Yes, THC carts are a felony in Texas. Every THC vape cartridge falls under Penalty Group 2 of the Texas Health and Safety Code, which means possession of even a single sub-gram cartridge is a state jail felony punishable by up to two years of confinement. The penalty climbs quickly with weight, and because the state weighs the entire liquid in the cartridge rather than the pure THC content, most people carrying a cart or two are already sitting on the line between a state jail felony and a third-degree felony.
Why Concentrates Are Treated Harsher Than Flower
Texas splits cannabis into two very different legal categories. The marijuana plant itself is regulated separately, and possessing two ounces or less of leafy marijuana is a Class B misdemeanor. THC oil is not treated as marijuana. Section 481.103 of the Texas Health and Safety Code places tetrahydrocannabinols other than the plant itself into Penalty Group 2, the same category as many hallucinogens.1State of Texas. Texas Health and Safety Code Section 481.103 – Penalty Group 2 Extracted oils, resins, waxes, and any concentrated form of the plant all sit inside that group.
The practical consequence is stark. The same cannabis molecule that produces a misdemeanor charge in plant form produces a felony charge in oil form. Carrying a vape pen loaded with THC oil is a fundamentally different legal situation than carrying a bag of flower, and a lot of people learn that only after they’ve been arrested.
Possession Penalties by Weight
Section 481.116 of the Health and Safety Code sets four possession tiers for Penalty Group 2 substances.2State of Texas. Texas Health and Safety Code Section 481.116 – Offense: Possession of Substance in Penalty Group 2
- Less than 1 gram is a state jail felony, punishable by 180 days to two years in a state jail facility and a fine up to $10,000.3State of Texas. Texas Penal Code 12.35 – State Jail Felony Punishment
- One gram to less than 4 grams is a third-degree felony, punishable by two to ten years in prison and a fine up to $10,000.4State of Texas. Texas Penal Code 12.34 – Third Degree Felony Punishment
- Four grams to less than 400 grams is a second-degree felony, punishable by two to 20 years in prison and a fine up to $10,000.5State of Texas. Texas Penal Code Section 12.33 – Second Degree Felony Punishment
- Four hundred grams or more is an enhanced first-degree felony, punishable by 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 vape cartridge holds about one gram of liquid. That places the typical user right at the boundary between the first and second tiers. Two or three cartridges will usually push someone into the third-degree felony range.
The Whole Cartridge Gets Weighed
This is the piece that catches almost everyone off guard. Texas weighs the entire liquid inside the cartridge, not just the pure THC. The statute expressly includes “adulterants or dilutants” in the aggregate weight used for sentencing.2State of Texas. Texas Health and Safety Code Section 481.116 – Offense: Possession of Substance in Penalty Group 2 Carrier oil, terpene blend, flavoring, and any cutting agent all count toward the total.
A cart labeled as 80% THC still weighs in at its full liquid weight for charging purposes. If the cartridge holds one gram, the state counts one gram of controlled substance. The number on the packaging and the number the prosecutor uses are not the same number.
Selling or Delivering Is Charged One Tier Higher
Anyone accused of selling, manufacturing, or intending to distribute THC cartridges is charged under Section 481.113 of the Health and Safety Code, which ratchets the penalties up.6State of Texas. Texas Health and Safety Code 481.113 – Offense: Manufacture or Delivery of Substance in Penalty Group 2 Prosecutors typically point to things like large amounts of cash, multiple devices, packaging materials, or texts discussing sales.
- Less than 1 gram: state jail felony (180 days to two years).
- One gram to less than 4 grams: second-degree felony (two to 20 years). This jumps straight past the third-degree tier that applies to simple possession.
- Four grams to less than 400 grams: first-degree felony (five to 99 years or life).
- Four hundred grams or more: enhanced first-degree felony with a minimum of 10 years in prison 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
Every bracket is one tier harsher than the possession equivalent. A person carrying a handful of cartridges can end up facing a potential life sentence if the state believes those cartridges were meant for sale.
