Texas drug penalty groups are legal categories that classify controlled substances under the Texas Controlled Substances Act. The penalty group and the amount possessed together determine whether a drug offense is a misdemeanor or a felony and govern the applicable punishment range. More serious penalty groups and larger amounts lead to harsher penalties.

Key Takeaways
- Texas classifies controlled substances into statutory “penalty groups.”
- In every Texas drug case, the penalty group and the alleged amount together determine whether the offense is a misdemeanor or a felony and govern the applicable punishment range.
- Two cases involving similar quantities can have radically different outcomes solely because the substances fall into different penalty groups.
How Texas Drug Charges are Determined
- The penalty group identifies how Texas law classifies the drug
- The amount determines the charge level and sentencing range
- Manufacture or delivery allegations carry higher penalties than possession
- Marijuana is treated separately and is not assigned a penalty group
- THC concentrates are usually charged as felonies under controlled substance laws
Texas drug penalty groups are defined in the Texas Controlled Substances Act:
- Penalty Group 1 — Texas Health & Safety Code § 481.102
- Penalty Group 1-A — § 481.1021
- Penalty Group 2 — § 481.103
- Penalty Group 2-A — § 481.1031
- Penalty Group 3 — § 481.104
- Penalty Group 4 — § 481.105
Marijuana is addressed separately under Chapter 481 and is not assigned a penalty group.
How Drug Charges are Determined
- If the penalty group is more severe, the charge escalates faster.
- If the alleged amount increases, the offense level increases.
- If the allegation concerns manufacture or delivery rather than possession, penalties increase substantially.
The penalty group sets the framework. The amount determines the charge level.
Penalty Group 1 (PG1) — § 481.102
Penalty Group 1 includes the highest-risk controlled substances under Texas law.
Common substances include cocaine, methamphetamine, heroin, fentanyl, oxycodone, and morphine. Even very small amounts can result in felony charges.
Penalty Group 1 — Possession Weight-to-Charge Table
| Amount possessed | Charge level | Punishment range |
| Less than 1 gram | State jail felony | 180 days to 2 years in state jail; fine up to $10,000 |
| 1 gram to < 4 grams | Third-degree felony | 2 to 10 years in prison; fine up to $10,000 |
| 4 grams to < 200 grams | Second-degree felony | 2 to 20 years in prison; fine up to $10,000 |
| 200 grams to < 400 grams | First-degree felony | 5 to 99 years or life in prison; fine up to $10,000 |
| 400 grams or more | Enhanced first-degree felony | 10 to 99 years or life in prison; fine up to $10,000 |
Penalty Group 1-A (PG1-A) — § 481.1021
Penalty Group 1-A applies exclusively to LSD.
In Texas, abuse units measure the number of individual doses of LSD rather than weight, allowing felony charges based on dosage count even when the physical amount is minimal.
Penalty Group 1-A (PG1-A) — Possession by Abuse Units
| Abuse Units | Charge Level | Punishment Range |
|---|---|---|
| Fewer than 20 units | State jail felony | 180 days to 2 years state jail; fine up to $10,000 |
| 20 to less than 80 units | Third-degree felony | 2 to 10 years prison; fine up to $10,000 |
| 80 to less than 4,000 units | Second-degree felony | 2 to 20 years prison; fine up to $10,000 |
| 4,000 or more units | First-degree felony | 5 to 99 years or life; fine up to $10,000 |
Penalty Group 2 (PG2) — § 481.103
Penalty Group 2 covers hallucinogens and powerful synthetic drugs.
Common substances include MDMA (ecstasy/molly), PCP, psilocybin mushrooms, and synthetic hallucinogens. These cases are often charged aggressively on the basis of perceived public safety risks.
Penalty Group 2 — Possession Weight-to-Charge Table
| Amount Possessed | Charge Level | Punishment Range |
|---|---|---|
| Less than 1 gram | State jail felony | 180 days to 2 years state jail; fine up to $10,000 |
| 1 gram to less than 4 grams | Third-degree felony | 2 to 10 years prison; fine up to $10,000 |
| 4 grams to less than 400 grams | Second-degree felony | 2 to 20 years prison; fine up to $10,000 |
| 400 grams or more | First-degree felony | 5 to 99 years or life; fine up to $50,000 |
Penalty Group 2-A (PG2-A) — § 481.1031
Penalty Group 2-A applies to synthetic cannabinoids such as K2 and Spice. These substances are not marijuana and are often charged more harshly than expected.
| Amount Possessed | Charge Level | Punishment Range |
|---|---|---|
| 2 ounces or less | Class B misdemeanor | Up to 180 days jail; fine up to $2,000 |
| More than 2 ounces to less than 4 ounces | Class A misdemeanor | Up to 1 year jail; fine up to $4,000 |
| 4 ounces to less than 5 pounds | State jail felony | 180 days to 2 years state jail; fine up to $10,000 |
| 5 pounds or more | Second-degree felony | 2 to 20 years prison; fine up to $10,000 |
Penalty Group 3 (PG3) — § 481.104
Penalty Group 3 primarily includes prescription medications with accepted medical use, such as Xanax, Valium, Ritalin, anabolic steroids, and low-dose codeine mixtures.
Possession is lawful only with a valid prescription.
| Amount Possessed | Charge Level | Punishment Range |
|---|---|---|
| Less than 28 grams | Class A misdemeanor | Up to 1 year jail; fine up to $4,000 |
| 28 grams to less than 200 grams | Third-degree felony | 2 to 10 years prison; fine up to $10,000 |
| 200 grams to less than 400 grams | Second-degree felony | 2 to 20 years prison; fine up to $10,000 |
| 400 grams or more | First-degree felony | 5 to 99 years or life; fine up to $50,000 |
Penalty Group 4 (PG4) — § 481.105
Penalty Group 4 is the lowest controlled-substance penalty group and often involves mixtures containing small amounts of narcotics combined with non-narcotic substances.
Possession Weight-to-Charge Table
| Amount Possessed | Charge Level | Punishment Range |
|---|---|---|
| Less than 28 grams | Class B misdemeanor | Up to 180 days jail; fine up to $2,000 |
| 28 grams to less than 200 grams | Class A misdemeanor | Up to 1 year jail; fine up to $4,000 |
| 200 grams to less than 400 grams | Third-degree felony | 2 to 10 years prison; fine up to $10,000 |
| 400 grams or more | Second-degree felony | 2 to 20 years prison; fine up to $10,000 |
Marijuana vs. THC in Texas
Marijuana is not assigned a penalty group and is charged strictly by weight.
THC concentrates—including vape cartridges, edibles, oils, and wax—are not treated as marijuana and are usually charged under Penalty Group 1 or 2 as felonies.
Hemp is legal only if it contains 0.3% or less Delta 9 THC. Legality depends on laboratory testing, not appearance. Muddying the issue further, there are different varieties of THC, including Delta 8 and THC-H.
Possession vs. Manufacture or Delivery
All tables above apply only to possession.
Manufacture, delivery, or possession with intent to deliver carries significantly higher punishment ranges.
Intent may be inferred from quantity, packaging, cash, or surrounding circumstances.
Common Misconceptions
- All drugs are punished the same — False
- Prescription drugs are legal to possess — Only with a valid prescription
- THC is treated like marijuana — False
- Small weight differences do not matter — False
