance from possessing firearms or ammunition.12Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts That includes Compassionate Use patients, because marijuana is still Schedule I federally. ATF Form 4473 asks about controlled substance use directly, and lying on the form is itself a federal felony.
Federally Assisted Housing
HUD requires federally assisted housing to prohibit marijuana use regardless of state law. Property owners must deny admission to any household with a marijuana-using member, and current residents can be evicted for use.13U.S. Department of Housing and Urban Development. Use of Marijuana in Multifamily Assisted Properties This covers public housing, Section 8 vouchers, and other HUD-assisted properties.
Airports
TSA officers are not searching for marijuana, but they are required to report suspected legal violations to law enforcement if they find them during screening. Only products with no more than 0.3% THC on a dry weight basis are legal federally.14Transportation Security Administration. Medical Marijuana At any Texas airport, both federal and state law are stacked against carrying marijuana through the checkpoint.
