Texas Drug Penalty Groups Explained (2026 Update)

Texas drug penalty groups classify controlled substances under the Texas Controlled Substances Act. The penalty group, quantity involved, and alleged offense determine whether a drug charge is a misdemeanor or felony and the potential punishment. Possession, manufacture, and delivery can carry different penalties for the same substance.

Key Takeaways

• Texas has seven controlled substance penalty groups: 1, 1-A, 1-B, 2, 2-A, 3, and 4.
• Possession of even a small amount of a substance in certain penalty groups can result in felony charges.
• The weight of a controlled substance, including applicable adulterants and dilutants, can determine the offense level.
• Manufacturing or delivering controlled substances can carry different, often more severe, penalties than possession.
• Marijuana possession is addressed separately from the controlled-substance penalty groups.
• THC products require careful classification because marijuana, THC concentrates, and legally compliant hemp may be treated differently.

How Texas Drug Charges Are Determined

Texas classifies controlled substances under Health and Safety Code Chapter 481. Each penalty group identifies particular drugs or chemical compounds, while separate statutes establish the penalties for possessing those substances.

The classification of a drug charge depends on the substance involved, the quantity alleged, and whether the person is accused of possession, manufacture, delivery, or possession with intent to deliver.

For example, possessing less than one gram of cocaine can result in a state jail felony under Penalty Group 1. Possessing less than 28 grams of a qualifying Penalty Group 3 medication without authorization is ordinarily a Class A misdemeanor.

The tables below cover possession offenses only. They show the statutory punishment ranges before considering enhancements, probation eligibility, or other sentencing provisions.

Texas defines the penalty groups in the following statutes:

• Penalty Group 1: Texas Health & Safety Code § 481.102
• Penalty Group 1-A: § 481.1021
• Penalty Group 1-B: § 481.1022
• Penalty Group 2: § 481.103
• Penalty Group 2-A: § 481.1031
• Penalty Group 3: § 481.104
• Penalty Group 4: § 481.105

Penalty Group 1 (PG1): § 481.102

Penalty Group 1 includes substances such as cocaine, methamphetamine, heroin, oxycodone, and morphine.

Penalty Group 1-B (PG1-B): § 481.1022

Penalty Group 1-B covers fentanyl and specified fentanyl-related substances, including carfentanil and certain fentanyl derivatives.

Texas created this separate classification to address fentanyl-related controlled substances. Under § 481.115, possession of Penalty Group 1-B substances follows the same weight-based punishment tiers as Penalty Group 1.

Penalty Group 2 (PG2): § 481.103

Penalty Group 2 includes several hallucinogenic and synthetic substances, including MDMA (ecstasy), PCP, psilocybin, and tetrahydrocannabinols (THC), subject to applicable statutory exceptions.

Possession of less than one gram of a Penalty Group 2 substance can result in a state jail felony. Larger quantities carry substantially longer potential prison sentences.

Penalty Group 2-A (PG2-A): § 481.1031

Penalty Group 2-A includes specified synthetic cannabinoids, commonly associated with products marketed as K2 or Spice.

These substances are classified separately from marijuana and from THC compounds listed in Penalty Group 2.

Unlike Penalty Groups 1 and 2, Penalty Group 2-A uses ounces and pounds to establish possession penalties. Small quantities may be misdemeanors, while larger amounts can result in felony charges.

Penalty Group 3 (PG3): § 481.104

Penalty Group 3 includes certain prescription medications and controlled substances, such as alprazolam (Xanax), diazepam (Valium), methylphenidate (Ritalin), anabolic steroids, and specified codeine preparations.

Many of these substances have accepted medical uses, but possessing them without legal authorization can result in criminal charges.

For example, someone accused of possessing Xanax without a valid prescription may face a Class A misdemeanor for an amount below 28 grams. At 28 grams, the offense becomes a third-degree felony under the ordinary possession statute.

