Texas Controlled Substances Act: Penalties, Enhancements, and Defenses

Penalties under the Texas Controlled Substances Act range from a $500 fine at the low end to 10 to 99 years or life in prison plus a $250,000 fine for large-scale trafficking of drugs like methamphetamine, cocaine, heroin, or fentanyl. What you actually face depends on two things: which penalty group the substance falls into under Chapter 481 of the Health and Safety Code, and how much of it was involved (including any cutting agents mixed in).

How Texas Sorts Drugs Into Penalty Groups

Texas does not use the federal scheduling system for state charges. It uses its own penalty groups, and Penalty Group 1 carries the harshest consequences. Lower-numbered groups generally mean higher penalties. Marijuana sits outside this system entirely, under its own statute.

Penalty Group 1 and 1-B: cocaine, heroin, methamphetamine, fentanyl, oxycodone, hydrocodone.
Penalty Group 1-A: LSD and its chemical variants, measured in dosage units rather than weight.
Penalty Group 2: MDMA, PCP, mescaline, and certain synthetic cannabinoids.
Penalty Group 3: drugs with medical uses but abuse potential — Xanax, Valium, anabolic steroids, some codeine formulations.
Penalty Group 4: preparations containing limited quantities of narcotics, such as small amounts of codeine or difenoxin.

The weight thresholds include adulterants and dilutants. A small bag of cocaine cut with baking soda gets weighed as-is, which can push you into a much higher tier than the actual drug content would suggest.

Possession Penalties

Possession of any of these substances without a valid prescription is a criminal offense. The tier structure varies by group.

Penalty Group 1 and 1-B

Less than 1 gram: state jail felony, 180 days to 2 years, fine up to $10,000.
1 to 4 grams: third-degree felony, 2 to 10 years, fine up to $10,000.
4 to 200 grams: second-degree felony, 2 to 20 years, fine up to $10,000.
200 to 400 grams: first-degree felony, 5 to 99 years or life, fine up to $10,000.
400 grams or more: enhanced first-degree felony, 10 to 99 years or life, fine up to $100,000.

Even the smallest measurable amount is a felony.¹

Penalty Group 2

Less than 1 gram: state jail felony, 180 days to 2 years, fine up to $10,000.
1 to 4 grams: third-degree felony, 2 to 10 years, fine up to $10,000.
4 to 400 grams: second-degree felony, 2 to 20 years, fine up to $10,000.
400 grams or more: 5 to 99 years or life, fine up to $50,000.

The key difference from Group 1 is that the 4-to-400-gram range stays at second-degree felony territory rather than splitting into a first-degree tier at 200 grams.²

Penalty Group 3

Less than 28 grams: Class A misdemeanor, up to 1 year in county jail, fine up to $4,000.
28 to 200 grams: third-degree felony, 2 to 10 years, fine up to $10,000.
200 to 400 grams: second-degree felony, 2 to 20 years, fine up to $10,000.
400 grams or more: 5 to 99 years or life, fine up to $50,000.

Group 3 covers many commonly prescribed medications, so the difference between legal and criminal possession often comes down to whether you have a valid prescription in your name.³

Penalty Group 4

Less than 28 grams: Class B misdemeanor, up to 180 days in jail, fine up to $2,000.
28 to 200 grams: third-degree felony, 2 to 10 years, fine up to $10,000.
200 to 400 grams: second-degree felony, 2 to 20 years, fine up to $10,000.

This is the lightest tier of drug possession offense that still carries jail time.⁴

Marijuana Is Handled Separately

Texas has not legalized recreational marijuana. Even small amounts are criminal, and the weight tiers sit on their own statute:

2 ounces or less: Class B misdemeanor, up to 180 days in jail, fine up to $2,000.
2 to 4 ounces: Class A misdemeanor, up to 1 year in jail, fine up to $4,000.
4 ounces to 5 pounds: state jail felony, 180 days to 2 years, fine up to $10,000.
5 to 50 pounds: third-degree felony, 2 to 10 years, fine up to $10,000.
50 to 2,000 pounds: second-degree felony, 2 to 20 years, fine up to $10,000.
More than 2,000 pounds: 5 to 99 years or life, fine up to $50,000.

A single joint is enough to be charged with a Class B misdemeanor that can put you in jail and leave a permanent record. THC concentrates like wax, oil, and edibles are treated differently from plant marijuana and often fall under Penalty Group 2, so a small THC cartridge can carry the same charge as possessing ecstasy or PCP.

Manufacture or Delivery

Delivery is punished more harshly than possession at every weight level, and “delivery” under Texas law does not require a sale. Handing someone a drug, or even offering to, counts. Prosecutors use packaging, scales, and cash as evidence that someone intended to distribute rather than merely possess.

Penalty Group 1

Less than 1 gram: state jail felony, 180 days to 2 years, fine up to $10,000.
1 to 4 grams: second-degree felony, 2 to 20 years, fine up to $10,000.
4 to 200 grams: first-degree felony, 5 to 99 years or life, fine up to $10,000.
200 to 400 grams: 10 to 99 years or life, fine up to $100,000.
400 grams or more: 15 to 99 years or life, fine up to $250,000.

The jump from possession to delivery is significant. Possessing 1 to 4 grams is a third-degree felony with a 2-to-10-year range; delivering the same amount is a second-degree felony with a 2-to-20 year range. At 400 grams, the delivery minimum is 15 years.⁵

Penalty Group 3 and 4

Manufacture or delivery starts at the state jail felony level regardless of amount. There is no misdemeanor option.

