What Is the Legal Definition of a Drug Crime in Texas?

A drug crime in Texas refers to any unlawful conduct involving a controlled substance, including possession, manufacturing, delivery (distribution), or acquisition by fraud.

Under Tex. Health & Safety Code § 481.002, a controlled substance is defined as:

“A substance, including a drug, an adulterant, or a dilutant, listed in Schedules I through V or Penalty Groups 1 through 4.”

To learn more about the legal definitions and statutory terms that form the basis of all Texas drug prosecutions, see Texas Legal Definition of Drug Crimes.

How Are Drugs Classified Under Texas Law?

Texas categorizes controlled substances by Penalty Groups — a system that impacts the severity of charges and potential sentencing. These groups include everything from street drugs like heroin and methamphetamine to commonly prescribed medications like Xanax or hydrocodone.

For a detailed breakdown of which substances fall into which group — and why that matters — visit Types of Controlled Substances Under Texas Law (Penalty Groups Explained).

In short:

• Penalty Group 1 includes cocaine, heroin, meth, and fentanyl — the most severe.
• Penalty Group 1-A covers LSD and other hallucinogens.
• Penalty Group 2 includes ecstasy, PCP, and mushrooms.
• Penalty Group 3 includes prescription drugs like Xanax and Valium.
• Penalty Group 4 includes compounds with codeine or morphine in lower concentrations.

The classification determines the minimum and maximum penalties, which can range from a Class B Misdemeanor to a First-Degree Felony.

What’s the Difference Between Possession, Distribution, and Manufacturing?

The conduct involved in a drug offense — not just the drug itself — is central to how prosecutors file charges.

See Difference Between Possession, Distribution, and Manufacturing Charges for a detailed look at how these categories are defined under Texas law.

Possession

Defined as “actual care, custody, control, or management” of a drug. Even being near a substance in a car or home can lead to charges based on constructive possession.

Distribution (Delivery)

Defined as the transfer of a controlled substance to another, whether by sale or gift. Prosecutors often charge possession with intent to deliver based on packaging materials, cash, or digital messages — even without a completed sale.

Manufacturing

Involves the production or chemical synthesis of controlled substances. This includes not just meth labs, but also growing marijuana or altering prescription drugs.

When Does a Drug Offense Become a Felony?

Even small amounts of certain drugs, particularly those in Penalty Group 1 or 2, can lead to State Jail Felony charges. Larger quantities or intent to distribute can rapidly escalate to Second- or First-Degree Felonies, with potential sentences ranging from 2 years to life in prison.

To explore thresholds, enhancements, and aggravating factors, read What Makes a Drug Crime a Felony in Texas?

Factors that elevate drug charges to felonies include:

• Drug type and amount
• Presence in a drug-free zone
• Distribution to a minor
• Prior convictions

How Do Drug Arrests Typically Happen in Texas?

Drug arrests in Texas occur in a variety of scenarios, many beginning with a traffic stop, a search warrant, or a controlled buy. Law enforcement often relies on confidential informants, surveillance, and field testing before making an arrest — but many of these procedures raise Fourth Amendment issues.

To understand the most common arrest patterns and how they unfold in different counties, see Common Drug Crime Arrest Scenarios in Harris and Fort Bend Counties.

These include:

• Vehicle searches after routine stops
• Home raids with or without warrants
• Sting operations
• Arrests at parties or public events
• Workplace or probation compliance checks

What Happens After You’re Arrested for a Drug Crime?

If you’re arrested in Galveston or Brazoria County, your case will proceed through booking, bail, arraignment, discovery, pretrial motions, and potentially trial or plea negotiation.

Every stage is critical, and early intervention by an experienced lawyer near you can dramatically impact your outcome.

Key steps include:

• Bond hearings and magistrate review
• Evidence review and suppression motions
• Plea bargain vs. trial strategy
• Pretrial diversion and probation eligibility

What About Prescription Drug Charges?

Many defendants are surprised to face serious criminal charges for prescription medications they believe are “legal.” But possessing someone else’s medication without a valid prescription — or obtaining drugs through fraud, forgery, or doctor shopping — is a criminal offense.

Even small quantities of Xanax, Adderall, or hydrocodone can lead to felony possession or intent to deliver charges, especially if prosecutors allege unlawful distribution.

Can You Be Charged Just for Drug Paraphernalia or Residue?

Yes. Even if no drugs are recovered, you can still be arrested for:

• Drug residue (trace amounts on pipes, baggies, or syringes)
• Drug paraphernalia (scales, grinders, rolling papers)

Residue charges are often State Jail Felonies, while paraphernalia charges are Class C Misdemeanors, yet both can affect your record and future legal exposure.

Is Marijuana Still Illegal in Texas? Yes — and THC Concentrates Are Treated Even More Harshly

Although some Texas cities have adopted more lenient approaches, marijuana remains illegal statewide. More importantly, THC oils, waxes, edibles, and vape cartridges are not classified as marijuana — they fall under Penalty Group 2, carrying felony-level charges even for small quantities.

To understand possession penalties, medical marijuana exceptions, and local diversion programs, see Marijuana Charges in Texas: Current Laws and Penalties.

How Are Drug Crimes Classified in Court?

Texas courts determine how cases are charged and sentenced based on:

• Offense classification (misdemeanor, state jail felony, 3rd-, 2nd-, or 1st-degree felony)
• Penalty Group and weight
• Enhancements or prior convictions

Classification affects where your case is filed, whether you’re eligible for diversion or probation, and what sentencing range applies.