Penalty Group 4 (PG4): § 481.105

Penalty Group 4 includes certain medicinal preparations containing limited amounts of narcotic substances combined with other active ingredients. Examples include qualifying low-concentration codeine preparations.

Although Penalty Group 4 includes substances with recognized medical uses, unauthorized possession can still result in felony charges.

Possession of less than 28 grams is ordinarily a Class B misdemeanor. At 28 grams, the offense becomes a third-degree felony.

Marijuana vs. THC in Texas

Texas treats marijuana possession separately from possession of controlled substances assigned to the statutory penalty groups.

Under Health and Safety Code § 481.121, marijuana possession penalties are based primarily on weight. THC concentrates, including certain vape cartridges, oils, waxes, and edibles, may instead be prosecuted under Penalty Group 2, depending on the product's chemical composition and applicable legal exceptions.

Not every product containing THC is automatically an illegal controlled substance. Texas law recognizes hemp and certain legally authorized hemp-derived products, but classification depends on the cannabinoids present, their concentrations, and how the product was manufactured.

What is the Difference Between Marijuana and Hemp?

Texas defines hemp as cannabis containing no more than 0.3% Delta-9 THC by dry weight. However, meeting that threshold does not automatically make every cannabinoid product lawful. The product's chemical composition and applicable state and federal requirements can affect its legal status. Other cannabinoids, including Delta 8 and THC-H, raise additional classification questions.

Texas has also clarified its treatment of delta-8 THC. The Texas Department of State Health Services states that only naturally occurring trace amounts of delta-8 THC in qualifying hemp are exempt from controlled-substance status.

Federal hemp requirements are also changing. Most amendments to the federal hemp definition have been delayed until at least December 11, 2026, although certain provisions involving cannabinoids that cannot be naturally produced by cannabis are scheduled to take effect earlier.

For someone accused of possessing an illegal THC product, laboratory results may be important in determining whether the substance falls within a controlled-substance penalty group or qualifies for a statutory hemp exception.

What is the most serious drug penalty group in Texas?

Texas Penalty Groups 1, 1-A, and 1-B include substances that can result in felony charges for very small quantities. Penalty Group 1 includes cocaine and methamphetamine, Penalty Group 1-A includes LSD and certain related hallucinogens, and Penalty Group 1-B includes fentanyl and specified fentanyl derivatives. The potential punishment depends on the substance, amount, and alleged offense.

Does the amount or penalty group matter more in a Texas drug case?

Both are important. The penalty group determines which statutory punishment provisions apply, while the quantity determines the offense level within those provisions. The alleged conduct also matters because possession, manufacture, and delivery can carry different penalties.

Is possession of less than one gram of drugs a felony in Texas?

It can be. Unauthorized possession of less than one gram of a substance in Penalty Group 1, 1-B, or 2 is ordinarily a state jail felony, punishable by 180 days to two years in state jail and a fine of up to $10,000. Other penalty groups have different thresholds, and applicable statutory exceptions may affect the charge.

Is THC treated the same as marijuana in Texas?

No. Texas treats marijuana possession separately from controlled-substance possession involving THC. Certain THC concentrates, including vape cartridges, oils, and edibles, may be prosecuted under Penalty Group 2. However, products that qualify under applicable hemp laws or other statutory exceptions may be treated differently.

Can I be charged with a felony for possessing prescription medication in Texas?

Yes. Unauthorized possession of certain prescription medications can result in felony charges depending on the penalty group and quantity. For example, possessing 28 grams or more of a Penalty Group 3 substance can be a felony. A valid prescription or other legal authorization may provide a defense or statutory exception.

Can a Texas drug possession charge be dismissed?

Yes. A drug possession charge may be dismissed when prosecutors cannot prove the offense or when legal problems undermine the evidence. An attorney may challenge the legality of the search, whether the defendant knowingly possessed the substance, laboratory identification, or the alleged quantity. Depending on the case, diversion programs or other alternatives may also be available.
