What Are Texas Drug Penalty Groups? PG1 to PG4 Explained
Texas drug penalty groups are the classification system that determines what you are charged with and how much prison time you face. Every controlled substance in Texas is assigned to a penalty group under Chapter 481 of the Texas Health and Safety Code. The group sets the type of charge. The weight sets the punishment range.
Most people search for “PG1 to PG4,” and that shorthand covers the groups you’re most likely to encounter. Texas actually maintains seven: Penalty Groups 1, 1-A, 1-B, 2, 2-A, 3, and 4. Marijuana sits outside the system entirely, with its own separate rules.
Two numbers decide almost everything about a Texas drug charge: which group the substance falls into, and what the lab report says it weighed.
How Texas Drug Penalty Groups Work
The group reflects how Texas views a substance’s abuse potential and accepted medical use. Group 1 substances carry the harshest treatment. Group 4 carries the lightest.
Weight then determines the offense level within that group. The same substance can be a state jail felony or a first-degree felony depending entirely on quantity.
One detail catches people off guard more than any other: Texas weighs the entire mixture, including adulterants and dilutants. Cutting agents, carrier substances, and filler all count toward the total. A gram of cocaine at low purity is charged as a full gram. The lab-report weight is what controls, and it is almost always higher than the amount of actual drug.
The Seven Texas Penalty Groups
Penalty Group 1
The broadest and most heavily penalized group. Common PG1 substances include heroin, cocaine, methamphetamine, oxycodone, hydrocodone (outside PG3 and PG4 preparations), morphine, PCP, ketamine, and GHB.
Possession penalties – verified against Tex. Health & Safety Code 481.115:
| Amount | Offense level | Punishment range |
|---|---|---|
| Less than 1 gram | State jail felony | 180 days – 2 years state jail |
| 1 to less than 4 grams | Third-degree felony | 2 – 10 years |
| 4 to less than 200 grams | Second-degree felony | 2 – 20 years |
| 200 to less than 400 grams | First-degree felony | 5 – 99 years or life |
| 400 grams or more | Enhanced first-degree felony | 10 – 99 years or life, fine up to $100,000 |
Penalty Group 1-A
Covers LSD and NBOMe compounds. This group is measured in abuse units, not weight.
Possession tiers run from fewer than 20 abuse units (state jail felony) up through 8,000 or more (15 to 99 years or life).
Penalty Group 1-B
Created specifically for fentanyl and its analogs, including carfentanil, alfentanil, and sufentanil.
Possession penalties for PG1-B are the same as Penalty Group 1 – § 481.115 covers both groups in a single statute. Delivery of a PG1-B substance carries its own steeper schedule with higher minimums and fines than PG1 delivery.
Penalty Group 2
Includes psilocybin mushrooms, MDMA (ecstasy), mescaline, DMT, cathinones, PCP analogs, and THC concentrates.
That last item matters enormously and surprises almost everyone. THC vape cartridges, wax, oil, and edibles are not charged as marijuana. They are Penalty Group 2 substances, which means felony exposure at any amount. A cartridge that would be a misdemeanor as plant material becomes a felony as concentrate.
Possession penalties – verified against Tex. Health & Safety Code § 481.116:
| Amount | Offense level | Punishment range |
|---|---|---|
| Less than 1 gram | State jail felony | 180 days – 2 years state jail |
| 1 to less than 4 grams | Third-degree felony | 2 – 10 years |
| 4 to less than 400 grams | Second-degree felony | 2 – 20 years |
| 400 grams or more | First-degree felony | 5 – 99 years or life, fine up to $50,000 |

Penalty Group 2-A
Synthetic cannabinoids – K2, Spice, and similar formulations. The statute defines these by chemical structure rather than by name, so new variants are automatically covered.
PG2-A is the one group in this range where small quantities are misdemeanors rather than felonies.
Tiers reportedly start at 2 ounces or less (Class B misdemeanor), rising through more than 2,000 pounds.
Penalty Group 3
Prescription medications with moderate abuse potential: alprazolam (Xanax), diazepam (Valium), clonazepam (Klonopin), methylphenidate (Ritalin), barbiturates, and anabolic steroids.
Holding a friend’s Xanax without your own prescription is a Penalty Group 3 offense.
Less than 28 grams is reportedly a Class A misdemeanor, with felony tiers above that.
Penalty Group 4
Limited quantities of narcotics compounded with non-narcotic active ingredients, such as certain codeine and dihydrocodeine preparations. These carry the lightest exposure of any penalty group.
Less than 28 grams is reportedly a Class B misdemeanor.
Where Marijuana Fits
Marijuana is not in any penalty group. It’s handled separately under § 481.121 and measured in ounces and pounds rather than grams. Possession of two ounces or less is a Class B misdemeanor.
The concentrate distinction is where cases go sideways. Plant material follows the marijuana statute. THC extracts follow Penalty Group 2. Same plant, entirely different exposure. Our Fort Worth marijuana crimes lawyers handle both.
Two Defenses Written Into the Statute
Valid prescription. Every possession statute in Chapter 481 excludes substances obtained under a valid prescription from a practitioner acting in the course of professional practice.
Good Samaritan defense. For the lowest tier of each penalty group, it is a defense that you were the first person to request emergency medical assistance for a possible overdose, remained on the scene, and cooperated with responders – or that you were the overdose victim. The defense does not apply if an officer was already arresting you or executing a search warrant when the call was made, and other statutory exclusions apply.
Why the Charge on the Paperwork Isn’t the Final Answer
A penalty group and a weight produce a charge. They don’t produce an outcome.
Lab testing gets challenged. Aggregate weight calculations get challenged. Searches get suppressed. Knowledge and control get contested when a substance is found in a shared car or apartment. And for certain lowest-tier state jail felony possession offenses, Texas law may require community supervision rather than confinement.

Frequently Asked Questions
How many drug penalty groups does Texas have?
Texas has seven: Penalty Groups 1, 1-A, 1-B, 2, 2-A, 3, and 4. People commonly refer to “PG1 through PG4,” but 1-A (LSD), 1-B (fentanyl), and 2-A (synthetic cannabinoids) are separate groups with their own penalty schedules. Marijuana is handled outside the penalty group system.
Which penalty group is fentanyl in Texas?
Fentanyl and its analogs are in Penalty Group 1-B, a group the Legislature created specifically for them. Possession penalties match Penalty Group 1, and delivery carries its own enhanced schedule with higher minimum sentences.
Are THC vapes and edibles treated as marijuana in Texas?
No. THC concentrates, vape cartridges, wax, and edibles are Penalty Group 2 substances, not marijuana. That means felony exposure at any amount, even where the same THC as plant material would be a misdemeanor.
Does the weight include the whole mixture?
Yes. Texas measures aggregate weight including adulterants and dilutants. Cutting agents and carrier substances count toward the total, so the lab-report weight that determines your charge is usually higher than the amount of actual controlled substance.
Is possession of a Penalty Group 3 drug a felony?
Not always. Smaller amounts of Penalty Group 3 substances such as Xanax or Valium held without a prescription are charged as misdemeanors, with felony tiers applying at higher weights. Penalty Groups 1, 1-B, and 2 are felonies at any amount.