Delta-8 and Hemp Carts Are No Longer a Workaround
For several years, Delta-8 THC cartridges occupied a legal gray zone. After 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, hemp-derived vape products spread across retail shelves.7Texas Legislature Online. Texas House Bill 1325 – Relating to the Production and Regulation of Hemp Sellers argued Delta-8 fell outside the controlled substance definition because it isn’t Delta-9.
That window has effectively closed. In September 2025, Texas law made it a Class A misdemeanor to sell any e-cigarette or vape product containing cannabinoids, hemp-derived Delta-8 included. 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, effectively banning smokable hemp products too.8Texas State Law Library. Consumable Hemp Products – Cannabis and the Law Separate rules that took effect in January 2026 prohibit selling consumable hemp products to anyone under 21.
You can no longer legally buy a cannabinoid vape cartridge at a Texas retail store, whether it’s marketed as Delta-8, Delta-9, or anything else. A smoke shop selling a Delta-8 cart is committing a misdemeanor. And if a cart contains Delta-9 THC above the 0.3% threshold, the person holding it faces the same Penalty Group 2 felony charges as any other THC concentrate. Testing the specific cannabinoid content requires a lab, and officers in the field don’t carry lab equipment. An arrest can happen first, with results sorted out later.
The Compassionate Use Exception
Texas has a narrow medical cannabis program. Under the Compassionate Use Act, patients with qualifying conditions can receive a prescription for low-THC cannabis from a registered physician, 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 program only covers products from licensed dispensaries prescribed by a physician registered with the Compassionate Use Registry. Buying a cart from a friend, an unlicensed source, or another state doesn’t qualify no matter what medical condition you have.
Deferred Adjudication for First-Time Offenders
A felony arrest doesn’t have to end in a felony conviction. Texas judges can offer deferred adjudication for most first-time drug felony charges. You plead guilty or no contest, the judge withholds a final conviction, and you serve a period of community supervision with conditions like drug testing, counseling, and check-ins. Complete the supervision and the case is dismissed without a final conviction on your record.10Office of Court Administration. Deferred Adjudication – Expunctions and Non-Disclosure
Deferred adjudication is not available for every drug charge. Certain enhancements, like a drug-free zone finding on a repeat offense, take it off the table. Even when supervision ends without a conviction, the arrest and plea stay visible on your record unless you obtain a nondisclosure order, so employers running background checks can often still see the charge.
Consequences That Outlast the Sentence
A felony drug conviction reshapes your life well after any confinement or supervision ends.
Firearms
A Texas felon cannot possess a firearm for five years after completing the sentence, including any parole or community supervision. After those five years, state law only allows possession inside your own home.11State of Texas. Texas Penal Code 46.04 – Unlawful Possession of Firearm Violating that is itself a third-degree felony. Federal law is stricter and generally bars felons from possessing firearms at all.
Voting
You cannot register to vote while serving a felony sentence, whether you’re imprisoned, on parole, or on community supervision. The right is restored automatically once every part of the sentence is complete.12Texas Secretary of State. Effect of Felony Conviction on Voter Registration Deferred adjudication that ends in dismissal doesn’t count as a final conviction and doesn’t affect voting eligibility.
Employment and Housing
A felony drug record shows up on standard background checks and can disqualify applicants from jobs, professional licenses, and rentals. Texas has no 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 particularly hard to enter with a drug felony.
Immigration
For non-citizens, a drug felony can be devastating. A controlled substance conviction generally makes a lawful permanent resident deportable and can permanently bar an undocumented person from obtaining legal status. Immigration law carries a single automatic exception for a conviction involving 30 grams or less of marijuana, and that exception does not cover THC concentrates in Penalty Group 2. Even without a conviction, immigration authorities can act on a formal admission of drug use or a reasonable belief that someone has been involved in trafficking.
Federal Land and Airports
State penalties aren’t the whole picture. Carrying a THC cartridge onto federal property, including national parks, military installations, and federal courthouses, brings federal law into play, where cannabis is illegal in every form regardless of state law.
Airports are the most common trap. TSA operates under federal authority, and while agents are primarily looking for security threats, any THC cart they find during screening gets handed off to law enforcement. Depending on the airport and the responding agency, that can mean state charges, federal charges, or both. Flying out of a Texas airport with a THC cartridge in your bag is a direct route to a felony arrest.
