Yes, THC carts are a felony in Texas. A vape cartridge filled with THC oil falls under Penalty Group 2 of the Texas Health and Safety Code, which means even a single cart with less than a gram of liquid is a state jail felony punishable by up to two years of confinement and a fine as high as $10,000. The penalty climbs quickly from there with weight, and a 2025 law change has shut down the hemp-shop workaround that used to protect Delta-8 products.
Why a Cart Is a Felony When Flower Often Isn’t
Texas treats THC oil and plant marijuana as two different substances. Section 481.103 of the Health and Safety Code places tetrahydrocannabinols other than the marijuana plant itself into Penalty Group 2, the same category as hallucinogens.1State of Texas. Texas Health and Safety Code Section 481.103 – Penalty Group 2 That category covers extracted oils, resins, waxes, and any concentrated form of the plant.
The split has a real consequence. Possessing two ounces or less of leafy marijuana is a Class B misdemeanor. The same weight in oil form is a felony. Carrying a vape pen loaded with THC oil is a fundamentally different legal situation than carrying a bag of flower, even if the amount of actual THC is similar.
Possession Penalties by Weight
Section 481.116 ties the charge to the total weight of the substance across four tiers.2State of Texas. Texas Health and Safety Code Section 481.116 – Offense: Possession of Substance in Penalty Group 2
- Less than 1 gram: state jail felony. 180 days to two years in a state jail facility, with a possible fine up to $10,000.3State of Texas. Texas Penal Code 12.35 – State Jail Felony Punishment
- 1 gram to less than 4 grams: third-degree felony. Two to ten years in prison and a possible fine up to $10,000.4State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment
- 4 grams to less than 400 grams: second-degree felony. Two to 20 years in prison and a possible fine up to $10,000.5State of Texas. Texas Penal Code Section 12.33 – Second Degree Felony Punishment
- 400 grams or more: enhanced first-degree felony. Five to 99 years or life in prison, and a fine up to $50,000.2State of Texas. Texas Health and Safety Code Section 481.116 – Offense: Possession of Substance in Penalty Group 2
A standard disposable cart holds about one gram of liquid, which puts most people right at the line between a state jail felony and a third-degree felony. Two or three carts easily pushes someone into the third-degree range.
How the Weight Is Calculated
This is where exposure gets underestimated. Texas weighs the entire cartridge liquid, not just the pure THC. The statute explicitly includes “adulterants or dilutants” in the aggregate weight.2State of Texas. Texas Health and Safety Code Section 481.116 – Offense: Possession of Substance in Penalty Group 2 Every drop of carrier oil, terpene blend, flavoring, and cutting agent counts toward the total.
A cart advertised at 80% THC still weighs in at its full liquid weight for sentencing. One-gram cartridge, one gram of controlled substance. The number on the packaging and the number the prosecutor uses are not the same thing.
When It Becomes a Delivery Charge
If prosecutors believe the carts were meant for sale, the charge shifts to Section 481.113, and every tier moves up.6State of Texas. Texas Health and Safety Code 481.113 – Offense: Manufacture or Delivery of Substance in Penalty Group 2 Investigators look for cash, multiple devices, packaging materials, or text messages discussing sales.
- Less than 1 gram: state jail felony (180 days to two years).
- 1 gram to less than 4 grams: second-degree felony (two to 20 years). This jumps directly past the third-degree tier that applies to possession.
- 4 grams to less than 400 grams: first-degree felony (five to 99 years or life).
- 400 grams or more: enhanced first-degree felony with a minimum of 10 years and a fine up to $100,000.6State of Texas. Texas Health and Safety Code 481.113 – Offense: Manufacture or Delivery of Substance in Penalty Group 2
Possessing one to four grams is a third-degree felony; delivering the same amount is a second-degree felony. That one-tier escalation at every weight bracket is how someone carrying a handful of cartridges can end up looking at a potential life sentence.
What About Delta-8 and Hemp Carts
For several years, Delta-8 carts sat in a gray area. The federal 2018 Farm Bill and Texas House Bill 1325 legalized hemp, defined as cannabis with no more than 0.3% Delta-9 THC on a dry weight basis, and sellers argued Delta-8 products derived from legal hemp fell outside the controlled substance definition.7Texas Legislature Online. Texas House Bill 1325 – Relating to the Production and Regulation of Hemp
That window has closed. In September 2025, Texas law made it a Class A misdemeanor to sell any e-cigarette or vape product containing cannabinoids, including hemp-derived ones like Delta-8. In March 2026, the Texas Department of State Health Services adopted a rule that counts both Delta-9 THC and THCA when calculating whether a hemp product exceeds the 0.3% threshold, which effectively bans smokable hemp products as well.8Texas State Law Library. Consumable Hemp Products – Cannabis and the Law Rules effective in January 2026 also prohibit selling consumable hemp products to anyone under 21.