Less than 28 grams: state jail felony, 180 days to 2 years, fine up to $10,000.
28 to 200 grams: second-degree felony, 2 to 20 years, fine up to $10,000.
200 to 400 grams: first-degree felony, 5 to 99 years or life, fine up to $10,000.

Possessing 20 grams of a Penalty Group 3 substance without a prescription is a Class A misdemeanor. Delivering that same 20 grams is a state jail felony. This catches people who share prescription medications without realizing what they’ve done.⁶

Sentencing Enhancements

Several circumstances push a charge above its standard range.

Drug-Free Zones

Section 481.134 of the Health and Safety Code increases the offense level for drug offenses committed near schools, playgrounds, youth centers, and public pools. A state jail felony can be punished as a third-degree felony, a third-degree as a second-degree, and so on.⁷ The enhancement applies based on location alone. You do not need to know a school is nearby.

Prior Convictions

Under the habitual offender provisions of the Penal Code, a second felony conviction can raise the minimum sentence, and a third can result in 25 to 99 years or life.⁴ Even a state jail felony can be enhanced to a third-degree felony with a prior felony on your record. Priors also weigh heavily against getting probation.

Offenses Involving Children

Manufacturing or delivering a controlled substance with a child under 18 present triggers enhanced charges under Section 481.140.⁸ A meth lab in a home with children can add years of prison time and trigger separate child endangerment charges and family court proceedings.

The Good Samaritan Defense in Overdose Cases

This provision is one of the least-known in the Act, and it can be the difference between a felony conviction and a dismissed charge. Under Section 481.115(g), you may have a legal defense against a small-amount possession charge if:

You were the first person to call for emergency medical help during an overdose;
You stayed on the scene until help arrived; and
You cooperated with medical and law enforcement personnel.

The same defense applies if you were the person overdosing and someone else called on your behalf.⁹ It does not apply if police were already arresting you or executing a search warrant when the call was made, if you were committing another offense beyond the minor possession the statute covers, or if you have already used the defense once before.

Diversion, Drug Court, and Deferred Adjudication

Not every charge ends in a conviction. Many Texas counties offer pretrial diversion programs and drug courts, typically for first-time offenders facing misdemeanors or lower-level felony drug charges. Participation involves regular drug testing, counseling or treatment, community service, and probation check-ins over a period that can run from several months to more than a year. Complete the program and the case is dismissed. Violate its terms and the original charges come back.

Deferred adjudication is a separate option. You plead guilty or no contest, but the court delays entering a formal conviction while you complete community supervision. Finish successfully and the case is dismissed without a final conviction. That dismissal can later qualify you for a nondisclosure order sealing the record from public view.

Consequences That Follow a Conviction

The sentence is only part of the picture. A drug conviction can reach into your work, your status in the country, and your property.

Employment and Professional Licensing

A felony drug conviction shows up on standard background checks and can disqualify you from professional licenses in healthcare, education, law, and real estate. Even a misdemeanor possession charge creates problems in competitive hiring.

Driver’s License Suspension

A drug conviction can trigger an automatic driver’s license suspension in Texas, separate from any DUI-related suspension, and it applies even when the offense had nothing to do with driving.

Federal Student Aid

Drug convictions no longer disqualify students from federal financial aid. As of July 1, 2023, Pell Grants and federal student loans are available regardless of a drug conviction on your record.¹⁰

Immigration

For non-citizens the stakes are especially high. Under federal immigration law, a conviction for almost any controlled substance offense makes a person inadmissible to the United States. This applies to green card holders, visa holders, and anyone seeking lawful permanent resident status. The one narrow exception involves a single offense of possessing 30 grams or less of marijuana, and even that requires a waiver with significant conditions.¹¹ If you are not a citizen, raise this with a defense attorney before any plea.

Civil Asset Forfeiture

Under Chapter 59 of the Texas Code of Criminal Procedure, law enforcement can seize cash, vehicles, and other property suspected of connection to drug activity. The seizure happens through a civil proceeding with a lower burden of proof than a criminal trial, and it can occur before any conviction. Getting the property back generally requires a separate legal action. If you are carrying a large amount of cash during a drug arrest, expect it to be seized.

Parallel Federal Prosecution

A single incident can produce both state and federal charges. Under the dual sovereignty doctrine, the double jeopardy clause does not prevent separate state and federal prosecutions for the same conduct.¹² Federal drug penalties often include mandatory minimums of 5 or 10 years for trafficking quantities of Schedule I and II substances. Federal cases typically involve larger amounts, interstate activity, or federal agents making the arrest.

Clearing a Drug Record Later

Texas offers two ways to limit the long-term damage of a drug record, and neither is available in every situation.

Expunction

An expunction removes the record of an arrest and related proceedings from public and law enforcement databases. You may qualify if your charges were dismissed, you were acquitted, you were arrested but never formally charged, or you completed a pretrial diversion program.¹³ Expunction is not available if you were convicted, and even most misdemeanor drug convictions disqualify you.

Nondisclosure Orders

If you completed deferred adjudication and the case was dismissed, you may be able to petition for a nondisclosure order. This seals the record from most public entities and private employers but not from law enforcement or licensing boards.¹⁴ Waiting periods depend on the offense. A misdemeanor nondisclosure can sometimes be filed immediately upon discharge and dismissal. For felony drug offenses, you must wait five years after discharge and dismissal before petitioning, and the court still has to find that granting the order is in the best interest of justice.

Filing fees vary by county, and most people hire an attorney to draft and file the petition. Given how heavily a visible drug record weighs on employment and housing prospects, the investment is often worth it when a case qualifies.