Practically, you can no longer legally buy any cannabinoid vape cartridge at a Texas retail store. If a cart contains Delta-9 THC above the 0.3% threshold, the person holding it faces the same Penalty Group 2 felony as any other THC concentrate. Testing the specific cannabinoid content is the only way to tell a legal hemp product from a controlled substance, and officers in the field don’t carry lab equipment. An arrest can happen first, with lab results sorted out later.
The Compassionate Use Exception
Texas allows a narrow medical cannabis program. Under the Compassionate Use Act, patients with qualifying conditions can get a prescription for “low-THC cannabis,” defined as a product containing no more than 10 milligrams of tetrahydrocannabinols per dosage unit.9Texas State Law Library. Cannabis and the Law – Compassionate Use Program Qualifying conditions include epilepsy, cancer, PTSD, chronic pain, autism, multiple sclerosis, and terminal illness, among others.
The exception is tight. The prescription has to come from a physician registered with the Compassionate Use Registry, and the product has to come from a licensed dispensary. Buying a THC cart from a friend, an unlicensed source, or another state does not qualify, regardless of your medical condition.
Deferred Adjudication for First-Time Offenders
A felony conviction is not automatic after an arrest. Texas judges can offer deferred adjudication for most first-time drug felonies. You plead guilty or no contest, the judge delays entering a final conviction, and you serve a period of community supervision with conditions like drug testing, counseling, and check-ins. Finish successfully and the case is dismissed without a final conviction.10Office of Court Administration. Deferred Adjudication – Expunctions and Non-Disclosure
It is not available in every situation. A repeat drug offense enhanced with a drug-free zone finding, for example, is excluded. And even when deferred adjudication ends without a conviction, the arrest and plea stay visible on your record unless you later obtain a nondisclosure order. Better than a conviction, but not the same as the whole thing disappearing.
Collateral Consequences of a Felony Drug Conviction
A felony drug conviction in Texas sets off a chain of consequences that outlast the sentence itself.
Firearms
A convicted felon in Texas cannot possess a firearm for five years after completing their sentence, including any parole or community supervision. After those five years, possession is only legal inside your own home.11State of Texas. Texas Penal Code 46.04 – Unlawful Possession of Firearm Violating that restriction is a third-degree felony, carrying another two to ten years. Federal law is stricter and generally bars felons from possessing firearms entirely.
Voting Rights
You cannot register to vote in Texas while serving a felony sentence, including imprisonment, parole, and community supervision. Your right to vote is restored once you complete every part of the sentence.12Texas Secretary of State. Effect of Felony Conviction on Voter Registration If you got deferred adjudication and the case was dismissed, that is not a final conviction and your voting eligibility is unaffected.
Employment, Housing, and Licensing
A felony drug record shows up on standard background checks and can disqualify you from many jobs, professional licenses, and rental applications. Texas does not have a statewide “ban the box” law for private employers, so most companies can ask about felony history on an application. Healthcare, education, and law enforcement are especially hard to enter with a drug felony.
Immigration
For non-citizens, a drug felony is particularly severe. A controlled substance conviction generally makes a lawful permanent resident deportable and can permanently bar an undocumented person from obtaining legal status. The one automatic exception in immigration law is for a single conviction involving 30 grams or less of marijuana, and that exception does not cover THC concentrates classified under Penalty Group 2. If the conviction qualifies as a drug trafficking aggravated felony, it bars nearly all forms of immigration relief. Even without a conviction, immigration authorities can act on a formal admission to drug use or a reasonable belief that someone has been involved in drug trafficking.
Federal Land and Airports
State penalties aren’t the only concern. Bringing a THC cartridge onto federal property — national parks, military installations, federal courthouses — triggers federal criminal law, under which cannabis remains illegal in all forms.
Airports are the most common trap. TSA operates under federal authority, and while agents are primarily looking for security threats, a THC cart found during screening gets referred to law enforcement. Depending on the airport and the responding agency, that can mean state charges, federal charges, or both. Flying with a THC cartridge out of any Texas airport is a fast path to a felony arrest.
